DOI:Coming soon...

Abstract:

A total of 58 Frieswal heifers from fi ve different artifi cial insemination (A.I.) centres were selected to study 14 biometric traits.
The overall least- squares means for 58 heifers were 117.3 ± 2.1 cm for BL, 109.7 ± 1.5 cm for HAW, 141.4 ± 2.8 cm for CG, 146.4 ± 3.1 cm for PG, 40.9 ± 0.9 cm for FL, 27.9 ± 1.0 cm for FW, 18.1 ± 0.4 cm for EPL, 65.7 ± 1.2 cm for HE, 34.3 ± 1.6 cm for HK, 105.7 ± 1.5 cm for HPB, 110.7 ± 1.7 cm for HHB, 4.61 ± 0.26 mm for ST, 224.3 ± 11.3 kg for BW and 3.02 ± 0.09 m2 for BSA respectively. Higher values for various biometric traits were observed in Pantnagar A.I. centre. Higher values for various traits were observed in heifers reared by farmers having herd size up to 3 AUE, and also for the heifers reared by landless farmers. Land holding also had a signifi cant effect on FW. However, there was no signifi cant effect of AI centre, education level and season of birth on any of the traits and the majority of the heifers of this age group were pregnant
