Trisha Vet World Premium Replacement Teat Nipple for 2.5L Calf Milk Feeding Bottles. Daily farm nursing and the sharp teeth of growing animals can naturally wear out bottle nipples. Instead of replacing the entire unit, this high-quality spare teat provides a highly economical and dependable solution to restore your 500ml and 1 Liter feeding bottles back to peak efficiency. Masterfully crafted from heavy-duty, food-grade natural rubber, this replacement nipple is 100% non-toxic, chemical-free, and safe for newborn cow calves, buffalo calves, lambs, goat kids, and foals. It is precisely engineered to mimic the shape, flexibility, and feel of a mother cow’s natural udder, reducing weaning stress and encouraging natural nursing behavior. The thick, chew-resistant material effectively withstands aggressive biting from hungry animals. Featuring an integrated flow-control design, it delivers a smooth, steady stream of milk or colostrum, preventing young animals from choking or swallowing excess air, which helps protect against painful colic and bloating. It snaps tightly and securely into the neck caps of standard 0.5L and 1L bottles to ensure zero leakage. Easily washable and completely safe for hot water sterilization. Trust Trisha Vet World for gold-standard, durable dairy farm breeding and livestock care solutions.
