Mating time and points for attention of cows

Cattle farmers all know that cows have broken estrus and ovulate quickly, and there is plenty of feed in autumn, which is when the bull is energetic and is also the best breeding world. However, whether there are many factors affecting the success of cow breeding, once the best time is missed, it will lead to breeding failure and cause losses, so when is it better for cows to breed? What are the points for attention? Let's get to know it.

The best time for cows to breed

1. After 12-18 hours of estrus, cows can be mated in accordance with the principle of "mating in the morning estrus in the afternoon and mating in the morning after estrus in the afternoon".

2. when the cow's sexual desire disappears or disappears for 5 hours, the cow does not accept climbing, the performance is quiet, the vaginal mucus is thick, and the mucus is pulled and contracted continuously for 7-8 times with the index finger and thumb.

3. Rectal examination was performed in the third stage of follicular development, that is, follicular maturation, and ovulation was performed 10-12 hours after mating. If the follicle still did not break and ovulate, it should be mated again.

II. Matters needing attention in breeding

1. Getting fat

Before mating comes, the cows of the right age should also have medium body condition, while the cows in poor condition can appropriately adjust the feed ratio, increase the times of nutrition and supplementary feeding, prolong the grazing time, mow the grass and feed the cattle to promote oestrus and ovulation. At the same time, we should also pay attention to nutritional balance, so as to avoid excessive intake of protein and energy feed, resulting in cow obesity, affecting the quality of breeding.

2. Reminder

Chase the cow with the bull in estrus to promote estrus, or take hormone production for the non-estrous cow and inject the cow with 25-35 mg of diethylstilbestrol or 40-60 mg of diphenylethane, which can also make the cow mating.

3. Timely breeding

After estrus, cows lose their appetite, get excited, like to get close to the bull and climb across each other. The vagina is often accompanied by white translucent mucus outflow, and a small amount of blood from the vagina of individual cows, which is the best time to breed.

4. Strengthen the management

During the breeding period, bulls should be fed with green fodder and concentrate, and during busy periods, animal feeds such as eggs and fish meal should be added. Cows should not exercise strenuously within 1-2 hours of mating, and try to avoid drinking water or overeating. Feed at night after half a month of breeding, and provide clean drinking water containing a small amount of salt to promote the implantation of fertilized eggs. It is strictly forbidden to feed moldy, spoiled, frozen, toxic, excessive acidity or strongly irritating feed to prevent enteritis, miscarriage, weak fetus or stillbirth.
