Study on Muscle Histological Determination of Three Cattle and It’s Correlation with Meat Quality Traits

In order to understand the histological differences between different beef types and their correlation with meat quality traits, six cattle (Holstein cattle and Xilin buffalo) were selected for meat quality traits and histological morphological determination. The results showed that: in terms of muscle fiber diameter, Xilin buffalo >Longlin scalper >Holstein cattle, the density of muscle fibers is the opposite; TypeImuscle fiber proportion ,Xilin buffalo >Holstein cattle >Longlin scalpers showed significant differences among each other (P<0.05); II type A muscle fiber proportion Westwood Xilin buffalo >Longlin scalpers , no significant difference, but ii type A and B ii muscle fiber proportion is put in bigger difference, the alkaline type A muscle fiber ratio is relatively high acid dyeing, ii type B muscle fiber ratio was lower than those of acid dyeing. The diameter of muscle fiber was significantly correlated with marbling, tenderness, pH and intramuscular fat. Type i muscle fiber proportion and marble, intramuscular fat and tender degree of positive correlation, while ii B in proportion to the muscle fibers and pH2 has significant negative correlation.
