The Effect of Iodine in Various Forms on the Content of Selected Essential Amino Acids and Their Accumulation into the Broilers Chest Muscles

Abstract

The aim of this study was comparison of a biological effectiveness of iodized oil premix and potassium iodide premix applied in feed mixtures on the protein value and selected essential amino acids content of broiler chickens meat. According to the obtained results of experiment of broiler chickens and chemical analyses of feed and breast muscles it was found that by using iodized oil the content of the selected essential amino acids was decreased with statistically significant (P<0.01, P<0.001) compared with using of potassium iodide premix, while as the protein content was not affected by the different forms of iodine. The biological value of protein was calculated and expressed as protein efficiency ratio (PER) and it was 3.048 to 3.626 during different fattening period.
