BY G. S. FRAPS, Ph. D., OHEMIST IN CHARGE; STATE CHEMIsr. ____J ’ The value of a feeding stuff for feeding purposes depends upon several fngs. These include its bulk, its palatability, its ash content, its suit- 'ity to the animal, its vitamine content, its digestible protein and ‘f; productive value. The most important of these from the point of imal nutrition are the digestible protein and the productive value. DEFINITION OF TERMS. Digesiibie Protein.—Protein is the constituent of the feed which is f; t0 form lean meat, muscle, skin, hair, and similar portions of the y, secretions of the body which are necessary for life, and to replace _‘ repair animal tissue. The protein is equal to nitrogen multiplied . 6.25. , he digestible protein is that which is digested and absorbed during typassage of the food through the animal body. The digestible protein resents the capacity of the food to furnish material for the production flean meat, or for the repair or replacement of the tissues of the 7a] body. is made up of a variety of constituents and varies in character in ‘indifferent feeding stuffs. In the same feeding stuff, there are usually al different kinds of chemical compounds in the protein. , The "ins of some feeding stuffs appear to lack part of the essential con- ents for the proper replacement. or the repair of the animal tissues, for this reason are not as effective as they should be. The investiga- along this line are not yet sufliciently definite to permit satisfactory ments with regard to the qualities of different protein constituents eding stuffs. ' oduciive Valut@.-——Productive value means the value of the feeding to furnish the material for heat, for work, or for the production t; Protein, when digested, may be burned for the production of i‘ or energy, or its nitrogen may be split off and the residue used for formation of fat. Fats, whendigested, may likewise be used for or energy, or may be stored up for_fat. The same is true of the ;'tuents of the nitrogen-free extract and of that portion of the crude ; which is digested. he" work of digestion consumes a certain amount of energy which if‘ be furnished from that of the feed digested. Energy is also used etabolic changes consequent on the digestion of the food. The F; left after these uses are provided for may be used for productive hes, and this is what we term the productive value of a feeding " . w, 6 TEXAS AGRICULTURAL EXPERIMENT STATION. stuff. It is the value of a feed for the purpose of producing fat, after all of the requirements consequent on the consumption of the food have been deducted. The -fat may be burned for heat or used for work, or for material production of fat or milk. Feeding stuffs vary considerably in the amount of loss in the processes consequent upon digestion. For example, the digested constituents. of high grade cotton seed meal have a full value for the production of fat, but the digested constituents of Wheat straw have only one-fifth the value, pound for pound, of those of cotton seed meal. Feeding stuffs rich in crude fiber suffer a great loss in digestion, and the productive value is consequently lowered. The productive value is calculated from the results of tests with various feeds, in which the animal is first fed a measured ration sufficient to form a little fat and the quantity of fat determined. Then the animal is fed the same ration with the addition of the feed to be studied, and the quantity of fat again measured. The additional quantity of fat produced is due to the addition of the feed to be studied and rep- resents its fat producing power. ‘Ash of feeding stuffs is particularly important in growing animals, as it is necessary for the formation of bone, and certain portions of it are also required for the blood. Vii-amines are substances which are believed essential in the life of the animal, some of which appear to be absent from highly-milled materials or from their by-products. For example, they are not present in polished rice. They are, however, present in seeds and in meat, and in the leaves of plants. It is believed there are two different groups, and that one group is present in the seeds and another present in the leaves. The relationiof this matter to animal feeding requires further investigation. At present the matter appears of significance chiefly in connection with pigs, although possibly in connection with breeding animals. DIGESTION EXPERIMENTS. The productive values and the values for the digestible protein in this bulletin have been calculated from the results with digestion experiments on sheep. The method of conducting the experiments is the same as that described in Bulletins 147' and 166 of this Station. The production coefficients vrere calculated as described in our Bulletin 185. Details of the experiments are given in tables in the back of this bulletin or in connection with the feeds described. DESCRIPTION OF THE FEEDS AND DISCUSSION OF RESULTS. The composition of the feeds used and their average composition are shown in Table 1, together with the digestible protein and the productive value of the feed. The coeflicients of digestibility are given in Table 2. Table 3 contains the production coefficients of the various feedings stuffs. A discussion of the individual feeding stuffs is given below. 7 THE Psonnowxvu VALUES OF SOME TEXAS FEEDING STUFFS. 9H . .......>H..w w9w wwNN QwwH. w9w www . . . . . . . . . . . . . ..Nw H .Q 133E HEN 55 2E5 2H2 HHHHHwonH wvwhNw -.-- -.. . m .. . . . . . . . . . . . . . .

The grains were small, thick, and very hard. The sample showed indications of the corn having been heated and then dried. The corn Y was chopped before it was fed. _ According to the experiment, the corn has a greater feed value than the average corn chops. If we thereby conclude that Argentine corn chops is better than American corn chops, however, we would probably be in error, as one experiment is not sufficient to draw general con- clusions. _ v Bermuda Hag Used in Digestion Experiment '72. This hay was purchased in Bryan, Texas, and was of fair quality. It had a feeding va ue slightly above the average for Bermuda hay. Corn Silage Used in Digestion Experiment .46. This silage was made from strawberry corn harvested during the latter part of July. and after the kernels were well glazed. A quantity was brought to the laboratory daily, of which 750 grams were fed twice a day, making a total of 1500 grams. Five hundred grams were dried each day of the digestion period, which lasted six days. The preliminary 12 TEXAS AGRICULTURAL EXPERIMENT STATION. period was six days. This silage was furnished by the Feeding and- Breeding Station at College Station. The composition and feeding value were very near the average. Since corn silage contains about 75 per cent. water, the dry matter of corn silage has a high feeding value. Cotton Seed Used in Digestion Experiment 65. These seed Were secured from the Feeding and Breeding Station, and probably represented the average run of Texas seed, although the seed were not very well ginned, and carried a considerable quantity of lint. The seed were cut, and the hulls and kernels analyzed separately. They were then combined by calculation, in the proportion of 53.3 per cent. kernels to 46.7 per cent. hulls. Cotton seed contains more digestible protein, and has a slightly lower fat producing value, than corn chops. On account of its high oil con- tent, which is liable to interfere with digestion, it should not be fed in quantity to exceed 5 pounds per 1000 pounds live weight. Doliohos Ldblab Hag Used in Digestion Experiment 45. This hay was furnished by Mr. A. B. Conner, Agronomist, and was grown at Substation No. 3, Angleton, Texas. This hay contained 2'7 per cent. of large coarse stems, which were discarded. It contains more protein and has a. slightly higher fat producing power than Bermuda hay. Feterita Seed Used in Digestion Experiment 55. This seed was in good condition, but had been to some extent infested with weevils, and evidently treated with carbon bisulphide. This sample of feterita seed fed chopped had a higher feeding value than corn chops. On account of the small, hard character of the seeds, it should be ground or chopped before feeding. Otherwise, considerable proportion of the seed may escape digestion, and the corresponding feed—' ing value be lost. Feterita Fodder Used in Digestion Experiment '74. This was furnished from Substation No. '7, Spur, Texas. The stalks were about one-half inch in diameter at the large end, and there were very few heads. The sheep did not eat the large stalks very Well. The part that was eaten has about 50 per cent. more feeding value than milo fodder and about 25 per cent. more than kafir fodder. Jack Beans Used in Digestion Experiment 59. These beans were about the size of ordinary Lima beans, but were much thicker. They were clean, sound, and in good condition, but extremely tough, with a tendency to gum when chewed. They were chopped coarsely on a food chopper. This experiment was started with THE Paonnorrvn VALUES OF SOME TEXAS FEEDING STUFFs. 13 sheep, but one of the sheep refused to eat the beans entirely, and to be removed from the experiment. The other sheep did not eat in very well.

This feed was equal to wheat bran in productive value, though much lower in its content of digestible protein. Moth Bean Ifay Used in Digestion Experiment 41;. This was grown at Substation No. 3, at Angleton, Texas. It was planted July 4 in 6-foot rows, and germinated to a good stand in four days. On account of the dry weather of July and August, the growth was slow, and the plants bloomed, but failed to produce beans. When the early fall rains started in September, the vines put on new growth and were cut in this condition for hay, on November 8. The vines were cut with a hoe and taken immediately into a house and cured under shelter. ' This represents the hay of average quality. It had practically the same feeding value as dolichos lablab hay, and a little lower than average alfalfa. Peanut Hulls Used in Digestion Experiment 52. This feed consisted of the crushed peanut hulls, containing the out- side covering of the peanut kernels, or peanuts, with a small amount of peanut fragment. Some stems from the vine were also present. These had a very low feeding value, and the feeding value present was probably due to the particles of meats left in them. l Peanut Hay With. Nuts. Hay used in Digestion Experiment 40: This consisted of the peanut vines carrying the nuts. The vines and nuts were separated and pre- pared and weighed separately into the rations. The rations consisted of 1'75 grams of vines and 75 grams of nuts. The peanuts with the vines contained '70 per cent. vines and 30 per cent. nuts. It was of good quality. _ , Peanut Hay with Nuts, used in Digestion Experiment '77, contained 136.8 grams peanuts to 163.2 grams hay. This hay was separated, pre- pared separately and weighed out separately in the rations at the rate of 135 grams of nuts to 165 grams" of hay. The hay contained the leaves, stems, roots and the nuts.‘ The peanuts were grown at Substation No. 11, at Nacogdoches, and were furnished through Mr. A. B. Conner. Peanut hay with the nuts on is a rich feed, better than wheat bran. It has, however, a high fat content, and for this reason, and also on account of its high value, should be fed in connection with other rough- age. If fed alone, it is a. highly fattening food, and the animal would be liable to get too much fat so as to impair digestion. Peanut Hay Without Nuts. The feed used in Digestion Experiment No. '76, consisted of the ha} from which the nuts had been removed. They were furnished by Substa- tion No. 11, Nacogdoches, Texas, through Mr. A. Conner, Agronomist True PRODUCTIVE V ALUES or SOME TEXAS FEEDING STUFFs. 15 Peanut Hay used in Digestion Experiment 41 is the same feed as used in Digestion Experiment 40, and consisted ofthe hay from which the nuts had been removed. Hay used in Digestion Experiment 69: This sample was secured by Mr. H. Eliot, of the Extension Service, from Mr. H. B. Shackle- ford, of Cross Plains, Texas. This hay contained only a small amount of nuts. The three samples gave closely agreeing results in productive values, though somewhat different in digestible protein. It is a good feed. Peat Used in Digestion Experiment 67. This peat was furnished by the Weidmer Chemical Company, of Saint Louis, and is a natural deposit which is dried and heated to a compara- tively high temperature. The manufacturers do not claim a feeding value for this material. but claim that it acts as an absorbent to take up or counteract the bad effect of molasses or sweetened animal food. The material was labeled, “humus for fertilizer and stock food.” It had the appearance somewhat of finely ground charcoal, except that it con- tained some finely divided brown to gray material. The digestion experiment showed that this material was not only not digested, but that it apparently decreased the digestibility of the alfalfa hay, with which it was fed. Prairie H ay. Southwest Texas Prairie Hay, used in Digestion Experiment 38, was commercial southwest Texas prairie hay. Prairie Hay used in Digestion Experiment 61 was cut from the wild . prairie grass, the middle of June, 1914, on the experiment farm near _ Angleton. It grew on flat, poorly drained soil and had an abundance of rainfall until within three weeks of the time it was cut for hay. It was almost mature when cut. The hay consisted chiefly of two native wild grasses and a mixture of various weeds. The smell of bitterweed was very noticeable. The hay was furnished by Mr. N. E. Winters, Superin- tendent of Substation No. 3, Angleton, Texas. -- ‘ Rhodes Grass Hay Used in Digestion Emperimeent 82. This hay was furnished by Mr. E. H. Clark, La Feria, Texas, and was grown in the" lower Bio Grande Valley. It was cut late, and is, therefore, i l » somewhat more woody than the best quality of Rhodes grass hay would be. It has a good feeding value. Rough Rice. These three samples used in Digestion Experiments 49, 50, and 51, ° were furnished by Mr. n. A. Eignus, Secretary of the Southern Rice Growers’ Association, at Beaumont, Texas, and consisted of the rough rice, that is, the grain and the husks, which had been ground up. The 16 Ufisxxs AGRICULYJTIIRAL EXPERIMENT STATION. rough rice used in Digestion Experiment ~19 was “stack burnt,” that is, had undergone a heat or fermentation while stacked up y: that used in Digestion Plxperinient 5U was musty and damaged; that used in Diges- tion Experiment 51 was sound and of the best quality. All this rice wasof the Honduras variety. ' There is little difference in the feeding values of the three grades of rice as shown in the digestion experiments. Bough rice has a good feeding value. It should be ground, as otherwise the hard grains will escape mastication. Rice Hay Used in Digestion Esvpveriment 78. This consists of second growth rice hay harvested when in milk to early dough stage. It was produced from stubble about seven weeks after the rice harvest, and yielded about one to one and a half tons to the acre. This hay was secured from Substation No. 4, Beaumont, Texas, through Mr. A. B. Conner, Agronomist. _ The feeding value is not high, about the same as prairie hay. SOTQhZL-fll Silage Ifsed in Digestion Ewperimient 47. This silage was furnished by the Feeding and Breeding Station and was brought to the laboratory every day and 1500 grams fed to the animals. Five hundred grams were weighed out and dried for the estimation of dry matter. The silage was made from the Sumac variety, " planted in cultivated rows, and was harvested in August as soon as the seed were entirely ripe. 4 This sorghum silage was 50 p-er cent. better than the average. »S’0rgh¢u.m H ag Llserl in Digestion Ercperinzient 1,3. This hay was of good quality. About half of the heads were not ripe. Its value was slightly below the average. Shallu Fodder. Furnished by Substation No. 8, at Lubbock, Texas. This forage was of good quality, although some of the stalks ivere rather large. This is about equal to milo fodder and slightly better than kafir fodder. Sudan H cg. Sudan Hav used in Digestion Experiment 39 was cut when headed and approaching the milk stage. Sudan Hay used in Digestion Experiment 60 was about four feet high and most of it in full tassel when cut. i Sudan Hav used in Digestion Experiment 62 was cut just before it was in full bloom and when it was well headed. It is supposed to have been cut at the best stage for making hav. Sudan Hay used in Digestion Experiment '73 was a late cutting of THE PRODUCTIVE VALUES OF SOME TExAs FEEDING STUFrs. 1'7 the Sudan Grass and some of it was rather coarse. There was also a high percentage of Crab Grass present, the amount being estimated at 40 per cent. Mr. A. B. Conner states that it is probable that in cutting, in a good many sections, the last cutting of Sudan Grass will contain con- siderable Crab Grass. ‘ Sudan Hay varies from 0.8 to 7.2 in digestible protein and 6.1 to 8.6 in productive value. The average is about the same as Bermuda Hay. Cut at the best stage of growth, just before it was in full bloom, and when well headed, it had a productivevalue about the same as alfalfa, though the digestible protein was less. Sudan Straw. This was used in Digestion Experiment 42 and is Sudan Straw, after the seed crop has been removed, and the remaining straw baled up. It has a lower feeding value than Sudan Hay. Wheat Ski-arts. This sample was almost pure white and contained little of the bran particles. It is really almost a low grade flour, rather than wheat shorts. - This sample xvas much better than average wheat shorts in digestibility. It was used in Digestion Experiment 64. MAINTENANCE REQUIREMENTS. In Experiments '72 to 82 we collected and analyzed the urine. The animal stood on an iron screen above a galvanized funnel. The urine n went into a suitable receptacle. Every day it was made up to volume (usually 500 cc.) in a graduated flask, and two portions of 1 per cent. . each measured out for analysis.(usually 5 cc.). One-tenth of the urine ‘was put into a bottle each day and at the end of the period, the com- bined aliquots were also subjected to analysis. The average daily - analysis and the analysis of the total urine usually showed an excellent agreement. The average of all'was taken to be the daily excretion of nitrogen. The urine was usually made up to 500 cc., but in some cases the excretions were excessive and it was made up to 2000 cc. Table 4 shows the nitrogen digested ‘and excreted and the nitrogen balance. It also shows the weights of the sheep from Experiment '76 ‘d’ _ on, and the productive value in terms of fat, of the feed digested. In Bulletin 1'70, we gave the maintenance ration ofisheep of coarse breeds as being 1 pound proteids and 2.08 pounds production value per 100 v pounds of live weight. "This ration would be equivalent to 50 grams protcids and 104 grams productive value per 50 kg. sheep, which is approximately the sizes of those used in the experiments. This ration is not the ration which would just sustain the body, but permits growth of wool and some growth of body organs. The true maintenance re- quirements would thus be less. l 0.5 fihm 00000 £20m 00.? ~0.N 8.0 0.3 0.00 m» xmxxmmuunnnnnuwnoz 080m m . mm 0H2 $.50 000% 00 . ml E . m 00 . ~ w . 2 0 .

There are gains of nitrogen when the ration contains 5 grams nitrogen (Experiment 76) and comparatively small losses with 4.78 grams per day. Some of the rations fed were very low in protein, and with these the animal was able to reduce its use of nitrogen to three grams per day in many cases, or even to two grams or less. This would be equivalent to 0.25 pounds proteids per 1000 pounds live weight. The actual body use is thus reduced to a very low amount, as is shown also in experiments on stormy days. None of the rations examined had a productive value of 104 grams per 50 kg. sheep. Yet, to judge from the live weight, several of these . rations maintained the iveight of the animals. This occurs in the follow- ing cases: Sheep No. 1, peanut hay, 83 grams productive value. Sheep No. 2, rice hay, 33 grams productive value. Sheep No. 3, rice hay, 19 grams productive value. Sheep No. 2, kafir forage, 33 grams productive value. Sheep No. 2, milo forage, 27 grams productive value. Sheep No.1, Rhodes grass hay, 26 grams productive value. With other sheep on the same ration, as given in the table, xveight was not maintained. These weights covered a period of 12 days. It has been pointed out by the Missouri Station that an animal may m.ain- tain its weight but lo-se in condition or fitness?“ Therefore the main- tenance of weight alone is an unsafe method of testing rations for maintenance. If we judged from the weights in these experiments, we might conclude that a ration containing 35 grams productive value is suflicient for the maintenance of a 50 kg. sheep. This would be equiva- lent to 0.7 pounds productive value instead of 2.08 per 1000 pounds live weight.“ We do not, however, draw this conclusion, but merely ' observe, that the ‘ration with 2.08 pounds productive value is probably p.14 <_, l“. posed to be when formulated. more largely in excess of the maintenance requirements than it was sup- Investigations along this line will be continued, for the knowledge of the maintenance requirements is im- portant in studying the productive values of feed and of rations. *Mo.
