| Summary: | 碩士 === 國立臺灣大學 === 畜產學研究所 === 90 === The objective of the present study is to establish an enforced milk replacer feeding regimen for dairy goat kids. Experiment 1 examined the effects of colostrum feeding length（1 vs 3 days）and the difference of milk replacer formula（kid vs calf）on the immunity development of kids before weaning. The results showed that two colostrum feeding length（1 vs 3 days）achieved similar plasma IgG concentration and two milk replacer（kid vs calf）resulted in similar weight gain as natural goat milk. Experiment 2 compared different immunoglobulin G (IgG) sources with the goat colostrum. The results indicated that plasma IgG were the highest in the goat colostrum feeding followed by dairy cow’s colostrum treatment, with the lowest levels in both porcine plasma IgG and colostrum deprivation treatments. Experiment 3 showed that kids offered milk replacer enforced with lactic acid bacteria 1×108 CFU/ mL had higher IgG than control treatment on week 1. In conclusion, a proper feeding regime for dairy goat kids is to feed newborn goat kids immediately with colostrum containing 4-6﹪IgG five times on day 1, followed by feeding milk replacer enforced with lactic acid bacteria 1×108 CFU / mL for week 1. Starter is offered starting on week 2. On weeks 7, 8, 9 and 10, milk replacer was offered at 75, 50, 25, 0﹪of week 6 ad libitum level to gradually wean the kids.
