Identifying efficient animals is an alternative to reduce food costs and natural resources used in farming. The objective of this study was to identify the correlation between Residual Feed intake (RFI) and Daily Water Consumption (DWC) in Nellore cattle. The work was realized at Núcleo Regional of Embrapa Cerrados, in June, 2017. Were used 44 bulls, aged between 18 and 21 months and initial weight of 455 kg. The diet was given twice daily, with corn silage: concentrate of 60:40. Feed intake was obtained in the feeders of Intergado System. Daily water consumption was measured by water drinked in electronic drinking fountains coupled to the automatic scales (Intergado System TM) plus water from feed. The RFI was calculated by means of the difference between the observed dry matter intake (DMIobs) and the expected dry matter intake (DMIexp) based on live weight (LW) and average daily gain (ADG). The descriptive statistics, comparison of means by Tukey test at 5% probability and Pearson correlations for the study traits were performed using software R (version 3.3.2). Groups of high, low and mean RFI were formed with one Standar Desviation of the mean RFI. The water consumption averaged 38.9 L / day, with a standard deviation of 6.1 L / d, and a minimum value of 30.0 and a maximum of 62.2 L / day. The RFI had zero and standard deviation of 1.01 kg / d, with a minimum value of -2.38 and a maximum of 2.7. The correlation between RFI and DWC was .24, being considered of low magnitude. It was not observed differences between RFI groups, with means of 37.0, 38.8 and 42.3 L / d, respectively, to Low, Medium and High RFI Groups. We concluded that water intake was not correlated with RFI in Nellore bulls confined in the early dry season of Brazil.

ABSTRACT: Sweet maize seeds present lower physiologic quality, when compared to regular maize seeds, due to the influence of several features, such as the seed size and shape. Thus, this study aimed at evaluating the seed physiologic quality of two sweet maize cultivars (BR-401 and BR-402), separately classified according to thickness, by using slotted screen sieves (8/64? x 3/4, 9/64? x 3/4, 10/64? x 3/4, 11/64? x 3/4, 12/64? x 3/4 and 13/64? x 3/4), and width, with round screen sieves (17/64?, 18/64?, 19/64?, 20/64?, 21/64? and 22/64?). For each cultivar, sorted lots were compared with the unrated batch, following a completely randomized design, in a 2x7 factorial scheme, with four replications. The biometric parameters evaluated were sieve retention, 100 seeds weight and water content. The physiologic quality was determined according to the first counting, germination, cold test, accelerated aging, electric conductivity and seedling emergence in the field. The classification with sieves improved the physiologic quality of sweet maize seeds. Seeds with intermediate thickness, for both cultivars, generally presented greater vigor. Concerning width, larger seeds, for the BR-401 cultivar, and intermediate seeds, for the BR-402 cultivar, showed better physiologic quality. RESUMO: Esse tipo de milho difere do comum por apresentar elevado teor de açúcares no endosperma, principalmente no estádio imaturo. A ação de alelos de genes mutantes, destacando-se o sugary (su1), brittle (bt2) e shrunken (sh2), é responsável pela mudança no metabolismo deste vegetal, pois bloqueia a conversão de açúcares em amido (Araújo et al. 2006). As sementes de milho doce apresentam qualidade fisiológica inferior à das sementes de milho comum, devido à influência de várias características, como o tamanho e a forma das sementes. Diante disto, este estudo objetivou avaliar a qualidade fisiológica de sementes de duas cultivares de milho doce (BR-401 e BR-402), classificadas, separadamente, quanto à espessura, por meio de peneiras de crivos oblongos (8/64? x 3/4, 9/64? x 3/4, 10/64? x 3/4, 11/64? x 3/4, 12/64? x 3/4 e 13/64? x 3/4), e quanto à largura, em peneiras de crivos redondos (17/64?, 18/64?, 19/64?, 20/64?, 21/64? e 22/64?). Para cada cultivar, os lotes classificados foram comparados com o lote sem classificação, seguindo delineamento inteiramente causalizado, em esquema fatorial 2x7, com quatro repetições. Os parâmetros biométricos avaliados foram: retenção em peneira, massa de 100 sementes e teor de água. A qualidade fisiológica foi determinada por meio da primeira contagem, germinação, teste de frio, envelhecimento acelerado, condutividade elétrica e emergência de plântulas no campo. A classificação em peneiras melhorou a qualidade fisiológica das sementes de milho doce. As sementes com espessura intermediária, para ambas as cultivares, em geral, apresentaram maior vigor. Quanto à largura, sementes maiores, para a cultivar BR-401, e de largura intermediária, para a cultivar BR-402, apresentaram melhor qualidade fisiológica.
