Energy and protein requirements of young Holstein calves in tropical condition. Author(s): CAMPOS, M. M. 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. Author(s): CAMPOS, M. M.; MACHADO, F. S. 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. Author(s): SILVA, T. S. de C. 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. Author(s): SALES, M. F. L. 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. Author(s): MACHADO, F. S. Repository: BDPA Publication year: 2013
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
Estimates of energy requirements for maintenance and gain of Holstein x Gyr crossbred yearling bulls using comparative slaughter and respiration chambers techniques. Author(s): MACHADO, F. S.; TOMICH, T. R.; PEREIRA, L. G. R.; CAMPOS, M. M. 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
