微生物制剂在猪场使用效果分析

The Effect Analysis of Using Microbial Preparation at the Pig Farm

为了检验微生物制剂（酵母菌＋酵母培养物＋芽孢杆菌）对妊娠母猪、哺乳母猪、断奶仔猪的使用效果。试验采用了180头胎次和妊娠期相近的基础母猪，随机分为两组：试验组母猪从妊娠第80-87天饲喂含0．25％微生物制剂的全价饲料，从第88天到哺乳仔猪断奶。饲喂含0．5％微生物制剂的全价饲料；对照组母猪按常规饲喂全价配合饲料。将180头母猪所产的1701头健康断奶仔猪。随机分为两组，饲喂35d，试验组和对照组使用的日粮饲料完全一样，试验组添加0．25％微生物制荆。试验结果表明：试验组比对照组健康仔猪数平均提高2．02％；哺乳仔猪断奶重平均提高5．925％；断奶仔猪平均日增重提高6．65％，料肉比平均下降6．05％。

In order to examine the effect of microbial preparation （microbe ＋ nutrientyeast ＋ sporebacteria）on the gravid sow and breast - fed sow and weaner piglet.This experiment adopt 180 basal sow of fetal and similiar the period of gestation,then divided into two groups： The sows of the test group feed full - price forage include 0.25 % microbial preparation, from gestation of 80th day to 87th day, and feed full - price forage include 0.5% microbial preparation from 88th day to the day of weaning piglet;But The sows of the contrast group feed full - price forage as usual .Then divided 1701 healthy weaner piglets which horned by 180 sows into two groups,and feed 35 days,the test group and the contrast group feed the same forage every day, then the test group add 0.25% microbial preparation, At last the experiment result show： The quantities of healthy piglets of the test group increase 2.02 % averagely more than the contrast group;The brood weigh of breast-fed piglet until wean increase 5,925% averagely;and the weight of the weaner piglet increase 6.65 % averagely every day;and the rate of the forage and the meat decrease 6.05 % averagely.
