Effects of magnesium hydride (MGH) and coated-magnesium hydride (CMG) on the pH, levels of N-NH3 and lactic acid, dry matter degradability in the culture of in vitro fermentation using cecal inocula from broilers (n = 5).
Item | CON1 | MGH2 | CMG3 | SEM4 | p-Value |
---|---|---|---|---|---|
pH | 5.73c | 5.99a | 5.88b | 0.11 | <0.001 |
In vitro dry matter digestibility (%) | 86.62a | 87.35a | 83.75b | 0.40 | <0.001 |
Lactic acid (mmol/L) | 1.12b | 1.18b | 1.43a | 0.05 | 0.004 |
N-NH3 (mmol/L) | 11.19a | 10.16b | 11.05a | 0.17 | 0.016 |
Means within a row, with no common superscript (a, b, c), differed significantly (P < 0.05). 1CON, the control group, cecal content and feed. 2MGH, the magnesium hydride group, cecal content, feed and 200 mg/l of MgH2. 3CMG, the coated-magnesium hydride group, cecal content, feed and 400 mg/l of coated MgH2. 4SEM, standard error of the mean.
