Effect of Potato Vine and Leaf Mixed Silage to Whole Corn Crops on Rumen Fermentation and the Microbe of Fatten Angus Bulls
Abstract
The objective of this study was to evaluate the effects of potato vine and leaf mixed silage (PVS) on rumen fermentation and the microbe in ruminants and to improve the utilization of PVS resources in ruminants through in vitro gas production and feeding trials. The experiment was divided into three groups: PVS1 (50% corn + 50% potato vine and leaf silage), PVS2 (75% potato vine and leaf + 15% rice straw + 10% cornmeal silage) and whole-plant corn silage (CS). The in vitro gas production results showed that there was a significant reduction in PVS groups in the indexes of total gas (p 4 production (p p p p p p p p p > 0.05). In the rumen microbe composition, the PVS diet significantly reduced the abundance of Prevotella (p Lachnospiraceae_XPB1014_group (p Bacteroidales_bacterium_Bact_22 (p 4 emissions and environmental protection.
