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.
