摘要:
[Objective]The paper was to study the effects of calcium lignosulfonate(CaLS)on feed processing performance,growth performance,slaughter performance and antioxidant function of cherry valley duck.[Method]A total of 48010-day-old cherry valley ducks were selected and randomly divided into four treatments,10 replicates each treatment and 12 meat ducks each replicate(half male and half female).The ducks in control group were fed with basal diet,and those in experimental groups were fed with the basal diet adding 0.2%,0.4%and 0.6%CaLS,respetively.The trial lasted 28 d.[Result](1)CaLS significantly reduced feed pulverization rate of meat duck(F<0.05),and significantly increased PDI and starch gelatinization degree(F<0.05);adding CaLS had no significant impact on the processing cost(F>0.05),but the granulation electric charge per ton feed could be reduced by 1.06 yuan.(2)CaLS had no significant effect on growth performance,slaughter performance and organ index of meat duck(Q0.05).(3)Compared with the control group,there were no significant differences in serum GSH-Px,T-SOD,T-AOC activities and MDA content of three CaLS groups(F>0.05).[Conclusion]CaLS could improve the processing quality of meat duck feed and reduce the processing cost,hut could not improve the growth performance,slaughter performance and antioxidant function of meat duck.
