Abstract: In dairy cattle, nutrient requirements are vital for controlling immune responses, biological systems, health, lactation and reproductive function. Thus, the goal of the current study was to evaluate how feed supplement (minerals, vitamins and amino acid) supplementation in feed affected milk production, reproductive performance and financial viability of dairy animals during a 100-day span. Experimental animals were selected from five farmers of Chandauli district of Uttar Pradesh. Ten lactating crossbred cattle (N=10) were divided into two groups (5 cows per group): a control group, which received no supplementation and a treatment group, which received a daily 50 g feed supplement per cow along with a subcutaneous administration of 1% Ivermectin solution at a dose of 200 µg/kg body weight (repeated after 3 weeks). The study's findings showed a significantly (p<0.05) increase in milk output of 2.0 liters per day (20%), as well as improvements in reproductive performance and benefit cost ratio. Thus feed supplements (Minerals, Vitamins and amino acid) in the diet of dairy cattle gave better results in improving milk yield and reproductive efficiency for sustainability livelihood in smallholders’ dairy farming.
