Abstract: 본 발명은 (젖)소의 약물복용용 약병에 관한 것으로서, 보다 상세하게는 연질의 PE 또는 PET 등의 소재로 된 몸체부, PP 소재의 연결부, 그리고 실리콘이나 연질의 고무수지로 만든 (젖)꼭지부, ABS나 강질의 합성수지로 만든 손잡이부로 구성된 가축의 약물복용용 약병에 관한 것이다. 
     본 발명은 약물 또는 영양제 등을 담는 약병(10), (젖)꼭지(20)와 약병(10)을 연결하는 연결캡(30), 약물통의 몸체 목 부분에 부착되는 손잡이고리(40)를 포함하는 것을 특징으로 하는 가축의 약물복용용 약병을 제공한다. 
     일반적으로 (젖)소라 함은 우유나 고기 등의 축산물을 얻기 위하여 인간에 의해 사육되는 동물로써, 최근에는 이러한 (젖)소의 사육이 대량화 되어 인간이 필요로 하는 축산물을 제때 공급되고 있다. 
     이러한 (젖)소는 대체로 일정형태의 축사 내에서 대량으로 사육되고 있으며 이러한 축사는 (젖)소의 배설물과 비위생적인 환경 등으로 인한 각종 질병에 완전 노출되어 있는 것이 사실이다. 
     축산 농가들은 이러한 질병 예방을 위하여 더우면 환기를 시키고 추우면 보온유지, 축사주변의 소독 등 질병 치료나 예방을 위한 무한한 노력을 기울이고 있다. 그러나 이러한 노력에도 불구하고 근본적인 질병 치료나 예방은 되지 않으므로 주사를 놓거나 약물을 복용케 하여 근본적인 치료를 하는 것이 사실이다. 
     그런데 문제는 질병 치료나 예방을 위하여 약물을 복용하는데 마땅한 약병이  없다는 것이다. (젖)소의 질병을 치료하거나 예방을 위해서는 일정량의 약물을 먹여야 하는데 정량표시도 없는 소주병이나 맥주병을 이용함으로써 흘려 버릴 것을 감안하여 정량보다 많은 량을 병에 넣어서 복용케 함으로서 (젖)소의 질병 관리에 어려움이 많은 것이 사실이다. 또한 소주병이나 맥주병은 딱딱하여 (젖)소에게 먹일 때 깨어질 위험성도 있고 입구(아궁이)가 크기 때문에 한꺼번에 많은 량의 약물이 계속적으로 나옴으로 인한 과다 소비 등 비효율적인 면이 많은 것 또한 사실이다. 
     상기한 문제점을 해소하기 위해 안출된 본 발명의 목적은 약을 먹일 때 약물이 나오는 량을 사람 손으로 조절할 수 있도록 PE나 PET 같은 연질의 투명 또는 반투명의 합성수지로 만들되 약물의 양을 확인할 수 있는 눈금이 새겨진 약병과 실리콘이나 연질의 고무수지로 (젖)소의 젖꼭지처럼 만든 (젖)꼭지가 부착된 약병으로써 일정량을 편리하게 먹일 수 있는 (젖)소의 약물복용용 약병을 제공하는 것이다.
