Mouth-open feed for rearing calves and preparation method for mouth-open feed

Abstract

The invention discloses mouth-open feed for rearing calves, belongs to the field of livestock feed, and particularly relates to feed for rearing calves in weaning period. The mouth-open feed is prepared by mixing fermented milk, silage and wheat bran, and comprises the following components in percentage by weight: 20 to 50 percent of fermented milk, 30 to 60 percent of silage and 15 to 25 percent of an additive, wherein the additive is one or a mixture of one or more of wheat bran, corn meal and soybean meal. According to the mouth-open feed for rearing the calves, probiotics are directly added into fresh milk for the calves for fermentation, and the fermented milk is added into the mouth-open feed, and milk flavor has high feeding attraction performance for the weaned calves, so that the palatability is high; the fermented milk is supplemented in a preparation process, so that the calves can be easily transitioned from total milk rearing to solid rearing; due to the addition of the probiotics into the mouth-open feed, the probiotic cultivation in the stomach intestines of the calves is enhanced, the digestive absorption function of the gastrointestinal tracts is improved, and trophic diarherra and bacterial diarherra of the calves can be effectively prevented.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for feeding young calves when they are weaned. Background technique [0002] The feeding of calves is very critical. The growth and development of calves will affect the production performance of cattle in the breeding stage and adult stage. Therefore, the feeding of calves is a crucial link in the process of raising cattle. Under normal circumstances, calves start to be fed open feed about one week after birth. At this time, open feed is fed together with milk. When the intake of open feed reaches about one kilogram, the calf enters the all-solid feed. During the feeding stage, the feed that the calf eats passes through the abomasum, and the nascent rumen does not have the function of digestion and rumination. At this time, due to the immature development of the digestive system, the calf eats solid open feed, which is extremely difficult. It is easy to cause insufficient secretion of digestive...

Problems solved by technology

Under normal circumstances, calves start to be fed open feed about one week after birth. At this time, open feed is fed together with milk. When the intake of open feed reaches about one kilogram, the calf enters the all-solid feed. During the feeding stage, the feed that the calf eats passes through the abomasum, and the nascent rumen does not have the function of digestion and rumination. At this time, due to the immature development of the digestive system, the calf eats solid open feed, which is extremely difficult. It is easy to cause insufficient secretion of digestive enzymes in calves, which reduces the ability to digest nutrients and even causes nutritional diarrhea. In addition, the immune system of calves is not perfect, and the resistance of the gastrointestinal tract to bacteria is also poor. Bacillus and other pathogenic bacteria invade and destroy the beneficial bacteria in the gastrointestinal tract of calves, thus causing gastrointestinal diseases of calves. Failure to prevent and control in time will cause the death of calves
