Aim of study: To enhance the viability of goat farms in Mediterranean mountain areas, studies have proposed strategies to improve the marketing of their animal products. The primary aim of this work was to provide an overview of the commercial traits and antioxidant composition of milk produced on Payoya farms. A second aim was to assess the relationships between the antioxidant capacity (TAC) and the hygiene-sanitary parameters in milk.
Area of study: Sierra de Grazalema Natural Park (Southern Spain).
Material and methods: The commercial traits (total solids, fat, protein, lactose, bacterial and somatic cell counts) and TAC of milk were determined monthly throughout the year. Milk samples were collected from sixteen Payoya farms under grazing-based management systems classified into three clusters
Material and methods: The commercial traits (total solids, fat, protein, lactose, bacterial and somatic cell counts) and TAC of milk were determined monthly throughout the year. Milk samples were collected from sixteen Payoya farms under grazing-based management systems classified into three clusters (Low-productivity grazing farms, More instensive grazing farms, High-productivity grazing farms).
Main results: No significant differences were found between clusters in the milk quality. Principal changes were observed in the milk composition in different months due to the variation in the lactation stage and differences in feeding regimens. The negative correlation between the TAC and the somatic cell count contributes to the important role of antioxidants in maintaining optimal udder health. Vitamin A could be involved in this antioxidant mechanism due to the positive correlation between the TAC and retinol determined in a previous study.
Research highlights: The information generated on the quality of goat milk would contribute to establishing the records of the traceability system to guarantee that the animal products obtained are of the Payoya native breed.
