The EU Member States have a high deficit of domestic protein feeds, and approximately 70% of protein products are imported; thus, feed price fluctuations make the European livestock industry economically vulnerable. It is possible to use domestic agricultural by-products as a feed for agricultural animals in order to reduce the deficit of protein feeds and the cost with regard to purchasing such feeds. To tackle the problem regarding reducing the production cost of livestock products, a feeding experiment on broiler chickens was conducted using protein concentrate Baltiprot – an ethanol production by-product with high protein content – produced in Latvia. The hypothesis is as follows: using the ethanol industry by-product – protein concentrate – in diets of poultry could increase broiler chicken productivity and reduce feed cost. In this aspect, the aim was to identify the most economically efficient amount of protein feed in the diet of broiler chickens. The research results showed that a greater slaughter weight of poultry (+6.48%), a lower production cost per kg of poultry meat (-7.11%), a higher production efficiency (386.2) and a lower feed conversion ratio (1.77) could be achieved by using the protein additive in the diet of broiler chickens.
