血红素蛋白和水解珠蛋白对断奶仔猪生长性能和血液指标的影响

Effects of Heme protein and Hydrolyzed globin on blood index and growth performance of weaned piglets

试验旨在通过在教槽料和保育料中添加血红素蛋白和水解珠蛋白,研究其在断奶仔猪上的补血效果和对仔猪生长的影响,评价其应用前景。选用(22±1)日龄(杜×长×大)断奶仔猪432头,随机分为四个组,其中A组为对照组,B、C、D为试验组,每组6个重复,每个重复18头猪。A组为玉米-豆粕型基础日粮,B、C、D组分别在基础日粮的基础上添加0.5 g/kg血红素蛋白、1.0 g/kg血红素蛋白、1.0 g/kg血红素蛋白+10.0 g/kg水解珠蛋白。试验分教槽期(10 d)和保育期(28 d)、过渡期(5 d),共43 d。结果表明,在教槽阶段,不同处理组对仔猪的生长状况和补血无明显影响。在保育阶段,1.0 g/kg血红素蛋白+10.0 g/kg水解珠蛋白组显著提高了仔猪平均日采食量和平均日增重(P<0.05)。添加血红素蛋白可提高血液中血红蛋白的浓度,与对照组76.28 g/l相比,B组和D组血红蛋白浓度显著上升至86.39 g/l和90.14 g/l(P<0.05)。因此日粮中添加血红素蛋白可有效预防保育猪贫血,其和水解珠蛋白的组合使用还可以显著改善仔猪的生长性能,有较好的应用前景。

This study was to investigate the effects of dietary supplementation of Heme protein and Hydrolyzed globin on hematinic effect and growth performance of weaned piglets and evaluate its application prospects.A total of 432(Duroc×Landrace×Yorkshine)weaned piglets at(22±1)day old were randomly divided into 4 groups with 6 replicates in each group and 18 pigs in each replicate.The control group(A)fed a corn-soybean-based basal diet,and treatments B,C and D were respectively supplemented with 0.5 g/kg Heme protein,1.0 g/kg Heme protein,and 1.0 g/kg Heme protein+10.0 g/kg Hydrolyzed globin based on the basal diet.The experiment divide in the stage of creep feed(10 d)and nursey food(28 d),transitional period(5 d),in total 43 d.The results showed that in creep stage,there was no significant difference among the different treatment groups with regard to the blood index and growth performance of piglets in different treatment groups.In the nursery stage,1.0 g/kg Heme protein+10.0 g/kg Hydrolyzed globin significantly increased the ADFI and ADG of piglets(P<0.05).The addition of Heme protein increased the concentration of hemoglobin in the blood,compared with the control group of 76.28 g/l,the hemoglobin concentrations in group B and group D significantly increased to 86.39 g/l and 90.14 g/l(P<0.05).In conclusion,the addition of Heme protein in the dietary can effectively prevent anemia in the nursery pigs,and the combination of Heme protein and Hydrolyzed globin can also significantly improve the growth performance of the piglets.Therefore,these products has a good application prospect.
