The period of calving had non-significant effect on SP in FG and R genetic groups and significant in FJG group. The effect of generation had significant effect on CI. The overall generation CI in FG, FJG and R group were 414.34 ± 3.88, 395.26 ± 4.23 and 352.74 ± 16.89 days, respectively. The Generation wise least squares means for highest CI in FG, FJG and R group observed in G8 (435.63 ± 23.63), G5 (421.32 ± 8.29) and G1 (400.68 ± 9.85) days, respectively. While the lowest CI observed in G5 (402.57 ± 7.37), G9 (363.66 ± 26.21) and G5 (267.33 ± 77.61) days, respectively. The effect of genetic group was significant on CI of group. The CI in R group was significantly lowest than FG (409.28 ± 2.67) and FJG (403.22 ± 2.47), respectively. The overall least squares means of LMY in FG, FJG and R group cows were 3487.35 ± 28.08, 3240.84 ± 25.99 and 2636.12 ± 52.23, respectively.EnglishThesis
