Problems solved by technology

Early weaning of piglets can increase the annual litter size and litter size of sows, reduce the transmission of diseases from sows to piglets, and improve production performance and ketone body quality, but early weaning will cause strong stress to piglets. It often manifests as "early milk syndrome" such as poor appetite, digestive disorders, growth retardation, and diarrhea, which brings huge economic losses to the breeding industry

Abstract

The invention discloses a feed additive for improving the growth performance of a nursery pig. The invention discloses a preparation method of the feed additive for improving the growth performance ofthe nursery pig, wherein the preparation method comprises the following steps: mixing Fuzhuan tea, jujube, star anise and raw ginger, crushing, adjusting the water content, adding a compound enzyme preparation, mixing evenly, carrying out enzymatic hydrolysis, and filtering to obtain a first material and an enzymatic hydrolysate; adding the first material into absolute ethyl alcohol, soaking, andcarrying out ultrasonic assisted reflux extraction to obtain an extract liquid and a filter residue; adding the filter residue to water, soaking, cooking and filtering to obtain a filtrate; mixing the enzymatic hydrolysate, the extract liquid and the filtrate, and drying at low temperature to obtain a second material; adding the second material, excipients and a cladding wall material into water,mixing evenly and spray-drying to obtain the feed additive for improving the growth performance of the nursery pig. The invention discloses an application of the feed additive for improving the growth performance of the nursery pig.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a feed additive for improving the growth performance of nursery pigs and its preparation and application. Background technique [0002] Nursery pigs, commonly known as weaned piglets, have the characteristics of fast growth and development, high susceptibility to diseases, and require careful feeding. Early weaning of piglets can increase the annual litter size and litter size of sows, reduce the transmission of diseases from sows to piglets, and improve production performance and ketone body quality, but early weaning will cause strong stress to piglets. It often manifests as "early milk syndrome" such as poor appetite, digestive disorders, growth retardation, and diarrhea, which brings huge economic losses to the breeding industry. [0003] The physiological basis for this consequence is that piglets' intestinal development, immune system, enzyme system, micro-ecological s...
