a total number of  5520 female and  480 male breeders (arbor acres plus) at 42wks of age  were used in a 10-week-trial to investigate the effect of an enzyme complex on  the quality  and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. there were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...

supplementary feed exogenous enzymes have improved the growth rates of various food animals. in thisresearch, the effect of endofeed w, a multienzyme feed supplement, was investigated on the growth of carp.accordingly, 134 fish (33.1 ± 0.8 g) were randomly allocated to 4 experimental groups. during the first stageof the experiment (10 days), groups 1-3 received 1, 2 and 3 g endofeed w per kg di...

Background & Aims: The prevalence, incidence, and complications of heart disease increase with age. Green tea is an antioxidant which can prevent cellular senescence and cardiovascular diseases. Telomerase enzyme decreases with aging. Acute exhaustive exercise results in disturbances in the oxidative system and production of active oxygen species in the heart tissue. Thus, the present study aim...

this experiment was conducted to evaluate the effect of the addition of a multi enzyme (natuzyme-p) to corn-soybean based diets and to determine the enzyme's nutrient equivalency on broiler chicks’ performance. ninety six day-old male broiler chicks were randomly assigned to a number of 24 battery cages in a completely randomized design. the chicks were grown up to 6 wk of age. six diets (...

The livers removed from thyroidectomized and L-T4 supplemented rats were rapidly frozen by Freon-12 chilled with liquid nitrogen, and concentrations of metabolites which affect glycogen synthetase and phosphorylase were determined. Serum and liver glycose levels were not changed in any thyroid functioning. But liver G6P and ATP were increased by thyroidectomy and decreased by L-T4 supplement, w...

the effect of phosphorus supplementation to ammoniated rice straw was studied. the in vitro experiment was carried out following the first stage of tilley and terry method. the treatments consisting of four diets were a= 50% ammoniated rice straw + 50% concentrate (control), b= a + 0.2% phosphorus (p) supplement, c= a + 0.4% phosphorus (p) supplement, and d= a + 0.6% phosphorus (p) supplement o...
