中药材秸秆替代部分粗饲料对肉羊生长性能和免疫力的影响
Effects of replacing part of roughage with Chinese herbal medicine straw on growth performance and immunity of meat lambs
摘要
Abstract
This study aimed to investigate the effects of different Chinese herbal medicine straws(Astragalus,licorice,stevia,sunflower husk)on the growth performance and immunity of meat lambs,evaluate their potential as forage resources,and provide a reference for the development of new forage products.A total of 120 healthy weaned lambs with similar body weight were randomly divided into five groups,each with three replicates of eight lambs per replicate.Feed(forage and concentrate)was increased every 15 days.Lambs in the control group were fed 30％basal diet+70％corn straw briquettes,while lambs in the experimental groups were fed the 30％basal diet+70％Astragalus straw briquettes,licorice straw briquettes,stevia straw briquettes,or sunflower husk straw briquettes,respectively.The total trial period lasted 60 days,including a 7-day pre-trial period and a 53-day formal trial period.The results showed that the Astragalus straw group exhibited the best weight gain,with an average daily gain of 0.26 kg/(lamb·d),while that of the control group(corn straw)was only 0.22 kg/(lamb·d).The average daily gain of the other treatment groups(licorice,stevia,and sunflower husk)were 0.25,0.25,and 0.24 kg/(lamb·d),respectively,all significantly higher than that of the control group(P<0.05).The serum levels of immunoglobulin G(IgG),immunoglobulin A(IgA),immunoglobulin M(IgM),interleukin-2(IL-2),and interleukin-6(IL-6)in lambs of the Astragalus straw group were significantly higher than those in the other groups(P<0.05).The morbidity and mortality rates in the Astragalus straw group were significantly lower than those in the other groups(P<0.05),and the immune organ indices(thymus and spleen)were significantly higher than those in the other groups(P<0.05).The study indicates that Chinese herbal medicine straws,especially Astragalus straw briquettes,can significantly improve the growth performance and immunity of meat lambs.Such straw resources have high forage value and potential,and are recommended for application in meat lamb production.关键词
