In previous research, feed intake and egg production parameters were the most common response criteria that researchers used to measure energy responses in poultry.
as part of the renewable fuels' standard. In the quest to identify and validate alternatives to corn as the primary energy source in laying hen diets, a more wholistic approach to laying hen metabolism was investigated.
What resulted was more than a decade of research conducted by Persia and a team of graduate and undergraduate students in the School of Animal Sciences. What they discovered supported their line of thinking. At least over the short term, the amount of energy fed to hens doesn't affect the number of eggs produced. Hens will produce eggs as long as they have enough fatty tissue and mass in their reserves to supply the energy to produce them.and fatty tissue before more direct performance responses are observed," Persia said."Therefore, hen body weight and composition can be used as a more sensitive measurement of hen energy status than egg production or feed efficiency.
More recently, the cost of dietary oil, the second leading energy component of a diet, has increased with additional biodiesel production. As so, Persia and his team conducted an experiment to evaluate the effects of varying dietary energy on the performance andA total of 252 hens were fed one of seven experimental diets ranging in dietary energy from 2,750 to 3,050 kilocalories. Egg production, energy intake, feed intake, egg weight, egg mass, and feed efficiency were calculated.
Results indicated that dietary energy intake impacted the hens' total carcass mass and carcass fat mass before altering the number of eggs they produced.
