Transitory disturbances in growing lactating rabbits after transient doe-litter separation.
To determine the effect of a transient doe-litter separation (48 h) on milk production and feed intake from 1 to 21 days post-partum, a control group (C) in which litters had free access to nursing, and a biostimulated group (B) in which litters were separated from their does from d 9 to d 11 post-partum were used. Total milk production was higher in (C) than in (B) does (5090+/-1.1 g vs. 4593+...
متن کاملResponses to Separation in Mother
The behavioral and hormonal responses of mother and infant squirrel monkeys (Saimiri sciureus) were examined to assess temporal and environmental factors that influence the response to separation. In two experiments evaluating the effects of 1-, 3-, 6-, and 24-hr separations, it was found that signs of infant behavioral agitation decreased over time, whereas adrenocortical activation persisted ...

15 صفحه اولNutritional restriction in lactating primiparous sows selectively affects female embryo survival and overall litter development.
This study explored the possibility of sex-specific effects on embryonic survival in primiparous sows subjected to restricted feed intake during the last week of lactation and bred after weaning (Restrict; n = 16), compared with control sows fed close to ad libitum feed intakes (Control; n = 17). Restrict sows were in a substantial negative net energy balance at weaning, and lost 13% of estimat...
