Sunflower Meal and Enzyme Supplementation in Diets of Broilers from 21 to 42 Days of Age
The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...

This experiment was conducted to study the effect of type of feed processing and type of phytase enzyme on growth performance, calcium, phosphorus tibia and toe ash ,fecal and ileal digestibility of phosphorus in broiler chickens. A total of 420 broiler chicks (Ross 308) were used in a completely random design in the a 2×3 factorial arrangement using two processing methods (pellet and mash) an...
متن کاملPower of two methods for the estimation of bone ash of broilers.
An experiment was conducted to compare two common methods of estimating bone ash from growing broiler chicks (A = autoclaving; B = boiling/extracting). Ross x Ross 1-d-old broiler chicks were fed a corn-soy, phosphorus-deficient diet (22.7% CP, 1% calcium, 0.22% non-phytate phosphorus), with 0, 750, 1,500, 3,000, or 6,000 units of phytase (FTU) to produce bones with a range of ash. The methods ...
متن کاملEffect of Phytase Superdoses and Citric Acid on Growth Performance, Plasma Phosphorus and Tibia Ash in Broilers Fed Canola Meal-Based Diets Severely Limited in Available Phosphorus
This experiment was conducted to investigate the effect of phytase superdoses alone or in combination with citric acid (CA) in canola meal-based diets severely limited in available phosphorus (Pa) on growth performance, plasma phosphorus (P), and tibia ash (TA) in broilers from 22 to 42 d of age. Two hundreds and eighty 21-d-old male broilers were used in 28 pens of 10 birds per each. The exper...
