Radix astragali seu hedysari and rhizoma zingiberis composite extract as well as preparation method and application thereof

Abstract

The invention provides radix astragali seu hedysari and rhizoma zingiberis composite extract as well as a preparation method and application thereof. The radix astragali seu hedysari and rhizoma zingiberis composite extract is prepared from the following components in parts by weight: 30 to 45 parts of rhizoma zingiberis, 20 to 35 parts of rhizomae pinelliae, 8 to 15 parts of radix astragali seu hedysari, 6 to 12 parts of white paeony roots, 10 to 20 parts of fenugreek seeds, 6 to 8 parts of fructus mume, 12 to 20 parts of fructus evodiae and 5 to 8 parts of liquorice roots. The prepared radixastragali seu hedysari and rhizoma zingiberis composite extract is dispersed and added into feed according to the amount of 0.5 to 1 percent of the mass of piglet feed and is used for feeding weaningpiglets; the radix astragali seu hedysari and rhizoma zingiberis composite extract can be used for preventing and controlling the stress of the weaning piglets to improve the anti-stress capability of the weaning piglets and improve growth conditions of the weaning piglets.

Description

technical field [0001] The invention belongs to the field of veterinary preparations, and in particular relates to a composite extract of astragalus and dried ginger, a preparation method and application thereof. Background technique [0002] With the intensive and large-scale development of the pig industry, early weaning of piglets has become a common method in pig production. However, due to the immature digestive system of early weaned piglets, it is difficult to withstand the transition from breast milk to feed, and piglets will experience great biological stress, causing a series of neuroendocrine changes, leading to changes in gastrointestinal physiology, microbial flora and immunity. Changes have brought a series of adverse effects on the growth and development of piglets, mainly manifested as diarrhea, loss of appetite, slow growth or even stagnation, irritability, increased aggressiveness, etc., which affect the growth of piglets and even cause piglets to die.

Problems solved by technology

However, due to the immature digestive system of early weaned piglets, it is difficult to withstand the transition from breast milk to feed, and piglets will experience great biological stress, causing a series of neuroendocrine changes, leading to changes in gastrointestinal physiology, microbial flora and immunity. Changes have brought a series of adverse effects on the growth and development of piglets, mainly manifested as diarrhea, loss of appetite, slow growth or even stagnation, irritability, increased aggressiveness, etc., which affect the growth of piglets and even cause piglets to die. One of the important problems faced in pig production

[0003] At present, most farmers use additives such as antibiotics, probiotics, oligosaccharides and enzyme preparations to feed for the stress of piglets during weaning. growth rate, but with the addition of antibiotics, there will be problems such as drug residues and drug resistance, and the dosage is gradually limited
