Effects of Levels of Inclusion of Locally Processed Fish Waste Meal in the Diets of White Leghorn Layers on Performance Parameters, Hatchability, Economics, Egg Production and Egg Quality
The study was conducted at Haramaya university poultry farm to evaluate the effects of locally processed fish waste meal (FWM) in the diet of white leghorn layers on the performance and hatchability, egg quality, sensory flavor and profitability of the rations. One hundred eighty chickens at five months of age were randomly distributed (15 layers per each 12 pens). The pens were randomly assign...

متن کاملEffects of Reducing Dietary Crude Protein with Amino Acids Supplementation on Performance of Commercial White Leghorn Layers during Late Production Period
Several strategies are being developed to minimize nitrogen (N) pollution from poultry waste in areas with high concentrations of commercial poultry operations. This study focus on the effect of feeding reduced protein (CP) diets on laying hens housed under commercial conditions. The experiment was carried out using 144 Hy-Line W-36 hens which were randomly assigned to one of four dietary treat...
متن کاملEffects of Reducing Dietary Crude Protein with Amino Acids Supplementation on Performance of Commercial White Leghorn Layers during the Second Production Period
Use of low protein diets could have potential benefits on nitrogen emissions reduction as well as potential cost savings by reducing the utilization of high cost protein sources. An experiment was conducted with 160 Hy-Line W-36 hens which were randomly assigned to one of four dietary treatment groups. Corn-soy based diets varying in dietary crude protein (CP) supplemented with commercially ami...
