Enzymes are widely used in the food industry. Their use as a supplement to raw material for animal feed is current research topic. Although there several studies on application of enzyme additives industry, it necessary search new enzymes, well utilize bioinformatics tools design specific enzymes that work certain environmental conditions and substrates. This will allow improvement productive p...

an experiment was conducted to evaluate the effects of supplementing black cumin (nigella sativa) seeds (bcs) in diet on performance, liver weight and enzymes of broilers.the experiment was conducted as a randomized complete block design. two hundred forty day-old unsexed broiler chicks (cobb 500) were divided into four groups and assigned to four feeding treatments, with four replicates of 15 ...
