Abstract
Fortification of animals’ diets with antibiotics in promoting the growth and development has increased the public’s concern about the safety of animal products and their adverse effects on human health and natural immunity. The study conducted at Mabilbila Sur, Santa, Ilocos Sur from January 12, 2021 to February 28, 2021. The study determined the best sources (garlic, oregano, turmeric) and levels (2g, 4g, 6g) of natural growth promotants and their interaction as an alternative to antibiotics. It aimed to determine the effects on the growth performance, carcass trait, sensory traits, and economic analysis of red broiler chicken. One hundred eighty (180) experimental birds were distributed into nine treatments (6 chicken/pen) including one floating control replicated thrice in a Strip-Split Plot Design. Supplementation of four grams turmeric infusion resulted to the heaviest chicken thus, higher profit above feed cost. Most efficient feed conversion attained with the supplementation of two grams garlic and oregano.
