Relationship between somatic cell count, individual leukocyte populations and milk components in bovine udder quarter milk

Relationship between haptoglobin and serum amyloid A in milk and milk quality

“…Presence in milk of APPs correlated with an elevated SCC ( Table 2 and Table 3), which is in agreement with previous findings related to milk SAA (Lindmark-Månsson et al, 2006;O´Mahony et al, 2006;Åkerstedt et al, 2007) and Hp, respectively (Nielsen et al, 2004;Åkerstedt et al, 2007). SAA in milk, but not Hp, showed significant relationship with lower lactose content.…”

Genetic parameters of somatic cell score and lactose content in goat’s milk

“…Genetic correlations between SCS and yield of fat or protein in cow's milk were 0.10 and 0.15 (Kadarmideen, 2004) or 0.125 and 0.132 (Sender and Krencik, 2000), respectively, and depended on examinated population. Genetic correlations between SCS and fat, protein or lactose contents obtained by Lindmark-Månsson et al (2006) for dairy cattle were different from those obtained in our study (-0.050, 0.393 and -0.774, respectively), but correlation between logSCC and protein content in dairy sheep was closer to our result (0.37 vs 0.54; Baro et al, 1994). The genetic correlation between milk yield and lactose content estimated by Brito et al (2011) in the Brazilian population is different from our result (0.15 vs -0.46).…”

“…Many different indicators of the mammary gland subclinical infection have been proposed, but the SCC is still the easiest and most cost-effective means of recording mammary gland health status also in goat breeding (Rupp et al, 2011). In addition, lactose content can also be used as the indicator of the mammary gland health status (Lindmark-Månsson et al, 2006).…”

Multivariate analysis of lactose content in milk of Holstein and Jersey cows1

“…This could not only improve the quality of milk but also the yield of the finished product. Because lactose, which aids in the osmotic regulation of milk under normal circumstances, is very stable under these conditions, its variation may be helpful in detecting changes in the health of mammary glands (LINDMARK-MÅNSSON et al, 2006;BERGLUND et al, 2007) as well as in nutrition and energy metabolism. Monitoring the lactose levels may help in the quality control and management of farms, helping in the identification of low quality milk (LEITNER et al, 2011) and energy inefficiencies (RIGOUT et al, 2002;QIAO et al, 2005).…”
