    Quantification and characterization of nutrients in Senegalia mellifera milled biomass, feed intake and nitrogen balance in female Boer goats fed with Senegalia mellifera bush-based feeds
    (International Journal of Agricultural Research and Review, 2024) Epafras, A.; Mupangwa, Johnfisher; Charamba, Vonai; De la Puerta, M. L. F.
    The objectives of this study were to quantify and characterise the nutritional content of milled Senegalia mellifera milled biomass obtained from nine blocks at Neudamm Farm and to determine the dry matter intake (DMI), apparent digestibility and nitrogen retention in female Boer goats fed with Senegalia mellifera bush based feeds. Wood ash (WA), polyethylene glycol (PEG, 6 000) and biochar were evaluated as tannin deactivation methods. The milled biomass of S. mellifera was mixed using a clean concrete mixer with the following ingredients: yellow maize meal, liquid molasses; Marula oil press cake and coarse salt to formulate a complete diet with 14% CP and 11MJ ME/kg. Detannification treatment methods were added at a level of 5 g per day during feeding time. We used eight (8) female Boer goats weighing an average of 31.5 kg (± 2.5 kg) for the feeding experiment. We penned the goats individually in metabolic cages. Clean water was available ad libitum to the goats during the entire feeding experiment. The goats were fed in a 4x4 cross over Latin square design with four periods of experimental feeding. Each period lasted for 17 days, resulting in 68 days of experimental feeding. The goats were fed twice daily at 09:00h and 16:00h. The level of dry matter (DM) of feed offered was 4% of body weight. The results obtained in this study showed that there was a significant difference (p <0.05) in the chemical composition of Senegalia mellifera milled biomass harvested from the nine blocks at Neudamm Farm. The CP content of Senegalia mellifera milled biomass ranged from 9.39 to 9.68 %DM while the NDF and ADF ranged from 59.17 to 64.33%DM and 43.77 to 48.01%DM, respectively. The condensed tannins (CT) content from all blocks did not differ (p >0.05) and had a mean of 0.02 to 0.03%DM as leucocyanidin equivalent (LE Absorbance at 550 nm). The apparent digestibility coefficients of DM, OM and NDF were not significantly different among treatments and the control diet (p >0.05). Goats fed biochar treated diet had the highest nitrogen intake of 13.74g/d (p <0.05), faecal nitrogen of 8.43g/d (p <0.05) and nitrogen retention of 5.11g/d (p <0.05), while goats fed the control feed (CNT), PEG and WA were similar (p >0.05). All treatments resulted in a positive nitrogen retention (p >0.05) with mean values ranging from 3.79 to 5.11 g/d. The study concluded that, there was a significant difference (p <0.05) in the chemical composition of S. mellifera milled biomass collected from nine blocks at Neudamm Farm. Given the high CP content of the S. mellifera, this fodder resource can be considered a suitable supplement for poor quality (low N content) natural pastures and crop residues such as grass hay, straw and stover. The study also concluded that, there was a significant difference (p <0.05) in the DMI, and nitrogen balance in Boer goats fed with A. mellifera feeds treated with Wood ash (WA), Polyethylene glycol (PEG, 6 000) and Biochar (BIO). The study therefore recommends that each detannification method should be tested at different rates of inclusion in S. mellifera bush based feed resources

    Climate change adaptation strategies among smallholder livestock farmers in Namibia's Omaheke Region, Namibia
    (Discover Sustainability, 2025) Siririka, Ndjipua Avihe Tjaondjo; Charamba, Vonai; Mupangwa, Johnfisher; Shipandeni, Maria N. T.; Kahumba, Absalom
    The challenges of climate change are continuously increasing, constituting a major threat to livestock production, which is more than a socio-economic cornerstone in Namibian rural communal farmers, contributing approximately two-thirds of the country’s agricultural GDP. Climate variability, which may be in the form of drought, very high temperatures, floods and frosts has been reported to have detrimental effects on feed and water availability, leading to reduced livestock weight, growth, production and reproductive performance, and ultimately high mortality. Understanding smallholder farmers’ socio-psychological antecedents such as knowledge, attitudes and perceptions and the way they influence their level of adaptation to CC mitigation strategies needs to be assessed, as it guides CC policy formulation and intervention programmes. The study investigated CC perception and adaptation strategies for livestock farmers in Omaheke Region. Data were gathered from (n=80) purposively sampled farmers in Epukiro and Otjombinde constituencies based on livestock ownership. The study revealed that 93.8% of the respondents were aware that the climate is changing, with attributes such as very high and very low temperatures, high and low rainfall, and drought having been noticed. Climate change has been attributed to both human and natural activity. The study observed that the implementation of CC adaptation strategies in livestock agriculture is low, thus recommends that the improvement of adaptation techniques involving employing extension services, promotion of farmer-to-farmer extension, and utilization of various information sources of climate knowledge, such as farmers’ associations and social organizations, should be the future policy priority

    Indigenous knowledge of browse species and nutritional quality of dominant indigenous browse species in the Kavango West Region of Namibia
    (Discover Sustainability, 2024) Hamukwaya, Rosa N.; Charamba, Vonai; Kahumba, Absalom; Shipandeni, Maria N. T.; Mupangwa, Johnfisher
    Livestock production is crucial to the livelihoods of rural Namibians but highly constrained by feed shortages due to climate change and bush encroachment. The study investigated the grazing and feeding practices and indigenous knowledge of browsable and non-browsable species by interviewing 30 small-scale farmers in the Kavango West Region. It assessed the nutritive value for the three most commonly identified browsable species. The study observed that livestock relies on communal rangeland, roadside, and riverside grazing, with supplements from crop residues during the dry seasons. However, most farmers experience feed shortages mainly in the dry season, which results in decreased livestock productivity. Farmers are knowledgeable on browsable and non-browsable woody species in their locality, but most do not harvest pods, leaves and twigs to supplement their animals in the dry season, citing labour shortage, and they are not aware that the bush species resources can be harvested and be used during seasons when feed resources are scarce. The nutritive value analysis indicated that there is a need for strategic supplementation of the browsable species for them to be effectively utilised as livestock feed, thus farmers must be capacitated on when and how to utilise these species when herbaceous pasture grasses and legumes are senescent as well as how to harvest forage alongside rivers and roads for stall feeding to avoid accidents. Our findings will be important for policy formulation in trying to come up with better ways of mitigating the consequences of climate change

    Foliar nutrient content responses to bio-inoculation of arbuscular mycorrhizal fungi and Rhizobium on three herbaceous forage legumes
    (Frontiers, 2023) Mpongwana, Sanele; Manyevere, Alen; Mupangwa, Johnfisher; Mpendulo, Conference Thando; Mashamaite, Chuene Victor
    Smallholder livestock production in the Eastern Cape Province of South Africa has been hampered by a lack of high-quality feed. As such, improving ruminant nutrition using optimized production of herbaceous forage legumes has been suggested. However, the production of forage legumes for livestock feed is poor in communal areas in the province due to the necessity to use high levels of chemical fertilizers to provide high-quality feed that meets animal nutrient demands. The current study aimed at investigating the effects of arbuscular mycorrhizal fungi (AMF) and Rhizobium inoculation on the chemical composition of three herbaceous forage legumes, namely, Vigna unguiculata (cowpea), Lablab purpureus (lablab), and Mucuna pruriens (mucuna). The field trials were established over two growing seasons (2017/2018 and 2018/2019) at the University of Fort Hare Research Farm (South Africa) and were carried out as a 3 x 2 x 2 factorial experiment arranged in a randomized complete block design (RCBD) with 12 treatments that were replicated 4 times. The 12 treatments included three legume species (cowpea, lablab, and mucuna), two AMF (with and without AMF inoculation), and two Rhizobia inoculations (with or without). The results showed that the dual inoculation of AMF and Rhizobia bacteria significantly (p < 0.05) increased the contents of crude protein, neutral detergent fiber and acid detergent fiber, hemicellulose, ash, magnesium (Mg), phosphorus (P), calcium (Ca), zinc (Zn), and iron (Fe) of three herbaceous forage legumes. Furthermore, solo inoculation with AMF or Rhizobia bacteria resulted in substantially higher potassium (K), Ca, and Mg cation ions, and Ca/P, Zn, manganese (Mn), and Fe concentrations in forage legumes than in other treatments. In conclusion, the dual inoculation produced optimal nutrient accumulation in both growing seasons when compared to single inoculation and uninoculated forages. Therefore, this could assist in alleviating livestock malnutrition in smallholder farming

    Improving soil fertility through dual inoculation with arbuscular mycorrhizal fungi and Rhizobium on a eutric cambisol cultivated with forage legumes in a semi-arid region
    (ScienceDirect, 2024) Mpongwana, Sanele; Manyevere, Alen; Mupangwa, Johnfisher; Mpendulo, Conference Thando; Mashamaite, Chuene Victor
    The Sub-Saharan region of southern Africa is characterized by high temperatures, low rainfall, and poor land-use management practices such as continuous cropping without replenishment of soil nutrients. The combination of these factors has resulted in nutrient depletion and land degradation. The current study aimed at investigating the effect of arbuscular mycorrhizal fungi (AMF) and Rhizobium bacteria inoculation on soil chemical properties in field-grown forage le gumes, namely, Mucuna pruriens (mucuna), Lablab purpureus (lablab) and Vigna unguiculata (cowpea), in the semi-arid region of the Eastern Cape Province (South Africa). Forage legumes were inoculated with the AMF species Paraglomus occulum and the Rhizobia bacteria species Bradyrhizobium strain and grown for 120 days. Soil samples were collected in the following sequence: prior to planting, before flowering and after harvesting the forage legumes in each of the two seasons (2017/2018 and 2018/2019) and soil chemical properties were determined using standard procedures. The results showed that the addition of dual inoculation over time greatly improved soil chemical properties when compared to the control treatment. This was advocated by the significant (P ≤ 0.05) increase in soil pH, soil organic carbon, soil organic matter, total nitrogen, phosphorus, calcium, potassium, magnesium, sodium, sulfur and iron in soils. The concentration of cation exchange capacity was significantly (P ≤ 0.05) higher in cowpea treated with Rhizobium as compared to other treatment combinations. The control treatment of mucuna forage greatly improved the concentrations of manganese, boron, copper, molybdenum, and zinc over other treatment combinations only before the flowering stage. However, the concentrations of micronutrients were significantly higher on the treatment combination of lablab and single inoculation of AMF after harvesting. Generally, dual inoculation with AMF and Rhizobia enhanced soil properties when compared to a single inoculation or untreated control

    Feed intake, growth performance and carcass characteristics of Damara lambs fed bush-based rations from four encroacher bush species
    (Tropical Animal Health and Production, 2025) Shiningavamwe, Katrina Lugambo; Lutaaya, Emmanuel; Mupangwa, Johnfisher
    The effect of feeding bush-based finishing rations on the performance of Damara lambs was studied. Thirty weaned lambs weighing 16.7 ± 1.9 kg were allocated to five treatments in a completely randomized design over a 90-day feeding period. The control diet (T1) consisted of Lucerne (10%), grass hay (30%) and concentrate mix (60%). The other diets consisted of roughage (40%) from the milled bushes Senegalia mellifera (T2), Dichrostachys cinerea (T3), Terminalia sericea (T4) and Rhigozum trichotomum (T5) and concentrate mix (60%). At the end of the feeding trial, the lambs were slaughtered and carcass characteristics were evaluated. The average daily feed intake (ADFI) was affected (P < 0.05) by sex, treatment, week and treatment x week interactions. The ADFI for T1 exceeded (P < 0.05) that for T2 and T3, at most time points. The ADFI of T1 and T4 were similar (P > 0.05) at weeks 6 to 10, but differed (P < 0.05) at other time points. The average daily gain (ADG) and feed conversion ratio (FCR) were affected (P < 0.05) by sex and treatment. The ADG (g/day) least squares means (± S.E) for T1 – T5 were 148.0 ± 6.9, 156.4 ± 6.9, 124.2 ± 6.9, 133.7 ± 6.9 and 133.7 ± 6.9, respectively. Treatment T2 had a better (P < 0.05) FCR compared to other bush-based treatments. Males had heavier (P < 0.05) final, hot and cold carcass weights than females. Lambs fed T4 had greater (P < 0.05) rib eye area than T1 (8.3 ± 0.5 vs. 5.9 ± 0.5 mm2). Bush-based diets can serve as production diets for weaned sheep and result into acceptable weight gain and carcass quality

    The evaluation of in vitro repellency and acaricidal efficacy of Aloe ferox and Acokanthera oppositifolia crude extracts against Amblyomma hebraeum ticks
    (Acta Scientific Veterinary Sciences, 2024) Marcia, Sanhokwe; John, Mupangwa; Soul, Washaya
    fluenced the repellency and acaricidal activity against adult engorged female Ambylomma hebraeum ticks. The researchers analyzed the acetone, methanol, and ethanol extracts of both plant species. The experiment followed a completely randomized design with a factor arrangement of 2 (plant species), 3 (organic solvent extraction methods: acetone, methanol, ethanol), and 3 (concentration levels: 15%, 30%, 50%). Distilled water and Dazzel dip (15% and 30%) were employed as negative and positive controls, respectively. Repellency was assessed over a six-hour period, while acaricidal activity was measured over seven days. The results of the study demonstrated that the solvent extracts of Aloe ferox and Acokanthera oppositifolia exhibited a repellent effect ranging from 6% to 89%. Acetone extracts, overall, displayed lower repellency activity compared to methanol and ethanol extracts, with percentages of 58%, 66.5%, and 80.5% for acetone, ethanol, and methanol, respectively. At a concentration of 15% for all solvents, the repellency effect was observed to be 14% for acetone, 9.5% for ethanol, and 11% for methanol. Irrespective of the solvent extraction method used, a higher repellency activity was observed at the 50% concentration level, with statistical significance (P < 0.05). The acaricidal activity of Aloe ferox and Acokanthera oppositifolia significantly increased with the concentration of the extracts. It was concluded that Aloe ferox and Acokanthera oppositifolia plants possess repellent and acaricidal activities, particularly at a 50% concentration for acetone and methanol extracts, respectively. Additionally, Acokanthera oppositifolia demonstrated a higher repellency activity, while Aloe ferox exhibited stronger acaricidal activity

    Evaluation of factors affecting productivity and profitability of Lohmann Brown layers in a semi-arid environment
    (2020) Samkange, Alaster; Kandiwa, Erick; Mushonga, Borden; Amunyela, Selma A.; Bishi, Alec S.; Charamba, Vonai; Mbiri, Pricilla
    A prospective 27-week study investigated the effect of age, ambient temperature, humidity and photoperiod on egg weight and production in Lohmann Brown layers, and thus the profitability of the egg-producing enterprise at a farm in central Namibia, designated Farm A. Overall, age of birds, average temperature, humidity and photoperiod were strongly correlated with mean egg weight (r=0.84, 0.7, -0.51 and 0.7, respectively; p<0.001) but there was a weaker correlation of age, temperature, humidity and photoperiod to the number of eggs/bird (r=0.49, 0.41, -0.43 and 0.34, respectively). Increase in the age of birds, temperature and photoperiod resulted in a significant increase in mean egg weight. A decrease in humidity, however, resulted in a significant increase in mean egg weight. Labour and feed costs contributed 51% and 14%, respectively, to the overall costs of the enterprise. Egg sales contributed the bulk of the income at 88%, which was followed by the sale of spent layers at 12%.The study concluded that Lohmann Brown layers performed well in the semi-arid conditions of central Namibia provided that extreme environmental conditions are avoided. The high input costs, especially labour and feed, were the main constraints to profitability and finding ways to reducing these costs is key to increasing profitability. Increasing the size of the flock is one practical way of offsetting the high labour costs.

    Assessment of normal mortalities, biosecurity and welfare of Lohmann Brown layers at a farm in central Namibia
    (2020) Samkange, Alaster; Mushonga, Borden; Kandiwa, Erick; Kambode, Josephina Ndamonako; Mbiri, Pricilla; Gorejena, Brighton; Madzingira, Oscar
    Objective: The current study investigated the causes of mortality and evaluated the biosecurity situation and welfare conditions of Lohmann Brown layer chickens reared for 12 months, from point-of-lay, at farm A in central Namibia. Materials and Methods: Necropsies, standard biosecurity appraisal and on-farm welfare assessment tools were used. A standard protocol was used for post-mortem examinations of dead birds. The Chi-square test was used for analysis of causes of mortality whilst linear regression was used for analysis of the temporal distribution of mortality. Results: The overall mortality rate throughout the study period was 18.7% (N = 1000). There was a very strong negative correlation between duration of birds in lay and proportion of live birds [r (162) = 0.97, p<0.05]. The proportion of live birds decreased by an average of 2.98% for every 50 days of the laying period. Overall, the proportional mortalities due to undetermined causes (31.6%) were greater than those due to inflammatory conditions, trauma, cannibalism and retained eggs (20.9,19.3,16.6 and 11.8% respectively, p<0.05). Conclusion: The high mortality rates reported in this study have an obvious negative impact on productivity and thus there is a need to improve the biosecurity and welfare conditions for these layers in order to improve profitability.

    African swine fever outbreak at a farm in central Namibia
    (2019) Samkange, Alaster; Mushonga, Borden; Mudimba, Douglas; Chiwome, Bernard; Jago, Mark; Kandiwa, Erick; Bishi, Alec S.; Molini, Umberto
    An outbreak of African swine fever (ASF) occurred at a farm in central Namibia in March 2018. Fourteen pigs died out of a herd of 59 animals over a period of 16 days between the first and sixteenth of March 2018. The clinical signs observed included sternal recumbency, fever, weakness, pain and reluctance to move, hyperemia of the skin and anorexia, followed by death. Necropsy findings included large amounts of unclotted blood in the pleural and peritoneal cavities, diffuse carcass congestion, splenomegaly, consolidation of both lungs, hemorrhagic and frothy airways and trachea, hepatomegaly and congestion, congestion of the gastric mucosa, enlarged and congested kidneys, ecchymotic epicardial, and endocardial hemorrhages, and very enlarged and congested urinary bladder. All the remaining pigs were euthanized, burned, and buried under state veterinary supervision. The authors concluded that the outbreak resulted from indirect transmission of the ASF virus due to lapses in biosecurity measures.

    Demographics, distribution, ownership and naming patterns of pets presented to a mobile clinic for sterilisation in Namibia
    (2020) Baines, Ian John; Baines, Sharon; Mushonga, Borden; Gorejena, Brighton; Mbiri, Pricilla; Samkange, Alaster; Kandiwa, Erick; Madzingira, Oscar
    This study analysed the demographics, spatial distribution, ownership and naming patterns of dogs and cats presented to the University of Namibia’s veterinary mobile clinic for sterilisation from small underserved towns around Namibia. The proportional distribution of pets was determined based on species, sex, age, owner gender, town of origin and naming categories. Overall, 84.4% (n = 2909) of the animals presented for sterilisation were dogs and the remainder were cats (15.6%, n = 539). Of the dogs presented for sterilisation, 51.9% (n = 1509) were male and 48.1% (n = 1400) were female. In cats, 51.4% (n = 277) were male, whilst 48.6% (n = 262) were female. Overall, the majority of pets (68.2%) were presented for sterilisation from urban areas than rural areas (31.8%). About 49.8% of men and 24.2% of women that presented pets for sterilisation came from urban areas, whilst 20.1% of the women and 11.7% of the men that presented pets for sterilisation were from rural areas. Of all the pets presented for sterilisation, the majority were male-owned (64%, n = 2206). Pets were mainly presented for sterilisation at < 2 years (41.1%), 2 to < 4 years (32.4%) and 4 to < 6 years (15.4%). The naming of pets was mainly after people (42.4%), circumstances (20.6%) and appearance (15.5%). This community engagement exercise yielded valuable demographic data indicating that pet origin, sex and species and owner gender were important factors in determining the voluntary presentation of pets for sterilisation in the study area.

    Conception rates and calving intervals of different beef breeds at a farm in the semi-arid region of Namibia
    (2019) Samkange, Alaster; Kandiwa, Erick; Mushonga, Borden; Bishi, Alec S.; Muradzikwa, Erdwin N.; Madzingira, Oscar
    A retrospective study from 2004 to 2017 investigated the effect of bull age, cow age and breed on conception rates, and calving intervals of beef cattle at Neudamm farm, Khomas region, Namibia. Bulls ranging from 4 to 14 years of age were used to breed cows up to 17 years of age. A total of 1804 pregnancies were diagnosed in Afrikaner (81.8%), Nguni (14.1%), and Simmental (4.1%) cows. The overall conception rate of beef cattle during the study period was 71.7 ± 9.5%. The overall conception rate of the Nguni cows (78.3%) was significantly higher than that of the Afrikaner (70.9%) and the Simmental cows (64.9%) (p < 0.05). The age of sires had no effect on overall conception rate in all three breeds (p > 0.05). Afrikaner dams more than 10 years old had the least rate of conception (60.4%, p < 0.05) within that breed category. Nguni dams between four to 10 years had the greatest conception rate (86.5%, p < 0.05). Age of dams had no effect on conception rates in Simmental cattle (p > 0.05). The overall mean length of all calving intervals in the Nguni cows (366 ± 35 days) was significantly shorter than those of the Afrikaner cows (487 ± 62 days) and the Simmental cows (484 ± 110 days) (p < 0.05). The 2013 breeding season produced the highest overall conception rates (~ 85%), and the 2007 breeding season produced the lowest overall conception rate (~ 51%). From a fertility point of view, the Nguni breed seemed best suited for the semi-arid conditions which are prevalent in most of Namibia.

    Bovine rumen impaction caused by ingestion of Gonometa postica cocoons in eastern-central Namibia
    (2019) Samkange, Alaster; Hausiku, Magrecia; Kandiwa, Erick; Mbiri, Pricilla; Muradzikwa, Erdwin N.; Mushonga, Borden
    Cases of rumen impaction caused by ingestion of Gonometa postica cocoons occurred at a farm in eastern-central Namibia. Ten animals died on the farm over the previous 5 months. Rumenotomies were successfully performed on three affected animals. The authors were of the opinion that the affected animals ingested the cocoons around the time of weaning, which then resulted in tangled masses that gradually stretched and enlarged because of entrapment of ingesta, eventually causing impaction of the rumen in the young adult animals. These are the first reported cases of ruminal impaction attributable to G. postica cocoon ingestion in Namibia.

    Assessing the potential of using nylon bags in batch analysis of crude fibre and ether extract of livestock feeds
    (OMICS Group, 2012) Ncube, S.; Mpofu, I.
    The objective of this study was to determine the potential of laboratory batch analysis and optimum number of bags to be used. Katambora, veld hay and maize stover were analyzed for Crude Fibre (CF) and Ether Extract (EE) using the proximate analysis procedure but with samples bagged in nylon bags of pore size 60 micron. A completely randomized block design was used with Treatment 1 as the control, Treatment 2 with 1 bagged sample, Treatment 3 with 2 bagged samples, Treatment 4 with 3 bagged samples and Treatment 5 with 4 bagged samples. Results showed that there is a potential to use nylon bags in CF and EE analysis on katambora, veld hay and maize stover. There was an interaction between block and treatment. EE analysis on Katambora showed no significant difference among all treatments but for maize stover and veld hay, treatment 4 and 5 were significantly different from all the other treatments. In CF analysis trial, treatment 2 and 3 did not differ significantly from the control, while treatment 4 and 5 were significantly different from the control for all the diets. It was concluded that there is a potential to do batch analysis with optimum number varying between forage type and component of analysis. The proposed batch analysis is more sensitive with EE than with CF analysis.

    An assessment of the role of research and extension services for small-scale crop farmers in North-Central Namibia
    (2012) Thomas, Benisiu
    The aim of this study was to assess agricultural research and extension services that are aimed at improving rural household livelihoods in the changing environment in the north-Central Regions of Namibia. The study reviewed various secondary sources or publications and unpublished sources comprising technical reports, books, review papers and maps, all of which were deemed useful based on the role of agricultural research and extension services in north-Central Namibia. The presentations of the results were illustrated by examples from the area of crop production including seed multiplication, animal draught power and crop improvement schemes. The study found sufficient evidence that some research-extension strategies being employed are moderately successful. The main challenge, however, remains to strengthen national farming research or extension systems with an appropriate institutional and coordinating structure, focusing on decentralised participatory and adaptive research and on farm trials.

    Coping with Climate Change Challenges by Feeding Indigenous Chickens under Intensive Systems in Namibia
    (OMICS Group, 2012) Petrus, Ndilokelwa P.; Mpofu, I.; Shikongo-Nambambi, Martha N.
    Floods that have hit Northern Communal Areas (NCAs) of Namibia in recent year pose feeding and other challenges to indigenous chicken. Indigenous chickens constitute a major source of livelihoods among rural farmers. The objective of this study was to determine the potential of intensive feeding of high and low plane of protein nutrition to indigenous chickens as one way of coping with environmental challenges caused by annual floods in the NCAs. Adequacy of protein inclusion in the diet is a viable option for improving the growth of small rural owned chickens. Two hundred and four indigenous chickens were subjected to two levels of plane of nutrition namely high and low plane of protein nutrition. At the low level, the protein was 18% in the 1-8 week age group, 16% in 9-22 week age group and 12% in the 23-36 week age. Feeding at high plane of protein nutrition was as follows; 23% in the 0-8 week age group, 20% in the 9-22 week age group and 16% in the 23-36 week age group. The control group was fed according to the Namibian poultry industry standards. The results showed significant and highest responses between the treatments in weeks 1-8 of age. Between 9-22 weeks, chicken mortality lowest at 5.6% in the high plane of nutrition group compared to 14.4% in the low plane of nutrition. The birds in control group consumed significantly (P<0.05) less feed than those fed with the high and low protein diet. Intensive feeding has a potential of alleviating nutritional stress of indigenous chickens under adverse environmental conditions. Farmers however, have to respond by cropping more intensively for the feed resources to be available.
