an experiment was conducted to evaluate the effects of 1α-oh-d3 either with or withoutcholecalciferol, microbial phytase as well as different levels of dietary calcium, and phosphorus onbroiler chickens, performance. a number of 576 male broiler chickens (ross 308) were made use of ina completely randomized design of a factorial arrangement (3×2×2×3), comprised of 36 treatments, 4replicates of ...

OBJECTIVE The objective of this experiment was to characterize the mRNA expression profile of type IIb sodium-inorganic phosphate cotransporter (NaPi-IIb) and the biochemical values of serum alkaline phosphatase (AKP), calcium, inorganic phosphorus, tibial ash and minerals of broiler chickens with aging. METHODS A total of 56 one-day-old Arbor Acres male broiler chickens were used. Broiler ch...

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...

Jurajdova J.: Levels of Minerals in Sera of Chickens Suffering from Marek's Disease. Acta vet. Brno, 47, 1978: 189-196. The concentrations were studied of sodium, potassium, calcium, magnesium and phosphorus as well as the correlations and coefficients of their level ratios in sera of RIR chickens 56 days after infection with Marek's disease virus, and they were compared with the controls. In t...

This study aimed to evaluate the effect of a heat stable phytase derived from Citrobacter braakii on true digestibility of P and on phytate dephosphorylation at the terminal ileum segment in broiler chickens. Four semi-synthetic diets, each containing either wheat, maize, soybean meal or rapeseed meal as the only source of phosphorus and calcium were supplemented with microbial phytase at 1000 ...

in order to evaluate the effect of feeding different levels of vermi-humus supplement (as a source of humic acid) on the performance of broiler chickens an experiment was conducted using 240 broiler chickens (ross 308) in a completely randomized design by four treatments (vermi-humus levels of 0, 0.5, 1 and 1.5 percent) and five replicates of 12 chickens per each for 42 day. the experimental tr...

Two experiments were conducted to study the effect of rapeseed cake and xylanase application on the digestibility and deposition of nutrients and energy in young broiler chickens. Experiment 1 was carried out on broiler chickens between the ages of 1 to 21 days, which were divided into three groups. The control diet contained soybean meal, whereas in the experimental diets a part of the soybean...

an experiment was conducted to evaluate the effect of replacing dietary limestone with mashhad power plant calcium-waste in combination with available phosphorus level on growth performance, tibial strength and blood alkaline phosphatase activity in broiler chickens. three hundred and eighty four male broiler chickens were used in a complete randomized design experiment with a 4×2 factorial arr...
