Abstract
Objective: The objective of this study was to observe the effect of maternal deprivation on somatic growth of wistar
rat pups viz. Body weight, nose-rump length, tail length and head length.
Materials and method: 5 days old 50 rat pups were studied dividing equally into control and experimental groups.
Experimental group (N=25) of rats were maternally deprived 1-4 hours twice daily till the weaning period. Body
weight and measurement of body parts were recorded at 4 days interval till 29th day. Recorded parameters were
statistically analysed.
Result: The result of this study revealed that maternal deprivation stress produces significant effect in the body
weight, nose-rump length and tail length from D9 till the study period whereas head length insignificantly affected.
Conclusion: MD stress has profound effects on somatic growth and found irreversible even after withdrawal for a
period of 8 days.
Key words: Maternal deprivation, stress, body weight, somatic growth, preweaning period
