Abstract
The aim of the present study was to investigate the most common surface swellings of the farm animals with special reference to its diagnosis and surgical management of some affection.
The present study was carried out on 397 animals of different species. Their ages ranged from 5 days to 10 years and their weights ranged from 20-500 kg bw. The animals were 174 cattle, 65 buffaloes, 64 sheep, 17 goats, 69 donkeys and 8 horses. They were allocated into 257 females and 140 males.
These animals were examined for swellings on the body surface through history, visual inspection, palpation, centesis and samples of histopathology. Four types of external body swellings were recorded in the present study. These swelling were collected from different animal species and were classified into abscesses (174 cases), hernia (70 cases), bursitis (53 cases) and external neoplasms (100 cases).
In the present work abscesses were recorded in(174 cases (43.8%) out of 397cases. It was detected in different body regions including head and neck, umbilical, abdominal wall, chest, limbs, udder, scrotum and fatty tail. Head and neck appeared to be the most common affected region (59 cases (33.9%)).
In this work, 70 cases of hernia were recorded in different farm animals, which represented about 17.6% of the total cases. They were divided into 49 umbilical hernia (70%) and 21 abdominal hernia (30%). The 18 cases out of 49 umbilical hernia were surgically treated. 10 out of 18 cases were completely recovered while 5 cases were recurrent after removal of the stitches about 20-35 days postoperatively, and 3 cases were complicated with pus formation in the gap formed between the skin and underlying tissue.
Bursitis in this study was recorded in 53 cases, which were divided into olecranon bursitis (25 cases (47.2%), precarpal bursistis (20 cases (37.7%), presternal bursitis (7 cases (13.2%) and calcaneal bursitis (1case (1.9%).
Olecranon bursitis was the most common type of bursitis (47.2%) which was diagnosed only in buffaloes. The total cases of precarpal bursistis were recorded in cattle.
Tumors represented about 25.2 % of the total body swellings which were divided into 60 cases (60%) of papilloma (45 cattle and 15 donkeys), squamous cell carcinoma (7 cattle (7%) and 33 cases (33%)of sarcoids (28 donkeys and 5 horses). The female animals were commonly affected than the males. The animals had more than 2 years old were affected mainly with external neoplasms.
