Abstract:

S.K.N. College of Agriculture, Jobner dairy farm was purposively selected for the study. The selection of cows was done randomly. The data of 18 F1 crossbred cows (Th x HF) those had completed three consecutive lactation at the college dairy farm was collected for carrying out the present study. This herd is being maintained at S.K.N. College of Agriculture, Jobner dairy farm under semi-arid condition. Data was collected from the record of college dairy farm over a period of eight years (1994-2001). The production performance of 18 F1 crossbred cows maintained in S.K.N. College of Agriculture, Jobner was studied for total lactation milk yield during first, second and third lactation and corresponding lactation length during first, second and third lactation. To estimate the production traits in F1 crossbred cows in least square estimation method was used for statistical analysis of data to arrive the conclusions. In general, total F1 crossbred (Th x HF) cows are presented on the college dairy farm. The average milk yield during first, second and third lactations were 2631.91±62.83, 2562.09±59.57 and 2592.39±54.04 in liters respectively. The average lactation length during first, second and third lactations were 373.13±15.09, 363.19±32.19 and 372.50±32.91 in days respectively. The milk yield during first, second and third lactation varied among different cows. The mean values for third lactation were higher than second lactation but lower than first lactation. The first lactation was highest milk yield and lactation length. Milk yield increases with increasing lactation length. Least square analysis of variance showed that lactation length had significant influence upon lactation milk yield in all crossbred cows. The performance of the F1 Tharparkar x HF crosses can possibly be the best during first lactation. This could be done to the influence of hybrid vigour that reflected in crossbred cows maintained in tropical climatic condition.
