A Note on Fatty Acids Profile of Meat from Broiler Chickens Supplemented with Inorganic or Organic Selenium

Table 4

Enzymes indexes of fatty acid metabolism estimated on the basis of fatty acid composition of Pectoralis and Gastrocnemius muscles of chickens supplemented in diet with inorganic (Se-Na) or organic (Se-Met) selenium.

Enzyme indexes	Pectoralis muscle (Pe)			Gastrocnemius muscle (G)			Main effects
	Control	Se-Na	Se-Met	Control	Se-Na	Se-Met	Muscle (M)	Diet (D)	M D
Δ-9 desaturase
16:1/16:0
18:1/18:0
16:1 + 18:1/16:0 + 18:0
Δ-5 + Δ-6 desaturases
Elongase 18:0/16:0
Thioesterase 16:0/14:0

Results are means ± SEM. Δ-9 desaturase indexes, Δ-5 + Δ-6 desaturases, elongase, and thioesterase indexes were calculated according to [14, 15].
