Qualidade Higiênico-Sanitária e Demanda de Cloro da Água de Dessedentação de Galinhas de Postura Coletadas em Bebedouros Tipo Nipple e Taça

O objetivo deste estudo foi avaliar a influência de dois tipos de bebedouros nipple e taça, utilizados na dessedentação de aves de postura e o incremento da demanda de cloro na água oferecida pelos dois tipos de bebedouros estudados. Foram realizadas as contagens de coliformes totais, coliformes fecais, Escherichia coli, estreptococos fecais e microrganismos mesófilos. Os resultados obtidos figuraram que as amostras de água dos reservatórios, de ambos os bebedouros, apresentaram-se contaminadas microbiologicamente antes de passarem pelos bebedouros. A contaminação por bactérias de poluição fecal foi maior nas amostras colhidas nos bebedouros tipo taça, assim como eles foram responsáveis por um maior acúmulo de matéria orgânica, tendo então uma elevada demanda de cloro e uma maior influência na depreciação da qualidade da água fornecida às aves. Dos dois tipos de bebedouros estudados, o tipo nipple mostrou ser o menos deletério no que concerne à qualidade da água entretanto, independente do tipo de bebedouro utilizado na dessedentação das aves, a desinfecção da água é um ato imprescindível à manutenção de sua qualidade e à eliminação de futuros patógenos.

Water intake behavior of broiler chickens exposed to heat stress and drinking from bell or and nipple drinkers

The aspects involved in broiler water intake are not well known, despite the importance of water in animal nutrition and physiology. Water intake behavior should be taken into account when deciding on different types of drinkers. Bell and nipple drinkers are the most commonly used in commercial broiler production. Broilers were housed in cages equipped with two different drinker types and raised at two different environmental temperatures (25 and 34 ºC) to evaluate water intake behavior and volume. Broiler water intake behavior was influenced by drinker type. Birds visited bell drinkers less often, but presented higher total water intake per visit to the drinker as compared to those drinking from nipple drinkers. The results of this study suggest that both broilers drinking behavior and water intake volume should be taken into account when deciding on drinker type to equip broiler houses.

Cytological result of in situ ductal carcinoma in nipple discharge: a rare diagnosis

Background: More than half of women present nipple discharge during reproductive age. Case: This case is about a 36 years old woman with unilateral spontaneous hyaline nipple discharge associated with breast pain. The study of scintimammography was compatible with multifocal proliferative lesion in situ. It was performed cytological smear of nipple discharge. It was paucicellular smear represented by cluster of ductal cells in three-dimensional design with hyperchromatic nuclei in the presence of myoepithelial cells. Red cells and signs of necrosis were not observed. The diagnosis of in situ ductal carcinoma was confirmed in biopsy and mastectomy specimen through the expression of calponin in myoepithelial cells at immunohistochemistry. It is known that the cytological examination of nipple discharge has low sensitivity and specificity. However, it is an easy and inexpensive procedure. Suspicious or positive results, may be important for guidance workup of patients in order to perform earlier diagnosis of malignancy. Conclusion: this case demonstrates that in situ ductal carcinoma can be characterized by positive nipple discharge, and cytology sample is an important tool for the diagnosis of suspicion of malignancy and further diagnostic investigation.

Influência da forma de administração e da quantidade fornecida de colostro sobre a concentração de proteína total e de suas frações eletroforéticas no soro sangüíneo de bezerros da raça Holandesa

This study was carried out to evaluate the effect of the amount of colostrum (two and four liters) and methods of colostrum feeding (direct suckling from the cow, feeding colostrum using nipple bottle, and no feeding colostrum) on different blood traits. Thirty two Holstein calves (four groups of eight animals each) were randomly allotted to four treatments: treatment 1 - calves were hand fed four liters of colostrum; treatment 2 - calves were hand fed two liters of colostrum; treatment 3 - calves were fed colostrum directly from the cow, and treatment 4 - calves were not fed colostrum. Higher values of total serum protein, betaglobulins and gamaglobulins were observed in the calves after 24 hours of colostrum feeding. No differences among animals fed colostrum directly from the cow and hand fed two or four liters of colostrum were observed for total protein and eletrophoretic fractions. However lower values of total and eletrophoretic fractions were observed for calves that were not fed colostrum.

Uso da fluorsceína na identificação dos vasos linfáticos superficiais das glândulas mamárias em cadelas

Uma técnica empregando fluoresceína sódica 5% e luz ultravioleta foi desenvolvida para a identificação dos trajetos dos vasos linfáticos superficiais das glândulas mamárias em dez cadelas. A fluoresceína foi injetada por via intradérmica ao redor da base de cada mamilo e cada mama foi observada após 5, 15, 30 e 60 minutos. em cada animal, primeiramente, foram avaliadas as mamas torácica cranial, abdominal cranial e inguinal das cadeias direita e esquerda e 48 horas após as mamas torácica caudal e abdominal caudal das cadeias direita e esquerda. de um total de 97 mamas injetadas, em 8 a fluoresceína não foi captada pelos linfáticos. O tempo de 30 minutos foi o mais adequado para a visualização total dos trajetos. Mostrou ser um método simples, rápido e inócuo de verificação in vivo de vasos linfáticos.

Avaliação de desempenho do microaspersor amanco em bancada de testes

The need for a rational use of water and supply of food for a growing world population have led to the development of research in the area of irrigation systems. Thus, some irrigation systems which join efficiency with low cost of material have been developed. Although some technical characteristics are provided by the manufacturers, tests are required to verify functioning of the system and uniformity of water distribution. Continuous research on uniformity, characteristics of the materials and design of water distribution systems is essential for system improvement. Therefore, the objective of this work was to evaluate the CV (manufacturer's coefficient of variation) of Amanco microsprinkler (1.0 mm light green nipple) using bench testing in the laboratory of Irrigation at UNESP - FCA campus of Botucatu-SP. Twenty-five microsprinklers in a sequential design were used in the tests. Three flow systems were tested as follows: a Coil system based on serial connected pipes; a Lateral system, the most common system in which secondary lines are fed by a main line; and a Mesh system used in the urban water supply. The results showed that 4.17% CVf met the production standards and the Lateral and Mesh systems were similar regarding outflow using bench testing. The Mesh system presented the highest mean value of outflow and the lowest range of variation.
