O objetivo deste trabalho foi avaliar medidas corporais associadas à tolerância ao calor em bovinos. Utilizaram-se 64 animais das raças naturalizadas Curraleiro (15), Mocho Nacional (7), Crioulo Lageano (7), Pantaneira (14) e Junqueira (11), e 26 animais de duas raças comerciais: Nelore (15) e Holandesa (11). Foram analisados dados sobre comprimento corporal, perímetro de canela, altura de cernelha, perímetro torácico, espessura da pele, espessura do pêlo, número de pêlos, comprimento de pêlos, pigmentação da epiderme e pelame. A raça Curraleiro apresentou menor perímetro torácico, tendo diferido das outras raças, principalmente da Mocho Nacional. As raças Crioulo Lageano e Pantaneira apresentaram maior espessura de pêlo; a raça Mocho Nacional apresentou maior espessura de pele. Os resultados obtidos demonstram que as raças Curraleiro e Junqueira são mais tolerantes ao calor que as demais raças naturalizadas.

The aim of this work was to evaluate physical aspects of heat tolerance in cattle. Sixty-four animals from five naturalized breeds were used, including Curraleiro (15 animals), Mocho Nacional (7), Crioulo Lageano (17), Pantaneira (14) and Junqueira (11), as well as twenty-six animals from two commercial breeds: Nellore (15) and Holstein (11). Measurements on shoulder height, girth, body length, cannon bone circumference, skin and hair thickness were analysed as well as hair density and hair and skin pigmentation. Girth in Curraleiro was significantly smaller than in other breeds, especially Mocho Nacional. Crioulo Lageano and Pantaneira had the thickest hair and Mocho Nacional the thickest skin. Curraleiro and Junqueira were shown to be the most heat tolerant of the naturalized breeds.

Among all activities related to the management of science and technology in Brazil, program monitoring and evaluation is certainly one of the less developed and most needed. There are no universal methodologies that can be applied. In essence programs can be evaluated by relating their achievements to pre-established goals. A second strategy is to compare programs similar in nature, utilizing as reference common indicators. Finally programs can be evaluated by their socio-economic impact comparing investments to outcomes. All strategies mentioned require appropriate program design monitoring and expert independent evaluation. In Brazil as in many other countries including developed ones this activity is complicated by the fact that programs vary widely in their scope and goals. In Brazil program designs often do not specify clearly their purposes and output indicators, many are not monitored properly which makes evaluation difficult. Consequently science and technology programs are difficult to be compared to each other, and even evaluated on the basis of pre-established goals. In PADCT monitoring and evaluation proved to be the most challenging activities. Two lessons however were learnt. One is that the process of monitoring and evaluation has to be continuously exposed to criticism to be perfected; and the second is that the evaluation process must not be exhausted shortly after investments since translation of scientific knowledge into industrial applications may prove to be a lengthy process. In this exercise we certainly do not pretend to evaluate the QEQ subprogram but to organize some of the information produced by different sources related to this subject, including the PADCT administration. We use somewhat each strategy described: compare the outputs of the QEQ to predetermined proposed goals (particularly in PADCT II), compare the QEQ to other PADCT subprograms, and specify some outputs in terms of technological and industrial applications. Finally, we utilize this opportunity to discuss science and technology M&E in general and the complexity of developing this area in Brazil.
