【摘要】：本論文通過兩個試驗研究香甜鮮復合調(diào)味劑在仔豬教槽料和保育料中的應用。試驗目的,研究香甜復合物和香甜鮮復合物對斷奶仔豬生長性能、養(yǎng)分消化率、糞便微生物以及血液生化指標的影響。為香甜鮮復合物在斷奶仔豬飼料中的應用提供可靠的依據(jù),促進飼料調(diào)味劑在斷奶仔豬飼料中的發(fā)展。本研究共分為兩個試驗。試驗一為香甜復合物和香甜鮮復合物的偏好性試驗。試驗選取體況良好、體重為6.91±0.61kg的21日齡斷奶仔豬60頭。試驗隨機分為2個處理組,每個處理組6個重復,每個重復5頭仔豬。各處理組在斷奶前的教槽料中不添加調(diào)味劑,其中對照飼料為不添加任何調(diào)味劑的基礎(chǔ)教槽料,試驗飼料分別為基礎(chǔ)教槽料+0.8kg/t香甜復合物、基礎(chǔ)教槽料+2kg/t香甜鮮復合物。試驗期間自由采食,每天交換4次對照飼料和試驗飼料的料盆位置,以避免仔豬對料槽位置的記憶影響試驗結(jié)果。試驗周期為5天。結(jié)果表明,斷奶仔豬對香甜復合物沒有偏好,對香甜鮮復合物有中高度偏好。試驗二在斷奶仔豬教槽料階段和保育料階段添加香甜復合物與配合使用香甜鮮復合物和香甜復合物對斷奶仔豬生長性能、養(yǎng)分消化率、糞中微生物菌群以及血清生化指標的影響。試驗選取體況良好、體重為2.24±0.42kg的21窩7日齡三元仔豬,隨機分為3個處理,每個處理7個重復。教槽訓練階段,對照組飼喂不加調(diào)味劑的教槽料,試驗組A和試驗組B分別飼喂基礎(chǔ)教槽料+0.8kg/t香甜復合物、基礎(chǔ)教槽料+2kgR香甜鮮復合物進行教槽訓練。教槽料階段從每個處理挑選出體況良好、體重為6.11±0.52kg的6個重復,剔除各窩中發(fā)育不良的仔豬,每個重復10頭仔豬,共180頭。對照組飼喂不加調(diào)味劑的基礎(chǔ)教槽料,試驗組A和試驗組B分別飼喂基礎(chǔ)教槽料+0.8kg/t香甜復合物、基礎(chǔ)教槽料+2kh/t香甜鮮復合物。教槽階段前三天從早上6:30開始,每隔2小時清理和稱量剩余飼料,之后添加新的教槽料,直至20:30。保育階段對照組飼喂不加調(diào)味劑的保育料,試驗組A和試驗組B分別飼喂基礎(chǔ)保育料+0.8kgR香甜復合物、基礎(chǔ)保育料+0.8kg/t香甜復合物。試驗期57 d。結(jié)果表明,在教槽料階段,試驗組A和試驗組B較對照組相比平均日采食量差異均不顯著(P0.05)。試驗組A較對照組相比平均日增重差異不顯著(P0.05),而試驗組B較對照組相比有提高平均日增重的趨勢,提高了11.12% (P0.05)。試驗組B較對照組相比EE消化率顯著提高(P0.05),提高了8.30%。在保育料階段,試驗組A和試驗組B較對照組相比平均日增重和平均日采食量差異均不顯著(P0.05)。試驗組B較對照組相比血液中Leptin的含量顯著降低(P0.05),降低了17.38%；血液中Ghrelin的含量顯著升高(P0.05),升高了15.69%。試驗全程,試驗組B的平均日增重較對照組顯著提高(P0.05),提高了10.44%。結(jié)果表明,香甜鮮復合物和香甜復合物在斷奶仔豬教槽階段和保育階段配合使用比單獨使用香甜復合物效果好。綜上所述,添加香甜鮮復合物的教槽料更受斷奶仔豬喜愛。香甜鮮復合物在教槽階段較對照組和香甜復合物組有更好的使用效果。香甜鮮復合物和香甜復合物在斷奶仔豬教槽階段和保育階段配合使用比單獨使用香甜復合物效果好。
[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.
