Two experiments were conducted to examine the influence of addition of microbial phytase to diets differing in native phytase content, on the performance of sows and digestibility of nutrients. Barley and wheat grains relatively poor in native phytase used in Experiment 1 mixtures were replaced by triticale and rye (rich in this enzyme) in Experiment 2 diets. There were 3 groups in each experim...

Male broilers (n = 416) were used to compare the efficacy of providing dietary phytase either as a commercial supplement or as a recombinant protein in transformed soybean. From 7 to 21 d of age, broilers were fed a basal diet containing 0.20% nonphytate P (nP) with additional supplementation by fungal phytase as Natuphos or as raw transformed soybeans expressing recombinant phytase at 400, 800...

The research is devoted to the feed value and amino acid composition of sprouted triticale grain. purpose study article presents results a 3 domestic varieties grains for use in industry. physicochemical parameters, as well mass fraction carbohydrates, content vitamins, mineral elements were studied. data obtained indicate that source easily digestible acids, fatty vitamins enzymes. According c...

This experiment was conducted to investigate the effects of supplemental phytase in a corn-wheatsoybean meal basal diet on phosphorus (P) digestibility and performance of broiler chicks. 378 one-day old broiler chicks (Ross 308) were allocated to 3×3 factorial arrangements with three levels of phytase enzyme (0, 500 and 1000 FTU/kg) and three levels of non-phytate P (100, 80 and 60% of NRC requ...

Effects of supplemental phytase and xylanase in a corn-soybean meal based diet containing 250 g/Kg wheat bran, were investigated. on broiler performance and phosphorus degradability and nitrogen digestibility. Phytase (500 and 1000 FTU) and xylanase (2700 and 5400 EXU) individually and in combination were added to the basal diet and given to 6 replicate groups (4 birds per replicate). At 21 day...

The paper presents the results of analysis usefulness mineral composition diets and effectiveness use vitamin supplements in feeding cows different technological groups. showed that amount calcium phosphorus was close to norm. Extremely high concentrations elements such as magnesium, potassium sodium were noted with an obvious lack chlorine sulfur. cation-anion balance positive: range indicator...

There is a distinct possibility that phytate negatively influences protein and energy utilisation in poultry and, as these influences would be ameliorated by phytase, there are substantial, practical implications. Despite several thousand scientific papers and a rapidly growing market the use of phytase and the importance of phytate in practical poultry nutrition remains an area of some confusi...

Phytase is traditionally supplemented into broiler diets between 300 and 600 phytase units (FTU)/kg. This supplementation releases phosphorus (P) from phytate in feed ingredients. The obvious benefit is the increase in available nutrients. Another benefit, when phytase is added to corn-soybean meal based diets, the production costs are reduced, leg abnormalities are minimized and bird growth ma...

Phosphorus in most diets for breeding sows is digested for 20 to 40%, thus leading to a relatively high amount of P in the manure. To enhance the P digestibility in diets for both lactating and gestating sows, two separate experiments were carried out to study the efficacy of Optiphos TM phytase derived from E. coli and produced by the yeast Pichia pastoris. Thirty crossbred gestating sows and ...

in order to investigate the role of bacillus cogulans on yield of two forage corn cultivars, an experiment carried out at agricultural research center of tehran province during 2009-2010. the experiment design consisted of three randomized complete blocks in a factorial arrangement. investigated treatments consisted of the kind of phosphorus and cultivar. the phosphorus factor included of the a...
