Yellow cattle breeding precautions

First, the feeding management of calves

Calves can stand on their own within 0.5-1 hours of birth, at this time to guide the calf to eat milk, to ensure that the calf eats colostrum in a relatively short period of time. If the calf can not eat milk normally, it is necessary to do a good job of artificial lactation. Before eating milk, you should use 0.1% potassium permanganate solution to sterilize the udder to avoid diarrhea and other infectious diseases. After one week, gradually train calves to feed on hay, 15-20 days later, to train them to feed on concentrate feed, generally after 2-3 days, calves can freely feed on concentrate feed.

Second, fattening cattle feeding management

Cattle in the fattening before, should carry out a comprehensive inspection, will be weak, with the disease of the cattle timely elimination, but also according to the age, weight, gender, nutritional status of scientific groups, the implementation of group feeding, group grazing. Fattening cattle in the breeding period, should adhere to the concentrate feed as the main, roughage as a supplement, feed feeding should be in accordance with the principle of gradual increase from less to more, the crude fiber content of the ration should be controlled in more than 30%.

Third, the breeding management of breeding bulls

1, breeding bull feeding

Calf period in accordance with the general calf feeding can be, lactation period is generally 6 months (not adapted to early weaning, try to make the calf more milk, more food, grow up). Diets should be of good quality and low price, palatable, diversified, easy to digest, the volume should not be too large.

Reserve period to increase the supply of protein, minerals and vitamins feed; supply enough high-quality hay, green juicy feed or silage.

Production use period should be based on the mating or sperm collection volume plus feeding mixed concentrate. Such as barley corn 30%, bran 35%, 25% of oil cakes, bone meal 3%, 2% sodium chloride for mixed concentrate, plus the appropriate amount of cattle multi-vitamin and trace element additives.

2, the management of breeding bulls

(1) strengthen domestication management, cultivate breeding bulls early temperament docile. Keepers should be relatively stable, avoid rough teasing, to tame the main.

(2) Every day adhere to the movement, bolting management. Young bulls around 1 year old to wear a nose, wear a nose ring, rope tethering management; sports requirements every day in the morning and afternoon 1 time, each time 1.5-2h; sports or long-term tethering can lead to breeder bulls temperament, semen quality decline.

(3) Insist on brushing the cow body every day and pay attention to limb and hoof protection. Cattle body brush can be taken on cold days, dry brush, hot days shower, to keep the skin clean, blood circulation is strong, improve health; limb hoof protection should be often rinsed hoof, medicinal bath or repair hoof, to protect the limbs and hooves health.

(4) Reasonable use of breeding bulls, choose the appropriate number of breeding or sperm collection. Breeding bulls can not be used too early before maturity, generally about 2 years of age to start using, breeding or sperm collection is generally 2 times a week is appropriate, long-term use will make the bull libido decline, too much use will make the semen quality decline.

Fourth, the feeding management of pregnant cows

Heifers in the first five months of pregnancy, to do with roughage feeding, appropriate with a small amount of concentrate feed. After the cow enters the middle and late pregnancy, should gradually increase the feeding amount of concentrate feed, to ensure that the feed protein, minerals, vitamins, adequate inputs, after the success of the pregnancy of the cow, the cow should be isolated breeding, to avoid mutual collision between cows and lead to abortion.

Improved breeds, cows start breeding only after 1 week of age, strengthen feeding management in the late gestation period, set up scientific feeding methods, for calves that have reached adulthood, need to consider the time of slaughter, generally about one and a half years old can be slaughtered, farmers can independently planted pasture, reasonable control of feed feeding rate, strengthen the feeding management.
