摘要

目的

研究微生态制剂（乳酸菌、枯草芽孢杆菌、酿酒酵母等）对哺乳母猪繁殖性能和发情性能的影响，以提高规模猪场的经济效益。

方法

以某规模猪场的健康哺乳母猪为研究对象，哺乳母猪的年龄、胎次基本一致（3~6胎为主，年龄2~4岁

体重200~260 kg）、健康状况良好、预产期相近的母猪共计2 160头

采用分组对照设计，试验组饲喂添加微生态制剂的哺乳母猪料，对照组饲喂常规哺乳母猪料，试验周期为2025年8月，全程记录并分析母猪的产仔性能、仔猪生长相关指标及母猪产后发情和生产效率。

结果

试验组产房仔猪死亡率（8.03%）显著低于对照组（10.14%）；试验组22日龄仔猪个体均重（5.84 kg）、22日龄成活率（94.64%）均高于对照组（5.58 kg、93.11%）；试验组经产母猪、初产母猪断奶7 d发情率分别为77.2%、87.23%，均高于对照组（分别为76.88%、71.33%），且初产母猪发情率提升效果显著；试验组WSI（断奶至配种间隔）为2.77，显著低于对照组（9.7）。

结论

在哺乳母猪日粮中适量添加微生态制剂，可有效降低仔猪死亡率，提升仔猪生长性能，改善母猪发情周期，减少断奶至配种间隔。

Abstract

Objectives

The effects of a microecological preparation containing lactic acid bacteria

Bacillus subtilis

Saccharomyces cerevisiae

and other strains on the reproduction performance and estrous performance of lactating sows were studied to provide a theoretical basis for increasing the economic benefits of large-scale pig farms.

Methods

2 160 lactating sows with similar age and parity (mainly 3-6 fetuses

age 2-4 years

weight 200-260 kg)

good health status

and similar expected date of childbirth from a large-scale pig farm were divided into the experimental group fed with the daily diet of lactating sows supplemented with a microbial ecological preparation and the control group fed with conventional feed for lactating sow. The experimental period was from August

2025. The reproduction performance of sows

indexes related with the growth of piglets

the postpartum estrus and production efficiency of sows were recorded and analyzed throughout the entire process of experiment.

Results

The mortality rate of piglets in the farrowing house in the experimental group (8.03%) was significantly lower than that in the control group (10.14%). The average body weight of piglets and the survival rate at 22 days of age in the experimental group was 5.84 kg and 94.64%

higher than that in the control group (5.58 kg and 93.11%). The estrus rate of multiparous sows and primiparous sows at 7 days after weaning in the experimental group was 77.2% and 87.23%

higher than that in the control group (76.88% and 71.33%)

with a significant improvement observed in the estrus rate of primiparous sows particularly. The WSI (Weaning to Service Interval) in the experimental group was 2.77

significantly lower than that in the control group (9.7).

Conclusions

Adding a microecological preparation to the daily diet of lactating sows can effectively reduce the mortality rate of piglets

enhance the growth performance of piglet

improve the estrus performance of lactating sows

and reduce WSI.
