Characteristics of estrus, mating, and pregnancy were studied in captive fennec foxes. The monestrous cycles had mean intervals of 9.9 (!1.2) months, whether or not pups survived to weaning. Proestrus, judged by vulval swelling, began 6.5 (!0.7) days before estrus and was not accompanied by sanguineous discharge. Percentage cornified epithelial cells in vaginal smears increased at the time of e...

The effects of exogenous melatonin on reproductive performance of 737 Polypay and Polypay-cross ewes were evaluated during a late March and April breeding period. Different concentrations (2 or 10 mg) routes of administration (fed vs implanted) and durations of administration (20 or 40 d before breeding) were studied. Estrus was synchronized in all ewes using 60 mg medroxyprogesterone acetate (...

BACKGROUND: Inbreeding is one of the major problems of small size herds of red deer in refuge wildlife parks. OBJECTIVES: The aim of the present study was to use estrus synchronization technique in red deer (Cervus elaphus) based on natural mating to control the dominancy and social rank of stags and inbreeding. METHODS: In this study, hinds (n=6) were captured and caged at breeding season (ear...
