Abstract
Kruczyńska, N., Darul, K. and Nowak, W. 2002. Effect of mowing height on nutritive value of maize silage. J. Appl. Anim. Res., 22: 213–218.
Investigations encompassed maize silages prepared from varieties: Rasant FAO 200, Dragon FAO 210, LG 2252, FAO 230, San FAO 240 and Magister FAO 270. Dry matter content in case of plants mowed at the height of 15 cm (A) ranged from 33.4% (LG 2252) to 38.5% (Magister). Differences between varieties in terms of the chemical composition of silages were slight and not unidirectional. An increase in the height of mowing from 15 cm (A) to 55 cm (B) resulted in significant increase in the concentration of dry matter, decrease in the amount of structural carbohydrates (ADF, NDF) and improved NDF degradation in the rumen. Variety LG 2252 was characterized by the lowest ruminal degradation of starch. Starch digestibility in the whole digestive tract was 99–100 per cent.
