Introduction<\/span><\/strong><\/p>\n

Lameness is the second most expensive illness of cattle farms after mastitis, which severely affects the
\neconomic performance of the unit. Each case of lameness causes a decrease in the production of about
\n320 kg of milk in each milking period and can account for a high percentage of the forced removals of
\nthe herd. Lack of copper in cows causes hoof cracking, abscesses and hoof infection. A high level of
\nselenium in animal feed causes lameness and changes in the shape of the hoof. In conditions where the
\npH of the rumen decreases and becomes acidic, the possibility of lameness increases. In general, cows
\nwith lameness show weak signs of estrus, of course, the negative effects can be minimized with the
\ncorrect pick hoof and with appropriate intervals, as well as timely treatment of infectious hoof. In the
\nherds that have problems with cows hoof, after proper pick hoof, in addition to improving reproductive
\nconditions, the amount of cattle feed increases and the amount of cow milk production increases.
\nAn article published in The Journal of Dairy Science reports that lameness causes animals to consume less
\nfeed and may even reduce milk production by up to 6 pounds per day. When the ambient temperature is
\nlower than 77 degrees Fahrenheit, the cows are in good condition. As the temperature and relative
\nhumidity of the environment increases, animals are exposed to higher levels of heat stress. Even at low
\nlevels of heat stress, animals begin to squirm in order to dissipate heat from the body. In such a situation,
\na condition known as “respiratory alkalosis” will occur. In this situation, cows ruminate less and release
\nmore saliva, on the other hand, in order to maintain the proper acid-base balance, cows increase the
\namount of bicarbonate excreted by urine, which may cause acidosis (the cause of lameness). Also, the
\nstanding time of cows in heat stress conditions is longer because in the standing position, the cooling of
\nthe body is done more successfully than in the lying position. But in any case, unfortunately, long periods
\nof standing will lead to the occurrence of hoof problems in livestock and eventually lameness. To prevent
\nsuch problems, most importantly, we should try to minimize heat stress by providing a cool, comfortable,
\nwell-ventilated environment with adequate access to water. Also, by using sufficient amounts of
\npotassium and sodium in the diet, animals will be able to improve the acid-base status by maintaining the
\nbuffering capacity of the rumen and blood. Dr. Charles Guard (Dr. Charles Guard) from Cornell University
\nsays that when cows stand on concrete, “there is a lot of pressure on certain parts of the head of the paw
\nand may lead to vascular lesions such as bleeding or necrosis. When standing, if the hoof is not arranged
\ncorrectly, this local pressure will cause more damage to the hoof.
\nTotal result<\/strong>
\nAs mentioned above, long periods of standing, especially if the bed is made of concrete, have increased
\nthe number of clinical cases of lameness. Adequate nutritional management and correct pick hoof in the
\ndetermined intervals are the key pillars to minimize the incidence of acidosis (lameness agent). Although
\npoor nutrition may contribute to lameness, it is not the only cause.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
