Show MINERAL MIXTURE NEEDED BY SWINE Grain and Forage Rations Must Ee Supplemented. i ) i Tlmt the ordinary grain and forage I rations used for feeding our hogs must ! be supplemented with a mineral mix- j ture Is a fact upon which ull Invest!- ! gators agree. A typical statement re- j lating to this subject was recently j made by A. Severson of the North j Dakota experiment station, as follows: j "The ordinary grain ration does not contain the variety nor a proper amount of mineral matter required to rapidly develop a large frame for early i maturing hogs. One can expect a con- siderable percentage of weak, under sized or unthrifty pigs when no mineral min-eral mixture is used. Without m:n- j erul matter sows are apt to go down ; in the back, become weak in their pasterns and many times become so week they cannot get up when nursing nurs-ing a large litter of pigs. The milk drains heavily on the skeleton of the sow to supply the proper amount of ! mineral to the milk. The constant . addition of mineral matter to the j eow's ration will avoid this ailment. I Hogs are more apt to suffer from mineral deficiency than other classes of live stock." Such products as tankage and skim milk are rich in mineral matter, but under average farm conditions they are seldom, if ever, fed in large enough quantities to supply tlie amount needed. Those who have been carrying their pigs on a light grain ration with perhaps a rather skimpy pasture should not overlook the feeding feed-ing of a liberal supply of minerals. |
