Effects of lecithin on the enzyme activity in serum and liver of broilers at 21 and 42 days ¹.

Period	Items	Unit	Control	Treatment	SEM	p-Value
21 days(serum)	LPL	U/mL	1.53	1.64	0.07	0.419
	HL	U/mL	2.34	1.53	0.16	0.008
	GE	U/mL	3.96	3.18	0.17	0.018
21 days (liver)	HL	U/mL	0.48	0.55	0.03	0.228
42 days(serum)	LPL	U/mL	1.17	1.77	0.02	0.176
	HL	U/mL	1.69	1.96	0.11	0.213
	GE	U/mL	2.87	3.78	0.24	0.054

¹ LPL means lipoprotein lipase and HL means hepatic lipase. GE means general esterase activity, which was calculated as the sum of LPL and HL.
