Correlation of body condition score, weight, measurements and effect of parity and stage of lactation on milk parameters of Gir cows

Abstract

Experiment was conducted on 100 Gir cows of different parity and stage of lactation maintained at Ashti Dairy Farm, Ashti taluka Partur, district Jalna of Maharashtra state. The present experiment was carried out to know the effect of parities and stage of lactation on milk parameters <italic>viz</italic>; WeeklyMilk Yield (WMY), WeeklyFat CorrectedMilk Yield (WFCMY), Fatand Solid Not Fat (SNF) percent and correlation between Body Condition Score (BCS), Body Weight (BW) and body measurements viz; height at wither, height at hook, heart girth and body length with milk parameters. The Least Squares Analysis of Variance has revealed significant effect of parity on the WMY, WFCMY and Fat percentage whereas, significant effect of stages of lactation on the WMY and WFCMY of Gir cows. The positive to negative significant correlation coefficients of body condition score with WMY (0.110); Height at wither with WMY (0.131) and Fat percent (-0.156); Hearth girth with WMY (0.125) and Fat percent (-0.155) and Body length with Fat percent (-0.139) respectively.
