Premix feed for butcher cow in latter half of gestation and feeding method thereof

Abstract

The invention discloses a premix feed for a butcher cow in latter half of gestation. The premix feed is formed by mixing, by weight, 15%-25% of vitamin E with the content of 50%, 1-5 parts of vitamin D3 (500,000 international units / g), 5-10 parts of vitamin A (500,000 international units / g), 5-10 parts of ferrous sulfate, 1-5 parts of tribasic copper chloride, 1-5 parts of zinc sulfate, 5-15 parts of magnesium sulfate, 3-10 parts of manganese sulfate, 5-10 parts of sodium sulfate, 1-10 parts of cobalt premix containing 1% of cobalt, 1-10 parts of iodine premix containing 5% of iodine, 20-30 parts of selenium premix containing 1% of selenium, 1-5 parts of chromium diluent containing 0.62% of chromium, 600-800 parts of ion carrier and 150-250 parts of premix feed carrier. The premix feed is added into feed for the butcher cow in the latter half of gestation, feed intake of the cow is not affected, postpartum paralysis, retained placenta, failure to observe oestrus, infertility and abortion can be prevented simultaneously, the lactation quality and postpartum reproductive performance of the cow are improved, and the symptoms such as calf diarrhea and malnutrition are prevented.

Description

technical field [0001] The invention relates to a premixed material for beef cows, in particular to a premixed material for beef cows in late pregnancy. Background technique [0002] The late pregnancy of beef cows, that is, from July to parturition, is very important for the health, lactation quality and reproduction of postpartum cows. Many metabolic diseases, such as postpartum paralysis, retained placenta, metritis, etc., mainly occur during this period. Although the time of this stage is very short, it is crucial to the reproduction of postpartum cows and the improvement of the survival rate of calves. [0003] Clinical postpartum paralysis occurs in 8% of cattle in the United States every year, and the loss caused by each case is 300 US dollars. The proportion of subclinical hypocalcemia in cows with two or more births is 30% every year, and the loss caused by each case is $125 (Garrett R. Oetzel, 2014). Recent studies have shown that hypocalcemia at calving can cau...

Problems solved by technology

Due to the limitations of the research objects, methods and technical means, there are still many problems in the production of licking bricks, such as single product variety, unqualified product quality, poor physical properties, easy moisture absorption, lack of unified quality evaluation standards, and poor palatability of animals. , low production efficiency and high production cost; in addition, the mechanism of promoting the production performance of ruminants is not very clear, and the research results are also inconsistent. Therefore, it has seriously hindered the promotion and application of compound nutrient licking bricks
