TI - Effect of lasalocid supplementation on some metabolic and endocrine parameters in turkey poults KW - Turkey KW - Poultry KW - Feed utilization efficiency KW - lasalocid N1 - Includes references N2 - Lasalocid, a carboxylic ionophore antibiotic, is used frequently in poultry feeds as a coccidiostat, however the present study centered on its role as growth promoter and in steroidogenesis. llwenty turkey poults, 60 days old, were allocated randomly in two equal groups; control group and lasalocid supplemented group (120 r;pm). Blood samples were collected at three weeks interval, till the 23' week, for determination of serum biochemIcal parameters (glucose, triglycerides cholesterol, total proteins and albumin), and gonadal steroids (namely estradiol and progesterone). Body weight and feed consumption were also determined weekly to calculate feed efficiency. Carcass weight and dressing % were also recorded. The results revealed that lasalocid supplementation did not result in any significant change in glucose, triglycerides and cholesterol concentrations among the two experimental groups, however, the total protein and albumin concentrations were significantly increased in lasalocid supplemented group UR - http://nile.enal.sci.eg/EALE/2006/AVMJ/5206/109/274.pdf ER -
