| Summary: | This study investigated the effect of different farming systems and lactation stages on the physicochemical characteristics, somatic cell count (SCC), and total bacterial count (TBC) of milk from Skopelos goats. This study was conducted over two consecutive lactation periods on two commercial farms in Greece, an extensive system on Skopelos Island and an intensive system in the Attica region, involving 237 goats of shared genetic background, thereby minimizing genetic variability and strengthening the validity of the comparisons between the production systems. Higher milk yields were observed in the extensive system (0.98 vs. 0.85 kg/day), while milk from this system also had a higher protein (3.57% vs. 3.47%; <i>p</i> < 0.001) and casein content (2.72% vs. 2.57%; <i>p</i> < 0.001), which are traits favorable for cheese production. Fat content peaked during mid-lactation (4.83%; <i>p</i> < 0.05) and remained unaffected by the farming system. Lactose declined from early (4.74%) to late lactation (4.42%; <i>p</i> < 0.001). Both SCC and TBC were significantly elevated in the extensive system (<i>p</i> < 0.001), possibly due to hand milking, environmental exposure, and less-controlled hygiene conditions. These findings highlight a trade-off between the nutritional advantages of extensive systems and challenges related to milk hygiene. A balanced approach, optimizing both quality and sustainability, is recommended. |
