Abstract

In this study, traits of the lactation curves of N ıı tive Buffaloes raised at the Afyon Kocatepe State Farm were determined. The shape and type of lactation curves were d .scribed by the parameters of Gamma function of Y, = A tb e-ct. 10.4 percent of lactation curves were atypical. The dis:ributions of typical and atypical lactation curves ware depended upon the lactation season P0.05 depended upon the lactation number. Least squares means were found to be 2756.5±0.403 g for A parameters beginning yield , 0.713±0.128 for b parameters coefficient of rising , 0.15174t0.06033 for c pa •ameters coefficient of decreasing , 7.27±0.12 for S parameters persistency , 6086.75±146.77 g for Y,„a„ parameter. Average of maximum daily peak yield , 104.56±36.22 days for Ta,ax parameters average of daily peak yield length , respectively. Effect of calving year on Y,,,ax were highly significant F
