Disease-resistant nursery piglet feed without antibiotics and preparation method and application thereof

Abstract

The invention discloses a disease-resistant nursery piglet feed without antibiotics. The disease-resistant nursery piglet feed is prepared from the following components in parts by weight: 0.5 to 1.0 part of conjugated linoleic acid, 0.2 to 0.8 part of acidifying agent special for sows, 0.01 to 0.05 part of chitosan oligosaccharide, 0.01 to 0.05 part of cinnamyl aldehyde, 0.01 to 0.05 part of curcumin, 0.02 to 0.08 part of tannic acid, 0.1 to 0.5 part of nucleotide, 0.01 to 0.08 part of microecological preparation, 0.01 to 0.05 part of phytase, 0.01 to 0.05 part of compound enzyme and the like, and is free from antibiotics. The invention further provides a preparation method for the feed. The feed has the effects of improving disease resistance and survival rate of nursery piglets, and avoiding drug resistance risk caused by use of antibiotics.

Description

technical field [0001] The invention belongs to the field of animal feed, and in particular relates to an antibiotic-free feed for disease-resistant nursery piglets and a preparation method and application thereof. Background technique [0002] Since the 1960s, China's breeding technology level is relatively backward and the breeding environment is relatively poor. Antibiotics are used as growth promoters (AGP) in animal breeding to maintain animal intestinal health and improve animal production performance, and have achieved good results. The effect has greatly promoted the development of the aquaculture industry. However, practice has shown that the continuous large-scale feeding of AGP and the resulting drug resistance of bacteria, the deterioration of the use of antibiotics, drug residues in animal products and their side effects are becoming more and more serious. Now, with growing concerns about the possible resistance of pathogenic microorganisms to antibiotics and t...

Problems solved by technology

Adding probiotics and excipients to improve immunity is a common way to replace antibiotics to make piglet feed. There are also some studies that add certain plant extracts to feed to improve disease resistance. However, due to the development of drug-resistant bacteria, these antibiotic-free feed Piglet feed can no longer solve the problems of weaning piglets prone to stress, diarrhea, low immunity and inhibited growth potential
