Intestinal inflammation disrupts energy metabolism in layer pullets: insights into energy partitioning and intestinal metabolomic profiling.

ABSTRACT:

Background

Intestinal inflammation is an energy-consuming process that may alter energy supply and demand in poultry. During inflammation, the intestinal energy metabolic profile and the patterns of energy partitioning remain unclear. This study investigated the effects of intestinal inflammation on energy intake, heat production (HP), retained energy (RE) and intestinal energy metabolites in layer pullets.

Methods

After 7 d dietary adaption, 32 "Jing Tint 6" layer pullets with average body weight (1,123.50 ± 8.55 g) were selected from 96 birds, and randomly assigned to two groups (CON: Control group, INFL: Inflammation group) with 8 replicates per group. Indirect calorimetry analysis was conducted over 7 d to determine HP and fasting HP (FHP). During this period, pullets in
