Abstract:
Investigation was undertaken to study the effect of non-genetic factors on production traits of 160 Gir cattle during 2012 to 2020 at Gir cattle project of College of Veterinary and Animal Science, Navania, Vallabhnagar, Udaipur (Rajasthan). The overall least-squares means of Lactation milk yield (LMY), Lactation length (LL), 305 days milk yield (305DMY), Peak yield (PY) and Days to attain peak yield (DPY) were 1546.82±36.06 kg, 273.83±5.01 days, 1839.34±39.53 kg, 10.26±0.14 kg and 32.29±1.11 days, respectively. Period of calving had highly significant (P≤0.01) effect on peak yield and days to attain peak yield. Season of calving had highly significant (P≤0.01) on peak yield and significant effect (P≤0.05) on days to attain peak yield. Parity of animal had highly significant (P≤0.1) on days to attain peak yield and peak yield.
