Composite additive for improving reproductive performance of female raccoon dogs and preparation method thereof

Abstract

The invention discloses a composite additive for improving reproductive performance of female raccoon dogs. The composite additive is fed in a mating period, can enhance ovarian function, promote follicle development and maturation, effectively reduce the phenomena of estrus retardation, non-concentration, unconspicuousness, no ovulation, missed mating and the like of female raccoon dogs, and improve the mating rate and reproductive rate of female raccoon dogs. After mating, the additive is fed, luteinizing in bodies of the female animals is promoted, implantation of fertilized eggs is promoted, the phenomena that the fertilized eggs are not implanted, false pregnancy occurs, nonpregnant occurs, embryonic absorption occurs and the like are prevented and reduced, and the pregnancy rate andthe farrowing rate of the female animals are increased; the late pregnancy period is the highest nutritional requirement period of the fetus, and the product can promote the nutritional absorption ofthe fetus and ensure the healthy development of the fetus, thereby reducing the occurrence of dead fetus, rotten fetus, dystocia, abortion, weak cubs and the like; and when the product is continuouslyused in the lactation period, female animals can be promoted to secrete milk, the lactation yield is increased, the lactation period is prolonged, and the phenomena of weak piglets, turning around and the like caused by hypogalactia are reduced, so that the survival rate, the healthy piglet rate and the uniformity of the piglets are improved.

Description

technical field [0001] The invention relates to the technical field of reproductive additives for female raccoon dogs, in particular to a composite additive for improving the reproductive performance of female raccoon dogs and a preparation method thereof. Background technique [0002] Raccoon raccoon dog is an omnivorous fur animal of the order Carnivora Canidae. It is widely distributed in my country and is easy to domesticate. Artificial breeding has spread to more than 20 provinces (regions) in the country. The fluff of raccoon dogs can be spun to weave clothes, the tail hair and needle hair can be used to make high-grade brushes, beard brushes, etc. The gallbladder, heart, whip, etc. can be used as medicine. One litter per year can produce 6-9 cubs. At the end of the year, the skin can be taken for sale as a commodity, and it can be put into the output of the year, which has high economic value. In recent years, the supply of raccoon fur has been in short supply, and t...

Problems solved by technology

Raccoon raccoon breeding is one of the good projects for farmers to get rich in recent years. Artificial raccoon raising needs to pay attention to management, including the feeding and management of young raccoon dogs and adult raccoon dogs. The feeding management of adult raccoon dogs is divided into breeding preparation period, breeding period and pregnancy period. , lactation and recovery period feeding and management, etc., but the existing breeding of female raccoon dogs has the following disadvantages: First, the estrus period of female animals is slow, and in the estrus period, it is easy to show that it is not concentrated, not obvious, not ovulating and missing mating, etc. phenomenon, which in turn affects the mating of female animals; secondly, stillbirth, bad fetus, dystocia, miscarriage and weak cubs are prone to occur during pregnancy, which reduces the quantity and quality of female litter; finally, female animals are prone to It is manifested as less milk, and the lack of milk is likely to cause weak cubs and U-turns, which in turn reduces the probability of cub survival
