There is a new way to feed pigs-- feeding distiller's grains to pigs has more nutritional benefits.

The wine trough is a by-product of the wine-making industry, with high yield and large quantity. Many farmers feed it directly after fresh or dried, which is disadvantageous to the growth and weight gain of dried pigs because of the high content of residual alcohol and crude fiber. Feeding pigs after scientific treatment of the wine trough with the following new methods can obviously reduce the cost of raising pigs and improve the efficiency of raising pigs.

1. Drying and feeding

The general water content of fresh distiller's grains is 60%-70%. If it is dried and crushed at 80-100C, it can effectively reduce the content of residual alcohol and improve the palatability of pigs. And can improve the internal quality of pigs, the histone content of Xitao powder can reach 13% Mel 15%, which is equal to the content of white matter in wheat bran group. According to the experiment, the wine trough powder can completely replace 20% of the bran in the diet of thousands of pigs or 40% of the bran in the diet without affecting the growth of pigs.

2. Fermented feeding

With the application of biological fermentation technology, single-cell protein feed can be produced by using living trough, the content of crude protein can reach 20% Mel 40%, and the content of crude fiber is also greatly reduced, which can replace part or all of egg self-made feed in pig feed. The most simple production method is to add 20% to 30% of Midi or sell iron to the sample distiller's grains, the water content should be clustered but not dripping, and then evenly drop the yeast (purchased by he Shou lemon factory) and culture it under the condition of 20-30C. Generally, it can be fermented successfully in 36-48 hours.

III. Silage feeding

Add 0.2% urea to 0.3 end of fresh distiller's grains with a water content of 60% to 704. Silage is carried out according to the main points of the production technology of ordinary straw silage, which can be fed in about 40 days. According to the experiment, 30% of the silage wine cap is added to the fattening diet, and the effect is better.

All right, the above is the new method of feeding lees to pigs brought by the editor of Tuliu.com. Friends who raise pigs at home can go back and have a try. So I'll see you next time.
