We collected 50 samples of curasow feces from the Scientific and Cultural Breeding Center in the city of Poços de Caldas. The samples were enriched in broth medium Tetrationato and Cystine-selenite and plated on Salmonella Shigella (SS), Mac Conkey (MC), endo-C (EC), Brilliant Green (VB) and Eosyn Methilen Blue EMB, remaining at 37 °C for 24h. Colonies suspected of Salmonella were inoculated in tubes containing Agar Triple Sugar Iron (TSI) and again incubated at 37 ºC for 24h. Tubes with characteristic growth were submitted to slide agglutination test with polyvalent somatic and flagellar serum. The medium SS, MC and VB were the most efficient for growing, and 36% of samples were positive for Salmonella spp. As birds are important reservoirs of Salmonella spp and it may represent a high risk to human health, there is a need to implement a cleaning routine in enclosures avoiding contamination between the enclosures and the consequent entrainment of these micro-organisms, by the keepers until their homes or other venues. The presence of Salmonella in breeding centers may be responsible for lower hatchability of eggs, undermining the purpose of the entity, which is to study and maintain the various birds species.

The aim of this research was to evaluate, by preference tests, the ability of perception of broiler chicks in the recognition of objects and foods of different colors. The survey was conducted in Brazil and consisted in the conditioning of 60 sexed one-day-old chicks using 30 male chicks and 30 female chicks for three days with blue balls and red food colors chosen for having opposed chromaticities. After the conditioning phase, a preference test was performed, in which the animals were placed individually in the center of an arena test with four options: red food, blue food, red balls and blue balls. Each bird was measured for 10 minutes. Latency to the first peck and the number of pecks, the number of sequential pecks at each object type or food, the total time the bird in each occupied compartment and the first occupied slot were recorded. According to the results, female chicks are less inhibited when in contact with a new situation when compared with males. However, males were able to establish a standard environment in the conditioning phase and opted for the compartment which was closer to that situation, associating the blue color to the ball and red color to the food. Overall, among the types of object colors and between types of food colors, the birds took less time for the decision on the choice of blue food and blue ball, showing a greater attraction, at first, to this color. Between the two ball colors, shorter latency period, greater number of interactions as well as more time spent on site were related to the blue sphere, verifying greater preference for this object. When evaluating the types of food colors, it was observed that the highest averages related to the number of pecks, and sequential pecks occurred with red food. Therefore, it is concluded that the birds recognized the red and blue food object, with the blue color having greater attractiveness for broiler chicks when compared to red.

Objetivou-se com este trabalho avaliar a ponta XR na deposição da calda de pulverização com diferentes combinações de plantas de feijão, Brachiaria plantaginea e Bidens pilosa, em dois volumes de aplicação, com e sem a adição de surfatante Silwet. Foi utilizado como traçador o corante Azul Brilhante FDC -1 na concentração de 500 ppm para quantificar a deposição. Os tratamentos constituíram-se de sete combinações de plantas: (feijão), (B. plantaginea), (B. pilosa), (feijão + B. plantaginea), (feijão + B. pilosa), (B. plantaginea + B. pilosa) e (feijão + B. plantaginea + B. pilosa). O delineamento experimental foi o inteiramente casualizado. Foram avaliadas as pontas de jato plano XR 110015 VS e XR 11002 VS com volumes de aplicação de 150 e 200 L ha-1, respectivamente, com e sem a presença do Silwet a 0,05% v v-1. Após a aplicação, as plantas foram imediatamente coletadas e, em seguida, lavadas em 100 mL de água destilada, para posterior quantificação do traçador em espectrofotômetro. As pontas XR apresentaram comportamento distinto na deposição das gotas de pulverização nas espécies estudadas; a adição de um surfatante à calda de pulverização aumentou a uniformidade da deposição nos alvos e contribuiu para a redução do volume de aplicação.
