in this experiment, randomized complete block design with four replications was used for evaluating of the effect of three feeding methods including: without feed restriction (control group), 6 hours feed restriction from 7 to 21 days and 4 hours from 22 to 28 days, 6 hours feed restriction from 7 to 14 days and 4 hours from 15 to 21 days on performance and ascites prevention of arian male broi...

The current study evaluated the effect of a commercial wheat-maizesoybean meal based diet supplemented with an organic acid product containing a specific combination of formic and propionic acids (pHorce) on performance parameters in broiler chickens. One day-old broiler chickens (Ross 308) were randomly allotted to 2 treatments with 10 replicate cages/treatment and 2 birds/cage from d 1 to 21....

The experimental materials comprised 800 Cobb 500 broiler chickens. One-day-old chickens of both sexes were randomly allocated to two feeding groups, each with four replicates of 100 birds. The chickens were reared for six weeks on deep litter and were fed standard pelleted diets in a three-stage system (starter, grower and finisher). Control group (I) birds received basal diets and experimenta...

a 42-d trial with 400 unsexed broiler chicks (cobb 500) was conducted to study the effects of licorice (glycyrrhizaglabra) extract and an antibiotic-lincomycin- on performance abdominal fat and weights of selected internal organs, blood metabolites immunity system response. the feeding program consisted of a starter diet (1-21) d of age and a grower diet (22-42) d of age. chicks were randomly a...

the objective of this study was to compare growth performance and feed conversion ratios of rainbow trout (oncorhynchus mykiss) and brook trout (salvelinus fontinalis) juveniles in monoculture and duo-culture in freshwater and seawater under aquarium conditions. the fish were about 2-months old hatchery-reared brook and rainbow trout with initial weights of 0.934±0.033 (n=360) and 1.014±0.019 (...

the acehnese mahseer, locally known as keureling, tor tambra is one of the highest economically valued freshwater fishes found in aceh waters. the culture of t. tambra was initiated in aceh province, indonesia more than five years ago. however, the growth rate in captivity has been low, probably due to feeding problems. hence, the objective of the present study was to evaluate the optimum level...

background: comparison between infectious bursal disease vaccines. objectives: comparison between foreign and iranian intermediate uncloned gumboro vaccines on feed conversion ratio. methods: three hundred and thirty day-old chicks were purchased and for determination of vaccination time by deventer formula, thirty chicks were randomly bled and the remaining chicks divided into 3 equal groups, ...

an experiment with 300 one-day old ross male broiler chicks was conducted to determine the effects of glauconite and zeolite on the broiler's performance, tibia bone and blood characteristics. five experimental treatments [control, glauconite (2 & 4 percent), and zeolite (2 & 4 percent)] were used in a completely randomized design with 4 replicates. during the experiment weight gain, feed ...

to study the possible use of phytase and yeast (saccharomyces cervisiae) in corn-soy bean meal base diet with different levels of available phosphorous in arbor acers broiler chicks, an experiment was conducted with 264 day old chicks of an average weight of 44.6 grams each. a completely randomized design of 6 treatments and 4 replications (11 chicks per replicate) for periods of starter, growe...

The growth of 64 pigs was monitored over grower and finisher periods of 26-58 and 58-96 kg respectively, to see if the optimum dietary ratio of threonine to lysine (T/L) under ad Zibitum feeding was higher than the generally accepted ratio of 0.6. Five basal (Bl-B5) diets were used to establish the pig’s response to lysine (in the range 6.0 to 11.24 and 5.59 to 10.5 g kg-1 for grower and finish...
