摘要: 本试验旨在研究日粮中添加不同比例的玉米胚芽粕对育肥猪的利用价值。选用45日龄体重(17±2.1) kg健康的商品代PIC猪120头,采用单因子完全随机试验设计,分为4个组,每组5个重复,每个重复6头猪(公、母各半),分别在日粮中添加不同比例的玉米胚芽粕,依次为:0(对照组)、5%(试验1组)、10%(试验2组)、15%(试验3组),各组主要营养指标相同,测定不同水平玉米胚芽粕日粮对育肥猪生产性能、血清中主要生化指标和营养物质表观消化率的影响。结果表明,与对照组相比,试验1组对料重比无显著影响(P>0.05),试验2组显著降低料重比(P<0.05),试验3组显著提高料重比(P<0.05),各组育肥猪的平均日采食量均显著高于对照组(P<0.05),但各试验组之间差异均不显著(P>0.05),且随玉米胚芽粕添加量的增加而略有提高;试验1、2组均有降低血清尿素氮含量的趋势,且试验2组差异显著(P<0.05),而试验3组却显著提高了血清尿素氮含量(P<0.05),各组的血清白蛋白、总蛋白和葡萄糖的含量均无显著差异(P>0.05);与对照组相比,试验1组粗蛋白质和粗纤维的表观消化率均无显著差异(P>0.05),试验2组则显著提高了粗蛋白质和粗纤维的表观消化率(P<0.05),而试验3组却显著降低了粗蛋白质和粗纤维的表观消化率(P<0.05),各组的粗脂肪、粗灰分的表观消化率均无显著差异(P>0.05)。提示,在育肥猪日粮中添加10%玉米胚芽粕对其生产性能、血清生化指标及营养物质表观消化率的改善有利,玉米胚芽粕中抗营养因子可能是纤维素。

Abstract: This experiment was to study the effects of corn germ meal in different levels on use value of finishing pigs.120 health PIC piglets aged 45 days with similar body weight (17±2.1)kg were randomly divided into 4 groups of 5 replicates for each group and 6 pigs for each replicates (male and female were the same in each replicate).Control group was fed basic diet,group one to three were fed diets containing different amounts of corn germ meal (5%,10% and 15%) with the same concentration of the main nutrient items.The results showed that compared with the control group,feed conversion rate in group one was no significant difference (P>0.05),feed conversion rate in group two had a significantly decreased (P<0.05),feed conversion rate in group three was significantly increased (P<0.05),average daily feed intake in control group was significantly lower than that in other groups (P<0.05),and there were no significant differences in daily feed intake among experimental groups (P>0.05).With the corn germ meal level increasing,the daily feed intake was increased slightly.Group one and group two had a tendency to reduce the serum urea nitrogen content,but group two had a significant difference (P<0.05),the content of serum urea nitrogen in group three was increased significantly (P<0.05),there were no significant differences in serum albumin,total protein and glucose levels among all groups (P>0.05). Compared with the control group,the apparent digestibility of crude protein and crude fiber in group one had no significant differences (P>0.05).The apparent digestibility of crude protein and crude fiber in group two increased significantly (P<0.05),and the apparent digestibility of crude protein and crude fiber in group three decreased significantly (P<0.05).There were no significant differences in the apparent digestibility of crude fat and crude ash compared with the control group (P>0.05).Theses results indicate that the best supplementation level of corn germ meal was 10%,the anti-nutritional factors of corn germ meal may be the cellulose.
