Management techniques for efficient breeding of Beef cattle

Requirements for environmental facilities

The suitable temperature for cattle growth is 10 ℃ 25. Due to the use of closed house ties, the enclosure is required to have good lighting, drainage, ventilation and heat preservation, which is convenient for disinfection, ventilation, adjustment of temperature and humidity, fly and rodent control, etc., and requires no noise, no water quality and air pollution.

Requirements for calves to be fenced

The healthy calves with weaning weight of about 200 kg at the age of 5-6 months were selected, and the best hybrid male parents were Angus, Limousin, Charolais, Simmental and Piedmont. In addition to fully disinfecting the enclosure before entering the fence, the newly purchased calves should also be disinfected with 0.3% peracetic acid solution on the body surface, and the cattle with more lice mites should be sprayed with 2% trichlorfon solution.

Management of adaptation period of calves after being fenced

The adaptation period is generally 20 days after 15 seconds. During this period, adjust the diet of cattle, feed some easily digestible forage, and pay attention to their intake and activities. Deworming began 7 days later, and 0.1 grams per kilogram of body weight was given with Shengxing. If there is an in vitro parasite, 40 milligrams per kilogram of body weight can be given again with trichlorfon on the 7th day after deworming. From the 5th day after entering the fence, 30 grams of salt, 60 grams of urea, 60 grams of urea, 60 grams of oncolin, 7 kilograms of distiller's grains mixture (5 parts of distiller's grains and 1 portion of bran,) were gradually added to each cow's diet, in which lees, urea and oncolin were gradually increased from least to at most, mixed with other diets into wet materials, and drinking water was prohibited within 1.5 hours after eating. If there is ammoniated feed, urea can not be fed, ammoniated feed or microsilage can be used to gradually replace roughage. Strengthen epidemic prevention for fenced cattle and regularly inject corresponding vaccines.

Feeding and management of fattening period

The fattening period takes 11-13 months, and the body weight is in the early fattening stage before 250kg, and enters the intensive fattening stage from 250kg. At this stage, cattle can be given a needle of fertilizer, after use, the meat quality can meet the international export standards. One time is fine. During the fattening period, the activity of cattle should be restricted and fed once at 6 o'clock in the morning and evening, first coarse feed and then concentrate feed, and the water temperature should not be lower than 4 ℃. The diet should be rationally allocated according to the nutritional needs of cattle at different growth stages, and the feed should be changed step by step within 3 days. During the whole fattening process, attention should be paid to observing the feed intake and digestion of cattle, so that the problems can be found and solved quickly, and sudden death phenomena such as acidosis, urea (ammonia, poisoning, etc.) should be avoided as far as possible. If there is unease within 1 hour after eating, symptoms such as eyeball and muscle tremor, drooling foam and so on, cardiotonic and diuretic drugs should be injected immediately. At the same time, litmus test paper was used to determine the pH of rumen and urine (the normal pH value of bovine urine was 7.7 ml 8.7, when the pH value of urine was higher than the normal value, the cattle were fed with vinegar 500 ml, sugar water 500 ml, if the urine was acidic, 200 grams of soda plus 500 ml of water, infusion, gastric lavage, diarrhea and so on.
