Role of noise and music as anxiety modulators: Relationship with ovarian hormones in the rat
Contributor(s):: Escribano, Begoña, Quero, Ismael, Feijóo, Montserrat, Tasset, Inmaculada, Montilla, Pedro, Túnez, Isaac
This work aims to verify the role of noise and music as anxiety modulators and their relationship with ovarian hormones. For this purpose, female Wistar rats were used and treated, forming different experimental groups, with 17-β-estradiol, progesterone, allopregnanolone, finasteride (inhibitor...

Maternal stress effects on offspring development have been studied largely in rodents and primates, and to a lesser extent in farm animals. Potential lack of knowledge concerning prenatal stress on farm animals is regrettable because they are frequently subjected to a variety of husbandry...
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...
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...
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...

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...

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...
Euthanasia methods, corticosterone and haematocrit levels in Xenopus laevis : evidence for differences in stress?
Contributor(s):: Archard, G. A., Goldsmith, A. R.
Amphibians, like other vertebrates, respond to acute stressors by releasing glucocorticoid steroid hormones that mediate physiological and behavioural responses to stress. Measurement of stress hormones provides a potential means to improve the welfare of laboratory animals. For example,...
