Cold season nutrition-balanced compound yak block and technology for producing same

Abstract

The invention provides a cold season nutrition-balanced compound yak block, each kg of the block consists of the following raw materials of: 0.3-0.6g of zinc sulfate, 0.2-0.4g of copper sulfate, 0.01-0.02g of sodium selenite, 0.02-0.25g of potassium iodide, 0.02-0.04g of cobalt chloride, 10-20g of magnesium oxide, 70-100g of calcium hydrophosphate, 80-120g of puffing corn seed powder, 50-80g of bran, 20-40g of rapeseed meal, 50-100g of high-energy fat powder, 20-40g of urea, 150-250g of salt, 200-300g of bentonite, 30-60g of portland cement, 80-150g of molasses and 20-40g of vitamin premix. In addition, a technology for producing the block is provided, and better combines a chemical solidification technology and a mechanical pressing technology; and according to the seasonal variation characteristics of forage grass feed and nutritional statuses during yak raising, through taking the compositions and quantities of earth mineral elements which are ingested by the yak into consideration, the technology optimizes and adjusts the formula of the yak nutrition block, and balances the yak nutrient element supply. A curing agent has wide select sources and is low in price, and the compound yak block has balanced nutrition and larger density, is reasonable in feed intake, and is suitable to the purpose of nutrient element supplement for grazing yaks of different production levels in cold seasons.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and relates to an animal feed, in particular to a yak licking brick with nutritional balance in cold season and a preparation process thereof. Background technique [0002] Nutrient licking bricks are a simple and effective ideal way to supplement mineral elements, non-protein nitrogen, soluble sugar and other nutrients that are easily lacking in ruminants. It is widely used in ruminant livestock production systems and significantly improves the productivity of ruminant livestock to a certain extent. level, and produce good economic and production benefits. However, based on the traditional grazing system of yak production, the related research and application of yak nutrition licking bricks started late and developed slowly. At present, most of them are based on the production formula of livestock in barnyards, while ignoring the unique alpine grazing system of yaks. . [0003] Unde...

Problems solved by technology

However, based on the traditional grazing system of yak production, the related research and application of yak nutrition licking bricks started late and developed slowly. At present, most of them are based on the production formula of livestock in barnyards, while ignoring the unique alpine grazing system of yaks.

[0003] Under traditional grazing conditions, grassland animal husbandry has serious seasonal imbalances in the supply of forage grass. The supply of forage grass in the warm season is relatively sufficient, and the quantity of forage grass in the cold season is seriously insufficient and the quality is declining.

Unbalanced seasons lead to serious nutritional deficiencies in livestock during the long dry grass season, resulting in a large amount of fat loss, resulting in the famous "spring lack" problem, resulting in serious production losses

In the traditional grazing system, yaks eat soil extensively. On the one hand, eating soil can provide a large amount of mineral elements for yaks, which is one of the important ways to obtain mineral elements; in addition, a large amount of soil intake will cause yak dietary mineral elements The imbalance of components causes the absorption and utilization of other elements to decrease
