Abstract

This study was conducted to investigate the effect of organic dietary metabolizable energy (ME) and crude protein (CP) on productivity, meat quality and blood composition of crossbred chicks (hanhyub 3 ho) for different growring periods. Experiments were factorially designed with ME 3,000, 3,100kcal/kg and CP 21, 22, 23% for starter (0-4wks); ME 3,100, 3,150, 3,200kcal/kg and CP 18, 19, 20% for grower (5-8wks); ME 3,100, 3,150, 3,200kcal/kg and CP 15, 16, 17% for finisher (9-10wks). The total number of chicks and replicate of each treatment for starter, grower, finisher were 720, 4; 702, 6; 468, 4, respectively. The diets was mixed with more 90% organic feed ingredients. The productivity were not influence by dietary ME for starting period. Weight gain and feed intake were significantly increased in CP 23% treatment than CP 21, 22% treatment (P<0.05). FCR was improved as dietary CP increased (P<0.05). Weight gain was tended to be increased by decreaing ME content and increasing CP contents for growing period. Feed intake showed no difference among the ME and CP treatment groups. FCR improved significantly in CP 19, 20% compared with CP 18% (P<0.05). Weight gain was not significantly different between ME and CP treatments for finishing period. Feed intake was lower in ME 3,150, 3,200kcal/kg than the ME 3,100 kcal/kg treatment (P<0.05). FCR was higher in ME 3,100kcal/kg than ME 3,150, 3,200kcal/kg treatment (P<0.05). Interaction on productivity was not exited between ME and CP treatment groups for different feeding periods. There was no difference in the total protein, albumin, glucose and triglyceride amount in blood depending on dietary ME and CP contents. Total cholesterol was greatly decreased in ME 3,100kcal/kg than the ME 3,200kcal/kg (P<0.05), but not different between CP treatments. Cooking loss of breast meat was lower in ME 3,150kcal/kg than the ME 3,200kcal/kg (P<0.05). Moisture, shear force and pH were not statistically different among treatments. Protein solubility was increased by increasing ME and CP in diets. The collagen was tended to increase as dietary ME increased. Redness was remarkably higher in ME 3,150kcal/kg than the ME 3,100kcal/kg (P<0.05). Yellowness of meat fed ME 3,150kcal/kg showed significantly lower than other treatments (P<0.05). Therefore, the optium ME and CP to improve the productivity for each period were 3,000kcal/kg, 23%; 3,100kcal/kg, 19%; 3,150kcal/kg, CP 16%, repectively.

본 연구는 토종닭(한협 3호)에 사육 기간별 대사에너지 및 단백질 수준이 다른 유기사료의 급여가 생산성, 계육품질, 혈액성상에 미치는 영향을 구명하기 위하여 수행하였다. 실험설계는 전기, 중기, 후기에 각각 $2{\times}3$(ME 3,000, 3,100kcal/kg; CP 21, 22, 23%), $3{\times}3$(ME 3,100, 3,150, 3,200kcal/kg; CP 18, 19, 20%), $3{\times}3$(ME 3,100, 3,150, 3,200kcal/kg; CP 15, 16, 17%) 요인실험이며 처리구당 총 공시수 및 반복은 전기에 720수, 4반복, 중기에 702수, 6반복, 후기에 468수, 4반복으로 하였다. 사육 전기 4주간에 사료에너지 수준은 생산성에 영향을 미치지 않았지만 CP는 23% 처리구에서 증체량, 사료섭취량이 21, 22% 처리구보다 매우 증가하였다(P<0.05). 사료요구율은 사료내 단백질 수준이 높을수록 개선되었다(P<0.05). 사육 중기에 증체량은 사료내 에너지가 낮을수록, 단백질은 높을수록 증가하는 경향을 나타내었다. 사료내 에너지 및 단백질 수준은 사료섭취량에 영향을 미치지 않았다. 사료에너지 수준에 따른 사료요구율은 CP 19, 20% 처리구에서 18% 처리구보다 개선되었다(P<0.05). 사육 후기 증체량은 사료에너지와 단백질 수준에 따른 차이가 없었다. 사료섭취량은 ME 3,150, 3,200kcal/kg 처리구에서 ME 3,100 kcal/kg보다 감소하였지만 사료요구율은 개선되었다(P<0.05). 혈중 총단백질, 알부민, 글루코오스, 중성지방은 에너지 및 단백질수준에 따른 차이가 없었다. 혈중 총콜레스테롤은 ME 3,100kcal/kg 처리구에서 ME 3,200kcal/kg 처리구보다 감소하였고 CP 처리구간 차이는 없었다(P<0.05). 가열감량은 ME 3,150kcal/kg 처리구에서 ME 3,200kcal/kg 처리구보다 감소하였다(P<0.05). 수분함량, 전단력, pH은 ME, CP 처리구간 차이를 나타내지 않았다. 단백질용해성은 에너지 및 단백질수준이 높을수록 증가하였다. 계육내 콜라겐(collagen) 함량은 에너지 수준이 높을수록 증가하는 경향이 있다. 계육의 백색도는 사료내 에너지수준이 감소할수록, 단백질수준은 증가할수록 개선되는 경향이 있었다. 적색도는 ME 3,150kcal/kg 처리구에서 ME 3,100kcal/kg 보다 증가하였다(P<0.05). 황색도는 ME 3,100, 3,200kcal/kg 처리구에서 낮아졌으며, CP 15, 17% 처리구에서 CP 16% 처리구보다 매우 낮아졌다(P<0.05). 따라서, 사육기간별 적정 유기사료내 에너지 및 단백질수준은 사육전기 4주간에 ME 3,000kcal/kg, CP 23%, 중기 4주간에 ME 3,100kcal/kg, CP 19%, 후기 2주간에 ME 3,150kcal/kg, CP 16% 급여가 생산성 개선에 적합하였다.
