effect of processing of sorghum stover based diets on performance, values of haematological and biochemical parameters and immune response in growing nellore lamb

a complete diet (total mixed ration) with sorghum stover (40%) as sole roughage source was prepared and offered to animals under two forms: as mash or as expanded-extruded pellets (eep). these two complete diets were compared with a conventional diet (ad libitum chopped sorghum stover fed separately with concentrate mixture to meet 80% of protein requirements). these three diets were randomly allotted to 30 male lambs for a period of 150 days. the lambs on conventional, mash and pelleted diet grew with an average daily gain of 62.5g, 78.5g and 101.3g, respectively, with superiority (p
