Wearing gloves prevents milkers from introducing the bacteria found in the deep fissures of their hands to the udder. Sensitive co-polymer nitrile gloves are recommended for dairymen practicing the "once-under" pre-milking procedure advocated by many veterinarians. The method includes a vigorous rub of each teat after pre-dipping, which is very hard on bare hands. When used during "once-under," gloves protect hands, reduce fatigue, and help to prevent cracked, dry skin.
Thin and strong, co-polymer nitrile has the advantage of losing its "memory" in less than 10 minutes. This reduces stress on the muscles of the hand, and acts like a support stocking, stimulating but not tiring the hands the longer the glove is worn. The low-modulus, hypo-allergenic formula keeps hands feeling cooler and drier, and it is more abrasion and puncture-resistant than vinyl. At the same time, nitrile also has the advantage of disintegrating immediately if a puncture does occur, alerting the operator that the glove must be replaced.
Gloves fit right or left hands and should be worn once, then thrown away.
