Results of Feeding Experiment with Silage Processed by Technology of Shredlage

Popis výsledku v původním jazyce

Any improvement in usage of maize silage is of a considerable significance because this feed is basic roughage with a high concentration of energy in the form of starch, and digestible neutral detergent fibre (NDF) for feeding rations in cows. When using the technology “Shredlage”, thanks to patent rollers in a cutter, the long chopped forage (26-30 mm) is crushed more intensively, corn grains are ground better and in the same time particles of chopped forage are lengthwise broken – they are unravelled, corn cobs are ground and bark of stems is separated from core. Due to longer chopped forage, content of physically effective fibre is enhanced and therefore, a number of its donators (hay, straw) can be reduced, and die to it, a portion of maize silage may be increased. Simultaneously, better availability of starch and the extended surface of particles should lead to better digestibility of forage chopped processed in the way above mentioned. All these facts should be resulting in higher dry matter intake, better working of the rumen, better health state and subsequently, in better milk performance for about 1 lit/day per cow. Beintmann et al. (2016) did not find differences in milk performance in a similar experiment, however, the maize “shredlage” silage improved supplementation of dairy cows by energy, and negative energy balance (NEB) at the beginning of the lactation period was lower.
