Carga parasitária e desempenho de leitões em baias na maternidade submetidas a diferentes protocolos de limpeza diária

Abstract

Brazil has a health status of its swine herd at levels much higher than other countries with higher productivity. And this is due to the performance of technicians in knowing how to intervene in the face of existing health problems. However, better zootechnical indices are still needed in the face of coccidiosis, especially those of the genus Eimeria spp. and Isospora suis that lead to clinical manifestations of yellowish and fetid diarrhea and mainly affect piglets 5 to 21 days of life, triggering underdevelopment in animals that survive the disease. Understanding this serious health problem mainly in intensive system animals, this study aimed to evaluate the difference between two daily cleaning protocols correlating them with gastrointestinal endoparasitic load and the average weight gain of feedlot confined piglets in Monte Alegre. de Minas in the state of Minas Gerais. For this, 112 animals were used during their first 21 days of age, without predisposition by sex, randomly sampled within the lots. After collection of fecal samples on the eighth day of life of the animals, they were sent to the Laboratory of Infectious Diseases of UFU and processed according to the technique by counting eggs per gram of feces (Gordon and Whitlock Method - OPG / OoPG) . By monitoring the live weight and weight gain of the animals, it was possible to identify that there were no significant differences in treatments between the rates of coccidiosis and GMD, concluding that despite the cleanliness and hygiene are very important within the pig production system, there is no need to direct extra manpower for such a task.
