Incidência de parasitas gastrointestinais em bovinos mantidos em sistema silvipastoril

Abstract

The cultivation of arboreal lines in the middle of pasture areas is adopted in the recovery of degraded areas, improvement of pastures and as a supplier of milder environments. However, the microclimate offered by the system can also interfere in the life cycle of gastrointestinal nematodes, since the period in which these parasites remain exposed in the environment suffers from climatic interference, based on variations in temperature, humidity and light intensity. The research measured the population of endoparasite larvae in the pastures of the livestock-forest integration installed at UNEP – Milk Bovine Culture, located in the experimental farm of the Federal University of Technology Paraná – Dois Vizinhos – PR. Where Jersey dairy females were kept in rotational pasture systems. The evaluation was carried out in two distinct areas: a conventional paddock (without shading) and a paddock with a forest pasture system (with shading); where forage samples were collected at 07:00, 09:00 and 11:00, strategic times, justified by the influence of sunrise. Both systems evaluated showed the same behavior, with respect to the presence of larvae, as a result of the time, thus the implementation of the forest pasture systems is favorable, as it will not imply changes in the calendar of application of anthelmintics in cattle and it can still result in the diversification of income from the property.
