|Abstract: ||本論文探討不同蛋白質來源及比例對條石鯛幼魚成長及體組成之影響。實驗分為三個部分：（一）飼料中不同蛋白質來源對條石鯛成長、體組成之影響；（二）飼料中以不同含量雞肉粉取代魚粉之蛋白質對條石鯛成長、體組成之影響；（三）飼料中以不同含量水解大豆粉取代魚粉之蛋白質對條石鯛成長、體組成之影響。 實驗一：四種不同蛋白質來源，祕魯魚粉、台灣魚粉、雞肉粉及肉骨粉配製等蛋白45%、等油脂10%之四組實驗飼料，實驗魚隻平均初重10.58 g，實驗為期六週。條石鯛的末重、增重率以投餵台灣魚粉組顯著高於其他三組，祕魯魚粉組和雞肉粉組則無顯著差異，投餵肉骨粉組則顯著低於其他三組。SGR同樣以投餵肉骨粉組顯著低於其他三組，但其他三組皆無顯著差異。FCR介於1.68-3.34，存活率為90-100%。各處理組之魚體肌肉粗蛋白介於83.3-86.0%間，粗油脂介於8.0-10.8%間，魚體肝臟油脂為27.1-51.5%。 實驗二：以雞肉粉分別取代0、20、40、60、80及100%魚粉蛋白，配製等蛋白45%、等油脂10%之六組實驗飼料，實驗魚隻平均初重為2.05 g，實驗為期六週。條石鯛的末重、增重率以投餵飼料取代20及40%魚粉組顯著高於其他各組，取代60及80%魚粉組顯著低於取代20及40%魚粉組而顯著高於控制組及取代100%魚粉組，控制組和取代100%魚粉組間則無顯著差異。SGR在取代20、40及60%魚粉組間無顯著差異且顯著高於控制組及取代100%魚粉組，取代80%魚粉組則顯著低於取代20%魚粉組及顯著高於控制組和取代100%魚粉組，控制組及取代100%魚粉組間無顯著差異且顯著低於其他各組。FCR介於1.70-3.53，存活率為80-100%。各處理組之魚體肌肉粗蛋白介於82.3-83.2%間，粗油脂介於10.8-12.5%間，魚體肝臟油脂隨取代量增加而有上升之趨勢，介於41.4-53.6%間。 實驗三：以水解大豆粉分別取代0、15、30、45及60%的魚粉蛋白，配製等蛋白45%、等油脂9%之五組實驗飼料。實驗魚隻平均初重為2.95 g，實驗為期六週。條石鯛的末重、增重率以投餵飼料中取代15及30%魚粉蛋白組顯著高於其他各組，取代45%魚粉蛋白組顯著低於取代15及30%魚粉蛋白組且顯著高於控制組及取代60%魚粉蛋白組，控制組及取代60%魚粉蛋白組間無顯著差異且顯著低於其他各組。FCR介於2.36-3.36，存活率為97-100%。各處理組之魚體肌肉粗蛋白介於81.6-83.2%間，粗油脂介於10.6-12.3%間，魚體肝臟油脂隨取代量增加而有上升之趨勢，介於25.3-43.5%間。|
This study investigated the effects of different dietary protein sources, poultry meal (PM), meat and bone meal (MBM), Taiwan fish meal (TFM) and soybean protein hydrolysate (SPH) to replace dietary Peruvian fish meal protein on the growth performance and body composition of rock porgy, Oplegnathus fasciatus. Four different protein sources were used to formulate isonitrogenous (45% crude protein)、isolipidic (10% crude lipid) and isoenergetic diets in experiment I. Peruvian fish meal (PFM)、Taiwan fish meal (TFM)、poultry meal (PM) and meat and bone meal (MBM) were used as main dietary protein sources. Each diet was randomly assigned to triplicate tanks with 10 fish per tank. Fish were fed three times daily for six weeks. Rock porgy with 10.58g initial body weight fed diet containing TFM had the highest weight gain (314.73%) and was significantly higher than those fed diets containing other protein sources. Specific growth rate (SGR) and survival ranged from 1.84 to 3.39% day-1 and 90 to 100%, respectively. Crude protein and crude lipid of fish muscle ranged from 83.3 to 86.0% and 8.0 to 10.8%, respectively. The crude lipid of liver of rock porgy fed MBM diet (27.1%) was lower than that of fish fed PFM diet (42.1%)、TFM (38.3%) and PM (51.5%). Six isonitrogenous (crude protein 45%) and isolipidic (crude lipid10%) diets were formulated to replace of 0% (PM0), 20% (PM20), 40% (PM40), 60% (PM60), 80% (PM80) and 100% (PM100) fish meal protein with PM in experiment II. Each diet was randomly assigned to triplicate tanks with 10 rock porgy fish (initial weight 2.05g) per tank. Weight gains of rock porgy fed PM20 (1500.98%) and PM40 (1441.99%) were significantly higher than those of fish fed other treatments. In addition, weight gains of rock porgy fed PM60 (1255.79%) and PM80 (1185.80%) were significantly higher than those of fish fed PM0 (860.31%) and PM100 (742.82%). Fish fed PM0 and PM100 showed no significant differences in weight gain. The SGR of rock porgy fed diets PM20, PM40 and PM60 (6.2-6.6% day-1) showed significantly higher than that of fish fed PM0 and PM100 (5.08-5.37% day-1). Feed conversion ratio (FCR) and survival ranged from 1.70 to 3.53 and 80 to 100%, respectively. Crude protein and crude lipid of fish muscle ranged from 82.3 to 83.2% and 10.8 to 12.5%, respectively. The crude lipid of liver increased with increasing dietary poultry meal. Five isonitrogenous (crude protein 45%) and isolipidic (crude lipid 9%) diets were formulated to replace of 0% (SPH0), 15% (SPH15), 30% (SPH30), 45% (SPH45) and 60% (SPH60) fish meal protein with SPH in experiment III. Each diet was randomly assigned to triplicate tanks with 10 rock porgy fish per tank. Rock porgy with 2.95g initial body weight fed SPH15 and SPH30 had significantly higher weight gain (585.35% and 618.22%) and SGR (4.58% day-1 and 4.69% day-1) than those fed other treatments. There were no significant differences in weight gain (395.01% and 418.05%) and SGR (3.81% day-1 and 3.92% day-1) between fish fed with SPH0 and SPH60. Survival of rock progy ranged from 97 to 100%. Crude protein and crude lipid of fish muscle ranged from 78.4 to 80.2% and 10.6 to 12.3%, respectively. The crude lipid of liver of rock progy increased with increasing SPH.
