Results showed no significant differences in in vitro protein digestibility among the experimental feeds; however, apparent digestibility coefficients
of protein varied, revealing significant differences among treatments.
This may explain the low CP, as well as the low digestibility coefficients
observed during these two seasons.
ANOVA showed that specific growth rate, food consumption, and feed efficiency were significantly affected by salinity, temperature, and the interaction between salinity and temperature, whereas apparent digestibility coefficient
was only affected by temperature.

The digestibility coefficient
for DM, CP, CF, and GE (Table 4) found in the present experiment were generally in the ranges of 55.
In current study, we also detected the apparent ileal CP digestibility coefficient
, N retention, IDE, AME and AMEn could be influenced by the interaction of maize sourcexenzyme.
In addition, DM, CP and GE apparent digestibility coefficients
, as well as digestible protein (DP), digestible energy (DE) and metabolizable energy (ME) content values from M.
05) for most of the components and the reduction in the FDN digestibility coefficient
with the addition of CaO to the sugar cane strongly suggest that the chemical treatment does not achieve its maximum efficiency in all situations.
However, the digestibility coefficients
of the protein was low (Table 2).

Table 4 shows that the apparent nutrient digestibility coefficients
of all the nutrients measured were significantly (P<0.
The digestibility coefficients
of dry matter, cellulose, and energy were higher in summer than fall; 69, 57.
The higher digestibility coefficients
in lipid-supplemented animals can be attributed the fact that nonfatty acids lipids in the diet (likely approximately 1% of DM) are relatively indigestible, and diluting this fraction (waxes, etc.
2012), it is clear that, when phytase influences AA digestibility coefficients
, it does not do so to the same extent for all AA.
The SFSM with the highest concentration of CP (source 9) had greater digestibility coefficients
than the other SFSM for most AA (p < 0.
