The effect of calving season on milk production in water buffalo (Bubalus bubalis)

The influence of calving season on milk production and composition was studied in 16 adult (3rd lactation) water buffaloes from a single form in southern Italy over a 3 yr period. The data were separated into two groups according to calving season: group A of animals that calved from winter to spring and group B of those that calved throughout summer and autumn. Daily milk production and lactation length over the whole period (1997-2000) were higher (P<0.01) in group B than in A (9.11 vs. 8.55 kg and 275 vs. 258 d), but milk fat content was higher (P<0.05) in A than B (8.88 vs. 8.41%). No differences between groups were observed in milk protein content (4.7%). It was concluded that the calving season had little effect on the net income from this herd (In English)
