The purchase of a new bull is a significant investment and the greatest risk to this investment is in the first six months.
Webb Black Simmentals recommends clients insure a new bull for six months minimum from the purchase date.
When your new bull/s is delivered ensure he socializes with a small group of animals (not other bulls) in the yards.
Have hay and water available and leave him overnight to settle in.
Do not unload him directly into a paddock, this is when injuries may occur.
The bull/s can now be run with a small group of empty females. Ideally give the cows prostaglandin every two weeks to allow continuous cycling.
We recommend only two new bulls at a time with the empty females for a period of two to four weeks.
Ideally a breeding soundness examination, which includes structural assessment and a service ability test, are recommended particularly for second joining and on older bulls each year.
This allows for the removal of any non-working bulls thus increasing fertility performance within the herd.
The Pfizer STAR program is followed for vaccination covering Vibriovax, Pestiguard and 7 in 1.
Booster vaccinations are recommended in 12 month’s time plus an annual drench four to six weeks before joining.
Do not mix young bulls with older animals at mating. Preferably, your new bull should be mated with a herd (maximum of 40 females) as a single sire or with bulls of similar age.
Allowing your bull to run with younger bulls a few weeks before mating will let them sort out their pecking order.
Keep a close watch on your bulls during mating as the majority of bull fertility issues develop during the joining period.
Also keep a watch for lameness or injuries around the sheath. Early detection and examination by a qualified veterinarian gives a bull a better chance of full recovery.
Replace any suspect bull within the herd as soon as possible to avoid a low conception rate.
Bulls need to be moved to a paddock preferably separating the young bulls from the older ones will minimize injury between joining.
The younger bulls will continue to develop with access to high quality nutrition.
