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 Abnormal weight bearing AWB was rarely detected median, 0. Calves with symptoms of more than one disorder at the same time multimorbidity, M were observed with a prevalence of 2.

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 ].

Recently, an analytical approach has been proposed to calculate the corresponding accessibility matrix, which was termed unfolding accessibility [ 13 , 20 ]. The effect of calfhood diseases on growth of female dairy calves during the first 3 months of life in New York state. These movements are extremely risky that can lead to the introduction of exotic animal diseases or zoonotic human pathogens like monkeypox in the United States in , which infected humans as well Then, we do not account for recovered nodes and thus all operations including the matrix R can be ignored. How benchmarking promotes farmer and veterinarian cooperation to improve calf welfare. Each calf was identified by the last five digits of its ear tag. It is likely that the higher number of calvings on large dairy farms increase the infection pressure, reduce the time spent on navel disinfection in individual calves or increase the occurrence of navel sucking in larger groups of calves of the same age In a Chilian study, a median herd level prevalence of Tracking All Initial Conditions: Matrix Formalism It is often important to evaluate the role of single nodes in a contact network with respect to their influence on the outbreak dynamics.

Cryptosporidium and Giardia in different age groups of Danish cattle and pigs—occurrence and management associated risk factors. Acta Vet Scand. Predicting epidemic risk from past temporal contact data. A new status index derived from sociometric analysis. Prevalence of four enteropathogens in the faeces of young diarrhoeic dairy calves in Switzerland. The majority of farms fed the calves twice daily The data spans the period from September to October and given the context of this dataset, allows to study the dynamics of sexually transmitted disease. To demonstrate the power of our approach, we will analyse disease dynamics on different empirical networks: networks of social contacts, sexual contacts, and livestock-trade.

Physica A. The diagnosis of O cannot be made on the basis of visual observation alone but requires the collection of vital parameters and palpation of the umbilical region of the calf. With our model, we will hereby focus on the number of potential transmission paths. The proportion of calves on dairy farms affected by the disorders addressed in the present study increased with herd size. One possible reason for this disparity is that time plays an important role in the computing of temporal measures like SDTC.
