Objective: Studying the growth promoting and performance enhancing activity of Stresomix in weaned pigs up to grower stage.12 weaned pigs (Tamworth __ampersandsigntimes; Desi breed) of almost same age group (2-3month) and body weight were procured. All the 12 experimental piglets were randomly divided into 2 groups- group T1 and group T2 maintaining similar male: female ratio (n=6). Each group was allotted to different dietary treatments. Group T1 served as no treatment control group fed with basal ration only and group T2 piglets were supplemented with Stresomix (1kg/tone of feed) (M/S Ayurvet Limited, Baddi, India). Growth and haemato biochemical parameter were studied for 90 days on fortnightly basis. Daily body weight gain and linear body measurements were high in Stresomix supplemented group T2. Feed conversion efficiency was significantly improved in Stresomix supplemented group T2. Haemato biochemical parameters were normal in Stresomix supplemented group T2. Stresomix improved the growth parameters and enhanced the feed efficiency in the piglets.
