PETROVA, N. and D. NEDELCHEV, 2002. Production, composition and some properties of sheep milk from East Friesian x 1/4 East Friesian x Awassi dairy population. Bulg. J. Agric. Sci., 8: 295–300
A study was carried out to establish milk production and composition of the 39 lactating milking sheep from dairy breed (East Friesian x 1/4 East Friesian x Awassi).
Individual milk samples of sheep were taken six times during the lactation period at monthly intervals from March – August, 2000.
Investigated East Friesian x 1/4 East Friesian x Awassi dairy breed sheep have 0.604 l /day (at 6.5% fat) and 0.595 l/day (at 5.5% protein) milk production.
Mean values for fat (%), protein (%), lactose (%), total solids (%), solids non fat (%), freezing point (°C) and somatic cell count (ml) of investigated milk were 7.27, 5.93, 4.61, 18.9, 11.6, –0.568 and 1 074 000 respectively.
No statistically significant differences were founded for all investigated parameters between sheep milks of first and second lactation but there were tendency for higher value for somatic cell count of second lactation for all investigated period.
