Compound pre-mixed material for dairy cows in post-perinatal period and application thereof

Abstract

The invention relates to the technical field of animal feed, in particular to a compound pre-mixed material for dairy cows in the post-perinatal period and application thereof. The compound pre-mixed material consists of iron sulfate, manganese sulfate, zinc sulfate, copper sulfate, 1-percent potassium iodide, 1-percent cobalt sulfate, 1-percent sodium selenite, vitamin A, vitamin D, vitamin E, glucose, coated choline, rumen bypass fat, nicotinic acid, vitamin C, yeast cultures, organic chromium, dihydropyridine, sodium bicarbonate, and a carrier. The compound pre-mixed material can be safelyand conveniently used, obviously improve an effective conception rate and oestrus rate of the dairy cows, reduce non-pregnant days of the dairy cows, shorten a claving interval of the dairy cows, enforce the body recovery of the dairy cows after delivery, lowers a culling ratio of the dairy cows, prolong a use period of the dairy cows, improve a feeding level of the dairy cows, and increase economic benefits of dairy cow farmers; and the compound pre-mixed material also has the advantages of easy source of raw materials, lower cost, obvious effect, easy popularization and wide application prospect, and is specially used for feeding the dairy cows in the post-perinatal period.

Description

technical field [0001] The invention relates to the technical field of animal feed. Background technique [0002] In recent years, my country's dairy industry has made great progress, and the milk production of dairy cows has also been greatly improved, but there are still many problems. In addition to the lack of fine-bred dairy cows, the immediate problem facing us is another problem that needs to be solved urgently. The use life of dairy cows in my country is too short, which seriously restricts the development of my country's dairy industry, and the use life of dairy cows has a direct relationship with the feeding and management of dairy cows during the perinatal period. The perinatal period of dairy cows refers to the period of 2-3 weeks before and after calving of dairy cows. A large number of studies have confirmed that many common diseases of dairy cows are closely related to the feeding management and ration formulation during the perinatal period. Periodic physiolo...

Problems solved by technology

At present, there are many studies on the transition period of dairy cows at home and abroad, but most of the studies focus on the nutritional needs of dairy cows in the pre-perinatal period and the negative energy balance of dairy cows in the post-partum period. There are very few studies on nutritional components such as vitamins and vitamins, and the effects of these nutritional components on the reproductive performance of dairy cows in the postpartum period. Moreover, due to the variety of single additives and the quality is not easy to control, farmers are at a loss, difficult to promote, and the effect is very low. micro
