Embodiment 1

[0036] Embodiment 1. A method of using 2% yeast-fermented distiller's grains to replace 1.3% corn + 0.7% soybean meal in the same amount to make feed for sows in late pregnancy and lactation:

[0037] That is, the formula of the post-pregnancy / lactating sow ration improved after the present invention is:

[0038] 2% yeast fermented distiller's grains, 53.8% corn, 20% dehulled soybean meal, 5% soybean hulls, 10% wheat, 3% fish meal, 0.2% stone powder, 2% soybean oil, 4% pre The materials are mixed, put into a blender, and fully stirred to obtain feed for sows in late pregnancy and lactation period with a content of 2% yeast-fermented distiller's grains.

Embodiment 2

[0039] Example 2 A method of using 4% yeast-fermented distiller's grains to replace 1% corn + 1% soybean meal + 2% soybean hulls in the same amount to make feed for sows in late pregnancy and lactation

[0040] That is, the formula of the post-pregnancy / lactating sow ration improved after the present invention is:

[0041] 4% of yeast-fermented distiller's grains, 54.1% of corn, 19.7% of dehulled soybean meal, 3% of soybean hulls, 10% of wheat, 3% of fish meal, 0.2% of stone powder, 2% of soybean oil, 4% of The materials are mixed, put into a blender, and fully stirred to obtain feed for sows in late pregnancy and lactating period with a content of 4% yeast-fermented distiller's grains.

Embodiment 3

[0042] Example 3 A method of using 4% yeast-fermented distiller's grains to replace 1.5% corn + 1% soybean meal + 1.5% bran in the same amount to make feed for sows in the early pregnancy, late pregnancy and lactation period

[0043] That is, the formula of the feed for sows in the first trimester of pregnancy after the improvement of the present invention is:

[0044] 4% of yeast-fermented distiller's grains, 59.5% of corn, 12.8% of soybean meal, 5% of puffed soybeans, 14.7% of bran, and 4% of premix are put into a mixer and fully stirred to obtain yeast-fermented distiller's grains 4% pre-gestation sow feed.

[0045] The formula of the post-pregnancy / lactating sow feed improved after the present invention is:

[0046] 4% of yeast-fermented distiller's grains, 63% of corn, 10.5% of soybean meal, 12% of puffed soybean, 3.5% of bran, 3% of fish meal, and 4% of premix are put into the mixer and fully stirred, that is Feeds for late pregnancy and lactating sows with a content o...

Abstract

The present invention discloses a sow reproduction and lactation performances improving method by using yeast fermented distillers' grains. Parts of corns and soybean meal or parts of corns, soybean meal and bean curd products in the sow daily feed in the late gestation / lactation periods are replaced by the fermented distillers' grains. The replacing amount of the fermented distillers' grains is 2%-4% of the total amount of the sow daily feed in the late gestation / lactation periods. Or parts of corns, soybean meal and wheat bran in the breeding sow daily feed are replaced by the fermented distillers' grains and the replacing amount of the fermented distillers' grains is 4% of the total weight of the breeding sow daily feed. The percentages are percentages by weight.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a method for improving reproductive performance and lactation performance of sows by using yeast to ferment distiller's grains. Background technique [0002] At present, the productivity level of sows in my country is relatively low, and each sow in large-scale pig farms in my country can provide only about 15-18 weaned piglets per year, while in 2008, developed countries such as the United States have reached 20-25 piglets. The main factors that cause the low productivity of sows in my country are severe constipation, insufficient milk, low feeding and management, and diseases. Among them, the problems of constipation in late pregnancy and insufficient milk during lactation have attracted more and more attention. In my country's intensive scale pig farms, due to the lack of exercise, feeding stress and physiological stress of sows in the late pregnancy, the incid...
