Abstract

This study was conducted to evaluate feed value of imported hays and examine current situation of species and hay grade. To evaluate the quality of the imported hay, 133 pieces including 9 species of roughage types were collected at the national hay importers, the TMR companies and livestock farms from 2016 to 2018. The quality grades of imported hay were 3~4 and most imported hay were considered to had low. The ADF, Ash, TDN and DDM in feed composition of alfalfa by quality grades presented significant differences(p<0.05). The quality grade on alfalfa was not similar to the actual quality grades calculated through feed composition. The feed composition of grasses by quality degrees presented significant differences in all contents except DM and CP (p<0.05). As the distributed grasses of the unmarked quality grade was low quality and accounted for 49%, it is urgent to present quality standards based on feed composition. As these results, the grades of imported hays were lower than the marked quality grades. Therefore, the imported roughage's(hay) price that considered to only quality grades on the marked imported roughages(hay) package can cause a loss to the livestock farms as economic damage. An institutional arrangement should be established to review the quality grades of imported hay.

본 연구는 수입건초의 품질평가를 통해 사료가치를 평가하고 초종 및 등급별 현황을 파악하고자 수행되었다. 수입건초의 품질 평가를 위하여 2016년부터 2018년까지 전국 건초 수입상, TMR 회사와 축산 농가에서 목건초 9종 133점을 수집하였다. 수입건초의 품질등급이 3~4등급 수준으로 대부분의 수입건초가 사료성분이 낮은 것으로 판단된다. 알팔파의 품질등급별 사료성분은 ADF, Ash, TDN 및 DDM에서 유의적인 차이가 나타났다(p<0.05). 알팔파에 표기된 품질등급이 사료성분을 통해서 산출된 실제 품질 등급과 유사하지 않았다. 화본과목초의 품질등급별 사료성분은 DM 및 CP를 제외한 모든 항목에서 유의적인 차이가 나타났다(p<0.05). 국내에 유통되는 화본과목초 중에서 저품질인 품질등급 미표기가 49%를 차지하고 있으므로 사료성분에 따른 품질기준 제시가 시급하다. 이상으로 수입건초의 사료성분을 검토하였을 때 표시된 품질등급보다 낮은 결과를 나타내었다. 이는 수입건초에 표시된 품질등급만으로 판매가격을 책정하는 것은 축산 농가 및 사료제조사 등에 경제적 손실을 야기한다고 볼 수 있다. 수입건초의 품질등급을 재 검토하는 제도적 장치가 마련되어야 한다.
