The Vink Calfpuller especially helpful in those difficult presentations
This Calfpuller is easy to handle. The rump frame is placed over the cow's rear with
the open end towards the backbone. Then the ropes are attached to both calf's legs
and to lever mechanism in that order. Now gently tension the ropes and it will adopt
the correct position whether the cow is standing up or lying down.
This apparatus consists of two main parts the ratchet pole with lever mechanism and
the rumpframe with pivoting-fork. All parts are constructed in stainless steel.
The unique rump-frame with pivoting-fork encircles the rear of the cow making it
impossible for the frame to slip away from the cow. The pivoting-fork is an original
design feature which permits the herdsman to direct the pulling tension from the
lever mechanism in the ideal way. Downwards for a normal birth and upwards for breech
presentations. This feature gives the Vink Calfpuller its "single-handed" ability;
it needs no extra person to hold it in place to prevent it slipping away during delivery.
The Vink Calfpuller has the following important advantages
* It can not slip out of position.
* Single-handed calving-aid stays where you want it, when you need it.
* It can help to efficiently draw the calf in the correct way for both normal and
* It has a rotating lever system which greatly assists maneuvering the calf during
* The Vink Calfpuller is beautifully designed, robust and is constructed in stainless
steel to ensure long and trouble free service.
During a normal presentation you should draw downwards in the direction of the udder
until the head is born and then in a horizontal line.
When the calf's pelvis threatens to lock in the cow's pelvis you should draw more
in the direction of the udder.
In case of a posterion presentation, the draw should be upwards towards the tail
until the legs are born and then change to a horizontal line.
