Stereotypic behaviour predicts reproductive performance and litter sex ratio in giant pandas
Breeding and welfare problems confront many conservation breeding programs. Stereotypies—repetitive, unvarying, functionless behaviours —are common abnormal behaviours that often arise in suboptimal conditions. While the role of stereotypies in welfare assessment is well studied, few investigations address the relationship between stereotypic behaviour and reproduction. We examined the correlation between stereotypic behaviour and reproductive performance in […]
Effects of inbreeding on reproductive success, performance, litter size, and survival in captive red wolves (Canis rufus)
Abstract 10.1002/zoo.20262.abs Captive-breeding programs have been widely used in the conservation of imperiled species, but the effects of inbreeding, frequently expressed in traits related to fitness, are nearly unavoidable in small populations with few founders. Following its planned extirpation in the wild, the endangered red wolf (Canis rufus) was preserved in captivity with just 14 […]
Reproductive status of cheetahs (Acinonyx jubatus) in North American Zoos: The benefits of physiological surveys for strategic planning
Abstract 10.1002/zoo.1430120107.abs Under the mandate of a Species Survival Plan (SSP), reproductive status was assessed in 128 cheetahs maintained in 18 different institutions in North America. A mobile laboratory research team evaluated cheetahs using anesthesia, serial blood sampling, electroejaculation (males), and laparoscopy (females). Biomaterials were also collected for parallel studies of genetics, nutrition, and health. […]
Invited review: Cessation of lactation: Effects on animal welfare
The forced cessation of milk production, or dry-off, is a routine management practice in dairy cattle, sheep, and goats. This practice initiates a dry period, during which the animal is not milked. Milking begins again after parturition. Most of the literature on the dry period has focused on how various drying-off strategies affect milk production […]
An Investigation into the Human Element of On-farm Animal Welfare Incidents in Ireland
A previous study on key farm performance indicators for animal welfare incidents in Ireland provided anecdotal evidence to suggest that farm animal welfare standards are often underpinned by social and human health-related factors among farmers. The present study took an exploratory approach to identify these factors and how they influence farm animal neglect. Semi-structured interviews […]
