PATIL, D. B.BHATIA, MITESH SHASHIKANT2018-06-112018-06-112015http://krishikosh.egranth.ac.in/handle/1/5810051092The breed wise distribution of hoof disorders in affected cattle revealed the highest rate of occurrence in H.F. crossbreds 612/4792 (12.77%)) followed by Gir 94/743 (12.65%) and Kankrej 81/657 (12.32%). Similarly among buffaloes highest breed incidence was recorded in Mehsani (20.92%), followed by Surti (17.92%)), Murrah (14.06%), Non-descript (11.59%) and Jafrabadi (8.29%). The condition of the housing was the main factor in occurrence of hoof problems in cattle and buffalo population. The overall prevalence rate was higher among cattle 553/3949 (14.00%) and buffaloes 123/1073 (11.46%) kept on the kachha floor; and with comfortable housing, the incidence in cattle (234/2243, 10.43%) and buffaloes (42/461, 9.11%) was less. In organised dairy farms, the prevalence rate was higher among cattle 112/871 (12.86%o) and buffaloes 42/461 (9.11%)) tied permanently on pakka floor with no access to exercise and with limited housing area; and followed by cattle 3/47 (6.38%) and buffaloes 0/11 (0%)) maintained on kachha floor with facilities of exercise and comfortable housing. In Panjrapoles the prevalence rate was higher among cattle 416/3167 (13.14%) and buffaloes 98/826 (11.86%) on pakka floor with facilities of exercise. On kaccha floor with uneven surface, the incidence was higher in cattle (159/1127; 14.11%)) and buffalo (28/248; 11.29%). Hoof lesions were observed to be greater in hind limbs (594; 62.20%) with greater involvement of lateral claw (381; 64.14%) than in fore-limbs (154; 42.66%) with more involvement of medial claw (207; 57.34%>). Hoof disorders observed were liigher as the concentrate level in the diet increased. Out of 955 affected animals, 445/1846 (24.10%) were maintained on 80-90 % concentrate diet, 329/2693 (12.22%) on 65-80 % concentrate diet and 181/3207 (5.64%) animals on the 50-65 % concentrate feed. Manual hoof trimming was done in 136 animals with 72 animals in standing position and 32 in recumbence. Twelve vicious animals difficult to restraint required sedation for hoof trimming. Tip Chute was use in 32 animals for hoof trimming. Out of biochemical parameters of blood (Total Proteins, Albumin, Globulin, Calcium, Phosphorus, Magnesium, Sodium, Potassium) and trace minerals from hoof shavings (Zinc, Copper, Manganese, Calcium, Phosphorus), significantly lower levels of Calcium, Magnesium, Phosphorus and Potassium but higher level of Sodium found in serum and significantly lower levels of Zinc, Calcium and Phosphorus but higher levels of Copper and Manganese found in hoof shavings of animals affected by hoof disorders. Successful functional trimming of the hooves in 136 animals facilitated early detection of subclinical laminitic lesions and thus reduced the incidence of hoof lesions. For functional hoof trimming using Tip Chute, less time required along with lower evasion movement score indicating reduced stress than animals trimmed in lateral recumbence on ground without Tip Chute. Use of Tip Chute facilitated proper restraint and comfortable functional hoof trimming with less manpower and time.enVETERINARY SURGERY AND RADIOLOGYA STUDYThesis
