Least Cost Rations for Beef Cows

Winter feeding costs represent between 50 and 60 cents of every dollar spent on keeping a cow a year. Thus, any attempt to control or reduce costs of operating a cow herd must focus on controlling or reducing feed costs. However, attempts at controlling or reducing costs are highly dependent on the forage system that the cow-calf operation uses. Forage systems vary depending on a variety of fac...

Least-Cost Opportunistic Routing

In opportunistic routing, each node maintains a group of candidate relays to reach a particular destination, and transmits packets to any node in this group. If a single candidate relay receives the packet, it becomes the effective relay to forward the packet further. If no candidate receives the packet, then the current sender re-transmits. If multiple candidates receive the packet, then the l...

Disinfection of livestock production premises.

Livestock production premises (e.g. barns, and pens for lambing, calving, weaning and holding animals) encounter disease problems mainly associated with the housing of new-born and young animals, pregnant females and suckling mothers. The author describes a programme of cleaning and disinfection for use during the routine operation of livestock premises. A further programme is described for use...
