摘要：

旨在考察自主研制的功能性复合添加剂添加到饮水中对断奶仔猪生长性能、养分消化率和血液指标的影响。试验选取32头初始体重为（7.08±0.47） kg的21日龄断奶健康的"杜×长×大"三元杂交仔猪，按体重相近的原则，随机分为2个处理，每个处理16个重复，饲喂相同的饲粮，分别给予普通的水（对照组）和添加了功能性复合添加剂的水（添加剂组），添加剂与饮水比例为1 g：4 L。试验期14 d。结果表明：1）饮水中添加功能性复合添加剂显著降低仔猪第8~14天的料重比（P<0.05），有降低仔猪第1~14天料重比的趋势（P=0.07）；2）饮水中添加功能性复合添加剂显著提高仔猪对饲粮中粗蛋白质、粗灰分和钙的消化率（P<0.05）；3）饮水中添加功能性复合添加剂显著降低了仔猪血清中尿素氮、甘油三酯、白介素-6和白介素-1的含量（P<0.05）。综上表明，饮水中添加功能性复合添加剂有提高断奶仔猪生长性能的趋势，这可能与其改善仔猪营养物质的消化利用和仔猪免疫状态有关。

Abstract:

The aim of this experiment was to study the effects of the self-developed functional compound additive on the growth performance, nutrient digestibility and blood parameters of weaned piglets. According to the initial body weight, thirty-two Duroc×Landrace×Yorkshire piglets weaned at 21 days of age with an initial body weight of (7.08±0.47) kg were randomly divided into two groups (n=16/group) gave ordinary water (control group) and water added functional compound additive (additive group, additive:water was 1 g:4 L), respectively for 14 days. The results showed that:1) Supplementing the functional compound additive in the drinking water significantly reduced the F/G in 8-14 days (P <0.05), tended to decrease F/G in 1-14 days (P=0.07). 2) Supplementing the functional compound additive in the drinking water significantly increased the digestibility of crude protein, calcium and ash (P <0.05). 3) Supplementing the functional compound additive in the drinking water significantly reduced urea nitrogen, interleukin 6, interleukin 1 and triglycerides levels in serum on day 14 (P <0.05). These results suggest that supplementing the functional compound additive in the drinking water tend to increase growth performance via improving nutrient digestion and utilization, and adjusting immune status of piglets.
