Provided is a livestock nipple pack or the like having high membrane formation force, excellent elasticity, great adhesion relative to nipple surface, no over-curing, little deformation due to drying, the ability to easily peel off after use, and mechanical strength sufficient to withstand impacts and the like that occur after pack installation when a dairy cow or the like lies down to rest or during intense movement particularly a nipple pack or the like in which a water-triturated product forms a gel product having excellent mechanical strength even when the water-triturated product has a high water content and low viscosity with excellent coverage of a livestock nipple elasticity is not readily lost due to drying and the high mechanical strength is well preserved. A livestock nipple pack composition containing a polysaccharide polyelectrolyte, a gelling reaction agent, and a poorly water-soluble solvent as main components a nipple pack coating resin container for coating the livestock nipple pack composition and a gel product of the livestock nipple pack composition, or a livestock composite nipple pack kit configured of a resin curing material for forming the nipple pack coating resin container or either the livestock nipple pack composition or the livestock composite nipple pack kit wherein alginate is selected as the polysaccharide polyelectrolyte the M/G ratio, which is the molar ratio of β-D mannuronic acid to the α-L guluronic acid constituting the alginate, is selected to be in a range of 0.4-0.7 and trehalose is preferably added as a non-reducing sugar.Linvention concerne une partie de tétine de bétail ou analogue, ayant une force de formation de membrane élevée, une excellente élasticité, une grande adhérence à une surface de tétine, pas de séchage excessif, peu de déformation due au séchage, la capacité à être pelée facilement après utilisation, et une résistance mécanique suffisante pour supporter des impacts et analogues qui surviennent après linstall
