Effects of Enalapril on growth Performance, Ascites Mortality, Antioxidant Status and Blood Parameters in Broiler Chickens under Cold-Induced Ascites
Six hundred 1-d-old male broilers (Ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. From d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. Mortalities were inspected to determine the cause of death and diagnose of ...
متن کاملStrain and sex effects on ascites development in commercial broiler chickens
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...
متن کاملthe effects of polyunsaturated fatty acids on ascites incidence in broiler chickens
in order to evaluate the effect of polyunsaturated fatty acids on ascites incidence using this experiment was conducted 136 male one day (chicken ross 308) in a completely randomized design with 2 treatments and 4 replication and 17 chickens in each replicate. treatments includes: diet contain 4 % soybean oil (n3:n6:0.112) and diet include 5.5% poultry oil (n3:n6:0.201). birds were raised up to...
متن کاملComparative study on the beneficial effects of different dark-length schedules on the incidence of ascites and metabolic parameters in fast growing broiler chickens
BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...
متن کاملGraded atmospheric oxygen level effects on performance and ascites incidence in broilers.
The effects of graded atmospheric O2 concentration (12, 14, 16, 18, and 20.6%) on chick performance and propensity to develop ascites were investigated using commercial male broilers. Chicks were housed in calorimetry chambers for 2 wk with incoming air diluted with N to provide the desired O2 concentration at thermoneutral (TN) ambient temperature. Day 14 body weight, weight gain, feed consump...
