Feed used for cows at pregnancy period and capable of improving survival rate of embryos and promoting reproductive health of cows and preparation method of feed

Abstract

The invention discloses feed used for cows at a pregnancy period and capable of improving the survival rate of embryos and promoting reproductive health of the cows and a preparation method of the feed. By virtue of the feed disclosed by the invention, the survival rate of the embryos can be improved, accidental abortion of the cows at the pregnancy period is prevented, the birth weight of calves is improved, the birth death rate of the calves is reduced and the growth performance of the calves after birth is enhanced; the feed contains diversified nutrients, has sufficient energy and can meet nutritional requirements of the cows and the calves; and semen cuscutae, bighead atractylodes rhizomes and radix scutellariae are matched so that the reproductive function of the cows can also be improved and the reproductive health is facilitated.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a feed for pregnant cows which improves the survival rate of embryos and promotes the reproductive health of cows and a preparation method thereof. Background technique [0002] In recent years, my country's demand for beef, especially high-quality beef, has been increasing day by day, and the price of beef has continued to rise. The beef cattle market has been in short supply. At one time, horse meat was used instead of beef to ease market demand. The stock of beef cattle and cows in southern my country accounts for 37% of the country. The stock of beef cattle is relatively large, and the demand for cattle feed is huge. Over the years, China has been committed to the development and utilization of grasslands and grass slopes in the south, but the industrialization progress is slow. The main reason is that the cost of cultivating forage is greater than the income of lives...

Problems solved by technology

In the article "Using Sugarcane Tips (Leaves) as Feed for Cattle", the author used sugarcane tips (leaves) as feed raw materials, and carried out technical research on sugarcane tips (leaves) through micro-storage, ammoniation, and mixing with molasses bagasse. Although this method can improve the digestibility and nutritional value of sugarcane tips (leaves) to a certain extent, it still has the following shortcomings: First, the protein content in the feed is low, and protein is the basic structure of cells. Organic matter is the main bearer of life activities. All important components of the body need the participation of protein. The lack of protein directly leads to problems such as thin body, poor growth and development, and decreased meat production. Second, the feed preparation process is relatively old. The innovation and superiority of the process are not outstanding enough, which leads to the inability to give full play to the nutritional value of the feed, which is not conducive to promoting the sustainable development of cattle breeding; the third is that in the process of feed processing, the lack of auxiliary materials is not conducive to the adjustment of cattle. Physiological function and development level, and cannot improve the taste, flavor and palatability of the feed, leading to serious problems such as weakening of the physiological regulation function of cattle and loss of appetite
