The serow (Capricornis sumatraensis) is a critically endangered species. The objectives of this study were to evaluate ejaculate quality in captive males, and to investigate and characterize sperm morphology. Semen was collected using electroejaculation. Mean (+/-S.D.) seminal characteristics were: semen volume 2.3+/-0.8 mL, pH 7.8+/-0.4, and osmolality(More)
Chinese goral (Naemorhedus griseus) are a threatened species in Thailand and the focus of captive breeding for possible reintroduction. However, little is known of their biology or what factors in the captive environment affect welfare. Our objective was to determine the impact of gender, season, and management on goral adrenal activity. We hypothesized(More)
There is no information on the endocrinology of Chinese goral (Naemorhedus griseus), a high priority species for captive breeding and reintroduction in Thailand. This study characterized fecal androgen and glucocorticoid metabolites in male goral at Omkoi Wildlife Sanctuary to investigate seasonal relationships. Fecal samples were collected 3 days/week for(More)
The Indochinese leopard (Panthera pardus delacouri) population, included in CITES Appendix I, has been declining for decades. Proper gamete preservation condition is critical for breeding programme management using artificial insemination or in vitro fertilization (IVF). The present study aimed at investigating the impact of post-thawing treatment of(More)
The Asian tapir (Tapirus indicus) has been classified as Endangered on the IUCN Red List of Threatened Species (2008). Genetic diversity data provide important information for the management of captive breeding and conservation of this species. We analyzed mitochondrial control region (CR) sequences from 37 captive Asian tapirs in Thailand. Multiple(More)
Captive breeding of clouded leopards (Neofelis nebulosa) is challenging because of mating incompatibility, high incidence of teratospermia in males, and inconsistent ovulation patterns in females. Assisted reproductive techniques, therefore, are necessary to overcome these issues and maintain the genetic diversity in the captive population. The objective(More)
The Malayan tapir (Tapirus indicus) is classified as a preserved animal of Thailand. It is listed as an endangered species on the 2008 IUCN red list and also by the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Blood samples from captive Malayan tapirs (n = 20, 10 males and 10 females) from five zoos under the Zoological(More)
Asian tapir (Tapirus indicus) is categorized as Endangered on the 2008 IUCN red list. The first full-length mitochondrial DNA (mtDNA) sequence of Asian tapir is 16,717 bp in length. Base composition shows 34.6% A, 27.2% T, 25.8% C and 12.3% G. Highest polymorphic site is on the control region as typical for many species.
To date, there is no information on gonadal steroidogenic activity of female goral (Naemorhedus griseus), a threatened species of Thailand. Captive goral populations have been established to produce animals for ex situ conservation and reintroduction, but as yet none are self-sustaining. The objectives of the present study were to (1) determine the(More)
Propagating genetically valuable individuals through oocyte collection, in vitro fertilization (IVF) and embryo transfer is critical to maintain sustainable populations of the endangered Eld's deer. The objectives of this study were to assess the impact of exogenous FSH injections on (1) the number and in vitro competence of oocytes collected and (2) the(More)
