One hundred forty cows that have claw disorder have been used to study the association between lameness and reproductive disorders. Weak estrus owing to ovarian hypoplasia (41.4%) followed by follicular cyst (39.3%) was more frequent than any other disorders. Two hundred ninety-four cows have been used to study the association between lameness and calving to first service and calving to conception intervals depending on lactations, claw disease and floor conditions. And a comparison of number of services per conception between cows with lameness and cows free from lameness was carried out. The calving to first service intervals were significantly increased from average 78 to 102.5 days and calving to conception intervals were significantly increased from 109.6 to 150.6 days in cows with lameness. The calving to first service and calving to conception intervals were not significant different between lactations in cows with lameness. In comparison of calving to first service and calving to conception intervals in cows with lameness depending on claw disease and floor conditions, there was no significant difference. The average number of services per conception was increased from 1.73 to 2.57 in cows with lameness. Service numbers were more frequent during second lactation (3.0 services) but there was no significant difference between lactations in cows with lameness. Therefore, it is likely that the management of lameness is important factor on proper health control of cows and the cows with lameness show decreased fertility.

Proprioceptive neuromusculat facilitation(PNF), scapular patterns are very important for orthopaedic and neurologic patients. It is an essential treatment techniques for motor developmental disorder, CVA, cervical disk, frozen shoulder and pain control of cervical, shoulder girdle and upper extremity. Scapular patterns of PNF has 4 different type of pattern. each of them in combining of movement plane and functional movement. Biomechanically, most of PNF patterns are a concentric contraction with third-claw lever. But the movement pattern have a technique of combination of isotonic that should make a eccentric contraction with second-claw lever.

This study was carried out to investigate the effect of new foot-bath facility and detergent solution (sodium molylbdenate, citrate, potassium nitrate, tataric acid, sodium hypo-cholorite, and zinc sulfate) on claw health in lactating dairy cows. Minimal inhibition concentration (MIC) and minimal bactericidal concentration (MBC) of copper sulphate were 0.31% for E. coli and Bacillus isolated from cows claw. The MIC and MBC of new detergent for E. coli were 1.25% and 5%, respectively, however their respectively values for Bacillus were noticed 0.63% and 2.5%. Both 5E. coli and Bacillus populations in petri-dishes were significantly reduced (more than 95%) with the application of new detergent solution (5% or 16%). Locomotion score (LS 1-5; very good to severely bad) of lactating cows were significantly improved with in 30 days with the use of new detergent solution in foot bath. The LS2 (n=16), LS3 (n=16), and LS4 (n=7) were shown 100%, 43.8%, and 14.3% recovery rate within 30 days with the use of new detergent solution. However, LS5 (n=2) were not recovered to normal claw health and locomotion score within 30 days of new detergent application. Usage of new detergent solution for 60 days in a foot bath have shown 81.3%, 71.4% and 50.0% recovery rate in cows with LS3, LS4 and LS5, respectively. Abnormal claw incidence was reduced from 18.8% to 1.5% in overall herd (n=80) with the use of new detergent solution (16%) in a foot bath for 90 days. In conclusion, usage of 16% of our detergent solution for 60 days in a foot bath can significantly improve the cow claw health and thus mitigate the negative effects of abnormal claw on productivity of cows and dairy farm income.

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.
