海鱼鳞粉在哺乳母猪日粮中的应用

Application of marine fish scale meal on the dietary of lactation sows

采用单因子完全随机设计,将18头长太二元哺乳母猪随机分成3个处理组(每处理2头母猪、3次重复),以海鱼鳞粉含量分别为0％、3．5％、7．0％的饲料进行为期28d的饲养试验。结果表明：①不同处理组哺乳母猪产后血清生化指标差异显著(P<0．05)：产后10d,试验组Ⅰ哺乳母猪血清中的AKP和铁浓度显著高于试验组Ⅱ和对照组(P<0．05)；产后20d,试验组Ⅰ哺乳母猪血液中的白蛋白和铁浓度显著低于试验组Ⅱ和对照组(P<0．05)；②各处理组哺乳母猪每日采食量差异不显著(P>0．05)；③各处理组断奶仔猪的料肉比差异不显著(P>0．05)。在哺乳母猪日粮中添加3．5％～7．0％海鱼鳞粉不影响饲料的适口性。

A 28 d feeding trial was conducted to examine the effects of marine fish scale meal （0%, 3.5% and 7.0% respectively） in sow dietaries. Eighteen sows （Landrace×Taihu swine）were randomly allocated into three treatment groups with three replications and two sows in each treatment according to a completely block randomized design. The results showed as followed： ① The serum biochemical parameters of farrowing lactation sows in different groups had significant differences （P〈0.05）： that serum AKP activities and iron concentrations of lactation sows of Treatment Ⅰ on the 10 days after farrowing were significantly higher than those of Treatment Ⅱ and CK; The blood albumen and iron concentration of sows in Treatment Ⅰ on the 20 days after farrowing were significantly lower than those of Treatment Ⅱ and CK （P〈0.05）. ② The daily feed intakes of sows in different treatments showed no significant differences （P〉0.05）. ③ There were no significant differences （P〉0.05） in feed efficiency of weaning piglets in different treatments. 3.5% to 7.0% of marine fish scale meal added to the lactation sows dietaries had no effect on the appetite.
