Problems solved by technology

However, rapeseed cake contains anti-nutritional factors such as glucosinolate and tannin, and has a large protein molecular weight and high fiber content, which reduces its safety and palatability as feed, and the utilization rate of its nutrients by animals.

Embodiment Construction

[0014] specific implementation plan

[0015] The present invention will be described in further detail below in conjunction with the following specific embodiments:

[0016] Weigh the following raw materials in parts by weight (kg): rapeseed cake 75, wheat bran 11, potato 14, sucrose 5, urea 3, Daqing leaf 2, Radix isatidis 3, salt 2, Acanthopanax polysaccharide, electrolytic multidimensional, Lysine, Lactobacillus acidophilus, Bacillus subtilis, Aspergillus niger, appropriate amount of water;

[0017] The concrete steps of the preparation method of pig feed are as follows:

[0018] (1) Cut the potatoes into small pieces, heat and boil until soft, add sucrose, and mash it into a puree, then add Bacillus subtilis and Aspergillus niger at a ratio of 3:1, stir evenly, and incubate at 30°C for 10 hours to obtain cultivation materials;

[0019] (2) Dissolve urea in an appropriate amount of water, stir well, then fry the rapeseed cake until fragrant, make powder and add the cultu...

Abstract

The invention discloses feed for weaned pigs. The feed is prepared from, by weight parts, 70 to 80 parts of rape seed cakes, 10 to 12 parts of wheat bran, 13 to 15 parts of potatoes, 4 to 5 parts of saccharose, 2 to 3 parts of urea, 1 to 2 parts of folium isatidis, 3 to 4 parts of isatis root, 1 to 2 parts of salt, acanthopanax senticosus polysaccharide, multiplex vitamin of electrolyte, lysine, lactobacillus acidophilus, bacillus subtilis, aspergillus niger and a proper amount of water. According to the feed, the adopted bacillus subtilis and aspergillus niger are adopted to perform mixed fermentation to generate multiple enzymes simultaneously, the shortcoming of monoxenie fermentation is overcome, the content of available nitrogen, the content of small peptide and the content of free amino acid in the rape seed cakes are improved respectively after fermentation, and the content of thioglycoside is reduced. The rape seed cakes are fried and fermented so as to achieve the effect of sterilization and improve the taste of the feed. The fermented isatis root has the effects of being capable of increasing the food intake of the weaned pigs, increasing the daily gain of the weaned pig, improving the utilization rate of the feed, improving the diarrhea of the weaned pig and improving the immunity of the weaned pig.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for weaned piglets and a preparation method thereof. Background technique [0002] Rapeseed cake has a large output in my country, its price is relatively low, and its protein content is above 30%, so it is a protein feed resource with great potential. However, rapeseed cake contains anti-nutritional factors such as glucosinolate and tannin, and has a large protein molecular weight and high fiber content, which reduces its safety and palatability as feed, and the utilization rate of its nutrients by animals. Therefore, reducing the content of anti-nutritional factors in rapeseed cake and improving its nutritional value has become a research hotspot in the feed development industry. Microbial fermentation is the main means to improve the nutritional value of rapeseed cake. Microbial fermentation has the advantages of mild conditions, small loss of dry matter content, and simp...
