Effects of coated cysteamine hydrochloride on muscle fiber characteristics and amino acid composition of finishing pigs.

ABSTRACT:

Objective

This experiment was designed to determine the effects of coated cysteamine hydrochloride (CC) on muscle fiber characteristics, amino acid composition and transporters gene expression in the longissimus dorsi muscle (LDM) of finishing pigs.

Methods

Two hundred and sixteen Duroc/Landrace/Yorkshire cross-bred male finishing pigs were fed with a corn-soybean basal diet supplemented with 0, 70 and 140 mg/kg cysteamine. Each group contained eight replicates of nine pigs per replicate. After 29 days, one pig was randomly selected from each replicate and slaughtered. Blood and LDM samples were collected and analyzed.

Results

The results showed that supplemental dietary CC increased (P < 0.05) the muscle fiber density. And CC supplementation also up-regulated (P < 0.
