Abstract
The evaluation of udder measurement and milk composition of two breeds of goat were assessed. A total of one hundred and sixty goat were used for the study comprising of (80 Red Sokoto and 80 white Borno (does). Matured does were used, age ranges between 2-5 years of age and with average body weight of 20 – 35 kg. The udder characteristics were measured using flexible tape, venire caliper, and weight balance. The udder characteristics of each doe was measured postpartum and also during pregnancy. The body weight, udder and teat characteristics measurement were recorded include; Udder length (UL), Udder width (UW), Udder circumference (UC), and Udder volume (UV). Teat traits included Teat length (TL), Teat width (TW), Distance between teats (DBT), Teat to flow distance (TFD). Milk samples were analyzed for total solids % (TS), crude protein % (CP), butterfat %, solids-non-fat % (SNF), ash % and lactose %. All data generated were subjected to analysis of variance using SAS package version. The variation of milk composition of two breed of goats observed that breads have a significant difference on crude protein % (p < 0.05) with higher value in Red Sokoto goat (4.02 ± 0.04%) followed by Borno white (3.64 ± 0.10%). The breed differences may be due to genetic variation, environmental differences and management practices. It was observed that there was significant difference (P<0.01) in the values of udder length, udder width, udder Circumference and udder volume of the two breeds, with higher value in Red Sokoto as compare to Borno white with corresponding values of (12.32 0.32 cm , 12.09 3.82 and 3.48 ) (10.58 0.16, 10.56 0.12, 3.48 and 1.25 0.54) respectively . Physiological variation of udder and teat measurement of two breed of goat observed that the body weight of pregnant red sokoto was higher than lactating red sokoto with the value of 26.07 0.85 kg and 22.33 1.55 kg , different trend were observed in Borno white pregnant and lactating does.
