About Us / Oberweis Ice Cream and Dairy Store History: Oberweis Dairy milk comes from small to medium sized independent family farmers (producers) who work exclusively for Oberweis Dairy. The average herd size is about 80 cows. Oberweis Dairy pays its producers the highest quality premiums in the area. To become an Oberweis Dairy producer, farmers must meet strict quality guidelines. Individual producer's milk is tested to ensure that our quality criteria are maintained. Dairy cows are never fed hormones or given regularly administered antibiotics. When a cow in the milking herd does get sick, which is certainly normal, our producers take special care to nurse that animal back to health, including the use of antibiotics. During the time a cow is treated with antibiotics, it is removed from the milking herd, and is only returned when its milk no longer tests positive for the presence of antibiotics. \n\nDairy cows are never confined and are fed grains free of animal by-products. Tankers pick up milk daily from our farms and deliver to our dairy plant where the milk is pasteurized, homogenized and bottled in half-gallon glass bottles. When you return your bottles to our store, we then wash, sterilize and re-use our bottles rather than contribute to the problem of overflowing landfills.\n\nThe Oswego Oberweis Dairy Ice Cream and Dairy Store hours are: Sunday through Thursday 10:00 a.m. to 10:00 p.m. Friday through Saturday 10:00 a.m. to 11:00 p.m.
