13. Hide unhairing and characterization of commercial enzymes used in leather manufacture
The enzymatic treatment of hides in tannery processes is a promising technology. However, the reaction kinetics of commercial enzymes available to the leather industry are not fully understood and their activities have been mainly determined with model proteins such as casein as substrate, which are not of direct relevance for cattle hides. Therefore, it is

14. Os precos de bovinos no Pantanal Mato-Grossense.
The Pantanal of Mato Grosso is a plain of c. 139.000 km2, on the Brazilian central plateau, situated between 16o and 22o of latitude South and 55o and 58o longitude West, where one of the largest breeding center of beef cattle is developed. Animal husbandry is explored with minimal technical inputs within a climate of alternating water excess or sthortage. T

15. Reduction of the bull:cow ratio in the Brazilian Pantanal.
This work was conducted to study alternatives for reduction of the bull:cow ratio in the Brazilian lowland and, therefore, lower the production costs for the local beef cattle industry. The ratios 1:10, 1:25, and 1:40 were used in native pastures with a mean stocking rate of 0.27 mature animal unit per hectare over two consecutive breeding seasons. Statistic

16. Estrutura e agência no meio rural : um estudo do projeto Redes de Referência para a agricultura familiar
One of Brazil s main economic activities is the agriculture and cattle raising industry, so it is for its natural conditions or for its colonization process. Therefore this sector has intensive research and tecnology to help its development. But, the farm men not always adopt the practices from these researches because they not constantly recognize themselve

17. A atuação do complexo agroindustrial canavieiro em rede : o exemplo de Nova Luzitânia-SP
The aim of this research was to analise the evolution of the production processes and work at the mesoregions of São José do Rio Preto and Araçatuba, mainly at the microregions of Auriflama and Araçatuba specifying the city of Nova Luzitânia. In these was developed the Agro-industrial Complex operating through the geographics nets. In order to better un

18. Meiotic chromosomes and nucleolar behavior in testicular cells of the grassland spittlebugs Deois flavopicta, Mahanarva fimbriolata and Notozulia entreriana (Hemiptera, Auchenorrhyncha)
Spittlebugs annually infest pastures and cause severe damage, representing a serious problem for the tropical American beef cattle industry. Spittlebugs are an important biotic constraint to forage production and there is a lack of cytogenetic data for this group of insects. For these reasons, we conducted this work, in which the spermatogenesis and nucleola

19. A bovinocultura de corte do estado de Mato Grosso do Sul : evolução e competitividade / Beef cattle in Mato Grosso do Sul state, Brazil : evolution and competitiveness
This dissertation is an attempt to characterize beef cattle raising production in Mato Grosso do Sul - a state which is currently the largest producer and supplier of beef in the country - and discuss the main factors responsible for its development. The study followed two analytical axes: it traces back the evolution of cattle-raising in the state during th

20. Economic and environmental analysis on intensifying beef cattle production in the Brazilian Center-West / Análise econômico-ambiental da intensificação da pecuária de corte no Centro-Oeste brasileiro
The beef cattle industry that generates jobs and income for billions of people around the world has been drawing attention over negative impacts caused to the environment. This is due to the extensive production system adopted in most producing areas, which consumes a large amount of natural resources such as land and water. In recent decades, the growing co

21. Coordination failures in complex agrisystems: an application on the beef agro industry / Falhas de coordenação em sistemas agroindustriais complexos: uma aplicação na agroindústria da carne bovina
A questão central dessa tese é entender as razões e a natureza das falhas de coordenação em sistemas agroindustriais complexos. A temática de falhas de coordenação é um problema multifacetado e complexo, representando um desafio para pesquisadores. Uma observação crítica das organizações leva à conclusão de que as falhas organizacionais, face

24. INVESTIGATIONS ON BIOLOGICAL INDICATORS FOR FEED EFFICIENCY IN CATTLE
This thesis aimed to identify potential indicators for feed efficiency and also better understand the biological factors influencing the efficiency of feed utilization by cattle. The growing focus of the beef industry on feed efficiency has resulted in the demand for more reliable low-cost alternatives for predicting feed efficiency. Many researchers have in
