Energy and mineral nutrition and water intake in the captive Indian rhinoceros (Rhinoceros unicornis)

Abstract 10.1002/zoo.20032.abs In the captive Indian rhinoceros (Rhinoceros unicornis), two disease complexes with a high incidence—chronic foot problems and uterine leiomyomas—may be linked to excess body weight (BW). In this study, intake and digestion trials were conducted (by means of 7-day weigh-backs, and 5-day total fecal collections, respectively) with 11 Indian rhinoceroses at four zoological […]

Serum and fecal steroid analysis of ovulation, pregnancy, and parturition in the black rhinoceros (Diceros bicornis)

Abstract 10.1002/(SICI)1098-2361(1997)16:23.3.CO;2-Z Studies were conducted to determine: (1) if fecal hormone metabolite concentrations correlated with serum estrogen and progesterone concentrations, follicular activity and reproductive behavior in the black rhinoceros (Diceros bicornis) and (2) if threshold values of respective fecal metabolite concentrations correlated with pregnancy. Blood and fecal samples were collected, in conjunction with transrectal ultrasound […]

Urinary steroid evaluations to monitor ovarian function in exotic ungulates: VII. Urinary progesterone metabolites in the Equidae assessed by immunoassay

Abstract 10.1002/zoo.1430090502.abs A direct enzyme immunoassay (EIA) for non-specific urinary progesterone (Po) metabolites, utilizing a non-specific monoclonal antibody against pregnanediol-3-glucuronide, was evaluated for the purpose of assessing luteal function in equids. Urinary pregnanediol-3-glucuronide (PdG) and immunoreactive PdG-like conjugate (iPdG) concentrations, indexed by creatinine, were compared to plasma Po concentrations in non-conceptive ovarian cycles through two […]

Evaluation of season-related dietary changes on the serum profiles of fat-soluble vitamins, mineral, fatty acids, and lipids in the captive greater one-horned rhinoceros (Rhinoceros unicornis)

Circulating concentrations of fat-soluble vitamins A, D, and E, minerals, fatty acids, and lipids were quantified in five captive greater one-horned rhinoceroses (Rhinoceros unicornis) throughout two time periods, during which two diets were offered. Animals were fed mixed-grass hay and concentrate pellets while managed in barns for winter housing (April sampling, winter diet). During the […]
