Abstract
This study was conducted to evaluate the yield and quality parameters of milk from 60 indigenous South African goats of different genotypes namely Nguni, Boer and Non- descript reared under a free ranging system. Milk yield and quality parameters (milk fat, protein, lactose, solid non-fat and minerals) from Nguni (10), Boer (10) and Non-descript (10) goats was measured and analysed per week at each stage of lactation. Result showed that, Nguni goats produced (1.2±0.09, 1.3±0.11 and 1.2±0.07 litres per day) more milk (P ˂ 0.05) at early, mid and late stages of lactation than Boer (0.6±0.10, 1.0±0.17 and 0.6±0.09 litres per day) and Non-descript (0.3±0.10, 0.3±0.12 and 0.3±0.09 litres per day) goats, respectively. The mean value of milk fat, protein and lactose content from Nguni goat was (3.98, 3.54 and 5.31); Boer goat (2.9, 3.59 and 5.04) and Non-descript goat (4.05, 3.39 and 5.02), respectively. There was significant effect (P ˂ 0.05) of genotypes on milk fat, milk magnesium and sodium contents of Nguni, Boer and Non-descript goats. It could be concluded that, Nguni goat produced more milk than Boer and Non-descript goats, but the Non-descript goat had higher mean percentage of milk fat compared to Nguni and Boer goats.
