In addition to deaths from severe infections, the disease can be a cause of lamb mortality from malnourishment or of depressed dissuading weights of lambs. Per-acute, gangrenous (usually due to Staphylococcus aurous), acute, sub-acute, and probably subclinical types occur. Mastitis, or inflammation of the mammary gland, is predominantly caused by bacterial pathogens and occasionally mycotic or algal microbes. Pathologic changes to milk-secreting epithelial cells from inflammation decreases function, ie, milk production. Depending on the pathogen, deceased milk production may continue into further lactations, which reduces productivity and, for beef and other meat-producing animals, potential weight gain for suckling offspring. The organisms most commonly involved are S aureus, coagulase-negative staphylococci, streptococci, Escherichia coli, Mannheimia hemolytic, and Trueperella (formerly Arcanobacterium) pyogenes.The organisms that infect the udder of does are similar to those in cows.Therefore, the study concerns about the occurrence and risk factors that causes mastitis in Ewes (Goats).f the potentialrisk factors has depicted that mastitis was more prevalent indoes with previous mastitis history, increased parity, poorbody conditions, increased milk production, late lactation stage, long teat, and housed goats. Goat mastitis was high compared to camel and other Dairy cattle. In cattle the exotic breed showed the highest (38%) prevalence for mastitis. The study found three risks factors that showed statistical significance at P<0.05 and the three risk factors include: age, parity, and lactation period at a P<0.05. It was also found out that farmers had poor knowledge, practices and attitudes on mastitis control and management. In this study made different analysis and some points out that three (3) sub study area is overall poor practice of dairy farmers in Benadir region. Finally the researchers consult further research to be done in Benadir Region. Keywords: Goats. Mastitis. Clinical. Subclinical. Occurrence. Risk factors.

Introduction Mastitis is a multi-etiological of complex disease, which is defined as inflammation of parenchyma of mammary glands. It is characterized by physical, chemical and, usually, bacteriological changes in milk, and pathological changes in glandular tissues (Radostiset al., 2010). Causes Milk that is trapped in the breast is the main cause of mastitis. Other causes include: A blocked milk duct. If a breast doesn't completely empty at feedings, one of your milk ducts can become clogged. The blockage causes milk to back up, leading to breast infection. Bacteria entering the breast. Bacteria from your skin's surface and baby's mouth can enter the milk ducts through a crack in the skin of your nipple or through a milk duct opening. Stagnant milk in a breast that isn't emptied provides a breeding ground for the bacteria. The occurrence of disease is an outcome of interplay between three major factors: infectious agents, host resistance, and environmental factors. As briefly introduced above, mastitis is a heavy burden for the goat sector worldwide: it is a costly disease due to direct losses (a reduction of output due to mastitis) and expenditure (additional inputs to reduce the level of mastitis), both with negative implications for milk hygiene and quality (Hogeveen,&Huijps, (2011); Coulonet al., 2012). In developed countries, many studies have been conducted. The annual losses per goat from mastitis in the United States of America in 2016 were estimated to be US$ 117.35 per goat per year (Blosser, 2019); two decades later these losses had increased to US$ 185 to $ 200 per goat per year (Costello, 2004). In 2016, annual losses from mastitis in USA were estimated at a total of US$ 1294 billion, and had increased to US$ 2 billion by 2009 (Viguier, 2019). Its negative impact can be a huge constraint on the development of profitable goat enterprises,
