Bioenergetic potential and genetic diversity of elephantgrass via morpho-agronomic and biomass quality traits. Author(s): MACHADO, J. C.; CARNEIRO, J. da C.; RESENDE, M. D. V. de; LEDO, F. J. da S. Elephantgrass has been a notable option as bioenergy plant. However, for its bioenergetic use, the quantification of genetic diversity based on biomass quality traits has not been commonly reported in... ... Repository: BDPA Publication year: 2017
Shadowing of a bioenergetic species in soybean development: an analysis of the feasibility potential of this integration. Repository: BDPA Publication year: 2023
Modeling of waste outputs in the aquatic environment from a commercial cage farm under neotropical climate conditions. Abstract: The present study used a bioenergetics modeling approach to estimate the solid and dissolved waste outputs of a Nile tilapia Oreochromis niloticus net-cage farm. H... ...

Different methods and times to estimate heat production in sheep fed with sunflower meal. Author(s): MACHADO, F. S. The objective of this study was to assess the oxygen pulse and heart rate method (O2 P-HR) using a respiration chamber at different measurement times for estimate the heat production (HP) of lambs fed... ...

Relationship between feed efficiency indexes and performance, body measurements, digestibility, energy partitioning, and nitrogen partitioning in pre-weaning dairy heifers. Author(s): MACHADO, F. S.; PEREIRA, L. G. R.; TOMICH, T. R.; CAMPOS, M. M. The objectives of this study were: 1) to classify animals into groups of high and low feed efficiency using two feed efficiency indexes (Residual feed intake (RFI) and residual feed intake and body we... ...

Energy requirements of Holstein, Gyr, and Holstein x Gyr crossbred heifers using the respirometry technique. Author(s): MACHADO, F. S.; CAMPOS, M. M.; TOMICH, T. R.; PEREIRA, L. G. R. We aimed to determine the energy requirements for maintenance and gain of 18 prepubertal dairy heifers of three breed compositions (BC; Holstein, Gyr, and Holstein × Gyr). Diets were formulated for ga... ... Repository: BDPA Publication year: 2022
Are dairy cows with a more reactive temperament less efficient in energetic metabolism and do they produce more enteric methane? Author(s): CAMPOS, M. M.; PEREIRA, L. G. R.; MACHADO, F. S.; TOMICH, T. R. It remains unknown whether dairy cows with more reactive temperament produce more enteric methane (CH4) and are less bioenergetically efficient than the calmer ones. The objectives of this study were... ... Repository: BDPA Publication year: 2021
Unraveling candidate genes underlying biomass digestibility in elephant grass (Cenchrus purpureus). Author(s): RESENDE, M. D. V. de; CARNEIRO, J. da C.; AZEVEDO, A. L. S.; PEREIRA, J. F.; MACHADO, J. C. Background: Elephant grass [Cenchrus purpureus (Schumach.) Morrone] is used for bioenergy and animal feed. In order to identify candidate genes that could be exploited for marker-assisted selection in... ... Repository: BDPA Publication year: 2019
Quantifcation of methane emitted by ruminants: a review of methods. The contribution of greenhouse gas (GHG) emissions from ruminant production systems varies between countries and between regions within individual countries. The appropriate quantifcation of GHG emiss... ... Repository: BDPA Publication year: 2022
