| pubmed-article:1485732 | pubmed:abstractText | Rhesus and squirrel monkeys have been fed a semisynthetic diet at approximately ad libitum or 30% reduced levels for 3.5 (rhesus group 2) to 4.5 (rhesus group 1 and squirrel) years. Animals have maintained excellent health status as determined by physical examinations, hematology, and blood chemistry. While relative rates of body weight gain in restricted group 1 rhesus and squirrel monkeys have been markedly reduced, DR effects on crown-rump length (body height) have been variable. In addition, numerous physiological and biochemical parameters have been measured, and several exhibit significant cross-sectional age effects. Interestingly, several of these also exhibit possible species and genotype (group 1 and 2 rhesus) differences. A number of physiological parameters are emerging that might be altered by DR; however, further explanation of these effects awaits more extensive and detailed analyses. | lld:pubmed |
