【摘要】 本试验应用正交设计L₉（4）³,研究了中国对虾对配合饵料中脂溶性维生素A、D₃、E、K₃的营养需要。平均体重1.67～2.07g,体长5.20～5.70cm的幼虾,在本试验条件下,经20d饲养试验,结果经统计分析,以平均体重、体长生长比速为考察指标,结果中国对虾对100g配合饵料中脂溶性维生素A、D3、E、K3的营养需要量分别为;维生素A 4.00mg、维生素D₃0.20mg、维生素E 45.00mg、维生素K₃ 3.50mg。更多还原

【Abstract】 Orthogonal design L9(4)3 was employed in the experiments. The results showed nutritional requirements of fat-soluble vitamin A, D3, E and K3 in the compound diet of Penaeus chinensis . Under this experimental condition, Penaeus chinensis of body weight , body length averaged 1. 67 - 2. 07 g , and 5. 20 -5. 70 cm, respectively, after being raised twenty days and through statistics analyses and taking comparative velocity for target in growth of body weight and length, nutritional requirements of fat-soluble vitamins A, D3 ,E and K3 of Penaeus chinensis in every 100 g compound diet are: V-A 4. 00 mg, V-D3 0. 20 mg, V-E 45. 00 mg and V-K3 3. 50 mg, respectively.更多还原
