The factorial approach has been used to partition the energy requirements into
maintenance, growth, and production. The coefficients determined for these purposes can …

The net energy (NE) system is often misunderstood. Dietary NE consists of 2 fractions: NE
for maintenance (NE m) and NE for production (NE p). In practical terms, NE is usually …

Achieving high lifetime productivity with broiler breeder flocks is challenging because feed
restriction intensity continues to increase due to selection for efficient, fast growing, and high …

Two experiments were conducted to develop and evaluate a model to estimate ME
requirements and determine Gompertz growth parameters for broilers. The first experiment …

Energy utilization in broilers as influenced by supplementation of enzymes containing
phytase or carbohydrase activities was investigated. Day-old male broilers (480) were …

ABSTRACT A study was performed with 2 broiler genotypes (slow and medium growth)
restricted in supplementary feed and foraging 2 different mixed vegetations (grass/clover or …

The AME and net energy (NE) values of 4 corn varieties, including 2 normal corn varieties
(Zheng Dan 958 and Xian Yu 335), and one each of waxy corn and sweet corn, and 2 …

Objective The net energy requirement for the maintenance (NE m) of broilers was
determined using regression models by the indirect calorimetry method (ICM) or the …

The aim of this work has been to assess the effect of diet density [control (CON) or 15%
diluted (DIL)] and growth curve [recommended by the genetic line (RBW) or 15% heavier …

An empirical nonlinear mixed model was derived to describe metabolizable energy (ME)
partitioning in Ross 308 broiler breeder pullets. Its coefficients described ME used for total …
