This study was carried out to measure the prececal protein and ether extract digestibility of shrimp and fish meal using the regression approach. A total of 280 Cobb 500 day-old broilers (mixed sexes) were randomly allotted to 7 treatment groups (4 replicates of 10 broilers each) in a completely randomized design. Feed intake was higher in the birds that received protease-supplemented shrimp me...

the effect of ethanolic extract of iranian green propolis, rosemary and earthworm meal to determine on performance, immune system and blood metabolites of japanese quail, using 160 mixed-sex quail chicks in a completely randomized design by four treatments (including ethanolic extract of propolis 0.1 percent, rosemary leaves meal 0.5 percent, earthworm meal 0.5 percent and control) and four rep...

in this experiment 240 hy-line (w-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. the amounts of watermelon skin meal (wsm) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. the results showed that using wsm up to 2% significantly improved the performance and...

effect of levels of zinc supplementation on footpad lesions, reproductive and blood parameters of broiler breeders with 300 hens and 40 roosters of ross 308 strain with four treatments, five replicates and 15 hens and two roosters in each for 12 weeks was evaluated in a completely randomized design. dietary treatments were 80, 110, 140 and 170 mg zinc/kg diet. increasing supplemental zinc level...

in order to investigate the effect of adding fennel powder (foeniculum vulgare) in starter diet on performance, immunity system and biometric parameters of holstein calves, 30 holstein calves (15 males and 15 females) with birth weight of 40±0.5 kg were used in a completely randomized design. experimental diets were: 1. starter without fennel powder (control), 2. starter containing 0.4% fennel ...

a methodology to regenerate whole plants of fig tree (ficus carica cv. jaami-e-kan) from apical meristem of greenhouse plantlets was developed. two meristematic explants size (0.2-0.4 and 0.5-0.7 mm), two kinds of culture media and three concentrations of 6-benzyladenine (0.5, 1 and 1.5 mgrl-1) were tested as a completely randomize design (crd) with a simple factorial arrangement for establishm...

although water deficiency has been seriously taken up as a subject in reducing crop production in arid and semi–arid areas, nevertheless little information has been published regarding its effects on seed quality. to evaluate the effects of irrigation regimes (full irrigation (control), irrigation until flowering stage, irrigation until doughing stage and irrigation until eight-leaf stage) on g...

the objective of this study was to evaluate whether the adverse effects of high dietary rice bran (rb) inclusion levels on the feed intake, performance, bone status and nitrogen (n) retention of broilers could be mitigated by wet feeding. giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

this experiment was conducted to evaluate the effects of different levels of artemisia sieberi oil (zero, 100, 200 and 300 mg/kg) and antibiotic on performance and blood parameters in broiler chicken. 200 day-old broiler chickens (ross 308) were allocated to five treatments, four replications with a completely randomized design. in total period, broilers were fed dietary artemisia sieberi oil a...
