摘要
The effect of two farming systems: organic system (OS) and conventional system (CS) was compared for physico-chemical composition and cheese-making aptitude of milk. The stocking rate was 4 in OS and 6 ewes ha(-1) in CS. Individual milk yield resulted significantly higher in OS than CS. No significant differences were found on milk composition, only casein content was higher in CS than OS (4.44% vs 4.20%; P<0.05). The lactodinamographic characteristics of milk in the two groups showed differences only for R: 25.10 (OS) Vs 28.88 min (CS; P<0.05). Cheese yield and fat recovery rate was not affected by the fanning system while the protein recovery rate tended to be higher in CS than OS (75.94% vs 74.39%).
