Choline versus Betaine and Expeller versus Solvent Soybean Meal for Weanling Pigs

Effect of Level of Protein and Supplemental Choline on Reproductive Performance of Gilts Fed Sorghum Diets

“…(Grandhi and Strain, 1981), did not show any improvement in weaning weight due to increased gestation choline levels. Dietary protein and methionine have been shown to spare completely choline for growth (Nesheim et al, 1949;Dyer and Krider, 1950;Firth et al, 1953;Kroening and Pond, 1967;Bryant et al, 1977;Russett et al, 1979b), and the increase in choline from soybean meal in the high protein diet increased dietary choline (865 vs 1,105 mg/kg for the low and high protein diets, respectively). Our data suggest that the choline effect was more evident in gilts fed a 12% protein diet than gilts fed a 16% protein diet, and that the effect was most evident at 42 d postpartum (table 3).…”

Fat utilization by baby pigs

“…However, there was no significant difference in the average total gain between the pigs fed the solvent soybean meal and the solvent meal plus soybean oil diet. These results are in agreement with the findings of Dyer and Krider (1950) who reported that solvent extracted soybean meals were superior to the expeller soybean meal when rate of gain of the pigs was used as the criterion to estimate nutritive value.…”

“…Soybean nfeal Dyer and Krider (1950) compared the feeding value of the two kinds of solvent extracted soybean meal to that of the expel 1er soybean meal for weanling pigs. Both the solvent soybean meals contained 44 percent protein, one of which was heat treated for 60 minutes at a maximum temperature of 230°F and the other was treated for 30 minutes at 212°F in the presence of steam at atmospheric pressure.…”

Comparison of Solvent Soybean Oil Meals and the Effect of Dried Whey Products and Antibiotics in Drylot Rations for Pigs

“…The three solvent soybean oil meals 6 were equally effective in promoting rate of gain when fed to weanling pigs in drylot rations containing 20% crude protein. Dyer and Krider (1950) have reported that solvent soybean oil meal promoted significantly more rapid gains than expeller soybean oil meal when fed in drylot rations to weanling pigs. The addition of 25 nag.…”
