Show 7. Grass when cut and fed green to pigs, whether fed in pens or yards, or with full or part grain ration, or without grain proved to be of little value. 8. Pigs confined in pens and fed on grass alone, mostly lucerne, for 91 days, lost over a quarter of a pound per day. 9. The average of the pigs fed on grass gained a little more than those without the grass, but not enough to pay for the extra feed in the grass. 10. With the pigs confined in the hog-house pens the grass proved prov-ed beneficial, while with those in the yard it proved detrimental, the latter requiring more grain to make a pound of pork with the grass than without it. 11. Pasturing either with full or with part grain rations, appeared appear-ed to be by far the cheapest and best way of making pork. Note. The grass is a mixture of eight varieties in which lucerne constitutes at least one-half. The experiment station at Logan, ' . ' in Bulletin No. 40, gives the "val ue of grass and its Relation to Exercise, Ex-ercise, in the production of Pork," . a, with full grain rations; b, with part grain rations ; and c, with- out grain. After giving the various modes of proceedure and the results de-s de-s rived therefrom, for the years 1894-6 the whole is summed up in the following, which will give our readers a fair understanding o the best and cheapest mode in the production pro-duction of pork. ,1. Pigs allowed to run at, large over eighteen acres of good pasture past-ure and fed a full ration of grain, made the most rapid growth and required the least grain for one pound of gain. 2. Pigs confined in movable pens in the pasture grew more slowly than those running loose and required an increase of 20 per cent of grain to make one pound of growth. 3. Pigs at pasture,- fed under three conditions gained 92.5 per ceni more and eat but 2 per cent more than the pigs getting grass and otherwise similarly fed but confined in pens. The grain required re-quired to produce one pound of gain was increased 40 per cent with those in pens over those at pasture. 4. Pigs fed bat part rations of grain at pasture made satisfactory gains. Those at pasture getting the three-fourths grain rations gained more then those fed a full grain ration and grass, either in the yards or in the pens. 5.. Pigs pastured without grain made about the same growth for three seasons in succession, this averaging .36 of a pound per day. 6. As nearly as can be judged, , exercise alone increased the gain V 22 Per cent, and the amount eat-on eat-on but 1.5 per cent, but decreased the amount required for one pound of gain 22 per cent. |
