In order to investigate the effects of peppermint (Mentha piperita L.) alcoholic extract on liver injury caused by the oxidant carbon tetrachloride (CCl4), an experiment was performed as a completely randomized design in a factorial arrangement (2 × 2) with 4 replications of 10 broilers each. Factors included two levels of peppermint leaf alcoholic extract (0 and 2 mL/Kg body weight) and CCl4 (...

An experiment was conducted to study chlorpyrifos chronic toxicity in broilers and the protective effect of vitamin C. Oral administration of 0.8 mg/kg body weight (bw) (1/50 LD50) chlorpyrifos (Radar(®)), produced mild diarrhea and gross lesions comprised of paleness, flaccid consistency and slightly enlargement of liver. Histopathologically, chlorpyrifos produced degenerative changes in vario...

This study was conducted to evaluate the effects of dietary nettle (Urtica dioica) medicinal plant supplementation on growth performance, carcass traits, and blood biochemical and immunity parameters in female broiler chicks. A total of 300 (Ross-308) broilers were randomly allocated into one of the following dietary treatments: 1) control, " # " $ % # " $ % # " $ % # " $ % $ & ' $ chicks per p...

AIM Objective of this study was to investigate the effect of multicarbohydrases supplementation on performance of broilers fed low energy diet. MATERIALS AND METHODS A total of 75 days old chicks were selected and randomly divided into three treatments groups (T1, T2, and T3); each group contained 25 chicks distributed in five replicates of five chicks each. T1 group (positive control) was of...

Effect of photoperiod and food duration on body weight gain, energy intake, energy expenditure, and sexual development were investigated in two strains of Japanese quail ( Coturnix c. japonica ), bred for meat (broilers) or egg production (layers), from 7 to 71 days of age. In a first experiment chicks were subjected to 18L:6D, 15L:9D, 12L:12D, 9L:15D, or 6L:18D, with ad lib food during the lig...

This study was performed with broiler chickens to evaluate the effects of adding beta-glucanase on bird performances and digestive organs weights. A total of 1600 1-day-old broilers (Arbor Acres) were divided into 2 groups and fed either a control diet (group C) based on corn, wheat and barley or a control diet supplemented with beta-glucanase preparation (Safizym GP 40, Lesaffre Feed Additives...

The benefits of feeding avilamycin (Surmax/Maxus, Elanco Animal Health) to broiler chickens were demonstrated in a floor pen study (two trials) in which avilamycin was fed at 10 ppm in a 45-day growout. Final live weight of broilers fed avilamycin was significantly (P < or = .01) heavier (90 g) than that of control broilers fed for an equal number of days. Feed conversion was numerically but no...

Effect of photoperiod and food duration on body weight gain, energy intake, energy expenditure, and sexual development were investigated in two strains of Japanese quail (Coturnix c. japonica), bred for meat (broilers) or egg production (layers), from 7 to 71 days of age. In a first experiment chicks were subjected to 18L:6D, 15L:9D, 12L:12D, 9L:15D, or 6L:18D, with ad lib food during the light...
