background & aim: a feeding trial was conducted to investigate the effect of periodically use of garlic on growth ‎performance, and antibody titer to newcastle and infectious bursal diseases in broiler ‎chickens. experimental: ross broiler chicks randomly allocated into the 10 dietary treatments ‎for 6 weeks. a 3 × 4 factorial experiment was used as three periods of feeding (starter, grower...

the mucus layer plays an important role as an intermediate for the protection of the gut against acidic chyme, digestive enzymes, and pathogens; in addition, it acts as a lubricant and facilitator of nutrient transportation. phytogenic compounds seem to promote intestinal mucus production. objectives: the current study was conducted to investigate the effects of low and high levels of energy an...

changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...

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...

this experiment was conducted to determine the effects of myrtle essential oil (meo) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. a total of 200 ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...

Emerging evidence suggests a potential role of stearoyl-CoA desaturase (SCD)-1 in the control of body weight and energy homeostasis. The present study was conducted to investigate the effects of several energy balance-related factors (leptin, cerulenin, food deprivation, genotype, and gender) on SCD gene expression in chickens. In experiment 1, 6-week-old female and male broiler chickens were u...

The direction of production for indigenous chicken breeds is currently unknown and this knowledge, combined with the development of chicken genome-wide association studies, led us to investigate differences in specific loci between broiler and layer chicken using bioinformatic methods. In addition, we analyzed the distribution of these seven identified loci in four Chinese indigenous chicken br...

A diet for broiler chickens that provides the nutrients essential for maintenance and growth of the flock as a whole may also have chemical and physical properties which are detrimental to the processes of ingestion, digestion, absorption, transport and utilization of nutrients. The digestive capacity of the chicken can be modelled according to interactions between feed– related and bird–relate...

The aim of the present study was to evaluate the effect of feeding four levels of tuna oil on performance and fatty acid (FA) profiles of broiler chicken meat. 240 Ross broiler chickens were randomly assigned to 20 pens and divided into four treatments: 0%, 0.75%, 1%, and 1.25% of tuna oil. At 49 days, breast and legs-thighs muscles were processed for FA analysis. Concentrations of FA in legs a...

Salmonella enterica ssp. enterica is a leading cause of bacterial food-borne disease outbreaks worldwide and is also an economic burden particularly in Reunion Island because its population consumes large amounts of chicken and cooks 100% chicken sausages (35 kg per capita per year). The aim of this study was to investigate the epidemiology of Salmonella Typhimurium and Salmonella 1,4,[5],12:i:...
