ABSTRACT
The data for the present investigation pertained to 1647 observations of lactation length (LL) on Malvi cattle maintained at Govt. Cattle Breeding Farm, Agar, District Shajapur (M.P.), covering a period of 48 years from 1962 to 2009. The least squares analysis of variance revealed the mean lactation length in these cows to be 263.85±6.95 days and the trait was significantly affected by sire (P< 0.01), period of calving (P< 0.01), season of calving (P< 0.01) and parity of the cow (P< 0.01). Although, inbred cows had lower lactation length as compared to non-inbred cows, the effect of inbreeding was not significant. Heritability estimate for lactation length in the herd was obtained as 0.08±0.11. It was concluded that to improve the lactation length in this herd, ameliorative managerial practices should be adopted along with avoidance of inbreeding.
