Growth Performance of Piglets Fed Pharmacological Dosage of the Regular Form and Low Dosage of a New Potentiated Form of Zinc Oxide
One hundred and forty piglets (L × Y × D)were randomly allotted int0 4 groups to determine the effects on piglets receiving either pharmacological dosage of Zno or a low dosage of HiZox.Dietary treatments were: NC,negative control,basal diet containing Zn from the premix; PC,positive control,NC + 3,000 ppm Zn0; Hizl,NC + 3,000 ppru Zn0 (phase 1,1-2 week)/200 ppm HiZox (phase 2,3-6 week); Hiz2,NC + 300 ppm HiZox (phase 1)/200 ppm HiZox (phase 2).All supplemented groups showed better fecal scores than NC.without differences between PC and HiZox groups.At 2 weeks,average daily gains (ADG)were higher in the PC and HiZox groups than in NC.During phase 1,there were numerical improvements in favour of supplemented groups.For the whole period,NC gave the lowest ADG and Hiz1 the highest value,with PC and Hiz2 as intermediate results.The activity of alkaline phosphatase was improved (P<0.05 )in PC,Hiz1,and Hiz2 treatments compared with NC treatment at week 2.The plasma Zn concentration was higher (P < 0.05 )in PC,Hiz1,and Hiz2 treatments than NC treatment at week 2.The fecal Lactobacillus concentration was lower (P<0.05 )in NC than other treatments at 2 week of this trial.Results from this study showed that HiZox was able to replace the regular zinc oxide at a dramatically reduced supplementation level.
