Purdue University Agricultural Experiment Station Lafayette, Indiana Mimeo A.S. 256 August, 1959 50$ PROTEIN SOYBEAN MEAL IN 32, 36 and 1+0$ SUPPLEMENTS WITH AND WITHOUT TEREPHTHALIC ACID J. H. Conrad and W. M. Beeson Department of Animal Science Fifty percent protein soybean meal is higher in protein and lower in fiber than the more commonly used 1+1+$ soybean meal. This meal, also referred to as dehulled soybean meal, is being used extensively in pig starter rations and broiler rations. In this experiment, protein supplements with three levels of protein were formulated by using different proportions of 50$ protein soybean meal and 12$ protein soybean mill feed (the soybean hulls which are removed in the manufacturer of the 50$ meal). Terephthalic acid (TPA) was added to three lots in this experiment, since it has recently been reported that blood levels of antibiotics are increased by the simultaneous feeding of TPA. The objectives of this experiment were as follows: (1) to compare protein supplements containing 32, 36 and **0$ protein. (2) to study the effect of terephthalic acid on increasing the antibiotic response. , Experimental Procedure Sixty-six Duroc weanling pigs, averaging 27 pounds, were allotted equally to six concrete paved lots. Each group of 11 pigs was confined to a 30 x 1+0 foot concrete slab and provided with a 10 x 12 foot Pur-Dual hog house. Shelled corn and a protein concentrate were fed free choice. Experimental treatments were as follows: Lot 1 - 32$ Protein supplement. Lot 2 - 32$ Protein supplement + 2.5$ TPA. Lot 3 - 36$ Protein supplement. Lot k - 36$ Protein supplement + 2.5$ TPA. Lot 5 - 1+0$ Protein supplement. Lot 6 - 1+0$ Protein supplement + 2.5$ TPA. Details of the protein supplements fed are given in Table 1. Summary of Results 1. Terephthalic acid (an antibiotic potentiating agent) increased gains an average of l+$ (1.1+9 vs. 1.55) and saved seven pounds (2$) of feed required per 100 pounds of gain. The difference in gains was not statistically significant. The terephthalic acid was added at the level of 2.5$ to three different protein supplements which contained 50 grams of aureomycin per ton. For details of results see Table 1+. The aureomycin in this experiment was furnished by American Cyanamid Co., Pearl River New York; 50$ protein soybean meal by Archer-Daniels-Midland, Minneapolis, Minnesota; and the terephthalic acid by E.I. DuPont Co., Wilmington, Delaware.
