Abstract: Local/toll dynamic routing integration is achieved within a telecommunications network (14) that includes at least one dynamic routing local switching system (24-1) for receiving incoming call and a plurality of toll switching systems (27-1 through 27-7) at least one of which is associated with each local switching system. For each incoming call, the local switching system (24-1) derives a set of Class-Of-Service (COS) parameters indicative of the class-of service associated with the call. In accordance with the COS parameters, the local switching system (24-1) determines whether each incoming call is a featured call, requiring routing to the toll switching system associated therewith, or a non-featured call. Featured calls are routed to the toll switching system associated with the local switching system for feature processing, whereas non-featured calls are routed by the local switching system itself in accordance with the COS parameters, thus relieving the load on the associated toll switching system.

Abstract: A telecommunications network (10) includes an Originating Switching System (12.sub.1) and a Terminating Switching System (12.sub.2) linked by a plurality of trunks (20.sub.1 -20.sub.4). For each incoming call it receives, the Originating Switching System establishes a Circuit Selection Capability Indicator (CSCI) value that determines what enhancement, if any, the Originating Switching System will provide to the call. The Originating Switching System also utilizes the CSCI value to select an appropriate trunk that is compatible with a type of call enhancement, if any, to route the call to the Terminating Switching System which also enhances the call in accordance with the CSCI value. Determining the call enhancement in accordance with the CSCI value allows different types of calls which are routed on the same trunk to get different call quality enhancements, depending on the call type.

Abstract: This invention concerns the delivery of anti-parasitic agents to ruminant animals. More particularly, the invention concerns delivery of such agents in a controlled manner to enable the agent to have maximum effect on the parasite for longer times than is possible with conventional formulations. The composition of the invention comprises a benzimidazole, macrocyclic lactone, organophosphate, salicylanilide/substituted phenol, tetramisole or pyrimidine anti-parasitic agent dispersed in a medium the solubility characteristics of which are such as to ensure that, following oral administration, controlled amounts of the anti-parasitic agent become available to the parasite, either directly or by absorption into the ruminant blood plasma, during passage of the composition through the rumen, the abomasum and the intestine.

Abstract: This invention relates to techniques for improving the efficiency of feed conversion, growth and yield of meat from ruminant livestock. There is provided a method of improving the growth rate and modifying the carcass quality of ruminant livestock. The method includes simultaneously feeding to the animal a protected protein meal and, in addition, a protected lipid in amounts which synergistically improve the growth rate and modify the carcass quality.
