Abstract: High performance of goat milk yield ensures genetic potential of breeding work which has been achieved through targeted animal selection, assessment, as well as improving goat nutrition. Our objective was to compare milk composition of four different breeds of goat (Alpine, German White Noble, Thuringia and Latvian Local). During accounting period goats received feed produced in the farm; five goats were randomly selected from each group. Milk samples were analyzed on milk fat and milk proteins concentrations and evaluated on milk cytological and immunological indices. During the trial the highest milk protein content reach German White Noble goats (3.05%), but the highest milk yield reaches Alpine goats – in average 2.24 kg per day. Statistically (p ≤ 0.05) the highest amount of segmentnucleus were found in Thuringia and Alps goat milk (resp., 199 and 187 μL -1), also the highest total amount of monocytes and histocytes were found in Alps goat milk (11 μL -1). Alps and Latvian Local goats milk present increasing of milk active T-, B-, D-cells count and decreasing of O-cells and this indicates a high immune cell functional state. Examining goat milk cytological and immunologic parameters, the goat breeds can be ranked as follows: The Alpine - Latvian Local – Thuringia - German White Noble.
Keywords: goat, milk, milk cells, chemical composition.
