Abstract

This study was to evaluate the effects of effects of yeast culture with selenium and germanium on growth performance, fatty acid and amino acid contents in muscle of Yanbian yellow cattle. Twelve 30-month-old Yanbian yellow cattle weighted (351±20) kg were selected and randomly divided into 4 groups with 5 heads per group. Cattle in control group were fed a basal diet, and those in trial groups Ⅰ, Ⅱ and Ⅲ were fed the basal diet supplemented with 0.1%, 0.2% and 0.3% yeast culture with selenium and germanium, respectively. The trial period lasted for 90 d. The results showed that compared with control group:1)average daily gain of trial groups was increased, but there were no significant difference among groups (P>0.05); feed conversion ratio of trial groups Ⅰ and Ⅱ was increased by 18.93% and 22.85%(P<0.05), respectively. 2)Linoleic acid content in muscle of trial groups Ⅰ, Ⅱ and Ⅲ was increased by 9.21% (P<0.05), 11.26% (P<0.05) and 17.06% (P<0.01), respectively; there were no significant differences of contents of other fatty acids among groups (P>0.05). 3)Lysine content in muscle of trial group Ⅲ was increased by 3.81% (P<0.05); alanine content in muscle of trial groups Ⅱ and Ⅲ was increased by 7.81% (P<0.05) and 7.56%(P<0.05), respectively; glutamic acid content in muscle of trial group Ⅱ was increased by 4.98%(P<0.05); there were no significant differences of contents of other amino acids among groups (P>0.05). In conclusion, dietary supplementation of yeast culture with selenium and germanium can increase feed conversion ratio, increase linoleic acid content and decrease satisfied fatty acid/unsatisfied fatty acid in muscle, increase flavor amino acid (lysine, alanine and glutamic acid) contents, and improve beef flavor of Yanbian yellow cattle; the suggested supplemental level of yeast culture with selenium and germanium in diet for Yanbian yellow cattle is 0.2%.

Key words： yeast culture with selenium and germanium; Yanbian yellow cattle; growth performance; fatty acid; amino acid
