The effects of inclusion in the diet of different sources of soya bean meal (SBM) on growth performance, total tract apparent digestibility (TTAD) and apparent ileal digestibility (AID) of major dietary components and mucosal ileum morphology were studied in Iberian pigs weaned at 30 days of age. From 30 to 51 days of age (phase I), there was a control diet based on regular soya bean meal (R-SB...

Green economy is environmentally friendly economy, which important for the sustainable economic development and environmental protection. Based on panel data of 30 provinces cities in China, a three-stage super-efficient SBM-DEA (slack-based model-data envelopment analysis) model constructed to evaluate efficiency green analyze its regional differences. The results show that, first, random erro...

BACKGROUND One of the emerging techniques for performing the analysis of the DNA microarray data known as biclustering is the search of subsets of genes and conditions which are coherently expressed. These subgroups provide clues about the main biological processes. Until now, different approaches to this problem have been proposed. Most of them use the mean squared residue as quality measure b...

A study was conducted using 63 Angus crossbred heifers (234.5 ± 18.97 kg) to compare Distillers Dried Grains with Solubles (DDGS) versus Soybean Meal (SBM) as a supplemental protein source. Animals were assigned to three treatments, which were SBM and two levels of DDGS, fed as a top-dressed supplement. Treatments were formulated to provide .30 kg SBM (12.5% CP, 1.08 Mcal NEg/kg; SBM), .30 kg D...

An original data envelopment analysis (DEA) model is to evaluate each decision-making unit (DMU) with a set of most favorable weights of performance indices. The efficient DMUs obtained from the original DEA construct an efficient (bestpractice) frontier. The original DEA can be considered to identify good (efficient) performers in the most favorable scenario. For the purpose of identifying bad...

An experiment was conducted to compare nutritional composition of soybean meal (SBM) produced in China, Argentina, Brazil, the U.S., or India and the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of CP and AA in these SBM when fed to growing pigs. Five sources of SBM from China, Argentina, Brazil, and the U.S., and 4 sources from India were collected for a to...

Rough data envelopment analysis (RDEA) evaluates the performance of the decision making units (DMUs) under rough uncertainty assumption. In this paper, new discussion regarding RDEA is extended. The RSBM model is proposed by integrating SBM model and rough set theory. The process of reaching solution is presented and this model is applied to efficiency evaluation of the DMUs with uncertain ...

Two experiments were conducted to determine the concentration of DE and ME and the standardized ileal digestibility (SID) of AA in chicken meal, poultry byproduct meal, hydrolyzed porcine intestines, a spent hen–soybean meal (SBM) mixture, and conventional SBM fed to weanling pigs. In Exp. 1, 48 barrows (initial BW: 14.6 ± 2.2 kg) were placed in metabolism cages and allotted to 6 diets with 8 r...

The objectives of this study were to examine the effects of feeding zinc-treated soybean meal (Zn-SBM) on ruminal fermentation patterns and duodenal AA flows in steers fed diets based on corn silage and corn. Six steers (385 kg) fitted with ruminal, duodenal, and ileal cannulas were used in a replicated 3 x 3 Latin square design experiment with 14-d periods. Diets were supplemented with solvent...
