Description
Technical Field
The invention relates to the technical field of breeding of snowflake yaks, in particular to a fine breed breeding method of snowflake yaks.
Background
Yak belongs to mammals, subclasses of beast, Artiodactyla, suborder of rumination, family of Bovidae, and subfamily of Bovidae, and is a herbivorous ruminant livestock centered on Qinghai-Tibet plateau in China and one of the special rare cattle species adjacent to alpine and alpine regions in mountain and submountain. Yak can adapt to high and cold climate, is mammal (except human) living in highest altitude in the world, and is distributed in the region with altitude of more than 3000 m in Qinghai-Tibet plateau of China. The Tibetan language of the yak is called Yake, which is commonly called 'yak' in the world, namely the Tibetan language translation. The yak is called sound image pig singing, so it is also called pig singing. The western countries are also known as tibetan cattle because they are produced mainly in tibetan regions of the Tibet plateau of China. Yak tail is like horse tail, so it is also called horse tail cattle.
The yak meat is rich in protein, amino acid, carotene, calcium, phosphorus and other trace elements, has high calorie, and has remarkable effects of enhancing disease resistance, cell activity and organ function of human body, so that the yak meat is pursued by consumers. The snowflake beef means that fat is deposited among muscle fibers to form obvious red and white beef which is similar to marbling, contains a large amount of fatty acid required by a human body, and has higher or lower nutritional value than that of common beef.
Because the yak grows slowly, the expansion of the breeding industry is subject to larger elbow stopper, so that fine breed breeding and selection of the yak are necessary, and the fine breed breeding method of the snowflake yak is provided.
