A Universidad Nacional de Colombia study evaluated the effect of the inclusion level of crude glycerin in the diet of growing pigs on growth performance, carcass characteristics and meat quality. A crude glycerin with the following composition (3696 kcal GE/kg, 3579 kcal ME/kg, 8.3% moisture, 82.0% glycerol, 0.79% crude fat, 1.21% sodium and 16 ppm of methanol) was used to formulate isocaloric and isoprotein diets for growing/finishing pigs. A total of 36 pigs weighing about 23 kg were randomly assigned to treatments containing 0, 5 or 10% crude glycerin. Results showed that crude glycerin inclusion did not affect (P >0.05) growth performance (ADG 848 ± 42 g; ADFI 2361 ± 139 g; feed conversion 2.79 ± 0.2 g/g), carcass characteristics and/or meat quality. The researchers concluded that crude glycerin inclusion can be used up to 10%, without adversely affecting the performance of growing pigs.
