Feed additive capable of preventing and controlling drylot-fed sheep limb-foot disease and preparation method

Abstract

The invention relates to a feed additive capable of preventing and controlling a drylot-fed sheep limb-foot disease and a preparation method. The invention is mainly to solve the problem of decreasedcomprehensive breeding benefit of drylot-fed sheep due to easiness in suffering from the drylot-fed sheep limb-foot disease for the drylot-fed sheep. The feed additive is composed of zinc methionine,copper methionine, rumen bypass vitamin A, rumen bypass vitamin D, rumen bypass vitamin E, rumen bypass biotin and corncob powder. The preparation method comprises the following steps: mixing the zincmethionine, the copper methionine with the corncob powder with an amount accounting for 20% of the total amount of the corncob powder so as to form a premix A; mixing a premix obtained by premixing the rumen bypass vitamin A, the rumen bypass vitamin D, the rumen bypass vitamin E, the rumen bypass biotin with the corncob powder with an amount accounting for 10% of the total amount of the corncobpowder with the corncob powder with an amount accounting for 20% of the total amount of the corncob powder so as to form a premix B; and mixing the premix A, the premix B and the remaining corncob powder. The feed additive provided by the invention has the following advantages: the level of a limb injury marker can be reduced, and the drylot-fed sheep limb-foot disease is prevented.

Description

technical field [0001] The invention relates to a feed additive capable of preventing and controlling hoof disease in house-feeding sheep and a preparation method thereof. Background technique [0002] At present, house feeding has become the main production method in sheep production. Compared with grazing or semi house feeding, the amount of exercise of house feeding sheep has dropped sharply, the types of rations and feeds are reduced, and the supply of energy, protein and micronutrients is unbalanced. , resulting in hoof disease and even acidosis in house-feeding sheep, manifested as swelling and inflammation of the sheep's joints, joint stiffness in severe cases, unable to stand and walk, crooked hoof clips inside and outside, abnormal split valves, swollen hoof crowns and even hooves. The shell falls off, affecting the feeding and activities of the sheep. In the production, the rams cannot be normally collected and mated, and the ewes cannot reproduce and breastfeed n...

Problems solved by technology

[0002] At present, house feeding has become the main production method in sheep production. Compared with grazing or semi house feeding, the amount of exercise of house feeding sheep has dropped sharply, the types of rations and feeds are reduced, and the supply of energy, protein and micronutrients is unbalanced. , resulting in hoof disease and even acidosis in house-feeding sheep, manifested as swelling and inflammation of the sheep's joints, joint stiffness in severe cases, unable to stand and walk, crooked hoof clips inside and outside, abnormal split valves, swollen hoof crowns and even hooves. The shell falls off, affecting the sheep's feeding and activities

During production, rams cannot be normally collected and mated, and ewes cannot reproduce and breastfeed normally, resulting in large hidden economic losses in breeding, and reducing the comprehensive breeding benefits of house-raising sheep
