The objective of the present study(2009) was to investigate the effects of dietary lysine and GLA level on the growth performance, carcass and meat quality parameters in finishing pigs. Regarding the growth performance, final weight and average daily gain were higher(P<0.01) in lysine 0.75% level than in lysine 0.45% level. Feed conversion ratio was higher in lysine 0.45% level than in lysine 0.75% level(P<0.01). Carcass weight, dressing, carcass grade were no effect of lysine level and GLA level. Crude fat was higher in lysine 0.45% level than in lysine 0.75% level(P<0.01).
Objective of this genomic research was to obtain the effects of dietary fat sources namely tallow, soybean oil, olive oil and coconut oil on the growth performance, meat quality and gene expression in growth-finishing pigs. In meat quality, crude protein was higher in the beef tallow group than in the soybean oil group. Myristic and palmitoleic acids were higher in the coconut oil group, palmitic acid was less in the olive oil group, oleic acid was higher in the olive oil group, linoleic and linolenic acids were higher in the beef tallow and soybean oil groups, UFA and MUFA were higher in the olive oil group. Also, PPP1CB and PRKAR2A genes were influenced by dietary fat types in barrow. The PRKAR2A gene hasa high gene expression pattern in beef tallow and olive oil group. However, PPP1CB gene has a gene expression significantly and differentially in four dietary oil group, and has the highest gene expression in olive oil group. It can be said that the types of fat affected the growing performance, fatty acid composition and insulin signaling related genes in the longissimus dorsi muscle.
