unknown. ABSTRACTAn investigation was undertaken to study the effect of season, parity, type of birthand teat abnormality on milk yield of local goats of Rohilkhand region. A total of 32 doeswere selected for the experiment, and were grouped according to season (rainy and winter),parity (primiparous and multiparous), type of birth (single and twin), and type of teatabnormality (normal teat and abnormal teat). All does were milked twice daily and milk yieldwas recorded up to 90 days. It was found that average daily milk yield (ADMY) and total milkyield of 90 days (TMY) were significantly (P<0.01) higher in rainy season (0.726±0.05 L ;65.32±8.81 L) than winter season (0.657±0.02 L ; 57.91±3.51 L). Regarding parity, ADMY andTMY were significantly higher (P<0.01) in multiparous does (0.754±0.02 L and 66.76±3.97 L)than primiparous does (0.515±0.03 L and 45.73±3.18 L). Average TMY for single kidded andtwin kidded does were 51.37±4.05 L and 65.89±4.53 L, respectively and it didn’t differsignificantly. Presence of supernumerary teat (16%) was the prominent form of abnormalityobserved followed by bifurcal teats (4%) and asymmetrical udder (4%). Average milkproduction in does with teat abnormality was non-significantly lower than the normalanimals. It can be concluded that milk production vary significantly with the season andparity in these local goats.Key words : Goat milk, Parity, Season, Teat abnormality.
