Problems solved by technology

[0003] In addition, although the meat quality of yak is high in protein, its fat content is low at the same time, and the taste is rougher than that of ordinary beef cattle.
This phenomenon is affected by many factors, and there is no good solution yet

preparation example Construction

[0042] The preparation method of the concentrate is as follows: adding each component into a mixer, adding 20-35 parts of water, pulverizing, stirring, and mixing at 25-35° C., and continuously stirring for 2-3 hours, extrusion molding, drying at room temperature, Get the required feed.

[0043] Wherein, the formula of the feed additive is: in parts by weight, 10-15 parts of Gynostemma japonica, 3-5 parts of Panax notoginseng saponins, 3-5 parts of berberine, 1-3 parts of puerarin, 1-3 parts of puerarin Parts of black plum, 2 to 5 parts of Shouwu Teng, and 1 to 3 parts of Salvia.

[0044] Wherein, in order to remove the poisonous and harmful substances in the Sauerkraut, it is preferable to pre-treat the Sauvignon Blanc before using, and the present invention adopts the supercritical fluid extraction method to remove the poisonous and harmful substances therein.

[0045] The specific processing method is as follows:

[0053] Example 1: Demonstration of the pretreatment effect of Shouwu Teng

[0054] 1. Weigh 20 groups of equal amount of Sauerkraut that has been pulverized and passed through an 80-mesh sieve, and each group is set to 3 repetitions, and pretreated according to the above method. The conditions of each group of pretreatment are shown in Table 1. In addition, a group of Shouwu vines with equal amount, crushed and sieved, without pretreatment, was set as a control group.

[0057]

[0058] 2. Before and after pretreatment, the content of Cu and Pb ions were measured in S. Determination of glycoside content; and calculate the difference rate (%) of each content respectively, the difference rate=(M1-M2) / M1, the M1 is the content of the analyte before pretreatment, and M2 is the analyte after pretreatment. substance content. Among them, the difference rate less than 1‰ is reg...

[0062] Example 2: Effects of feed additives on the growth and meat quality of yak

[0063] 1. Prepare 12 groups of concentrates and mixtures according to the above method, wherein the coarse material is selected from highland barley straw, and the diameter is controlled at 3-5cm. The specific components of the feed additives in each group of concentrates and mixtures are shown in Table 3. Among them, the concentrate formula is: by weight, 12 parts of highland barley, 37 parts of corn, 42 parts of soybean meal, 1 part of VC, 1 part of VE, and 2 parts of feed additives. The preparation method of the concentrate is as follows: adding each component into a mixer, adding 35 parts of water, pulverizing, stirring, and mixing at 25° C., stirring continuously for 3 hours, extruding, and drying at room temperature. The microbial composition was, in terms of viable bacteria, Bacillus subtilis: Bacillus licheniformis: Lactobacillus: Bifidobacterium = 1:1:1:1. The control group refers to...

Abstract

The invention belongs to the field of animal husbandry, and in particular relates to a feeding system for yaks in high-altitude mountainous areas. A feeding system, comprising a cowshed, the top of the cowshed is provided with at least two layers of roofs that are arched upwards, and ventilation skylights are arranged in the middle of each roof, and ventilation bins are arranged on the skylights, and the cross-section of the ventilation bins is The skylight is arched upwards, and the two ends of the arch are ventilated. Utilizing the feeding system and method provided by the invention to feed cattle can effectively reduce the mortality rate of yak feeding in winter, shorten the time for slaughtering yaks, and improve the quality level of yak meat.

Description

technical field [0001] The invention belongs to the field of animal husbandry, and in particular relates to a yak feeding and feeding system in high-altitude mountainous areas. Background technique [0002] Yak is one of the mammals that grow at the highest altitude. It is mainly distributed in the Himalayas and the Qinghai-Tibet Plateau. Its living environment is characterized by high altitude, low oxygen, large temperature difference, and extremely cold winter. At the same time, due to various reasons such as history and natural conditions, yak feeding still mostly relies on a very traditional feeding mode such as grazing, which keeps yak in a vicious circle of "strong in summer, fat in autumn, thin in winter, and dead in spring" for a long time. Yaks reach their peak body weight from October to November every year, and then lose weight seriously, their body weight continues to drop, and they grow in a "zigzag" shape. As a result, fattening cattle often do not reach the sl...
