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 ...

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...

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...

BACKGROUND Heterogeneities of repolarization (R) across the myocardium have been invoked to explain most reentrant arrhythmias. The measurement of refractory periods (RPs) has been widely used to assess R, but conventional electrode and extrastimulus mapping techniques have not provided reliable maps of RPs. METHODS AND RESULTS Guinea pig hearts were stained with a voltage-sensitive dye to me...

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 ...

Introduction: The commonly used technique of radiation therapy for vulvar cancer consists of anteroposterior (AP) and posteroanterior (PA) fields. This is the first study that reports the dosimetric comparison between the AP-PA techniques and the new 3D advanced conformal technique (3D-ACT) based on the multiplicity of treatment fields in patients with squamous cell ca...

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...

AIM To investigate the effects of artemisinin (Art) on the action potentials (AP) recorded from identified C-type nodose neurons and study its anti-arrhythmic and anesthetic mechanisms. METHODS Neonatal and adult rats were selected for the preparation of isolated nodose ganglia neurons (NGN) and nodose ganglion-vagus slice preparation. Somatic AP were recorded from both isolated and slice NGN...
