中文摘要:
      用高度不饱和脂肪酸组成和含量不同的四种饲料饲养中国对虾亲虾以研究高度不饱和脂肪酸对中国对虾亲虾产卵及卵质的影响。试验采用脂肪酸组成模式不同的鱼油、亚麻油、玉米油和猪油为脂肪源配制的饲料对产卵前的亲虾进行60天的投喂试验,测定了不同脂肪酸组成的饲料对亲虾产卵量、孵化率和卵脂肪酸组成的影响,并经回归分析结果表明,卵脂肪中的20∶5ω3(EPA)与产卵量、22∶6ω3(DHA)与孵化率有相关关系,表明了EPA、DHA这二种高度不饱和脂肪酸对中国对虾的繁殖力具有特殊的作用,中国对虾亲虾对EPA和DHA的最低需要量为干饲料的1.5%,以保证正常的产卵和卵质。
英文摘要:
      A feeding e xpe riment was conducted to determine the effect of highly unsa tur ated fat ty acids(HUFA)level in broodstock diet on spawning and egg quality of Chinese prawn(Penaeus chinensis ).The effects of feeding four semi-pur ified diets containing dif ferent lipid sources of differ ent f at ty acid profile (anchovy oil , linseed oil , corn oil and pork lard)on fecundity , egg hatchability and egg fat ty acid composit ions of Chinese prawn br oodstock wer e compar ed with a fr esh clam diet in a 60 -day feeding t rial .Good correlation between EPA content of egg lipid and egg product ivity , and be tween DHA content of egg l ipid and egg hatchabil ity wer e observed .It suggests that EPA and DHA take impor tant roles in reproduction of Chinese prawn and that 1 .5 %EPA and DHA content was recommended as a minimum level in broodstock diet .
