The aim of this study was to evaluate the effects of green tea (Camellia sinensis) and oregano (Origanumvulgare) extracts on behavior, weight gain, and health indicators of dairy calves from birth to 60 days ofage. Twenty-one Jersey calves were distributed into three treatments: without additives (CON); green teaextract (GT): supply of 30 mg/kg of body weight/day; and oregano extract (OR): supply of 60 mg/kg ofbody weight/day. Observers registered animal?s behavior at 5-minute intervals from 8:00 to 16:00, threetimes a week, from day 1 to day 60 of life. The behavioral variables considered were time spent instanding, lying down, ruminating, frequency of visits to feeders, frequency of eating pasture and straw, aswell as body weight gain, body temperature, heart and respiratory rates, and health conditions. GT andOR anticipated the occurrence of thefirst rumination and the ingestion of straw in approximately 7 dayscompared with CON but did not modify the body weight gain, incidence of diarrhea, health conditions,and other behavioral variables. Supply of GT and OR stimulated the onset of dry feed intake and rumi-nation without changing performance and health status. |

This experiment was carried out with the objectives of determining repeatability coefficients, the number of harvests necessary to increase accuracy and the genotypic stability of yield characteristics in Brachiaria brizantha cultivars in the northeast region of Brazil in the period from July 2009 to March 2011. The experimental design used was completely randomized with three treatments (Brachiaria brizantha var. Marandu, Xaraés and Piatã) and three replications. Each plot was harvested seven times: five in the rainy season and two in the dry season. Immediately after each harvest, the forage was weighed and dried to obtain total, stem, leaf and dead dry matter yields. For the estimation of the repeatability coefficient, analysis of variance, principal components (correlation and covariance matrices) and structural analyses were used. The repeatability coefficients (r) obtained by the different methods, for all characteristics evaluated, varied from 0.009 to 0.837. The estimates of the repeatability coefficients obtained for all characteristics evaluated by the method of analyses of variance were almost always lower than those obtained by the other methods. By the principal components method (based on the covariance matrix), the estimates were always higher than those from other methods. Considering that levels of 80 or 90% confidence are satisfactory in the evaluation of the relative superiority of the cultivars for all the evaluated characteristics, with the exception of dead matter yield, the seven harvests are sufficient for the choice of the best cultivar to be used in the northeast region of Brazil.
