Litter size ranges from two to nine young, with an average of five. (pa.gov)
Weight2
EGME treatment had no effect on maternal weight gain during gestation, but did affect the reproductive outcome in a dose dependent manner. (cdc.gov)
EGME treatment also reduced pup weight, decreased litter size, and significantly prolonged gestation. (cdc.gov)
Average2
Sociable and form packs of up to 40 members, although the average pack size is between 7 and 15. (binderparkzoo.org)
The higher extinction risk for larger species could result from body size influencing vulnerability to different human activities, such as killing, habitat destruction and fragmentation, and the small size of natural reserves. (scielo.br)

Dose1
Dose levels of 50 and 75mg/kg EGME reduced delivery of litters by 50 and 100 percent, respectively. (cdc.gov)
Estimate1
Therefore, managers must often rely on population indices because of the difficulty in obtaining adequate data to estimate coyote population size over a large landscape such as an entire state. (azgfd.com)
Weeks1
Body composition of offspring at 5 and 8 weeks of age was similar regardless of HMB treatment during gestation. (bvsalud.org)
