【摘要】：试验旨在研究日粮中添加不同水平姜黄素对断奶仔猪生产性能、养分消化率和血液生理生化指标的影响。选用375头28日龄断奶的"杜×长×大"三元杂交仔猪,按体重相近原则,随机分为5个组,每个组3个重复,每个重复25头,分别饲喂基础日粮(对照组)以及在基础日粮中分别添加100、200、300、400mg/kg姜黄素的日粮,试验期28d。结果表明,与对照组相比:(1)日粮添加100、200、300、400 mg/kg姜黄素分别提高断奶仔猪平均日增重9.38%(P0.05)、14.67%(P0.05)、13.59%(P0.05)、10.51%(P0.05);分别提高断奶仔猪平均日采食量8.26%、12.38%、8.22%、12.73%,均差异显著(P0.05);添加不同水平姜黄素对断奶仔猪的料重比无显著影响(P0.05)。(2)添加100、200、400mg/kg姜黄素分别提高断奶仔猪粗蛋白表观消化率0.50%(P0.05)、2.30%(P0.05)、4.19%(P0.05);添加100、200、300、400mg/kg姜黄素分别提高断奶仔猪粗脂肪表观消化率7.18%(P0.05)、9.29%(P0.05)、5.52%(P0.05)、15.10%(P0.05);添加不同水平姜黄素对断奶仔猪干物质、粗灰分和有机物的表观消化率无显著影响(P0.05)。(3)添加200、300、400mg/kg姜黄素分别降低断奶仔猪血清总胆固醇含量11.38%(P0.05)、9.31%(P0.05)、7.59%(P0.05);添加100、200、300mg/kg姜黄素分别降低断奶仔猪血清甘油三酯含量16.00%(P0.05)、28.00%(P0.05)、4.00%(P0.05);添加100、200、300、400mg/kg姜黄素均可降低断奶仔猪血清中低密度脂密度脂蛋白的含量,分别降低3.16%(P0.05)、12.63%(P0.05)、16.84%(P0.05)、5.26%(P0.05)。(4)日粮添加不同水平姜黄素均可降低断奶仔猪血清AST和ALT的含量,但差异不显著(P0.05)。(5)日粮添加300、400mg/kg姜黄素均显著降低断奶仔猪血清MDA水平(P0.05),分别降低25.27%、19.05%。本试验结果提示,日粮添加姜黄素可提高断奶仔猪生产性能、养分表观消化率,调节血脂代谢,改善肝脏功能,降低脂质过氧化水平,其中以200mg/kg的姜黄素效果为佳。
[Abstract]:The purpose of the experiment was to study the effects of different levels of curcumin on the performance, nutrient digestibility and blood physiological and biochemical indexes of weaned piglets. 375 28 day weaned "du 脳 long 脳 big" three-way crossbred piglets were randomly divided into 5 groups according to the principle of similar body weight, with 3 replicates in each group and 25 piglets per replica. The basal diet (control group) and the basal diet supplemented with 100200300400mg/kg curcumin were fed for 28 days. The results show that Compared with the control group, the average daily gain of weaned piglets increased by 100200300400 mg/kg curcumin supplementation, respectively. The average daily gain of weaned piglets was increased by 9.38 g / g P0.05 and 14.67g / kg respectively. The average daily feed intake of weaned piglets was increased by 8.2612.388.220.22 / 12.735.There was no significant difference between weaned piglets with different levels of curcumin added to weaning piglets. There was no significant difference in feed weight ratio between weaned piglets with different levels of curcumin. The apparent digestibility of crude protein of weaned piglets was significantly increased by adding 100200400mg/kg curcumin, respectively. The apparent digestibility of crude protein in weaned piglets was increased by adding 100200300400mg/kg curcumin, respectively, and the dry matter of weaned piglets was increased by adding curcumin at different levels. The apparent digestibility of crude ash and organic matter had no significant effect on the apparent digestibility of crude ash and organic matter.) addition of 200300400mg/kg curcumin decreased serum total cholesterol content of weaned piglets by 11.38, P 0.05, P 0.031, P 0.05, P 0.05, and P0.05, respectively; addition of 100200300mg/kg curcumin decreased serum triglyceride content of weaned piglets by 16.00, P0.05 and 28.00; added 100200300400mg/kg curcumin, added curcumin, respectively, decreased serum triglyceride content of weaned piglets, and added 100200300400mg/kg curcumin. Low density lipoprotein (LDL-C) in serum of weaned piglets could be decreased. The contents of serum AST and ALT in weaned piglets were decreased by adding curcumin at different levels respectively (P 0.05, P 0.05, P 0.05, 12.63, P 0.05, P 0.05, P 0.05, P 0.05 and P 0.05, respectively). However, there was no significant difference in the content of serum AST and ALT in weaned piglets with different levels of curcumin. The dietary addition of 300400mg/kg curcumin significantly decreased the serum MDA level of weaned piglets and decreased the serum MDA level of weaned piglets by 25.275.05 and 25.277.05, respectively. The results suggested that dietary curcumin supplementation could improve the performance, apparent digestibility of nutrients, regulate lipid metabolism, improve liver function and decrease lipid peroxidation level in weaning piglets, especially curcumin of 200mg/kg.
