Video monitoring of daily routines in a farm has enabled us to collect a sizable amount of data. By measuring the time lapse between the passage of consecutive animals, some features of the flow regime can be assessed. A quantitative definition of clogging is demonstrated based on the passage time statistics. These display broad tails, which can be fitted by power laws with a relatively large exponent. On the other hand, the distribution of burst sizes robustly evidences exponential behavior. Finally, borrowing concepts from granular physics and statistical mechanics, we evaluate the effect of increasing the door size and the performance of an obstacle placed in front of it. The success of these techniques opens new possibilities regarding their eventual extension to the management of human crowds. 000044959 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-26675 000044959 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000044959 590__ $$a2.252$$b2015 000044959 591__ $$aPHYSICS, MATHEMATICAL$$b6 / 53 = 0.113$$c2015$$dQ1$$eT1 000044959 591__ $$aPHYSICS, FLUIDS & PLASMAS$$b10 / 30 = 0.333$$c2015$$dQ2$$eT2 000044959 592__ $$a1.183$$b2015 000044959 593__ $$aCondensed Matter Physics$$c2015$$dQ1 000044959 593__ $$aStatistical and Nonlinear Physics$$c2015$$dQ1 000044959 593__ $$aStatistics and Probability$$c2015$$dQ2 000044959 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000044959 700__ $$aPastor, J.M. 000044959 700__ $$0(orcid)0000-0003-0042-8800$$aFerrer, L.M.$$uUniversidad de Zaragoza 000044959 700__ $$0(orcid)0000-0002-2724-2785$$aRamos, J.J.$$uUniversidad de Zaragoza 000044959 700__ $$aMartín-Gómez, C. 000044959 700__ $$aZuriguel, I. 000044959 7102_ $$11009$$2617$$aUniversidad de Zaragoza$$bDpto.
