Soybean meal is a major protein source for swine and other monogastric animals. However, soybeans, like other legume seeds, contain anti-nutritional factors. Scientists have been successful in eliminating the principle growth inhibitors in soybeans through physical and chemical processing. However, galactosyl oligosaccharides, i.e., α-galactosides and βgalactomannan, known as flatulence-produci...

The objective of this study was to determine the effect of guanidination, the conversion of dietary lysine to homoarginine, on the apparent ileal digestibilities (AID) of amino acids (AA) from 3 protein sources in diets for pigs. Six barrows, initial body weight of 18±1.5 kg, fitted with a simple T-cannula at the distal ileum, were fed one of three corn starch-based diets that contained 18% cru...

Twenty-eight (8 with ruminal cannulas) lactating Holstein cows were assigned to seven 4 x 4 Latin squares in a 16-wk trial to study the effects on production and ruminal metabolism of feeding differing proportions of rumen-degraded protein (RDP) from soybean meal and urea. Diets contained [dry matter (DM) basis] 40% corn silage, 15% alfalfa silage, 28 to 30% high-moisture corn, plus varying lev...

Inedible egg product was evaluated as a replacement for soybean meal and soybean oil in diets fed to weanling pigs. Increasing egg product concentrations of 0, 3, 6, and 9% linearly decreased average daily gain and gain:feed ratio, but not average daily feed intake.

One hundred seventy pigs averaging 21 +/- 1 d of age (initially 5.4 and 5.8 kg, respectively) were used in each of two experiments to determine the effect that further heat processing by moist extrusion has on the nutritional value of soybean products fed to the early-weaned pig (d 0 to 14 postweaning). The experiments were designed as randomized complete blocks with treatments arranged as a 2 ...

The effect of soybean meal, feather meal and hair meal on dry matter (DM), energy and nitrogen (N) utilization by growing steers was evaluated in three metabolism studies. Feather meal (FM) and hair meal (HM) protein were substituted for 25, 50 and 75% (Exp. 1, 2 and 3, respectively) of the soybean meal (SBM) protein in pelleted protein supplements and fed in whole-shelled, corn-ground corncob ...

The objective of this experiment was to determine whether the digestibility of CP and AA in a mixed diet fed to growing pigs is better predicted when based on standardized ileal digestibility coefficients (SID) or apparent ileal digestibility coefficients (AID). Eight growing pigs (initial BW = 92.1 +/- 3.19 kg) were surgically equipped with a T-cannula in the distal ileum and arranged in an 8 ...

The suitability of fermented pigeon pea meal as a protein ingredient in diets for Clarias gariepinus fingerlings was evaluated. A strain of Rhizopus oligoporus was used to ferment the meal for six days at 37°C. Five isonitrogenous (30% crude protein) and isoenergetic (16.45 MJ/kg) diets were formulated in which fermented meal was used to replace soybean meal at five inclusion levels (0%, 25%, 5...

BACKGROUND Dietary ferritin, a protein cage around an iron mineral, is an underestimated source of bioavailable iron. Plant ferritin, the most common dietary ferritin, has not been studied. Iron from animal ferritin is absorbed as well as is iron from FeSO4 in women. OBJECTIVE The objective was to examine iron absorption from purified soybean ferritin. DESIGN Healthy, nonanemic women (n = 1...
