  1. Androstenone induces horses to be more compliant with human-horse interactions

    Contributor(s):: Choi, Yeonju, Yoon, MinJung

    Olfactory signals play an essential role in communication in animals. Pheromones are volatile or nonvolatile chemicals that trigger social responses among animals. Therefore, pheromone treatment could, in theory, be used to modify horse behavior to improve human-horse relationships. Androstenone...

  2. Survey of Veterinarians Using a Novel Physical Compression Squeeze Procedure in the Management of Neonatal Maladjustment Syndrome in Foals

    Contributor(s):: Monica Aleman, Kalie M. Weich, John E. Madigan

    Horses are a precocious species that must accomplish several milestones that are critical to survival in the immediate post-birth period for their survival. One essential milestone is the successful transition from the intrauterine unconsciousness to an extrauterine state of consciousness or...

  3. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    | Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

  4. Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter

    | Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.

    There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...

  5. Environmental enrichment exerts anxiolytic effects in the Indian field mouse (Mus booduga)

    | Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.

    Environmental enrichment (EE) is known to have behavioral and physiological anxiolytic effects in several animal models. However, it is as yet unclear how EE modulates behavior of wild animals and the underlying molecular mechanisms. The adult male field mouse Mus...

  6. Salivary cortisol in captive dolphins (Tursiops truncatus): a non-invasive technique

    | Contributor(s):: Pedernera-Romano, C., Valdez, R. A., Singh, S., Chiappa, X., Romano, M. C., Galindo, F.

  7. A note on the effects of calf stimuli on the response of Zebu cows to Synchro-mate-B

    | Contributor(s):: Quesada, Y., Estrada, S., Cubero, M., Garcia, F., Galina, C. S., Molina, R., Orihuela, A.

    The effect of Synchro-mate-B (SMB, ear implant containing 6 mg norgestomet) was measured on the oestrous response and the establishment of cyclicity using different calf stimuli. Multiparous Zebu cows, were divided in three groups. In the first, 32 animals were treated with SMB leaving the calves...

  8. Hormonal influences on conditioned fear in pigs

    | Contributor(s):: Dantzer, R., Mormede, P.

  9. Sexual behaviour after treatment with prostaglandin-F<sub>2 alpha </sub>; in boars with suppressed concentrations of gonadal steroids

    | Contributor(s):: Estienne, M. J., Harper, A. F., Knight, J. W., Barb, C. R., Rampacek, G. B.

    We tested the hypothesis that prostaglandin-F2 alpha (PGF2 alpha ) enhances sexual behaviour in boars with suppressed testosterone and estradiol secretion. After semen collection at week 0, boars received an s.c. implant containing a gonadotropin-releasing hormone agonist (GnRHa) or were...
