ABSTRACT The objective of this study was to determine prediction equations to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) values of animal meals used in broiler diets through meta-analysis. A bibliographic review was undertaken with studies conducted in Brazil from 2000 to 2016 to catalogue information on AMEn values and the following chemical elements in the composition of the feedstuffs: crude protein (CP), ether extract (EE), gross energy (GE), mineral matter (MM), calcium (Ca), and phosphorus (P). Groups were also […]

Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became more accessible and powerful, scientists began to conceptualize and develop mathematical nutrition models, and to program them into computers to assist with ration balancing […]

This study was conducted using data from single crosses (partial diallel) of male lines, group I (LL, TL, ZL, TT, LT, ZT, ZZ, LZ, TL), female lines, group II (PP, KP, VP, KK, PK, VK, VV, PV, KV), besides two control lines (LLc and PPc). A completely randomized block design, with three replicales, 82 single crosses treatments with nine females for experimental unit was used in the analyses. The production traits analyzed, eleven total, were: fertility at 32nd, 38th, 42nd […]
