This experiment was conducted to determine the requirements of vitamin supplement and available phosphorus in broiler chickens from 42 to 56 days of age. In a completely randomized design, with a 3×3×3 factorial arrangement, 270 one-day-old commercial broiler chicks were divided into 27 groups (replicates) with 9 treatments, 3 replicates and 10 chicks in each group. Each of the nine diets was g...
The present experiment was conducted to assess the efficacy of liquid methionine hydroxy analogue-free acid (MHAFA) in comparison to DL-methionine (DL-Met) in broilers. 567 day-old Avian chicks were divided into 7 treatments with 5 replicates of 16 birds each. During the 35d (7-42 d) experimental periods chicks were given two basal diets. From 7 to 21d of age, a starting basal diet containing 1...
The milk/solid feed intake pattern and digestive capacity were compared in two groups of young rabbits reared between 16 and 32 days in litters of four (L4 group, n = 18 litters) or ten pups (L10, n = 20) in order to modulate milk availability. Compared to the L4 group, rabbits in the L10 group presented a lower milk intake (22.3 versus 28.8 g x day(-1)) and a higher solid feed intake (12.9 ver...

a study was conducted to evaluate the effects of blood pressure medications on index of liver damage in ascites incidence in broilers. a completely randomized experimental design with a 2×3 factorial arrangement (sex and feed additive), with 3 replicates of 12 birds, with 216 (108 male and 108 female) one-day-old (ross 308) was applied. feed additive includes control (without feed additive) lev...
OBJECTIVE "Reference ranges" are developed when it is impossible or inappropriate to establish "normal ranges" by drawing blood on healthy normal volunteers. Reference ranges for the hematocrit and the blood hemoglobin concentration of newborn infants have previously been reported from relatively small sample sizes by using measurement methods that now are considered outmoded. METHODS We soug...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
The serum proteinograms of 10 female Holstein calves fed milk either through conventional (COV) or step-down (STP) milk feeding methods at different ages were evaluated. Calves fed using the COV method were fed colostrum during the first 24 hours that they stayed with their respective mothers and received transition milk for another 2 days and later, and then milk at four liters/day for 59 days...
A study was conducted to evaluate the effects of an artichoke extract on broiler production performance traits by comparing the results of two inclusion rates in broiler diets from 0 to 21 days of age. A total of 2880 day-old male broiler chicks was randomly assigned to 36 floor-pens and raised from 1 to 42 days of age. The CONTROL group received a comsoya meal basal diet. In the treatment diet...
