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

[0030] The preparation method of the concentrate is as follows: put each component into a mixer, add 20 to 35 parts of water, pulverize, stir and mix evenly at 25 to 35°C, and continue to stir for 2 to 3 hours, extrude, and dry at room temperature. Get the feed you need.

[0031] Wherein, the formula of the feed additive is: by weight, 10-15 parts Gynoside, 3-5 parts Panax notoginseng saponins, 3-5 parts berberine, 1-3 puerarin, 1-3 2 to 5 parts of Shouwu vine, 1 to 3 parts of Salvia miltiorrhiza.

[0032] Among them, in order to remove the toxic and harmful substances in the Shouwu vine, it is preferable to use the Shouwu vine after pretreatment. The present invention uses supercritical fluid extraction to remove the toxic and harmful substances therein.

[0033] The specific processing method is as follows:

[0034] Shouwu vine is crushed to pass through an 80-mesh sieve and put into a supercritical extraction device, using SC-CO 2 For extraction, SC-CO 2 The flow rate i...

[0041] Example 1: Pretreatment effect of Polygonum multiflorum

[0042] 1. Weigh 20 groups of equal amounts of Shouwu vines that have been crushed and passed through a 80-mesh sieve. Each group has 3 replicates, and pretreatment is carried out according to the above method. The pretreatment conditions of each group are shown in Table 1. In addition, set a group of Shouwu vines with the same amount, crushed and sieved, without pretreatment, as a control group.

[0045] 2. Before and after pretreatment, the contents of Cu and Pb ions were measured for the Shouwu vines of each group, and 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucose Glycoside content determination; And calculate the difference rate (%) of each content respectively, described difference rate=(M1-M2) / M1, described M1 is the analyte content before pretreatment, and M2 is the analyte after pretreatment substance co...

[0048] Example 2: Effect of Feed Additives on Yak Growth and Meat Quality

[0049] 1. Prepare 12 groups of concentrated materials and mixed materials according to the above method, among which, the coarse material is selected from highland barley straw, and the diameter is controlled at 3 to 5 cm. The specific components of the feed additives in the concentrates and mixtures of each group are shown in Table 3. Wherein, 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 additive. The preparation method of the concentrate is as follows: put each component into a mixer, add 35 parts of water, pulverize at 25°C, stir, mix evenly, and keep stirring for 3 hours, extrude, and dry at room temperature to obtain the product. The microbial composition is, according to the amount of viable bacteria, Bacillus subtilis: Bacillus licheniformis: Lactobacillus: Bifidobacterium = 1:1:1:...

Abstract

The invention belongs to the field of livestock breeding, and particularly relates to a breeding method for yaks in a high-altitude mountain area. The breeding method specifically comprises the stepsof firstly, feeding the yaks with microbial fermentation materials, after feeding is completed, feeding the yaks with fine feed, and after feeding is completed, feeding the yaks with coarse materials,wherein the microbial fermentation materials are prepared by fermentation of the fine feed, the fine feed comprises a feed additive, and the feed additive comprises fiveleaf gynostemma herb, panax notoginseng saponins, berberine, puerarin, fructus mume, caulis polygoni multiflori and roots of red-rooted salvia. The breeding method is adopted for feeding the yaks, the death rate of the bred yaks in winter can be effectively lowered, the slaughtering time of the yaks is shortened, and the meat quality of the yaks is improved.

Description

technical field [0001] The invention belongs to the field of animal husbandry, and in particular relates to a method for raising yaks in high-altitude mountainous areas. Background technique [0002] Yak is one of the mammals that grows at the highest altitude. It is mainly distributed in the Himalayas and the Qinghai-Tibet Plateau. Its living environment has the characteristics of 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 the extremely traditional feeding mode of grazing, making yaks in a vicious circle of "strong in summer, fat in autumn, thin in winter, and dead in spring" for a long time. Yaks reach the peak weight of the year from October to November every year, and then lose weight seriously, and their weight continues to drop, showing a "zigzag" growth. As a result, fattening cattle often do not reach the slaught...
