How many years can a cow breed? What are the key points of aquaculture management?

With the continuous improvement of people's quality of life, people's demand for beef is also higher and higher, and at the same time, it also promotes the development of cattle industry. If you want to obtain more benefits, you should breed cows by themselves. How many years can a cow reproduce? What are the key points of farming management?

How many years can a cow reproduce?

Approximately 3-4 years. The breeding time of cows depends on their breed and growth. A cow's genes, milk availability and the health of its breeding bulls all affect its reproductive life.

2. What are the key points of cow breeding management?

1. Feeding management

Calves grow to 6 months old pay attention to the improvement of body capacity, promote rumen function, improve survival rate, colostrum feeding, high-quality forage supply, fine management, calf survival rate can reach more than 95%. Breeding cows will be growth and development, breeding as a goal, concentrate, coarse feed for the middle stage not only to ensure the supply of nutrition, but also save feed. After 18 months of age and above, the body weight is 350kg, and then it is ready for breeding. Cow breeders pay attention to nutrient supply before and after birth to improve conception rate. Perinatal cows should be raised independently for the whole process management, postpartum disease prevention and control should be done well to ensure the health of cows.

2. Supplementary feeding technology

Because roughage protein and energy supply is less, cattle should pay attention to timely supplement concentrate during growth to ensure healthy growth and balanced nutrition. The basal cows were fed with 1.0~ 1.5 kg concentrate daily for 60 days before parturition and 1.5~ 2.5 kg concentrate daily for 120 days after parturition, which was convenient for milk production and increased conception rate. The main components of the concentrate are corn, soybean meal and bran, wherein corn 53%, soybean meal 20%, bran 25%, stone powder 1%, and salt 1%. In winter, green fodder is less important for breeding personnel to pay attention to vitamin A supplementation.

3. Mechanical equipment management

Feed processing usually requires the use of related mechanical equipment, such as sheds, straw. Breeders should combine specific environmental requirements and adhere to the applicability requirements to achieve warm and warm winter housing and avoid freezing calves. Mechanical equipment can be used by several farmers.

4. Herd management technology

Grazing in groups, such as calves, growing cows and pregnant cows, shall be adopted. Grazing plan shall be formulated according to grassland condition to ensure sufficient forage for each cow. Once there are sick cattle, weak cattle, etc. should be treated as soon as possible, save nutrients management economic input, improve the reproductive ability of cows.

5. Late pregnancy management

In the later stage of pregnancy, that is, the 6-9 months of pregnancy, the fetus grows rapidly and needs more nutrients from the mother. At the same time, the cow also needs to accumulate certain nutrients in the body to ensure lactation after calving. At this time, should be in accordance with the feeding standards with diet, should be based on green feed, appropriate mix concentrate. Concentrate selection of rich local resources of agricultural and sideline products, such as wheat bran, cottonseed cake, dross, etc., and then with a small amount of corn and other grain feed. Special attention should be paid to mineral and vitamin supplements.

6. Perinatal feeding management

Adjust feeding according to the expected date of birth and prepare for delivery. When pregnant cows are fed more concentrate, the amount of concentrate should be properly controlled in the first 2-3 days of the expected date, and concentrate can increase the content of some wheat bran, reduce salt, do not feed beet residue, distiller's grains, etc., and feed high quality hay.

7. Feeding management during lactation

Cows postpartum feeding comprehensive, especially feed protein, minerals and vitamins sufficient, coupled with reasonable exercise, cow uterus recovery fast. General postpartum 4 weeks cervical atresia, 40 days or so can be completely restored, in this estrus mating. Beef cattle have a high mating rate in 60-90 days after delivery, so it is necessary to strengthen feeding and supplement feed in one month before delivery and two months after delivery, so as to make cows pregnant again within 80 days after delivery and ensure that cows have a calf every year, thus improving the reproductive survival rate of cows, reducing feeding costs and improving the economic benefits of cattle raising.

The nutrition collocation and feeding management of cows in different periods are different. We should constantly study and improve the feeding management methods of cows to make the management methods more scientific, so as to effectively improve the benefits of breeding industry.
