Dietary Energy In Broiler
Hill et al 1956.
Dietary energy in broiler. Clearly this has both practical and economic implications. This approach to formulation of poultry diets is based on the concept that poultry tend to eat to meet their energy needs assuming that the diet is adequate in essential nutrients hill and dansky 1950. Dietary energy is supplied in broiler nutrition through different feed resources. High energy broiler starter diets resulted in extra deposition of fat holsheimer and jensen 1991 indicating the wastage of dietary energy.
At the same time excess energy intake may result in an increased fat deposition which affects meat quality and consumer health. An experiment was conducted to investigate the effects of dietary energy level on the performance and immune function of stressed broiler chickens gallus gallus domesticus a total of 96 three day old male broiler chickens ross ross were divided into two groups. Adjusting dietary energy to compensate for abnormal environmental temperatures. Dietary energy content strongly regulates feed consumption and energy is the most expensive item in poultry diets.
The study showed that low energy and low protein diets could be fed to broilers chicken as long as the energy protein ratio is maintained which will be of advantage especially as the poultry industry is facing feed crisis as a result of use of cereals for biofuel. The dietary energy level selected is often used as a basis for setting most nutrient concentrations in a diet. The most abdominal fat 2 29 average of live weight for male and females was produced by broilers offered a diet calculated to contain 3325 me kcal kg. Those who feed broiler breeders will know that in order for the energy allocation to remain constant the energy allocation of the low energy diet would need to be increased by 7 g bird per day.
Three trials with identical experimental design were conducted to examine the effects of dietary nutrient density and energy feeding programs on male broiler chickens grown to heavy weights for. Utilizing a moderate rearing temperature regimen two trials were conducted to determine the effect of dietary energy level on the amount of abdominal fat deposited when broilers are grown to equal body weight by varying growth time. Four trials were conducted to determine the feasibility of replacing fossil fuel energy with dietary energy to meet the 23 to 48 day old broiler chicken s energy requirements during abnormal cold exposure.
