Reproductive behavior of Helmeted Guinea fowl ( Numida meleagris ): mating system and parental care
Contributor(s):: Elbin, S. B., Crowe, T. M., Graves, H. B.
Reproductive behaviour was studied in free-ranging domestic Helmeted Guinea fowl. The general pattern of mating behaviour was for [male][male] to first associate sequentially with one to several [female][female]. After 4-6 wk of short-term associations, 1 [male] and 1 [female] typically paired...
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...
Sexual behaviour and fertility in broiler breeder domestic fowl
Contributor(s):: Duncan, I. J. H., Hocking, P. M., Seawright, E.
The decreased fertility of breeding broiler fowls in the later part of the laying year was studied. Males were penned individually with 15 [female][female], and fed separately from them at various levels of energy, in order to attain different body weights, and at 2 levels of protein. The...

Contributor(s):: Chenoweth, P. J., Chase, C. C., Jr., Larsen, R. E., Thatcher, M. J. D., Bivens, J. F., Wilcox, C. J.
The sexual performance (libido score, number of services, time to first mount and time to sexual inactivity) of yearling Senepol, Romosinuano, American Angus, Hereford, Brahman and Nelore x Brahman bulls was assessed in January, April, July and October of 1991 (trial 1) and 1992 (trial 2) at the...
Cruelty to animals in normative, sexually abused, and outpatient psychiatric samples of 6- to 12-year-old children: relations to maltreatment and exposure to domestic violence
Contributor(s):: Ascione, F. R., Friedrich, W. N., Heath, J., Hayashi, K.
The associations between the reported cruelty to animals and touching of animal's sex parts by children and the reported presence of physical abuse, sexual abuse and domestic violence were examined in 3 groups of children. The maternal caregivers of 1433 children (6-12 years old) completed the...
An evaluation of the suitability of contraceptive methods in golden-headed lion tamarins ( Leontopithecus chrysomelas ), with emphasis on melengestrol acetate (MGA) implants: (II) endocrinological and behavioural effects
Contributor(s):: Vleeschouwer, K. de, Elsacker, L. van, Heistermann, M., Leus, K.
In order to be suitable, a contraceptive method should have little or no effects on social organization or behaviour. In callitrichids, changes in socio-sexual interactions between group members, due to hormonal changes induced by contraception, may have consequences for the reproductive...
Effects of fattening boars in mixed or single sex groups and split marketing on pig welfare
Contributor(s):: Boyle, L. A., Bjorklund, L.
Our aim was to evaluate the effects of single or mixed sex fattening of boars and split marketing (SM) on pig welfare. Female (n=10), male (n=10) and mixed sex (n=10) groups were fattened to 105 kg. Two focal pigs per pen were selected for continuous behaviour observations and skin lesion...
The behavioural repertoire of non-breeding group-housed female laboratory rabbits ( Oryctolagus cuniculus )
Contributor(s):: Held, S. D. E., Turner, R. J., Wootton, R. J.
Many studies on group-housing of laboratory rabbits to date have focused on management aspects and economic implications. Our aim here is to provide behavioural background information for future investigations focusing on behavioural and welfare aspects of group-housing. In the present study, we...
The effect of substrate availability on behavioural and physiological indicators of welfare in the African cichlid ( Oreochromis mossambicus )
Contributor(s):: Galhardo, L., Correia, J., Oliveira, R. F.
Male African cichlids (Oreochromis mossambicus) establish territories on the substrate upon which spawning pits are dug, thus attracting females. The substrate, therefore, plays a very significant role in its lifecycle. The effects of substrate access on behaviour and physiology in captivity were...

Sexual relations with animals (zoophilia): an unrecognized problem in animal welfare legislation
Contributor(s):: Bolliger, G., Goetschel, A. F.
Sexual contact with animals (zoophilia) has always been part of human culture, and is more widespread than generally thought. While it was severely penalized on ethical and religious grounds for centuries, the age of Enlightenment led to more rational views on this topic and, consequently, milder...
