Research Advances of Effects of Photoperiod on Hormone Secretion,Production Performance and Reproductive Performance of Ruminants
Photoperiod refers to the alternating length of light period and dark period in the daily cycle,which has an important effect on the law of life activities for animals,plants and humans after interacting with differ-ent types and colors of light.China is a country with a vast territory and there are obvious differences in light duration between the north and the south.Combining these photoperiod differences are applied to production in combination with modern farming technology and climate changes,it is of great significance to promote the cost saving and efficiency of livestock breeding and the production of high-quality livestock products.This pa-per focused on the effects of photoperiod on ruminants,mainly reviewed the effects of photoperiod on hormone secretion,production performance(growth performance,meat quality and lactation performance),reproduc-tive performance and behavior of ruminants,and further analyzed the comprehensive effects of photoperiod on ruminants through comparing the relevant research results,in order to provide guidance for the application of photoperiod in the actual production of ruminants.[Chinese Journal of Animal Nutrition,2024,36(5):2721-2727]
