Parasitoses gastrintestinais e caracterização do trânsito de caprinos e ovinos comercializados na feira de animais de Tabira, Sertão de Pernambuco.

Abstract

Due to the characteristics of small ruminant production in the Brazilian Northeast, many producers use the sale of live animals in free fairs as the main way of market of their animals. Although they contribute to the economic and social development, these fairs become facilitators in the process of transmission and spread of parasitic and infectious diseases, through the large influx of animals, people and contaminated fomites. In this sense, the aim of this study was to verify the occurrence of gastrointestinal parasitism and to characterize the movement of caprine and ovine commercialized at the animals fair in Tabira, Sertão of Pernambuco. However, samples were collected from feces and blood of 84 caprine and 92 ovine commercialized between the months of November 2014 and January 2015. The caprine had a frequency of 70,24% and the ovine 78,26% of positive animals in the egg count per gram of feces (EPG). The female caprines (75,44%) and the male ovines (82,93%) adults were most affected. The caprine had higher average of EPG (6,804), a higher proportion of anemia (40,68%) and higher levels of heavy infection (11,87%) and fatal (20,35) compared to ovines. By analyzing the origin of the animals, it was observed that those from other states demonstrated to be most affected. In coproculture, it was observed that larvae of Haemonchus sp. are the most common, both in caprines (90,34%) and in ovines (91,87%). As to the movement, during the year 2014, the fair received 76,426 caprines and ovines from three states, Pernambuco (56,67%), Bahia (37,78%) and Paraíba (5,46%). Regarding the output, the animals had the states of Pernambuco (78,10%) and Paraíba (20,20%) as the main destinations. The months with higher and lower movement of caprines and ovines at the fair were April (7,608 animals) and October (5,123 animals), respectively. The Animal Transit Guides - GTA - with the purposes fattening and slaughter represented 98,88% of the total issued output guides. The animal fair of Tabira/Pernambuco represents a potential risk place for the spread of parasitic and infectious diseases of caprines and ovines, requiring an efficient monitoring on animals that enter and leave the room in order to prevent the transmission and spread diseases.
