Abstract

In this study, an open respiratory calorimeter for poultry was used for energy metabolism test, and the apparent metabolic energy and net energy of different types of corn in the laying hens' diet were determined by indirect calorimetry combined with substitution method. A total of 180 Hy-Line brown layers at the age of 34 weeks were randomly divided into 6 groups with 30 chickens in each group. The diets to be tested consisted of 5 corn varieties (3 normal corn harvested in October 2018 and 2 aged corn harvested and stored for 3 years in 2016), which were substituted for the basal diet by 50% respectively. The chickens were kept in a cage in the house. The pre-test period lasted for 7 days and the forward test period lasted for 27 days. The forward test period was divided into 3 phases, each of which lasted for 9 days (3 days for adaptation, 3 days for respiratory heat measurement and 3 days for fasting heat measurement). In each phase of the experiment, 4 chickens from each group were selected, weighed and put into 12 metabolic chambers (2 chickens for each metabolic chamber) of the respiratory calorimeter, and each 2 metabolic chambers was fed a kind of diet. The total amount of gas exchange and feces was measured, and the digestion and metabolism test was conducted while the respiration and heat were measured. The results showed that, compared with the basal diet, the apparent metabolic energy of the 5 corn diets under test was significantly increased (P<0.05), and the net energy of the 3 normal corn diets under test was significantly higher than that of the basal diet and 2 aged corn diets under test (P<0.05). The apparent metabolic energy and net energy of the 2 aged corn were significantly lower than those of the 3 normal corn (P<0.05). In this experiment, the apparent metabolic energy of 3 normal corn is 16.19, 15.85 and 16.17 MJ/kg, and that of 2 aged corn is 15.12 and 15.06 MJ/kg, respectively. The net energy of 3 normal corn is 12.39, 12.57 and 12.25 MJ/kg, and that of 2 aged corn is 11.29 and 12.05 MJ/kg, respectively.
