Before talking about the real balance, we need to know a little 'anatomy of the bovine foot. The bovine podiatry fact is all based on good knowledge of form and function of the foot of the cows.
We talk about the form.
Each claws, seen from above is covered by a hard structure called wall. The lower part, the one facing the ground, calling instead sole, and is composed of a material is a bit 'softer and more flexible than the hard and rigid wall.
wall and sole, where he founded, taking the name of white line, a real "welding" that combines the two different components dell'unghione and you see very well in cows with dark claws like those of Brune.
We have said that the sole is a bit 'softer wall. Well, this is a very important and we will now see why.
speak of the function.
What are your feet? Of course to walk. But where is that God has willed that his cows had to walk? The cement perhaps? No-no, gentlemen. The feet of the cows were made for walking on soft ground, grass, the sand if you like, but not on concrete or on the grill. The wall of the two claws is tough and strong and with the weight of the animal affects the ground, sinking slightly. This, gentlemen, is called grip.
return to us. The wall, hard, almost sharp, biting, clinging to the natural soil (which is much softer than concrete). The sole provides support and leave a little drink, because it is a bit 'more tender. This increased consumption of the sole to the wall determines the slight indentation of the soil itself. This indentation, in bovine podiatry it can be called "model . The model exactly conducive to the phenomenon of grip, as the wall, outside, slightly protrudes from the sole, as we have said is a bit 'hollow because you consume. It's like if the "sole" of the cow was all around with a crown made to record the hard ground and clings.
Another feature of the model is to keep the soles clean. In fact, the concave shape facilitates drainage of the soil to the rear foot. In this way the sole is good or bad clean, so to speak.
Finally, the model makes sure that the soles are not serious all the weight of the animal, as most of the load is distributed on the wall, especially if the ground is very hard. If the ground is soft but the sink wall and sole rests on the soft and also being a bit 'flexible, it adapts to uneven terrain.
This happens to the cows grazing on all land and natural. On artificial turf is a different story.
How does your foot on the natural terrain
How a tender and green meadow on the feet of the cow? The natural terrain has two very important features: it is soft and abrasive. The compliance
natural terrain makes it very comfortable on the one hand it makes an impact from the wall and provides a safe place, preventing the animal from slipping. On the other hand, this type of soil, deforming under the weight of the cow, acts as a natural shock absorber, just like a nice pair of sneakers.
L ' abrasiveness of natural terrain is due to the presence of pebbles, more or less small. And 'the abrasiveness of the land, wedged between the two claws, uses a different wall and sole and also confers nail its physiological form, characterized by the concavity of the sole, or the "model" that we have already described. The final shape of the nail is the result of the balance between production and consumption of horn. Under natural conditions, ie in free cows to walk on grass, consumption and production of wall and sole are in perfect balance and the nail remains healthy and retains the functional characteristics described.
now very clear that this balance can be easily altered. How? When the cow is prevented from walking, for example, or when the land on which the cow walking differs little from that for which Mother Nature has so split his head. Millions of years of evolution have created
nell'unghione the perfect tool to move a cow in the pasture. Fantastic. So we do?
Take this art and say, well, it feels a bit 'my beautiful concrete now.
E 'well why, dear breeder. If you want your pets to have healthy feet you really really need a good podiatrist, who knows exactly how to work the foot of the cows.
How does your foot in the stall
Unfortunately none of the floors adopted or taken in an intensive rearing of cattle is able to provide the characteristics of the pasture. These floors (mostly hard), in addition to exercising the mechanical stresses different from those offered by the natural soil (mostly soft), are generally also very abrasive, resulting in the breaking of the natural balance between consumption and production of horn, and the loss of the model. In general, in fact, there is no artificial floor in the mixture of soil and pebbles, wedged between the claws, the concave shape of the sole. On artificial surfaces ie the consumption of the base is always perpendicular to the axis of the foot: it consumes the wall, but the sole is allowed to grow. The sole thickens arriving to fill the empty space that would normally be formed on land natural in this way determines the number of diseases that we will see.
Effects of stall flooring on cow foot
Let's see what happens on all types of flooring, from the most comfortable. The
litter is one of the surfaces more like the cows. Just think of the time when animals are moved down the aisle of power: they always grassland, much to the annoyance of the owners. Cows prefer it soft. Yet if the cow walks exclusively on the litter (and is never matched) happens a disaster: the litter box is not at all abrasive, the wall of the nail grows abnormally. Following this growth, the front of the nail works as a lever that raises and lowers the tip dell'unghione your heels, stretching the tendons up to affect aplomb permanently. Also, the sole abnormal growth. Fortunately in this case, the cushioning effect of the litter goes to the help of the foot to prevent this thickening to do too much damage. Even the tires
the cows are very welcome. It 'pretty famous photo of a column of cows that walk on a strip of rubber cement, carefully avoiding the full. Tires on the base lowers slightly, as on natural terrain. On this type of flooring is when the hoof is a well-shaped grip, analoga a quella che avviene sul terreno naturale e che abbiamo già descritto. Inoltre è intuitivo di come la gomma offra un buon effetto ammortizzante. Per rendervi conto in prima persona di quello che dico provate a percorrere a piedi nudi un paio di volte la corsia di alimentazione e poi riprovate a farlo con un paio di buone scarpe da ginnastica. Capite cosa intendo? La gomma è davvero confortevole, tuttavia è per nulla abrasiva, riproponendo lo stesso identico problema di eccessiva crescita della parete, oltre che della suola, abbassamento dei talloni, stiramento dei tendini e alterazione degli appiombi.
Altri problemi delle gomme si manifestano in caso di scarsa pulizia: si forma una patina viscida che rende la superficie pericolosamente scivolosa. In this slippery layer of dirt, in the cooler seasons, with a degree in temperature between day and night, plus the formation of condensation, which leaves the tires wet and aggravates the slippery surface. Finally, if the cows were to decide that the rubber surfaces are more comfortable bunks sdraiasi may choose to stand in the aisles with all the problems associated with toilets.
The concrete is slippery, a little abrasive and certainly not soft. As a result, the claws grow disproportionately in both length and thickness in a bit 'as it does on the litter, although to a lesser extent. Unlike what happens on the litter, however, completely lacking the cushioning effect of this, the accumulation of abnormal horn of the sole act step by step on the "live" as the mills, causing severe bruising. The mechanism is a bit 'like when you enter a pebble in his boot and you end up under foot, with the big difference that you will lift up the boot immediately, as soon as you feel pain, getting rid of the little stone. The cow, unless they are balanced and free of any corneal tissue in excess, we walked on. In this respect, a "live" inflamed nail produces lower quality, stuffed with blood, which easily slot allowing environmental bacteria to penetrate deep into the tissue and produce an abscess, a disease known as "white line disease" or "sobbattitura.
The grid is certainly one of the most unwelcome to the floor and veal, which carefully avoid, if they can. The socket is forced to support more on the edges. In some places, the claws to stand on the grid, has to bear a load of more than ten times what it should stand on a uniform pavement. The grille, as well as being slippery concrete, literally grinds the feet of your cows. Finally, the new floors in issue in contact with concrete slurry substances that affect the structure chimica dell'unghia rendendola meno resistente. Come conseguenza si possono avere problemi di iperconsumo e zoppie gravi che richiedono lo spostamento dell'animale in box infermeria (meglio se con lettiera) anche per tempi prolungati.
In questi casi il pavimento in calcestruzzo andrebbe condizionato prima dell'introduzione delle bovine, come? Bagnandolo con una soluzione di solfato di rame al 5%.
In caso di pavimentazioni piene anche i detriti di lavorazione che rimangono sulla superficie possono accentuare i problemi di iperconsumo. In questo caso consiglio di buttare un po' di letame nelle corsie e di far passare un paio di volte le ruspette in modo da allontanare ogni residuo.
