Effects of Avilamycin, FormycinGold and FYTO-MIX on Serum Lipid Concentrations of Young Broilers
This experiment was conducted for comparison the effect of some feed growth promoter additives on serum lipid concentrations of 21 days old broiler chickens. Based a randomized completely design, 300 days old Ross 308 broilers were distributed into 20 floor pens and reared for 21 days. A basal diet was formulated according to NRC recommendations for starter (1-21 days) period. The basal diet was also supplemented with antibiotic (Avilamycin), a commercial composition (FormycinGold), herbal additive (FYTO-MIX) and mixture of FormycinGold plus FYTO-MIX, resulting 5 dietary treatments were prepared including control group. Each dietary treatment was fed ad-libitum to 4 replicates group of 15 birds at the beginning of rearing period. Serum cholesterol and Low Density Lipoprotein (LDL) levels of broiler were fed FYTO-MIX and FormycinGold plus FYTO-MIX was significantly lower than control group (p<0.05). The higher High Density Lipoprotein (HDL) concentration was recorded for birds fed diet supplemented with FormycinGold, FYTO-MIX and FormycinGold plus FYTO-MIX. None of the treatments had significant effect on triglycerides and Very Low Density Lipoprotein (VLDL) levels.
