Abstract
This studies were conducted to investigated the feeding effects of extruded broiler manure(BMERF) mixture and swine manure(SFERF) mixture on laying performance and egg qualify of laying hens. As a experimental feed, broiler manure, corn and tapioca were mixed in 50, 30 and $20\%$ to use for treated extrusion feed(BMERF, Exp. 1) and food waste(FW), swine manure and com were also mixed in 40, 40 and $20\%$ to use it(SFERF, Exp. 2) and implemented during 12 weeks, four replication and 30 chick of each treatment. The nutritional ingredients(protein, energy and calcium contents) of food waste, broiler manure and swine manure had been significantly improved(p<0.05) when handling extrusion. In the Exp. 1, the feed intake was much higher BMERF $40\%$ and BMERF $20\%$ than control and BMERF $10\%(p<0.05)$, the egg production of control, BMERF $10\%$ and BMERF $20\%$ were not significantly difference(p>0.05), but BMERF $40\%$ was significantly lower(p<0.05). The feed efficiency of control and BMERF $10\%$ were not significantly difference(p>0.05), but BMERF $20\%$ and BMERF $40\%$ were significantly lower(p<0.05). York color, White height and Haugh unit did not affected by BMERF additive. In the Exp. 2, the feed intake of control, FW $20\%$, SFERF $10\%$ and SFERF $20\%$ were not significantly difference(p<0.05), but FW $40\%$ and SFERF $40\%$ were significantly higher(p<0.05). The egg production of SFERF $10\%$ and SFERF $20\%$ were not significantly difference(p>0.05) with control, but FW $20\%$, FW $40\%$ and SFERF $40\%$ were significantly lower(p<0.05). The feed efficiency was similar tendency to the egg production, however, the egg weight, york color, white height and haugh unit were not significantly difference among each treatments(p>0.05).
본 시험은 계분 및 돈분의 extrusion 처리가 산란계에 대한 산란성적 및 난질에 미치는 영향을 평가하기 위하여 실시하였다. 실험사료는 계분, 옥수수 및 타피오카를 $50\%,\;30\%$ 및 $20\%$로 혼합하여 extrusion 가공(BMERF)한 사료(실험 1)와 남은 음식물(FW), 돈분 및 옥수수를 $40\%,\;40\%$ 및 $20\%$로 혼합하여 extrusion 가공(SFERF)한 사료(실험 2)를 이용하였다. 실험처리는 실험 1에 4개 처리구(대조구, BMERF $10\%$, BMERF $20\%$ 및 BMERF $40\%$이며, 시험 2에 6개 처리구(대조구, FW $20\%$, W $40\%$, SFERF $10\%$, SFERF $20\%$, SFERF $40\%$)를 두었으며, 12주간 처리 당 4반복 반복당 30수를 공시하여 사양시험을 실시하였다. 남은 음식물, 계분, 돈분의 영양성분은 extrusion 가공에 의하여 단백질, 에너지 및 칼슘 함량이 유의하게(p<0.05)개선 되었다. 실험 1에서 사료섭취량은 대조구와 BMERF $10\%$구에 비하여 BMERF $20\%$ 및 $40\%$구가 높았으며(p<0.05), 산란율은 대조구와 BMERF $10\%$구 및 BMERF $20\%$구는 차이가 없었으나(p>0.05), BMERF $40\%$구는 유의적으로 낮았다(p<0.05). 사료요구율은 대조구와 BMERF $10\%$구는 차이(p>0.05)가 없었으나, BMERF $20\%$구 및 $40\%$구는 효율이 낮은 것으로 나타났다. BMERF 첨가는 난황색, 난백고 및 Haugh unit에 의하여 영향을 미치지 못하였다. 실험 2에서 사료섭취 량은 대조구, FW $20\%$구, SFERF $10\%$구 및 SFERF $20\%$구는 차이가 없었으나(p>0.05), FW $40\%$와 SFERF $40\%$구만이 유의적(p<0.05)으로 높았다. 산란율은 대조구와 SFERF $10\%$구와 SFERF $20\%$구는 차이(p>0.05)가 없었으나, FW $20\%$구, FW $40\%$구 및 SFERF $40\%$구는 유의적(p<0.05)으로 낮았다. 사료효율은 산란율과 비슷한 경향을 보였으며, 난중, 난황색, 난백고 및 Haugh unit는 처리 간 차이(p>0.05)가 없었다.
