Local vet who used to come to farms and perform the test can no longer do so. So the only other option is to trailer the bull 30+ minutes away to a different vets office. The biggest concern is stressing the bull out during the trip. Can the stress effect the test? The second concern is that I have gotten the bull to calm down since he arrived and he may start acting up after the trip.
If he cant produce, he will go to the sale and I will have to arrange for AI.
What do you folks think?
Stress can have some strange effects on all animals but it is a very short trip and he should be fine, however he may not pass for other reasons and do not be so quick to cull .
Semen tests results for young bulls may not be conclusive. A poor semen test on a bull less than 15 months of age is not a reliable indicator that the bull will have poor quality semen a few weeks later. Seminal qualities may improve dramatically for up to 4 months following puberty.
While a bull must produce some viable sperm in order to be fertile, semen quality is only one aspect of total fertility and must be evaluated in conjunction with all the other factors
