In the case of new animals, we suggest an adjustment period of two months. This is mainly for the digestive system to adjust to feeding changes. This phase ensures reduced stress during the synchronization program and after embryos transfer.
It is also important with new animals to be sure of the disease status. We suggest a Brucellosis (BM), Tuberculosis (TB) and Leucosis (EBL) test if possible. Vaccinations against disease, especially those directly affecting fertility should be administered. Treatment against internal and external parasites is also necessary.
It is also good practice to have the possible recipient group examined before the program start to ensure there is no pregnant animals and to check reproductive activity. This is something your local veterinarian can normally take care of.
Make sure the group of recipients is properly identified with an ear tag or brand. This should also be taken care of months before the program starts, as we do not want the extra stress just before or during the program.
Nutrition is extremely important and it is normally easier to start a program with animals in a slightly lower body condition. A month before the embryo transfer, you just supplement or increase their feed. It takes a lot of time to get the animals in proper condition if you start with animals that need to lose weight. It is preferred that animals be in a rising plane of the condition at the time of transfer and therefore you need to take care that animals do not get too fat during the period of increased feed.
Vitamins and minerals are detrimental to reproduction and conception; therefore, it is necessary to ensure the right supplements for your area is provided (injected) 4 to 6 weeks before embryo transfer.
Cattle with temperament problems should get used to handling facilities and being around people prior to the program as this is an indication of stress and stress has an influence on conception. You can achieve this by moving the animals to a came close to the crush, move them through the handling facilities every day or two and feed them after handling. This should reduce stress levels.
