Special nutrient block for dairy cows in Qinghai-Xizang region and preparation method thereof

Abstract

The invention discloses a special nutrient block for dairy cows in Qinghai-Xizang region and a preparation method thereof. The special nutrient block for dairy cows in the Qinghai-Xizang region comprises the following components in parts by weight: 600-800 parts of salt, 80-130 parts of bentonite, 5-8 parts of copper sulfate which contains 25% of copper by mass ratio, 6-9 parts of zinc sulfate which contains 34.5% of zinc by mass ratio, 3-5 parts of manganese sulfate which contains 31.8% of manganese by mass ratio, 14-20 parts of potassium iodide which contains 2% of potassium by mass ratio, 3-6 parts of sodium selenite which contains 1% of sodium by mass ratio, 1-8 parts of cobalt chloride which contains 1% of cobalt by mass ratio, 3-7 parts of ferrous sulfate which contains 30% of iron by mass ratio and 80-130 parts of molasses.

Description

technical field [0001] The invention relates to a trace element nutritional licking brick specially used for dairy cows in the Qinghai-Tibet Plateau region and a preparation method thereof. There are molasses, bentonite, salt, ferrous sulfate, manganese sulfate, zinc sulfate, copper sulfate, cobalt chloride, potassium iodide and sodium selenite in the nutritional lick brick of the present invention. Background technique [0002] The seasonal supply of forage in the Qinghai-Tibet Plateau is seriously unbalanced, and the special geological structure, soil type, climate characteristics, and vegetation type are all important factors affecting the soil-grass-cow mineral system. The low-temperature environment of the Qinghai-Tibet Plateau makes the soil microbial activity low, organic matter decomposes slowly, and the soil available nutrients are low, especially the soluble salt content is low, and the pasture ash content is low. Therefore, some mineral elements such as copper, ir...

AI Technical Summary

Problems solved by technology

[0007] The above prior art is aimed at ruminant special feed in low-altitude areas, and does not take into account the characteristics of high-altitude and low-oxygen areas, especially the geological structure, soil type, climate characteristics, and vegetation types of the Qinghai-Tibet Plateau. Therefore, the above-mentioned technologies cannot solve the problem of low-oxygen conditions. Problems Existing in Nutritional Supplementary Feeding of Dairy Cows in the Qinghai-Tibet Plateau at High Altitude

At present, in the breeding process of dairy cows on the Qinghai-Tibet Plateau, there are problems such as insufficient crude protein of main plant resources, low digestibility, unbalanced mineral and trace elements, and overuse of antibiotics.
