Problems solved by technology

[0004] The initial discovery of β-glucan was isolated from the bacterial cell wall. The purity of the β-glucan isolated from the bacterial cell wall is generally only about 20%, and the isolated β-glucan has a large molecular weight and is insoluble. In water, it is greatly limited in application

Embodiment Construction

[0019] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0020] 1. Experimental design and diet

[0021] This experiment adopts a single factor experimental design, with 4 treatments, 6 repetitions for each treatment, and 4 pigs for each repetition. The experimental basal diet was based on the corn-soybean meal type ration formulated by NRC (2012). Example 1 group was fed basal diet+50mg / kg β-glucan, and Example 2 group was basal diet+100mg / kg β-glucan. For polysaccharides, the group in Example 3 was basal diet + 200 mg / kg β-glucan, and the group in Example 4 was fed the basal diet without adding β-glucan.

[0022] 2. Experimental animals and feeding management

[0023] The experiment was carried out at the Danling pig farm in Meishan, Sichuan. 96 healthy DLY pigs of about 20 kg were selected and rand...

Abstract

The invention relates to the technical field of animal feed, in particular to beta-glucan (salecan) capable of increasing the fattening pig growth performance and improving the meat quality and application thereof in fattening pig feed. The beta-glucan capable of increasing the fattening pig growth performance and improving the meat quality is salecan and a fermentation product of Agrobacterium sp. ZX09, and the adding amount of the beta-glucan (salecan) in the fattening pig feed is 50-200 mg / kg. The beta-glucan has the advantages that the average daily gain and nutrient digestibility of fattening pigs are increased, intestinal floras are improved, the water holding capacity, inosinic acid in meat and unsaturated fatty acid are improved, and the flavor of the meat is significantly improved.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a beta-glucan (salecan) capable of improving the growth performance and meat quality of fattening pigs and its application in rations for growing and finishing pigs. Background technique [0002] Subtherapeutic levels of antibiotic feed additives have been widely used in pig feeds since the 1950s to improve growth rate and feed efficiency, and to maintain pig performance in the presence of subclinical disease. Antibiotic feed additives have a good effect in the application of fattening pig diets. Fifteen years ago, Zimmerman (1986) summarized data from 239 independent experiments and reports showing that the addition of antibiotic feed additives to the pre-feed can improve its performance, which can increase growth rate and feed conversion rate by an average of 15% and 15%, respectively. 6%; for late growing and finishing pigs, antibiotic feed additives can increase growth r...
