Description

This experiment was conducted in cooperation with the departments of Agricultural Engineering, Animal Husbandry and Dairy Husbandry of South Dakota State College. The department of Agricultural Engineering ground the grains and roughages with a burr grinder. For power a tractor was used, such as is found on any farm where grinding is practiced. The departments of Animal Husbandry and Dairy Husbandry fed these ground grains and roughages to livestock of the different kinds. There has been for some time, and there is today a demand for information along these lines because some farmers who have purchased tractors to assist with the farm work are eager to utilize this machinery to the best advantage during the idle period. Naturally, the question of grinding all the roughages and grains grown on the farm before feeding to all kinds of livestock is suggested. This experiment did not include all of the grains and roughages but only some of those that are more commonly grown in the state. We know there are feeds that would be more palatable for some livestock if ground than unground. Palatability is an important factor in all feeding operations. The practice of mixing ground grains and roughages at the time of grinding has been advocated by some; because of this we fed the ground feeds mixed, as well as in separate troughs, to learn whether there was any great advantage in feeding in this manner. Therefore, this bulletin not only includes the advantages and disadvantages of feeding ground grains and ground roughages, as such, in separate troughs but the advantages and disadvantages of feeding the ground feeds mixed. There are more mixed feeds for sale at the present time than ever before. In some cases feeds are mixed while being ground, but in our mixing we aimed to mix the same quantity of each as animals were consuming when the ground feeds were fed in separate troughs. It required time to mix these feeds daily but in figuring the cost of producing 100 pounds of gain we have not included anything for this chore.
