ISSUE FOCUS 30 FEED & ADDITIVE MAGAZINE October 2022 “It is estimated that around 34 percent of the protein in human diets originate from animal products. This amount is increasing due to the growth in the middle-class population globally, with more disposable income available to purchase animal derived proteins as a food source. A rise in demand for animal protein is coupled with larger volumes of feed production, therefore, more protein sources are needed to fulfil the needs of these animals...” Protein is probably one of the most expensive raw materials needed in the production of animal feed and very often imported, which raises the cost of the finished feed tremendously. Proteins used in animal feeds are ranked according to the digestibility as well as their amino acid profile. Superior proteins will be easily digestible and contain all the essential amino acids needed by the animal to support all biological processes. When the protein sources used in animal feeds are not easily digestible, an excess of nitrogen, over and above the normal amount, will be excreted by the animal which causes a negative impact on the environment as it may potentially pollute the soil and water in the surrounding areas. It is estimated that around 34 percent of the protein in human diets originate from animal products. This amount is increasing due to the growth in the middle-class population globally, with more disposable income available to purchase animal derived proteins as a food source. A rise in demand for animal protein is coupled with larger volumes of feed production, therefore, more protein sources are needed to fulfil the needs of these animals. Consumers are becoming more aware of the sources of the food that makes up their diets, which means there is growing concern about feed safety as well as sustainability and the impact of animal rearing on the environment1. Production animals require protein in their diets for growth and overall health and wellbeing as proteins are needed for the regeneration and growth of muscles and organs. Typical diets of domestic animals can vary in the amount of protein they contain, depending on the age, type of animal as well as the physiological state of the animal. This article will give a brief overview of the classification and potential notification and/or registration processes required for different protein sources used in animal feeds. CONVENTIONAL PLANT-BASED PROTEINS • Soybean Considered one of the most popular sources of protein used in animal feeds, especially for monogastric animals. It is produced as a by-product during the oil extraction process of whole soybeans. NON-CONVENTIONAL ALTERNATIVE PROTEINS IN FEED REGULATIONS IN THE EU Is it the answer to less soymeal in animal feed? Dawn Botha Technical Marketing Manager Pen & Tec Consulting
