Method for making full-time grains of herbivorous animals with crop straws

Abstract

The invention discloses a method for making full-time grains of herbivorous animals with crop straws. The method comprises the following steps: taking the crop straws as main raw materials and performing high-temperature and high-pressure gas explosion on the crop straws, so as to obtain a high-energy straw composite feed semi-finished product; adding corns, bean pulp and accessories that are 10-20%, 5-15% and 2-7% of the weight of the crop straws respectively into the semi-finished product, fully and uniformly stirring the mixture and performing extruding granulation or briquetting, so as to obtain a finished product. According to the method, cell walls of the crop straws are destroyed by adopting a high-temperature and high-pressure gas explosion method, so that neutral detergent fibers in the crop straws can be remarkably decreased, and cellulose and hemicellulose rich in the crop straws can be more effectively utilized; compared with the traditional full-time grains of the herbivorous animals, the full-time grains of the herbivorous animals, which are made by the method disclosed by the invention, is low in cost and high in energy efficiency and has a nutrient structure which is more suitable for ruminants such as cattle, sheep and the like, and grains used for fodder can be greatly decreased.

Description

technical field [0001] The invention relates to a method for preparing whole rations for herbivores with straws in animal husbandry, in particular to a method for making straw-converted high-energy forages that can reduce the neutral detergent fiber of straws and improve the rumen degradation rate of cattle. Background technique [0002] At present, my country's dairy cows, beef cattle, and mutton sheep require a serious shortage of high-quality forage and feed, and the commercialization of herbivorous animal feed is very low. The annual shortage of forage grass and feed in the country is more than 140 million tons. At the same time, due to the excessive grazing of cattle and sheep in the pastoral areas of northern my country, the desertification of the grassland is becoming more and more serious, and the lack of forage seriously restricts the development of herbivorous animal husbandry. my country is a large agricultural country with abundant crop straw resources, the total...

Problems solved by technology

Straw has high crude fiber content, low crude protein, crude fat, and sugar content, low digestibility and poor nutritional value during direct feeding

Generally, some treatment is required before feeding animals. The general treatment methods are mainly divided into physical methods, chemical methods and biological methods. The current various treatment methods cannot greatly improve the comprehensive efficiency of straw feeding.

At the same time, the current production and processing of all kinds of herbivorous animals consume a large amount of grain, and the yield is extremely low; the commercialization of various herbivorous animal forage feed is extremely low, which greatly hinders the development of various herbivorous livestock breeding

[0003] As the whole diet of animals, crop straw feed has the problem that it is not easy to preserve. There are conditions in the feed that promote the occurrence of pests and provide favorable conditions for the breeding of pests. The pests living in the feed for a long time will affect the feed to varying degrees. The main hazards are: 1 ) Insect feces, insect corpses, and odorous liquid secreted by some pests pollute feed and raw materials, resulting in a reduction in feed quality; 2) Insect spinning and metabolizing water can cause feed agglomeration, cause feed mildew, and shorten the shelf life of feed; 3 ) Some pests can produce toxins, affecting animal health; 4) After the feed is eaten by pests, the number is reduced; 5) Acting as a medium for the transmission of pathogenic microorganisms
