Fattening technology for producing snowflake beef by using Yunnan cattle

Abstract

The fattening technology belongs to animal husbandry science of agricultural science and technology. Yunnan cattle, namely weaning bullock or cow, with the weight of 110 plus or minus 20 kg and the age of 7 months are fed with the fattening purpose according to fattening procedures; the cattle selection includes the steps that (1) according to the selection of gender and age, bullock and cow are available, the bull is castrated before the age of 3 months, and the bullock or cow can be subjected to the fattening procedure after weaning at the age of 7 months; (2) according to the figure and appearance selection, healthy cattle with rectangular figure, deep chest, wide rear quarter, big vivid eyes, thick eyelids, firm hoof quality and short and thick neck are selected; the first fattening stage is from the age of 7 months to 13 months and includes the rapid growth of bones and muscles; the second fattening stage is from the age of 14 months to 18 months and is the stereoscopic growth stage, including the rapid growth of eye muscle area, and the fat growth of abdominal cavity needs to be restrained to the maximum extent; the third fattening stage is from the age of 19 months to 24 months and requires feeding high-energy feed, the fourth fattening stage is from the age of 25 months to slaughter, the fourth fattening stage is the embellishing period of the snowflake beef production, the beef moisture and fat color need to be adjusted, and meanwhile, concentrated feed is supplemented.

Description

technical field [0001] This technology belongs to the animal husbandry science of agricultural science and technology. Background technique [0002] Snowflake beef refers to the fat deposited between the muscle fibers, which is distributed in spots and is dense and uniform, forming obvious red and white, resembling snowflake settled beef. Snowflake beef is the beef with the highest degree of intramuscular fat deposition. It is tender and juicy, with excellent taste and rich nutrition. This is incomparable to ordinary beef and belongs to high-grade beef. Snowflake beef has nutritional characteristics such as low cholesterol and high omega acid, and contains a lot of fatty acids needed by the human body. With the increase of fat content in beef, the content of cholesterol decreases instead. 1kg of snowflake beef is only equivalent to the yolk content of an egg. Cholesterol content is very beneficial to human health. [0003] The lack of specialized breeds of beef cattle in o...

The proportion of high-grade snowflake beef in beef production has always been an important indicator to measure the production level of a country's beef cattle. The production of high-grade snowflake beef is also an important way to increase the efficiency of beef cattle breeding. However, my country's high-grade snowflake beef still mainly relies on imports, and the price is very expensive
