Milk Quality Characteristics of Native Southern Yellow and South Anatolian Red between Early and Late lactation

South Anatolian Red (SAR) and Native Southern Yellow (NSY) cattle are commonly reared in the southern region of Turkey. Although physical characteristics of these significant races that are under protection are similar, it is determined in various studies that they have different racial characteristics. The goal of this study is to evaluate lactation characteristics of two different breeds in the same region. It is observed that NSY milk has higher dry matter (%), fat (%), protein (%), lactose (%), total saturated and unsaturated fatty acids (g 100g-1 ) ratios than SAR milk. In the study, eight volatiles (indoles, ketones, terpenes, aromatic hydrocarbons, esters, carboxylic acids, aldehydes, alcohols) of the cattle types are researched and analyzed and they are compared during lactation periods. At the end of lactation, esters and carboxylic acids increased in NSY milk, while ketones and aldehydes in SAR milk increased. It is seen that alcohols are the most abundant volatile components found in milk of cattle. On the other hand, it is observed that lactation stages, forage type and botanical diversity affect milk flavor and quality.
