The objective of this study was to compare the effects of natural clinoptilolite and modified clinoptilolite on growth performance and antioxidant capacity in broiler chicks. Two hundred forty 1-day-old commercial Arbor Acres broilers were randomly distributed into three treatments, each of which had eight replicates. Each replicate contains 10 chicks. Control (CON) group fed with the basal diets, natural clinoptilolite (NCLI) group fed basal diets with 2 % natural clinoptilolite, and modified clinoptilolite (MCLI) group fed basal diets with 2 % modified clinoptilolite for 42 days. The results showed that the 2 % supplementation of natural clinoptilolite and modified clinoptilolite had no adverse effect on growth performance of broilers at 42 days of age. Relative weights of organs were not influenced by dietary treatments at 21 and 42 days. The activity of total nitric oxide synthase was significantly (P < 0.05) decreased in MCLI group than CON group at 21 days of age. At 21 and 42 days, the activities of glutathione peroxidase, catalase, total superoxide dismutase, total antioxidant capacity (T-AOC) were significantly (P < 0.05) increased in NCLI and MCLI groups than the CON group while there was no difference in T-AOC between CON and NCLI groups. The malondialdehyde content was significantly (P < 0.05) decreased in NCLI and MCLI groups than the CON group. It was concluded that the addition of 2 % natural clinoptilolite and modified clinoptilolite to diet can improve antioxidant capacity in broilers, although their effects on growth performance was negligible.
本研究的目的是比较天然斜发沸石和改性斜发沸石对肉仔鸡生长性能和抗氧化能力的影响。将240只1日龄的商品爱拔益加肉仔鸡随机分为三个处理组，每组有8个重复。每个重复包含10只雏鸡。对照组（CON）饲喂基础日粮，天然斜发沸石（NCLI）组饲喂含2%天然斜发沸石的基础日粮，改性斜发沸石（MCLI）组饲喂含2%改性斜发沸石的基础日粮，持续42天。结果表明，添加2%的天然斜发沸石和改性斜发沸石对42日龄肉仔鸡的生长性能没有不良影响。在21日龄和42日龄时，日粮处理对器官相对重量没有影响。在21日龄时，MCLI组总一氧化氮合酶的活性显著（P<0.05）低于CON组。在21日龄和42日龄时，NCLI组和MCLI组谷胱甘肽过氧化物酶、过氧化氢酶、总超氧化物歧化酶的活性以及总抗氧化能力（T-AOC）均显著（P<0.05）高于CON组，而CON组和NCLI组之间的T-AOC没有差异。NCLI组和MCLI组的丙二醛含量显著（P<0.05）低于CON组。得出的结论是，日粮中添加2%的天然斜发沸石和改性斜发沸石可以提高肉仔鸡的抗氧化能力，尽管它们对生长性能的影响可以忽略不计。
