Abstract

Nutritional management plays a vital role in the productivity and health of Friesian Holstein (FH) dairy cows. Their diet primarily consists of forage, supported by concentrates and supplements to boost growth, milk yield, and prevent metabolic issues. Mung bean sprouts, rich in protein, are being explored as a potential feed additive. This study assessed the impact of mung bean sprout supplementation on blood biochemistry and liver function in FH cows. Sixteen lactating cows (4-5 years old, ~500 kg) were divided into four groups: T0 (0 g), T1 (500 g), T2 (1000 g), and T3 (1500 g), using a completely randomized design. Blood glucose, urea, and liver enzymes (ALT and AST) were measured. Results showed that 500 g supplementation (T1) significantly increased blood urea (p < 0.01), indicating enhanced protein metabolism, while glucose and liver enzyme levels remained unaffected (p > 0.05). These findings suggest that adding 5% mung bean sprouts to the diet can improve protein utilization without harming liver function or overall metabolism, making it a promising and safe dietary supplement for dairy cows.
