Abstract
The objective of this study was to investigate the effect of the previous calving intervals (CI) on milk yield (MY) in the current lactation for the Italian buffalo breed population. Data for 86,585 lactation records from the Italian Buffalo Breeders Association database, were analyzed. MY BLUPestimates were obtained by including in the Animal Model the fixed effects of age-parity, previous CI, and herdcontemporary- group. The MY solutions for the months of CI were analyzed with the linear regression model where CI in months was the explanatory variable. 59.66% of the lactation records had CI between 11 and 14 months. 37.91 % of the lactation records were distributed between 15 and 24 months. The smaller percentage of records showed CI greater than 24 months. This CI distribution may be, in part, the result of herd management strategies. Dairy producers try to shorten the CI of their herd in order to get the most profit from early con...
