Effect of vitamin E and phytogenic feed additives on perfomance, blood constituents and antioxidative properties of broiler chicks [electronic resouce].

Includes references.

Two hundred and sixteen, 7 day old unsexed Hubbard broiler chicks were divided randomly into nine treatments. Each treatment had 3 replicates with 8 chicks each. Chicks of each replicate were housed in cages (100X50X50 cm). All chicks received basal diets had 22.5 and 17.54% crude protein and 3102 and 3099 kcal ME /kg diet for the starter and grower diet, respectively. Chicks in group 1 were fed on basal diets without any addition (control); chicks in other groups fed basal diets supplemented with V.E 200 mg/kg feed; Rosemary 1.5, 3 or 9 g/kg feed, Saffron15or 30 ppm/kg feed, Rosemary- Saffron (0.75g +7.5 ppm) / kg feed and Rosemary- Saffron (1.5g +15ppm)/kg feed for treatments 2, 3, 4, 5, 6, 7, 8 and 9, respectively. Results of body weight and body weight gain at 42 day of age had a significantly (P?0.05) decrease of broilers fed Rosemary 9.0 g/kg than other treatments. Feed consumption during 1- 6 week interval was significantly (P≤0.05) decrease for broilers fed Rosemary 9.0 g/kg, but Rosemary 9.0 g/kg feed had the worst conversion ration. No significant effects were observed in Carcass Characteristics and meat chemical analyses except abdominal fat. Key words: Phytogenic, Vitamin E, Growth, Blood, Antioxidative Properties and Broiler.
