The purpose of the experiment was to study the quality of mixed strong aroma distiller's grains and forage rapeseed silage, to determine the optimal addition ratio of strong aroma distiller's grains in forage rapeseed silage. Forage oilseed rape harvested by cutting at the end of flowering period was used as experimental material for silage. Four groups were set up, namely group R (without distillers' grains), group RS-10 (with 10% distillers' grains), group RS-20 (with 20% distillers' grains) and group RS-30 (with 30% distillers' grains). The silage quality was evaluated for 60 d. The results showed that the fermentation quality of forage rapeseed silage was good in all groups, and the sensory evaluation of mixed silage in group RS-10 and group RS-20 was excellent. The CP of distiller's grains supplementation group was significantly higher than that of group R (P<0.05), the content of ADF, Fe and Cu in silage of group RS-20 and group RS-30 were significantly lower than those of group R and group RS-10 (P<0.05), and the pH value of distiller's grains supplementation group was significantly lower than that of group R (P<0.05). The levels of NH3/N and AA in group RS-20 were significantly lower than those in other experimental groups (P<0.05). No butyric acid was detected in silage in all experimental groups. The order of RFV, RFQ and GI2001 was group RS-20 > group RS-30 > group RS-10 > group R. The study indicates that adding strong aroma distiller's grains can improve the silage quality of forage rape, and the fermentation quality of forage rape is better when adding 20% distillers grains.
