Problems solved by technology

[0003] With the development of the beef cattle industry, large-scale beef cattle farms are increasing, but their fecundity tends to decline. Beef cattle in farms often show no estrus, no obvious estrus symptoms, prolonged estrus, slow ovulation, decreased conception rate and Symptoms such as early death of embryos lead to low reproductive rate of beef cattle, which has a negative impact on the development of my country's beef cattle industry

Abstract

The invention discloses a breeding method for improving the beef cattle reproduction rate, and belongs to the technical field of livestock and poultry reproduction. The breeding method comprises the steps of selection of improved variety beef cattle, cow breeding, reproduction control, pregnancy diagnosis, miscarriage prevention after mating, delivery and postpartum care. Compared with the prior art, the breeding method has the advantages that the purpose of improving the beef cattle reproduction rate is achieved by strictly controlling and managing the aspects of selection of the improved variety beef cattle, cow breeding, reproduction control, pregnancy diagnosis, miscarriage prevention after mating, delivery and postpartum care. The reproduction rate, the calf survival rate, the reproduction survival rate, the conception rate and the delivery rate of the bred beef cattle are all improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry reproduction, and more specifically relates to a breeding method for increasing the reproductive rate of beef cattle. Background technique [0002] With the continuous improvement of people's living standards, people's demand for materials has gradually shifted from quantity to quality improvement. There is also an increasing demand for high-quality meat such as beef in the diet. For the livestock and poultry breeding industry, the most direct and fundamental means to provide more high-quality beef and improve the economic benefits of beef cattle production is to improve the fertility of beef cattle. [0003] With the development of the beef cattle industry, large-scale beef cattle farms are increasing, but their fecundity tends to decline. Beef cattle in farms often show no estrus, no obvious estrus symptoms, prolonged estrus, slow ovulation, decreased conception rate and Symptoms ...
