Effects of compensatory growth on some body component weights and on carcass and noncarcass composition of growing lambs

Article Abstract:

Results of an experiment on lambs indicated that weight loss during periods of feed shortage is mainly due to loss in visceral organ weight and this is easily regained during realimentation. 106 lambs were allotted to one of the six pre-determined feed intake levels and weight of visceral organs. Carcass and non carcass composition of calves was assessed to identify the effects of change in feed intake levels and compensatory growth on alteration in weight of organs and noncarcass and carcass composition. Lambs undergoing compensatory growth showed higher feed efficiency and leaner carcasses.

Volatile compound content and fatty acid composition of pork as influenced by linoleic acid content of the diet

Article Abstract:

The concentration of dietary linoleic acid (C18:2) influenced the fatty acid composition of subcutaneous fat and lean tissue in pigs. Increasing linoleic acid concentrations increased the levels of C18:2, C20:2 and C20:3 fatty acids in fat and C18:2 in lean meat while decreasing C18:3 and C24:0 fatty acids in lean meat. The high level of C18:2 raised the concentrations of several volatile compounds including pentanal, hexanal, trans-2-heptanal, 2-pentyl furan and 2-ethyl-1-hexanol in pork. However, no effects on sensory evaluation were detected.
