Dairy Husbandry Section, Iowa Agricultural Experiment Station, Ames, Iowa
ABSTRACT
One of the difficulties in conducting feeding or digestion trials with cows is in having a suitable manger. For these purposes the manger should prevent wastage of feed due to the cows throwing it over the top of the manger in front of them or drawing it towards them among the bedding. In addition, cows should be prevented from stealing feed from each other.
A manger which has been in use in the Dairy Husbandry Section of the Iowa Agricultural Experiment Station for the last four years has been found very satisfactory. Sections of it are shown in figure 1.
It is constructed of galvanized iron with one-inch angle iron for joining the ends to the main body and the flange turned up in front is supported with 1-inch strap iron. On the stanchion post at each end of the manger there are two hooks. Each hook and its attachment consists of two pieces of 2-inch strap iron which are bolted around the stanchion post and the end of one of the pieces in each pair is extended and formed into a hook.
