Abstract: The factorial approach has been used to partition the energy requirements into maintenance, growth, and production. The coefficients determined for these purposes can be used to elaborate energy requirement models. These models consider the body weight, weight gain, egg production, and environmental temperature to determine the energy requirements for poultry. Predicting daily energy requirement models can help to establish better and more profitable feeding programs for poultry. Studies were conducted at UNESP-Jaboticabal to determine metabolizable energy (ME) requirement models for broiler breeders, laying hens, and broilers. These models were evaluated in performance trials and provided good adjustments. Therefore, they could be used to establish nutritional programs. This review aims to outline the results found at UNESP studies and to show the application of models in nutritional programs for broiler breeders, laying hens, and broilers.

Comparison of the energy utilisation of conventional and Taiwanese native male broilers
TL;DR: In this paper, the authors compared energy utilisation of conventional (CON; Arbor Acres) and Taiwanese native (NAT) male broilers, and found that CON birds had higher AME intake, q, k g and k p, but similar ME m and k f than NAT birds.

Architecture of broiler breeder energy partitioning models
01 Jan 2022
TL;DR: In this article , the authors investigated the effect of growth pattern on energy efficiency of birds and tested the effects of dividing data into daily, 4-d, weekly, 2-wk, and 3-week periods and the inclusion of random terms associated with individual maintenance ME and ADG requirements, and age on ME partitioning model fit and predictive performance.
