摘要:
An improved ruminant feed containing rumen stabilized particulate proteinaceous feed material which is unstable in solutions having a pH value smaller than 4 and relatively stable in solutions having a pH value larger than 5, said feed composition including at least one non-proteinaceous nitrogen compound. The non-proteinaceous nitrogen compound is present in a weight ratio of 0.1 to 10.0 based upon the weight equivalents of nitrogen in the rumen stabilized albuminous component.

The fertility of female mammals can be improved by dispensing once or within a short time repeatedly a high dosage of tyrosine. The dispensation can be carried out at will intravenously or orally.
摘要:
An assembly for handling a fluid, comprising a valve and a controller. The valve has at least one revolving valve element and a coupling device. The coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device. The controller is adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.

摘要:
A roller press for compacting and briquetting bulk material having rollers, each comprising a core, segments arranged adjacent one another around the surface of the core, adjusting springs by which the segments are fixed on the roller core in the circumferential direction, clamping rings having frusto-conical faces on projections which abut frusto-conical faces on projections on the segments, and clamping bolts extending through the clamping rings and passing between the longitudinal edges of the segments. Each clamping ring is provided at its inner circumference with adjusting spring grooves parallel to the axis of the clamping ring and the adjusting springs for the segments extend parallel to the axis of the roller beyond the end of the segment to such an extent that they engage in the adjusting spring grooves in the clamping ring.
