Konsumsi Nutrien dan Kualitas Maggot Black Soldier Fly yang diberi Pakan Protein Moderat dengan Level Kadar Air Berbeda

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh level kadar air pada pakan berprotein moderat terhadap konsumsi nutrien dan kualitas maggot Black Soldier Fly (BSF). Pakan diformulasikan dengan kandungan protein kasar sebesar 17,33% dan diberikan dalam empat kadar air berbeda, yaitu 53,87%, 65,23%, 67,96 %, dan 74,35%. Parameter yang diamati meliputi konsumsi nutrien, kandungan nutrien maggot, serta biomassa nutrient maggot yang terdiri dari bahan kering, protein, lemak, serat kasar, bahan ekstrak tanpa nitrogen, dan karbohidrat. Hasil penelitian menunjukkan bahwa perlakuan dengan kadar air 67,96% (P3) menghasilkan konsumsi nutrien tertinggi, khususnya konsumsi protein dan karbohidrat. Namun, peningkatan konsumsi tidak selalu diikuti oleh peningkatan kandungan protein tubuh maggot, karena sebagian protein dimanfaatkan sebagai sumber energi. Kandungan lemak tertinggi juga ditemukan pada P3, sedangkan kandungan protein tertinggi terdapat pada P1. Dapat disimpulkan bahwa kadar air pakan optimal untuk mendukung konsumsi tanpa menurunkan kualitas maggot berada pada kisaran 67,96%.

This study aimed to evaluate the effect of moisture level in moderate protein feed on nutrient consumption and quality of Black Soldier Fly (BSF) maggot. The feed was formulated with a crude protein content of 17.33% and given in four different moisture contents, namely 53.87%, 65.23%, 67.96%, and 74.35%. Parameters observed included nutrient consumption, maggot nutrient content, and maggot nutrient biomass consisting of dry matter, protein, fat, crude fiber, extract material without nitrogen, and carbohydrates. The results showed that the treatment with 67.96% water content (P3) resulted in the highest nutrient consumption, especially protein and carbohydrate consumption. However, an increase in consumption is not always followed by an increase in the protein content of the maggot body, because some of the protein is utilized as an energy source. The highest fat content was also found in P3, while the highest protein content was found in P1. It can be concluded that the optimal feed moisture content to support consumption without reducing maggot quality is in the range of 67.96%.
