'Collaborative' rearing of marmoset triplets.
نویسندگان
چکیده
A system of management is described in which all 3 offspring from triplet births to Callithrix jacchus can be successfully reared to weaning. Hand-rearing techniques are applied to the offspring in turn without depriving them of the maternal and family influences necessary for normal behavioural development.

Effects of Number of Lambs Suckled a N D S U P P L E M E N T a L Protein Source on Lactating Ewe Performance 1'2
Effects of number of lambs suckled and supplemental protein source on ewe performance were determined. Lactat ion performance of ewes nursing twin or triplet lambs was compared in Exp. 1 and 2. In Exp. 1, ewes giving birth to and nursing triplets produced 21% (P<.05) more milk/unit metabolic body weight, were 10% more efficient in the conversion o f feed to milk and produced 26% (P<.05) more kg...
متن کاملThe long-term impact of infant rearing background on the affective state of adult common marmosets (Callithrix jacchus)
Early life environment, including temporary family separation, can have a major influence on affective state. Using a battery of tests, the current study compared the performance of adult common marmosets (Callithrix jacchus), reared as infants under 3 different conditions: family-reared twins, family-reared animals from triplet litters where only 2 remain (2stays) and supplementary fed triplet...
متن کاملLong-term data on reproductive output and longevity in captive female common marmosets (Callithrix jacchus).
The common marmoset (Callithrix jacchus) is widely used in biomedical research, with many housed for breeding purposes world-wide. Significant variation in reproductive output among females has been found compared to other anthropoid primates. The present study explores this reproductive variation, focusing on potential predictors of dam longevity and litter size, as well as changes over time. ...
متن کاملOcular wavefront aberrations in the common marmoset Callithrix jacchus: Effects of age and refractive error
The common marmoset, Callithrix jacchus, is a primate model for emmetropization studies. The refractive development of the marmoset eye depends on visual experience, so knowledge of the optical quality of the eye is valuable. We report on the wavefront aberrations of the marmoset eye, measured with a clinical Hartmann-Shack aberrometer (COAS, AMO Wavefront Sciences). Aberrations were measured o...
متن کاملQuality of maternal and paternal care predicts later stress reactivity in the cooperatively-breeding marmoset (Callithrix geoffroyi).
Variation in the early postnatal social environment can have lasting effects on hypothalamic-pituitary-adrenal (HPA) axis stress responses. Both rats and macaque monkeys subjected to low quality or abusive maternal care during the early postnatal period have more pronounced HPA responses to environmental stressors throughout development and into adulthood compared to animals reared in higher qu...
