Livestock production has migrated to the Midwest region of Brazil; however, these regions are environmentally unsuitable for livestock specializing in milk production, due to high temperatures. This environment can be improved using inserting trees into the pastures. The objective was to evaluate the effects of adding grazing trees on the behavior of dairy heifers in the Midwest region of Brazil. Piatã grass was managed in: open pasture system, OPS (shade level 0%), the worst treatment for animal production since the solar radiation and temperature are deleterious to animal welfare; moderate shade system (shade level 20%), the supposed adequate system where the animals find shady areas, but there is light available for photosynthesis; and intensive shade system (shade level 70%), the worst treatment for vegetal production since the light is limited for grass growth. Shade was provided by Eucalyptus trees. Heifer behavior was evaluated from 08:30 to 16:00 over three periods. In the OPS, the heifers searched for cow drinkers and remained there for a long time, refreshing themselves by floating in water and muddy places. Heifers demonstrated a behavior of attempting to return to grazing activity under the OPS during the hottest time of the day, but without success. Ruminating activity was not affected by any factor. The shade level affected the distribution of time spent on an activity and the time of day at which each activity happened. The moderate shade level is enough to ensure stability in the daily behavior of dairy heifers.

Caseous lymphadenitis is an infectious sheep and goats disease caused by Corynebacterium pseudotuberculosis and characterized by abscesses in superficial and visceral lymph nodes. C. pseudotuberculosis strains isolated from these hosts have been shown to be very difficult to type by the existing methods. The aim of this study is evaluating the potential of the Enterobacterial Repetitive Intergenic Consensus (ERIC-PCR) as a tool for molecular typing of C. pseudotuberculosis strains isolated in sheep. One hundred and twenty seven isolates of C. pseudotuberculosis were isolated from lesions suspected to have had caseous lymphadenitis collected from sheep at the slaughterhouse. Animals were from 24 flocks in 13 municipalities of the Minas Gerais State, Brazil. Species identification of the isolates was performed by routine biochemical tests and mPCR. Fingerprint was performed by RAPD using ERIC-1R, ERIC-2 and ERIC-1R+ERIC-2 primers. Seventeen different genotypes were generated by ERIC 1-PCR, 21 genotypes by ERIC 2-PCR and 21 genotypes by ERIC 1+2-PCR. Hunter-Gaston Discrimination Index (HGDI) found for ERIC 1, ERIC 2, ERIC 1+2 PCR were 0.69, 0.87, and 0.84, respectively. For most herds evaluated observed at most three different genotypes among isolates from animals of these property, in all ERIC-PCR assays. However a few flocks observed between four and nine genotypes per flock. The W Kendall value found for correlation among the three techniques of ERIC-PCR was 0.91 (P<5.0 x 10(-6)). The results show that ERIC-PCR has good discriminatory power and advantages over other DNA-based typing methods, making it a useful tool to discriminate C. pseudotuberculosis isolates.
