Cow climatic infertility prevention

Although some cows have estrus in the seasons, there is no uterine inflammation, insemination is timely, but it is not pregnant, this is a dairy cow climate infertility. Because the cow's reproductive function and sunshine, temperature, humidity, feed composition and other changes and other external factors are closely related. These factors can directly affect the estrus cycle and the quality of estrus in dairy cows (all cattle farmers with practical experience will find that cows have the lowest fertility rate in the severe winter and hot summer), especially in poor feeding and management situations. The estrus cycle will end in dairy cows, and even if there is periodic ovulation, most of them do not show estrus (quiet estrus) or have estrus and do not ovulate.

Symptoms and Diagnosis The cow's genital organs are normal, with slight estrus, or no estrus. Some estrus symptoms, but not ovulation, at this time infertility after insemination is not caused by inflammation, but the quality of estrus is not enough.

When treatment and prevention alternate during the season, care should be taken to manage it according to the habits of the cows. In particular, cows must be created to adapt to the local environment as soon as possible. Even local cattle should strengthen feeding management and check estrus during climate change. Because climatic infertility is temporary, it can return to normal once the cow has adapted to the environment. If the husbandry is well managed, these cows can also conceive as usual.
