Abstract

PETROVA, N. and M. TZANKOVA, 1999. SCC of milk from three breeds of buffaloes in Shoumen region. Bulg. J. Agric. Sci., 5: 895-900

A study was carried out to establish the effect of the different somatic cell count (SCC) (less than 500 000; from 500 001 to 1 000 000; and over 1 000 000 cells/ml) on the average daily production and composition of buffalo milk. 47 lactating buffaloes from different dairy breeds (Murrah 10 numbers, Bulgarian Murrah (Back Cross F3 and F4) 31 numbers and Bulgarian Buffalo x Murrah (Back Cross F2) 6 numbers, respectively) from Shoumen region were examined.
Individual milk samples of buffaloes were taken three times in mid-lactation at monthly intervals over a period from May to July 1999.
The number of SCC from 500 001 to 1 000 000 cells/ml reduce the 7% fat corrected milk (7% FCM) and 4.0% protein corrected milk (4% PCM) with l.85% and 3.25% respectively in comparison with SCC less than 500 000 cells/ml.
The number of SCC over 1 000 000 cells/ml reduce the 7% FCM production with 42.80% and 4% PCM with 43,58% in comparison with SCC less than 500 000 cells/ml.
The buffalo milks with SCC less than 500 000 cells/ml were 66.7%, from 500 001 to 1 000 000 17.30% and over than 1 000 000 cells/ml -16.00% for investigated mid-lactation period.
