Effect of Microbial Phytase in Soybean Meal Based Broiler Diets Containing Low Phosphorous
A six wk feeding experiment was conducted with d-old four hundred broiler chicks (Ven Cobb) to determine the effects of microbial phytase (Allzyme) supplementation in soybean meal based broiler diet containing low phosphorous. These birds were randomly divided into four dietary treatment groups of 100 broilers each. Each treatment group was further sub-divided into five replicates of 25 broiler...
متن کاملEffect of thymol and carvacrol on nutrient digestibility in rams fed high or low concentrate diets
Published data on the effects of essential oils (EO) on in vivo nutrient digestibility in sheep are contradictory. In 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete Latin Square designs. The essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...
متن کاملGrowth Performance of Growing Pigs Fed Crude Protein-Adequate or Deficient, Low Phosphorus Diets with Graded Levels Of Phytase
Nitrogen and phosphorus are the nutrients that are potential environmental pollutants when excessive quantities are applied to soils (Jongbloed and Lenis, 1998). These nutrients are excreted as a consequence of normal metabolic processes, but dietary excesses lead to increased manure excretion. Exogenous phytase (PT) as a dietary additive is widely accepted as an effective strategy for reducing...
متن کاملEffects of supplemental phytase on nutrient digestibility and performance of sows fed diets with high or low native phytase activity
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...
متن کاملUdk = 636.085.1 Impact of Phytase Supplementation on the Calcium and Phosphorous Retention in High Producing Layers
The calcium and phosphorous retention of layers was evaluated at different production levels (45 75 95 % of final production peak) with Hy-Line Brown hybrid layers during the first twelve weeks of the laying cycle. 32 layers evenly distributed over 4 treatments (Trts). The Ca content of the diets was identical across all Trts (32,5 g/kg), while P contents and phytase activities differed. In the...
