Capacitação de produtores rurais para a melhoria da qualidade do leite cru produzido na região de Araçatuba - SP

This paper reports the results of an extension project carried out at Unesp/Veterinary Medicine course in Araçatuba city with milk farmers of the region. The aim of the project was to supply information to farmers concerning to good quality milk production and, at the same time, to follow up the evolution of milk quality parameters, according to the current Brazilian legislation. Every 45 days, approximately, lectures were presented to milk farmers in Araçatuba city region, approaching chemical and microbiological composition of milk, prevention and detection of mastitis, hygiene proceedings in milking and conservation of milk, cleaning and sanitization operations of facilities and equipments and prevention of adulteration. During the intervals between lectures, milk samples were collected from collective milk cooling tanks and analyzed for microbiological, hygienic and physicochemical tests. The main inadequacies in milk quality were high total bacteria and somatic cells counts, low solids contents and water addition. These problems did not proceed to betterment during the project time. So, it was concluded that the time for instruction of farmers was not enough for a progress in the quality of the milk produced in the region, pointing out the need in continuing this kind of work.

Diagnóstico de situação das práticas de manejo sanitário em sistemas de produção de bovinos de corte

We interviewed 21 farmers in order to access which sanitary practices adopted in the production systems of beef cattle on farms located in São Paulo, Mato Grosso, Mato Grosso do Sul and Rondonia. The survey was conducted through a qualitative approach to the collection of data obtained through questionnaire and personal interview with the landowners. We questioned the attitudes and sanitation procedures in these current production systems such as veterinary assistance, preventive health practices and disease surveillance, knowledge of health hazards for the safe production of food, animal feed, vaccine and immunizations, registration system, measures with newborns, products used in the environment and animals, grace period, employee training, destination of the dead animals, among others. Along with the data found that only 30% of properties had veterinary care, 67% said they meet the expiration dates of the products, although it was not mentioned on the products if there were any. In only 48% of properties were veterinarians who prescribed drugs to animals. Only two of the owners confirmed buying and using expired products in animals and only 48% have received some training on the property. In this setting, it is evident that farmers should be better prepared for insertion of its products in a highly demanding and competitive market. In this context, add value to the product depends mainly on the condition of sanitation of the herds.

Valores hematológicos de morcegos hematófagos Desmodus rotundus (E. Geoffroy, 1810) mantidos em cativeiro

Hematological values from captive vampire bats Desmodus rotundus (E. Geoffroy, 1810). Desmodus rotundus is one of the hematophagous bat species that are responsible for significant losses to livestock and has important involvement on public health. The great interest on this bat species made it becomes the target of many investigations a required its maintenance in laboratories. Similarly to others mammals, hematological evaluation has been utilized to assess the health and morbidity state of bats, however there are scarce studies with captive bats. The aim of this study was to investigate the hypothesis that is possible to feed the vampire bat D. rotundus with frozen blood treated with citrate during a long captivity period without hematological dyscrasias. Therefore, complete blood count was performed monthly from 15 adult females kept for 345 days in cages and fed with frozen blood added to citrate. The erythrocyte concentration (9.02 ± 1.43 x1012/L), PCV (0.47 ± 0.08 L/L) and hemoglobin (163.9 ± 31.5 g/L) obtained from free-living bats (immediately after capture) were lower or similar to those obtained after 345 days of captivity, presenting erythrocytes’ count of 11.01 ± 0.82 x1012/L, packed cell volume of 0.50 ± 0.05 L/L and hemoglobin level of 158 ± 10.1 g/L. The total white blood cell (11.09 ± 6.07 x109 /L) and segmented neutrophil counts (9.85 ± 3.5 x109 /L) of free living D. rotundus decreased significantly after 345 days of captivity, with values of 3.98 ± 1.98 and 1.87 ± 978.6 x109 /L respectively, which are similar to bats from temperate regions in hibernation period. This study proved that is possible to feed D. rotundus for long periods of captivity with citrated blood without the occurrence of anemia, erythrocyte or other hematologic dyscrasia

Resistência do Rhipicephalus (Boophilus) microplus aos carrapaticidas: revisão de literatura

O carrapato Rhipicephalus (Boophilus) microplus é o principal ectoparasito de bovinos e esta associado à transmissão de doenças, causando grandes prejuízos econômicos a indústria da pecuária no geral. O surgimento de populações de carrapatos R.(B) microplus resistentes aos carrapaticidas comerciais é um problema observado em muitas propriedades rurais no mundo, gerando um prejuízo de aproximadamente US$ 7 bilhões por ano. O uso correto dos princípios ativos carrapaticidas existentes e conhecimento das diversas formas de resistência do R. (B) microplus a estes princípios são de grande valia para prevenir ou então diagnosticar precocemente o aparecimento da resistência nas diversas populações deste ectoparasita.

Monitoramento microbiológico da mastite ovina na região de Bauru - SP

Mastitis is an acute or a chronic inflammation of the udder, represented for physical, chemical and bacteriological milk alterations. It is notable that ovine milk represents high economic importance, and it can be used in the production of cheeses and other derivates, contributing for the farmer’s recipe enlargement. However, the mastitis in animals can determine the reduction of milk quantity and quality in infected animals. This may determine lambs’ weight loss and increase animal’s mortality. By the other hand, considering Public Health issues, mastitis can cause milk nutrients losses and promote the microorganisms’ multiplication that may lead to diarrheas and to other zoonosis in humans. This study aimed to evaluate 159 sheep mastitis status in 20 small farms located in Bauru (SP) region. Of the 309 colected samples, in 97 (31.4%) were isolated microorganisms of the genus Staphylococcus sp., which them 27.5% being coagulase negative Staphylococcus and 3.9% coagulase positive Staphylococcus. Of 177 isolates, 97 (54.8%) were represented by the genus Staphylococcus sp., which them 57 (58.8%) from pure culture and 40 (41.2%) in association. Most agents isolated were sensitive to antibiotics used in the test. Thus, we could verify the isolation of infectious microorganisms such as coagulase positive and negative Staphylococcus and, as well in dairy cattle, preventive measures to obtain hygienic milk are extremely important in order to get a final product with quality and safe in food and microbiological point of view.
