Many people don t know about the two more methods of organic cow breeding, what are the measures o

It must be ventilated in time, and it should also be disinfected and cleaned up, and it should also be mated, and some varieties of good quality should be selected, and some fresh forage should be fed in time.

To improve the reproductive rate of cows, it is also necessary to arrange production correctly, pay attention to scientific feeding, and also pay attention to the physical strength of cattle, prevent miscarriage, protect the body of cattle and so on.

Attention should be paid to supplementing the nutrition of the cow, the weight of the cow should be increased, the nutritional status of the cow should be paid attention to, the diet of the cow should be paid attention to, etc., these aspects are all things that should be paid attention to.

Put more effort into their feed, choose some with higher nutritional value, and should clean the living environment more, and after vaccination, you can improve the performance of reproduction.

Timely supplement the cow with nutrients, add some other ingredients to the feed, ensure protein intake, supplement crude protein in time, and control the weight of the cow.

First of all, there must be a clean barn, the temperature should be kept at about 20 degrees, not too low, the nutrition should keep up, the cows should be fed some high-protein food, you can feed some corn sorghum or bran, and drink some clean water, so as to increase the number of cows.

If you want to increase the number of cows, you should go to a reasonable feeding, usually increase some fertilizer feeding, choose some concentrate feed to feed, do a good job of nursing, keep the factory clean and hygienic, and maintain a warm environment.

After the cow is conceived, it is necessary to do a good job in the corresponding management, and the cow must be fed separately to avoid serious viral or bacterial infection, and to choose the correct time of conception, to increase the number of feeding of the cow, and improve the body resistance of the cow.

It is necessary to improve the breeding technology, pay attention to the diet of the cow, you can eat more calcium-supplementing food, you must pay attention to the surrounding temperature, and you must arrange the proportion of food reasonably during pregnancy.

Economic crossbreeding is a simple crossbreeding, which refers to crossbreeding with excellent breeds of bulls with low production performance, or crossbreeding with two breeding cattle with high production performance, in order to take advantage of the heterosis of the hybrid generation, and all the hybrid offspring are used for fattening, which is a widely used hybrid method in China.

Let's take a look at what are the ways to cross cows economically.

1. The common crosses between two varieties include the crossbreeding of meat or dual-use breeds and local cattle, and the crossbreeding of meat breeds and dairy breeds.

Meat or both-use breeds are crossbred with local cattle.

If Simmental or Charlotte cattle are crossbred with local cattle, the hybrid generation born grows fast, matures early, is heavy, has good fattening performance, and has low requirements for feeding management, all of which are used for fattening, which is the most commonly used economic hybrid method in production.

Meat breeds are crossed with dairy breeds.

Low-yielding cows are crossed with beef bulls, and the resulting crossbred offspring are fattened after weaning, taking advantage of their hybrid advantages to improve growth rates and beef quality.

2. Reincarnation crossbreeding refers to the selection of two or more excellent breeds of breeding bulls, one of the breeds of breeding bulls first mates with local cows, and the hybrid generation of cows then mates with another breed of breeding bulls, and then continues to alternately use the two breeds of breeding bulls that are not related to the hybrid cows, so that they can maintain a certain heterosis from generation to generation.

The advantage of reincarnation crossbreeding is that reincarnation hybrid cows can be used in large quantities, and only a small number of purebred paternal parents need to be introduced.

According to studies, the reincarnation of two breeds can increase the average weight of calves by 15%, and the reincarnation of three breeds can increase the average weight of calves by 19%.

3. The terminal bull hybrid system involves three breeds, that is, the bull of the A breed is mated with the purebred cow of the B breed, and the hybrid generation of the cow is mated with the bull of the C breed, and the hybrid second-generation calf is no longer crossbred regardless of the male and female all fattening.

This hybrid method is widely used in foreign beef cattle production.
