The effect of adding wheat straw and Lactobacillus buchneri on the quality of fodder beet silage in polyethylene bags

This study was conducted to investigate the effect of adding 0, 10 and 15% levels of wheat straw and the use or non-use of Lactobacillus buchneri microbial additive on the quality of fodder beet silage (FBS) in polyethylene bags in a 3×2 factorial statistical design. For each treatment, 4 bags and a total of 24 bags of 25 kg of fodder beet silage with different composition were prepared and transferred to storage at room temperature and after 75 days, all bags were opened and their pH, temperature and silage quality were immediately determined. A sample of each bag was used for chemical laboratory evaluation including DM, CP, Ash, NDF, ADF and ammonia nitrogen (AN). The results showed that adding 10 and 15% levels of wheat straw improved silage quality and reduced pH compared to the control (P<0.01). Addition of wheat straw had a significant effect on chemical composition and silage stability (temperature and pH) during opening (P<0.01), Addition of wheat straw reduced watery loss and increased silage quality (P<0.01). In general, the most suitable mixture of the silage was control + 15% wheat straw, which had a higher quality and longer shelf life.
