Extract

The combination of genotypes (100% stress negative) and other treatments, especially nutritional, can give good results in achieving fast lean growth with good meat quality (Cameron et al., 1998). The reasons of negative relationships among growth performance and meat and eating quality traits are not completely clear. Increased rate of muscle growth can lead to changes in histochemical muscle properties such as an increase in the proportion of type IIB fibres which can result in less tender and less red meat (Warriss, 2000). In terms of a nutritional treatment, which can be beneficial to improving meat and eating quality, special attention in recent years has been paid to (CLA). Therefore, the aim of this study was to determine the influence of dietary CLA supplementation on histochemical profile of m. longissimus dorsi from pigs slaughter at heavier weights (129.9 kg).
