Improve feeding environment to promote difficult pregnancy

1 Feeding management

The quality of feeding and management will directly affect the conception rate of cows. Some cattle farmers, because they do not pay attention to scientific methods, still use traditional methods to raise cattle: cows don't have sheds, feed on troughs, and do not move on time; corn stalks are bundled to give light to eat leaves; cornmeal is diluted with water to drink, etc. Not conducive to nutrient absorption and digestion, so that lack of nutrients in cows affect fertility.

In order to prevent malnutrition of cows, full-rate feeds should be allocated according to individual conditions to achieve energy and protein balance. Forage and feed should be finely processed and fed on time. Pregnant cows need protein and vitamins. In terms of management, the cows are provided with a comfortable living environment. The enclosures are cool in winter and cool in summer, ventilated and dry, and exercise on time. This will ensure the normal breeding of the cows.

2 Environment

Seasonal changes have a significant effect on the reproductive capacity of cows. From March to May, the cows were fed for one winter and their sensation was good. The estrus was normal and the follicles developed normally. It was easy to suffer from fetuses. From June to August, the weather is hot, and the temperature is high. Some cows have abnormal estruss, such as fake estrus and intermittent estrus. The cow's conception rate is not high during this season and the embryo mortality is high. Therefore, we must carefully observe changes in cow estrus, accurate identification, timely insemination. From September to October, the estruss of cows were normal during this season and they were susceptible to fetuses. In northern regions, winters are relatively cold, and cows often experience irregular estrus cycles and fake estrus. In particular, cows who drink cold water often have reproductive dysfunction. At this time we must pay attention to the living environment of the cows. The sheds should be kept warm, the light should be sufficient, and warm water should be provided. Cows imported from other places must pay more attention to the impact of environmental changes on them.
