Evaluating the suitability of maggot meal as a partial substitute of soya bean on the productive traits, digestibility indices and organoleptic properties of broiler meat

Abstract

This study was conducted to replace soya bean meal with maggot meal at difference percentages. A total of 120 one-day-old broiler chicks were divided into four groups. Four diets were formulated with maggot meal to replace soya bean meal at the rate of 0%, 10%, 20% and 30% designated as A, B, C and D respectively. Feed and water were offered ad libitum during the study which lasted for 28 days. Feed intake decreased significantly in treated groups while body weight, Feed conversion ratio and dressing percentage increased significantly in group D. Apparent metabolizable energy increased significantly in the group fed 30% maggot meal; however, no significant difference was found in dry matter, crude protein, crude fibre, ether extract, ash and nitrogen free extract between the control and treated groups. The result of sensory evaluation revealed that tenderness and juiciness increased significantly in group C and B respectively. The colour and flavour were most accepted in group B and C. The results indicate that replacement of soya bean meal at the rate of 30% in broiler feed produced most favourable results.

Evaluating the nutritive profile of three insect meals and their effects to replace soya bean in broiler diet

“…Findings of the current study are in the line with the results of Khan et al. () and Okah and Onwujiarir () who concluded that feed intake was decreased in the group fed maggot meal in the ration. Poorghasemi et al.…”

“…Similarly, Okah and Onwujiarir () and Khan et al. () also reported significantly higher weight gain in birds offered with insect meal (maggot meal).…”

“…Higher nutritive profile of maggot, silk and mealworm and their suitability to be used in broiler feed has been previously reported (Khan et al, 2016;Makkar et al, 2014); however, the comparison between different insect meals in broiler diet is lacking in the literature. The composition of maggot meal varies with the method of production, processing, harvesting and the substrate used for its production, weather conditions and the fly type (Aniebo et al, 2011;Atteh & Adedoyin, 1993).…”

“…Soya bean is a rich source of protein; however, due to high cost and dependency on its import, there is an increased demand for the alternative and easily available protein sources (Khan et al., ; Laudadio, Dambrosio, et al, ; Laudadio, Passantino, et al, ). Recently, there is an increased interest in the utilization of maggot meal, silkworm meal and mealworm as potential protein source in broiler ration (Bovera et al., , ; Khan et al., ; Van Hhuis et al., ). The use of different types of insect meals could potentially reduce expensive imported soya bean meal without compromising bird performance.…”

“…Estimated feed cost of the poultry industry is up to 60%–75%, and protein cost accounts for over 15% of the total feed cost (Awoniyi, Adebayo, & Aletor, ; Khan, Durrani, Chand, & Anwar, ; Khan et al., ). Nowadays, there is a growing interest in the use of the protein‐rich insects as a protein source in poultry ration (Van Hhuis et al., ).…”
