| 内容記述 | Recently, complete combined diets for yellow-tails are strongly desired and the nutritional requirement on yellow-tails should be clarified. In order to get the information on the effects of dietaty fat in combined diet on yellow-tails, the feeding experiments were carried out in the concrete ponds. The yellow-tails were fed sufficiently each diet twice a day. The components of the diets used in this experiment are shown in Table 1 On the fish, changes of growth rate, liver weight, blood property and availability of food were examined, and liver and muscle were analysed on the contents of water, crude protein, crude fat and ash by usual method, and on fatty acid composition by gas-liquid chromatography. The following results are obtained ; (1) Between the fish fed corn oil supplied diets and those fed cod liver oil diets, there were differences on the growth in weight and length. Thus, it is established that cod liver oil performs effectively rapid growth on yellow-tails as same as trouts' case. (2) The results of blood examintions on red cell counting, hematocrit value and hemoglobin content showed that the cod liver oil was more suitable for the healthly physiological conditions. (3) Yellow-tails prefered much more the diet supplied with cod liver oil than that with corn oil, and it may be supposed that the differences of growth rate and blood property already observed are resulted from the difference of total protein intake. (4) Food conversion and protein efficiency showed that the diet supplied with 5% cod liver oil was the most efficient among all combined diets used in this experiment. (5) It was proved that the hepatosomatic value altered with the influence of ratio of dietary ingredients. (6) Fat deposition in liver and flesh increased with the increase of supplied fat in the diet. (7) The availability of fat was lower in the case of excess fat content in the diet. (8) The fatty acid compositions of flesh and liver of yellow-tails were depended on characteristics, especially on the amount of supplied fat and combination of dietary ingredients. The oleic acid was remarkably deposited more with combined diet feeding in comparison with raw sand eel. The pattern of fatty acid composition of liver lipid changed more rapidly and remarkably than that of flesh lipid. In this experiment, notable differences were found between the fish fed the diets supplied with corn oil and with cod liver oil, and between the fish fed the combined diets and raw sand eel. It could be supposed that the combination of diet ingredients influences greatly on the metabolism, especially on lipoqenesis, | |||||

| 内容記述 | ハマチにおよぼす油の影響を知るために,陸上水槽で1か月半にわたり,ハマチの飼育試験を行なった。餌料組成は Table 1 に示した。1. コーン油とタラ肝油では成長において,タラ肝油が明らかに優れた効果を有すことがわかった(Fig. 1,Table 2)。2. 血液性状(赤血球数,球量値,血色素濃度)ではタラ肝油摂取魚が正常に近いと思われる値を示した(Fig. 2ー5)。3. 摂餌量はコーン油添加餌料区の方が少なく,ハマチはタラ肝油に嗜好性を持つと考えられ,成長,血液性状に現われる差は,蛋白総摂取量と関連があると推測された。4. 餌料転換効率,蛋白効率からみると本実験範囲内でハマチに最も有効な配合餌料は,5%タラ肝油添加餌料であった(Tables 5-21)。5. 肝量係数は配合餌料の場合,配合比の影響をうけるものと推測された。また鮮魚餌料を与えた魚の肝量係数は,配合餌料を与えたものにくらべて小さな値を示した(Table4)。6. 魚の肝臓筋肉の一般化学成分は餌料の油の影響をうけて変化し,特に油は餌料中の含油量が多いほど体内蓄積量も多くなっている。またコーン油の方が蓄積されやすいといえる(Tables 8,9)。7. 蛋白消化率は餌料中の油の含量が多くなってもあまり変わらないが,油の消化率は含油量が30%になると低下する傾向があった(Table7)。8. 脂肪酸組成は餌料の影響を大きくうける。餌料中の油の種類だけでなく,他の成分との比率の問題,他の成分の種類などがlipogenesis に影響を与えるものと推測された。また,肝臓の脂肪酸組成は餌料の影響を大きくかつ急激にうけるが,筋肉に起こる変化は小さく,また,かんまんであった(Tables 10-18)。 | |||||
