Risks of Feeding Silages with Low Physically Effective Neutral Detergent Fibre
Popis výsledku v původním jazyce
The structural fibre given by the particle size has a significant effect not only on the fermentation processes of fodder preservation (the shorter and more eroded particles, the better the fermentation result) but also on the motor activity of the rumen. The physically effective fibre (peNDF) with particle sizes on a sieve of 8 and 19 mm was examined with the help of the Penn State Particle Separator (PSPS) in holstein dairy cows by Beauchemin and Yang (2005). They confirmed that the particle length is a reliable indicator of the rumination period, but it may not necessarily reduce the rumen acidosis. The review of prof. Forbes from the University of Leeds (Forbes, 2007) also gives evidence that the digestion of ruminants is not as simple as often presented. The rumen of dairy cows is a place of complicated digestion processes that increase the total acidity. If the acid contents in the rumen exceeds a specific limit (often set at pH 5.8), so called acidosis may occur and negatively affect the feed intake, the microbial metabolism, the production and quality of milk and the general health condition of the animals, including limb diseases (laminitis). The risk of acidosis can be reduced by higher proportion of physically efficient neutral detergent fibre (peNDF).
