ALONZO, Lisandro Muñoz; GONZALEZ, Víctor Torres  e  LUENGO, Mario Briones. Prevalence of Crib-Biting and Weaving in Stabled Horses Tie Stalls. Rev. Med. Vet. [online]. 2018, n.37, pp.65-72. ISSN 0122-9354.  https://doi.org/10.19052/mv.vol1.iss37.8.

The objectives of this study were to evaluate the prevalence of crib-biting and weaving in horses stabled in tie stalls and to investigate the relationship between gender, age, and stereotypies. One hundred and seventy-seven half-bred saddle horse residents of a riding school, of both genders and between the ages of 3 and 20, distributed in three buildings with the same management conditions, were observed. For the statistical analysis according to gender, the horses were classified into 2 groups: geldings (n = 110) and mares (n = 67). According to age, the horses were classified into 2 groups: namely, 3 to 7 years old (n = 31) and 8 to 20 years old (n = 146). During three consecutive days, a single evaluator spent one day per building observing the presence or absence of crib-biting and weaving. Each given day was divided into 2 periods of observation: from 7:30 to 13:00 and from 14:30 to 20:00. Stereotypies were observed in 4.5% of the horses, i.e., 3.4% of the horses showed crib-biting and 1.1% showed weaving. We did not find horses showing crib-biting and weaving at the same time. No association was found between the prevalence of stereotypies and either gender or age of the horses. Our results suggest that visual and tactile contact with other horses, which occurs in tie-stall housing, could reduce the risk of developing weaving in tie-stall horses but not crib-biting.
