(Sociedade Brasileira de Zootecnia, 2012-06-01)
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three ...
Feeding rate for pacu reared in net cages
The objective of this study was to evaluate the feeding management of pacu juveniles (P. mesopotamicus) under different feeding rates and its relation with productive performance, body composition and hematological ...
Taxas de alimentação para rã-touro com manejo alimentar automático e alta frequência alimentar
Three feeding rates (3, 4 and 5% of body weight/day - BW/day) with automated feed management and high feeding frequency (24 meals/day) for bullfrogs (Lithobates catesbeianus) under wet systems were evaluated in this 60-day ...
Feed digestibility and productive performance of bullfrogs fed in high and low frequency
(Elsevier B.V., 2012-01-25)
This study evaluated the effect of the feeding frequency on growth performance of bullfrogs (Lithobates catesbeianus) and established the coefficients of availability of calcium and phosphorus and the coefficient of ...
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 ...
