Based on the experimental data, one can conclude that feed rations may comprise peas
var. ‘Bruno’ and faba beans var. ‘Lielplatone’ grown in Latvia, thereby replacing the use of
imported soybean cake. After summarising the results of trials, one can conclude that the diets
comprising only one kind of legumes (peas or beans) were the most economically efficient, while
the highest production efficiency was achieved if incorporating 22–24% ‘Lielplatone’ faba beans
into the diet for dairy cows. In Europe and Latvia, foods of animal origin comprise, on average,
45% of the total agricultural output value; an essential role in the production of the foods is played
by the supply of protein-rich feedstuffs to the livestock industry. An analysis of the factors
influencing productivity in dairy farming shows that a diet is the most important factor that
promote or hinder the functioning of the inherited genetic potential. In order to meet the dietary
energy, protein and mineral requirements of cows, the cows have to be fed a diet according to
their physiological condition. In recent years in many countries, research investigations into
protein sources have been conducted, as a high protein content of feedstuff is the most expensive
component of a feed ration. For this reason, their use in livestock diets might be economically
inefficient and therefore the key focus has to be placed on opportunities to increase the content
of protein in domestically produced feeds.
