Assessment of motility, acrosomal integrity, and viability of giant panda (Ailuropoda melanoleuca) sperm following short-term storage at 4°C

Abstract 10.1002/zoo.10113.abs Short-term cool storage of semen affords many of the same benefits as cryopreservation, without the extensive cryoinjury to sperm associated with freezing. Semen storage for artificial insemination (AI) is an integral part of giant panda captive breeding programs. AI functions to generate offspring from males that have never bred, are underrepresented, or are […]

Reproductive status of endemic felid species in Latin American zoos and implications for ex situ conservation

Abstract 10.1002/zoo.10093.abs Reproductive evaluations were conducted on 185 male cats representing eight endemic Latin American species that were maintained in 44 zoos and private facilities in 12 Latin American countries. Reproductive assessments (testicular measures, ejaculate quality, and blood testosterone/cortisol concentration) were used to establish normative values for large- and small-sized cats in Latin American collections. […]

Reproductive inefficiency in male black-footed ferrets (Mustela nigripes)

Abstract 10.1002/1098-2361(2000)19:63.3.CO;2-M The black-footed ferret (Mustela nigripes), once considered extinct, has benefited from captive breeding and subsequent reintroduction into native habitat. A high proportion of females (>90%) exhibit estrus in captivity during the spring breeding season. However, many males considered to be prime-breeding age (1–3 years old) fail to sire offspring. Breeding records in 1995 […]

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. […]

Influence of nutrition on the quality of semen in Jaguars Panthera onca in Brazilian zoos

In Brazilian zoos wild felids in captivity are generally fed meat. However, considering the basic nutritional needs of the domestic cat Felis catus, beef may be deficient in calcium, phosphorus, copper, manganese, vitamins A, D and E, thiamin, folic acid and biotin. The aim of this study was to determine the influence of vitamin (A, […]
