According to the relevant experiments, rice, barley, and wheat bran were cooked and fed to pigs. Only 50 kg of 44.7 kg of raw pigs were fed. After the feed was cooked, the pigs lost 10% of their nutrition. Cooked feeds reduce the digestibility of feed due to the destruction of certain vitamins; pigs swallow the clinker without having to chew food slowly, and nutrients are too late to be fully absorbed by the gastrointestinal wall and excreted with waste. Most farmers are used to cooking green food with an iron pan, not only losing nutrition, but also causing nitrite poisoning in pigs.
In recent years, there have been four main points for scientific pig raising and professionalism in summarizing feed benefits:
The first is to avoid the destruction of feed nutrients and improve feed utilization.
The second is to save fuel. On average, each pig spends a minimum of about 100 yuan on fuel costs, cutting down forests, which helps protect the ecological environment.
The third is to save labor. Fourth, to promote the development of biogas.
Four issues need to be noticed when cooked and fed:
1. Wash green feedstuffs and whole grains before feeding, or chop and add compound feeds to mix and feed.
Second, a few feeds should not be fed. For example, if soybeans and their by-products of processing are used to make bean dregs, and after cooking or frying, the unfavorable factors such as antitrypsin contained in the product will be destroyed, and compound feed will be added. Cooked potatoes can improve palatability and prevent diarrhea. Greenish and germinating potatoes have a higher volume of solanum nigrum, causing pig poisoning, peeling and buds, and cooking to the water before feeding. Drowning water is prone to pathogenic microorganisms, and it needs to be boiled and fed.
Third, to piglets and shelf pig deworming. It is more likely to be infected by parasites than by raw feed, especially for 2-4 months old pigs. Fourth, the pig manure can only be used as a fertilizer after fermentation to prevent eggs or larvae from contaminating green feed, and to infect humans and livestock. Promoting silage technology and biogas housing for green and succulent feed is conducive to killing germs and eggs.
