东营某规模猪场仔猪的初乳管理试验

在现代规模化猪场中,高产母猪每胎所产仔猪数往往超过其有效哺乳头数目,而初乳对于新生仔猪来说又非常重要,仔猪能否及时吃上初乳决定着仔猪能否健康生长,因此做好仔猪的初乳管理尤为重要。文章做了人工灌服初乳和仔猪随机获取初乳的对比试验。试验结果表明进行初乳管理对于提高仔猪的断奶重,降低仔猪死亡率以及增加仔猪体内的抗体等方面都具有实际意义。初乳管理可使所有新生仔猪均可得到足够的初乳,增加仔猪断奶重量,提高仔猪福利水平。

Colostrum management experiment of piglets in a Dongying scale pig farms

In modern scale pig farms, the number of piglets per litter produced by high-yielding sows often exceeds the number of eff ective suckling nipples, resulting in some piglets not being able to eat breast milk. Colostrum is very important for neonatal piglets, and whether colostrum can be eaten in time determines the survival of piglets, so it is very important to colostrum management. In this paper, the author carried out a comparative experiment of artifi cial feeding colostrum of piglets and random sucking colostrum of piglets. The results showed that the total weaning weight of piglets that artifi cially fed colostrum increased by 0.43 kg compared with that of random sucking colostrum. The total number of piglets in the experiment was 20, and 10 of them were fed colostrum (100 ml) by hand within 6 h of birth and 10 were randomly sucking colostrum in the experiment. This indicates that colostrum management can increase weaning weight of piglets, which is of practical signifi cance in reducing mortality and increasing antibody in vivo. Colostrum management allows all neonatal piglets to get enough colostrum, increase weaning weight and improve their welfare level.
