Suckling: developmental indicator of genetic obesity in mice.

abstract：:This paper describes a three-part study of the parenting behaviors of 6 family groups of Cebuella pygmaea (pygmy marmosets). In the first part, the parenting patterns of undisturbed family groups housed under laboratory conditions were scored throughout the first 10 weeks following the birth of their second infant(s)....
