Colostrum the cow s first milk is not only important for the health of the neonate newborn calf but has a profound effect on the future performance of the calf all the way through the feeding period. For jerseys an appropriate feeding rate is 10 percent of bodyweight or 3 to 4 quarts.
One third of the calves have received adequate colostrum one third have received a little colostrum and one third have received none.
How long does a calf have to get colostrum. Calves need about two quarts of colostrum or at least five percent of the calf s body weight within four hours of birth ideally within 30 minutes and one gallon within 12 hours. However i am talking about bull calves and i believe some dairies do not feel bull calves are worthy of the colostrum. His excess and low quality colostrum is a great start for a few days.
For commercial operations a tag that has the same number as his mother is a good way to match cows and calves. Colostrum should be harvested clean and fed within two hours of birth. The tricky part is getting the colostrum in quickly.
The immunoglobulins in the colostrum are only able to pass through the intestinal lining of the calf for a short time. Calves that fail to drink on their own within 3 hr of birth should be given colostrum by esophageal feeder. Calves that don t get enough colostrum in the first 12 hours are more likely to have scours and respiratory problems.
Basically we have a 24. Colostrum should be measured to ensure it will deliver adequate antibodies to the calf. We have been able to consistently raise these.
What if the calf doesn t get colostrum in the first 24 hours. Calves should be processed at this time. Generally a calf should receive 5 to 6 per cent of its body weight as colostrum within the first six hours of life and another 5 to 6 per cent of its body weight when the calf is 12 hours old.
She says colostrum deprived calves are 50 to 75 times more likely to die within the first three weeks of life most of them in the first week. Follow up with another feeding eight hours later. A second feeding of 2 3 l of colostrum should be given within the next 8 hr.
Dairies swear the calf received colostrum. About 5 6 weeks before calving immunoglobulins from the cow s serum are concentrated into the colostrum. Joe has several tools available to help his calves stay healthy during the first few weeks of life.
These immunoglobulins are such large molecules that they can t pass through the placenta directly to the fetus. To supplement that he ll use a milk replacer containing plasma plus a serum containing stress pack when his calves typically break with diarrhea around seven to 10 days. Calves that are bottle fed colostrum have a better chance of receiving enough immunoglobulins than calves left to nurse from their mother.
Fpt is usually determined by a test evaluating plasma igg concentration within 24 48 hours after birth. Colostrum weighs about 8 lbs per us gallon or 10 pounds imperial gallon therefore an 80 lb calf would require 4 lbs of colostrums per feeding. Time is important because a newborn calf s digestive tract allows antibodies to pass directly into the blood.
