Investigations were carried out to establish the diseases of hooves in breeder bulls raised under the conditions of modern technologies with restricted movements. It was found that hoof diseases were highest in percent (28%) of all non-infectious diseases. Highest was the percent of the typical traumatic ulcer (62 per cent) and of the local and diffuse aseptic and suppurative pododermatitis (34 per cent), whereas the diseases of the hind hooves prevailed--55 per cent as against 45 per cent for the forelimb ones. Higher was the percent of diseases observed in the hooves of the right limbs--63 per cent as against 36 per cent for the cases of diseases observed in the hooves of the left limbs. The higher liveweight of bulls correlated with the frequency at which hoof diseases were recorded. The pigmented hoof horn tissue was found to be more resistant to the effect of external factors and the hoof diseases associated with them. In the months of May, June, and July the cases of diseased hooves were more numerous than in the remaining months of the year due to the lower resistance of the hoof horn over the rainy period.
对在现代技术条件下活动受限的种公牛蹄部疾病进行了调查。结果发现，蹄部疾病在所有非传染性疾病中所占百分比最高（28%）。典型创伤性溃疡的百分比最高（62%），局部和弥漫性无菌性及化脓性蹄皮炎的百分比为34%，而后蹄疾病更为普遍——后蹄疾病占55%，前肢蹄疾病占45%。右肢蹄部观察到疾病的百分比更高——为63%，而左肢蹄部观察到疾病的病例百分比为36%。公牛较高的体重与蹄部疾病记录的频率相关。发现有色素的蹄角质组织对外界因素及其相关蹄部疾病的影响更具抵抗力。由于雨季蹄角质抵抗力较低，5月、6月和7月蹄部患病的病例比一年中的其他月份更多。
