Item Acesso aberto (Open Access) Avaliação de sistema silvipastoril através do desempenho produtivo de búfalos manejados nas condições climáticas de Belém, Pará(Universidade Federal do Pará, 2005-06-03) CASTRO, Anderson Corrêa; LOURENÇO JÚNIOR, José de Brito; http://lattes.cnpq.br/2919433679918544A development was lead to study the relations between productive, physiological variable and of animal comfort of buffalos and factors of the physical environment, in silvipastoril system, involving african mahogany (Khaya ivorensis) and indian nim (Azadirachta indica) and intensive rotation grazing of Cynodon nlemfuensis, in the period of may of 2003 the november of 2004, in the Unit of Animal Research "Senator Alvaro Adolpho", Embrapa Eastern Amazon, Belem, Para state, in the climatic type Afi, with the rainier of december to may and less rainy time, of june to november. The area of experimental pasture, 5,4 ha, is divided in six plots, with animal permanence of five days and 25 days of rest. Had been used 26 buffaloes Murrah race, no castrated, with age between 231 and 303 days. Descriptive analysis of the experimental data was effected, for attainment of averages, shunting line standard, minimum and maximum values, correlations and variances, considering weight gain, availability and chemical composition of the pasture, physiological variable of the animals, climatic variable, development of the forest essences, Comfortal Index (CI) and Temperature – humidity Index (THI). Excellent performance of the experimental animals was observed, with 0.911 average gain of kg/day and 510 kg of final alive weight. In the periods more and less rainy, the availability, the crude protein levels of stem, leaf and entire plant and the digestibility "in vitro" of the dry and the organic matter of the pasture had been satisfactory, taking care of the minimum necessities for maintenance and detached productive performance. Occurred interferences of the meteorological variable in the cardiac beatings, respiratory frequency, rectal temperature and ruminal movement of the animals. The CI exceeded the critical level, mainly in the period less rainy, as well as the THI levels had been raised, supplanting considered of emergency, indicating the necessity of practical of manipulation of the physical environment to raise the animal performance. The development of the forest essences already supplies better ambience to the animals, in function of the shade, which contributes for the reduction of thermal stress and promotes better performance productive of the buffalos.Item Acesso aberto (Open Access) Caracterização do uso comercial e de subsistência da fauna silvestre no município de Abaetetuba, PA(Universidade Federal do Pará, 2006-02-24) BAÍA JÚNIOR, Pedro Chaves; GUIMARÃES, Diva Anelie de Araújo; http://lattes.cnpq.br/2891287458034896This work analyzed the use of local fauna by rural and urban populations in the municipality of Abaetetuba, PA (1°42.008’ W 048°54.009’), to study the feasibility of commercial breeding of wildlife in that region. Interviews were conducted with vendors and customers of the local street fair; local fauna destined for food consumption was monitored in the year 2005; riverside communities were visited and interviews conducted with the inhabitants of Capim, Xingu and Quianduba islands; captive breeding know-how of local rural producers was verified. Approximately 5,970 kg of wildlife meat belonging to eight ethno-species (opossums, deers, capybaras, paca, armadillos, black caiman, spectacled caiman e matamata) were sold at the local street faire, capybaras and caiman accounting for most of the sales, 64% and 34% respectively. Vendors were financially highly dependent on this activity, which generated a monthly income of as much as 600 reais. Consumers in Abaetetuba or near regions would purchase these products mostly due to cultural habits rather than for financial reasons. The primary subsistence activities (fishing and extraction of cabbage palm’s fruit) practiced by riverside populations have been declining or do not meet their feeding necessities. Hunting is still a common practice for some of the riverside inhabitants. 55 (38%) of them have hunted at least once in the one year period before this research was conducted and removed a total of 68 small sized animals, including opossums, agouties, armadillos, pacas, spiny rats and iguanas. Local farmers mentioned as favorable factors for breeding wildlife animals the protection of wildlife species and income generation; and as unfavorable the lack of technical and financial support, red tape, and high production costs. The formation of a participative management system, involving the community, government and private sectors is mentioned as a necessary condition for the implementation of commercial breeding of wildlife animals in this municipality.
