Broiler chickens reared under heat stress (HS) conditions have decreased growth performance and show metabolic immunologic alterations. This study aimed to evaluate the effect of supplementation with a standardized blend plant-derived isoquinoline alkaloids (IQ) on performance, protein catabolism, intestinal barrier function, inflammatory status HS-treated chickens. Three hundred sixty 0-day-ol...

This study was conducted to evaluate the effect of ractopamine, coenzyme Q and L-carnitine, 10 individually and in combination, on the hematological parameters of broiler chickens. A total of 512 one day-old male broiler chickens (Ross 308) were randomly divided to eight treatment groups. Each group had four replicates with 16 birds per each. Treatments were assigned as a 2 × 2 × 2 factorial ar...

The influence of in ovo administration of aromatase inhibitors, clomiphen citrate, tomoxifen, and garlic and tomato extracts on sex differentiation in broiler chickens were investigated in 2 experiments. Five hundred, and 1,000 fertile eggs from Ross 308 strain were used in experiments 1 and 2, respectively. In both experiments, eggs were divided into 5 groups: control group (DW, 0.1 mL/egg), t...

OBJECTIVE This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. METHODS Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each tr...

this study was conducted to investigate the effect of different levels of savory (satureja hortensis) powder and its essential oil on performance and antioxidant status of broiler chickens under heat stress (34±2 ˚c for 8 hours per day). a total of 336 one-day-old male broiler chicks (ross-308) were divided into 6 treatments and 4 replications (14 birds per replicate). experimental diets were a...

The aim of this study was to evaluate the ability of date pits (DP) to reduce the deleterious effects of aflatoxin B1 (AFB1) in broiler chicks. A total of 216 one-day-old male broiler chicks (Ross 308) were distributed randomly for nine treatments (with four replicates and six birds in each) for 35 days. The experiment included a 3×3 factorial arrangement of treatments involving three levels of...

The effect of dietary thyme-oil extract (TOE) supplementation on immune functions of broilers were assessed by feeding graded levels (50, 100, 200, or 400 ppm) of TOE to male broiler chicks during a 42-d feeding trial compared with negative- or positive-control diets. Dietary control treatments included a negative-control diet with no feed-additive supplementation and 2 positive-control groups ...

The effects of dietary vitamin E levels on mucosal maltase and alkaline phosphatase (ALP) enzyme activities and on the amount of mucosal malonyldialdehyde (MDA) in broiler chickens were studied in the present study. One hundred and eighty of male day old broiler chicks (Ross 308 strain) were randomly assigned into five groups, each with three replicates and 12 chicks in each replicate. Chickens...

This study examined the effects of nucleotide supplementation on broiler chick growth performance, immunological response, carcass traits, meat quality, serum biochemical parameters, total antioxidant capacity, intestinal morphology, mortality rate, and economic efficiency measures chicks. A 180 one-day-old chicks (Ross 308) were distributed into 6 groups, each which consisted 30 chicks, group ...
