Abstract

Juvenile turkey hens were actively immunized against vasoactive intestinal peptide (VIP) prior to photostimulation to evaluate its effect on enhancing egg production. VIP antibody titers were generated in the VIP immunized hens and a greater rate of egg production per hen was observed compared to controls. In addition, the first egg laying cycle was extended for an additional 7 wk without a significant decline in egg production. Over a 27-wk period, 116 settable eggs per hen were produced from the VIP immunized hens as compared to 102 and 90 eggs for the keyhole limpet hemocyanin and saline control groups, respectively. Based on the increased egg production and the extension of the first egg laying cycle, this experiment demonstrates that VIP immunization of turkey hens is potentially economically relevant.

摘要

在光刺激前，对幼年母火鸡进行血管活性肠肽（VIP）主动免疫，以评估其对提高产蛋量的影响。VIP免疫的母鸡产生了VIP抗体滴度，与对照组相比，每只母鸡的产蛋率更高。此外，第一个产蛋周期延长了7周，产蛋量没有显著下降。在27周的时间里，VIP免疫的母鸡每只产116枚可孵化蛋，相比之下，钥孔戚血蓝蛋白组和生理盐水对照组每只分别产102枚和90枚蛋。基于产蛋量的增加和第一个产蛋周期的延长，本实验表明对母火鸡进行VIP免疫可能具有经济意义。
