Abstract:

The study was conducted in Aizawl and Kolasib district of Mizoram, India in 375 numbers of randomly selected pig farms covering 1126 numbers of pigs. The base line survey was conducted using a structured questionnaire. The pigs under study were distributed in different age groups as < 1 months, 1-3 months, 4-6 months, 7-9 months and 10-12 months and above 1 year. The calendar year under study was divided in to four seasons viz. summer, monsoon, retreating monsoon and winter. Different breeds were classified as Yorkshire, Hampshire, Cross breed and Zovawk (indigenous).The disease conditions were observed and diagnosed on the basis of history, clinical signs, clinical, haemato-biochemical and laboratory examination like radiography and bacteriological examination and antibiotic sensitivity test as and when required. After evaluation of the lameness, the animals were treated accordingly and outcomes were evaluated. The rate of incidence of lameness was found to be 7.46 percent with a sex wise incidence of 8.67 percent in males and 5.96 percent in females. Incidence was highest in crossbreed pigs (7.57%) and in the age group of 1-3 months (12.37%). Leg wise affections were highest in foreleg (48.81%) followed by hind leg (38.10%) and both legs (13.10%). Foreleg affections were highest (54.55%) in the age group of 7-9 months and lowest (42.86%) in pigs ˃12 months. Hind leg affections (57.14%) was highest in ˃12 months and lowest (30. 34%) in the age group of 1-3 months. Sixty five percent wound cases were bacteriologically positive with 53.00 percent infected wounds of polymicrobial nature.
