Chicken Feather Silage Meal As A Fish Meal Protein Source Replacement In Feed Formula Of Pomfret (Colossoma macropomum)

Abstract

The research was conducted to know the effect and to determine the best utilization of the chicken feather silage meal as a substitute for fish meal protein source in the feed formula of Colossoma macropomum. This study used experimental method based on Completely Randomized Design (CRD) with 5 treatments and 3 replications. Five diets (33% isoprotein and 3.85 kcal/g diet isoenergic) were formulated with substitution of the chicken feather silage meal to fishmeal protein. These substituted 0, 25, 50, 75 and 100 % (A, B, C, D and E respectively) of the fishmeal protein. Parameters observed and analysed were: survival rate, specific growth rate, feed conversion ratio, protein efficiency ratio, protein retention and protein digestibility. The results showed that the treatment had no effect on survival rate, specific growth rate, feed conversion ratio, protein efficiency ratio, and protein retention but the effect on protein digestibility. Based on these results, it can be concluded that fishmeal protein can be substituted with the chicken feather silage meal up to 100% in the feed formula of Colossoma macropomum.

“…The chicken carcass will be boiled before giving it to their fish. It's the similar with the use of chicken feathers as fish feed (Ekawati et al 2016).…”

Chemically Treated Chicken Feather Meal for Fish Feed

“…The research was conducted by substituting fishmeal by chicken feather meal as much as 0%, 25%, 50%, 75% and 100% with maintenance media in the form of aquariums [1,26,27]. From the results of research that has been conducted, it is known that processed or partially hydrolyzed chicken feather meal at various levels in feed formulations can replace the role of fishmeal [28].…”

“…Broiler production per year reaches 2 billion birds with an average harvest weight of 1.5 kg/head. From this, it can be estimated that the total broiler feather waste reaches 120.00 tons/year or the equivalent of chicken feather meal of around 36.000 tons/year [1].According to BPS (2023) every year the number of chicken slaughter increases, in 2018 it was 3.137.707.479 heads and in 2019 it increased to 3.169.805.127 heads [2]. Until now, a small portion of chicken feathers are only used as upholstery filler, plant fertilizer, crafts or decorations, shuttlecocks and feather duster [3].…”

“…In principle, processing of chicken feathers aims to weaken or break the bonds in keratin through hydrolysis [7]. Of the several processing methods, chemical processing with acids or bases (NaOH, HCI) is a more efficient processing because the processing method is easy and also cheap [1]. Therefore, it is necessary to conduct a literature study (review) in order to provide a clear picture of chicken feathers and their practical utilization through chemical processing.…”

A Review on Chicken Feather Flour Potential for Fish Feed

“…Pada prinsipnya, pengolahan bulu ayam bertujuan untuk melemahkan atau memutuskan ikatan dalam keratin melalui proses hidrolisis. Perlakuan kimia dengan asam atau basa (NaOH, HCI) yang dapat meningkatkan nilai kecernaan sampai dengan 50-60% (Ekawati et al 2016). Menurut Puastuti (2007), metode pengolahan bulu ayam terbagi menjadi empat macam yaitu fisik menggunakan temperatur tinggi dan tekanan, enzimatik, mikrobiologis dengan fermentasi dan kimiawi dengan asam, basa atau karbonasi.…”
