Nutritional evaluation of some agro-industrial byproducts available in Samoa [dry brewers' grains (DBG), cocoa shell (CS), cocoa dust (CD) and desiccated coconut waste meal (DCWM)] available in Samoa was carried out using both the in vivo and in vitro techniques. In the in vivo study 24 Anglo-nubian goats were offered by-products with other feed ingredients to compound four different diets. The goats were randomly allocated to 4 diets on the basis of liveweight (18.7-0.3kg). The ADF content of the byproducts followed a similar trend to NDF. The byproducts have a high content of organic matter (91.0-95.4%). Gross energy (GE) content was higher in DCWM (25.1 MJ/kg DM), closely followed by CD (23.2 MJ/kg DM). Concentrate intake was significantly different (p<0.05) among the goats. Average daily live weight gains were 105, 92, 88 and 97 g/goat/day for DBG, CS, CD and DCWM, respectively. Daily live weight gains were higher (p<0.05) in the goats that received DBG, while the least gain was obtained in the goats that received CS byproduct diet. DM digestibility was significantly higher (p<0.05) in the goats on DBG diet than in the other goats. The least DM digestibility was obtained in the goats that received CD diet (p>0.05). CP digestibility followed a similar pattern to DM digestibility. The digestibility of NDF and ADF was influenced by the nature of the diets. The digestibility of OM and GE were best (p<0.05) in the goats that received DBG, DCWM and CS byproduct diets than in CD. Significant differences (p<0.05) among the byproducts were recorded for net gas production. Potential gas production (a+b) ranged from 7.064 to 42.17 ml. Organic matter digested (OMD) from gas production value at 24 h was higher in DBG (47.6 g/kg DM) and this was followed by DCWM (42.5 g/kg DM). The least OMD was obtained in CD (17.9 g/kg DM). A significant difference (p<0.05) in DM disappearance after 4, 8, 16, 24, 48 and 72 h was recorded. The potential and effective degradability varied significantly (p<0.05) from 85.95-99.6 g/kg DM and from 39.9-65.8%, respectively. The digestibility of the byproducts in both the in vivo and in in vitro techniques demonstrated that they are potential source of feed ingredients for ruminant livestock in Samoa and possibly in the other small Pacific Island countries. On the basis of their potential degradability the byproducts could be ranked in the following order:DCWM>DBG>CD>CS. In conclusion, the results obtained suggest that all the byproducts can contribute to ruminant livestock diets without adverse effects on feed intake, growth rate and apparent nutrient digestibility coefficients.

본 연구는 농식품 부산물을 TMR 원료로 이용하여 사료비 절감 효과와 축산물 품질향상에 도움이 될 수 있도록 그 이용을 활성화하기 위한 농식품 부산물 발생현황조사 및 분석, TMR 이용 현황 및 문제점 조사, 사료이용 시 문제점 및 법률과 제도적 대안을 제시코자 수행하였으며 그 결과는 다음과 같다. 첫째, 폐기물관리법에서 관리되고 있는 유기성폐기물은 폐식용유 10,488톤, 동식물성잔재물 832,493톤, 동물사체 5,740톤, 동물성잔재물 1,171,892톤, 식물성잔재물 2,172,415톤, 왕겨와 미강 12,905톤 등 총 4,205,931톤이었으며 TMR 원료로 이용할 수 있는 식물성 잔재물과 왕겨 그리고 미강이 전체의 51.7%를 차지하였으며 발생지 별로는 전국 상위 10개 지자체에서 76~100% 발생되고 있어 이의 체계적 수급관리시스템이 필요하였다. 둘째, TMR 원료로 사용되는 10대 주요 농식품 부산물은 콩비지, 미강, 깻묵, 맥주박, 주정박, 맥강, 장유박, 감귤박, 버섯부산물 및 기타 식품부산물(빵, 국수, 과자 등)이었다. 셋째, 농가가 농식품 부산물을 이용하는데 가장 큰 애로사항은 농식품 부산물이 폐기물관리법에 의해 폐기물로 관리되고 있어 이를 사용하기 위해서는 재활용신고나 재활용시설설치 등 법률적 의무가 있어 사료이용 활성화를 위해 폐기물 지위 종료제와 같은 제도 개선과 전국적으로 10여 개의 공적 유통센터 설립이 필요한 것으로 사료되었다.
