Abstract

Neuropeptide Y (NPY) plays a pivotal role in food intake and body weight regulation in both birds and mammals. Unlike imported broilers and layers, native Thai chicken, a tropical non-seasonal breeding species, has lower body weight and exhibits strongly maternal behaviors which, in turn, affect feeding behavior during the reproductive cycle. The aim of this study was to investigate the role(s) of NPY that might be associated with the reproductive cycle of female native Thai chickens using immunohistochemistry technique. The distributions of NPY-immunoreactive (-ir) neurons and fibers in the brain of laying and fasted chickens was also elucidated. Changes in body weight and number of NPY-ir neurons in the nucleus paraventricularis magnocellularis (PVN) were compared across reproductive stages. The results revealed that NPY-ir neurons and fibers were distributed throughout the brain with the greatest density located in the PVN. Differences in the number of NPY-ir neurons in the PVN were found across reproductive stages. The numbers were lowest in non-egg laying and egg laying stages and significantly higher during egg-incubating and chick-rearing stages. Changes in body weight were inversely related to the number of NPY-ir neurons across reproductive stages. In addition, food restriction caused an increase in NPY immunoreactivity, confirming the role of NPY in response to food restriction. Taken together, the present findings suggest that the NPYergic system in the PVN plays an important role in the regulation of food intake during the reproductive cycle in this non-seasonal breeding tropical species.

Abstract

The regulation of avian prolactin (PRL) secretion and PRL gene expression is influenced by hypothalamic vasoactive intestinal peptide (VIP), the PRL-releasing factor in avian species. Recent evidence indicates that D[sub 1] and D[sub 2] dopamine (DA) receptors play a pivotal role in VIP and PRL secretion. The differential expression of DA receptors located on hypothalamic VIP neurons and anterior pituitary cells may affect the degree of prolactinemia observed during the turkey reproductive cycle. The relative expression of D[sub 1D] and D[sub 2] DA receptor subtype mRNA was quantitated using in situ hybridization histochemistry (ISH). D[sub 1D] and D[sub 2] DA receptor mRNA was found expressed throughout the hypothalamus and pituitary. The expression of D[sub 1D] DA receptor mRNA in the hypothalamus was found to be 6.8-fold greater than that of D[sub 2] DA receptor mRNA. Higher D[sub 1D] DA receptor mRNA content was found in the anterior hypothalamus (3.6-fold), the ventromedial nucleus (2.0-fold), the infundibular nuclear complex (INF; 1.9-fold), and the medial preoptic nucleus (1.5-fold) of laying hens as compared to that of reproductively quiescent non-photostimulated hens. The levels seen in incubating hyperprolactinemic hens were essentially the same as in laying hens, except for the INF where levels were 52% higher. During the photorefractory stage (hypoprolactinemia), the D[sub 1D] DA receptor mRNA was at its lowest level in all areas tested. No differences were observed in hypothalamic D[sub 2] DA receptor mRNA abundance throughout the reproductive cycle, except for an increase in D[sub 2] DA receptor mRNA within the INF of photorefractory hens. Also, a marked reduction in D[sub 2] DA receptor mRNA was observed in the pituitary of incubating hens. Pituitary D[sub 1D] DA receptor levels did not change when birds entered the incubating phase. Double ISH revealed that D[sub 1D] and D[sub 2] DA receptor mRNAs were co-expressed within neurons expressing VIP mRNA, predominantly within the lateral hypothalamus and INF. D[sub 1D] DA receptor mRNA was more highly expressed than D[sub 2] DA receptor mRNA. The present findings clearly demonstrate that the expression of stimulatory D[sub 1] DA receptor mRNA in the hypothalamus increases in hyperprolactinemic incubating hens, whereas inhibitory D[sub 2] DA receptor mRNA increases in the pituitary of hypoprolactinemic photorefractory hens.Copyright © 2003 S.
