Problems solved by technology

[0002] The winter breeding of domestic animals in alpine pastoral areas is mainly based on individual house feeding and captive breeding, and the separate feeding of concentrated and roughage is the mainstay. Extensive methods often lead to insufficient intake of total dry matter in the feed, or excessive intake of concentrated feed in a short period of time, which affects the production performance of livestock and hinders reproduction; at the same time, it is difficult to form a large-scale breeding

Embodiment 1

[0027] The full mixed ration of house feeding yak in cold season is made up of concentrated feed and roughage, and described roughage comprises silage grass, Elymus chinensis green hay; 15 days before house feeding, the ratio of described concentrated feed and roughage is 3:7; During the barn feeding period, the ratio of the concentrated feed to the roughage is 1:1; wherein, the water content of the total mixed ration is 42%-44%. The traditional coarse and intensive separate feeding method of free feeding of coarse material and limited feeding of concentrated material results in unstable ration composition and poor nutritional balance. After eating yaks, it is easy to cause a large change in rumen pH value, which is easy to damage the digestion and metabolism in the rumen The dynamic balance of dry matter causes insufficient feed intake of dry matter, reduced digestibility of crude fiber, and low feed utilization rate; the fully mixed daily ration of the embodiment of the prese...

Embodiment 2

[0048] Compared with traditional feeding by using the fully mixed ration and its feeding method of Example 1 of the present invention, the results are shown in Table 1, Table 2 and Table 3.

[0049] Table 1 Comparison of apparent digestibility of yak

[0050]

[0051] Note: The moisture content of the traditional feed is 14.01%; the moisture content of the total mixed diet is 42.65%.

[0052] It can be seen from Table 1 that the dry matter intake of yaks fed the total mixed diet group increased by 19.95% compared with the traditional feeding group; at the same time, the daily feces of yaks decreased by 37.33% compared with the traditional feeding group, and the apparent digestibility of feed The rate has increased by 23.50%; the environmental pollution caused by excretion of livestock manure has been alleviated to a large extent, and feeding the total mixed ration has significantly improved the digestibility and utilization rate of the feed.

Abstract

An embodiment of the invention discloses total mixed ration for barn feeding of a yak in a cold season as well as preparation and feeding methods of the total mixed ration. The total mixed ration is obtained by optimizing a fodder formula according to the feed intake quantity and feed intake habits of the yak by a nutrition regulation means of fine and coarse fodder mixing, nutrients are balanced in the ration with uniformly mixed components, the stable fodder structure of the yak can be guaranteed, carbohydrate, protein, fat and other nutrient substances can be simultaneously utilized in a rumen, growth and breeding of microorganisms are promoted, the microbial activity is improved, the protein synthesis rate is increased, the pH value of the rumen is kept relatively stable, rumen microorganisms are always in a stable and excellent living environment, the number and the activity of microorganisms are kept, the healthy state of the yak is guaranteed, and the production performance of the yak is improved; batch feeding and large-scale breeding can be realized in combination with the preparation and feeding methods.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a fully mixed ration for house-feeding yaks in cold seasons and a preparation and feeding method thereof. Background technique [0002] The winter breeding of domestic animals in alpine pastoral areas is mainly based on individual house feeding and captive breeding, and the separate feeding of concentrated and roughage is the mainstay. Extensive methods often lead to insufficient total dry matter intake of feed, or excessive intake of concentrated feed in a short period of time, which affects the production performance of livestock and hinders reproduction; at the same time, it is difficult to form a large-scale breeding. Contents of the invention [0003] The object of the present invention is to provide a kind of total mixed ration and its preparation and feeding method for keeping yaks in house in cold season, so as to solve the above-mentioned problems. [0004] I...
