AD3E Fertility Liquid is a specialized vitamin pre-mix designed for cage and exotic birds, including ornamental species and pigeons. This formulation is intended for use before and after mating. Vitamin Benefits: Vitamin E plays a significant role in reproductive health, and its deficiency can lead to decreased sexual instinct and sperm production. Vitamin A supports fertility, while Vitamin D3 regulates calcium-phosphorus metabolism, critical for eggshell formation and embryo development. Administration: Recommended during the mating season and periods of egg-laying, dissolve 5ml per liter of drinking water for 5 consecutive days, with a 10-day break, until the completion of the breeding period.
