Macro plastics are defined as plastics that are larger than 20 cm. Plastics that measure between 5-20 cm are referred to as mesoplastics, while those between 1-5 mm are known as large microplastics. Plastics that measure between 1-1000 μm are called small micro plastics, and those that are smaller than 1000 μm are referred to as nano-plastics. Microplastics are particles that result from the degradation of plastic products or are specifically produced in the form of small pieces. They are considered to be less than 5 μm in size. Micro plastics have come to the fore in re-cent years and are pollutants of major concern to the environment. Plastic materials are commonly used on farms, but they can have negative effects on farm animals. Ruminants such as cattle, sheep and goats require cellulolytic micro-organisms for fiber digestion in their diet. The micro biota of the digestive system varies according to dietary habits. The digestive system and other organs can be adversely affected by sudden changes and damage to the micro biota. The ingestion of large plastic materials causes rumen complications such as rumen atony, indigestion and tympani in livestock. Ingested plastic fragments degrade in the digestive tract, increasing the number of small particles likely to be ingested. In a recent study, the presence of low-density micro plastics in sheep feces suggests that animals can ingest micro and macro plastics from their environment and feed. The increase in demand for the consumption of plastics worldwide is increasing the production of plastics. This situation causes the presence of micro plastics to increase rap-idly day by day. Even if the production of plastics decreases, the continuous degradation of plastic waste in the earth will continue the formation of micro plastics and cause environmental pollution. The effects of microplastics in our coun-try should be investigated by conducting detailed studies from the perspective of veterinary medicine.
