The objective of this study is to investigate factors influencing infant survival in captive common marmosets. We investigated the influence of age-specific weight, litter size, caging, and the presence of helpers on survival to 6 months of age in 189 Callithrix jacchus infants. Infant survival was analyzed using Cox Proportional Hazards regression, and fitness functions were plotted to explore the relationship between survival and growth. Results indicate that weights at birth and 120 days… CONTINUE READING
