PROBLEM TO BE SOLVED: To provide a new artificial feeding technology in which a back flow to a nasal cavity of feeding milk and coughing caused before the occurrence of respiratory symptoms of a feeding calf are focused on, the shape and size of a feeding teat regarded as the cause are brought more closely to the breast and teat of the mother cow, the swallowing reflex of the calf is promoted smoothly, the back flow to the nasal cavity is prevented more safely to enable health maintenance, and thereby a calf breeding is made possible efficiently.SOLUTION: An artificial feeding cows nipple 1 is formed in a cylindrical wall shape of a predetermined outer diameter D1 in imitation of a teat form of a mother cow, and a predetermined length L1 sufficiently reaching a tongue septum from the lip tip of a calf and not reaching a tongue protuberance from the lip tip of the calf is formed in a barrel wall shape of a predetermined outer diameter D2, and a predetermined length L2 simulating a teat part 2 having a teat hole 21 in the cylindrical wall tip and a breast tip form in the vicinity of a teat root of the mother cow and has a buffer barrel part 3 provided with a wearing opening 31 in the barrel wall base end, integrated so as to bring the teat part 2 into communication with the tip of the barrel wall, and provided with a lip restriction annular wall 32 in the barrel wall tip outer circumference.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】哺乳子牛が、呼吸器症状発生以前に起こす、哺乳用ミルクの鼻腔への逆流と咳込みとに着目し、その原因と目される哺乳用乳首の形状および寸法を、より母牛の乳房と乳頭とに近づけ、子牛の嚥下反射を円滑に促進し、鼻腔への逆流をより安全に防止して健康を維持可能とし、効率的に子牛を育成可能とする新たな人工哺乳技術を提供する。【解決手段】母牛の乳頭形を模した所定外径D1、および子牛の口唇先端から舌中隔に充分に達すると共に、子牛の口唇先端から舌隆起に到達しない所定長さL1の筒壁形状とし、該筒壁先端に乳頭孔21を有する乳頭部2、および、母牛の乳頭根元付近である乳房先端形を模した、所定外径D2、所定長さL2の樽壁形状とし、該樽壁基端に装着口31を設け、該樽壁の先端に、該乳頭部2を連通するよう一体化し、該樽壁先端外周囲に、口唇制限環状壁32を設けた緩衝樽部3を有する人工哺乳牛用乳首1。【選択図】図1
