【摘要】：本试验旨在研究香甜鲜复合诱食剂和香甜复合物诱食剂配合使用对仔猪生长性能、血清生化指标、养分表观消化率及粪便微生物数量的影响。选取8窝7日龄的大白仔猪,随机分为2个组,每个组4个重复,2个组分别用基础教槽料(对照组)和添加2 kg/t香甜鲜复合诱食剂的试验教槽料进行教槽训练。21日龄断奶时饲喂3 d粥状料过度(采食量无统计)。然后,分别在2个组中选取28头体重相近、体况良好的24日龄仔猪,每个组4个重复,继续饲喂相应教槽料。仔猪37日龄时更换保育料,对照组仍为基础保育料,试验组在基础保育料基础上添加0.8 kg/t香甜复合诱食剂,直至试验结束。试验期59 d。结果表明:1)经过前期教槽训练,与对照组相比,教槽料中添加香甜鲜复合诱食剂能显著提高断奶仔猪的平均日采食量(P0.10),显著降低血清中胰高血糖素样肽-1的含量(P0.10)。2)在保育阶段,与对照组相比,保育料中添加香甜复合诱食剂能显著提高断奶仔猪的平均日采食量和平均日增重(P0.10)。综合分析,2种复合诱食剂在仔猪教槽料和保育料中配合应用可以提高仔猪的生长性能,对粪便微生物菌群和养分表观消化率没有影响。
[Abstract]:The purpose of this experiment was to study the effects of combination of sweet and fresh compound food attractant and sweet compound food attractant on growth performance, serum biochemical index, apparent nutrient digestibility and fecal microbial quantity of piglets. Eight litters of 7-day-old large white piglets were randomly divided into two groups. Each group was repeated four times, and two groups were fed with the basic teaching trough material (control group) and the experiment of adding 2 kg/t sweet fresh compound food inducer to the teaching trough training. After weaning for 21 days, the porridge was overfed for 3 days (there was no statistic of feed intake). Then, 28 24 day-old piglets with similar body weight and good health were selected from two groups, each group with 4 repeated piglets. When piglets were 37 days old, the control group was still the basic preservative, and the experimental group added 0.8 kg/t sweet compound food attractant until the end of the experiment. The experimental period was 59 days. The results showed that the average daily feed intake (P0.10) of weaned piglets was significantly increased by adding sweet fresh compound food attractant to the teaching trough, and the content of glucagon like peptide 1 (P0.10) in serum was significantly decreased (P0.10) at the stage of conservation, compared with the control group, the results showed that compared with the control group, the average daily feed intake (P0.10) of weaning piglets was significantly increased. Compared with the control group, the average daily intake and average daily gain (P0.10) of weaned piglets were significantly increased by adding sweet compound food attractant to the preservative diet. It was comprehensively analyzed that the application of two kinds of compound trapping agents in the teaching and conservation feed of piglets could improve the growth performance of piglets, and had no effect on faecal microflora and apparent digestibility of nutrients.
