Method for producing feed of high-yield dairy cow by using corn straws fermented by Rhodotorula glutinis

Abstract

The invention discloses a method for producing a feed of high-yield dairy cows by using corn straws fermented by Rhodotorula glutinis. The method comprises the following steps of: activating a yeast strain to obtain a corn straw material fermented by the Rhodotorula glutinis by adding aqueous solution, uniformly mixing 40 to 60 weight percent of corn material, 5 to 10 weight percent of cottonseedmeal, 5 to 12 weight percent of distillers dried grains with soluble, 10 to 20 weight percent of concentrated feed and 20 to 30 weight percent of corn straw material fermented by the Rhodotorula glutinis to obtain a mixture, feeding the mixture into a solid fermentation chamber and fermenting, drying a fermented solid feed, crushing, adding a silage into the solid feed, and mixing and stirring uniformly and packaging to obtain the feed of the high-yield dairy cows. In the method, the corn straws are fermented by a biological strain and then are taken as a feed raw material, so that the cost is reduced, the nutrition is rich and easy to absorb, and the method is favorable for improving the milk yield of dairy cows.

Description

[0001] technical field [0002] The invention relates to a method for preparing high-yield dairy cow feed, in particular to a method for producing high-yield dairy cow feed by fermenting corn stalks with red yeast. technical background [0003] With the continuous development of animal husbandry, people's demand for animal products has increased, and small-scale animal product production is far from meeting the growing needs of people. In the past, most animals were raised in free range or outdoors, and most animals were collected freely in the wild. Food, energy and crude protein intake cannot meet growth needs. Recently, with the vigorous development of animal husbandry, the popularity of various premixed feeds and complete feeds, but due to the different digestion and absorption of various nutrients by animals in different growth stages, it is necessary to meet the requirements of different growth stages of animals. Almighty feed, high-yield dairy cow feed has more and m...

[0003] With the continuous development of animal husbandry, people's demand for animal products has increased, and small-scale animal product production is far from meeting the growing needs of people. In the past, most animals were raised in free range or outdoors, and most animals were collected freely in the wild. Food, energy and crude protein intake cannot meet growth needs

Recently, with the vigorous development of animal husbandry, the popularity of various premixed feeds and complete feeds, but due to the different digestion and absorption of various nutrients by animals in different growth stages, it is necessary to meet the requirements of different growth stages of animals. Almighty feed, high-yield dairy cow feed has more and more influence on dairy cows. In the past, high-yield dairy cow feed was processed with dairy basic rations and puffed full-fat soybeans as raw materials, and some were processed with sealed natural fermentation of corn stalks. Such methods have the following disadvantages: the corn stalk crude fiber decomposition ability is poor

Large amount of anaerobic microorganisms can assist digestion and absorption. Crude protein has a small increase ratio and cannot be converted into biological protein. It does not promote digestion in the rumen. Protein and fat are decomposed in the rumen, which cannot guarantee nutrient loss. Low milk production and low energy conversion rate

Processing costs are often higher
