Composite nutritional type lick brick for Tibetan sheep and preparation method thereof

Abstract

The invention provides a composite nutritional type lick brick for Tibetan sheep and a preparation method thereof. The composite nutritional type lick brick for Tibetan sheep comprises the following components in percentage by weight: 14-18% of corn powder, 5-8% of wheat bran, 4-7% of rapeseed dregs, 13-17% of molasses, 7-10% of urea, 12-17% of table salt, 1-3% of calcium hydrophosphate, 1.5-2.5% of calcium carbonate, 3-6% of sodium bicarbonate, 0.5-1.5% of sodium thiosulfate, 0.65-1% of coating composite multi-vitamins, 0.35-0.5% of rumensin, 6-9.5% of bentonite, 13-16% of cement and 1% of a premix; the premix comprises the following components in percentage by weight: 5-8% of ferrous sulphate, 2.1-3.3% of copper sulphate, 9-15% of manganese sulphate, 7-11% of zinc sulphate, 0.1-0.5% of sodium selenite, 0.8-1.1% of potassium iodide, 0.4-0.6% of cobalt chloride and 61.7-74.4% of bentonite. The lick brick prepared by the preparation method provided by the invention is rich in nutrition, reasonable in hardness design, proper in feed intake, low in immersion loss rate, and capable of providing balanced nutrition for the growth and development of the Tibetan sheep, increasing the feed conversion rate and improving the reproductive performance of the Tibetan sheep, and promoting the propagative organ development of female Tibetan sheep.

Description

technical field [0001] The invention relates to an animal feed and a preparation method thereof, in particular to a compound nutritional licking brick for Tibetan sheep and a preparation method thereof. Background technique [0002] Tibetan sheep is an ancient breed of sheep unique to the Qinghai-Tibet Plateau in my country. It is mainly distributed in Tibet, Qinghai, northern Sichuan and southwestern Gansu. It has long been the main means of living and economic source for herdsmen in Tibetan areas; More than ten thousand, it is the largest number of livestock on the Qinghai-Tibet Plateau, which constitutes the main body of the sheep-raising industry on the Qinghai-Tibet Plateau, and is also an important part of my country's sheep-raising industry; the protein content of Tibetan mutton is higher than that of beef, pork, goat, and small-tailed cold mutton And Mongolian mutton, rich in amino acids, high in free amino acids necessary for the human body, high in minerals and vitam...

Problems solved by technology

[0003] However, for a long time, Tibetan sheep have been raised and managed by grazing all year round. The whole year is divided into winter and spring pastures and summer and autumn pastures. There is generally no supplementary feeding in the cold season. Low grass and livestock conflicts; the harsh natural environment of the Qinghai-Tibet Plateau makes the grass growing season short, with a dry period of up to 7 months, the growth rate of the grass is slow, and the grass yield is low. The grass is mainly grasses and sedges. Moreover, the mineral elements in the soil on the Qinghai-Tibet Plateau are unbalanced, and the protein and ash content of the pasture is low; in the cool-season withered period, the energy and protein content of the pasture significantly decrease, while the fiber content increases significantly, and the nutritional value of the pasture is seriously reduced. Grass production in cool-season pastures has been severely reduced, and Tibetan sheep have been starving for a long time. The intake of nutrients such as energy, protein, minerals, and vitamins has been seriously insufficient for a long time, which seriously affects the growth and development of Tibetan sheep and hinders the development of Tibetan sheep. The production efficiency of sheep and the economic benefits of Tibetan sheep breeding; for the current production status of Tibetan sheep, supplementary feeding is urgently needed to increase the intake of nutrients for Tibetan sheep, thereby improving the production efficiency and economic benefits of Tibetan sheep

[0004] Supplementary feeding with licking bricks is a convenient and efficient way of supplementary feeding. Supplementary feeding with licking bricks can make up for the nutritional deficiency and nutritional imbalance of natural pastures, so as to meet the needs of Tibetan sheep for energy, protein, minerals and vitamins for growth and development; however, Due to the differences in breeds and growth environments, the existing mutton sheep breeding standard parameters are not suitable for guiding the production of Tibetan sheep, and the brick licking formula produced based on the existing mutton sheep breeding standards is not suitable for supplementary feeding of Tibetan sheep; the existing Tibetan sheep The vitamins in licking bricks are easily destroyed during production, storage, feeding, etc., and the vitamins in licking bricks are easily degraded in the rumen, and the utilization rate is not high; the existing Tibetan sheep feeding licking bricks are generally not high in hardness. It is easy to cause Tibetan sheep to eat too much, leading to poisoning of Tibetan sheep, and the loss rate of immersion is relatively high, and the loss and waste of supplementary feeding in the wild is serious in rainy days

[0005] Shen Yuying, Wen Hong and others from Lanzhou University invented "a special compound additive licking brick for Tibetan sheep" (patent number: 201010551579.2) for supplementary feeding of Tibetan sheep in winter, which can supplement the crude protein and ash content of plants in the Qinghai-Tibet area The phenomenon of unbalanced mineral elements and low soluble salt can make up for the lack of nutrients in plateau Tibetan sheep due to unbalanced food intake, improve physical fitness and growth and development, achieve fat preservation in winter and spring, and improve resistance to natural disasters, especially snow disasters ability; but the Tibetan sheep mentioned in the invention supplementary feeding and licking bricks did not solve the problem of promoting the growth and development of Tibetan sheep, especially the development of reproductive organs of ewes and licking bricks in case of rain.
