The effect of season and agro-ecology on physicochemical properties of cow's raw milk in Central and North-Western Zone of Tigray, Ethiopia

Year: 2024

Type: article

Abstract: C, respectively. Significant differences (p < 0.05) were observed in protein, solids-not-fat, lactose, and salt content among agro-ecologies, seasons, and sources of milk. Correlation analysis revealed positive correlations between specific gravity and solids-not-fat, protein, lactose, and total salt, while negative correlations were observed with water added and freezing point (p ≤ 0.01). In conclusion, the physical and chemical properties of cow's raw milk are influenced by agro-ecology, season, and the source of milk. Notably, milk adulteration, particularly with the addition of water, was more prevalent among cafeteria owners. Given the absence of established milk quality standards in Ethiopian conditions, it is imperative for the government to introduce quality standard measures, rules, and regulations to effectively control milk quality.
