Effects of body weight on some plasma parameters of pigs from the Alentejano breed

Abstract

This work has evaluated the influence of body weight (BW) on some plasma parameters of Alentejano pigs. Thirty castrated
Alentejano pigs (~35 kg BW) were allocated in individual pens and fed a commercial diet (0.85x ad libitum). The pigs were slaughtered in groups (n=5) with an average BW of 42.2, 70.9, 80.2, 90.1, 100.5, and 110.2 kg. Plasma samples obtained at
slaughter were analysed. Glucose and triacylglycerol levels decreased (P?0.05) with increasing BW, suggesting that during
growth Alentejano pigs increased the use of glucose and triacylglycerols as energy and substrate for fat synthesis and
deposition. Total cholesterol increased (P?0.05) with BW, due to an increase (P?0.05) in the low-density lipoprotein (LDL) cholesterol level, following the trends reported in ageing mammals. The Alentejano pig, with a high lipogenic activity, could be a valuable model for studies of the cholesterol metabolism.
