Method for reducing death rate of lambs in winter

Abstract

The invention discloses a method for reducing the death rate of lambs in winter. The method is characterized by comprising the following steps: (1) feeding ewes in winter and preparing concentrated feed for feeding the ewes; feeding the ewes with the concentrated feed twice every day and feeding 270g to 320g of the concentrated feed once, so as to increase nutrient absorption of the ewes; (2) carrying out sterilization treatment; carrying out the sterilization treatment on a sheep house and sheep dung by utilizing 160ppm sodium hypochlorite and bleaching powder at the weight ratio of 1 to 4; (3) breeding born lambs; when the ewes give birth to the lambs, transferring the ewes to a delivering room; after the lambs are born, wiping the lambs with 75% alcohol to carry out sterilization and transferring the lambs to a breeding room for breeding; before the lambs are taken away from the breeding room, reducing a temperature through two phases so as to enable the lambs to be adapted to an external environment better; and (4) carrying out final-period management, regulating the inner temperature of the sheep house and cleaning and sterilizing the sheep house at a fixed period.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a method for reducing the mortality rate of lambs in winter. Background technique [0002] In winter, the temperature is low, cold and dry, and the selection of ewe breeding in winter will greatly affect the survival rate of lambs. The ewes themselves are thin in winter, and hay is used as the staple food for ewes, which lacks nutrients. Without additional nutritional feed supplements, ewes will be thin and malnourished, resulting in insufficient absorption of lamb placenta nutrients, and lambs are prone to Congenital diseases; at the same time, ewes will also suffer from lack of milk and less milk. Lambs do not have enough breast milk to obtain immunoglobulin or maternal antibodies. After birth, lambs have low immunity and are likely to cause disease and death. In simple sheep breeding sheds, foreign harmful germs are easy to spread to the breeding sheds, a...

Problems solved by technology

[0003] The present invention aims at the existing problems: in the feeding of ewes, ewes breed in winter and are in the period of withered grass. The main feed is hay, and the feed lacks necessary nutrients. In the absence of reasonable concentrated feed, ewes will appear nutritionally Poor, lamb placental nutrient absorption is insufficient, ewes have milk shortage and weaning phenomenon, lambs cannot obtain immunoglobulin or maternal antibodies from breast milk, lambs have low immunity, and it is easy to cause disease and death
