Abstract

Indigenous poultry plays a crucial role in meeting protein needs due to his accessibility, price and ease breeding methodologies. Productive and reproductive performance of available breeds of indigenous poultry in South Africa was analysed using structured survey system, there are basically four phenotypically distinquished breeds: Naked Neck, Ovambo, Potchefstroom Koekoek and Venda. To achieve this, six different villages were used for this study from July, 2017 to June 2018 (12 months). Data observed were, Average age at production, Clutch per year (CPY), Duration of rearing (DR), egg laying length (EGL), Egg per clutch (EGC), Egg per year (EPY), hatchability (HATCH), mortality, Natural Brooding Period (NBP), Natural Incubating Period (NIP), Recovery Period (RP) and survivability at 10-12 weeks (SURV) from Seven thousand, five hundred and thirty eight (7538) indigenous chicken. Four phenotypically distinguished breeds were sampled with respective frequency Naked Neck (864), Potchefstroom Koekoek (2088), Ovambo (1838) and Venda breeds (2748) respectively. Potchefstroom Koekoek is observed to be a good egg producing breed with 15.11±0.25 eggs per clutch. Venda breed possess good mothering ability (hatchability) and high survivability with 86.03±0.31days and 82.70±0.26 days respectively. Naked Neck is known to be more prone to diseases with least (survivability) 60.08±0.25 days. Village was positively correlated with EGC and HATCH, EGY and SURV at p≤0.01 and p≤0.05 respectively. Rearing system was positively correlated with EGC. Rearing system was positively correlated at p≤0.05 on EGC than CPY, HATCH, EGY and SURV. Breed and village interactions were significant at p≤0.05 on RP, AA, DR, EGL, NBP and NIP. Therefore, productive and reproductive traits of indigenous chicken differ across different rearing systems, breeds and villages
