Abstract
Mineral deficiencies remain one of the major nutritional constraints
affecting the productivity of dairy cattle maintained under smallholder farming
systems in India. Inadequate supplementation of essential macro- and
micro-minerals adversely affects milk production, milk composition,
reproductive performance and overall animal health, thereby reducing farm
profitability. The present study was undertaken to evaluate the effectiveness
of TANUVAS SMART Mineral Mixture as a nutritional intervention for improving
milk yield, milk fat percentage and economic returns in lactating dairy cattle
under field conditions. The study was conducted as a Frontline Demonstration
(FLD) by Krishi Vigyan Kendra, Kundrakudi, Tamil Nadu Veterinary and Animal
Sciences University, at Pillayarpatti village of Sivagangai district, Tamil
Nadu. Ten progressive dairy farmers possessing healthy lactating crossbred cows
were selected, and one cow from each farm was supplemented daily with TANUVAS
SMART Mineral Mixture along with the regular concentrate feed for a period of
90 days. Milk yield, milk fat percentage, feed intake, body condition, general
health and economic returns were recorded before and after supplementation. The
supplementation resulted in a significant improvement in productive
performance. The average daily milk yield increased from 7.50 ± 0.42 L to 8.63
± 0.46 L, representing a 15.07% increase, while milk fat percentage improved
from 3.80 ± 0.18% to 4.20 ± 0.21%. Farmers also reported improved feed intake,
better body condition, enhanced reproductive performance and reduced incidence
of metabolic disorders. Economic analysis indicated an additional income of
approximately ₹3,168 per animal over the 90-day supplementation period after
accounting for the cost of mineral supplementation. The findings demonstrate
that TANUVAS SMART Mineral Mixture is an effective, economical and
farmer-friendly nutritional intervention for enhancing milk production and
profitability under village production systems. Wider dissemination through
Krishi Vigyan Kendras and extension programmes could substantially improve
dairy productivity and strengthen the livelihoods of smallholder farmers.
