Caracterização da produtividade e da qualidade do leite de búfalas na Zona da Mata Sul de Pernambuco

Abstract

This work had objective to characterize the production and constituent of buffalos milk in the southern Zona da Mata de Pernambuco and to evaluate the influence of environmental factors in the production characteristics. The data were proceeding of two farms totaling 246 animals. The farms were classified in two production systems (SP1 and SP2), in agreement with the management type. The dairy controls were performed monthly and all weights were accompanied by their samples for determination of milk constituents (fat, protein, lactose and total solids) and somatic cell count (SCC). The data consisted of milk yield (MY) on the control (kg /day) and milk yield corrected to 4%, milk yield during lactation, season of calving, orders of lactation, lactation length and yield of fat, protein, lactose and solids (kg) in lactation. Descriptive analyses of the variables and applied variance analysis and average test were accomplished (Tukey 5%) to evaluate the influence of SCC and season of calving in milk yield and milk constituents, and also the influence of the order of lactation and age calving in milk yield. The average SCC of milk was low and higher counts negatively influenced the yield of milk components. Environmental factorsinfluencing the milk production of buffaloes as well as the constituents of milk. It is concluded that the herds were in the stabilization phase with low daily production (4.78± 1.32 kg/day) and lactation length (230.84 ± 82.52 days).
