A wide range of traditional dairy products with unique visual properties, color and texture are produced in various climatic regions of Iran, which is very important in terms of food security. One of the main reasons for the diversity in traditional dairy products produced in different habitats is the difference in the physicochemical characteristics of milk. Analyzing the effect of the type of pastures and habitats on the physicochemical properties of sheep's milk is a necessary step toward understanding the quality of dairy products and also the management of pastures in the country. In this study, the effect of 8 pasture habitats of the country, including Azerbaijani, Shomal Khorasani, Shargh Zagros, Alborzi, Iran Markazi, Miyani, Khalije Farsi, and Omani, on the physicochemical characteristics of sheep's milk, such as percentage of fat, protein, lactose, solid non-fatty acids, density, freeze point, pH, conductivity, and salts. Results showed that except for density and pH, other physicochemical properties of sheep's milk are affected by the investigated habitats at the 95% probability level. Based on the results, most of the physicochemical properties of sheep's milk in Azerbaijani and Omani habitats had the highest and lowest values in the studied characteristics, respectively. This study is a necessary step towards identifying areas prone to sheep breeding and producing quality dairy products from sheep's milk, as well as better management of pastures and habitats in the country. |
