Study the efficacy of Galactin Vet Bolus on

Galactogogues (or lactogogues) are medications or other substances believed to assist in the initiation, maintenance, or augmentation of maternal milk production. Milk production is a complex physiological process involving physical and emotional factors and the interaction of multiple hormones, the most important of which is believed to be prolactin. During stress milk production reduces. Milk production it self is stress for lactating cows. With parturition and expulsion of the placenta, progesterone falls and a full milk supply (Lactogenesis) is initiated (Neville et al., 1977). Through interaction with the hypothalamus and anterior pituitary, dopamine agonists inhibit, and dopamine antagonists increase prolactin secretion and thereby milk production (endocrine control). Thereafter, prolactin levels gradually decrease but milk supply is maintained or increased by local feedback mechanisms (autocrine control) (Lawrence et al., 1999). Therefore, an increase in prolactin levels is needed to increase, but not maintain, milk supply. The medications used often exert their effects through antagonism of dopamine receptors, resulting in increased prolactin (Gabay, 2004). The objective of the present study is to assess the effect of polynutrient formulation, GALACTIN VET bolus of The Himalaya Drug Company, Bangalore contains powders of Leptadenia reticulata, Asparagus racemosus, Withania somnifera, Arundo donax, Cissampelos pareira, Foeniculum vulgare, and extracts of Eclipta alba and Solanum nigrum on quality and quantity of milk in dairy cows. Study the efficacy of Galactin Vet Bolus on milk yield in dairy cows
