Abstract
The aim of this study was the determination of muscle and plasma profiles of free fatty acids and of triacylglycerols incorporated fatty acids in fed and underfed Boer goat bucks. This trial with 15 Boer goat bucks weighting 28 Kg had a duration of 30 days during which the 2 distinctive groups of animals were organised (control group—C—fed ad libitum and a restricted group—R—fed 80% of energetic maintenance needs). The content of blood and muscle free fatty acids in the fraction of triacylglycerols was studied. % C16:0 as free fatty acid in the plasma suffered a significant effect of undernutrition (increase) and C18:1 showed a relative decrease in muscle fatty acid incorporated in triacylglycerols in underfed goats. C18:2 revealed a relative increase in muscle fatty acid incorporated in triacylglycerols and a relative decrease in free fatty acid in the plasma in the restricted group.
