Production performance and physiological responses of Angora goat kids fed acidified milk replacer

Journal of Dairy Science 75:1643-1650. 1992.

Angora kids were blocked by birth weight and sex and assigned randomly to goat milk or acidified milk replacer. Daily milk intake, weekly BW, and heart girth measurements, and blood parameters (packed cell volume, total protein, glucose, and NEFA) were monitored at 3 d (initial) and at 4, 6, 8, and 9 wk of age. Both groups were fed their respective milks for ad libitum intake for 6 wk and then reduced to 75, 50, 25, and 0% of wk-6 intake during wk 7, 8, 9, and 10, respectively. Solid feed (20% CP and 3.1 Mcal of metabolizable energy/kg of DM) was provided for ad libitum intake starting on wk 3. Pretreatment BW (average 2.4 kg) and blood parameters were similar for milk and replacer groups. Packed cell volume (21.8 and 34.2%), total protein (50.3 and 46.6 g/L), and NEFA (0.52 and 0.69 meq/L) for goat milk and acidified milk replacer groups, respectively, were affected by dietary treatment. Final BW (average 10.5 kg) and mean plasma glucose concentration (84 to 88 mg/dL) were similar between treatments; however, kids fed goat milk produced more mohair (13.8%) than those fed acidified milk replacer. Despite physiological differences, acidified milk replacer can be used successfully to raise Angora kids.
