Objectives : To investigate the increasing effect of veterinary acupuncture (VA) on the eggs-laying rate, we carried out the experiment in old hens.
Methods : Twenty four old hens (ISA Brown; 1,200 - 1,400 g) over 75 weeks old whose eggs-laying rates were under the 50% for recent 15 days were used. In experimental group, VA treatments were performed seven times during 10 days. Unang point at the end of bilateral wing and Migun point at the tail bone were stimulated about 30 seconds by the stainless steel needle (0.3 mmo.d.). In control group, similar manual stress were performed at same frequency. The numbers of laideggs were observed for 26 days after the beginning of treatment. Bloods were sampled two times from wing veins during and after the treatment period and serum concentrations of luteinizing hormone (LH) and Estradiol were detected.
Results : Eggs-laying rates of experimental group (34.29±2.79%) were significantly increased than that of control group (27.56±2.00%, P < 0.05) with the significant increasing of LH serum concentration in experimental group (from 0.77±0.13 IU/I to 1.42±0.22 IU/I, P < 0.05).
Conclusions : Increasing effect of VA treatment on the eggs-laying rate in old hens were proved in this study, and it may be the first prompt on the experimental investigation and development of VA.
