Correlation between phenotypic characteristics of chemical composition and rennet coagulation of sheep milk

Abstract: The aim of the present study was to establish a correlation between phenotypic characteristics of chemical composition, somatic cell count and rennet coagulation of sheep milk during different stages of lactation. The experimental milk samples were taken from Bulgarian autochthonous sheep breed-Local Stara Zagora sheep, newly developed breed-Bulgarian dairy synthetic population (BDSP), and Lacaune sheep breed. From the data obtained about the chemical composition of sheep milk, it was established that Bulgaria… Show more

“…Data on milk components (fat, SNF, lactose, salt, and protein), IPB-1 mastitis score, SSC, and IRT results were analysed by Pearson correlation (p<0.05 and p<0.01) to show the strength of the correlation between the various components of milk, presented in Tables 2 and 3. A fairly high and very significant positive correlation (P<0.01) was found in both the right udder and left udder between levels of SNF-lactose (r=0.79-0.89), SNF-salt (r=0.95-0.97), SNF-protein (r=0.99), lactose-salt (r=0.81-0.87), lactose-protein (r=0.81-0.91), salt-protein (r=0.96-0.98), add water-freezing point In contrast, SCC is an index of udder health that correlates with the level of infection in the mammary gland, whether subclinical, chronic, or acute mastitis (Kalaydzhiev et al 2021). The increase in milk SCC in response to udder infection causes a decrease in milk quality which is characterised by changes in the chemical composition of milk by decreasing casein, lactose, calcium, and increasing sodium, chloride, and serum protein (Pitkälä et al 2004).…”
