The physiological changes that occur at puberty in heifers are objectives of study in order to better understand this phenomenon and to identify alternatives to achieve greater sexual precocity. Among the most important factors that influence puberty the leptin hormone and its receptor can be highlighted, as they are factors that perform communication between the nutritional status and the reproductive axis, and its participation in reproductive physiology is not fully understood. Therefore, the aim of this study was to determine the serum profile of the leptin hormone, to identify polymorphisms at exon 20 of the leptin receptor and associate them with the occurrence of puberty in heifers raised on pasture. We followed 56 heifers for 17 months and carried...

Current paper evaluates the performance of confined beef cattle supplemented with amylolytic enzyme complex produced by fungus Aspergillus awamori and a commercial product containing multienzyme complex, yeast and MOS. Treatments comprised control (basal diet composed of 16% Mombasa grass silage, 66% ground corn, 3% vitamin nuclear mineral and 15% cottonseed meal), amylase treatment (control diet with the addition of 48.7 saccharifying units kg-1 diet) and compound treatment (control diet with the addition of enzymatic complex composed of 83.2 saccharifying units, 8.8 fibrolytic units, 0.05 g of mannan oligosaccharides and 0.2 g of inactivated yeast Kg-1 of the dry matter diet). The addition of products did not significantly increase daily weight gain,...
