this experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. a completely randomized design with six treatments and six replicates was used.the six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...

background & aim: this experiment was conducted to examine the effect of different levels of echinacea purpurea (ep) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (aoa) in serum of broiler chicks. experimental: in this trial 240 one-day-old broiler chicks (ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 replicates with 1...

the effect of different levels of wood betony (wb), stachys lavandulifolia extract, as complement in feed, on the performance of common carp, cyprinus carpio was evaluated. the fish (44±0.62 g) was assigned to four treatments, three replicates each. the fish was fed on normal diet with no wb (control) vs. diet containing 2, 4 and 8% of wb extract. fish were successively fed on the diet, 2% live...

Background and Aims: Type and saturation of fatty acids can have an important impact on the level of triglyceride, cholesterol, very low and low-density lipoproteins in the blood and thus affect the development of atherosclerosis. Saturated fatty acids have an additive effect on blood cholesterol while for unsaturated fatty acids, a lowering effect has been reported. Fatty acids can have differ...

An experiment was carried out to compare the effects of laying hen’s diet supplemented with inorganic and different organic sources of selenium (Se) on quality and oxidative stability of eggs during storage. A total of 81, (35-week old) laying hens of Lohmann LSL-White were assigned to cages in a completely randomized design with 9 groups of treatment and 3 replicates of 3 birds. Hens in each g...

investigation on the food and feeding habits of silver carp in gobindsgar reservoir indicated that the diet of silver carp was dominated by cyclotella spp. (diatom) followed by chlorophyceae, cyanophyceae, crustacea, dianophyceae and rotifera. the size range of cyclotella spp. varied between 5-25 µm indicating that silver carp is capable to collect the food particles smaller than distance betwe...

This study was designed to investigate the effects of different levels of Tarragon powder on performance, carcass characteristics of broiler chickens. Two hundred Ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. At each replicate ten birds were used. Experimental diets were set on the basis of corn-soy-wheat and Ross 308 broiler chic...
