Infection by Mycoplasma agalactiae in dairy goat herds in the microregions of Cariri in Paraíba State, Brazil / Infecção por Mycoplasma agalactiae em rebanhos caprinos leiteiros nas microrregiões do Cariri na Paraíba

O objetivo deste trabalho foi verificar a ocorrência de Mycoplasma agalactiae, com o uso da reação em cadeia da polimerase (PCR), em 30 rebanhos caprinos leiteiros nas microrregiões do Cariri Ocidental e Oriental do estado da Paraíba. Das 120 amostras de leite testadas, nove (7,5 por cento) apresentaram amplificação de apenas um fragmento com 360pb. As amostras que amplificaram este fragmento estavam presentes em 6/30 (20 por cento) fazendas localizadas nos municípios de Amparo, Santo André e Gurjão.

Avaliação de uma metodologia profilática contra a mastite clínica em ovelhas da raça Santa Inês / Evaluation of a prophylactic method against clinical mastitis in Santa Inês ewes

Mastitis is an important problem for the Santa Inês ewes and is a disease strongly related to the management carried out in the herd. A comparative study was carried out between the proposed method based on drying (treatment) and the traditional method (control). Sixty-two Santa Inês ewes raised in a semi-extensive system were divided in two groups of 31 ewes each: treatment group (G1) and control group (G2). The animals were monitored each week searching for clinical sings of mastitis. In 8.4 percent of G1 and 41.3 percent of G2 animals, the udder was warm and hyperemic. The presence of residual milk was lower in G1 (24.3 percent) compared to those of G2 (74.2 percent). The proposed treatment for the control of ovine mastitis significantly reduced the frequency of the clinical signs of the disease.

Perfil sanitário e zootécnico de rebanhos caprinos nas microrregiões do Cariri paraibano / Sanitary profile of goat flocks in Cariri micro regions, Paraiba State, Brazil

This work was performed in 60 goat farms located in 15 counties of the micro regions of Western and Eastern Cariri, in Paraiba, to describe and analyze the sanitary profile of the flocks. Visits were done and the answers, obtained from questionnaires that were applied to the farmers, were used. It was observed a mortality of 20 percent in young animals in 80 percent of the farms. The presence of technical assistance in 93.3 percent in the studied farms, adoption of prophylactic calendar in 85 percent and parasitic control in 83.3 percent of the flocks were also observed
