Resumo: | ABSTRACT The objective of this study was to determine factors affecting phenotypic characteristics related to milk production and reproductive efficiency of dairy buffalo. Phenotypic records of 2,459 Murrah, Mediterranean and crossbred buffaloes from the Embrapa Eastern Amazônia herd, from 1969 to 2013 were used. Traits included: total milk production during lactation (TMP), milk production corrected for 305 days (P305); cow weight at calving (CW), fat milk percentage (F), age at first calving (AFC), calving interval (CI), calf birth weight (BW), as well as lactation (LP) and service periods (SP). Most traits were affected by genetic group as well as year and season or interaction between them. Genetic group affected F, CI, SP and CW. Very young and older cows showed poorer production traits. There was interaction between season and year for F, CI and CW. Correlations traits were generally medium to low. The principal component analysis showed that higher fat milk percentage was associated with higher percentage of Murrah breed, longer lactation period and older cows. Phenotypic characteristics in buffaloes reared in the Brazilian Amazon were significantly affected by genetic and management factors. This information can be used to help build sustainable production systems for the region and guide farmer decisions. |
