Influences of Marigold Flavonoids on Rumen Fermentation Parameters and Microflora of Simmental Fattening Cattle during High-Temperature Seasons
摘要
Abstract
This experiment was conducted to study the influences of marigold flavonoids on rumen fermentation parameters and microflora of Simmental fattening cattle during high-temperature seasons.Sixty healthy Sim-mental bulls without disease were randomly divided into 4 groups with 15 bulls per group according to the prin-ciple of similar body weight[(518.32±25.59)kg].The control group(M0 group)was fed a total mixed ra-tion(TMR),and the experimental groups were fed the TMR supplemented with 3(M3 group),6(M6 group)and 9 g/(d·head)(M9 group)marigold flavonoids,respectively.The experiment lasted for 67 days,the pre-experimental period lasted for 7 days,and the experimental period lasted for 60 days.The results showed as follows:1)the contents of propionate and total volatile fatty acid(TVFA)in rumen of M6 group were significantly higher than those of M0 group(P＜0.05).Dietary marigold flavonoids had no significant effects on other rumen fermentation parameters(P＞0.05).2)At the family level,the rumen Prevotellaceae relative abundance of M6 group was significantly higher than that of M3 group(P=0.05);at the genus level,the rumen Prevotella relative abundance of M6 group was significantly higher than that of group M3(P＜0.05),the relative abundances of Succiniclasticum and Bifidobacterium in rumen of M6 group were signifi-cantly higher than those of M0 and M9 groups(P≤0.05).In conclusion,dietary marigold flavonoids can in-crease the contents of propionate and TVFA in rumen,improve the rumen microflora,and the supplementation of 6 g/(d·head)marigold flavonoids has the best effect.[Chinese Journal of Animal Nutrition,2025,37(2):1092-1102]关键词
