This study aimed to investigate the impact of herbal feed additives, specifically amla (Emblica officinalis) and giloy (Tinospora cordifolia), on the biometrical measurements of Magra lambs in a semi-intensive management system. The experiment was performed on twenty-eight magra lambs of three to four months of age under the semi-intensive system, which were randomly distributed into four experimental groups of seven lambs in each group in a randomized block design (RBD). Herbal feed additive Amla (Emblica officinalis) fruit powder with seed and Giloy (Tinospora cordifolia) stem powder were supplemented at level of 1.5g/kg body weight with concentrate as oral/feed supplemented in T1 and T2 group, respectively except control group and T3 in semi-intensive management system. Group T3was supplemented with the combination of Amla (Emblica officinalis) fruit powder and Giloy (Tinospora cordifolia) stem powder at the level of 0.75g/kg body weight with concentrate as oral/feed. At the end of experiment, significant changes were found in heart girth, abdominal girth, body length and body height though; they were within normal body measurement range. At the end of experiment it appears that incorporation of 1.5g/kg body weight giloy stem powder can be used as a part of the strategy as it is effective to improve morphometric parameters in lambs in the semi-intensive system of arid zone of Rajasthan.

Based on the findings, it can be inferred that the incorporation of the herbal feed additives Amla (Emblica officinalis) and Giloy (Tinospora cordifolia) into the diets of Magra lambs under semi-intensive management significantly impacted the morphometric parameters of the lambs.
