Embodiment example 1

[0026] 80 late-pregnancy female yaks were randomly divided into two groups, and a 60-day feeding experiment was carried out. One group was supplemented with a mixture of 25% concentrated feed + 65% highland barley + 10% oat at 0.30kg / head after returning from grazing at night, and the other group According to 0.30kg / head, the mixture of 60% highland barley + 40% oats was supplemented, and the results showed that the birth weight of lambs produced by female yaks in the late pregnancy was higher than that of lambs fed with the mixture of 25% concentrated feed + 65% highland barley + 10% oats. The birth weight of calves born to female yaks fed a mixture of 60% barley + 40% oats was 12% higher.

Embodiment example 2

[0028] 80 late-pregnancy female yaks were randomly divided into two groups, and a 60-day feeding experiment was carried out. One group was supplemented with a mixture of 25% concentrated feed + 65% highland barley + 10% oat at 0.30kg / head after returning from grazing at night, and the other group According to 0.30kg / head, the mixture of 60% highland barley + 40% oats was supplemented, and the results showed that the milk production of yak ewes in the late pregnancy was higher than that of yaks and ewes fed with the mixture of 25% concentrated feed + 65% highland barley + 10% oats. The milk yield of female yaks with the mixture of 60% highland barley + 40% oats is 13.2% higher.

Embodiment example 3

[0030] 80 late-pregnancy female yaks were randomly divided into two groups, and a 60-day feeding experiment was carried out. One group was supplemented with a mixture of 25% concentrated feed + 65% highland barley + 10% oat at 0.30kg / head after returning from grazing at night, and the other group According to 0.30kg / head supplementary feeding of highland barley 60%+oat 40% mixture, the results show that: the survival rate of calves born by the female yak supplemented with the mixture of concentrated feed 25%+highland barley 65%+oat 10% is higher than that of supplemented The survival rate of calves born to female yaks fed a mixture of 60% highland barley + 40% oats increased by 21.3%.

Abstract

The invention discloses a special concentrated feed for yak and a preparation method thereof. The special concentrated feed for yak comprises the following raw materials: 21.26% of a sunflower meal, 23.44% of rapeseed meal, 24.58% of urea, 8.94% of a bone meal, 12.84% of a trace element additive and 8.94% of salt. A technical scheme provided by the invention can not only ensure the safe spend of winter and spring for yak, but also can ensure nutrient supply for pregnant yak, improve the survival rate and birth weight of yak calves, and at the same time improve the survival rate of weaned calves.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and relates to a special concentrated feed for yaks and a preparation method thereof. Background technique [0002] The yak is a long-haired bovine animal that lives on the Qinghai-Tibet Plateau. It is the mammal that lives at the highest altitude in the world. It is mainly produced in areas above 3,000 meters above sea level on the Qinghai-Tibet Plateau in my country. Adapt to alpine ecological conditions, resistant to roughness and hard work. Due to the restriction and influence of factors such as the ecological environment conditions, production methods, producers' cultural level, and religious beliefs in the distribution area of ​​yaks, there are differences between different groups of yaks in different regions or even in the same region. At present, yaks in most areas only rely on natural grass pastures to obtain the nutrients they need to maintain life, grow and reproduce. Even i...
