Significance of stocking density in broiler production i.e. production performance, vitality and health condition of chickens, was established at the beginning of development of industrial poultry production. However, considering intensive development of selection work and creation of more productive genotypes which, at the same time, were more demanding in regard to rearing conditions, the cur...

the effects of selko-ph (s; 1 ml/l drinking water); termin-8 (t; 2 kg/ton feed) and neogermicin (n; 2 l/ton feed) on gastrointestinal tract (git) ph, microbial population, ileal digestibility and broiler performance were investigated. the lowest feed intake (fi) was attained by chickens fed diets supplemented with s group in all periods (p

objective: a research was carried out to investigate the effects of nettle (urtica dioica) powder (np) and essential oil (ne) on performance, blood metabolites, carcass characteristics and antioxidant stability in broiler chicks. methods: the treatments were t1: control diet, t2: control diet + 5g/kg np, t3: control diet + 10 g/kg np, t4: control diet + 5g/kg ne and t5: control diet + 10 g/kg n...

a total of 150 day old female chickens (ross 308) were randomly allocated to 2 groups with 5 replicate and 15 chicks in each replicate to determine the effects of cold induced ascites on performance, antioxidant status, blood enzyme activities and bone metabolism. the two experimental treatments were: 1) chicks that reared under normal temperature (nt) and 2) chicks that reared under cold tempe...

this study was conducted to evaluate the effects of feeding mash versus pellet with different thermal process on blood metabolites, carcass characteristics and broiler performance. 192 (one-day) cobb broiler chicks were used in a completely randomized design with 4 experimental groups (diets) and 4 replicates of ten chicks each (totally 16 pens). the experimental treatment groups consisted of m...

this experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (pbpm) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. three samples of pbpm produced in ardabil province located in northwest of iran, were provided during one month sampling peri...

an investigation was carried out to evaluate the growth performance of six commercial broiler hybridsavailable in iran (arbor acres, arian, cobb 500, hubbard, lohmann and ross 508). two hundred and fiftyfertile eggs of each hybrid were taken from different breeder farms, all over the country. the similarity offlocks ages and their health conditions were considered. after hatching, the sexed chi...

this study was conducted using one hundred and eighty (180) day-old broiler chicks, of anak strain to assess the levels of inclusion of indomie waste meal as a substitute for maize at 0, 25, 50, 75 and 100%. the birds were randomly assigned to dietary treatments using completely randomized design (crd). each treatment contained 3 replicates and each replicate had 6 birds. the study lasted for e...

this experiment was conducted to investigate the effects of different levels of canola oil and diet mixing time length on performance, carcass traits and blood lipids in broilers. in this experiment 288 ross-308 broilers were used from 11 up to 42 days as factorial arrangement (3×2) included three levels of canola oil (0, 3 and 6%) and two mixing time length (10 and 15 minute) in 6 treatments, ...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal sciences university poultry farm to find out the effects of different oils on productive performance of broilers. the chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. each treatment had 150 birds, with...
