The aim of this study was to determine the efficiency of a bovine simulator for transrectal palpation practices. A commercial bovine simulator and four non-pregnant bovine females were used. The study included 20 and 22 students without experience in transrectal palpation who participated in the experimental (I) and control (II) group, respectively. The students of group I were trained with the simulator for the location of cervix, uterus and ovaries, while those of group II received a traditional practice, consisting of working with reproductive tracts in situ. Then, both groups were evaluated by two expert instructors in four cows regarding the correct location of the anatomical structures. The Chi square test determined differences in the degree of accuracy of the recognition of the anatomical structures between groups (p<0.05), having a better level of recognition of the structure...

The present work study aimed at evaluating the accuracy of the computerized algorithm included in the TaurusWebs ® software, which allows to calculate the percent of crude protein (% CP) in the dry matter of grasses, from images of grasslands taken by a drone with Red Green Blue – RGB- cameras. The %PC measurements calculated by the algorithm were compared to a reference, Near Infrared Reflectance Spectroscopy (NIRS), from the Corpoica (Agrosavia) Laboratory calibrated for grasses. Forty-two samples were taken for NIRS, 18 of high tropic grasses in Cundinamarca: kikuyo, Pennisetum clandestinum; false poa, Holcus lanatus; Brazilian grass, Phalaris arundinacea and 24 from the low tropics in Tolima, Colombia: pangola, Digitaria decumbens; pará, Brachiaria mutica; Bermuda, Cynodon dactylon and coloswana, Bothriochloa pertusa. The results of the NIRS were compared against the evaluations ...
