B.; SANTOS, M.; SANTANA, T. dos S.; COSTA, W. C. C. da; FERREIRA, L. C. L; NOGUEIRA, E.; PFEIFER, L. F. M.; STERZA, F. de A. M. The aim of this study was to evaluate the influence of the FTAI-calving interval, according to animal category, on the fertility of beef cows. Early Nelore primiparous cows (n = 879; 24 ± 3.3 months;... ... Repository: BDPA Publication year: 2024
Post-weaning conditioning as a technique to increase growth performance of beef calves in the dry season. Author(s): GOMES, R. da C.; NEVES, A. P.; ARAÚJO, T. A. C. de; SILVA, A. M. da; LATTA, K. I.; MENEZES, G. R. de O.; MONTAGNER, D. B.; TORRES JUNIOR, R. A. de A. Weaning may cause negative effects on growth performance of the weaned calf, mainly if it coincided with the dry season when forage presents low nutritional value. The aim was to evaluate the effect o... ... Repository: BDPA Publication year: 2018
Effect of calving to timed artificial insemination interval on fertility of beef cows. Author(s): TOMAZI FILHO, J.; PFEIFER, L. F. M.; HOEFLE, C. A.; RODRIGUES, M. F.; FERREIRA, R. The objectives of this study were to determine the effect of calving to timed artificial insemination (C-TAI) interval on fertility of Bos taurus and Bos indicus cows and to determine the best C-TAI i... ...
