【摘要】：本论文通过两个试验研究香甜鲜复合调味剂在仔猪教槽料和保育料中的应用。试验目的,研究香甜复合物和香甜鲜复合物对断奶仔猪生长性能、养分消化率、粪便微生物以及血液生化指标的影响。为香甜鲜复合物在断奶仔猪饲料中的应用提供可靠的依据,促进饲料调味剂在断奶仔猪饲料中的发展。本研究共分为两个试验。试验一为香甜复合物和香甜鲜复合物的偏好性试验。试验选取体况良好、体重为6.91±0.61kg的21日龄断奶仔猪60头。试验随机分为2个处理组,每个处理组6个重复,每个重复5头仔猪。各处理组在断奶前的教槽料中不添加调味剂,其中对照饲料为不添加任何调味剂的基础教槽料,试验饲料分别为基础教槽料+0.8kg/t香甜复合物、基础教槽料+2kg/t香甜鲜复合物。试验期间自由采食,每天交换4次对照饲料和试验饲料的料盆位置,以避免仔猪对料槽位置的记忆影响试验结果。试验周期为5天。结果表明,断奶仔猪对香甜复合物没有偏好,对香甜鲜复合物有中高度偏好。试验二在断奶仔猪教槽料阶段和保育料阶段添加香甜复合物与配合使用香甜鲜复合物和香甜复合物对断奶仔猪生长性能、养分消化率、粪中微生物菌群以及血清生化指标的影响。试验选取体况良好、体重为2.24±0.42kg的21窝7日龄三元仔猪,随机分为3个处理,每个处理7个重复。教槽训练阶段,对照组饲喂不加调味剂的教槽料,试验组A和试验组B分别饲喂基础教槽料+0.8kg/t香甜复合物、基础教槽料+2kgR香甜鲜复合物进行教槽训练。教槽料阶段从每个处理挑选出体况良好、体重为6.11±0.52kg的6个重复,剔除各窝中发育不良的仔猪,每个重复10头仔猪,共180头。对照组饲喂不加调味剂的基础教槽料,试验组A和试验组B分别饲喂基础教槽料+0.8kg/t香甜复合物、基础教槽料+2kh/t香甜鲜复合物。教槽阶段前三天从早上6:30开始,每隔2小时清理和称量剩余饲料,之后添加新的教槽料,直至20:30。保育阶段对照组饲喂不加调味剂的保育料,试验组A和试验组B分别饲喂基础保育料+0.8kgR香甜复合物、基础保育料+0.8kg/t香甜复合物。试验期57 d。结果表明,在教槽料阶段,试验组A和试验组B较对照组相比平均日采食量差异均不显著(P0.05)。试验组A较对照组相比平均日增重差异不显著(P0.05),而试验组B较对照组相比有提高平均日增重的趋势,提高了11.12% (P0.05)。试验组B较对照组相比EE消化率显著提高(P0.05),提高了8.30%。在保育料阶段,试验组A和试验组B较对照组相比平均日增重和平均日采食量差异均不显著(P0.05)。试验组B较对照组相比血液中Leptin的含量显著降低(P0.05),降低了17.38%；血液中Ghrelin的含量显著升高(P0.05),升高了15.69%。试验全程,试验组B的平均日增重较对照组显著提高(P0.05),提高了10.44%。结果表明,香甜鲜复合物和香甜复合物在断奶仔猪教槽阶段和保育阶段配合使用比单独使用香甜复合物效果好。综上所述,添加香甜鲜复合物的教槽料更受断奶仔猪喜爱。香甜鲜复合物在教槽阶段较对照组和香甜复合物组有更好的使用效果。香甜鲜复合物和香甜复合物在断奶仔猪教槽阶段和保育阶段配合使用比单独使用香甜复合物效果好。
[Abstract]:In this paper, two experiments were conducted to study the application of sweet and fresh flavoring agents in piglets' slots and conservation materials. The purpose of this study was to study the effects of sweet and sweet compound and sweet and sweet fresh compound on the growth performance, nutrient digestibility, fecal microorganism and blood biochemical indexes of Weanling Piglets. To provide a reliable basis for promoting the development of feed flavoring in weanling pig feed. This study was divided into two tests. The test was a preference test for sweet and sweet complex and sweet and sweet fresh compound. The experiment selected 60 weanling piglets with good body condition and a weight of 6.91 0.61kg years old. The experiment was randomly divided into 2 treatment groups, each treatment was treated with each treatment. The group had 6 repetitions, each repeated 5 piglets. The treatment group did not add flavoring agent in the slots before weaning. The control feed was the basic teaching material without any flavoring agent. The experimental feed was +0.8kg/t sweet compound of basic teaching grooves and +2kg/t sweet fresh compound in the basic teaching trough. During the test, the feed was free and exchanged 4 per day. The experiment period was 5 days. The results showed that the weanling piglets had no preference to the sweet and sweet complex and had a high preference to the sweet and fresh compound. Test two added sweet compound to the piglet stage and the nursery material stage. The effects of sweet and sweet compound and sweet compound on the growth performance, nutrient digestibility, microbial flora and serum biochemical indexes of weanling piglets were selected. The experiment selected three piglets with good body condition, 21 litter and 7 day old piglets with a weight of 2.24 + 0.42kg, were randomly divided into 3 treatments, each treatment was repeated, the training stage of the teaching trough, the control group The experimental group A and the test group B were fed with +0.8kg/t sweet compound of the basic teaching grooves and the +2kgR sweet and sweet fresh compound of the basic teaching grooves, respectively. The control group was fed with 10 piglets, with a total of 180. The control group was fed with the basic teaching material without seasonings. The test group A and the test group B were fed with the basic teaching grooves +0.8kg/t sweet compound, the basic teaching trough material +2kh/t sweet and fresh compound. The teaching trough starts at 6:30 in the first day from 6:30 in the morning, and the remaining feed is cleared and weighed every 2 hours, and then the new teaching material is added. Until the 20:30. protection stage, the control group was fed with no flavoring material, the experimental group A and the test group B were fed with the basic preservation material +0.8kgR sweet compound and the basic care material +0.8kg/t sweet compound. The test period 57 D. results showed that the average daily feed intake difference of the test group A and the test group B compared with the control group was not significant in the experiment period. (P0.05). Compared with the control group, the average daily gain of A in the experimental group was not significant (P0.05). Compared with the control group, the experimental group B increased the average daily weight gain by 11.12% (P0.05). Compared with the control group, the experimental group B increased the EE digestibility significantly (P0.05), increased 8.30%. in the nursery stage, and the experimental group A and experimental group B compared with the control group. Compared with the average daily gain and average daily feed intake (P0.05), B in the experimental group was significantly lower than the control group (P0.05), decreased by 17.38%, the content of Ghrelin in the blood increased significantly (P0.05), increased the whole course of 15.69%. test, and the average daily gain of B in the experimental group was significantly higher than that of the control group (P0.05), and increased by 1. The results of 0.44%. show that sweet and sweet complex and sweet complex are better than the use of sweet and sweet compound in the stage and conservation stage of weanling piglets. To sum up, the slots added with sweet and fresh compound are more popular with weanling piglets. The sweet and sweet fresh compound is better than the control group and the sweet compound in the teaching slot stage. The use of sweet and fresh compound and sweet compound in the piglets during the slot and conservation stage was better than using sweet complex alone.
