Fully-mixed ration feed capable of reducing weaning stress of lamb

Abstract

The invention belongs to the field of sheep feeds, and particularly relates to a fully-mixed mutton sheep ration feed capable of reducing the weaning stress of a lamb. The fully-mixed mutton sheep ration feed is characterized by comprising the following components in parts by weight: 35-40 parts of corn, 5-10 parts of soybean meal, 5-10 parts of wheat bran, 5-10 parts of bombyx mori, 20-35 parts of a soybean milk powder, 2-8 parts of a yeast powder, 2-8 parts of bean stalks, 5-20 parts of silage corn, 3-8 parts of green hay, 0.5-1.5 parts of a calcium powder, 0.4-1 part of calcium hydrophosphate and 1-3 parts of a premixed feed. According to the fully-mixed mutton sheep ration feed, the stress reaction of the lamb after weaning is steady and transitional by mainly using a nutritional level and a fully-mixed ration feeding mode, the lamb keeps stable relatively after weaning, and the high-level growth quality is kept.

Description

technical field [0001] The invention belongs to the field of sheep feed, and in particular relates to a mutton sheep total mixed ration feed capable of reducing the weaning stress of lambs. [0002] Background technique [0003] With the development of the social agricultural economy, the mutton sheep industry has become the mainstream of the development of the sheep industry today. In the case of large-scale feeding, the weaning age of lambs is generally 2 months. Since the diet of lambs after weaning changes from milk-based to grass-based, lambs often have obvious weaning stress reactions. Stress can cause symptoms such as indigestion and poor appetite in lambs during weaning, and then "growth shock" or "negative growth", and even cause various diseases. Slow growth occurs for a period of time after weaning, which reduces the survival rate and Breeding rate is greatly reduced. The weaning stress response is inevitable in the production process of sheep, and it is a prod...

Problems solved by technology

[0005] However, the shortcoming of this ration formula technology using linear programming model to formulate the lowest cost formula is that it does not consider the interaction effect between feed ingredients

In addition, the feeding method adopts the feeding system of intensive and coarse feeding. This traditional feeding method has become increasingly unsuitable for the intensive and large-scale production of modern animal husbandry.

The main problems are: the fine-grain ratio is not easy to control, the pH value of the rumen varies greatly, which is not conducive to the digestion of crude fiber, and it is easy to cause abnormal rumen function, which affects the production performance and is prone to reproductive disorders
