| Popis: | Two experiments evaluated the pure glycerin in broiler chicken diets. Experiment 1 was a metabolism test using total feces sampling method with 96 male chickens aging from 17 to 25 d when animals were fed on two treatments: diet1 = no glycerin and diet2 = 60g/kg of glycerin. The apparent metabolized energy measured 4015 kcal/kg and the apparent metabolized corrected for nitrogen balance was 3911 kcal/kg. Experiment 2 evaluated weight gains, feed intake and feed conversion in 480 chicks at 6, 20 and 34 d old fed on diets with 0, 40, 80 and 120 g/kg of glycerin. The results indicate that pure glycerin in chicken diets, as a source of energy must take into consideration the age of the animals and it may be added up to 120 g/kg, from 20 to 41 d of age. |
