The data was collected from records found in the firm, wholesalers, distributers, veterinary office, and animal farms. Also, the research questioner was used if the records not found or the data not accurate. The data obtained includes, type of drugs (We take 10 samples places of the drug) and we collect the information about each drug that includes (Price of drugs in the firms, Price of the drugs at different periods of the transportation, Price of the drugs at the period in which the farmers purchase it).
Our results concluded that, the marketing margin constitutes about 40 – 45 % from the price of the drug at the factory level and constitutes about 29 - 30 % from the price of the drug at the farm level. The main factors affecting the marketing margin is the values that added to the prices of the drugs due to costs of transportation, storage, payements, advertising, costs of veterinary office and at the farm, for improving and decreasing the price of the drugs we must decrease the level of marketing margin. The decreasing of marketing margin is done through improving and save the transportation methods, storage and warehousing, veterinary office and the methods of transportation to farm and to veterinary office.
