摘要

背景:本研究旨在探讨在种蛋孵化过程中,在正常和激素应激条件下,单独或联合使用发光二极管(LED)绿光对啄食相关激素调节的影响。本研究分为两个实验:第一项实验测试了在正常条件下,LED绿光孵化对Hy-line棕色(低啄表型)和Roman粉色(高啄表型)种蛋啄食相关激素的影响。每个品系的 296 枚卵被分为两组:LED绿光孵化组和黑暗孵化组(对照组),每组包含四个重复(37枚/重复)。第二项实验是评估在激素胁迫条件下单独或与褪黑激素联合使用 LED 绿光孵化对罗曼粉红蛋的影响。总共取了 704 枚罗马粉红蛋,分成四组,每组 176 枚。每组又分为两个子组,即 LED 绿光调节孵化组和黑暗孵化组,每个子组 88 枚蛋,每个子组 4 个重复,每个重复 22 枚蛋。实验分组如下:皮质酮溶液注射组(CI)、皮质酮+褪黑素混合溶液注射组(CMI)、磷酸盐缓冲溶液注射组(PI)和不注射组(UI):第一个实验结果表明,与罗曼粉胚相比,在黑暗培养期间,Hy-Line 棕色胚的血清素激素水平较高,皮质酮激素水平较低。LED绿光孵育明显(P 结论:LED绿光孵育的胚胎中5-羟色胺激素的水平明显高于暗孵育的胚胎:总体而言,LED绿光调节孵化对影响啄食习性的激素有调节作用。此外,在注射 MLT 的同时,它还能协同缓解胚胎的激素压力。因此,LED 绿光孵化是减少家禽啄癖的一种新方法。

Sustainable poultry practices: integrating green light interventions to control pecking in chicken.

Background: The present study aimed to investigate the impact of the light-emitting diode (LED) green light alone or in combination with melatonin on pecking-related hormone regulation during incubation under normal and under hormonal stress conditions in breeder eggs. This study was divided into 2 experiments: In the first experiment effect of LED green light incubation on pecking-related hormones under normal conditions, on Hy-line brown (low pecking phenotype) and Roman pink (high pecking phenotype) eggs were tested. The 296 eggs of each strain were divided into two groups: LED green light incubation and dark incubation (control), each containing four replicates (37 eggs/replicate). The second experiment was conducted to evaluate the effect of LED green light incubation alone or in combination with melatonin under hormonal stress conditions on Roman pink eggs. A total of 704 Roman pink eggs were taken and divided into four groups, each consisting of 176 eggs. Each group was further divided into 2 subgroups, LED green light-regulated incubation and dark incubation with 88 eggs per subgroup, having 4 replicates of 22 eggs each. The groups were as follows: corticosterone solution injection (CI), corticosterone + melatonin mixed solution injection (CMI), Phosphate buffer solution injection (PI), and no injection (UI).

Results: Results of the first experiment revealed a higher level of serotonin hormone and lower corticosterone hormone in Hy-Line brown embryos compared to Roman pink embryos during dark incubation. The LED green light incubation significantly (P < 0.05) increased the level of 5-HT while decreasing the CORT level in Roman pink embryos indicating its regulatory effect on pecking-related hormones. Results of the second experiment showed that LED green light incubation significantly (P < 0.05) alleviated the CORT-induced hyperactivity of plasma 5-HT in Roman pink embryos. Furthermore, Melatonin (MLT) injection and LED green light together significantly (P < 0.05) reduced the hormonal stress caused by corticosterone injection in the eggs.

Conclusions: Overall, the LED green light regulatory incubation demonstrated a regulatory effect on hormones that influence pecking habits. Additionally, when coupled with MLT injection, it synergistically mitigated hormonal stress in the embryos. So, LED green light incubation emerged as a novel method to reduce the damaging pecking habits of poultry birds.
