The use of nonlinear programming as a tool for maximum profit feed formulation of broilers
The purpose of this study was to compare linear and nonlinear programming models for feed formulation, for maximum profit, considering the real variation in the prices of the corn, soybean meal and broilers during the ...
Accuracy of nonlinear feed formulation for broiler chickens: maximising broiler profit
The modeling technique is simple, useful and practical to calculate optimum nutrient density to maximize profit margins, using nonlinear programming by predictive broiler performance. To demonstrate the influence of the ...
Bio-energy conversion cost: a new index to evaluate the bioeconomic eficiency
This study evaluated a nonlinear programming excel workbook PPFR (http://www.fmva.unesp.br/ppfr) for determining the optimum nutrient density and maximize margins. Two experiments were conducted with 240 one-day-old female ...
Effect of oscillating time of feeding and oscillating diet formulation on performance and carcass characteristics in feedlot steers
(Elsevier Inc, 2017-04)
Smaller farms often lack the control over feeding and weighing that commercial feedlots possess. The objectives of this study were to evaluate the effect of oscillating feeding time and oscillating diet formulation on ...
Effect of prey concentrations and feed training on production of Hoplias lacerdae juvenile
(Academia Brasileira de Ciências, 2015-06-01)
The aim of this work was to investigate the s of daily prey concentration during the first 15 days of active feeding of Hoplias lacerdae larvae, and the juvenile size on the feed training. In the first phase, the larvae ...
