Contenido :  Eucalyptus globulus is the most important forest species in Uruguay, with more than 250,000 ha of commercial plantations. Despite its high susceptibility to diseases, production losses caused by foliar diseases have not been properly quantified in this country. This study analyzes the effects of foliar damage on growth and survival using data from a progeny test of E. globulus naturally infected by Teratosphaeria leaf disease and eucalypt rust (Puccinia psidii). The severity of leaf spots and defoliation were quantified 8 months after planting and tree growth and mortality were evaluated 2, 4 and 6 years later. The trial had a high incidence of foliar damage, with a mean leaf spot severity of 28.7% and a mean defoliation of 37%. The greatest impact of foliar damage, both on growth rate and mortality, occurred in the first 2 years after damage was assessed. During this period, leaf spot severity less than 40% and defoliation below 50% did not affect growth, while survival was affected when leaf damage was 70% or greater. By the sixth year both stem growth and survival were affected by severe foliar damage (spotting or defoliation of 80% or more), with a loss of up to 25% in diameter and an accumulated mortality over 70%. It has been established for the first time that under the intensive Uruguayan productive conditions, E. globulus trees can tolerate a relatively high degree of leaf spotting or defoliation but severe foliar damage in the first months can cause considerable pr... Presentar Todo

Título :  A survey about the number and age of bruises in bovine carcasses: effect of animal category.

Contenido :  The aim of this study was to assess the number of bruises per beef carcass and determine the age of each one considering the animal categories as underlying factor. Data were collected between January 2011 and January 2012, assessing 22234 beef carcasses. Five cattle categories were assessed: young bulls, steers, old bulls, heifers and cows. It was used the Australian Carcass Bruise Score System (with adaptations) in order to characterize the bruises. Data were analyzed by Generalized Linear Models using the GLIMMIX procedure of SAS 9.2 program. The results show high incidence of bruises on female carcasses, mostly explained by the presence of new bruises. This may be an indicator of females increased susceptibility to problems during loading, transport, unloading and handling in slaughterhouses. We conclude from the present study that there are low levels of animal welfare during pre-slaughter handling and economic loses. It should be stated that companies that are able to fulfill animal welfare demands and that ensure the final quality of their products, remain in a leading position in the market, adding ethical value to this products with consequent reduction of economical loses.
