“…Convincing evidence has been presented implicating increased prolactin secretion as the cause of reduced circulating gonadotrophins, ovarian regression and the shift from egg laying to the incubation phase of reproductive cycle in the hen (Crisostome et al, 1998). In my study I have observed reduced laying pauses and longer sequences in birds treated with bromocriptine and peppermint orally.…”

Abstract:The study was conducted to determine the effect of antiprolactin drug (Bromergon®) and Peppermint (Mentha piperita L.) on broodiness, laying performance and egg quality in indigenous hens. The effect of modulation of prolactin concentration on egg production, sequence length and inter sequence pauses were studied by analyzing the oviposition records. Total sixty indigenous laying hens (30-40 weeks of age), were assigned for treatment with peppermint solution and Bromergon®. Sixty laying hens were randomly divided into 4 groups (A, B, C and D) and each group remained 15 hens. Group A was kept for control, Group B was treated with bromocriptine (Bromergon® SANDOZ) orally @ 640 μg per bird per day, Group C with 50% peppermint solution @ 10 g per bird orally and Group D was with peppermint and Bromergon® combined at previous dose. Over the course of trial, incremental dietary peppermint (Group C) significantly (p˃0.05) increased egg production, body weight of treated indigenous hens than other groups. Egg shell percentage, thickness and haugh unit of hens fed diets supplemented with peppermint were greater than that of hens fed the control diet. However, peppermint supplementation did not influence other egg quality characteristics like albumen and yolk percentages and albumen height. The treated birds had comparatively longer sequences and fewer pauses. It is concluded that the physiological pauses occur during ovulatory sequences can be disrupted effectively using Bromergon® and peppermint. Prolactin levels modulated which may interfere with follicular recruitment and subsequent oviposition thereby improves egg laying potential of the indigenous hens.

“…Experimental increases in prolactin levels induce the onset of incubation behavior in turkey hens . Moreover, immunization against prolactin or vasoactive-intestinal peptide (VIP) -a hypothalamic releaser of prolactin secretion -resulted in turkey and chicken hens failing to engage in incubation behavior , 1996Crisostomo et al, 1998;Li et al, 2011). Although these findings demonstrate that prolactin is essential to the onset of incubation, elevated prolactin levels and stimuli from the egg do not appear sufficient to induce incubation behavior under some circumstances (Lehrman, 1963;Silver, 1984;Buntin and Tesch, 1985).…”

“…4A). Although this theory has been tested and supported by a few studies El Halawani et al, 1996;Crisostomo et al, 1998;Sockman et al, 2000;Ouyang et al, 2011;but see Williams, 2012;Ryan et al, 2014Ryan et al, , 2015, the influence of stressors on prolactin levels has not been integrated into this theory. To the best of our knowledge, the combined influence of stress on prolactin levels and laying effort has rarely been investigated (but see Rozenboim et al (2004)).…”

This article is part of a Special Issue "Parental Care". In vertebrates, adjustments of physiology and behavior to environmental changes are often mediated by central physiological mechanisms, and more specifically by hormonal mechanisms. As a consequence, these mechanisms are thought to orchestrate life-history decisions in wild vertebrates. For instance, investigating the hormonal regulation of parental behavior is relevant to evaluate how parents modulate their effort according to specific environmental conditions. Surprisingly and despite being classically known as the 'parental hormone', prolactin has been overlooked in birds relative to this context. Our aim is to review evidence that changes in prolactin levels can mediate, at least to some extent, the response of breeding birds to environmental conditions. To do so, we first examine current evidence and limits for the role of prolactin in mediating parental behavior in birds. Second, we emphasize the influence of environmental conditions and stressors on circulating prolactin levels. In addition, we review to what extent prolactin levels are a reliable predictor of breeding success in wild birds. By linking environmental conditions, prolactin regulation, parental behavior, and breeding success, we highlight the potential role of this hormone in mediating parental decisions in birds. Finally, we also review the potential role of prolactin in mediating other life history decisions such as clutch size, re-nesting, and the timing of molt. By evaluating the influence of stressors on circulating prolactin levels during these other life-history decisions, we also raise new hypotheses regarding the potential of the prolactin stress response to regulate the orchestration of the annual cycle when environmental changes occur. To sum up, we show in this review that prolactin regulation has a strong potential to allow ecological physiologists to better understand how individuals adjust their life-history decisions (clutch size, parental behavior, re-nesting, and onset of molt) according to the environmental conditions they encounter and we encourage further research on that topic.

“…Immunization against prolactin or the prolac-tin-releasing-factor vasoactive intestinal peptide (Sharp, Dawson, and Lea, 1998) inhibits incubation (Crisó stomo, Guémené, Garreau-Mills, and Zadworny, 1997;Sharp, 1997a;Crisó stomo, Guémené, Garreau-Mills, Morvan, and Zadworny, 1998). Treatment of females with exogenous prolactin induces incubation if it is preceded by nesting behavior, which is dependent on increased plasma progesterone and estradiol 17-␤ (El Halawani, Silsby, Behnke, and Fehrer, 1986;Sharp, 1997b).…”
