Abstract

Heat stress is a very common type of stress in dairy animals. Exposure to heat-stress can result indecreased yield and poor, watery consistency of milk. Here, the results of an efficacy trial of apolyherbal antistressor premix at reducing summer stress-associated milk yield losses in dairy cows arereported. 12 healthy lactating Gir cows in early to mid of first to third lactations were randomized to oneof two groups. The first group was left unsupplemented while the second group receivedsupplementation with a polyherbal anti-stressor (Stresomix™ premix, M/s Ayurvet Limited, India) forseven days. Daily milk yield was recorded over a 30 days’ period of moderate heat stress (THI = 81.9).Protein and fat content of milk and serum cortisol levels were also measured at specific intervals. Thepolyherbal antistressor-supplemented group T1 showed significant improvements in milk fat content,fat-corrected milk yield, and serum cortisol levels over the untreated control group T0, attesting theefficacy of the polyherbal antistressor supplement in heat-stressed dairy cows. Based on the results of thestudy, the polyherbal antistressor, Stresomix premix, at 1 Kg/tonne of feed for 7 days, was foundefficacious for the reduction of stress and improvement of milk fat content in dairy cows under summerstress.
