Abstract

TSE, M.C.P. et al. Prenatal growth of body and some organs of crossbred Zebu collected from São Paulo slaughterhouse. Arq. Bras. Med. Vet. Zootec. [online]. 1999, vol.51, n.4, pp.359-362. ISSN 1678-4162.  https://doi.org/10.1590/S0102-09351999000400012.

A total of 196 fetuses of crossbred Zebu between 106 to 246mm in length collected from a slaughterhouse in São Paulo, Brazil, and divided into groups of 10mm size differences intervals into 15 classes were measured and weighed. Liver, heart and lungs were also removed and weighed. In order to select the method of evaluation of growth several mathematical functions were applied. Among significant equations the monologarithmic function was selected. Furthermore, the fetuses in similar conditions of length and weight were compared with racially pure fetuses.

Keywords : Cattle; crossbred Zebu; fetal development; monologarithmic function.
