Impact of Lactation Stage on the Body Condition and Milk Quality of Black Goat

A total of nineteen black does were used in this study to investigate the impact of lactation stage on body condition, blood metabolism and milk composition. Body condition was assessed together with blood and milk samples, which were collected at week 6 (early), 14 (mid) and 22 (late) of lactation. Body condition score of each doe was also assessed. The overall mean of body condition score was 2.35±0.08 and serum total protein, glucose, triglyceride averaged, respectively 5.80±0.10 g/dl, 120.87±5.34 mg/dl, 51.04±5.38 mg/dl, and milk fat, protein, lactose, solid non fat and total solid percentages averaged 3.24±0.15, 4.49±0.10, 4.44±0.01, 9.71±0.11, and 12.95±0.20, respectively. Body condition at kidding decreased significantly at week 4 and then increased significantly (p<0.05) during mid and late part of lactation. Lactation stage also significantly affected (p<0.05) all milk constituents, and glucose.
