Prevalência e fatores de risco da neosporose bovina na microrregião de Teresina-PI / Prevalence and bovine neosporosis risk factors in the micro region of Teresina - PI

A biggest problem in breeding cattle are fetal and newborn losses in the herd, which cause manyeconomic losses to producers. These losses may be related to the protozoan Neospora caninum, which causesthe disease known as neosporosis. The present study was carried in 14 production units of cattle in themunicipalities near from Teresina. Blood collection was performed by jugular venipuncture, using a 15 mlcollection tubes without anticoagulant. For the identification of anti-N antibodies. caninum used the technique ofindirect immunofluorescence (IIF) for detection of antibodies of the IgG class. The prevalence of infection by theprotozoan parasite for the samples examined was 15,23% (64/420) of seropositive animals and 84,76%(356/420) seronegative, distributed in 100% (14/14) of the herds studied. Also demonstrated in this study, theoccurrence of at least one animal tested positive for N. caninum, in each flock evaluated.(AU)

Prevalência e fatores de risco da toxoplasmose bovina na microrregião de Teresina PI / Prevalence and bovine toxoplasmosis risk factors in the micro region of Teresina - PI

Toxoplasmosis is caused by the protozoan Toxoplasma gondii, a cosmopolitan zoonosis that affectsseveral warm-blooded animal species. The main transmission routes of T. gondii are fecal-oral, carnivorous andcongenital.Congenital transmission, when the parasite reaches the concept via the transplanted route, is oftenmore severe, which transmits tachyzoites to the fetus.. The present study was carried in 13 production units ofcattle in the municipalities near from Teresina. Blood collection was performed by jugular venipuncture, using a15 ml collection tubes without anticoagulant. For the identification of. anti-T. gondii used the technique ofindirect immunofluorescence (IIF) for detection of antibodies of the IgG class. The prevalence of infection by theprotozoan parasite for the samples examined was 17,44% (68/390) of seropositive animals and 82,56%(322/390) seronegative, distributed in 100% (13/13) of the herds studied. Also demonstrated in this study, theoccurrence of at least one animal tested positive for T. gondii, in each flock evaluated.(AU)

Prevalência de anticorpos anti-Vírus da Diarréia Viral Bovina em bovinos da microrregião de Teresina, Estado do Piauí, Brasil / Prevalence of Bovine Viral Diarrhea Virus antibodies in cattle of the microregion of Teresina, Piauí State, Brazil

One of the most important diseases and therefore worth mentioning in cutting cattle and milk for causinggreat productive and reproductive losses and bovine viral diarrhea, infectious disease caused by the Flaviviridaefamily of viruses and pestiviruses Gender, this called Viral Diarrhoea Virus Bovina (BVDV). animals affected bythis disease are pathological changes in digestive, reproductive, respiratory, hematopoietic, and may developmucosal disease and severe immunosuppression. As a result of this work was to study the prevalence of anti-virusbovine viral diarrhea antibodies in cattle the Microregion of Teresina, state of Piaui, Brazil.(AU)

Influência do nível de infestação parasitaria da cabra sobre o desempenho da cria durante a fase de lactação / Parasitic infestation level of influence of goat on the performance of the offspring during lactation phase

In goat gastrointestinal parasitism is a major limitation of production. In this perspective analyzed tocharacterize the phenotypic variability of gastrointestinal parasitism resistance and associated with productiveand reproductive performance of the arrays. The goats were divided into two groups, where in a goats werelactating and the other in the breeding season, which was made measurements according to the physiologicalstage of the goats. It was concluded that the herd is presented with continuous infestation by worms in the studyperiod and no group stood out from the others in the analyzed characteristics.(AU)

Importance of the parturition period of goats inside birth season / Importância do período de parto de cabras dentro da estação de nascimentos

In Northeast of Brazil the time of mating and calving of the matrices are determining factors in the herdproductivity. This research analyzed in Anglonubiano breed the importance of birth order within the birth station inthe herd, with the goat characteristics and the development of the offspring to weaning. The goats were divided intotwo groups, in a way that when a group of matrices were in breeding season, in the other group it has alredyoccurred. A database containing information such as goats age, birth interval and the previous (month), OPG,body Score, FAMACHA and fortnightly creates weights (until weaning) was used to statistical analyzes, that wereregression of these characteristics measured in mothers and creates development. It was concluded that older goatstend to calve early in the calving season and young goats tend to present better weight gain.(AU)
