U.S. Soybean Supply and Soybean Meal Use

The April USDA World Agricultural Supply and Demand Estimates provide an early look at the coming season’s soybean/soybean meal supply and demand estimates. While these values will probably change during the growing season due to weather and market conditions, it would appear that 2017 production of soybeans will be slightly higher this year compared to last year based on the number of acres to be planted and the anticipated soybean yields. USDA economists are also predicting domestic use of soybean meal will also be increased and meal prices will be lower. These estimates indicate that the livestock and poultry producer will have access to an ample supply of soybean meal at a lower price compared to recent years.

Soybean Meal’s Feeding Value Varies with Country of Origin

An experiment was conducted to compare nutritional composition, the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of soybean meals (SBM) produced in various countries. Five sources of SBM from China, Argentina, Brazil, and the U.S., and four meal sources from India were collected, analyzed for nutrients, and included in a cornstarch based diet in which SBM was the only amino acid (AA) contributing ingredient. An N-free diet was also formulated and fed. Twenty-five barrows weighing about 31 kg were equipped with a T-cannula in the distal ileum and randomly allotted to a 25 × 8 Youden square design with 25 diets and 8 feeding periods.

Results indicated the concentration of crude protein was greater (P ‹ 0.05) in SBM from Brazil and India (49.3 and 49.5%, respectively) than in SBM from China, Argentina, or the U.S. (45.1, 46.7, and 47.3%, respectively). The concentration of most indispensable AA followed the same pattern as crude protein with the exception of SBM from the U.S. contained significantly more (P ‹ 0.05) indispensable AA than SBM from China or Argentina. Greater (P ‹ 0.05) AID and SID of crude protein and most AA was observed in the U.S. SBM compared with SBM from Brazil, Argentina, and India. Due to the lower concentration of AA in SBM from China, the digestible AA in SBM from China was less (P ‹ 0.05) than in meal from the U.S. Soybean meal from the U.S. or Brazil had less (P ‹ 0.05) variability in SID values than meals produced in Argentina, China, or India. The researchers concluded that the SID of the soy protein and AA are dependent on the country where the SBM is produced. This difference and the variability within each country should be evaluated when formulating diets for weaning pigs.
