Description
Summary:	This research was carried out in the milk production plants for 10 weeks (5 during the dry season and 5 during the rainy season in Medellín, Colombia). Samples of raw (fresh) milk were taken from Holstein cattle and fresh farmer cheese was produced through enzymatic coagulation. For the milk and the cheese, the physicochemical characteristics and nutritional quality, were evaluated for both seasons. For parameters such as the casein and the ash content, the non-fat milk solids showed a confidence interval that fluctuated between 8.3% and 8.7% (with an α=0.05), which is comparable to that reported by the Colombian legislation; however, unusual results were identified within the registered periods, especially at the transition period between rainy and dry period (7.89% non-fat solids). The obtained yield averages were significantly higher in regards to those reported by various authors, while those found for the other studied parameters had results similar to those proposed in the literature. The evaluation and determination of high nutritional value factors in food, such as the protein percentage and the essential amino acids profile, allow for the improvement of quality based milk payment systems that can be applied nationwide and that are based on the initial proposal of Fedegan and the Republic of Colombia
