The College of Agriculture discussed a master’s thesis on the effect of adding thyronine in starter broiler feed, low-protein final growth on productive performance, carcass traits and some chemo-vital blood traits of broilers, for the student Saddam Najm Abdullah, under the supervision of Prof. Dr. Muhammad Ibrahim Ahmed Al-Nuaimi.

The study aimed to find out the effect of adding different percentages of nutritional needs of the specific amino acid tertiary thyronine in low-protein broiler diets on productive performance, carcass traits, some physiological traits and blood vitality chemistry, as 400 one-day-old chicks of Rose 308 strain were used in the experiment. The study concluded that adding thyronine to broiler feed led to a significant increase in all studied traits. The researcher recommended adding thyronine to broiler feed to reduce feed costs by reducing feed costs. The percentage of protein in the diet.
