摘要
粟糠中含有丰富的纤维素和半纤维素,是一种产量较大的可再生利用资源,是重要的膳食纤维来源,但是粟糠在母猪上的应用报道很少。为研究粟糠对妊娠母猪前期的行为、血清生化指标及生殖激素的影响,试验选用32头胎次、配种时间及体况均相近的"大×长"二元母猪,采用单因子完全随机设计,分对照组、试验Ⅰ组、试验Ⅱ组和试验Ⅲ组,每组8个重复,限位栏饲养,粟糠的添加水平分别为:0%、9%、17%和24.5%,每组的消化能和粗蛋白质基本一致。结果表明:(1)日粮添加粟糠降低了妊娠母猪前期咬栏行为(P<0.05)、舔地行为和站立时间(P<0.01),增加趴卧时间(P<0.05)。(2)降低血清总胆固醇含量(P<0.01)、雌二醇含量(P<0.05),增加孕激素含量(P<0.01)。本试验研究表明妊娠母猪前期日粮中添加粟糠增加了母猪的趴卧休息时间,降低了咬栏、添地等刻板行为,降低血清总胆固醇含量和雌二醇含量,提高了孕激素含量,有利用母猪孕期的子宫内膜增生,受精卵植入,并降低子宫肌肉兴奋度,保证孕期安全。
Millet bran is rich in cellulose and hemicellulose. It is a large-scale renewable resource and an important source of dietary fiber. However, the application of corn bran in sows is rarely reported. In order to study the effects of millet bran on the behavior of pregnant sows, serum biochemical indexes and reproductive hormones, a total of 32 Yorkshire-Landrace sows with similar breeding time and body conditions were randomly divided into control group, experimental group I, experimental group ]l and experimental group i, with 8 replicates in each group,limiting bar feeding. Millet bran adding lev- el was 0%, 9%, 17% and 24.5%, each of the digestible energy and crude protein are basically the same. The results showed as follows：① dietary millet bran decreased the biting behavior （P〈0.05）, licking be- havior and standing time （P〈0.01）, and increased the lying time （P〈0.05） in the early stage of pregnan- cy. ② decrease serum total cholesterol （P〈0.01）, estradiol content （P〈0.05）, increase progesterone con- tent （P〈0.01）. The experiment research shows that millet bran diets in early pregnancy sows increased sows lying rest time, reduce the bite bar, increased the stereotyped behavior, reduce serum cholesterol levels and estradiol levels, increased progesterone content,was useful for endometrial hyperplasia, im- plantation of a fertilized egg, and lower uterus muscle excitability, ensure the safety of pregnancy.
