Abstract
Feed costs account for approximately 60 to 70% of the cost of poultry farming, and feed utilization is closely related to the profitability of the poultry industry. To understand the causes of the differences in feeding in Shan Partridge ducks, we compared the hypothalamus transcriptome profiles of 2 groups of ducks using RNA-seq. The 2 groups were: 1) low-residual feed intake (LRFI) group with low feed intake but high feed efficiency, and 2) high-residual feed intake (HRFI) group with high feed intake but low feed efficiency. We found 78 DEGs were enriched in 9 differential Kyoto Encyclopedia of Genes and Genome (KEGG) pathways, including neuroactive ligand-receptor interaction, GABAergic synapse, nitrogen metabolism, cAMP signaling pathway, calcium signaling pathway, nitrogen metabolism, tyrosine metabolism, ovarian steroidogenesis, and gluconeogenesis. To further identify core genes among the 78 DEGs, we performed protein-protein interaction and coexpression network analyses. After comprehensive analysis and experimental validation, 4 core genes, namely, glucagon (GCG), cholecystokinin (CCK), gamma-aminobutyric acid type A receptor subunit delta (GABRD), and gamma-aminobutyric acid type A receptor subunit beta1 (GABRB1), were identified as potential core genes responsible for the difference in residual feeding intake between the 2 breeds. We also investigated the level of cholecystokinin (CCK), neuropeptide Y (NPY), peptide YY (PYY), ghrelin, and glucagon-like peptide1 (GLP-1) hormones in the sera of Shan Partridge ducks at different feeding levels and found that there was a difference between the 2 groups with respect to GLP-1 and NPY levels. The findings will serve as a reference for future research on the feeding efficiency of Shan Partridge ducks and assist in promoting their genetic breeding.

Abstract
OBJECTIVE The present study was designed to examine the role of central γ-Aminobutyric acidA receptors and dopaminergic system on feeding behaviour in neonatal layer-type chicken. METHODS In this study, six experiments were designed, each with four treatment groups (n = 44 in each experiment). In experiment 1, four groups of 3-h food-deprived chicks received a dose of either the intracerebroventricular injection of (1) control solution, (2) Levo-dihydroxyphenylalanine as precursor of dopamine; 125 nmol, (3) Gaboxadol (γ-Aminobutyric acidA receptor agonist, 0.2 µg) and (4) Levo-dihydroxyphenylalanine (125 nmol) plus Gaboxadol (0.2 µg). Experiments 2-6 were similar to experiment 1, except that the chickens were intracerebroventricular-injected with 6-hydroxydopamine (is a neurotoxin; 2.5 nmol), SCH23390 (D1 receptor antagonist, 5 nmol), AMI-193 (D2 receptor antagonist, 5 nmol), NGB2904 (D3 receptor antagonist, 6.4 nmol) and L-741,742 (D4 receptor antagonist, 6 nmol) instead of levo-dihydroxyphenylalanine. Then, the cumulative food intake was measured until 120 min post-injection. RESULTS According to the results, intracerebroventricular injection of Gaboxadol (0.2 µg) significantly increased the food intake (P < 0.05). Co-injection of the 6-hydroxydopamine + Gaboxadol significantly amplified the food intake (P < 0.05). Intracerebroventricular injection of SCH23390 (5 nmol) + Gaboxadol (0.2 µg) significantly amplified the Gaboxadol-induced hyperphagia (P < 0.05). No significant effect was observed by co-injection of the D2-D4 receptor antagonists + Gaboxadol (P > 0.05). CONCLUSION These results suggested the interconnection between central Dopaminergic and γ-Aminobutyric acidA on the feeding behaviour mediates via D1 and γ-Aminobutyric acidA receptors in 3-h food-deprived neonatal layer-type chicken.
