Fine mapping of tick resistance QTL on BTA23 in Gyr x Holstein population. Author(s): MACHADO, M. A.; AZEVEDO, A. L. S.; GASPARINI, C.; BERNARDO, K. B.; REIS, D. R. de L.; PEIXOTO, M. G. C. D.; SILVA, M. V. G. B.; REGITANO, L. C. de A.; VERNEQUE, R. da S. The objective of this work was to fine map a QTL associated with tick resistance/susceptibility previously detected on BTA 23 in a Gyr x Holstein F2 population. In order to reduce the confidence inter... ... Repository: BDPA Publication year: 2011
Energy and protein requirements of young Holstein calves in tropical condition. Author(s): RODRIGUES, J. P. P.; LIMA, J. C. M.; CASTRO, M. M. D.; VALADARES FILHO, S. de C.; CAMPOS, M. M.; CHIZOTTI, M. L.; MARCONDES, M. I. 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
Intensive grazing system increases milk productivity of Holstein and Jersey-Holstein crossbred dairy cows. Author(s): OLIVEIRA, P. P. A.; RODRIGUES, P. H. M.; PRAES, M. F. F. M.; LEMES, A. P.; PEDROSO, A. de F.; ALVES, T. C. In Brazil, despite the lack of accurate statistics on the contribution of each type of system in total milk production, it is known that pastures represent the main feed source in most production syst... ...

Nutritional requirements of energy, protein and macrominerals for maintenance and weight gain of young crossbred Nellore × Holstein bulls on pasture. Author(s): PORTO, M. O.; PAULINO, M. F.; VALADARES FILHO, S. de C.; DETMANN, E.; CAVALI, J.; SALES, M. F. L.; VALENTE, E. E. L.; COUTO, V. R. M. 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

Genetic parameters for type traits in Holstein cows in Brazil. Author(s): CAMPOS, R. V.; COBUCI, J. A.; COSTA, C. N.; BRACCINI NETO, J. Data from 26,558 Holstein cows in 802 herds were used to estimate genetic, residual and phenotypic parameters for 22 type traits. The model included the fixed effects of herd-year, period of classific... ... Repository: BDPA Publication year: 2012
