Feed additive used for pregnant ewes in late period

Abstract

The present invention mainly relates to the technical field of breeding and discloses a feed additive used for pregnant ewes in a late period. The feed additive is prepared from the following raw materials: egg shells, walnuts, green papayas, folium ginkgo, camphor tree leaves, flos sophorae immaturus, semen pruni, herb of virgate lespedeza, sea buckthorn seed oil, fructooligosaccharides, compound proteins, compound minerals, compound vitamins and grape wine yeasts. The feed additive is rich in raw materials and balanced in nutrition, protects gastrointestinal functions of the ewes, is easy to digest and absorb, reduces sickness rate of the ewes by 4.7%, promotes the growth and development of fetuses, decreases miscarriage rate by 3.2%, significantly improves the breeding efficiency, and increases economic incomes of farmers by 9.8%. The eggshells, walnuts and green papayas are subjected to primary fermentation with the grape wine yeasts, fragrance components are increased, palatability is improved, the feed additive is balanced in nutrition, promotes digestion and absorption of the ewes, improves feed utilization and disease resistance of the ewes, speeds up the secretion of milk, is conducive to fetal growth, and increases the survival rate of lambs by 3.6%.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a feed additive for late pregnant ewes. Background technique [0002] The late stage of pregnant ewes refers to the second month of pregnancy in ewes, when the fetus grows rapidly, and 90% of the lamb's birth weight completes growth during this period, and the ewes need to supplement a large amount of nutrition to promote fetal development, but improper Blindly adding feed will not only increase the absorption of nutrients by ewes, but also oppress the fetus because it is difficult to digest, affect normal development, and even cause miscarriage. [0003] In order to supplement the nutrition of pregnant ewes, many farmers will add additives to the feed, but many of the additives currently available on the market contain hormones and antibiotics, which will adversely affect the health of ewes and affect the normal development of the fetus. Therefore, there is a need for ...

[0003] In order to supplement the nutrition of pregnant ewes, many farmers will add additives to the feed, but many of the additives currently available on the market contain hormones and antibiotics, which will adversely affect the health of ewes and affect the normal development of the fetus. Therefore, there is a need for a safe and healthy feed additive for later stages of pregnant ewes
