The success of a dairy industry in India is much dependent on buffaloes and the level of production and reproduction traits. These performance traits depend on several genetic and non-genetic factors which introduce biasness in the estimation of genetic value of performance traits. In the absence of accurate phenotypic value of milk production traits, it becomes difficult to estimate genetic parameters of the traits which determine the optimum selection criterion for planned improvement programme of the animals. Also genetic evaluation of animals require the assumption that phenotypic measurements are adjusted for non-genetic factors that can affect production efficiency and reproduction traits (ex. Year/period of calving, season of calving, calving order, age at calving, length of lactation) to obtain accurate estimates of the genetic parameters and the breeding value of animals. This review summarizes the means/averages of milk production and reproduction traits, effect of non-genetic factors on performance traits in buffaloes. The production traits reviewed were Total Lactation Milk Yield (TLMY), 305 Day Milk Yield (305DMY), Peak Yield (PY), Lactation Length (LL) and Dry Period (DP). The reproduction traits reviewed were Service Period (SP) and Calving Interval (CI). In order to improve productivity, obtain efficient reproduction and health of dairy animals it is necessary to develop an understanding of the factors affecting milk production, reproduction traits.
