EFFECT OF IODINE ON THE CONTENT OF AMINO ACIDS AND BIOLOGICAL VALUE OF FODDER CROPS IN CLEAN AND MIXED SOWINGS
Long-term studies on the effect of iodine on the content of protein, amino acids, amino-acid score and essential amino acids in the seeds of fodder crops have been conducted. The results of studies show that iodine activity causes enhancement of nitrogen metabolism. This causes an increase of protein content, the total amount of amino acids and essential amino acids for human beings and animals both in single crops and in mixed sowings. It is observed that the experimental plants develop more intensively and the length of inter-phase periods is reduced at 3-5 days under the influence of iodine. It is established that the content of protein is higher in legume plants as compared with cereals. The maximum content of all the amino acids has been observed in trials with peas (50%) + barley (50%) + iodine and vetch (100%) +iodine. It is ascertained that lysine and leucine belong to limiting amino acids. The biological value of feeds is being improved under the influence of iodine as result of increasing the amino-acid score.
