Field evaluation of TANUVAS-GRAND: A nutritional intervention to enhance dairy cattle productivity in Sivagangai district, Tamil Nadu

Abstract

A field demonstration was carried out at Battam village in Sivagangai district, Tamil Nadu to assess the efficacy of TANUVAS-GRAND as a feed supplement in dairy cattle. Fifteen crossbred dairy cows traditionally fed with unbalanced gruel-based diets were selected. TANUVAS-GRAND was supplemented for 45 days and parameters including milk yield, dung quality, fertility, respiratory signs, and coat health were assessed. Significant improvements were recorded in milk yield (0.55 L/day to 1.27 L/day), dung consistency, skin texture, and estrus return. The study recommends TANUVAS-GRAND for enhancing rural dairy productivity.
