Long-term stability of Avoidance Distance tests for on-farm assessment of dairy cow relationship to humans in alpine traditional husbandry systems / M. Battini, E. Andreoli, S. Barbieri, S. Mattiello. - In: APPLIED ANIMAL BEHAVIOUR SCIENCE. - ISSN 0168-1591. - 135:4(2011 Dec 31), pp. 267-270.
Abstract:
The present study investigates the long-term stability of two behaviour tests used to evaluate the human–animal relationship as well as gather information to refine on-farm welfare assessment protocols in alpine husbandry systems. Two tests, Avoidance Distance (AD) and Avoidance Distance at the Feeding rack (ADF) were performed on 50 lactating cows, bred in a loose housing system, following a protocol validated for dairy cows in the Welfare Quality® project. AD was performed on each animal at three different times: at the end of the indoor housing period just before the grazing period (AD bg); during the outdoor summer
grazing period in mountain ranges (AD dg); and at the beginning of the indoor housing
period, just after the grazing period (AD ag). ADF was performed on the same cows only
during the housing period, at the bottom of the valley, before (ADF bg) and after (ADF ag) the grazing period. Values of AD ag (113.93 ± 21.21 cm) were significantly higher (P < 0.05) than those observed in AD bg (71.07 ± 14.63 cm) and in AD dg (77.68
± 18.11 cm). No statistical significance was pointed out between AD bg and AD dg. A similar trend was recorded also for ADF, which was significantly higher after the grazing period (ADF bg vs ADF ag: 25.00
± 6.80 vs 47.50 ± 8.72 cm; P < 0.05). The summer grazing period seems to affect the
reaction of cows towards humans, and AD and ADF are not consistent throughout the year.
Certification of on-farm welfare in alpine husbandry systems, therefore requires performing these tests at the end of the indoor period, to gain better insight of the human–animal relationship for the environment in which cows live most of the year.
