Title: Effects of nutrition levels on meat quality traits and heart fatty acid-binding protein gene expression in Guizhou miniature pigs
Abstract: Intramuscular fat content is generally associated with sensory quality and acceptability of fresh pork.This study is conducted with the RT-PCR method to determine effects of nutrition levels on heart fatty acid-binding protein(H-FABP) gene expression and fatty metabolism in muscle in Guizhou miniature pig.A total of 24 Guizhou miniature pigs(male and female half) are randomly divided into four treatment groups,using a 2×2 factorial design to study the effects of dietary energy(DE13.3MJ/kg and DE11.8MJ/kg) and protein(17% and 14%) levels on meat quality traits and H-FABP gene expression in Guizhou miniature pig.The results indicate that the feed intake of 10~20kg Guizhou miniature pig among the four groups is not different(P0.05).The low energy or low protein levels decreases daily gain and feed conversion rate,but the difference is not significant.The H-FABP gene expression(P0.01),intramuscular fat content(P0.05) and muscle tenderness(P0.01) are increased for pigs fed high energy or high protein level.The relationship between H-FABP gene expression and intramuscular fat content is positive(P0.01).It is concluded that H-FABP gene expression and fatty metabolism in muscle are affected by dietary nutritional level.
