| In central Brazil after soybean or other annual agricultural species is harvested, sorghum hybrids are planted in the fall in order to establish pastures for grazing animals. This study conducted for two consecutive years aimed at quantifying the contents of hydrocyanic acid in the leaves and determining plant height, forage dry matter yield and the leaf/stem ratio for sorghum hybrid 1P400 at different ages. Statistical analysis was performed by regression analysis based on plant age. Leaf HCN content decreased with plant growth, ranging from 205.0 and 230.3 mg HCN/100 g leaf DM at two weeks old to 5.9 and 6.1 mg HCN/100 g leaf DM at five weeks old in the first and second year, respectively. The average heights measured varied from 60 and 56 cm, in the 4th... |

| Objetivou-se, neste trabalho, pesquisar a relação entre os microrganismos patogênicos isolados e identificados em água utilizada na ordenha, com o isolamento e identificação dos mesmos em amostras de leite, de quartos mamários apresentando mastite clínica ou subclínica nas mesmas propriedades. Foram utilizadas 16 propriedades rurais leiteiras, escolhidas aleatoriamente, na região de Cerqueira César - SP, que utilizavam ordenha mecânica. A água utilizada na ordenha foi classificada em relação à presença de coliformes totais e fecais, como dentro dos padrões ou fora dos padrões de potabilidade humana. Nos resultados obtidos, 94% das amostras foram classificadas como fora dos padrões em relação a coliformes totais e fecais. Os microrganismos identificados... |

| Two sugarcane varieties (IAC86-2480 and IAC91-2195) combined or not with soybean hulls (SH), partially replacing corn in concentrate, were included in the diet of crossbred dairy cows to evaluate the effects on feed intake, milk production, milk composition and rumen parameters of crossbred cows. The sugarcane varieties (IAC86-2480 and IAC91-2195) and concentrate compositions (with and without SH) were analyzed in a 2 × 2 factorial arrangement. Treatments were assigned to blocks by lactation period to evaluate feed intake, milk production and milk composition. A Latin square design was used to analyze rumen parameters. Feed intake, milk production and composition were similar among treatments. Average daily feed intake was 19.93 kg DM in cows fed... |
