Somatic cells cheese yield

Vitamin E supplementation has been shown to have positive effects on milk quality in a conventional commercial dairy herd. Milk obtained from cows that received supplemental vitamin E had lower somatic cell counts and plasmin concentrations than corresponding values in milk obtained from control cows. The reduction in plasmin as a result of vitamin E supplementation is very beneficial to the dairy industry because plasmin reduces the cheese-yielding capacity of milk, affects the coagulating properties of milk and its overall ability to withstand processing during cheesemaking (Politis et al., 2004).

Proteolysis of casein may be substantial under certain conditions, such as late lactation and mastitic infections. Under these conditions, the number of somatic cells increases. The most noticeable effect of high somatic cell counts is loss of cheese yield. Everson (1984) identified a loss of 0.045 kg of cheese per 45.36 kg of milk for every 106/ml increase of somatic cell count. Somatic cell counts above 4 x 106/ml were also correlated with enhanced lipolysis and with an increased... 

Mastitis is one of the most common dairy cow diseases. It can cause considerable economic losses to dairy farmers. The losses are incurred from several sources including a decreased milk yield, marked compositional changes in milk that reduce milk quality, treatment and labor costs, and increasing risk of early culling of cows. In addition, milk with a high somatic cell count can have a deleterious effect on cheese...
