Opportunity of Use of Colostrum of Cow as a Passive Immune Resource and Growth Factor to Reduce Death Rate and Increase Growth Rate of Piglets after Weaning

The provision of bovine colostrum significantly increased the weight at weaning (28 days) of piglets (p <0.05), with the highest body weight in piglets receiving an additional 9 ml/bovine colostrum of 8.4 kg at age of 28 days with additional weight of 7.0 kg.The rates of morbidity and mortality during pre-weaning decreased by the increase in dosage of bovine colostrum. The mortality incontrolwas 20.8% (control), P1 12.5% (3 ml / head), P2 8.3% (6 ml / head) and P3 without mortality. The weaning body weight in the treatment groups were 5.8, 6.6, 7.6 and 8.4 kg, respectively. Similarly, the weight gain in the different treatment groups were 4.4, 5.1, 6.2 and 7.0 kg, respectively. The length of intestine were 5.1, 7.5, 10.3 and 11.4 (m), respectively. The corresponding weight of the intestine in the treatment groups were 295.8, 331.0, 398.6 and 434.6 (g), respectively. The length of the colon in the treatment groups were 1.89, 1.90, 1.97 and 2.04 (m), respectively. The length of the villi of small intestine in the treatment groups were 290.1, 306.4, 365.1 and 596.1 (µ), respectively. The corresponding depth of the cryps in the treatment groups were 101.6, 197.8, 46.7 and 171.0 (µ), respectively. The mucosal thickness of large intestine in the treatment groups were 90.8, 68.84, 103.7 and 72.48 (µ), respectively. Key words: Bovine colostrum, piglet performance
