Excessive abdominal fat content(AFC) has negative impacts on feed efficiency and carcass *** AFC,intramuscular fat content(IMFC) could be a favorable trait,which has a positive impact on meat *** meet consumers’ needs,a long-term goal of broiler breeders is to decrease AFC and improve the IMFC *** current study was designed to investigate the relationship between AFC and IMFC and to compare IMFC,including the pectoral major muscle fat content(PIMFC) and intramuscular fat content of leg muscle(LIMFC),between two broiler lines divergently selected for abdominal fat percentage over 17 *** results showed that there was a significant difference in PIMFC and LIMFC between the two lines in all five generation populations *** birds in the lean line had significantly lower AFC but higher PIMFC and LIMFC than the birds in the fat *** also detected differences in the liver fat content(LFC) between the two lines and the results showed that birds in the fat line had significant higher LFC than birds in the lean *** results indicated that a desirable broiler line with higher IMFC but lower AFC could be obtained by genetic selection.

Background Excessive backfat deposition lowering carcass grade is a major concern in the pig industry,especially in most breeds of obese type *** mechanisms involved in adipogenesis and fat accumulation in pigs remain *** 2-hydroxyisobutyrylation(Khib),is a novel protein post-translational modification(PTM),which play an important role in transcription,energy metabolism and metastasis of cancer cells,but its role in adipogenesis and fat accumulation has not been *** In this study,we first analyzed the modification levels of acetylation(Kac),Khib,crotonylation(Kcr)and succinylation(Ksu)of fibro-adipogenic progenitors(FAPs),myogenic precursors(Myo)and mesenchymal stem cells(MSCs)with varied differentiation potential,and found that only Khib modification in FAPs was significantly higher than that in ***,in parallel with its regulatory enzymes lysine acetyltransferase 5(KAT5)and histone deacetylase 2(HDAC2)protein levels,the Khib levels increased quadratically(Pfat accumulation by comparing Khib levels in FAPs and backfat tissues both derived from obese-type pigs(Laiwu pigs)and lean-type pigs(Duroc pigs),***,the expression patterns of KAT5 and HDAC2 matched well to the degree of backfat accumulation in obese-and lean-type *** From the perspective of protein translational modification,we are the first to reveal the role of Khib in adipogenesis and fat deposition in pigs,and provided new clues for the improvement of fat accumulation and distribution as expected via genetic selection and nutritional strategy in obese-type pigs.
