Comparative Evaluation of Growth Performance among Broilers Supplemented with Synthetic Lysine Amino Acid from 0-28 Days

Abstract

Different levels of synthetic lysine amino acid were supplemented to 240 starter broiler chicks randomly distributed to 12 groups of each 20-day chicks and allocated to four treatment diets in a Completely Randomized Design (CRD). T1 (Control) basal diet (0% synthetic lysine); T2 (0.15% synthetic lysine); T3 (0.3% synthetic lysine) and T4 (0.45% synthetic lysine). There was no significant difference (P>0.05) observed between treatments in dry matter, metabolizable energy, crude protein intake, body weight and death rate of the chicks. In conclusion, there were no significant changes for all parameters and further amino acid analysis of the feedstuffs is required and extra addition above 0.45% synthetic lysine of T4 need to be added in this experiment which numerically improved the chick’s performance. Further experiments were recommended to evaluate the levels of lysine amino acid in the feedstuffs and its inclusion level in to the diet of modern broiler strains.

Effect of using Compound Feeds with Different Protein Levels on Meat-type Quails

“…Most poultry nutrition research looks at protein, because the level of protein is the most important factor in the final cost of the compound feed Hertamawati et al, (2019) mention that protein and energy account for 85% of the final cost of compound feed). From the 20 amino acids that make up the protein structure, methionine and lysine levels are critically important in the composition of compound feed recipes for poultry growth (Melaku et al, 2019). In growing quails, the level of protein, mainly methionine and lysine, varies considerably in relation to the growth rate of chicks and the level of egg production in adult quails.…”
