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 ...

The poultry market has changed due to a higher consumer interest on products with differentiated organoleptic characteristics, making of free-range broiler production a promising activity. This experiment was conducted to determine the digestible lysine requirements of Redbro Cou Nu male and female chickens during the starter phase (one to 21 days of age). Six hundred and thirty Redbro Cou Nu b...

this study was conducted to evaluate the effects of different levels of butyric acid triglyceride and prebiotics on performance, egg quality traits and blood lipids of laying hens.  a 2 × 4 factorial experiment with 4 levels of butyric acid triglyceride (0%, 0.15%, 0.30%, 0.45%) and 2 levels of prebiotic (0 and 0.15%) based a completely randomized design were conducted. one hundred and ninety-t...

320 one-day male broilers (ross 308) were divided in 4 treatments (with 4 replicate and 20 chicks for a replicate). all of broilers reared under a cold environmental temperature to induce ascites .experimental treatments were included 1: was fed a commercial corn-soybean meal- based diet meeting nrc (1994) including 1.2% arg and 40 iu of vitamin e/kg (control), 2: control with 400 iu of vitamin...

the present study was conducted to evaluate the effect of vinegar and phytase supplementation on performance, blood lipids, immune system and some carcass characteristics of broiler chickens. for this purpose 240 one-day old male broiler chicks was divided in a 2×2 factorial experiment based on completely randomized design with 4 treatments, 5 replicates and 12 chicks in each and reared through...

Commercial brown-egg layers have the genetic potential to produce 26.5 kg egg mass per hen housed (405 eggs with 65.5 g average weight) in a prolonged laying period of 16 months, with a feed conversion ratio of 2.1 kg feed per kg egg mass (Lohmann Tierzucht, 2011). Rapid growing broilers reach market weight of 2.1 kg live weight in 5 weeks, with a feed conversion of 1.6 kg feed per kg live weig...
