BACKGROUND: Phosphorous is one of the expensive nutrients in poultry feed. Therefore, improving the bioavailability of this nutrient in feed ingredients could be effective for lowering the cost of feed. OBJECTIVE: This study was performed to evaluate the effect of pre-treatment of feed ingredients by commercial enzymes and different levels of pH on releasing of phosphorus from phytate under in ...

Herein, we investigated the effect of Chlorella vulgaris as ingredient (10% incorporation) in broiler diets, supplemented or not with 2 formulations Carbohydrate-Active enZymes (CAZymes; Rovabio Excel AP and a mixture recombinant CAZymes, composed by an exo-?-glucosaminidase, alginate lyase, peptidoglycan N-acetylmuramic acid deacetylase lysozyme), on growth performance, meat quality, fatty com...

The study was conducted to investigate the effects of a multi-enzyme complex (Rovabio Excel) containing carbohydrolase activities on the performance of broiler chickens. Test diets were formulated to include 12% corn distillers dried grain with solubles (DDGS). In total, 1200 Cobb 500 broiler males were randomly assigned to 8 replicate pens of 50 birds per treatment and grown to 45 d of age usi...

1. Cellulases and xylanases display a modular architecture that comprises a catalytic module linked to one or more non-catalytic carbohydrate-binding modules (CBMs). CBMs have been classified into 52 different families, based on primary structure similarity. These non-catalytic modules mediate a prolonged and intimate contact of the enzyme with the target substrate eliciting efficient hydrolysi...

1. Exogenous microbial beta-1,3-1,4-glucanases and hemicellulases contribute to improving the nutritive value of cereals rich in soluble non-starch polysaccharides for poultry. 2. In general, plant cell wall hydrolases display a modular structure comprising a catalytic module linked to one or more non-catalytic carbohydrate-binding modules (CBMs). Based on primary structure similarity, CBMs hav...

The DE values and digestible nutrients content of 6 diets were measured in 60-kg male growing pigs fed restricted amount of feed. Diets were prepared from 5 ingredients [wheat (Triticum aestivum), corn (Zea mays), barley (Hordeum vulgare), wheat bran, and soybean (Glycine max) meal; inclusion levels of ingredients were not correlated] with or without carbohydrose enzyme (Rovabio Excel AP; 3300 ...

Here I present an Excel based program for the analysis of intracellular Ca transients recorded using fluorescent indicators. The program can perform all the necessary steps which convert recorded raw voltage changes into meaningful physiological information. The program performs two fundamental processes. (1) It can prepare the raw signal by several methods. (2) It can then be used to analyze t...

This study was conducted to investigate the effects of dietary supplementation with multiple enzymes composed of phytase plus carbohydrolases (ROVABIO Max, RM) on growth performance, nutritional availability and intestinal viscosity in broiler chicks. A total of one thousand, one-day-old male broiler chicks were randomly allotted into treatment groups that received one of five experimental diet...
