Abstract Dietary magnesium (Mg) is essential to bone mineralization. Supplemental Mg is typically not considered in commercial swine diets by assuming high bioavailability of Mg from bulky feed ingredients such as corn grain. The objectives of this study were to determine true ileal and fecal digestibility and the endogenous losses of Mg associated with corn in growing pigs by the regression analysis technique. A total of 48 barrows, with an average initial body weight (BW) 32 kg, were randomly assigned to 6 grower pig diets and were fed close to ad libitum for 10 d, with 8-d adaptation and 2-d collection fecal and the terminal ileal digesta samples, according to a randomized complete block design. Six cornstarch-based diets, containing 6 levels of Mg at 0.22, 0.32, 0.38, 0.51, 0.71 and 0.79 g/kg dry matter intake (DMI) of diets, were formulated from corn. There were linear relationships (P < 0.05), expressed as g/kg DMI, between the ileal and fecal outputs of Mg and the total intake of dietary Mg, suggesting that true ileal and fecal Mg indigestibility values (94.8±12.5 vs. 89.2±17.7%); and the ileal and fecal endogenous Mg outputs (0.16±0.02 vs. 0.21±0.11, g/kg DMI of diets) associated with corn could be estimated by the regression analysis. Our results have shown that Mg associated with conventional corn grain was very poorly digested and the gastrointestinal endogenous fecal loss of Mg was significant in the grower pig. Thus, Mg bioavailability in feeds for pigs should be assessed and supplemental of Mg may be warranted in swine diet formulation.

Methodological Considerations

Abstract It is of important methodological considerations to understand how the small intestine would respond to feeding of a series of assay diets deficient in gradient levels of phosphorus (Pi) associated with corn in growing pigs by the regression analysis technique (TRAT). A total of 48 barrows, with an average initial BW 32 kg, were randomly assigned to 6 grower pig diets and were fed close to ad libitum for 10 d, with 8-d adaptation and 2-d collection fecal samples, according to a randomized complete block design. Six cornstarch-based diets, containing 6 levels of Pi at 1.3, 1.9, 2.0, 3.6, 3.4 and 4.0 g/kg DMI, were formulated from corn. The gut permeability marker of D-mannitol was fed 0.30 g/kg BW at 4 h, prior to be sacrificed for sampling. ADG and the apparent ileal DM digestibility were linearly affected (P < 0.05); however, the ADFI, feed conversion ratio, the apparent fecal DM digestibility, transcellular gut permeability and the jejunal alkaline phosphatase kinetics were not affected (P > 0.05) by the increasing dietary levels of corn inclusion. There were linear relationships (P < 0.05), expressed as g/kg DMI, between the apparent ileal and fecal digestible Pi and the total intake of dietary Pi, suggesting that true ileal and fecal Pi digestibility (33.3±4.7 vs. 52.7±3.8%); and the endogenous Pi outputs (0.37±0.12 vs. 0.60±0.09, g/kg DMI) associated with corn could be estimated by the TRAT. Our results have shown that the intestinal physiological functions were not affected in the grower pigs fed on a series of test diets that were deficient in gradient levels of multiple assay nutrients, including macro-minerals, crude protein and amino acids supplied from the testing corn, for a period of 10 d, in the determination of corn-specific true digestibility and the endogenous outputs of Pi by the TRAT.

Time Budget Pressure

This study aims to determine the effect of time budget pressure (TBP) and professionalism on audit quality with auditor experience and job satisfaction as moderating in KAP in Bali. The population in this study were all auditors who worked in KAP in Bali, amounting to 77 auditors. Determination of samples in this study using non probability sampling method with purposive sampling technique. The sample amounted to 42 auditors. The results of this research questionnaire were measured using a Likert scale. The data analysis technique used is Moderated Regression Analysis. The results of this study indicate that time budget pressure has a negative and significant effect on audit quality; professionalism has a positive and significant effect on audit quality; auditor experience weakens the effect of time budget pressure on audit quality, and strengthens the influence of professionalism on audit quality; and job satisfaction weakens the effect of time budget pressure on audit quality, and strengthens the influence of professionalism on audit quality. Keywords: time budget pressure, professionalism, auditor experience, job satisfaction, audit quality

The purpose of this study is to determine the effect of Earning Per Share (EPS) and Debt to Equity Ratio (DER) on stock prices either partially or simultaneously in manufacturing companies in the consumer goods industry sub-sector of food and beverages. This study uses a quantitative approach with secondary data in the form of Earning Per Share (EPS) and Debt to Equity Ratio (DER) data and stock prices. Determination of the sample in this study was using purposive sampling technique with 3 criterias in order to obtain 9 companies from 29 companies. The analysis technique used is panel data regression analysis technique using the help of the Eviews10 application. The results of data processing show that the data is normally distributed after data transformation and there are no symptoms of classical assumptions in the study. The conclusion obtained in the research shows that Earning Per Share (EPS) partially has a positive and significant effect on stock prices. Debt to Equity Ratio (DER) partially has no effect on stock prices. Earning Per Share (EPS) and Debt to Equity Ratio (DER) simultaneously have a positive and significant effect on stock prices

Abstract There is limited knowledge regarding trace mineral bioavailability in trace mineral supplements and common feed ingredients and trace mineral endogenous losses in pigs. The objectives of this study were to investigate intestinal responses and to determine true total tract trace mineral digestibility and the endogenous losses of trace minerals associated with corn and SBM based diets in weanling pigs by the regression analysis. Twenty-four crossbred barrows, with an average initial BW of 14 kg, were randomly assigned to 4 weanling pig diets with inclusion of titanium dioxide (0.30%) and a commercial trace mineral-vitamin premix at 0.125, 0.250, 0.375 and 0.500%, respectively, to result in 4 graded dietary levels of Cu, Zn, Fe, Mn and Se. The pigs were fed close to ad libitum for 11 d according to a randomized complete block design. The dietary inclusion did not affect (P > 0.05) growth performances, ileal and fecal DM digestibility, D-mannitol gut permeability and jejunal alkaline phosphatase kinetics. With the regression analysis, true total tract Cu, Zn, Fe, Mn and Se digestibility values (±SE; n = 23 or 24; P < 0.05) in the trace mineral-vitamin premix were determined to be 137.3±27.9, 40.5±15.4, 66.2±24.6, 94.3±21.6 and 96.6±2.8% vs. the corresponding values in the four weanling pig diets for Cu at 137.4±3.2, Zn at 40.4±3.1, Fe at 66.2±3.0, Mn at 94.2±3.8and Se at 96.2±0.8%, respectively. The total tract endogenous Cu, Zn, Fe, Mn and Se outputs (±SE)associated with the weanling pig diets were also determined (23.4±0.6, 9.2±2.7, 37.2±3.5, 19.4±1.0 and 0.07±0.003 mg/kg DMI diets; n = 23 or 24;P < 0.05). Our results have shown that the intestinal physiological functions and performances were not significantly affected in the weanling pigs fed on the diets with reduced gradient levels of a trace mineral-vitamin premix. Total tract true digestible trace mineral supply should be considered in swine diet formulation.
