<br/><br/> The study was conducted to determine the effects of dietary supplementation of <br/>piper betle (Piper siriboa L.) leaf meal (PBLM) in a corn-soya based diet for Class B <br/>Cobb broiler chickens. Specifically, the study aimed to: determine the feed <br/>consumption, gain in weight, feed conversion ratio, feed cost per kilogram gain, weight <br/>of the internal organs, and profitability and performance efficiency factor (PEF) of <br/>broilers. The study was conducted at Sitio Sabi-Sabi East Brgy. 32, Palongpong, City <br/>of Batac, Ilocos Norte from October 4 to November 13, 2023.  A total of 12 cages, <br/>housing nine (9) heads of chicks, served as the experimental units and were randomly <br/>distributed to four treatments with three replications following the Completely <br/>Randomized Design (CRD).  The feeding of the experimental diets at 4 g, 8 g, and 12 <br/>g per kilogram diet inclusion rate was done after the brooding stage.  <br/>Statistical analysis revealed that birds fed with corn-soya-based diets without <br/>and with different levels of PBLM have similar weekly feed consumption and growth <br/>parameters on Class B Cobb broilers.  Likewise, the feed conversion ratio, performance <br/>efficiency factor, total sales, net income, return on investment and weight of the internal <br/>organs were not statistically affected by the addition of PBLM. However, numerically, <br/>birds fed with 12g PBLM had the highest gross income, net income and return on <br/>investment.
