Abstract :This study aims to determine the environmental factors effected to lactation length insert ignore into journalissuearticles values(LL);, lactation milk yield insert ignore into journalissuearticles values(LMY);, calving intervals insert ignore into journalissuearticles values(CI); of Anatolian buffaloes in Bartın. 1511 milk yield data belonging to 762 Anatolian buffaloes and 957 CI data belonging to 543 Anatolian buffaloes used in this study which has been reared different environmental conditions. The least minimum squares method was used for determining the effect of environmental factors, and a Tukey multiple comparison tests were used for comparison. LL, LMY, and CI mean and their standard deviations were 260.26±1.33 d, 1035.5±8.21 kg, and 426.35±2.91 d, respectively. Calving year, season, calving age, and lactation number’s effect on those parameters were investigated. The effect of calving year insert ignore into journalissuearticles values(P<0.001); and season insert ignore into journalissuearticles values(P<0.01); on LL; calving year insert ignore into journalissuearticles values(P<0.001); and calving age insert ignore into journalissuearticles values(P<0.05); on LMY; calving age and lactation number insert ignore into journalissuearticles values(P<0.001);, calving age insert ignore into journalissuearticles values(P<0.01);, season insert ignore into journalissuearticles values(P<0.05); on CI were found statistically significant. Meanwhile, a high positive phenotypic correlation was calculated between LMY and LL insert ignore into journalissuearticles values(r=0.66, P<0.001);. There are no adequate studies related to the environmental factors influencing lactation length, lactation milk yield, calving intervals of Anatolian buffaloes. It was concluded that obtained data relevant to these environmental factors will contribute to increasing yield parameters at buffalo farms via using stud selections and breeding studies as well as related researches.
