an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...
This experiment was conducted to study the effect of type of feed processing and type of phytase enzyme on growth performance, calcium, phosphorus tibia and toe ash ,fecal and ileal digestibility of phosphorus in broiler chickens. A total of 420 broiler chicks (Ross 308) were used in a completely random design in the a 2×3 factorial arrangement using two processing methods (pellet and mash) an...
بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
An experiment was carried out to determine the effect of age and caponization on the development blood and bone characteristics development in male country chickens in Taiwan. A total of two hundred 8-wk-old LRI native chicken cockerels, Taishi meat No.13 from LRI-COA, were used as experimental animals. Cockerels were surgically caponized at 8 wks of age. Twelve birds in each group were bled an...
This experiment was conducted to determine the phosphorus relative bioavailability of eight samples of dicalcium phosphate. Bioavailability of Samples of dicalcium phosphate was evaluated and their effects on performance of laying hens were investigated. Commercial samples of Dicalcium Phosphate were provided from the following manufacturers: Iran Phosphate, Partove Bashash, Godaze, Poya Khojas...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...
Ash, minerals and biochemical contents were determined in various parts of root, stem and leaf of Cissus quadrangularis. The maximum ash content was observed in the root. The maximum concentration of carbohydrate and protein in the root and phosphorus, iron, calcium and lipids in the stem were observed.
An experiment was carried out on 384 7d old commercial broiler chicks (Lohman) to study the effect of changes in source and level of dietary calcium and limestone particle size on the performance and tibial growth and calcification of broiler chicks. From day 1 to day 7, the chicks were fed with the commercial basal diet. On day 7, the chicks were weighted and randomly assigned to 64 groups, si...
