Energy and protein requirements of young Holstein calves in tropical condition. Our objective was to estimate the energy and protein requirements of Holstein young calves up to 87 days old. Forty-two Holstein calves aged 4 days were used. From these, ten were randomly selected an... ... Repository: BDPA Publication year: 2016
Energy requirements for pregnant dairy cows. This study aimed to estimate energy requirements of pregnant Holstein × Gyr cows. Different planes of nutrition were established by two feeding regimens: ad libitum or maintenance. Sixty-two nonlactat... ... Repository: BDPA Publication year: 2020
Digestible energy, protein, and energy-protein ratio requirements of Pseudoplatystoma reticulatum. The use of novel aquaculture species depends on the determination of their nutritional requirements. This study aims at determining dietary protein, energy, and protein?energy ratio requirements of ju... ... Repository: BDPA Publication year: 2020
Nutritional requirements of energy, protein and macrominerals for maintenance and weight gain of young crossbred Nellore × Holstein bulls on pasture. The objective of this study was to estimate requirements of energy, protein and macrominerals of young Nellore/Holstein crossbreds bulls supplemented on pastures of Brachiaria decumbens Stapf. Thirty-... ... Repository: BDPA Publication year: 2012
Energy requirement of Holstein calves. Repository: BDPA Publication year: 2013
Energy requirements of Holstein, Gyr, and Holstein x Gyr crossbred heifers using the respirometry technique. 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
Estimates of energy requirements for maintenance and gain of Holstein x Gyr crossbred yearling bulls using comparative slaughter and respiration chambers techniques. Brazil has its own nutrient requirement system for cattle; however, information about crossbred cattle is little due to the database being constituted of zebu cattle in general. Regarding energy requi... ... Repository: BDPA Publication year: 2015
Metabolizable energy requirement for maintance of free-range laying hens. Repository: BDPA Publication year: 2012
Different methods and times to estimate heat production in sheep fed with sunflower meal. 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... ...

The modeling and simulation of a smoke-free firewood furnace designed for indirect heating adapted to mixing heating configuration. ABSTRACT: The use of wood furnaces for thermal energy applications in drying is common among coffee growers in Brazil. However, incomplete combustion of firewood and excessive use of damaged furnaces... ... Repository: BDPA Publication year: 2024
