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 increase along the day in all treatments, while ?eating hay? increased along the day within Group T1, but decreased within Groups T2 and T3. It is concluded that the management conditions associated with the systems that were studied produced different behavioural patterns in the steers. Grazing behaviour is important for the animals, and the permanent or restricted possibility to perform it, determined by the production system, meant that the patterns of other behaviours changed to give priority to pasture intake.

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. |
