Compound feed for preventing constipation of sows in gestation period and preparation method thereof

Abstract

The invention discloses a compound feed for preventing sow constipation during gestation and a preparation method thereof, and belongs to the technical field of animal nutrition. The compound feed comprises the following components: corn, bran, soybean meal, beet pulp, apple pomace, soybean oil, calcium hydrophosphate, stone powder, lysine, methionine, threonine, sodium chloride, sodium sulfate, sodium bicarbonate, choline chloride, citric acid, a compound organic trace element premix, a compound vitamin premix, a compound enzyme preparation, a compound microecological preparation, an antioxidant and a mildew preventive. The added bran is a byproduct of wheat processing flour, the protein content of the bran is high and is 12.7%-29.5%, the content of B vitamins is high, the content of crude fibers and sulfate is high, and the bran has the effect of slightly causing diarrhea. The wheat bran is a good feed for sows, can adjust daily ration energy concentration and promote digestion, enables sows and fetuses in the middle and later periods of pregnancy to gain weight quickly, compresses intestinal tracts, causes constipation of pigs more easily, is fed with the wheat bran with a laxative effect, and can smooth the intestinal tracts and avoid abortion of the fetuses caused by constipation.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to a compound feed for preventing sows from constipation during pregnancy and a preparation method thereof. Background technique [0002] In recent years, my country's pig industry has developed rapidly, and the pig industry has changed from the original decentralized breeding to highly specialized intensive breeding. Under the intensive breeding conditions, sow feeding has been paid more and more attention by people. During the breeding process of sows, the problem of sow constipation is becoming more and more serious, especially the lack of exercise caused by feeding in positioning stalls, coupled with the stress caused by sudden changes in the environment, reduces feed intake and drinking water, which in turn causes intestinal movement Disorder and constipation. Constipation in sows in many large pig farms is as high as 70%. Constipation in sows will direct...

Problems solved by technology

[0004] The specific hazards of sow constipation are as follows: the heat generated by feces fermentation will increase the temperature of the rectum, which will cause the temperature of the sow to rise; the toxins produced by feces fermentation will damage the organs of the body, causing various inflammations, such as metritis, and also It will aggravate the udder edema of sows, and cause mastitis in severe cases. Mastitis and the toxins produced will cause diarrhea in piglets; constipation will cause anorexia in sows, which will cause weak delivery in sows, and the rectum full of feces will compress the birth canal. It will cause dystocia, stillbirth or miscarriage in sows; constipation can cause depression or irritability in sows, restlessness in sows, easy crushing, killing, and killing of piglets; constipation can cause malnutrition in sows, which in turn affects the growth and development of piglets; The defecation of sows is not smooth, and the residual time in the intestine is long, and harmful bacteria multiply in the feces, which increases the possibility of sows being infected.
