Broiler performance as affected by dietary energy source and level
|
|
Abstract: Five different sources of oil/fat as energy sources (extruded full fat soy bean, dry fat, palm oil, poultry fat and soy oil) either using the practical and economical energy (Exp.1) or with different energy levels (Exp.2) in view of broilers performance, digestibility of nutrients, carcass characteristics, some blood constituents and economical efficiency.
The results obtained from the first experiment indicated that the best feed conversion was recorded for those fed the extruded full-fat soybean and the worst one was observed for those fed dry fat. While broiler chicks fed 3% soybean oil had the preferable weight gain.
The best edible parts as a proportional weight to live body weight was obtained for broiler chicks fed diets containing extruded full-fat soybean followed by those fed soybean oil. While, the worst one was recorded for chicks fed dry fat
During all of the experimental period, the lowest feed cost/kg gain (1.56 L.E) was observed for broiler chicks fed diets containing extruded full-fat soybean followed by those fed poultry fat (1.63 L.E).
Results of the second experiment showed that, increasing energy level during starter and finisher periods gave the best weight gain and feed conversion. Also, led to improve the digestible coefficient of nutrients. The high energy level gave the preferable values of edible parts. The preferable digestion coefficients were recorded for broiler chicks fed diets containing extruded full-fat soybean. Diets containing poultry fat had the best value for edible parts followed by those fed soybean oil. While the worst values were recorded for chicks fed dry fat.
The lowest values for blood cholesterol and Triglycerids were observed for broiler chicks fed diets containing soybean oil. The lowest feed cost/kg gain (1.61 L.E) was recorded for broiler chicks fed either extruded full-fat soybean or poultry fat, followed by those fed soybean oil (1.68 L.E) with the high energy level.
The practical and economical energy level as required for Arbor Acres broiler chicks was 3000 kcal ME/kg starter diet and 3100 kcal 8 ME/kg finisher diet. While, the preferable sources of oil/fat were extruded full-fat soybean, poultry fat or soybean oil. Whereas, the worst 8 one was dry fat.
