ABSTRACT
Background:Congenital defects, abnormalities of structures or functions present at birth, maybe as a result ofgenetic or environmental factors or both and in most cases; the exact etiology is not clear but can occur in all animals. These abnormalities are responsible for slowing down of genetic progress and economic loss for the breeders, due to the death of animals.Methods:Available record of cases presented to Aliyu JedoVeterinary Clinic,Sokoto from December 2015 to 2019 was used to investigate congenital malformation in ruminants based on species and sex. Surgery was carried out in all the cases with local anaesthesia (infiltration technique) using lignocaine. Surgical procedures carriedout were rectopexy (atresia ani), gingivectomy (gingival fibromatosis), superficial keratectomy and temporary tarssorhaphy (dermoid cyst), casting and physiotherapy (contracted tendons). Results:A total of 47 congenital malformations; atresia ani 22 (46.8%), gingival fibromatosis 18(38.3%), dermoid cyst 6(12.8%), and contracted tendon 1(2.1%) were reviewed in the study.The ovine species had the highest incidence of cases load recorded 23(48.93%) followed by bovine 17(36.17%) and then caprine species7(14.89%). The incidence of all malformations was higher in males (68.1%) than in females (31.9%). All cases were attempted surgically with success in all the procedures.Conclusions:It can be concluded that male ruminants have the highest prevalence of congenital malformation. Congenital malformations are more frequently seen in ovine and least seen in caprine. Atresia ani appeared to be the most commonly reported cases
ABSTRACT
A atresia anal com fístula retovaginal, é considerada uma afecção congênita rara nos ovinos. Em virtude disso, buscou-se descrever o reparo cirúrgico e cuidados pós-operatórios em uma borrega que apresentava essa afecção. Nesse sentido, uma borrega, sem raça definida, de 25 dias de idade e pesando 7,2kg, apresentou sinais de distensão abdominal e defecação pela vulva. A afecção foi diagnosticada por meio do exame clínico e confirmada radiograficamente, constatando-se atresia anal do tipo III em associação com a fístula.(AU)
Atresia ani associated with rectovaginal fistula is considered a rare congenital anomaly in sheep. Therefore, the surgical correction and post-operative care of a lamb presenting atresia ani with rectovaginal fistula has been detailed in this case report. A 25-days old, mixed breed lamb, weighing 7.2 kg, showing signs of abdominal bloating, and stool passage through the vulva was admitted at our hospital. An atresia ani type III condition associated with rectovaginal fistula was diagnosed by clinical examination and confirmed by radiographic examination.(AU)
