A tranquilizer fed to cattle (other than lactating dairy cows) prior to their being subjected to stress conditions such as vaccinating, shipping, weaning calves, and excessive handling.

Not less than.75 milligram but not more than 1.25 milligrams of additive per pound of body weight.

Additive should not be fed 72 hours before animals are slaughtered. There are three principal feed bunk types for dairy and beef cattle: (1) Fence-line bunks -- cattle eat from one side while feed is put in from the opposite side of the fence by self unloading wagons; (2) Mechanized bunks -- they sit within the feed lot, are filled by a mechanical conveyor above feeding surface; (3) Special bunks -- as discussed here, they permit cattle to eat from all sides. Feed is put in with an elevator.

Several materials or combinations of materials can be used to construct a satisfactory feed bunk. The selection of materials depends on skills of available labor for installation, cost of materials available locally, and your own preference. No one material is best for all situations. Selecting bunks by economic comparison is usually an individual problem.

Animals eat only from one side, so the fence-line bunk must be twice as long as the mechanical bunk. These bunks also serve as a fence, so part of the additional cost must be attributed to the fence. Because of their location, on the edge of the feed lot, fence-line bunks are not in the way of mechanical manure removal. Filling these bunks by the same self unloading wagons used to fill silos spreads cost of the wagons over more time and operations.
