| Since every year public and private companies bring many genotypes of maize to the market, the suitability of these genotypes for the production of silage should be evaluated. Current study evaluates the agronomic and chemical characteristics of early-normal cycle maize genotypes as well as assesses whether the genetic bases (single, double, and triple hybrids, as well as varieties and intervarietal genotypes) and the grain hardness (hard, semi-hard and dentate) modify the indication of maize genotypes for silage. The experiment was conducted at the Universidade Tecnológica Federal do Paraná, campus Dois Vizinhos, Paraná State, Brazil. Thirty-six genotypes were evaluated by a simple lattice design. Grains were harvested at the pasty to farinaceous stage... |

| This study was conducted to evaluate the use of chromium oxide and the content of fecal nitrogen to estimate forage intake by female lambs on Italian ryegrass pasture. The pasture was managed under different forage allowances (FA): 6, 9 and 12% BW. The experiment was a randomized split-split plot design, in which the forage allowances were considered as main plots, the phenological stages as subplots and methods to determine intake as sub-subplots. Forage intake, in the ryegrass vegetative stage, is independent of forage allowance. Lower allowances limit forage intake from the pre-flowering stage, while at the reproductive stage, intake was lower in FA6, intermediate in FA9 and higher in FA12. The estimation of organic matter intake by lambs on Italian... |

| Superovulatory response, production and embryo quality and the effects of seasonal changes on embryo production of Nellore cows fed on either linseed (n-3) or canola seeds (n-6) were evaluated. Sixteen Nellore cows (550 ± 48.0 kg) were fed on three diets: control diet (CON), diet with linseed (LIN) and diet with canola seed (CAN) during four seasons. There was no difference in superovulatory response and in total corpora lutea produced when diets are taken into consideration. The number of cows that responded to superovulatory treatment was higher in the winter (93.8%) than in the summer (62.5%). No difference with regard to the three diets existed on the average number of total structures (6.20, 4.96 and 6.50), unfertilized structures ( |
