S. FRAPS, PH. D., Omar, DIVISION 0F CHEMISTRY 3 STATE CHEMIST The value of feeding stuffs for feeding purposes depends upon several things. These include its bulk, its palatability, its ash contents, its suitability to the animal, its vitamine contents, its digestible protein and its productive value. The most important of these from the standpoint of animal nutrition are the digestible protein and the productive value. DEFINITION OF TERMS Digestible PTOt6i7b.'——PI‘Ot6lIl is the constituent of the feed which is used to form lean meat, muscle, skin, hair, and similar portions of the body, secretions of the body which are necessary for life, and to replace and repair animal tissue. The protein is equal to nitrogen multiplied by 6.25. I The digestible protein is that which is digested and absorbed during the passage of the food through theanimaPs body. The digestible pro- tein represents the capacity of the food to furnish material for the pro- duction of lean meat, or for the repair or replacement of the tissue of the animal body. It is made up of a variety of constituents and varies in character in the different feeding stuffs. In the same feeding stuff there are usually several different kinds of chemical compounds in the protein. The pro- teins of some feeding stuffs appear to lack part of the essential con- stituents for the proper replacement or the repair of the animal tissues, and for this reason are not as effective as they should be. The investi- gations along this line are not yet sufficiently definite to permit satis- factory statements with regard to the qualities of different protein con- ‘ stituents in feeding stuffs. Productive oalue.—Productive value means the ability of the feeding stuff to furnish the material for heat, for work or for the production of fat. Protein, when digested, may be burned for the production of heat, or energy, or its nitrogen may be spilt off and the residues used for the formation of fat. Fats, when digested, may likewise be used for heat or energy, or may be stored up for fat. The same is true of the constituents of the nitrogen-free extract and of the protein of the crude fiber which is digested. The work of digestion consumes a certain amount of energy which 6 TEXAS AGRICULTURAL EXPERIMENT STATION. must be furnished from that of the feed digested. Energy is also used for metabolic changes consequent on the digestion of the food. The energy left after these uses are provided for may be used for productive purposes and this is what is termed the productive value of a feeding stuff. It is the value of a feed for the purpose of producing fat, after all 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 cottonseed 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 cottonseed meal. Feeding stuffs high 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 vari- ous 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 ani- mal is fed the same ration with the addition of the feed to be studied, and the quantity of fat produced again measured. The additional quan- tity of fat produced is due to the addition of the feed to be studied and represents its fat producing power. The productive value may be studied in terms of matter, such as fat, or in terms of energy, such as therms. Ash of feeding stuffs is particularly important in growing animals, as it is necessary for the formation of bones, and certain portions of it are also required for the blood. Vitamines are substances which are believed essential in the life of the animal. some of which appear to be absent from highly-milled ma- terials 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 in the leaves. The relation of the matter to animal feeding requires further investi- gation. At present the matter appears of significance chiefly in con- ne-ction with pigs, although it may possibly be important 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 No. 147 and 166 of this Station. The pro- duction coefficients were calculated as described in Bulletin No. 185. Details of the experiments are given in tables in the back of this bulle- tin or in connection with the feeds described. FEEDING VALUES or CERTAIN FEEDING STUFFS. '7 COEFFICIENTS OF DIGESTIBILITY The coefficients of digestibility are used to calculate the digestible constituents of a feeding stuff, and until about ten or fifteen years ago the digestible nutrients were used exclusively for calculating rations in the feeding of animals. Developments in scientific knowledge concern- ing feeding stuffs have rendered the use of digestible constituents in feeding stuffs an antiquated method, although many people are still using them. The digestible nutrients do not show the real feeding value of the feeding stuff, for the reason that the nutrients digested are not of equal value to the animal body. An illustration of this may be given by comparing the digestible nu- trients of cottonseed meal and cottonseed hulls. These are given in table 1. The total digestible nutrients of 1.00 pounds cottonseed meal are 67.6, while for cottonseed hulls they are 35.3. One pound of cot- tonseed meal would therefore be equal to only 1.9 pounds of cottonseed hulls, based on the digestible nutrients. Any feeder knows that this is not correct, and scientific experiments have shown that it is highly in- correct, as cottonseed meal has a much higher feeding value.

In either case, the productive value represents more closely the actual feeding value than the sum of the digestible nutrients. For example, the cottonseed meal is given in table 1 as having a productive value of 17.1 and the ‘cottonseed hulls a productive value of 4.1. One pound of cottonseed meal would therefore equal in feeding value 4.2 pounds of cottonseed hulls. This is confirmed by experiments. The misleading character of the comparison of the digestible nu- trients is shown clearly when money values are compared. If the cot- tonseed hulls sell for $20 per ton, and the cottonseed meal for $60 per ton, one pound digestible nutrients in cottonseed meal would cost 4.4 cents and one pound in cottonseed hulls would cost 2.9 cents. Cotton- seed hulls are apparently cheaper than cottonseed meal. 8 TEXAS AGRICULTURAL EXPERIMENT STATION. But if the cost of the units of productive value are compared, one finds that one pound productive value of cottonseed meal costs 17.2 cents, while one pound productive value of cottonseed hulls costs 24.4. Therefore, the cottonseed hulls at $20 per ton are much more expensive than the cottonseed meal at $60 per ton. The comparison of the digest- ible nutrients of the cottonseed meal and cottonseed hulls have given entirely misleading results. Feeders have not been willing to pay $20 a ton for cottonseed hulls when the meal was sold at about $60. If the productive values are correct for feeding purposes, they were right. If the values based on the digestible nutrients are right, they were wrong and should have purchased the hulls. But the values based on the di- gestible nutrients are not right. If the productive values in the hulls are assumed to be worth 17.2 cents, then the value per ton would be $14.10. During the past season roughage has sold at prices in excess of its feeding value based upon the productive value, at least in Texas, on account of the scarcity of roughage due to the drouth. DESCRIPTION OF FEEDS AND DISCUSSION OF RESULTS The composition of the feeds used and the average composition are shown in table 2, together with digestible protein and the productive value of the feeds. The coefficients of digestibility are given in table 8. Table 9 contains the production of coefficients of the various feeding stuffs. A discussion of the individual feeding stuffs is given below.

FEEDING VALUES OF CERTAIN FEEDING STUEEs. 11 Acorns The investigation of the composition and digestibility of acorns was begun at the request of D. '1'". Griswold of the Extension Service. A number of samples of acorns were collected through his agency, and submitted to analysis, and one digestion experiment Was made. Analyses of the samples of the‘ acorn hulls a11d kernels are given in tables 2, 3, 4, 5, 6, '7. The acorn kernels classify into tWo entirely different groups, as shown by the chemical composition. In one group, containing acorns from the red oak, Water oak, blackjack, willow oak, and blue jack, the acorns are rich in fat. In the other group, containing acorns from the shin oak, live oak and post oak, the acorns are low in fat. The fat content of the acorns of the first group is so high that it Would be practicable to extract it from them, if the acorns could be secured in sufficient quantities.

The acorns are variable in water content. Some of them contain as high as sixty per cent. water. The two groups into which the acorns are divided on account of their fat content are likewise botanicalljv’ different, one being k11own as the bitter acorns and the other as the sweet acorns. One group of oaks is rich in tannic acid, and the other is low. The acorns were used in digestion experiment No. 104, in connection with corn cobs. Thev were readily eaten bv the sheep. The feedinq value of the acorn will depend largely upon the class of oak from which the acorns are derived, and the extent to which the acorns have dried out before they are gathered. It also depends to some extent on the FEEDING VALUEs or CERTAIN FEEDING Srurrs. 13 amount of Worms present, and the extent of their development, as some lots of acorns received were very rapidly eaten by the worms. The fresh acorns of the red oak group have about eighty-eight per cent. of the value of alfalfa hay, while those of the post oak group have about sixty- five per cent. of the value of alfalfa hay. Alfalfa Hay Three samples of alfalfa hay were used in digestion experiments, two of them being used for the purpose of feeding With other feeding stuffs, a preliminary digestion experiment being made in each case. The al- falfa hay used was somewhat low in protein, and high in fiber. It Was readily eaten by the sheep. Alfalfa hay has about seventy per cent. of the value of Wheat bran. Bear Grass (Yucca Glauca.) Bear grass (Y ucca glauca) Was used in digestion experiment No. 98. The leaves of this grass are very‘ tough and contain small spines along the edge. Although the sheep were fed on a ration not sufficient to maintain them, they ate only about forty per cent. of the bear grass. The bear grass which was eaten was digested about as well as any other hay or forage plants. Bear grass has a productive coefficient that coin- pares favorably with other hays. But the fact that there is a great Waste in feeding this plant, even when chopped up as in our experiments, must be taken into consideration. The plant is very tough when dry. Beet Pulp Dry beet pulp was fed alone in digestion experiment No. 100. It was not eaten well, about fifty per cent. being left by the sheep. It also gave rise to some (ligestion disturbances, or was too laxative in its action. The (llQGSJEQd beet pulp has a productive value about twelve per cent. greater than Wheat bran and about seventy-five per cent. of that of corn chops. Com Cabs Ground corn cobs were fed alone in digestion experiment No. 99, with cottonseed meal in experiment No. 101, and with acorns in ex- periment No. 104. It was not eaten well when fed with acorns, al- though it was eaten well when fed with cottonseed meal. The corn cobs do not contain any digestible protein, but the digesti- bility of the crude fiber and of the nitrogen-free extract compare favor- ably with the digestibility of hays and some other roughages. The feed- i ing value of ground corn cobs is apparently high for feed of this char- acter. and compares favorably with prairie hay. The productive value seems to be higher than that of some varieties of prairie hay. It ap- parently has a value of about eighty-three per cent. of alfalfa hay, and 14 TEXAS AGRICULTURAL EXPERIMENT STATION. 180 per cent. of cottonseed hulls. It seems to be a better feed than has generally been supposed. Cotton Bars Requests for the examination of cotton burs came from several sources. There are accumulations, of cotton burs around every gin, and it is said that cows eat them readily. The cotton burs contain some seed and lint. - In the digestion experiments here reported, the seed and lint was separated from the burs so that thedigestibility is of the burs alone. The burs were fed withialfalfa hay, and were eaten well by one sheep though not by the other. The productive value is about fifty-five per cent. that of alfalfa hay. The feeding value of cotton burs is less than that of prairie hay, but somewhat more than the feed value of cottonseed hulls, apparently about twenty-five per cent. more. Cold-pressed Cottonseed Digestion experiment No. 89 was made with cold-pressed cottonseed made from heated seed. The extraction of the oil from this sample was very poor, and the product contained eighteen per cent. oil. The production coefficients of all the constituents of this sample, with the exception of the oil, is lower than the average for cold-pressed cottonseed. The high contents of fat, of course, add considerably to the feeding value of the particular sample studied. According to the experiment, cold-pressed cottonseed would have about eighty-five per cent. of the product of the same composition made from good seed. There is al- ways danger that poisonous substances will develop when cottonseed heats, though the actual cases of injury seem to be rare. Peanut H ay Peanut hay was used in digestion experiment No. 87. It contained no nuts. It was eaten readily by the sheep, although some residue was left by one of the sheep. According to our experiments, peanut hav has a feeding value of about twenty-eight per cent. more than alfalfa hay and about ninety per cent. of wheat bran. It does not contain quite as much digestible protein as alfalfa but it contains a smaller per- centage of crude fiber, which gives it a better feeding value. Peanut Meal Peanut meal of very high grade was used in digestion experiment No. 96. This peanut meal is of unusually good quality, containing only five per cent. of crude fiber. This means that it contains only a small amount of peanut hulls. The constituents of this peanut meal have a high digestibility. Peanut meal having a larger quantity of hulls would have a correspondingly lower digestibility, and lower feeding value. FEEDING VALUES or CERTAIN FEEDING STUrrs. 15 since the hulls have no value as a feed. This peanut hay has a pro- _ ductive value about ten per cent. greater than corn. Prairi e H ay Prairie hay was used in digestion experiments No. 85 and 86. It contains somewhat more crude fiber than the average Texas prairie hay, and has a lower digestibility and feeding value. There is always waste feeding prairie hay, which is diflicult to take into consideration. Rice Bran Rice bran was used in digestion experiment No. 94, in connection with alfalfa hay. The sample used was of excellent quality and was eaten readily by the sheep. The digestibility of the constituents is close to the average previously found. Rice bran containing twelve per cent. crude “fiber has a productive value about twenty per cent. less than corn. The feeding value varies to some extent, as the percentage of fat is somewhat variable. Rice Hulls Rice hulls were fed together with alfalfa hay in digestion experiment No. 91. The feed was eaten well by one of the sheep, not so well by the other. The production coefficients found in this experiment are close to those found previously. The feeding value of rice hulls is very low, being about forty-eight per cent. of cottonseed hulls and twenty-three per cent. of alfalfa. i Rhodes Grass H ay Rhodes grass hay was used in digestion experiment No. 82. The hay was eaten readily by one of the sheep, but not by the other. The digest- ibility of the hay eaten is quite close to that of the other hay. The productive value of the sample tested is higher than the average for Texas prairie hay, and is equal to alfalfa hay. Soapweed Stem The hard wooden stem of the soapweed, which has been shredded, was fed with cottonseed meal in experiment No. 102. The protein was not well digested, but the digestibility of the nitrogen-free extract is about the same as_ for hays. The productive value is about eighty per cent. that of Texas prairie hay and sixty-seven per cent. of alfalfa hay or forty-five per cent more than cottonseed hulls. The soapweed stem was eaten well by the animals. Spanish. Moss Spanish moss was fed in connection with cottonseed meal in digestion experiment No. 103. It-was eaten well by the animals, and had a 16 TEXAS AGRICULTURAL EXPERIMENT STATION. good digestibility. The productive value of the Spanish moss dried to about nine per cent. water content is about twenty per cent. more than that of alfalfa hay, although it contains no digestible protein. The ' sample used consisted of the green Spanish moss, which was collected and allowed to dry. It is possible that the dry Spanish moss which has died on the trees would have a much lower digestibility. According to this experiment, Spanish moss is Well worth using as a feed if it can be secured at no great expense. The green Spanish moss has a pro- ductive value about ten per cent. more than cottonseed hulls, and about fifty per cent. that of alfalfa hay.
