Maternal neglect in Tph2-deficient mice

Mother genotype	Number of dams	Litter size	Number of pups born	Number of pups survived until day 5	% survival	Number of dead litters on day 5
Control	n = 23	10.13 ± 0.45	233	228	97.9%	0/23
Tph2−/−	n = 29	9.28 ± 0.48	269	149	55.4%	11/29

Tph2⁻⁻ and control females (mixed background) were mated with NMRI (wild type) males and separated into single cages when visibly pregnant. The number of pups was counted on the day of birth (day 0) and at day 5. Litter size is given as average ± SEM.
