title: [Digestibility and utilization of rations containing differently treated straw. I. Digestibility by sheep of rations containing differently treated straw].
abstract: During 63 digestibility periods of adult sheep, the digestibility of wheat and oat straw sujected to different kinds of treatment was compared. The straw was fed in the following forms: chopped, chopped and treated with 6% sodium hydroxide, pelleted without and with NPN-addition (ammonium bicarbonate and/or urea) during pelleting. Notwithstanding pressing temperatures over 90 degrees C and light moistening of the straw during pellet production, the addition of the two NPN-components did not allow to increase digestibility and energetic feed value. Two replications averaged an increase in energetic feed value by 42% due to NaOH-treatment. Energy digestibility went up by 39 to 55%, and energy concentration increased from 322 to 457 energetic feed equivalents (cattle) per kg DM. In addition, a number of rumen-physiological indices were obtained.
