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
Bring unnecessary losses to the majority of farmers

Abstract

The invention provides calf feed and a preparation method thereof and belongs to the field of feed preparation. The calf feed comprises, by weight, 50-70 parts of broussonetia papyrifera leaf, 20-50 parts of corn, 5-10 parts of molasses and 0.5-2 parts of bacterial strains. The preparation method includes steps of raw material treatment and fermentation. The broussonetia papyrifera leaf is adopted as a main raw material to prepare the calf feed, and molasses and corn are added, so that the calf feed is comprehensive and balanced in nutrition; through the method and fermentation treatment of the bacterial strains, the calf feed serving as starter feed is high in palatability and excellent in intake inducing performance, and digestion and absorption capability of calves after the early stage of ablactation can be enhanced; candida tropicalis, lactobacillus and bacillus subtilis are selected as the bacterial strains, so that concentration of volatile fatty acids like acetic acid, propanoic acid and butyric acid in rumens of the calves can be increased, rumen development of the calves can be promoted, and capability in digestion and absorption of the feed can be improved.

Description

technical field [0001] The invention belongs to the technical field of feed processing, in particular to a calf feed and a preparation method thereof. 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 insufficien...
