Milk quality in two sheep breedsThe purpose of this investigation was to establish the elementary milkingactivities in sheep as well as to evaluate milk quality in relation to milkingparameters.Material andmethodsMilking time studies and milk quality were carried out on 15 dairy ewesfrom the breed line 05 (13/16 East Friesian sheep, 3/16 Polish Merinos)and 14 meat white head ewes in the experimental farm in Zlotnik (Poland)that belongs to the Agricultural University of Poznan in the year 2000.Ewes of both groups were qualified to milking after they milk-fed theirlambs for two months and had clinically healthy udders. Ewes were milkedmechanically in a 14 Westfalia milking parlor stands with a set of 6 milkingunits. The time from the first udder stimulation to milking unit attachment,milk flow time from each half of the udder, machine stripping, overmilking,total milking time and the time from the first stimulation of the udder tounit detachment were recorded for three consecutive days during morningmilking. On the 75 th day of lactation (mid April) of both breeds of ewes,milk samples were taken from each half of the udder. Milk componentsand somatic cell counts were determined using Milkoscan and Fossomatic90 respectively.For statistical evaluations STATISTICA 97 software was used. The sheepbreed (dairy and meat), lactation (1,2,3 and further) and overmilking ranges(0-100; 101-180 and > 180 sec.) were taken into consideration in this analysisMeans difference between groups were tested for significance Duncan’sTest. Results are presented in tables as means ± SD.Table 1.
