“…An interesting aspect to note is that the chemotactic factors that attract PMN to healthy milk glands are different to those operating in glands with mastitis (Manlongat et al, 1998). Moreover, Bagnicka et al (2011) showed that not only the neutrophils and macrophages but also eosinophils play a crucial defensive role against the pathogenic bacteria.…”

Somatic cell count (SCC) in monitoring udder health has been described in numerous studies as a useful method for the diagnosis of intramammary infection (IMI), and it is considered in standards of quality and hygiene of cow's milk in many countries. However, several authors have questioned the validity of SCC as a reliable IMI diagnosis tool in dairy goats. This review attempts to reflect the importance of different infectious and non-infectious factors that can modify SCC values in goat milk, and must, therefore, be taken into account when using the SCC as a tool in the improvement of udder health and the quality of milk in this species. In dairy goats, some investigations have shown that mammary bacterial infections are a major cause of increased SCC and loss of production. In goats however, the relationship between bacterial infections and SCC values is not as simple as in dairy cattle, since non-infectious factors also have a big impact on SCC. Intrinsic factors are those that depend directly on the animal: time and number of lactation (higher SCC late in lactation and in aged goats), prolificity (higher SCC in multiple births), milking time (higher SCC in evening compared to morning milking) and number of milkings per day, among others. Extrinsic factors include: milking routine (lower SCC in machine than in manual milking), seasonality and food. In addition, milk secretion in goats is mostly apocrine and therefore characterized by the presence of epithelial debris or cytoplasmic particles, which makes the use of DNA specific counters mandatory. All this information is of interest in order to correctly interpret the SCC in goat milk and to establish differential SCC standards.Additional key words: infectious and non-infectious factors; milk quality; mastitis; benchmarking.

“…The results of our earlier study (Bagnicka et al, 2011) showed, that after removing the cytoplasmic particles together with fat, the exfoliated epithelial cells reached up to 67% of total somatic cell count (SCC) in healthy mammary gland. It is strongly evidenced that not only leukocytes but also epithelial cells play a crucial role in the initiation of inflammatory process (Rainard and Riollet, 2003); thus, the high SCC in goat's milk, including exfoliated epithelial cells, might be the reason for the low frequency of clinical mastitis in dairy goats.…”

“…About 20% of samples with somatic cells below 1 × 106 · ml -1 contain bacterial pathogens, including those belonging to the major group. Moreover, many factors can affect the SCC level (Bagnicka et al, 2011).…”

“…Drop in milk constituents like casein, fat and calcium and increase in whey, sodium and chloride in mastitis change technological and organoleptic properties of milk [14,15]. Milk quality is also governed by a low somatic cell count which actually reflects the increase in vascular permeability and escape of leucocytes from blood vessels into the blood.…”

Oxidation and reduction reactions occurring inside the cell must be maintained in the state of equilibrium so that the integrity of cells can be maintained and production of the animals remains at optimum. If there is imbalance between redox reaction, health of the animals gets affected in terms of onset of various reproductive disorders and diseases like mastitis. A number of antioxidants are produced naturally inside the body but under stressful endogenous and exogenous environment, their production is hampered. Thus, supplementation of animals with antioxidants like vitamin C and Vitamin E in feed or parenteral administration is essential to keep the animal healthy to get maximum possible production.
