The aim of the thesis was to evaluation of the selected indicators for ewes breed la-caune in grazing rearing. On the basis of donations of milk at regular intervals and the subsequent analysis of the milk was carried out the evaluation of the individual indica-tors. Sheep's milk came from pure-bred ewes breed lacaune (LC). The ewes from which it was collected, milk, have been on the 2. lactation and an only child. The sheep, a breed of lacaune (LC) are kept at the farm top of the Areola. This farm currently has the largest number of pieces of pure-bred sheep breed lacaune in Czech Republic. Carried out with a total of 5 subscriptions from late April to early September in the intervals of 62. day, 90. day, 125. day, 153. day and 195. day of lactation. First was the evaluation of milk yield and the measurement of daily milk yield was carried out by means of mechanical milk rates. Immediately after collection the milk cooled, and transported to the analyses of individual components into specialized labo-ratories. In the stage of lactation in 2015, the average milk yield 1,68 l. Milk from these ewes contained an average of 18,00 % dry matter, fat 7,43 %, 5,16 % protein and lactose 4,67 %. It was furthen evaluated physical and chemical composition of milk, into which encompass the titratable acidy, pH. The average value was at pH 6,59 and the titratable acidy 9,96 SH. And the technological properties of the average length of rennet clotting time 113,2 seconds and rennet curd quality 1,60, holding shape. |
