Low Colostrum Yield in Dairy Cows During Fall and Winter

Dairy cows produce less colostrum during the fall and winter months, which can have serious consequences for newborn calves. Colostrum is the first milk that cows produce after giving birth, and it is packed with antibodies, nutrients, and growth factors that are essential for the calf's immune system and development.

There are a few reasons why dairy cows produce less colostrum during the fall and winter months. One reason is that the days are shorter during this time of year. Shorter days lead to lower levels of sunlight, which can affect the cow's hormones and metabolism. This can lead to a decrease in colostrum production.

Another reason for the seasonal decline in colostrum production is lower temperatures. When the weather is cold, cows need to expend more energy to stay warm. This can also lead to a decrease in colostrum production.

Finally, changes in diet can also affect colostrum production. During the fall and winter months, cows are typically fed a diet that is lower in energy and protein than the diet they are fed during the spring and summer months. This can also lead to a decrease in colostrum production.

Dairy farmers can take steps to mitigate the effects of the seasonal decline in colostrum production. One way to do this is to bank colostrum from healthy cows during the spring and summer months. Colostrum can be stored in the freezer for up to six months. When a cow calves during the fall or winter, the farmer can thaw and feed the calf the stored colostrum.

Another way to help ensure that calves get the colostrum they need is to provide colostrum supplements. Colostrum supplements are available commercially and can be fed to calves directly or mixed with milk.

By taking these steps, dairy farmers can help ensure that their calves get the colostrum they need to stay healthy and thrive.

Dairy farmers should be aware of the seasonal decline in colostrum production and take steps to mitigate its effects. By banking colostrum and providing colostrum supplements, farmers can help ensure that their calves get the colostrum they need to stay healthy and thrive.
