Sažetak
Balanced feeding of cattle during various production periods, good keeping conditions, avoiding stress, prevention of certain diseases, hormonal status and genetics are factors participating in disease etiology of the locomotion system. In highly productive cows efforts are made to increase energy intake which is often followed by sub clinical acidosis diminishing pH on the pathogenesis of the rumen, liver and the gastrointestinal system impair the chemo-dynamics making predisposition for lameness. The occurrence of acute acidosis accounts for chemo-dynamic insult responsible for serious bad brief episodes of lameness. These episodes can result in predisposition of the rumen for hyperkeratosis, pathogenic infiltration and liver abscesses. Hormonal changes connected with birth and other phases of lactation cycle can influence certain physiological changes that can be a predisposing factor for disturbances in the function of the locomotion system. Unfavorable keeping conditions (hard surfaces, inadequate or poor bedding, short beds etc.) or oversized body weight can be a predisposition for mechanical impairment of leg or hoof structure. Stress (psychological, physical, nutritional, caused by diseases), diseases (mastitis, metritis, infectious diseases, metabolic diseases) and genetics also participate in the etiology of a disorder in the locomotion system functions.
