初乳供应—犊牛成功育成的必要步骤
The three main principles for feeding colostrum are: “Fast, sufficient, and top quality”.
If you embrace these principles you will get your calves off to the best possible start and ensure fast, healthy development.
Factor: time
- The absorbability of immunoglobins in the calf's intestine drops very rapidly.
- It is reduced to zero after just a few hours.
- Vitamin A quickly protects the intestinal wall against bacteria colonisation.
Factor: quantity
- The necessary immunoglobin level in the blood serum is only achieved with sufficient quantities of colostrum.
- As a rule of thumb, the ideal quantity of colostrum in the first hour of life is:
approx. 6% of the calf’s liveweight in litres of colostrum (e.g. 45 kg LW = approx. 2.5 litres) - On the first day the ideal quantity is approx. 10% of the liveweight.
- This should be given in a controlled manner with a feeding bottle or a teat bucket.
- We recommend feeding mother’s milk for up to 5 days.
Factor: quality
- Only healthy mother animals produce usable colostrum.
- It is only the first milk that is particularly rich in immunoglobins and vitamin A; active ingredient levels drop very rapidly.
- Older herd cows have a higher immunoglobin level than younger ones, so it is worthwhile building up reserves.
- Colostrum from heifers and bought-in cows should be enhanced with additives.
- Vaccinated cows (long enough before calving) should be given priority as colostrum donors.
