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 objective of this study was to evaluate the effect of non-genetic factors on the characteristics of pre-weaning growth in sheep under tropical conditions. The sex of the lamb, the type of birth (single, multiple) and parity number on the birth weight, weaning weight and preweaning daily gain of 52 wool biotype lambs were evaluated. The lambs were weighed weekly from birth to week 12 (weaning). The sex of lambs did not have a significant effect on the variables evaluated. Lambs from mothers of third lambing had a higher preweaning daily gain than lambs from mothers of first lambing (p<0.05). Singleborn were heavier at birth and at weaning than lambs born as twins (p<0.05). It is concluded that the type of birth is the factor that mainly affects the characteristics of preweaning growth and that the sex of the offspring and lambing number do not significantly affect the growth per...
