Mevcut çalışma, Ross 308 etlik piliç ebeveynlerinde anaç yaşının kuluçka sonuçları ve civciv kalitesi üzerine etkilerinin belirlenmesi amacıyla planlanmıştır. Bu amaçla, çalışmada 30, 47 59 haftalık olmak üzere üç farklı yaş grubundaki damızlık anaçların yumurtaları kullanılmıştır. Her grubundan 150‘şer adet (50 × 3) toplam da 450 kuluçkalık yumurta tesadüfi olarak makinasına yerleştirilmiştir....
This study investigated the effectiveness of clove and cardamom alcoholic extracts as growth promoters on performance, carcass traits, some blood serum components, immunity parameters, intestinal microbial population morphology broiler chicks. To this purpose, a total 240 one-day-old chicks (Ross 308 strain) were distributed randomly into three groups in form completely randomized design. The e...
the objective of this study was to investigate the effects of dietary artichoke supplementation on performance, carcass traits and some blood parameters of broiler chickens. a total of 300, one day old broiler chicks (ross-308) were randomly allocated to 1 of 4 dietary treatments including: basal diet (control), basal diet supplemented with 1.5 or 3 percent of artichoke powder and also with 300...
High environmental temperatures have deleterious effects, reducing the feed intake, live weight gain and feed efficiency of poultry. A study utilizing Ross 308 was conducted to evaluate the effects of vitamin C (Ascorbic acid) and glucose on broilers production reared under heat stress (32 ± 2 °C). One day-old, five hundred twenty five broilers were randomly assigned to 7 treatment groups with ...
This experiment was conducted to determine the effects of dietary myrtle essential oil on small intestinal morphology and microbiology of broiler chickens. Two hundred day-old broiler chickens (Ross 308) were allocated to 5 treatments, 4 replications with a completely randomized design. The diets were supplemented with: no myrtle essential oil (control), each of myrtle essential oil at levels o...

Two hundred and sixteen day-old Ross-308 broiler chicks were allocated into 4 groups to study the impacts of different concentrations (0.0, 0.1, 0.15 and 0.2%) of β-hydroxy-methyl butyrate calcium (β-HMB-Ca), on values of tri-iodothyronin (T3) and tetra-iodothyronin (T4) hormones, liver enzymes [aspartate aminotransferase (AST) and alanine aminotransferase (ALT)], uric acid, peroxide, malondial...
The microbial profiles and activities of microbes in the digesta from chickens on diets containing Bogong or Canobolas with or without inclusion of microbial enzymes were investigated on the 384 day-old male Ross 308 broiler chickens. There was a reduction in population of C. perfringens (P < 0.01) of the ileum as a result of interaction between cultivar and xylanase. On the other hand, in the ...
Three experiments (Exp) were conducted to delineate a suitable model for inducing conditions mimicking physiological stress with minimal bird handling. For Exp 1, Ross x Ross 308 male chicks were fed a control diet or a diet containing 5 mg of corticosterone (CS)/kg from d 1 to 7. For Exp 2, Ross x Ross 508 broilers received 1 of 4 dietary treatments: control; control + 4 IU/kg of BW of adrenoc...
Infectious bronchitis is an acute viral disease with high contagious and mortality among chicks. Apparent symptoms of Infectious bronchitis in chicks are tracheal respiration and nasal discharges. The objective of this study was to assessment H120 vaccination efficacy on respiratory tract in Broiler Chickens.
