in order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. treatments were the diets as follow: 1) diet for...

objective(s): silver nanoparticles (ag-nps) are one of the most widely used nanomaterials recently. despite the wide application of nanomaterials, there is limited information concerning their impact on human health and the environment. this study aimed to find the effects of ag-nps (40 nm) on blood serum, liver and kidney tissues of homing pigeons (columbia livia).materials and methods: columb...

in the present study, changes of values of serum 17ß-estradiol (e2), asparate amino teransferase (ast), alanine amino transferase (alt) and lactate dehydrogenase (ldh) following intraperitoneal (i.p) injection with the aromatase inhibitor (ai) letrozole were investigated in rainbow trout (oncorhynchus mykiss). forty- eight apparently healthy rainbow trout (mean weight of 845 g) divided in four ...

a study was conducted to evaluate efficacyof wheat based vs. corn based diets on growth performance, carcass traits,blood parameters, jejunum morphological development, immunity, cecal microflora and excreta moisture in broiler chicks fed according to digestible essential amino acid profile. one hundred forty day old ross 308 male broiler chicks randomly distributed into ten separated floor pen...

arginine (arg) requirements of male broilers (ross 308) reared at high altitude (2100 mabove sea level) during the 1-to 3-week period was estimated in a graded supplementationmethod, in which six diets (230 g kg-1 cp and 3200 kcal me kg-1) with arg increments of1.25 g kg-1 were applied to four pens of fifteen birds each. dietary arg content of theexperimental groups ranged from 10 g kg-1 (80% o...

brachystegia eurycoma is predominantly grown in the eastern region of nigeria. its seed is used in food majorly as a soup condiment, flavouring agent and soup thickener. the proximate, mineral and amino acid compositions were determined on raw and processed seeds (boiled, fermented and roasted) using standard analytical techniques. the processing methods showed deviations in nutrients from the ...

in recent years considerable interest has been focused on the plasma amino acid patterns as a possible index of protein malnutrition, in children. thus a change in the ratio of non-essential to essential amino acids is considered to be significant in the development of protein malnutrition. the present paper reports a simplified and rapid chromatographic procedure for the determination of this ...
