this experiment was conducted to evaluate the effects of different levels of artemisia sieberi oil (zero, 100, 200 and 300 mg/kg) and antibiotic on performance and blood parameters in broiler chicken. 200 day-old broiler chickens (ross 308) were allocated to five treatments, four replications with a completely randomized design. in total period, broilers were fed dietary artemisia sieberi oil a...

background: with the removal of antibiotic as growth promoters from poultry diets, it is of interest to investigate potential alternatives to maintain good growth performance and good intestinal microbial populations in these birds. numerous additives such as probiotics, prebiotics, organic acids, enzymes and herbal extracts used extensively in poultry feed. objective: the study was conducted t...

The present study aimed at evaluating the effect of the probiotic thepax and yogurt (as probiotic) on the growth response and intestinal microflora results of broiler chickens. Two hundred forty day-old Ross 308 broilers were equally distributed into 12 floor pens and reared for 42 day. The treatments consisted of yogurt (10, 5 and 2.5% during starter, grower and finisher periods in the drinkin...

The present study investigated the dietary impact of dried olive pulp (OP) on growth performance, gut health and some welfare behavior characteristics broilers. It was conducted in a commercial poultry farm using 108 13 day-old Ross male Chickens were equally randomly assigned to 3 treatments, CON, OP3 OP6, based incorporation rate OP ration (0%, 3%, 6%, respectively). A beneficial foot pad der...

This experiment was carried out to investigate the effects of different levels chromium picolinate (CrPic) and chromium nanoparticles (nano-Cr) on the performance and immune function of broilers under heat stress condition. A total of 320 Ross 308 broiler chicks (from 21 to 42 days) were assigned randomly into eight treatment groups (four replicates per treatment, and 10 chicks per replicate) a...

AIM In this study, a planned research work was conducted to investigate the nutrigenomic aspects of supplementation of Allium sativum (garlic) and Ocimum sanctum (holy basil) leaf powder on the growth performance and immune characteristics of broilers. MATERIALS AND METHODS A 6 weeks feeding trial was conducted with 280-day-old Ven Cobb broilers, distributed randomly into seven experimental g...

This study was carried out to investigate the effects of tributyrin (TB) on the growth performance, pro-inflammatory cytokines, intestinal morphology, energy status, disaccharidase activity, and antioxidative capacity of broilers challenged with lipopolysaccharide (LPS). A total of 160 one-day-old Cobb broilers were allocated to 1 of 4 treatments, with 4 replicated pens per treatment and 10 bir...

A study was conducted to compare the growth performance as well as blood and carcass variables of two broiler strains reared in a conventional broiler house and a modified greenhouse equipped with cooling pads and tunnel ventilation system. Eight hundred day-old chickens of two commercial strains (Ross  308 and Lohmann) were selected and placed in  8 floor pens (4 pens of  50 broilers for each ...

This study evaluates the effects of different levels of guanidinoacetic acid (GAA) supplement on growth performance and gut morphology in broilers (Ross 308 strain) raised at high altitude (2100 m). A total of 300 one-day-old male broiler chicks (Ross 308 strain) were used in a completely randomized design with five treatments and four replicate pens of 15 birds in each. Five dietary treatments...
