Embodiment 1

[0019] 1. Preparation of supplementary feed for yaks: Mix 21.13% old awns, 70.42% silage corn, 2.82% concentrated feed, 0.7% urea, 4.23g calcium bicarbonate, and 0.7% salt. Among them, the silage corn, the water content before silage is adjusted to 70%, and after kneading, cutting and crushing, the silage is wrapped with a silage wrapping machine for preservation.

[0020] 2. Supplementary feeding method: for yaks over 6 months old, the daily supplementary feeding amount is 2% of the yak's body weight; S2: for calves under 6 months old, the daily supplementary feeding amount is 0.5% of the calf's body weight; every night from 18:00 to 19:00 Supplementary feeding once, with drinking water.

experiment example 1

[0022] The various indicators of the yaks fed with the above formula were tested, and the results are as follows:

[0025] The yaks were fed with this formula, and their body weight gain and slaughter indicators were determined for 1-5 years. From the measurement results, adopting the supplementary feed ratio of the present invention to breed yaks for 3 years, its net meat rate, bone-to-meat ratio, and slaughter r...

Abstract

The invention discloses a supplementary feeding formula and a method for shortening slaughter period of a yak, and solves the problem that feeding of single silage fodder is not conducive to health ofthe yak. Meanwhile the supplementary feeding formula of the invention uses relative less compositions to shorten slaughter period of the yak and reduce cost. The supplementary feeding formula for shortening slaughter period of the yak comprises the following compositions: green hay, silage fodder, concentrate feed, urea, calcium bicarbonate and salt.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a supplementary feeding formula and a method for shortening the slaughter of yaks. Background technique [0002] With the influence of factors such as overloading and overgrazing in plateau areas, grassland degradation and desertification, grassland diseases, insect pests and rodents, etc., grassland productivity is low, especially in winter and spring. The phenomenon of death occurs from time to time, and the lack of grass also causes the cycle of yaks to be slaughtered is too long. It usually takes 5-7 years to be slaughtered. This is not conducive to the development of the yak industry and seriously restricts the economic improvement of the plateau area. The supplementary feeding formula provided by the invention can shorten the yak slaughter period to 3 years, and can improve meat quality, increase the commodity rate and breeding benefits of yaks, alleviate the pressu...
