Influência do parasitismo gastrintestinal sobre sinais clínicos, valores de hematócrito (HT) e pproteína plasmática total (PPT), em caprinos e ovinos criados no semi-árido do estado Pernambuco

Abstract

It was objectified with this work to search the parasitism frequncy related by farmers and to identify the possible association between the clinical signals, hematological alterations and parasitic infection of goats and sheeps livestock of two cities on Pernambuco State semiarid region, as a part of this State Program of caprine and ovine healthy. A total of 263 goats and 98 sheeps of different breed, young and adults, male and female were used to clinical evaluation and blood and feces sample gasthering whose therefore were send to laboratorial analysis for hematocrit (Ht) measurement, total plasmatic protein dosage (TPP), nematode faecal egg counts (FECs) and fecal culture. The results were evaluated through descriptive association analysis using the EpiInfo 6.02 Statistic Program. Anemia was the most frequent problem, related for 50% of the interviewed farmers, followed by diarrhea with 47,6% of the reports. At about 27% of the ovine samples showed low values of Ht (17% - 23%) whose more than 77% had no clinical disturbs. In the same way, from 25% of caprine samples with low Ht values (8% - 18%) at about68% showed no clinical signs. Just 14,28% of the sheep samples had low TPP values (5 – 5,8 g/dl) whose 85% had no clinical altertions. On caprine population studied, only 5,32% had low TPP values (3,4 – 5,8 g/dl) and of them 85% were considered clinically healthy. Fecal culture was positive for 46,35% of sheep whose at least 57% were considered clinically healthy by clinical evaluation. The OPG was positive for 60% of the goats samples and 73% of them shoned no clinical disturbs. Hematocrit low values (8 – 18%) were observed in 36,58% of sheep and 22% of goats samples in the same way, low values were observed on TPP dosage (3,4 – 5,8 g/dl) in 19,51%. Of ovine and 5,51% of caprine samples, with no dependence of FECs results.The qualitative evaluation (clinical parameters) were not decisive in the identification of parasitized animals and the quantitative analysis (HT, TPP and OPG) were not conclusive for indicate animal illness. It is possible to conclude that rusticity and resistance are important characteristics on the investigated flock.
