Processing method for improving digestibility of soybean meal and/or rapeseed meal and/or cottonseed meal

Abstract

The invention discloses a processing method for improving use efficiency of soybean meal and / or rapeseed meal and / or cottonseed meal in a digestion and absorption process of ruminants. The processing method comprises a processing technology, required materials and technological parameters. Through a series of physical and chemical reactions, saccharified soybean meal and / or rapeseed meal and / or cottonseed meal can reach abomasums through rumens of the ruminants, and the protein digestibility of the saccharified soybean meal and / or rapeseed meal and / or cottonseed meal in a whole digestive system of the ruminants is improved, accordingly, protein resources are saved, and are converted into animal products to the greatest extent, the culture benefit of the ruminants is further improved, and remarkable social benefits and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the fields of oil technology and animal nutrition, and in particular relates to oil deep processing and ruminant nutrition. technical background [0002] China is a country that lacks protein resources, and needs to import a large amount of soybeans from abroad every year to meet the needs of domestic feed and breeding industries. In the existing oil processing field, oil plants such as soybean, rapeseed and cottonseed are turned into protein meal such as soybean meal, rapeseed meal and cotton meal after oil extraction, which is used to feed livestock and poultry directly or formulated as feed to feed livestock and poultry. For monogastric livestock and poultry such as pigs and chickens, protein meals such as soybean meal, rapeseed meal, and cotton meal are good protein raw materials. However, for compound gastric ruminants such as cattle and sheep, due to the special compound gastric physiological structure of ruminants, when...

AI Technical Summary

Problems solved by technology

However, for compound gastric ruminants such as cattle and sheep, due to the special compound gastric physiological structure of ruminants, when the protein meal enters the first stomach of ruminants, most of it is degraded by the abundant microorganisms in the first stomach into methane, carbon dioxide and other substances. Excreted by belching, less protein reaches the abomasum, and the protein utilization efficiency of the protein meal is low, which in turn affects the breeding benefits of the farmers

[0003] The academic circle of animal nutrition has theoretically proposed some methods to reduce the degradation rate of protein meal raw materials in the first stomach of ruminants, such as through heating, physical coating, chemical reaction and other methods, but there are various disadvantages in the actual production process and there is no form actual productivity
