| Heat stress negatively afects livestock, with undesirable efects on animals? production and reproduction. Temperature and humidity index (THI) is a climatic variable used worldwide to study the efect of heat stress on farm animals. Temperature and humidity data can be obtained in Brazil through the National Institute of Meteorology (INMET), but complete data may not be available due to temporary failures on weather stations. An alternative to obtaining meteorological data is the National Aeronautics and Space Administration Prediction of Worldwide Energy Resources (NASA POWER) satellite-based weather system. We aimed to compare THI estimates obtained from INMET weather stations and NASA POWER meteorological information sources using Pearson correlation and... |

| Resumo: O objetivo do presente estudo foi avaliar as associações entre medidas morfométricas e ultrassonográficas e a produção de leite em caprinos, para identificar animais com melhor eficiência de produção. Foram utilizadas trinta e seis cabras, sendo 18 da raça Saa-nen e 18 da raça Anglo-nubiana. As características morfológicas mensuradas foram pro-fundidade do úbere (PU), largura do úbere (LAR), distância do teto ao solo (DTS), dis-tância entre tetos (DET), comprimento (CT) e diâmetro do teto (DT). As características avaliadas por ultrassonografia foram comprimento do canal do teto (CCT), diâmetro do teto (DTU), espessura da parede do teto (ESPT), área da cisterna do teto (ARCT) e área da cisterna da glândula (ARCG). A produção de leite diária (PL) foi... |

| Abstract This study evaluated the role of dry fruits as a source of fungal contaminants or functional compounds. Dry apple, apricot, candied fruits, prune, and white and black raisin were evaluated regarding patulin and ergosterol content, centesimal composition, pH, acidity, pectin, and phenolic profile. The ergosterol was detected in 38% of the samples and patulin (PAT) in 89%, the apricot samples stood out most by contaminant level. Apricot, candied fruit, and prunes presented moisture values beyond the other dry fruits. The pH ranged from 3.8 to 4.6; acidity from 0.1 to 1.0%; sugar content from 1.7 to 5.5%; and levels of soluble and insoluble pectin from 1.6 to 5.1% and 10.9% to 27.3%, respectively. The apples showed a higher content of free phenolic... |

| ABSTRACT: The objective of this study was to evaluate, through partial correlation analysis, the degree of association between herbage accumulation and morphogenetic traits of ‘Tanzania’ grass (Panicum maximum Jacq.) defoliated with 95% of light interception and fertilized with nitrogen, under different planting densities. The experiment was carried out in a randomized complete design with 12 treatments and two replicates, in a 4 × 3 factorial arrangement consisting of four nitrogen rates (0, 80, 160, and 320kg ha-1 Yr-1) and three planting densities (9, 25, and 49 plants m-2). Harvests were performed at 25cm above the soil, when the plots intercepted 95% of the incident light. The simple correlation coefficients between herbage accumulation and leaf and... |

| Abstract By considering the few studies related to pineapple cv. Vitória, to know the relationships between the physical and chemical characteristics of the fruits, and they with the “D” leaf, is fundamental. The objective of this work was to evaluate the relationships between “D” leaf, with the physical and chemical characteristics of fruits of pineapple cv. Vitória, under the edaphoclimatic conditions in the North of the State of Espírito Santo. The experiment was carried out in a complete randomized block design in split-plot arrangement with four replications. The data obtained from 433 individually evaluated fruits were analyzed, as it follows: 84 at planting in July and induction at 8 months; 98 at planting in July and induction at 10 months; 84 at... |
