Abstract
[Objective]To enrich forage resources for dairy cows and explore the effects of feeding ensiled sweet sorghum to dairy cows.[Method]The effects of ensiled sweet sorghum on dairy cows were analyzed in terms of milk yield performance and milk quality.[Result]Under the same dry matter intake conditions,the average cumulative milk yield and daily milk yield per cow in the experimental group were 1 049.99 kg and 17.50 kg,respectively,representing increases of 65.79 kg and 1.10 kg compared to the control group.Notably,the average daily cumulative milk yields at 45 d and 60 d showed significant differences(P<0.05)compared to the control group at the same periods.No significant differences were observed in milk fat,milk protein,non-fat solids content,or relative density.[Conclusion]During the trial period,feeding ensiled sweet sorghum contributed to an increase in milk yield,with no significant short-term impact on milk quality.However,long-term effects require further study.Ensiled sweet sorghum,as a high-quality roughage,is suitable for promotion in dairy farming.关键词
