| Experiment was conducted to study the effect of Metabolizable Energy (ME) and Balanced Protein (BP) on the performance of 1- to 35-day-old male and female Hubbard x Hubbard broilers. Set in a factorial arrangement, dietary treatments involved 3 levels of ME (2650, 2750, or 2850 kcal per kg diet) and 4 levels of Balanced Protein (expressed as 8.4, 9.0, 9.6, or 10.2 g Standardized Ileal Digestible lysine per kg). Each diet was fed to 5 replicate pens of 17 chicks. Dietary ME and BP did not interact for any of the parameters studied (p>0.05). The main effect of ME was significant (p<0.05) for feed intake, body weight, and feed conversion ratio at all ages. Highest ME (2850 kcal) resulted in 35 day feed intake and feed conversion ratio that was... |

| Ascites is a complex problem caused by many interacting factors such as genetics, environment and management. Many nutritional, medicinal and management strategies have been proposed to alleviate the problem. Higher levels of dietary vitamin C and E along with selenium yeast might be beneficial, presumably because of their role in improving cellular integrity. Oils rich in n-3 fatty acids have been shown to reduce pulmonary hypertension and, consequently, ascites incidence. The potential use of flax oil has already been demonstrated, whereas the effects of other oils rich in n-3 fatty acids (fish, linseed and canola oils) remain to be investigated. The assessment of the effects of dietary electrolyte balance on ascites incidence seems to be a promising... |

| ABSTRACT This study evaluated the potential of incremental doses of an enhanced Escherichia coli-derived phytase to support step-wise reduction of supplemental inorganic phosphate in an all-vegetable broiler diet. Corn-soybean meal-based diets containing 0.40/0.80%, 0.35/0.70%, and 0.30/0.60% avP and Ca, respectively from 0-10, 10-25, and 26-42 days posthatch served as experimental control (PC). Three test diets were formulated with 500, 1000, and 1500 FTU/kg of phytase assigned respectively an avP matrix of 0.15, 0.19, and 0.23% and a fixed Ca matrix of 0.15%. An additional diet (PC++) containing extra avP and Ca (+0.05% avP/+0.1% Ca) to that of PC was included to test if avP and Ca were not limiting in PC. Each diet was offered to 16 replicates of... |
