Oven feed to pigs pay attention
Okara is a by-product of soy products processed from soybeans. It has been determined that fresh soybean dregs contain 4.7% crude protein, dry dregs contain 27.7% crude protein, and crude fiber content is about 6%, which is an ideal feed for rural pigs. However, pigs fed with bean dregs should not be fed directly. This is because the bean dregs contain anti-trypsin, which can inhibit the decomposition of legume protein by pig trypsin and affect pig growth. Heating the bean dregs by boiling them for 15 minutes before feeding them can destroy the antitrypsin so that the protein in the feed can be fully utilized. Conditional pig farmers can also feed the bean dregs after fermentation.
The proportion of bean dregs in the diet of live pigs should not be too high, because the crude protein content in bean dregs is low, the quality is poor, and there is a lack of vitamins. The mineral content is also very small and must be combined with other feeds to meet the nutritional needs of pigs. . The suitable amount of bean dregs in pig diets is: the ratio of fresh bean dregs is controlled at 25% to 30%, and the proportion of dried bean dregs is controlled at 10% or less, otherwise it is easy to cause pig indigestion.
In addition, the fresh bean dregs have more than 80% moisture content, and they are prone to spoilage and deterioration after being placed for a long time. After feeding the pigs, they cause diarrhea and even poisoning. Therefore, it should be kept as fresh as possible. If mild sourness occurs, 50 grams of lime powder or baking soda powder should be added to each kilogram of bean dregs before mixing to neutralize organic acids and increase appetite. Severely spoiled bean dregs are forbidden to feed pigs. If the bean dregs cannot be fed at one time, a small amount of salt can be added for preservation, and it can also be stored in the sun.
