Abstract
Suitability of Dorset Nilagiri crossbred lambs for intensive system of management was evaluated. Thirty-six (36) Dorset
Nilagiri crossbred lambs were randomly allotted to two groups of 18 lambs (9 ram and ewe lambs) each with group A under
intensive and group B under semi intensive system of management. Lambs under intensive and semi intensive system of
management were provided with 200 and 150 grams concentrate per day per animal from three to six months, 300 and 200
grams per day per animal from six to 12 months respectively. The Hogget, nine months and yearling weight (17.10±0.59,
23.99±0.68 and 27.83±0.63 vs. 14.51±0.59, 18.36±0.68 and 20.60±0.63 kg) were significantly higher (P<0.01) in group A
lambs. Lambs from group A, had significantly (P<0.01) higher overall body weight gain and ADG (15.99±0.36 kg and
59.31±1.30 g) than lambs from group B (9.25±0.36 kg and 34.17±1.30 g). Among the three stages, the ADG highest during
6-9 months in Group A ewe lambs (87.17±4.76 g). Significant reduction in ADG was observed during 9-12 months. Wool
yield was significantly higher in group A lambs.
