title: Plastic debris in the digestive tract of sheep and goats: an increasing environmental contamination in Birjand, Iran.
abstract: A total of 230 goats and 185 sheep were evaluated in this cross-sectional observational study. After emptying the gastrointestinal tract, the size, location, adhesion and obstruction were examined. Twenty seven and half percent of sheep and 24 point 3 % of goats had foreign bodies. Most foreign bodies were plastic materials in sheep and goats. Forty percent of pregnant animals had foreign bodies. Drought and lack of adequate pastures in the past years have been a major cause of the swallowing of foreign objects by sheep and goats.
