Cattle are ruminants, meaning that they have a digestive system that allows them to utilize otherwise undigestible foods by repeatedly regurgitating and rechewing them as "cud." The cud is then reswallowed and further digested by specialized microorganisms that live in the rumen. The calf bottle we offer allows baby calves to get the nutrition that they need when not receiving it from the mother. The gestation period for a cow is nine months. A newborn calf weighs approximately 35-45kg. Cows can live up to be 25 years, so our calf bottle and nipple helps maximize your profit from your herd. Our calf bottle is made if strong and durable polyethylene plastics. Interior walls of bottle are smooth for easy flow and reinforced corners for added strength. Nipples for calf bottle are made from special rubber formula to prolong life and improve pliability.
