Abstract
The survey work on pigs were carried out at AICRP, MSP and 30 Sow Teaching Unit of C.V.Sc. pig farms and places of ambulatory classes viz. Kamalpur Veterinary Dispensary, Hajo Veterinary Hospital and Halogaon Veterinary Dispensary from 1st February 2015 to 31st January 2016 to study the incidence of different surgical problems in pigs.
A total of 2,820 numbers of pigs were surveyed and out of which 77 numbers (2.73 %) of pigs were affected with various surgical affections. Age group between 0-3 months 44 (57.14 %) recorded the highest incidence rate and the lowest 1 year and above 6 (7.80 %), male had higher incidence rate 44 (57.14 %) to female 33 (42.86 %). Breed wise incidence of different surgically affected pigs were found to be non-significant as all the animals surveyed were of only cross breeds. On the basis of different surgical affections, umbilical hernia recorded the highest incidence rate 27 (35.07%), while wound and inguinal hernia were the lowest with 5 (6.49%). Summer season recorded the highest incidence 32 (41.56%) and winter the lowest 8 (10.39%). C.V.Sc pig farms recorded higher incidence rate 36 (46.75 %) in comparison to the other three surveyed places.
From the surveyed animals, 12 numbers of pigs affected with umbilical hernia were selected for the present study and were divided into 2 groups irrespective of the age, sex and breed. Group I animals, where the hernial ring was less than 4 cm (approximately 2 fingers breadth) were rendered herniorrhaphy with prolene suture while Group II animals, where the hernial ring was more than 4 cm (approximately 4 fingers breadth) hernioplasty with prolene mesh was carried out.
The clinical parameters viz. pulse rate, respiration rate and rectal temperature and haematological parameters viz. Hb, PCV, TEC, TLC and DLC were recorded on the day before the surgery and on 3rd, 7th and 14th post-operative days to evaluate the efficacy of the surgical procedure. The recorded parameters did not show any significant changes. There was slight increase or decrease in their values during the recorded days which were within the physiological range.
The rendered surgical procedure of herniorrhaphy with polypropylene suture in group I and hernioplasty with polypropylene mesh in group II to the pigs affected with umbilical hernia were found to be effective without any post-operative complications.
Evaluation of healing was done on the 3rd, 7th and 14th post-operative days to record the changes. There were peripheral swelling and exudation during the initial stage of wound healing which were followed by scab formation on the 7th day and complete healing was noticed in both the groups by 14th day. These were normal phenomenon characterized in the course of wound healing. The healing process of wound in both the groups were found to be good with no untoward complications.
