  The perinatal¬ period is the most perilous in the life of all animals. Perinatal calf mortality in the first 48 hours of life has been estimated to be between 3 and 10.3%. More than 60% of producers have reported¬ that most of their calf mortality occurs at birth. The main causes of perinatal morbidity and mortality are¬, in descending order of importance¬, combined respiratory and metabolic acidosis¬, parturient trauma, hypoglobulinemia, congenital infections and deficiencies, and omphalophlebitis. Some¬ 90% of calves that die in the perinatal period were alive¬ at the start of calving, and so much of this loss is preventable. Management of the newborn¬ dairy calf is best achieved through implementation of simple protocols that document¬ the correct strategies to be followed at the herd level and the correct procedures to be performed¬ at the individual animal level. These protocols cover management of the prepartum cow, management of calving (monitoring of eutocia and detection and management¬ of dystocia)¬, and newborn calf care. Therefore, it is imperative to provide immediate evaluation and care of newborn calves to ensure calf survival and health and prevent economic losses¬ associated with perinatal¬ mortality.

  Septic arthritis is an important cause of lameness in cattle and calves and delay in treatment, can lead to early culling, a decrease in production, and economic losses in herd. Although responsible for septic arthritis but can also be caused by other microorganisms. This condition occurs when joint space affects by invasion of various microorganisms. Failure of transfer of passive immunity, penetrating wounds, septicemia, and therapeutic or diagnostic interventions are the causes of septic arthritis. Lameness, joint effusion, pain, and fever are the most important of clinical signs of septic arthritis. One or more joints may be affected. Complete physical examination, synovial fluid and blood analysis, and imaging studies techniques are used as diagnostic tools for septic arthritis. Early diagnosis and appropriate treatment of septic arthritis are necessary to improve prognosis. Treatment strategy of septic arthritis includes antimicrobial therapy, anti-inflammatories, and joint lavage. Pathophysiology, diagnosis and treatment of septic arthritis are described in this article. Manuscript profile

  As the anatomical condition of the limbs is extremely important for production performance, animal welfare, as well as economic consequences, it is very important to study the types of limbs malformations in infants and provide corrective measures. A congenital malformation of the animal's limbs is more common in calves, lambs, and foals, involving flexor and extensor tendons in the fetlock and pastern joints. Deformities of the wrist and palmar-carpal joint in the forelimbs are the most common congenital deformities in calves. A non-surgical treatment is performed in cases whose limbs can be opened with the hand, and the ventral part of the fingers is in contact with the ground. The use of surgical treatment is mainly reserved for severe cases of deformity and calves with insufficient correction after splints and casts have failed. Generally, calves with flexion deformity have a good prognosis. Angular deformity of the limb refers to the deviation of the limb outward (valgus) or inward (varus). An Dorso-Palmar (Plantar) position is necessary to examine and measure the deformity's anatomical position. Angular deformities associated with abnormal bone growth plates can be corrected by removing the bone matrix or delaying on growth plate using of fixation through the growth plate. Furthermore, there are two other surgical methods for correcting angular deformity: osteotomy using the closing wedge and the step-wise method. Angular deformities related to imbalances in growth plates have a good prognosis. Secondary angular deformity caused by orthopedic injuries in the opposite limb has a poor prognosis.
