  1. Effects of horn status on behaviour in fattening cattle in the field and during reactivity tests

    Contributor(s):: Reiche, Anna-Maria, Dohme-Meier, Frigga, Claudia Terlouw, E. M.

    Disbudding is in the short-term invasive and needs pharmacological pain treatment but it facilitates animal management. The present study investigates the longer-term consequences on behaviour to evaluate possible effects on animal welfare. Experiment 1 (E1) used 81 bulls up to the age of 12 and...

  2. Effects of restraint with or without blinds at the feed barrier on feeding and agonistic behaviour in horned and hornless goats

    Contributor(s):: Hillmann, Edna, Hilfiker, Sandra, Keil, Nina Maria

    The strict dominance hierarchy in goats bears the risk of low-ranking goats not getting adequate access to feed, especially for goats in small groups. The aim of our study was to test the effect of restraint in headlocks with and without blinds at the feed barrier on feeding and agonistic...

  3. The introduction of individual goats into small established groups has serious negative effects on the introduced goat but not on resident goats

    Contributor(s):: Patt, Antonia, Gygax, Lorenz, Wechsler, Beat, Hillmann, Edna, Palme, Rupert, Keil, Nina M.

    The introduction of an individual goat into an established group is likely to result in intense agonistic interactions, which may adversely affect the welfare of both the introduced goat and the resident goats. To assess this situation, we introduced eight horned and eight hornless goats one at a...

  4. The nature of the beast: curating animals and ancestors at Çatalhöyük

    Contributor(s):: Meskell, Lynn

  5. Using fecal hormonal and behavioral analyses to evaluate the introduction of two sable antelope at Lincoln Park Zoo

    Contributor(s):: Loeding, E., Thomas, J., Bernier, D., Santymire, R.

    Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The...

  6. Preliminary evaluation of the effectiveness of captive-bolt guns as a killing method without exsanguination for horned and unhorned sheep

    Contributor(s):: Gibson, T. J., Ridler, A. L., Lamb, C. R., Williams, A., Giles, S., Gregory, N. G.

  7. Loose housing of small goat groups: influence of visual cover and elevated levels on feeding, resting and agonistic behaviour

    Contributor(s):: Aschwanden, J., Gygax, L., Wechsler, B., Keil, N. M.

    Frequent social conflicts among goats due to their strict rank relationships can pose problems in loose housing of goats by negatively influencing feeding and resting times of low-ranking group members. In this study, we tested whether enrichment of loose-housing pens with structural elements...

  8. Social distances of goats at the feeding rack: influence of the quality of social bonds, rank differences, grouping age and presence of horns

    Contributor(s):: Aschwanden, J., Gygax, L., Wechsler, B., Keil, N. M.

    To minimize social conflicts between goats and improve pen design, knowledge of factors affecting social distances at the feeding rack is needed. In our study, we investigated the influence of the quality of social bonds, rank differences, grouping age and presence of horns on two types of social...

  9. Structural modifications at the feeding place: effects of partitions and platforms on feeding and social behaviour of goats

    Contributor(s):: Aschwanden, J., Gygax, L., Wechsler, B., Keil, N. M.

    In goat housing, agonistic interactions elicited by close distances at the feeding place can have a negative impact on feed access and performance of low-ranking group members. The aim of this study was to investigate experimentally how structural modifications at the feeding place affect the...

  10. A brief report on intraspecies aggressive biting in a goat herd

    | Contributor(s):: Tolu, C., Savas, T.

    This study aimed at analysing the effects of age, horn and places on biting and butting as intraspecies aggressive activities. Seventy-two Turkish Saanen goats were used as animal material and 22,686 aggressive behaviours were recorded in different places from a total of 118 h direct observation....

  11. A comparison of space requirements of horned and hornless goats at the feed barrier and in the lying area

    | Contributor(s):: Loretz, C., Wechsler, B., Hauser, R., Rusch, P.

    Loose housing of horned goats is more common than loose housing of horned cattle, and recommendations concerning the design of housing systems for horned goats are needed. In this study, we compared the behaviour of horned and hornless goats kept in deep litter pens to investigate their space...

  12. The significance of horns and other male secondary sexual characters in female bovids

    | Contributor(s):: Estes, R. D.

    A hypothesis is presented which states that [female][female] mimic [male] secondary sexual characters (e.g. through the evolution of horns) to buffer their [male] offspring against the aggression of dominant [male][male], thereby prolonging the presence of their sons in the natal herd and home...

  13. Interpreting the bucrania of Catalhoyuk: James Mellaart, Dorothy Cameron, and beyond

    | Contributor(s):: Relke, J.

    The bucranium (bull's head and horns) has been recognized as the most prevalent three-dimensional art form found during the excavations of the Neolithic village of Catalhoyuk in central Turkey. James Mellaart interpreted it as the symbol of the son and lover of the Great Mother Goddess,...

  14. Social behaviour and injuries of horned cows in loose housing systems

    | Contributor(s):: Menke, C., Waiblinger, S., Folsch, D. W., Wiepkema, P. R.

    The relationship between social behaviour and skin injuries (caused by horns) of loose housed horned cows was investigated on 35 dairy farms (mean herd-size, 34.54, range, 8-80). While the frequencies of 2 agonistic behaviour elements (push and chase away) were positively correlated with the...
