“…Previous research indicates that raw soybeans (RSB) contain antigrowth factors that retard growth in swine (Robison, 1930;Jimenez et al, 1963;Hooks et al, 1965Hooks et al, , 1967aCombs et al, 1967;Sheppard et al, 1967;Young, 1967Young, , 1969Combs and Wallace, 1969;Jensen et al, 1970Jensen et al, , 1971Young et al, 1970;Hanke et al, 1972;Yen et al, 1974Yen et al, , 1977. Osborne and Mendel (1917) demonstrated that heating RSB destroyed the antigrowth factors.…”

An experiment was conducted to determine the influence of feeding ground raw soybeans to swine during gestation on reproductive performance for three consecutive parities. Sixty crossbred gilts were bred and randomly assigned to two dietary treatments with 30 gilts/treatment. The diets were formulated to contain 14% crude protein with either soybean meal (SBM) or raw soybeans (RSB) serving as the source of supplemental protein. All animals were fed in individual gestation stalls and were given 1.81 kg of feed/d. Upon entering the farrowing house at approximately 110 d of gestation, all animals, regardless of previous treatment, were fed the same lactation diet (15% protein corn-soybean meal diet) until the pigs were weaned (28 d). After completing three parities, 88 of a possible 90 litters were farrowed by each dietary group. Total number of live pigs at parturition and 21 d for three parities were: (SBM) 887, 732 and (RSB) 924, 765, respectively. Average pig birth and 21-d weights for each dietary group were (SBM) 1.52, 5.42 and (RSB) 1.59, 5.41 kg, respectively. Pigs from dams fed RSB had higher average pig birth weights (P less than .05), but weaning weights were not affected. There were no significant differences in maternal weight changes during gestation. Milk samples were collected within 6 h after parturition, 3 and 14 d of lactation. Percentage milk fat for each time period was: (SBM) 5.6, 9.0, 7.0 and (RSB) 6.3, 10.7, 6.5, respectively. Sows fed RSB had a higher milk fat at 3 d (P less than .05) but a lower milk fat at 14 d (P less than .1) than did the sows fed SBM. The study indicated RSB can be effectively utilized in gestation diets fed to swine.
