Twenty four does (Soviet Chinchilla × New Zealand white) of average 1.65±0.25 kg body weight were randomly distributed into four groups of six animals each. The animals in group T₁ were fed commercial pellet whereas in groups T₂, T₃ and T₄ they were fed commercial pellet and fresh para grass in the ratio of 75: 25, 55: 50 and 25: 75 on DM basis, respectively. Each doe was weighed at weekly interval from birth to 16 days post partum. The conception rates in T₂, T₃ and T₄ were 100, 75 and 66.66%, respectively. The gestation length was similar in all the groups. Both litter weight at birth (228g) and at weaning (1173g) were highest in group T₂. The litter size at weaning was 5.00 in T₂ followed by T₄ (3.40) and T₁ (2.89). Average daily gain (g/d) of kids was 6.99, 8.06, 8.64 and 8.13g in T₁, T₂, T₃ and T₄ respectively. The survival rate in this study ranged from 62.9 to 97.6%.
