Abstract:
This study aimed to investigate the effects of sweet potato leaf extract on production per-formance,systematic and mammary gland oxidative stress status and rumen microbiota of dairy goats fed high concentrate diets.Twenty Guanzhong dairy goats with same parity,similar lactation period(120±15)d and healthy body condition were selected and randomly divided into four groups:low-concentrate(LC),low-concentrate supplemented with 1％sweet potato leaf extract(LCS),high-concentrate(HC)and high-concentrate supplemented with 1％sweet potato leaf ex-tract(HCS).The experimental period was 35 days.The results showed that in the third week,milk yield in the HCS group was significantly higher than that in the LC and LCS groups(P＜0.05).The content of lipopolysaccharide in the rumen fluid of the HC group was significantly higher than that of the other three groups(P＜0.05),the content of malondialdehyde in the serum of the HC group was significantly higher than that of the LCS group(P＜0.05),the content of reactive oxygen species,protein carbonyl,8-hydroxydeoxyguanosine in the milk of the HC group was sig-nificantly higher than that of the LC and LCS groups(P＜0.05),GSH-Px in HCS group was sig-nificantly higher than that in the other three groups(P＜0.05).After the addition of sweet potato leaf extract,there was an increasing trend in the content of Anabaena phylum at the phylum level.In the joint analysis of genera,rumen fluid LPS showed highly significant negative correlation with Succiniclasticum(P＜0.01)and negative correlation with Prevotella(P＜0.05).Valeric acid was negatively correlated with Prevotella(P＜0.05).The pH value was negatively correlated with Treponema(P＜0.05).Butyric acid was positively correlated with Anaeroplasma(P＜0.05).In conclusion,the addition of sweet potato leaf extract to the diet can increase milk production and al-leviate the state of mammary gland oxidative stress,as well as improving rumen microbial diversi-ty of dairy goats.
