Effects of calving number's on pelvimetrics traits in dans and external mesuraments calves in Nelore breed
Keywords:Pelvimetry, Pelviology, Nelore
AbstractExternal and internal pelvic, body measurements and external measurements of calves were in vivo accomplished in 142 females of bovine Nelore breed, using standard scale and Rice pelvimeter. For comparison of the different measurements, the animals were divided in three groups, according to the occurrence and frequency of births (nuliparus, primiparus and multiparus). Significant differences (P<0,05), detect by analyses of variance, among the three groups they were observed for variables: ilioisquiatic, medium bi-iliac, sacro-pubic, internal bi-isquiatic, ellipse area, rectangle area, and thoracic perimeter of calves. The estimates of correlations among external and internal pelvic measurements, among external pelvic measurements with external measurements of calves and internal pelvic measurements and external measurements of calves were, in general, of low, indicating absence of associations among the different measures.
