RESUMO
Surgical intervention for umbilical diseases in calves, when indicated, is a complementary and indispensable therapeutic resource for the treatment of umbilical conditions and is commonly performed using celiotomy. However, laparoscopy has demonstrated feasibility in many diagnostic and therapeutic procedures. The aim of this study was to assess the feasibility of the techniques and the surgical time of laparoscopy and celiotomy used in intra-abdominal resection of the umbilical vein and urachus of bovine fetuses (cadavers). Resection of the umbilical vein and urachus using laparoscopy and celiotomy was performed in 26 anatomical specimens (bovine fetuses obtained from an official slaughterhouse). Resection of umbilical structures was feasible with both techniques, but shorter surgical time and minimal tissue damage were achieved using laparoscopy. Laparoscopy requires specialized training and appropriate instruments and is an important tool for diagnostic and therapeutic exploration of the umbilical structures, liver, bladder, and associated/adjacent structures.

The use of frozen semen for PIVE is not fully utilized, as usually using a full dose of semen being wasteda large number of sperm that could be used in other PIVE, for these reasons, the objective of this work was toevaluate the fractionation of 0.25 ml straws in frozen bovine semen doses, divided into four equal sections forlater use in IVF technique in order to avoid wasting sperm present in the straw. Motility, vigor and spermconcentration analyzes were performed. There was observed no effect of vane fractionation process on spermparameters evaluated, such as motility 58,75%±7,6, vigor 2,75±1,6, and spermatic concentration average(3,7x106) between the sectioned parts. Thus, it is concluded that the semen dose fractionation method ofcryopreserved bull into four sections is viable for in vitro fertilization techniques, provided that there is nocompromise on the number and viability of sperm cells.
