Fermented feed for increasing milk yield of yak

Abstract

The invention discloses a fermented feed for increasing milk yield of yak. The fermented feed is characterized in that main raw materials comprise, by weight, 35-45 parts of common turnip, 15-25 partsof highland barley, 5-15 parts of wheat bran, 15-25 parts of cottonseed meal, 3-7 parts of Radix Codonopsis and 3-7 parts of Ligusticum wallichii. By the use of the additive, digestion of plant raw materials can be fully and effectively promoted for animals, and digestive absorption utilization rate of plant raw materials is raised. In addition, polysaccharide substances on the surface of yeast cells can adsorb mycotoxin in the feed. Thus, bacterial diarrhoea and trophic diarherra are effectively controlled, utilization rate of the feed is raised, and growth performance is enhanced. After fermentation, the content of nutritional and functional components (such as crude protein, total sugar, reducing sugar, total acid, flavone, total phenols, triterpene, polysaccharide, etc.) in common turnip can be effectively increased, and the time of lacking oxygen of animals is effectively prolonged.

Description

technical field [0001] The invention relates to the field of feed, specifically a fermented feed for improving yak milk production. Background technique [0002] Yak is an irreplaceable biological species in the pastoral areas of Qinghai-Tibet Plateau and northwestern Sichuan. It is an important means of production, a pillar industry of the national economy in the region, and a basic industry that the majority of herdsmen have managed for generations to survive and develop. [0003] However, due to the slow acceptance of advanced management concepts in the local area, there is no concept of supplementary feeding and fattening in the feeding and management of yak, and only the local characteristic vegetation of coriander root is fed. Therefore, the growth of yak is slow, and due to lack of energy and protein, milk is produced in winter. Quantity is extremely low. Fermented feed has been widely used in the breeding process of dairy cows and sheep in the inland, which is benef...

Problems solved by technology

[0003] However, due to the slow acceptance of advanced management concepts in the local area, there is no concept of supplementary feeding and fattening for the feeding and management of yaks. They only feed with local characteristic vegetation coriander roots, so the growth of yaks is slow. Due to the lack of energy and protein, milk production in winter Very low volume
