Good calf health is crucial for a successfully operating farm business and animal welfare on dairy farms. To evaluate calf health on farms and to identify potential problem areas, benchmarking tools can be used by farmers, herd managers, veterinarians, and other advisory persons in the field. However, for calves, benchmarking tools are not yet widely established in practice. This study provides hands-on application for on-farm benchmarking of calf health. At herd level, omphalitis O, median

We extend the concept of accessibility in temporal networks to model infections with a finite infectious period such as the susceptible-infected-recovered SIR model. This approach is entirely based on elementary matrix operations and unifies the disease and network dynamics within one algebraic framework. We demonstrate the potential of this formalism for three examples of networks with high temporal resolution: networks of social contacts, sexual contacts, and livestock-trade. Our investigations provide a new methodological framework that can be used, for instance, to estimate the epidemic threshold, a quantity that determines disease parameters, for which a large-scale outbreak can be expected.

Competing interests: The authors have declared that no competing interests exist. Networks are one of the most important ways to represent a finite set of elements with complex interaction patterns. As vast amount of data becomes publicly available, the analysis of complex networks plays an ever increasing role throughout different areas such as computer science, physics, social science and biology. Well known applications are the analysis of the World Wide Web [ 1 ], scientific collaborations [ 2 ] and protein interaction networks [ 3 ] to name only a few. It has become important to not only analyse network structures using graph theoretical tools, but to conduct numerical experiments [ 4 , 5 ]. This approach has led to numerous advances in epidemiological modelling, because it allowed to analyse the impact of the topology on the dynamics of infections [ 6 , 7 ].

As a first example, we consider a social contact graph [ 26 ] that has been recorded during a three-days conference. There is no additional mortality during transmissions. Table 8E. Therefore, herd size should be taken into account when including disease prevalence in on-farm benchmarking. Respiratory disease also shows a minor tendency for an increased frequency of occurrence, and multimorbidity results from a combination of all disorders. Genetic parameters of calf morbidity and stayability for US organic Holstein calves. Abstract We extend the concept of accessibility in temporal networks to model infections with a finite infectious period such as the susceptible-infected-recovered SIR model. Table 3 Number of pigs traded between every two classes of farms. In this case, farms or even traders move a small number of animals immediately, since they always find a slaughter house. J R Soc Interface. Detection of an outbreak as accurately and early as possible when it has not yet been widely spread is thus very important.

As an example using pig trade data, we computed the mortality rate in the approximately days long fattening period m F as:. Received Aug 29; Accepted Nov 8. In addition, umbilical disorders should find more consideration in future research. Calves born in the fall had a 1. Svensson C, Liberg P. Calf management risk factors on dairy farms associated with male calf mortality on veal farms. Thus, we have been able to deal with the disease dynamics and the temporal network in one unifying framework, taking into account both temporal and topological correlations. Moreover, on larger farms, it is more established to use prophylactic measures such as a vaccination against RD compared with smaller farms I General aspects of disease prevention. The added variability due to a low number of observations is a major problem when comparing farm level prevalence on small farms with reference data.
