Resumo: O objetivo deste trabalho foi aplicar a metodologia de análise multicritério difusa para tomada de decisões em grupo, para determinar áreas de risco de introdução da febre aftosa na fronteira do Brasil com o Paraguai. O estudo foi conduzido em três municípios do Estado do Mato Grosso do Sul, localizados na fronteira com o Paraguai. Quatro cenários foram construídos, tendo-se aplicado os seguintes quantificadores linguísticos para descrever os fatores de risco: poucos, metade, muitos e maioria. Os três critérios considerados mais prováveis de influenciar a vulnerabilidade à introdução da febre aftosa, de acordo com a opinião dos especialistas, foram: a introdução de animais na fazenda, a distância da fronteira e a existência do tipo de propriedade assentamentos. Os mapas resultantes mostram uma forte heterogeneidade espacial no risco de introdução da febre aftosa. A metodologia utilizada traz uma nova abordagem que pode auxiliar políticas públicas no combate e na erradicação da febre aftosa.

Abstract: The objective of this work was to apply fuzzy majority multicriteria group decision-making to determine risk areas for foot-and-mouth disease (FMD) introduction along the border between Brazil and Paraguay. The study was conducted in three municipalities in the state of Mato Grosso do Sul, Brazil, located along the border with Paraguay. Four scenarios were built, applying the following linguistic quantifiers to describe risk factors: few, half, many, and most. The three criteria considered to be most likely to affect the vulnerability to introduction of FMD, according to experts' opinions, were: the introduction of animals in the farm, the distance from the border, and the type of property settlements. The resulting maps show a strong spatial heterogeneity in the risk of FMD introduction. The used methodology brings out a new approach that can be helpful to policy makers in the combat and eradication of FMD.

To verify the effects of energy supplementation and fat on follicular dynamics, metabolic profile and the production of oocytes, 15 young heifers (Bos taurus indicus) with an average age of 14 months and with an initial weight of 256.35 kg were assigned to two treatments according to weight and follicular population as evaluated by ultrasonography: in T1 (1.0 × M), animals received 100% of the energy requirements for maintenance; in T2 (1.7 × M), animals received 170% of the energy requirements for maintenance, achieved by the addition of 200 g of Megalac®. After a period of adaptation to the diet, the treatments, blood collection and follicular aspirations were started using a randomized design. The dry matter intake and weight gain were lower in the 1.0 × M group than in the 1.7 × M group. No differences were found in the plasma progesterone concentrations, albumin, glucose, urea or gonadotropin (FSH and LH) levels between the groups. The mean concentrations of cholesterol were higher in the 1.7 × M group. The total number of small (<4 mm) and medium follicles (4-8 mm) was not altered by the treatments, but the number of small follicles increased on days 1 and 2 of the estrous cycle, with higher values found in the 1.7 × M group. The average of the oocytes also increased (9.50±2.1 and 12.5±4.4 for the 1.0 × M and 1.7 × M groups, respectively). The rapid increase in the amount of energy offered in the diet changes the amount of follicles and oocytes available for follicular aspiration (OPU) in young heifers without changing their metabolic profile.
