| Marigold flower extract, a natural pigment, was used to determine its effect on carcass and skin pigmentation, immunity and growth performance of broiler chickens. Two hundred and forty 1-day-old Arbor Acres broiler chicks were randomly distributed into four treatment groups with six replicates in a randomized block design. Birds were fed basal diet for 42 d with or without supplementation of marigold flower extract at various concentrations, i.e., 0 (MG0, control), 100 (MG100), 150 (MG150) and 200 (MG200) mg/kg of feed, respectively. Feed intake and live body weight were weekly recorded. Carcass and shank color, and antibody titers against Newcastle and Influenza viruses were measured. Results showed that marigold flower extract significantly (p<0.05)... |

| ABSTRACT The present study was carried out to investigate the effect of dietary supplementation with vitamin E and stocking density on the mortality, body weight gain, feed conversion ratio, European production efficiency factor, heterophil/lymphocyte (H/L) ratio and liver glutathione (GSH) and malondialdehyde (MDA) levels of broilers. In total, 570 one-day-old Vencobb 400 broiler chickens were randomly assigned to three treatments, with six replicates each. G1 served as normal control and birds were provided a normal floor space (0.0465 m2/bird from day 1 to 21 and 0.0929 m2/bird from day 22 to 42) and basal diet containing vitamin E at 70 g/ton feed (n=150). G2 and G3 birds were subjected to high stocking density (0.0279 m2/bird from day 1 to 21 and... |

| The aim of this study was to compare performance and carcass characteristics of broilers fed diets with different Dietary Electrolyte balances (DEB) during the summer season. A total of 1,280 one-day-old Ross sexed chicks were distributed in 32 experimental units according to a randomized block design in a 4x2 factorial arrangement (4 levels and 2 sexes) and 4 replicates per treatment (40 birds per replicate). Feed program consisted of 3 phases (1-21, 22-42, 43-49 days of age). Experimental diets were formulated based on corn and soybean meal and adjusted to 210, 250, 290 and 330 mEq/kg of Na + K - Cl through the addition of sodium carbonate, potassium carbonate and ammonium chloride. Weekly measurements of body weight gain and feed intake were done, and... |

| ABSTRACT This study was conducted to examine the effects of garlic (G), black cumin (BC) and G+BC within the broiler rations, on performance, relative organ weights, intestinal morphology, serum biochemistry and plasma total oxidant/ antioxidant status. Two hundred broilers chicks (Ross 308) were used and they were divided into 4 groups consisting of 5 subgroups of 10 animals each. The trial was ended on the 35th day. No addition was made to the control group ration. 5g / kg garlic (G), 5g / kg black cumin (BC) and 5g / kg G + 5g / kg BC were added to the experimental group rations, respectively. There was no statistical difference among the trial groups in terms of BWG, FI, FCR and relative organ weights (p>0.05). Serum total protein (p<0.05) and... |

| ABSTRACT The objective of our study was to evaluate the effects of pineapple (Ananas comosus) leaf powder (PLP) on broiler performance. One hundred male broiler chicks (aged one day) were divided into five groups consisting of four pens as replicates, which were treated with basal diet (normal control); basal diet supplemented with 1, 2, and 3% PLP; or 50 mg/kg of zinc bacitracin (ZnB) as a positive control for 35 days. Body weights were significantly increased by 1.06, 5.67, 13.15, and 11.92%, respectively, and feed conversion ratios were decreased by 2.36, 8.49, 12.06, and 11.43%, respectively, in 1, 2, 3% PLP- and ZnB-supplemented groups, compared with the normal control group. Notably, the 2 and 3% PLP supplementations had beneficial effects on broiler... |
