Implementation Of Net Energy Evaluating System In Layer Hens: Validation By Performance And Egg Quality
Tuesday 10th April 2018.
The feed cost accounts for most of the production costs. The costs of ingredients supplying energy for the animal contribute the largest portion of total diet costs. The knowledge about the diets ingredients contents is a necessity for the nutritionist to formulate diets meeting the animal’s requirements and optimizing their optimizing their production. Different feeds’ energy evaluating system is available for mono gastric animals, pigs, and poultry, in terms of digestible energy (DE), apparent metabolisable energy (AME), and net energy (NE). The NE considers that part of energy wastes dissipating as heat through the digestion and metabolism. So, hypothetically, formulating the diets according to the real available amount of energy, NE, is better than the current feed formulating system, AME. In our experiment at UNE with big numbers of layers, we formulated diets on different feeds’ energy evaluating system to see whether is any beneficial effects on the birds’ performance, egg quality parameters, and economics. The results are promising and I am looking forward to seeing you on my seminar day!
