Chinese herbal medicine additive for piglet feed and preparation method thereof

Abstract

A Chinese herbal medicine additive for a piglet feed and a preparation method thereof. The additive is composed of root of Chinese pulsatilla, Coptis chinensis, Radix Astragali, purslane, Cortex Phellodendri, scorched hawthorn fruit, dried tangerine peel, radix paeoniae alba,Angelica sinensis and licorice. The preparation method is as below: crushing the above Chinese herbal medicines; weighing, soaking the medicines with water and boiling with strong fire; insulating for 30-60min with slow fire; cooling and filtrating with eight layers of gauze; collecting a filtrate; adding sugar, lactobacillus and saccharomycetes, and fermenting to obtain a fermentation broth; and adding corn, wheat bran, soybean meal into the fermentation broth for feeding the piglets directly. According to the invention, growth and reproduction of beneficial bacteria in intestines are conducive to absorption, digestion and utilization of nutrients, so as to promote healthy growth of piglets, and effectively control diarrhea and growth arrest. Effective components of the Chinese herbal medicines in the additive will increase exponentially through microbial fermentation; and the additive can reduce drug resistance of animal and residues in animal bodies, so as to avoid passive medication by human and improve food safety.

Description

technical field [0001] The invention relates to a Chinese herbal medicine additive for piglet feed, which belongs to the field of feed and is suitable for the Chinese herbal medicine additive for piglet feed of 1-30Kg just after birth Background technique [0002] The physiological characteristics of piglets are intolerance to low temperature, imperfect digestion, rapid growth and development, and lack of innate immunity. As we all know, piglets grow fast because of their vigorous material metabolism, especially protein metabolism and calcium and phosphorus metabolism, which are higher than those of adult pigs many. At the age of 20 days after birth, the protein deposited per kilogram of body weight is equivalent to 30 to 35 times that of adult pigs, and the net metabolic energy required per kilogram of body weight is 3 times that of adult pigs. The weight of piglets at birth is generally 1-1.5 kg. After 2 months of feeding, the weight can reach 15-20 kg, an increase of mor...

Problems solved by technology

[0003] In recent years, most pig farms have adopted the method of early weaning. Early weaning has the advantages of reducing feed-to-meat ratio and improving economic benefits. When using the current piglet feed or additives, there are generally poor palatability and low digestibility, which can easily cause piglets to not want to eat, or even growth inhibition after eating, diarrhea and death.

[0004] Most of the current pig feed additives are mainly trace minerals and hormones, and the promotion of pig growth mainly depends on the effect of hormones, and they are general-purpose additives. Chinese herbal medicine additives after microbial fermentation of Chinese herbal medicines have not been reported.
