Volatile fatty acid proportions and microbial protein synthesis in the rumen of cattle receiving grass silage ensiled with different rates of formic acid

Abstract: Timothy-meadow fescue herbage was ensiled with formic acid (FA) (expressed as 100% solution) at the rates of 0, 2, 4 or 6 L t )1 . The silages were fed along with concentrates to bulls fitted with cannulae in the rumen and duodenum. The ration comprised grass silage (700 g kg )1 ), barley (240 g kg )1 ) and rapeseed meal (60 g kg )1 ). The application rate of FA had no effect on the site or extent of the digestion of dietary organic matter (OM) and neutral-detergent fibre. The flow of total N at the duodenum i… Show more

“…Intake results were not related to digestibility data, since FA application rate had no marked effect on OM digestibility in accordance with earlier experiments using sheep (Chamberlain et al 1982) and cattle (Jaakkola et al 2006). In general, the effect of FA treatment on silage intake depends on the application rate and the material ensiled (Harrison et al 2003), and consequently on the fermentation quality of the silage.…”

“…The extent and type of silage fermentation may be modified by differences in grass composition and epiphytic flora. Compared to our previous study with the same FA application rates (Jaakkola et al 2006), the present grass had a higher DM (159 vs. 267 g kg -1 ) and WSC (72 vs. 129 g kg -1 DM) concentration, and therefore was easier to ensile. As a result, the untreated silage underwent a predominantly lactic fermentation.…”
