Abstract:
The present study was aimed to assess the effect of non-genetic factors on production and reproduction traits in Badri cattle. The study assessed the production and reproduction traits of 147 calving records of Badri cattle , spread over a period of 7 years from 2014-2020, at Instructional Dairy Farm, G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India. Least-square maximum likelihood programme was used to analyse the effect of non-genetic factors (NGF) viz. parity number of animal, season of calving and period of calving on production and reproduction traits viz. total milk yield (TMY), peak yield (PY) and daily milk yield (DMY), service period (SP), dry period (DP) and calving interval (CI) respectively. Effect of animal’s parity number was significant (P <0.05) on TMY, PY, DMY and SP. Season of calving was found to be significant on PY (P <0.05). Effect of period of calving was significant (P <0.05) on DMY and (P <0.01) on TMY. Thus, it can be asserted that non-genetic factors have significant effect on the production and reproduction traits in Badri cattle. It is pertinent to pre-adjust the data of environmental factors for evaluating genetic parameters of production and reproduction traits in dairy cattle.
Highlights
- Non-genetic factors significantly affect production traits in Badri cattle.
- Production traits viz.TMY, DMY and PY significantly increase with increasing parity number.
- Badri cattle performs better in reproduction traits and lesser in production traits.
