Contenido :  ABSTRACT. The objective of the present study was to characterise the behaviour of Holstein steers in three different production systems. Forty-eight castrated Holstein males were randomly divided into three groups and allocated to the following three outdoor treatments: (T1) animals confined in a yard with an area of 210 m2, (T2) animals confined in a similar-sized yard but with 6 h of access to a pasture plot, (T3) animals maintained throughout the experiment on a pasture plot. Behaviour was recorded by scan sampling, 12 h a day (from 0700 hours to 1900 hours), 3 days per week, for 4 weeks evenly distributed from Week 7 to Week 16 of the experiment. So as to assess their patterns of behaviour, a negative binomial regression, correspondence analysis and logistic regressions were performed. Grazing was the predominant behaviour among Groups T2 and T3, while ?eating hay? was the most frequent behaviour among Group T1. For all treatments, lying was the second-most frequent behaviour. Despite animals in T2 having access to pasture for only half of the time with respect to those in T3, there was no difference between both treatments in the time spent grazing. Correspondence analysis of behaviour as a function of weather conditions showed that several behaviours were close to certain weather conditions, e.g. ?standing? and ?ruminating while standing? were closer to light rainy weather, while ?lying? or ?ruminating while lying? were more related to sunny weather.?Lying? tended to ... Presentar Todo

Contenido :  Abstract. Aim: To analyze group A rotavirus (RVA) environmental contamination in waters used for calves? consumption and to assess viral viability in dairy farm water sources. Methods and Results: We analyzed 202 samples of water used for calves? consumption and RVA was detected by RT-qPCR in 35.1% (95%CI: 28.9?42.0%). A marked pattern of seasonality was observed with higher frequency of detection in colder than warmer months (p=0.002). There was no association between viral load and season or between the number of milking cows in the herd and the detection of RVA in the farm. The viability of the RVA particles detected was confirmed by isolation of RVA in cell culture from 5/10 water samples. Furthermore, an RVA waterborne outbreak of neonatal calf diarrhea was described. Conclusions: We demonstrate that RVA is frequent in dairy farm waters, and that the virus is infectious and capable of generating a diarrhea outbreak. Significance and Impact of Study: Neonatal diarrhea syndrome leads to economic losses to the livestock industry worldwide. To determine transmission routes is essential to take action in this regard and reduce the impact that this syndrome has for the livestock production. The results obtained in this work alerts the dairy industry and highlights that mitigation strategies are crucial to improve the microbiological quality of this water.
