Definition: There are many reasons for the decrease in milk yield.  Under normal conditions, following calving, milk yield increases in the first half of the milking period if there is no disruption, and gradually decreases in the second half.  This is normal.

Causes of Occurrence:

1. Sudden feed changes
2. Excessive amount of straw (silage) but low amount of factory feed,
3. Excessive amount of factory feed, but low amount of straw ( silage) feeding,
4. Excessive amounts of grain crushed or additional oilseed meal fed in addition to the factory feed,
5. Decreases in milk yield in parallel with the decrease in feed consumption in hot weather,
6. Insufficient factory feed at the end of weaning, and consequently low milk yield at the beginning of the milking period,
7. Overfeeding during the weaning period, resulting in fattening of the animal and, accordingly, decreases in ketosis and milk yield in the approaching milking period,
8. Sudden milk drops due to not drinking enough water or not having clean water in front of the animal all the time,
9. Feeds such as straw (silage) are moldy and spoiled, factory feeds are fed stale after being stored for a long time,
10. Mastitis (breast disease) s resulting in milk drops,

Type of Treatment and Prevention:

In order to prevent milk drops observed in cows, feeds, especially factory feeds, should be given to animals little by little and within 7-10 days.  During the feeding of animals, feeding programs recommended in different ways for each of our products should be followed.  Clean water should always be available in front of animals.  Deteriorated feeds should never be fed to animals.  A veterinarian should be consulted as soon as possible in cases of milk drop due to microbial diseases.
