Det er vanskelig å si om rottemor trenger ekstra sesamfrø i ammeperioden uten å vite hva blandingen din består av (og regne ut kobberinnholdet :crazy: ) En mulig løsning er jo å skaffe et fullfór som inneholder det hun trenger, men det tar alltid litt tid. For sikkerhets skyld tror jeg at jeg ville laget litt grøt til henne med sesamfrø blandet inn. Det kommer hun nok til å like

Så var det lillegutten. Jeg vet ikke hvor liten han er, og hvor lenge han kan gå med moren og muligens tanten med tanke på ny drektighet. Det er noen andre problemstillinger her også:
http://www.ratbehavior.org/CommunalNesting.htmFamiliar sister pairs have another kind of inequality. The second-born litter of sister pairs is at a disadvantage compared to the first-born litter, and tends to suffer higher mortality. This occurs because in pooled litters of different ages the younger, smaller litter is forced to compete with the older, larger litter for milk. Another problem is that the older litter suckles at their aunt's teats before she gives birth. Such prepartum nursing renders her teats unusable to her own babies when they are born. Therefore, her own litter can only nurse from the first mother. So, not only are the second-born infants smaller and less competitive than their bigger cousins, they can only nurse from one of the two mothers.
If litters are not synchronized, with an age gap of more than two weeks between the two litters, the mortality of the second litter tends to be very high. The older litter invades the younger litter's nest, tramples and injures the young, monopolizes the mother's milk and damages her teats. Under these conditions, over two thirds of second-born pups die within a few days. Those few second-born pups that survive tend to have higher weaning weights, however.
However, if litters are synchronized (age gap of less than two weeks) and mothers of newborns don't nurse the older pups for several days, communal nesting may not increase pup mortality. In this case, birth synchrony may benefit the older litter without harming the younger litter: the first-born pups in this situation weigh more when they're weaned. The second-born pups experience no weight advantage, and survival of the litters isn't significantly increased.
Heldigvis er han bare en, og hvis de nyfødte faktisk får melk nå virker det som om den nybakte mammaen har sluppet å få nipplene ødelagt.
