Abstract

Globally, the utilization of alternative protein sources in livestock feed has been extensively deliberated and established to be the best novel approach. Extensive research indicated that insects provide good opportunities as a sustainable, high quality, and low-cost component of animal feed. The use of insects in animal diet sounds to be the prospective opportunity leading to sustainability of animal feeds and meet the intensifying worldwide plea for livestock products. The value of these protein sources has, however, increased due to limited production, competition between humans and animals. The use of insects for feeding farmed animals represents a promising alternative because of the nutritional properties of insects and the possible environmental benefits, given the sustainability of this type of farming. Yet little has been documented about the nutrient composition of various insect meals, the impact of insect meal in the animal feed industry, safety, and attitude and willingness of farmers to accept insect-based animal feed and food. Therefore, this chapter seeks to document the potential utilization of insect meal as livestock feed.

Highlights

  • The Food and Agriculture Organization (FAO) emphasized the importance of alternatives to conventional animal feed due to limited amounts [1]

  • They are recommended as high quality, effective, ecological substitute sources of protein

  • This chapter focuses on the Animal Feed Science and Nutrition - Production, Health and Environment documentation of the proximate nutrient composition, impact on the animal feed industry, consumer acceptance, and safety of insect meal as animal feed

Summary

Introduction

The Food and Agriculture Organization (FAO) emphasized the importance of alternatives to conventional animal feed due to limited amounts [1]. The core protein sources in monogastric animal diets are fishmeal, processed animal protein, milk by-product, soybean meal (SBM), rapeseed meal, and canola meal. The value of these protein sources has, increased due to limited production, competition between humans and animals [2]. Makkar et al [3] stated that insects are good novel protein sources at a low-cost, with regard to their high nutritional value and low breeding space requirements. They are recommended as high quality, effective, ecological substitute sources of protein. This chapter focuses on the Animal Feed Science and Nutrition - Production, Health and Environment documentation of the proximate nutrient composition, impact on the animal feed industry, consumer acceptance, and safety of insect meal as animal feed
