Problems solved by technology

Farmers in our country have a long history of using crop straw. Except a small amount is used for gaskets, feeding livestock, and some are used for composting manure, most of them are burned as fuel. A large amount of straw is burned or rotted in the field, causing resources Waste, environmental pollution, affecting traffic

Embodiment 1

[0018] Embodiment 1: 5 parts by weight, crushed into 5 parts of 40 mesh stalks, wherein 19.5 kg of corn stalks, 5.5 kg of peanut seedlings, 5 parts of 25 kg of starch, 2 parts of 10 kg of peanut meal, 0.05 kg of calcium chloride, Mix well to make a mixture. Mix the mixture and water evenly at a ratio of 1:1, put it into a sterilizer and heat it to 121°C, sterilize for 30 minutes, take it out and cool it naturally to obtain a solid medium;

[0019] Add 1.8% of the weight of the solid medium to the yeast activated at 30°C for 4 hours; stir the yeast and the solid medium evenly and ferment at 32°C for 68 hours; after the fermentation is completed, dry at 50°C and dry The product is the final product yeast culture feed additive.

Embodiment 2

[0020] Embodiment 2: 10 kg per part by weight, pulverized into 10 kg of 50 mesh corn stalks, 10 kg of starch, 10 kg of peanut meal, 1 kg of calcium chloride, and mix well. Mix the mixture and water evenly at a ratio of 0.5:1, put it into a sterilizer and heat it to 121°C, sterilize for 30 minutes, take it out and cool it naturally to obtain a solid medium;

[0021] Add 0.5% of the weight of the solid medium to the yeast activated at 25°C for 3 hours; stir the yeast and the solid medium evenly and ferment at 25°C for 72 hours; after the fermentation is completed, dry at 45°C and dry The product is the final product yeast culture feed additive.

Embodiment 3

[0022] Embodiment 3: In parts by weight of 10 kg each, crush 3 parts of 30 kg of 60-mesh corn stalk, 2 parts of 20 kg of starch, 3 parts of 30 kg of peanut meal, and 2 kg of calcium chloride, and mix well. Mix the mixture and water evenly at a ratio of 1:2, put it into a sterilizer, heat it to 121°C, sterilize it for 30 minutes, take it out and cool it naturally to obtain a solid medium;

[0023] Add 3% of the weight of the solid medium to the yeast activated at 28°C for 1 hour; stir the yeast and the solid medium evenly and ferment at 30°C for 36 hours; after the fermentation is completed, dry at 55°C and dry The product is the final product yeast culture feed additive.

Abstract

The invention relates to a process for preparing a feed additive used in livestock and poultry raising industry, in particular to a method for manufacturing a yeast culture additive for livestock and poultry by utilizing crop stalks. The preparation method comprises the following steps: preparation of solid medium: according to the weight portion, crop stalks, starch 1, peanut meal and calcium chloride are evenly mixed to obtain a solid medium mixture; the solid medium mixture is evenly mixed with water according to a certain ratio, put in a sterilizer for sterilization for 30 minutes, and taken out for natural cooling; according to the weight of the solid medium, the yeast is added; the yeast and the solid medium are evenly stirred and subjected to fermentation and drying, and the drying matters are finished products. The invention contains abundant living yeast, amino acids, low molecular peptides and other active compositions, and can improve the producibility of livestock and poultry and improve the health condition of the livestock and poultry; moreover, the novel feed is developed by utilizing abundant stalk resources, which provides a new and effective path for the development of Chinese forage-saving stock raising industry, and the serious environmental pollution caused by the stalk burning is also avoided.

Description

technical field [0001] The invention relates to a processing technology of a feed additive for livestock and poultry breeding, in particular to a method for producing a yeast culture feed additive for livestock and poultry by utilizing crop stalks. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. Farmers in our country have a long history of using crop straw. Except a small amount is used for gaskets, feeding livestock, and some are used for composting manure, most of them are burned as fuel. A large amount of straw is burned or rotted in the field, causing resources Waste, environmental pollution, affect traffic. With the adjustment of agricultural structure, the aggravation of the world's food shortage and the development of grain-saving animal husbandry, it is of practical signi...
