Effect of Nutritional Supplements of Fermented and Unfermented Betel Nutshell Waste in Performance of Broiler Chickens.

Abstract

An experiment was conducted to see the broiler's performance fed with fermented and unfermented betel nutshell. Harvesting betel nut seed leaved peel as a waste that contains some nutrients and active ingredients. This waste was useful for poultry feed, to maintain poultry performance and to reduce cholesterol. The aim of this research was to fermented betel nutshell waste with indigenous microorganism from a vegetable waste mixture that produced cellulase to reduce their crude fiber before feeding to the broiler. The nutrient profile and metabolizable energy of fermented betel nutshell in dry matter basis showed 15.96 % water, 84.04 % dry matter, 23.69 % crude fiber, 10.39 % crude protein, 0.31 % crude fat, 2.60% calcium, 1.26 % phosphorus, and 1360,44 kcal/kg. In this experiment betel nutshell waste from a local farmer in Indonesia, and 80 birds from the broiler strain CP 707 from Charoen Pockphand were used. The experiment was conducted in a completely randomized design with different levels of fermented betel nutshell waste (0, 2, 4, and 6%) and 6 % of unfermented of betel nutshell waste in the broiler ration. Each treatment was repeated four times. The measured values included daily feed intake, daily weight gain, feed conversion, body weight, carcass content, abdominal fat pads, lipoprotein profile (total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) in serum of broiler chikens. The results indicated that fermented betel nutshell waste significantly increased daily feed intake, daily body weight gain, carcass content, and decreased abdominal fat pad, total cholesterol, HDL, and LDL of broiler chickens, however did not affect the feed conversion. The fermentation of betel nutshell waste with indigenous microorganism from vegetable waste mixture could be used up to 6 % in the broiler ration and had a positive effect on performance, blood serum lipoprotein, and carcass quality of broiler chickens.
