Feeding management and milk production in organic and conventional buffalo farms

摘要

Abstract The feeding management, milk yield and milk composition were investigated in two adjacent buffalo farms, one organic certified (on average, 220 lactating buffalo cows) and one conventional (on average, 314 lactating buffalo cows) located in the Sele Plain (southern Italy). Milk samples from the two farm were collected twice a month during the period from June to November 2006. Milk production was also recorded. The investigated milk components were the content of protein, fat, lactose, urea and the number of somatic cells. The following features about the feeding management of lactating buffalo cows were recorded during monthly farm visits: feed used, herbage utilization, ration composition. Fat and protein correct milk yield was higher in conventional farm than in organic one, but milk components were similar between the farms. The greatest differences were found in the somatic cell count, lower in organic milk than in conventional one, and the urea content, which was higher in organic milk than in conventional farm, but still within the normal range reported for buffalo milk.
