I. Feed formula for raising pigs with distiller's grains

1. The pig weighs 10-20 kg.

Distiller's grains 50% + corn 10% + wheat bran 10% (peanut cake or soybean cake 5%) + straw powder 20% + pine needle powder 6% + bone meal and fish meal 1 jin + calcium superphosphate 1% + methionine 0.05% + lysine 0.15% + salt 0.7% + growth promoter 0.1% + oxytetracycline 20 tablets + biochemical enzyme 0.3%.

2. The pig weighs 20-35 kg.

Distiller's grains 60% + cassava powder (or corn meal) 5% + straw powder 20% + wheat bran 10.7% + pine needle powder 6% + bone powder 1 jin + calcium superphosphate 1% + salt 0.7% + lysine 0.15% + methionine 0.15% + methionine 0.05% + growth promoter 0.1% + peanut cake 1% + oxytetracycline 20 bottle slices + biochemical enzyme 0.3%.

3. Pigs weigh 35-60 kg

Distiller's grains 60% + corn 5% + straw powder 20% + wheat bran 5% + pine needle powder 5.7% + calcium superphosphate 1% + salt 0.7% + lysine 0.15% + growth promoter 0.1% + peanut cake 2% + enzyme 0.20% + oxytetracycline tablets.

4. Pig weight 60-90 kg

Distiller's grains 50% + rice (or corn) 10% + wheat bran 10% + straw powder 12.7% + peanut cake (soybean cake) 5% + pine needle powder 10% + salt 0.7% + calcium superphosphate 1% + growth promoter 0.1% + lysine 0.1% + methionine 0.05% + oxytetracycline 20 tablets + biochemical enzyme 0.3%.

2. matters needing attention in raising pigs with distiller's grains

Distiller's grains is the leftover of wine-making, and its nutritional value varies with different raw materials. Because the starch in the raw material has become wine, the nitrogen-free extract is lower, and the protein content is relatively higher, but the protein quality is poor. Lees contain more B vitamins, but lack of carotene, vitamin D and calcium, and some alcohol remains. Therefore, the following points must be paid attention to when feeding pigs with distiller's grains:

1. Piglets, late pregnancy and lactating sows should not be fed more, so as to avoid adverse consequences such as miscarriage, stillbirth, freak, weak fetus and piglet dysentery.

2. To control the feeding amount of lees, generally fresh lees should not exceed 25%, and dry lees should be controlled below 10% to avoid constipation.

3. Distiller's grains can not be directly used to feed pigs, but should be heated before feeding to make the alcohol evaporate.

4. After feeding distiller's grains to pigs for a period of time, stop feeding for 7-10 days and then feed again to prevent chronic alcoholism.

5. The lees that can not be fed for a while should be thoroughly preserved in the cellar or on the cement floor, and the moldy and deteriorated parts of the surface should not be fed to pigs.

Using distiller's grains as feed is now more common in rural areas, but it must be fermented before use.
