착유우에 있어서 중요한 제한아미노산은 무엇이 있는가? | 즉 적정 요구량 수준에서의 조단백질 공급과 유생산에 필요한 양질의 아미노산 균형이 착유우 단백질 대사에 있어 중요한 요인이라고 할 수 있겠다. 착유우에 있어서 중요한 제한아미노산으로는 메티오닌과 라이신을 들 수 있으며, 많은 연구들이 위 두 가지 제한아미노산의 대사적 역할에 대하여 연구를 수행하였다(Clark et al., 1975; Schwab et al. | |
유우 사료의 단백질 수준은 어디에 영향을 미치는가? | 6%~18.5% 혹은 그 이상이며, 단백질 수준은 유량과 유단백질 생산성에 영향을 미치는 것으로 알려져 있다. 하지만 사료의 단백질 수준만이 유량과 유단백질 생산성을 결정짓는 요인이 될 수 없다는 의견 또한 보고된 바 있다. | |
축산물에서 발생할 수 있는 문제점은? | 축산물은 대표적인 단백질 식품으로 질소에 대한 의존도가 높다. 그리고 가축 체내의 원활한 질소이용이 불충분할 경우, 배출되는 질소량이 증가하고 증가된 질소는 환경오염의 원인이 된다. 이러한 질소의 이용 효율 향상을 통한 생산성 증진에는 다양한 항생물질들이 적용되어 왔다. |
