Effect of silage type and supplementation with sucrose or lactic acid on rumen fermentation in dairy cows

Extract
Recent studies have shown increased silage intake and improved milk fat concentration in dairy cows offered restricted compared to extensively fermented silages (Chamberlain et al., 1990; Mayne 1992). Changes in milk composition may be related to increased intake per se and/or alterations in rumen fermentation parameters. A study was therefore undertaken to examine the effects of silage fermentation type, dry matter intake and the addition of water soluble carbohydrate (WSC) or lactic acid on rumen fermentation parameters in dairy cows.
Two direct cut grass silages were prepared using either an inoculant (Ecosyl, 3 1/t, ICI. pic) or Maxgrass (BP Chemicals, 6 1/t). Five silage only treatments were offered to four ruminally fistulated dairy cows in a five period, partially balanced, changeover design experiment. Each period was of 4 weeks duration. Treatment 1: Inoculant treated silage (I), 2: Maxgrass silage (M), 3: Maxgrass ad-libitum (MAL), 4: Inoculant + sucrose (500 g/day) (IS), 5: Maxgrass + lactic acid (200 ml/day) (ML).
