Effect of Partial Replacement of Fishmeal with Leucaena leucocephala Leaf Meal on the Growth Performance of Tilapia zilli Fingerlings

Abstract

Aims: A study was carried out to determine the effect of replacing fishmeal with Leucaena leucoephala leaf meal in the diet of Tilapia zilli fingerlings.
 Study Design: Three hundred (300) Tilapia zilli fingerlings (9.5±0.5 g/fish, mixed sex) fed with diet containing Leucaena leucoephala leaf meal for 10 weeks at 0%, 2.5%, 5.0%, 7.5% and 10.0% level of inclusion, representing the replacement of fish meal at 0%, 25% 75% and 100% respectively.
 Place and Duration of Study: A study was carried out in the wet laboratory of Fisheries Technology department of Lagos State Polytechnic, Ikorodu between July 2017 and October 2017.
 Methodology: Tilapia sp. fingerlings were treated with five diets including a control experiment of which each treatment was replicated thrice, the total number of replicates was fifteen and the experiment was laid out in a completely randomized design.
 Results: Statistical analyses revealed that there was no significant difference (P=05) in weight gain, feed conversion ratio and protein efficiency ratio.
 Conclusion: L. leucocephala can be recommended in the diet of Tilapia zilli because of its economic in terms of cheapness and abundance especially in the tropical region and its nutritional values as a good source of plant protein.

Growth performance and cost-effectiveness of replacement of fishmeal with plant-based protein source, Leucaena leucocephala in the diet of Clarias gariepinus fingerlings

“…The crude fibre reported in this current study was higher than the 13.85% reported by Adedeji et al (2013) but lower than 19.20 reported in the work of Babalola and Fakunmoju (2020). The improved crude fibre in the tested leaf meal can aid in bowel movement, favoring nutrient absorption and reducing constipation (Lunn and Buttriss 2007;Amobi et al 2019).…”

“…de Wit, commonly known as Leucaena or white leadtree is one of the suitable plant protein alternatives to fishmeal for fish feed due to its medium-high protein content, suitable levels of amino acids and most importantly, very affordable market price tag (De Angelis et al 2021). However, few studies have demonstrated that Leucaena leaf meal can successfully replace fishmeal as a protein source in fish diets at different inclusion levels (Bairagi et al 2004;Tiamiyu et al 2015;Babalola and Fakunmoju 2020).…”

Feed Additive Vegetable Oil, Addition to Commercial Feed on the Feed Efficiency and Fat Content of Red Tilapia (Oreochromis Niloticus)

“…The efficiency of feeding is directly proportional to the addition of body weight, so the higher the value of feeding efficiency means the more efficient the fish use the feed consumed for growth [10]. The feed can be said to be good if the feeding efficiency value is more than 50% or even close to 100% [11].…”

Potential Use of Ipil-Ipil (Leucaena leucocephala Lam.) As Fish Feed Ingredient: A Mini-review

“…The effect of using Leucaena leaf meal in this study established that it could be used at recommended level of inclusion in the fish diet. the use of plant protein, But the used of Leucaena leaf meal to replace animal protein in the diet of Tilapia zilli fingerlings in order to reduce competition between man and animal which often times precede the scarcity and over prizing of it as emphasized by [19].…”
