Feeding management method for cows in dry period

Abstract

The invention discloses a feeding management method for cows in the dry period. In the method, quick, safe and effective ablactation is carried out through intervention in the aspects of changing theration formula, limiting cows' drinking, increasing exercise, massaging breasts and the like according to the physiological characteristics of the cows in the dry period, so that the physique of the cows is recovered, and nutrients are accumulated; the ration proportion is properly adjusted according to the poor digestion function of the cows in the dry period, the calcium and phosphorus content is properly increased and intramuscular injection of vitamin D3 is performed to prevent postpartum calcium-deficiency paralysis, nicotinic acid and progesterone prevention is performed in advance to prevent postpartum ketosis and retained fetal membranes, lactiferous ducts are dredged with Chinese medicine juice before delivery to make preparation for lactation and prevent mastitis, and the energylevel of feed and the fatness of the cows are controlled in the whole dry period to prevent the cows from constipation and dystocia. The breeding method is scientific, reasonable and low in cost, themorbidity of the cows in the dry period is effectively avoided, mammary glands are allowed to rest and restore to accumulate nutrients, and the purposes of good health, high yield and stable yield ofthe cows are achieved.

Description

technical field [0001] The invention relates to the technical field of dairy cow breeding, in particular to a method for feeding and managing dairy cows during the dry period. Background technique [0002] The dry period is the period from the end of gestation when cows stop milking until calving. The lactation period of dairy cows is as long as 305 days. Cows have experienced long-term lactation and pregnancy, and the body needs a period of time to rest and recover. In addition, after the cow is pregnant, especially in the late pregnancy, the fetus grows rapidly, especially the increase in fetal weight is mostly in the middle and late pregnancy, and the cow can secrete more milk after calving for Lactating calves need a lot of nutrients to meet the needs of fetal growth and milk production, so cows must stop milking and enter the dry period. Scientific and reasonable dry milk can ensure the normal growth and development of the fetus, and can also allow the mammary gland t...

Problems solved by technology

In actual production, most dairy farmers have improper feeding and management of dairy cows during the dry period, and comprehensive mastitis prevention and control measures are not in place, which often cause frequent postpartum diseases and mastitis, resulting in serious economic losses. Therefore, more sophisticated methods are needed. A set of feeding and nursing methods is aimed at the feeding of dairy cows in the dry period, reducing economic losses and scientific feeding
