  1. Use of social network analysis to improve the understanding of social behaviour in dairy cattle and its impact on disease transmission

    Contributor(s):: de Freslon, Inès, Martínez-López, Beatriz, Belkhiria, Jaber, Strappini, Ana, Monti, Gustavo

    A better comprehension of cattle contact structure can enhance the prevention of the transmission of infectious agents within livestock farms. Social network analysis has proven to provide a more accurate picture of social structures than traditional methods. In this study, we focused on...

  2. Sexual behaviour in sheep is driven by body condition and the related nutritional and metabolic status

    Contributor(s):: Alhamada, Moutaz, Debus, Nathalie, González-García, Eliel, Bocquier, François

    To evaluate the effects of nutrition on the sexual behaviour of ewes, forty-eight mature (7.6±1.9years old) Merino d’Arles ewes with an average initial body condition score (BCS=2.26±0.23) and similar body weight (BW=46.6±3.8kg) were fed three contrasting diets for three months. The diets...

  3. Fos expression in the olfactory pathway of high- and low-sexually performing rams exposed to urine from estrous or ovariectomized ewes

    Contributor(s):: Mirto, Amanda Jo, Austin, Kathleen Jeanette, Uthlaut, Valerie Ann, Roselli, Charles Eugene, Alexander, Brenda Mae

    Exposure to estrous ewe urine stimulates investigation and mounting activity in sexually active but not sexually inactive rams. It was hypothesized sexual indifference may result from an inability to detect olfactory cues or an interruption of the pathway from detection of the olfactory stimulus...

  4. Is mare sexual behavior affected by age and can it predict ovulation?

    Contributor(s):: Rocha, Cláudia Emanuela, de Carvalho, Enilma da Cunha, de Castro, Flávia Carla Goulart Soares, Xavier, Ivis Luiz Gomes de Sena, Young, Robert John, Palhares, Maristela Silveira, da Silva Filho, José Monteiro, Carvalho, Renata Rezende, Vasconcellos, Angélica da Silva, Valle, Guilherme Ribeiro

    Although discontinued with the introduction of ultrasonography, the study of mare sexual behavior may provide useful information for herds that lack technical assistance. In order to investigate how mare sexual behavior is associated with ovulation and age, sexual behaviors were recorded for...

  5. Evaluating animal-assisted therapy in group treatment for child sexual abuse

    Contributor(s):: Dietz, Tracy J., Davis, Diana, Pennings, Jacquelyn

  6. Training rams to court and mate female goats

    Contributor(s):: Orihuela, Agustín, Ungerfeld, Rodolfo

    As Saint-Croix rams (sheep) exhibit low seasonal reproductive changes, they could be effective in inducing a reproductive response during the non-breeding season in anestrous does (goats) of breeds whose bucks show low reproductive activity. Three management practices for training rams to court...

  7. Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs

    Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.

    Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...

  8. #SaveBenjy: sexuality, queer animals, and Ireland

    Contributor(s):: McLoughlin, E.

    This paper explores the #SaveBenjy Crowdfunder campaign to save a Charolais bull in the Republic of Ireland who expressed sexual interest only in weanling bulls and not the heifers he was expected to impregnate. The prominence and popularity of #SaveBenjy is anything but coincidental. In May...

    Contributor(s):: McKay, S. A., Farnworth, M. J., Waran, N. K.

    This study distributed a questionnaire to cat or dog caregivers (owners) throughout Auckland, New Zealand, to investigate the attitudes of human companions toward the sterilization of their cats and dogs and the degree to which this occurs relative to demographic information gathered. A total of...

  11. Some preliminary evidence of the social facilitation of mounting behavior in a juvenile bull Asian elephant ( Elephas maximus )

    Contributor(s):: Rees, P. A.

    This study recorded sexual behaviour within a captive herd of 8 Asian elephants in England, UK, for approximately 230 h on 50 days over a period of 10 months (January-November 1999). A single adult and a single juvenile bull mounting cows more than 160 times were observed. When the juvenile bull...

  12. Extensive human presence at an early age of ostriches improves the docility of birds at a later stage of life

    Contributor(s):: Bonato, M., Malecki, I. A., Wang, M. D., Cloete, S. W. P.

  13. Immunocastration with Improvac TM reduces aggressive and sexual behaviours in male pigs

  15. Estrous and related behaviour in postpartum Holstein cows

    Contributor(s):: Hurnik, J. F., King, G. J., Robertson, H. A.

    Over a period of 1 yr, 3 consecutive groups, each consisting of 12 postpartum Holstein-Friesian cows aged from 3 to 9 yr, were observed continually for 80 days. The distribution of mounting behaviour showed evidence of circadian rhythm with the highest frequency occurring during the nocturnal...

  17. Effect of the presence of a dominant bull on performance of two age group bulls in libido tests

    Contributor(s):: Lopez, H., Orihuela, A., Silva, E.

    In 2 trials, twelve 15-month-old and ten 27-month-old sexually naive Simmental bulls were libido tested in the presence or absence of a dominant mature bull. In the 1st trial, individual sexual performance tests were conducted. On alternate tests days, a mature bull was present in an adjacent pen...

  18. Sexual performance of twin ram lambs and the effect of number and sex of contemporary siblings

    Contributor(s):: Price, E. O., Bench, C. J., Borgwardt, R. E., Dally, M. R.

    The objectives of this investigation were to determine the degree of correspondence in the sexual performance of twin male sheep and to compare the sexual performance of ram lambs born co-twin to another male (M-M), co-twin to a female (M-F) and as single (S) offspring. Individual ram lambs (n =...

  19. Effect of early fenceline exposure to estrous ewes on the sexual performance of yearling rams

    Contributor(s):: Price, E. O., Borgwardt, R., Dally, M. R.

    A total of 104 rams, 7-8 months of age, were given either no contact (NC), direct contact (DC) or fenceline (FL) exposure to oestrous ewes during a 3-week period in the autumn breeding season. When initially tested for sexual performance at 18-19 months, a higher proportion of NC rams exhibited...
