Complete nutrient composition of commercially raised invertebrates used as food for insectivoresAbstract A variety of invertebrates are commonly fed to insectivorous animals by both zoos and hobbyists, but information as to the nutrient composition of most commercially raised species is limited. Adult house crickets, house cricket nymphs (Acheta domesticus ), superworms (Zophobas morio larvae), giant mealwor... ... hiện toàn bộ

Urinary monitoring of adrenal responses to psychological stressors in domestic and nondomestic felidsAbstract The potential of assessing adrenal responses to psychological stressors through the radioimmunoassay of free cortisol in urine was examined in the domestic cat (Felis catus ) and in three nondomestic felid species (Felis geoffroyi, Felis bengalensis , and Felis concolor ). To dete... ... hiện toàn bộ

Assessing animal welfare: different philosophies, different scientific approachesAbstract Attempts to improve animal welfare have commonly centered around three broad objectives: (1) to ensure good physical health and functioning of animals, (2) to minimize unpleasant “affective states” (pain, fear, etc.) and to allow animals normal pleasures, and (3) to allow animals to develop and live in ways that are natural for the species. Each of these ob... ... hiện toàn bộ

Reproductive steroid hormones and ovarian activity in felids of the Leopardus genusAbstract Reproductive endocrine patterns were characterized in female ocelots (Leopardus pardalis ; n = 3), tigrinas (Leopardus tigrinus ; n = 2), and margays (Leopardus wiedii ; n = 2) housed in captivity in southern Brazil. Females were maintained as singletons and exposed to natural flu... ... hiện toàn bộ

Local adaptation, coadaptation, and population boundariesAbstract Coadaptation can occur either because of local adaptation in a geographically widespread population and/or because of intrinsic adaptation to the state of other genes or chomosomes. In either event, hybridization between animals with differently coadapted gene or chromosomal complexes can result in a decrease in fertility, viability, etc. in the initial hyb... ... hiện toàn bộ

Reproductive status of endemic felid species in Latin American zoos and implications for ex situ conservationAbstract 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‐ a... ... hiện toàn bộ

Reproductive endocrine responses to photoperiod and exogenous gonadotropins in the pallas' cat (Otocolobus manul)Abstract Fecal samples were collected for 14–26 months from three male and six female Pallas' cats (Otocolobus manul ) to examine gonadal steroidogenic activity in response to changes in photoperiod and treatment with exogenous gonadotropins. Females exhibited a seasonal anestrus from May–December, excreting consistently low concentrations ... ... hiện toàn bộ

Urinary steroid evaluations to monitor ovarian function in exotic ungulates: II. Comparison between the giraffe (Giraffa camelopardalis) and the Okapi (Okapia johnstoni)Abstract Ovarian activity in the female giraffe was evaluated during the nonfertile ovarian cycle and during the terminal stages of gestation. Progesterone metabolites, in the form of pregnanediol‐3‐glucuronide (PdG), were measured in daily random urine samples collected from four adult parous giraffes. The follicular phase averaged 4.0 ± 0.1 days in length (N = 12;... ... hiện toàn bộ

Hormonal induction of spermiation, courting behavior and spawning in the southern bell frog, Litoria raniformisAbstract We trialled the efficacy of various exogenous hormones to induce spermiation, courtship behavior, and spawning in the “endangered” southern bell frog, Litoria raniformis. Intralymphatic administration of Lucrin® , a synthetic nonapeptide luteinizing hormone releasing hormone (LHRH), was used successfully to ind... ... hiện toàn bộ
