Premixed feed for pregnant sows

Abstract

The invention provides a premixed feed for pregnant sows and aims at solving the lots of problems ofabortion, constipation, large weak piglet number and the like caused by insufficient hematopoiesis, qi tonifying Qi and dietary fiber of pregnant sow feeds. The main ingredients of the premixed feed include fish meal, fermented soybean meal and folium mori powder, main protein sources for the pregnant sows are ensured, necessary vitamins and mineral elements are supplemented for the pregnant sows by being matched with added vitamins and mineral substances, and multiple probiotics are added and can promote digestion. In addition, the folium mori can provide dietary fiber for the pregnant sows, and can improve the constipation situation of the sows by cooperating with the digestionaiding effect of the probiotics and improve digestive absorption of the nutritional ingredients. A nutritional compound bag for hematopoiesis and qi tonifying achieves hematopoiesis and qi tonifying for the pregnant sows, the digestive absorption ability of the sows is improved, and sufficient nutrition is provided forintrauterinefetuses, and fetusnutritioncontending, weak fetusabortion and the like caused by nutrition deficiency due to anemia of the sows can be avoided. In addition, the pregnant sows are sufficient in blood and qi and strong in immunity, and the survivalrate of piglets is high.

Description

technical field [0001] The invention relates to the field of premixed feed, in particular to a premixed feed for pregnant sows. Background technique [0002] In intensive and industrialized pig production, sows are considered as the "engine" of a pig farm, and the quality of sow feeding directly affects the production efficiency of the pig farm. Pregnant sows are the most important thing. Feed during pregnancy has a vital impact on pregnant sows. During pregnancy, the rapid development of the fetus in the womb robs the mother of a large amount of hematopoietic active substances to satisfy its own rapid growth. This can easily lead to anemia in pregnant sows. After the sow is anemic, the digestion and absorption rate of nutrients decreases, the mother gets less nutrition, the fetus in the uterus gets less nutrition from the mother, the death of intrauterine embryos increases, and the number of abortions and weak offspring increases. At the same time, after the sow is pregna...

AI Technical Summary

Problems solved by technology

At the same time, after the sow is pregnant, in order to maintain the pregnancy, the progesterone in the body, especially the progesterone, increases. The progesterone has the function of relieving the contraction of the smooth muscle. Due to the weakening of the contraction of the smooth muscle, the intestinal peristalsis slows down, and the lack of exercise of the sow causes food Accumulation in the gastrointestinal tract often causes intractable constipation. In order to relieve constipation in sows, a large amount of bran can only be added to the feed, but the content of mycotoxins in bran is particularly high, which often causes abortion and weak piglets in sows.
