Abstract

The objective was to evaluate the fermentation parameters, chemical composition and in situ degradability of sesame silage in comparison to usual silages. The losses, fermentation quality and chemical composition of the forages and silages were evaluated using a completely randomised design with four treatments (sesame, corn, millet and sunflower) and four replicates per treatment, the silages were produced in experimental silos. In-situ degradability was evaluated using a completely randomised design with four treatments and three replicates (animals) per treatment. The results were statistically evaluated by analysis of variance and Tukey’s test with a level of 5% of probability. Three rumen fistulated non-castrated Santa Inês rams were used. Sunflower and corn silages presented higher percentages of losses through gases (p = .0256). Millet silage presented higher losses by effluent (p < .0001). The dry matter recovery (p < .0001) ranged from 70.0 to 96.5% for sesame and corn silage, respectively. The dry matter content (p = .0002) in the silages ranged from 280.0 to 429.4 g kg−1. The sesame silage presented loss amounts and fermentation parameters similar to those found in corn and sunflower silage. Sesame silage showed moderate dry matter (DM), content, excellent crude protein (CP) and total digestible nutrients (TDN) contents, and low lignin content. Corn silage presented higher concentration of the soluble fraction of DM (p < .0001). The sesame silage presented a high degradability rate of DM and it was similar to corn and millet which have great nutritional potential for ruminants feeding. Sesame has the potential to produce quality biomass and silage for animal feeding.

    highlights

  • The sesame can be an option for silage making.

  • Sesame helps to ensure sustainability by promoting lower seasonal risks in this region through the usage of silage as feed for the animals.

  • Sesame also increases the productivity of livestock throughout the year, through the availability of feed for the herd mainly during the dry season of the year.
