The objective of this study was to assess the importance of strain and sex and their interaction effect on broiler chickens’ performance and susceptibility to ascites. Chicks from three strains (Ross 308, Cobb 500 and Arian, labeled as A, B and C respectively) were obtained from the same age breeder and sexed when one-day-old. Each crosses’ sex was assigned to four pens of 60 broilers each. Bod...

This study was conducted to investigate the effects of garlic powder (GP) black seed (BS) and plant premix (GP and BS) in the diet on broiler growth performance and intestinal morphology. included 480 Hubbard broiler chicks(day-old). There were 4 treatment groups each consisting of 3 replicates. The four dietary treatments consisted of a control (basal diet), basal diet +0.5% GP, basal diet +0....

effect of adding melissa officinalis aqueous extract was studied on immune response and performance in 200 ross 308 broiler chicks in a completely randomized design with five treatments and four replicates and 10 observations per replicate. the amounts of 0 (control), 0.5, 1, 1.5 and 2 ml/l lemon balm extract were added in drinking water for 42 days. humoral immunity was evaluated by injection ...

This study was conducted to investigate the effects of artichoke powder on performance and immune function of Japanese quails poisoned with carbon tetrachloride (CCl4). One hundred meat type (1-d-old) quails were assigned randomly to 4 treatment groups (n=25). Treatment groups included with the study were: 1) control group (without artichoke supplementation or CCl4 administration, 2) group with...

effect of intermittent mash-pellet feeding programs on broilers performance, ascites susceptibility and economic yield was studied using 480 broilers in six treatments and five replicates of 16 chicks per pen were used in a completely randomized design. treatments including: 1. mash feed, 2. heated-mash feed, 3. mash feed in starter and grower and pellet feed in finisher, 4. mash feed in starte...

the aim of this study was to investigate the effects seaweeds gracilariopsis persica in diets on performance and tsh, t3 and t4 hormones in serum of laying quail. a total of 112 laying quails were randomly allocated into four dietary treatments (diets containing 0, 1, 3 and 5% seaweed) with 4 replicates of 7 birds each. the birds were fed on experimental diets for 12 weeks. eggs were collected ...

A total of 240 Ross 308 day-old male broiler chicks within a completely randomized design were used in this experiment to evaluate the effects of dietary inclusion of turmeric powder and cinnamon powder on performance and some immune responses of broiler chickens. Dietary treatments were as follow: a corn-soybean meal basal diet (control); basal diet + 10 ppm avilamycin; basal diet + 2.5 g/Kg t...

this experiment was conducted to compare the effects of quantitative feed restriction and meal feeding on the performance, carcass compositions and ascites syndrome in male broiler chickens (ross 308). in this study, 5 schedule feed restrictions include: 1) ad libitum food intake (al group), 2) feeding maintenance energy requirement from 7 to 14 d of age 3) feeding to support 50% of the normal ...
