【摘要】：本试验选取胎次、体重相近、健康状况良好的二元母猪(大白×长白)108头,采用单因子试验设计,随机分为6个处理,每个处理18个重复,每个重复1头母猪。处理一为对照组,饲喂基础日粮;处理二至处理六为试验组,分别饲喂添加0.5%、1%、2%、3%、4%酶解毛血肽的日粮。试验从母猪配种后开始,到母猪断奶后再次发情配种结束。研究结果表明:在母猪妊娠期日粮中添加酶解毛血肽后,提高了母猪初乳品质,其中当妊娠期日粮中添加0.5%酶解毛血肽时,初乳的乳蛋白提高了28.55%(P=0.074),非乳脂固体提高了26.76%(P=0.071);母猪产仔性能提高,其中当妊娠期日粮中添加0.5%酶解毛血肽时,初生窝重提高了13.57%(P=0.078);降低了母猪妊娠期血清尿素氮含量,提高了IgG(免疫球蛋白G)含量,其中当日粮中添加1%酶解毛血肽时,血清尿素氮降低了24.29%(P0.05),日粮中添加4%酶解毛血肽时,血清中IgG(免疫球蛋白G)含量提高了26.25%(P=0.159);但对母猪妊娠期各阶段营养物质的消化率无影响。在母猪泌乳期日粮中添加酶解毛血肽后,提高了哺乳仔猪生长性能,其中当泌乳日粮中添加0.5%酶解毛血肽时,断奶窝重提高了13.37%(P0.05),断奶仔猪平均重提高了10.74%(P0.05);但对母猪泌乳期血液生化指标和血清抗体水平、泌乳期营养物质消化率、断奶后发情时间间隔无影响。综合本试验结果,在日粮中添加酶解毛血肽可提高母猪的繁殖性能和增强母猪免疫力、降低血清尿素水平。在母猪日粮中添加0.5%酶解毛血肽时效果最佳。
[Abstract]:In this experiment, 108 sows (big white 脳 long white) with similar birth weight and good health were selected, and were randomly divided into 6 treatments, 18 replicates per treatment, and 1 sows per replica. Treatment 1 was the control group, fed basic diet, and treatment 2 to 6 was the experimental group, which was fed the diet supplemented with 0. 5% and 3% hydrolysate triglyceride, respectively. The experiment began after sow breeding and ended after weaning. The results showed that the quality of porcine colostrum was improved after the addition of enzymatic hemagglutinin to the diet during gestation, especially when 0.5% hemagglutinin was added to the diet during gestation. The milk protein of colostrum increased 28.55% (P0. 074), the solid of non-milk fat increased 26. 76% (P0. 071), the litter performance of sows was improved, and the litter weight increased by 13. 57% (P0. 078) when adding 0.5% enzyme to the diet during pregnancy, and decreased the serum urea nitrogen content of sows during pregnancy. The content of IgG (immunoglobulin G) was increased. The serum urea nitrogen decreased by 24.29% (P0.05) when 1% enzyme hydrolyzed capillary hemopeptide was added to the diet on the same day, and 4% enzyme hydrolyzed hairy blood peptide was added into the diet on the same day, and the serum urea nitrogen decreased by 24.29% (P0.05). The content of IgG (immunoglobulin G) in serum increased by 26.25% (P _ (0.159), but it had no effect on the digestibility of nutrients in different stages of gestation. The growth performance of suckling piglets was improved with the addition of enzyme hydrolyzed hairy blood peptide into the lactation diet, especially when 0.5% enzyme hydrolyzed haemorrhagic peptide was added to the lactating diet. Weaning litter weight increased by 13.37% (P0.05), weaning piglets increased by 10.74% (P0.05), but there was no effect on blood biochemical index and serum antibody level, digestibility of nutrients in lactation period and estrus interval after weaning. According to the results of this experiment, the addition of enzymatic hemopeptide to the diet can improve the reproductive performance of sows, enhance the immunity of sows, and reduce the level of serum urea. The best effect was obtained when 0.5% enzyme was added to the diet of sows.
