Abstract: at a time when genetically modified (gm) crops are entering the brazilian food chain, we present the findings of a study that makes use of a qualitative technique involving focal groups to look into the public's interpretation of the information available about this biotechnological innovation. this methodology produced results that revealed the interconnections drawn by the research subjects between this form of biotechnology, changes to the environment, and food production in general. the mistrust expressed about gm crops was particularly attributed by the participants to the non-availability of comprehensible information in the mass media or on product labels.

Abstract: an experiment was carried out to evaluate the effects of nebulization and artificial ventilation on the performance and skin temperature of finishing swine. castrated males and females (n = 137; landrace x large white x duroc) were allotted to two treatments by using a radomized bolck design, with eight replicates: t1 = pens without either nebulization or artificial ventilation; t2 = pens with both nebulization and artificial ventilation. there was an average of eight animals per each pen. during the experimental period, average air temperature was 26.32oc (from 23.32 to 30.72oc) and humidity, 64.5%. no signifgicant effects of treatments on average daily weight gain, average daily feed intake and feed conversion were observed. water nebulization and ventilation improved animal confort (skin temperature). the use of nebulization and ventilation is not necessary for finishing swine because, although there was less stress to animals, such management strategy did not increase their performance.

Abstract: The ammonia nitrogen (N-NH3) concentration and the pH were determined with the objective of evaluating the effect of different particle sizes (5, 7, 10mm and whole) of Tifton 85 hay in the diet of Holstein steers, with average live weight of 300kg and age of 20 months. A completely randomized design, with four replicates, in a split-plot arrangement was used. The plots were the experimental treatments (5, 7, 10mm and whole hay) and the subplots were the times of collection (0, 2, 4, 6, 8h). The use of diets including hay with particle sizes of 5mm and whole, did not affect (P>0,05) the ruminal pH; average values were 6.14 and 6.61, respectively. A linear reduction in the ruminal pH was verified in the steers fed on diets constituted by 10mm particles. For the diets including Tifton hay with particle size of 7mm, it was observed a quadratic effect, where the minimum pH (5.39) was observed 8:00 h after the feed was furnished. Concentrations of N-NH3 were affected by collection time in a quadratic way. Maximum concentrations of N-NH3, 15.55, 15.83, 18.32, 12.0 mg/100 mL, were observed at 4:28, 3:58, 2:99 and 2:80h after feeding, for the diets including Tifton 85 hay with 5, 7, 10mm and whole particle sizes, respectively. It was concluded that all diets allowed normal nycterohemeral patterns of fermentation. As concentra es de nitrogênio amoniacal (N-NH3) e pH foram determinadas objetivando avaliar o efeito de diferentes tamanhos de partículas de feno de Tifton 85 (5, 7, 10mm e inteiro) na dieta de novilhos holandeses, castrados, com peso vivo médio de 300kg e idade média de 20 meses. As determina es das concentra es de am nia ruminal (N-NH3) e o pH foram analisadas em delineamento inteiramente casualizado, em esquema de parcela subdivididas, tendo nas parcelas os tratamentos experimentais (5, 7, 10mm e feno inteiro) e nas sub-parcelas os tempos de coleta (0, 2, 4, 6, 8h), com quatro repeti es. A utiliza o de dietas constituídas com tamanhos de 5mm e partícula inteira n o afetaram o pH ruminal (P>0,05), registrando-se valores médios de pH 6,14 e 6,61, respectivamente. Verificou-se redu o linear no pH ruminal dos novilhos alimentados com a dieta constituída com partícula de 10mm e constatou-se efeito quadrático para a dieta constituída com tamanho de partícula de feno de Tifton 7mm, apresentando pH mínimo de 5,39 a 8:00 horas após o fornecimento da alimenta o. As concentra es de N-NH3 foram influenciadas quadraticamente pelos tempos de coleta, registrando concentra es máximas, de 15,55; 15,83; 18,32; 12,00mg/100mL de N-NH3 às 4:28; 3:58; 2:99 e 2:80

Abstract: The objective was to analyze nonlinear models to describe growth of lambs in three production systems. The models used were: Brody, Von Bertalanffy, Gompertz and Richards. In a 1 production system was used lambs in “creep feeding”, weaned at 60 days old and kept on pasture until they reach average 20 kg, when they were confined, slaughtered between 28 and 30 kg. In the 2 production system, lambs weaned at 90 days and kept on cultivated pasture and slaughtered between 28 and 30 kg, were used. In 3 Production System, lambs weaned at 90 days old and kept in an area of native pasture supplemented with elephant grass and leucena, in the critical period of the year and slaughtered at 28 to 30 kg were used. 17 weights of 30 animals, 10 animals for each system, from birth to 450 days, were used. Based on the study of the growth curves that are best adapted to predict the results of growth were those of Richards and Brody models, however none of the models simulated curve showed satisfactory results for the three production systems. O objetivo foi analisar modelos n o lineares para descrever o crescimento de cordeiros criados em três Sistemas de produ o. Os modelos utilizados forram: Brody, Von Bertalanffy, Richards e Gompertz. No Sistema de produ o 1 utilizaram-se cordeiros alimentados em “creep-feeding”, desmamados aos 60 dias de idade e mantidos em pastagem cultivada até atingirem media de 20 kg, quando foram confinados, e abatidos entre 28 e 30 kg. No Sistema de produ o 2 utilizaram-se cordeiros desmamados aos 90 dias e mantidos em pastagem cultivada, sendo abatidos entre 28 e 30 kg. No Sistema de produ o 3 utilizaram-se cordeiros desmamados com 90 dias de idade e mantidos em área de pastagem nativa suplementados com feno de capim elefante e de leucena no período crítico do ano e abatidos aos 28 e 30 kg. Foram utilizadas 17 pesagens de 30 animais, sendo 10 animais para cada Sistema, do nascimento aos 450 dias. Com base no estudo das curvas de crescimento, as que melhor se adaptaram para predi o dos resultados de crescimento foram as de Richards e Brody, entretanto nenhum dos modelos de curva simulados apresentou resultados satisfatórios para o Sistema de produ o 3.
