Description

Method and system for treatment of larger animals such as down cows.
The present invention relates to a method for treatment of larger animals such as down cows, that is cows which due to 5 physiological disorder are not able to raise themselves.
The cattle disease "milk-fever" may cause paralysations of the hind legs of cows and under those conditions the cow will naturally be laying down and the cow is not able to 0 raise itself. Said paralysations may also be caused by birth-problems and to prevent the paralysations from perma¬ nent damaging the cow it is important that some physiologi¬ cal treatment of the affected hind part of the cow is star¬ ted as soon as possible. 5
Furthermore, down cows may be the result of the cow slide on a smooth and moist surface or even of the cow do the split and strain the muscles of the hind thigh. However, the necessary treatment is rather difficult to carry out 0 whem the cow is lying down and in particular if the cow is lying in the field or in the bush.
Previously use was made of a socalled hip-clamp which was placed around the hips of the cow for raising her by means 5 of a suiteable hoisting. However, the use of hip-clamps has been forbidden because the cow suffered terribly by inju¬ ring the hip muscles. Alternatively, use was made of a spe¬ cial sling which was places around the hind part of the cow, but in practice it is certainly difficult to get such 0 a sling on a down cow.
Consequently, such down cows have hitherto caused financial troubles for farmers because in most cases is has been ne¬ cessary to put down the cow in the field which normally 5 means that is it not even allowed to utilize the meat. On the other hand cows and heifers are often very valuable breeding animals and in practice most farmers are ready to offer relative large amount of money in order to save the cow or heifer.
The invention has for its purpose to provide a method for treatment down cows and by means of which it by simple pro¬ visions is possible to save down cows by getting them back on their legs again.
The method according to the invention is destinctive in that a towing mat preferably made from rubber is placed next to the down cow, that the cow is rolled onto the mat, that a treatment tank of which doors at opposite ends are removed is positioned in front of the cow in such manner that a ramp of the tank is placed nearest the cow's head, that the mat with the cow on it by means of a tractor or a truck is pulled into the treatment tank, that both end doors are replaced to make a water-tight, sealed tank, and that preferable warm water is filled into the treatment tank for assisting the cow in raising herself.
By simple provisions is hereby obtained a method for treat¬ ment of down cows and by which it in most cases may be pos- sible to save down cows. The lifting ability of the water in the treatment tank relieves the legs of the down cow from the full weight of the body and in most cases it is sufficient to assist the cow in getting on its own legs again. A halter is put around the cow's head to assist the cow in keeping the head above the water while filling the treatment tank. The very free straightening out of the legs counts as a real treatment; but of course it would be pos¬ sible to further manipulate the legs or the hind part of the cow. Preferably, the method according to the invention is car ried out by means of a treatment tank which is build-up o a trailer in such a manner that the treatment tank may as¬ sume either a transport position where the tank is lifte free from the ground or a working position where the tank is supported on the ground.
And according to the invention it may be advantageously that the treatment tank is moved to a location accessible to warm water and where the ground is level and soft before filling in warm water into the treatmant tank.
When the cow after the treatment - by herself - exits the treatment tank it is important that the cow has extremely good footing so that she does not slip or do the splits.
The invention also relates to a system for use by treatment of larger animals such as down cows, that is cows which due to physiological disorder are not able to raise themselves, and comprising a drag mat being adapted to be placed on the ground next to a down cow for rolling the cow onto the drag mat, and a ramp adapted to be placed in front of the cow's head between the ground surface and a narrow end edge of a plane bottom surface of a treatment tank which at opposite narrow ends is provided with door openings in which loose doors plate members may be mounted for water-tight sealing the treatment tank when the cow on the drag mat is pulled into the treatment tank which preferably is provided with valve means for discharging water from the treatment tank.
Preferably the system according to the invention further comprises a water heater (boiler) unit which preferably is build-up on a trailer and being adapted to supply warm wa¬ ter to the treatment tank. Appropriately, the system according to the invention is such provided that the treatment tank is provided with mu¬ tually parallel and upright side walls which at opposite end edges being provided with sealing means, and that said loose door plate members at opposite end edges also being provided with sealing means.
In order to make the system mobile and easy to operate it may advantageously be such provided that the treatment tank being build-up on a trailer in such a manner that the treatment tank may assume either a transport position in which the tank is lifted free from the ground or a working position in which the tank is supported on the ground.
And in a preferred embodiment the system according to in¬ vention is such provided that supporting wheels of the treatment tank trailer are mounted on girders forming part of a trailer draught system in such a manner that the wheels are positioned in some distance in front of pivot points for rearmost ends of said girders the front ends of which being connected by a cross bar with a central connec¬ tion bar adapted to be coupled to a tractor or a truck, that fixing means being provided between said girders and the tank sides in order to secure the girders either in said working position where the treatment tank is supported on the ground or in said transport position where the treatment tank is lifted free from the ground, and that the pivot axises for executing the lifting momemtum by lowering the trailer draught system is formed by the axises of the supporting wheels.
Furthermore the system according to invention is such pro¬ vided that locking means being provided at both ends of the treatment tank and at both sides thereof said locking means consist of a principally vertical latch bar which at one side has a centrally projecting latch with an open slot adapted to receive a tighten bolt a basic end part of which being pivotally secured at an outer side of the tank, while a threaded free end of the bolt is provided with a locking handle by means of which the latch bar may be rotated about its own axis, said latch bar at an opposite side comprise a number of projecting lacthes being adapted to be inserted in open ends of outer transverse profile members of the door plate member so that said sealing means at the respec¬ tive side edges of the door plate member by means of the tightening handle may be forced against said sealing means at the respective end edges of the treatmant tank.
Preberably, the system according also comprises a wheel- supported cattle stretcher adapted to be used when fetching a down cow out from a cattle shed.
In the following the invention is described in more detail with reference to the drawing, in which:-
Fig. 1 shows a right side elevation of an embodiment of a wheel-supported treatment tank according to the in¬ vention.

Fig. 13 shows an embodiment of a stretcher for fetching down cows out from cattle shed, and
Fig. 14 shows an embodiment of wheel-supported boiler tank for producing warm water on location.
A treatment tank 2 shown in Fig. 1 is mounted on a trailer chassis 4 in such a manner that the treatment tank 2 may either be positioned in a transport position - shown in full lines - or in a working position supported on the ground shown in dotted lines.
First of all, the treatment tank 2 in the transport posi¬ tion is moved to a location near the down cow to be trea¬ ted. The treatment tank 2 is pivotally mounted between rearmost ends 6 of carrying beams 8 of the trailer chassis 4 in such a manner that a pulling tongue arm system 10 of the trailer chassis 4 may be used as a lever supported by means of wheels 14 on the ground. After removal of locking pins from locking holes 16 the pulling tongue arm system 10 is swung rear-/upwards for lowering the treatment tank 2 to the ground supported working position in which the carrying beams 8 and the pulling tongue arm system 10 is again secu¬ red by insertion the locking pins in locking holes 18. Pre- ferably, the treatment tank should now be placed in the ground-supported working position with the rear end near to the head of the down cow.
Door plate members 20 (Fig. 5) are removed from both ends of the treatment tank 2, the open cross section of which is shown in Fig. 3. The treatment tank 2 has a smooth bottom surface 22 and smooth inner wall surfaces 24. In order to provide engagement edge flanges 26 for the door plate mem- bers 20 at both ends of the treatment tank 2 flat U-shaped frame members 28 - shown in Fig. 4 - are welded to both end surfaces of the treatment tank 2 of which the bottom surfa¬ ce 22 and inner wall surfaces 24 are indicated with dot- and-dash lines in Fig. 4.
A ramp 30 (Figs. 9 and 10) which may have a storage posi¬ tion on the left side of the treatment tank 2 (Fig. 2) is placed at the open rear end of the bottom surface 22 of the treatment tamk 2 with a bent connection flange plate 32 po- sitioned over the lower engagement edge flange 26.
A drag mat 34 (Fig. 12) which preferably is made from strong rubber material is placed next to the down cow. The down cow is rolled onto the rubber drag mat 34. With a tractor or truck the drag mat 34 (with the down cow on it) is pulled into the treatment tank 2 via the ramp 30 and the open rear end of the tratment tank 2.
The ramp 30 is removed and both the door plate members 20 are replaced in order to make a water-tight sealed treat¬ ment tank 2. The side edges 36 and the lower edge 38 of the door plate members 20 are provided with sealing strip mem¬ bers 40 the croos section of which is shown in Fig. 11. The sealing strip member 40 comprises a connection part 42 adapted to be mounted on the edges of the door plate mem¬ bers 20 in such a manner that a closed tube-shaped profile part 44 of the sealing strip member 42 is placed along th edges of the outer surfaces of the door plate members 20.
The door plate member 20 is provided with upper bracke plate members 46 by means of which the door plate member 20 may supported on the upper side edges of the treatment tank 20.
The door plate member 20 is on the outside surface provided with three horizontally placed parallel squared tube mem¬ bers 48 the opposite open ends of which being cut inclined for easy receiving outer free end of locking latches 50 projecting from a vertical mounted door seal latch bar 52 (Figs. 6 and 7) which opposite the locking latches 50 has a centrally projecting clamp latch 54 provided with a central slot 56 adapted to receive a clamping bolt 58 the basic end of which being journaled between brackets 59 (Fig. 8) secu¬ red to outside corners of the treatment tank 2. Outside the clamping latch 54 the clamping bolt 58 cooperates with a door lock handle 60 (Fig. 8) by means of which the door seal latch bar 52 may be rotated around its vertical axis for pulling the door plate members 20 in order to establish a water-tight sealing engagement between said tube-shaped part 44 of the sealing strip members 40 and the engagement flanges 26 of the treatment tank 2. The door plate members 20 have vertcal handles 49 between the two upper tube mem¬ bers 48.
Before filling the treatment tank 2 with warm water with a temperature of some 38 - 40 °C it may be neccesary to move the treatment tank 2 with the down cow in it to a location accessible to warm water and where the ground is levet and soft - it is rather inportant that the cow has extremely good footing when exiting the tratment ta k 2 so she does not slip or do the splits. If necessary to move the treat¬ ment tank 2 with the down cow in it the trailer tongue arm system 10 is again lowered in order to lift the treatment tank 2 up to its transport position and of course the lock¬ ing pins are again inserted into the locking holes 16 for securing the treatment tank 2.
Alternatively, if the treatment has to take place at a lo¬ cation without supply of warm water a special water boiler mounted on a separate trailer (Fig. 14) may be used. A hal¬ ter Wis put around the cow's head to assist her in keeping her head above water while filling the tank 2. When ready the treatment tank 2 is filled with warm water (up to about the cow's hip) . The warm water will help the muscles and stimulate the blood circulation. The cow has to stay in the warm water for 6-7 hours.
After the treatment the water may slowly be drained out from the treatment tank 2 so the cow can get use to her normal weight again through an outlet valve 62 (Fig. 1) just over the bottom surface 22 of the treatment tank 2. It may be advantageously to let the cow stay in the empty treatment tank 2 for about an hour before again removing the door plate members 20 and let the cow exit the treat¬ ment tank 2 by herself.
If the cow goes down with the water the draining is finish¬ ed and the cow has to stay inside the treatment tank for another eight hours. Feed the cow in the treatment tank 2 before filling the tank again with warm water.
Before allowing the cow to exit the tretment tank 2 remove the back door plate member 20 and milk her, if necessary. Replace back door plate member 20 when finished milking.
The cow's exit must be very slow and controlled. Remove the front door plate member 20 and let her slowly walk out. For a more controlled exit special rails are recommended at each side of the treatment tank 2. If the cow goes dow again she should allowe to rest a while before she is agai put back into the treatment tank 2 for another treatment.
If the cow goes down inside the cattle shed a special stretcher (Fig 13) may be used to fecth her out in the open before beginning the treatment.
