Indicação geográfica na conservação e agregação de valor ao gado curraleiro da comunidade kalunga

The objective of this study was to show the importance of geographical indications, as a strategy of maintaining and aggregating value to the Curraleiro cattle, and as a basis for future registration of the denomination of origin Kalunga Meat of Curraleiro, by the remaining Kalunga qui- lombo community in Cavalcante situated in the State of Goiás, Brazil. Recognition of the denomination of origin Kalunga Meat of Curraleiro, will make establishment of a modality of sustainable exploration in the Cerrado possible, as well as promote preservation of a bovine race well adapted to adverse conditions of this biome, improve their food availability and increase family income.Este trabalho objetivou mostrar a importância das indicações geográficas, como estratégia de conservação e agregação de valor ao gado Curraleiro e, propor estratégias para o futuro registro da denominação de origem Carne de Curraleiro Kalunga, pela comunidade remanescente de quilombo Kalunga do município de Cavalcante, Goiás, Brasil. O reconhecimento da denominação de origem Carne de Curraleiro Kalunga, viabilizará o estabelecimento de uma modalidade de exploração sustentável para o Cerrado, com a preservação de uma raça bovina adaptada as condições adversas deste bioma e proporcionará às famílias quilombolas, melhoria na disponibilidade de alimento e aumento da renda familiar

Serum γ-glutamyltransferase activity as an indicator of chronic liver injury in cattle with no clinical signs

This study aimed to determine the power of the serum aspartate aminotransferase (AST) and gamma-glutamyltransferasase (GGT) activities and of the albumin and cholesterol dosages for detecting hepatic histopathological injuries. A total of 220 healthy male Nelore cattle that had been extensively bred were evaluated. Blood and liver samples were collected on the day of slaughter for biochemical and histopathological tests. The results showed that the sensitivity to AST, GGT, albumin, and cholesterol tests were respectively 22.4%, 22.4%, 36%, and 37.2%. The specificity of AST, GGT, albumin, and cholesterol tests was respectively 78.8%, 90.4%, 75.6%, and 68.3%. In short, the detection of minor liver injuries through biochemical tests is limited; however, the high specificity of the GGT allows its use as an indicator of hepatic chronic injuries in cattle herds
