How to fill out DIRECT MICROSCOPIC SOMATIC CELL COUNT

1. Collect a representative milk sample in a clean, sterile container.
2. Ensure the sample is kept at a cool temperature to prevent bacterial growth.
3. Shake the sample gently to homogenize it.
4. Place a drop of the milk sample on a clean microscope slide.
5. Cover the drop with a coverslip carefully to avoid introducing air bubbles.
6. Examine the sample under a microscope using a high-power objective lens.
7. Count the somatic cells visible in a defined number of fields of view.
8. Calculate the average number of somatic cells per milliliter of milk using the total count and the number of fields observed.

Who needs DIRECT MICROSCOPIC SOMATIC CELL COUNT?

1. Dairy farmers monitor milk quality.
2. Milk processors for quality control.
3. Veterinarians assessing udder health.
4. Researchers studying mastitis and milk production.

People Also Ask about

What is the difference between direct and indirect microscopic counts?

The direct methods involve counting cells, whereas the indirect methods depend on the measurement of cell presence or activity without actually counting individual cells. Both direct and indirect methods have advantages and disadvantages for specific applications.

What is the microscopic method of cell counting?

A counting chamber, is a microscope slide that is especially designed to enable cell counting. Hemocytometers and Sedgewick Rafter counting chambers are two types of counting chambers. The hemocytometer has two gridded chambers in its middle, which are covered with a special glass slide when counting.

What is direct microscopic count?

The Direct Microscopic Somatic Cell Count is a modification of the Breed technique in which 0.01 ml of milk sample is spread over a circular 1 cm2 area on a special slide, and is dried, stained, and examined microscopically using the oil-immersion lens.

What is the total direct cell count?

Total Cell Count: Direct/Viable: It's a standard plate count method in which repeated dilutions of a sample determine the number of viable bacteria cells in the given sample. It's used while calculating the number of bacteria in cellular vaccines or milk.

What is a normal somatic cell count?

The SCC is quantified as cells per milliliter. General agreement rests on a reference range of less than 100,000 cells/mL for uninfected cows and greater than 250,000 for cows infected with significant pathogen levels.

What is a good SCC score?

Milk SCC levels above 100,000 mean you are losing money. On average mastitis costs farmers €60/cow/year. It is widely accepted that an individual cow SCC greater than 150,000 cells/ml or an individual heifer SCC greater than 120,000 cells/ml indicates infection in that animal.

What is the direct microscopic somatic cell count?

The Direct Microscopic Somatic Cell Count is a modification of the Breed technique in which 0.01 ml of milk sample is spread over a circular 1 cm2 area on a special slide, and is dried, stained, and examined microscopically using the oil-immersion lens.

What is the direct microscopic cell count?

Microscopic counts – A set volume of a liquid culture is placed onto a microscope slide and one actually counts the number of cells. The advantage of this method is that no incubation time is required to obtain results.
