Analysis of variability of plasma leptin and lipids concentration in relations to glycolytic potential, intramuscular fat and meat quality in P76 pigs

Résumé

The aim of the study was the analyse of the variability and relationship between plasma leptin and lipids concentration, glycolytic potential, intramuscular fat and meat quality in P76-PenArLan hybrids pigs. The research was carried out on 30 pigs (18 boars and 12 gilts). In blood plasma, taken in vivo, leptin, triglycerides, total and HDL cholesterol were measured. Slaughter value of carcass was evaluated by CGM apparatus. On the basis of pH value, meat colour and natural drip loss, meat quality was estimated. Intramuscular fat and glycolytic potential was also determined. Obtained results showed a signifi cant inversely relationship between: a. plasma leptin level and backfat thickness and b. between intramuscular fat and glycolytic potential in muscle. Cluster analysis showed that studied pigs had been divided into three metabolic type groups differed signifi cantly in plasma leptin, triglycerides, total and LDL cholesterol concentration, backfat thickness, glycolytic potential and drip loss.
