The Composition of Corn Fodder Grown In Drouth Years 1. D. HAIGH AND A. G. HOGAN The period of drouth in Missouri, accompanied by an almost complete corn crop failure, resulted in the production of much corn which could be used for fodder only. Corn grown in the drouth year of 1934 on the Experiment Station farms and fields was cut for feed and for preparation of silage. The Department of ALnimal Husbandry collected samples of these materials as they were used for feeding and brought some to the laboratories of the Experiment Station for analysis,* The data obtained are presented in this bulletin. The composition of corn stover produced in a normal year is compared with that produced in a drouth year in Table 1.

All of these stood in shocks for two to six months before sampling. The composition of two lots of corn stover (II and III) produced in the drouth year 1934 are also indicated. Series II was from river bottom corn producing 30 bu. of corn per acre. Series III came from upland corn producing no ears but possibly a few nub-bins. This sample is designated as stover, though no ears were removed. The composition of all these samples is given on the "The chemical an4tlyses were cOii:ducted under· the . directionot E. W. Cowan of the Department of Agricultural Ohemistry. 4 MISSOURI AGRICULTURAL EXPERIMENT STATION basis of an average moisture content for stover of 25 per cent. The difference we observe is in the higher protein content of the drouth stricken stover. The carbohydrates are practically iden-tical and the other constituents show little if any variation from it normal corn stover. The data presented in Tables 2 and 3 were obtained by the analysis of immature corn plants cut in the month of August of the drouth year 1934 from plots on Sanborn Field (Series I) and from experimental farms near Columbia (Series II). In Series I, a distinctly dry sample and a partly green sample were gathered from each plot, and after drying the two parts were combined for analysis. In Series II the samples were made up of a dried-up sample and a partly green sample from each plot which were analyzed separately. Complete data on fresh weights and yields were not obtained for Series II. The effect of drouth con-ditions is best indicated by considering the composition of these materials on the dry basis.

Differences in composition of the sa:tnples of Series I, Table 2, at the time of cutting are not conspicuous, with the exception of the crop grown on plot 17 which received no fertilizer treatment. This sample is lower in protein and higher in carbohydrate than the others. Plots 3, 18, and 25 to which manure or fertilizer had BULLETIN 390 5 been added, and also sweet clover plot C-West, produced corn of higher protein content than the plots receiving no treatment, or the manure and rock phosphate treatment. Other constituents show little variation dtle to soil treatments. Considering the composition of the samples of Series II, Table 2, we note that the samples most completely withered by the drouth tend to exhibit higher protein and crude fiber percentages. The short and tall growth samples from the Hinkson bottom farm are the exception to this statement. Hand in hand with high percent-ages of crude fiber occur somewhat lower percentages of nitrogen-free extract resulting in a constant va:lue for total carbohydrates in some cases. In others the green material tends to show slightly higher percentages of total carbohydrate than the dried sample. In Series I, Table 3, the yields per acre show that the plots which received applications of fertilizer or manure gave distinctly TABLE 3.-YIELDS OF CORN PLANT CUT IN AUGUST 1934 AS DROUTH STRICKEN CORN.

The drouth has of course a large influence on the yield but the effect of fertilizer treatment is plainly evident even in the dry season. The composition of corn silage produced from the drouth stricken corn is given in Tables 4 and 5. These data are percent-ages as fed. In order to compare differences the data in Table 5 are caJlculated to- a dry basis. TABLE 4.-CORN SILAGE, AVERAGE COMPOSITION AS FED. Description 1.

This is the difference one would expect in the composition of the young as compared with the more mature corn plant which is normally used for silage. The Atlas sorgohum used for prepa'ring the above silage (IV) was grown in the drouth year of 1934. It made but a small growth in the dry season but with the onset of fall rains it began to grow vigorously. It was placed in the silo in October and the above sample of the resulting silage was taken from lots removed in November. The composition of this sorghum silage tends to ap-proa'ch the composition of normal corn silage as far' as' carbo-hydrate and protein is concerned, but its percentage of crude fiber is distinctly higher. Thus we would infer that it is somewhat inferior to normal corn silage from the standpoint of compositioll alone. Timothy and wheat cut in June when growth has been stopped by the drouth was made into silage and used as a drouth feed. Composition of timothy and wheat hay and of the silage produced from the hay may be compared by observing the data in Table 6. TABLE 6.-TIMOTHY AND WHEAT, HAY AND SILAGE.

When made into silage significant amounts of the more readily sol uble portions of the mineral matter, protein and carbohydrate have been removed and the percentage of crude fiber increased, thus lowering its food value.
