Improving the productivity of breeding colonies of Mongolian gerbils (Meriones unguiculatus).
The productivity of breeding colonies of Mongolian gerbils can be substantially enhanced by using as breeding stock only the 40% of females that exhibit vaginal opening before reaching 25 days of age. Early-maturing females are more likely to breed successfully on first pairing. The lifetime fecundity of early-maturing females is more than twice that of their late-maturing sisters. In those cas...
متن کاملMolecular characterization of different breeding groups of outbred Mongolian gerbils (Meriones unguiculatus)
Two RAPD primers and 15 protein biochemical markers were examined to assess the zygosity (hetero/homozygocity) and per cent polymorphisms in monogamous (IM: IF) and triogamous (1M:2F) breeding groups of outbred Mongolian gerbils (Meriones unguiculatus). No polymorphism and heterozygosity were found in RAPD as well as biochemical markers in monogamous groups, whereas both primers in RAPD (%P=55%...
متن کاملVariations of serum estradiol and progesterone levels during consecutive reproductive states in Mongolian gerbils (Meriones unguiculatus).
Serum estradiol (E2) and progesterone (P4) levels were measured by chemiluminescence immunoassay (CLIA) during consecutive reproductive states in Mongolian gerbils. The results show that E2 and P4 levels throughout the estrous cycle in Mongolian gerbils peaked at proestrus and estrus, respectively. During gestation in primiparous and multiparous gerbils, E2 levels reached a small peak on day 6 ...
متن کاملVariable infectivity of human-derived Giardia lamblia cysts for Mongolian gerbils (Meriones unguiculatus).
To determine whether gerbils can be used as a suitable animal model for giardiasis, we attempted to infect Mongolian gerbils with cysts of Giardia lamblia isolated from the stools of 10 humans with symptomatic and asymptomatic giardiasis. We obtained 100% infection with one isolate (CDC:0284:1), as evidenced by the presence of numerous trophozoites in the intestines of the gerbil and cysts in t...
متن کاملHormonal regulation of agonistic and affiliative behavior in female mongolian gerbils (Meriones unguiculatus).
Ovarian steroids and oxytocin (OT) have been implicated in the regulation of social behaviors. The purpose of the present study was to examine hormonal substrates of aggression and affiliation in the female Mongolian gerbil (Meriones unguiculatus), a highly social, monogamous rodent. Sexually naive adult females were paired with sexually experienced males for 48 h and their interactions videota...
