Galactogogues are substances used to induce, maintain, and increase milk production, both in human clinical conditions (like noninfectious agalactias and hypogalactias) and in massification of production in the animal dairy industry. This paper aims to report the state of the art on the possible mechanisms of action, effectiveness, and side effects of galactogogues, including potential uses in veterinary and human medicine. The knowledge gaps in veterinary clinical practice use of galactogogues, especially in the standardization of the lactogenic dose in some pure drugs and herbal preparations, are reviewed. 1. Introduction facial seborrhea, and hyperhidrosis, and even sudden death.

The has a direct impact on growth, development, and health in main galactogogue used in cattle is rBST which has reported neonatal period [1]. Breastfeeding is influenced by nutritional adverse health effects that directly affect animal welfare [4, 5]. and nonnutritional factors (associated with endocrinology, Plants with galactogogues components include fenugreek health, climate, and management) that affect milk synthesis (Trigonella graecum foecum), fennel (Foeniculum vulgare), and secretion.
