Effects of dietary addition of piper betle (Piper siriboa L.) leaf meal on the growth performance and weight of internal organs of class B broilers / Ralph Christian P. Rarangol City of Batac : MMSU, 2024. xiv, 66 leaves : 29 cm. Thesis (BS in Agriculture major in Animal Science) -- Mariano Marcos State University-College of Agriculture, Food and Sustainable Development, Batac City Bibliography : leaves 36-38 The study was conducted to determine the effects of dietary supplementation of piper betle (Piper siriboa L.) leaf meal (PBLM) in a corn-soya based diet for Class B Cobb broiler chickens. Specifically, the study aimed to: determine the feed consumption, gain in weight, feed conversion ratio, feed cost per kilogram gain, weight of the internal organs, and profitability and performance efficiency factor (PEF) of broilers. The study was conducted at Sitio Sabi-Sabi East Brgy. 32, Palongpong, City of Batac, Ilocos Norte from October 4 to November 13, 2023. A total of 12 cages, housing nine (9) heads of chicks, served as the experimental units and were randomly distributed to four treatments with three replications following the Completely Randomized Design (CRD). The feeding of the experimental diets at 4 g, 8 g, and 12 g per kilogram diet inclusion rate was done after the brooding stage. Statistical analysis revealed that birds fed with corn-soya-based diets without and with different levels of PBLM have similar weekly feed consumption and growth parameters on Class B Cobb broilers. Likewise, the feed conversion ratio, performance efficiency factor, total sales, net income, return on investment and weight of the internal organs were not statistically affected by the addition of PBLM. However, numerically, birds fed with 12g PBLM had the highest gross income, net income and return on investment. lcc THEDIS 24303 24303 0 0 lcc 0 0 MMSU_MAIN MMSU_MAIN THESES 2024-12-10 7488 0 UTHESIS-7488 2024-12-10 2024-12-10 THEDIS Room Use Only
