So that the economic feasibility for SPGV and SPGM inclusion in the feeding of piglets could be evaluated, prices of raw materials in the market were retrieved and feed costs per kilogram of body weight gain were calculated, according to Bellaver et al.
Dunnett test was applied to compare the results of control diet with each inclusion level of SPGV and SPGM (SAMPAIO, 1998).
Rates for physical, chemical and energy composition and for SPGV and SPGM glycerin (Table 1) were lower than those by Berenchtein et al.
1]) associated with the use of glycerin vs semipurified glycerin (kg) (Figure 1) showed that SPGV and SPGM had ME equivalent to 3,373 and 2,932 Kcal [kg.
Results of economic analysis (Table 5) showed that in the case of SPGV and SPGM there was no change (p > 0.
