Practices and Perceptions of Animal Contact and Associated Health Outcomes in Pregnant Women and New Mothers
out of 5 stars
| Contributor(s):: Hsin-Yi Weng, Kimberly Ankrom
Companion animals play an important role in our society. However, pregnant women and new mothers might have specific concerns about animal-associated health outcomes because of their altered immune function and posture as well as their newborn babies. The study was conducted to collect baseline...
Dog breed differences in visual communication with humans
| Contributor(s):: Konno, A., Romero, T., Inoue-Murayama, M., Saito, A., Hasegawa, T.
Domestic dogs (Canis familiaris) have developed a close relationship with humans through the process of domestication. In human-dog interactions, eye contact is a key element of relationship initiation and maintenance. Previous studies have suggested that canine ability to produce human-directed...
Positive and negative gestational handling influences placental traits and mother-offspring behavior in dairy goats
| Contributor(s):: Baxter, E. M., Mulligan, J., Hall, S. A., Donbavand, J. E., Palme, R., Aldujaili, E., Zanella, A. J., Dwyer, C. M.
Dairy animals are subjected to a number of potential stressors throughout their lives, including daily interactions with humans. The quality of these interactions may have direct consequences for the animal undergoing the experience, but if such events occur during gestation it may also affect...
Evaluation of the sexual behavior and testosterone concentrations of Mangalarga Marchador stallions
| Contributor(s):: Rua, M. A. S., Quirino, C. R., Bastos, R., Bartholazzi Junior, A., Santoro, P. N., Ribeiro, M. da S., Matos, L. F., Barreto, M. A. P.
Assessing the sexual behavior of stallions is extremely important because sexual behavior is linked to reproductive efficiency. The objective of this study was to evaluate the sexual behavior, testosterone concentration and libido of Mangalarga Marchador stallions from northern Rio de Janeiro...
How to train a dog to detect cows in heat-training and success
| Contributor(s):: Johnen, D., Heuwieser, W., Fischer-Tenhagen, C.
Efficient and accurate estrus detection is a key management factor determining acceptable reproductive performance in dairy herds. Previous studies have shown that dogs can differentiate between vaginal mucus samples of cows in estrus and vaginal mucus samples of cows in diestrus with an accuracy...
Mate choice, maternal investment and implications for ostrich welfare in a farming environment
| Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.
At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...
Behaviour of pre-pubertal gilts and its relationship to farrowing behaviour in conventional farrowing crates and loose-housed pens
| Contributor(s):: Ison, S. H., Wood, C. M., Baxter, E. M.
Individual variation in the reproductive performance of sows has the potential for greater negative impacts in loose-farrowing systems. Therefore, the ability to select gilts that will perform well would be a major advantage. This study investigated the behaviour of gilts during pre-pubertal...
Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink
| Contributor(s):: Malmkvist, J., Palme, R.
Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...
Effects of stage of gestation at mixing on aggression, injuries and stress in sows
| Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.
Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...
The potential of Social Network Analysis as a tool for the management of zoo animals
| Contributor(s):: Rose, P. E., Croft, D. P.
Social Network Analysis (SNA) enables the fine scale of animal sociality and population structure to be quantified. SNA is widely applied to questions relating to behavioural ecology but has seen little use in the application to zoo animal management, despite its clear potential. Investment in...
Potential welfare impacts of kill-trapping European moles ( Talpa europaea) using scissor traps and duffus traps: a post mortem examination study
| Contributor(s):: Baker, S. E., Shaw, R. F., Atkinson, R. P. D., West, P., Macdonald, D. W.
Moles are widely trapped as pests on farms and amenity land in Britain. Spring traps for killing mammals generally require welfare approval in the UK, but mole traps are exempt. Previous research demonstrated wide variation in the mechanical performance of mole traps. In this context, we aimed to...

Impact of zoo visitors on the fecal cortisol levels and behavior of an endangered species: Indian blackbuck ( Antelope cervicapra L.)
| Contributor(s):: Thangavel, Rajagopal, Govindaraju, Archunan, Mahadevan, Sekar
This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density)....
Socialization of a single hand-reared tiger cub
| Contributor(s):: Kelling, A. S., Bashaw, M. J., Bloomsmith, M. A., Maple, T. L.
Given the drawbacks of hand-rearing nonhuman animals in captivity, the practice is generally avoided, but it is sometimes necessary. A few scientific publications are available to guide managers toward best practices in hand-rearing, but the majority of articles focus on hand-rearing captive...
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...
