Some Biochemical Indices of Broiler Chickens Fed Graded Levels of Lysine Supplement, Maiduguri, Nigeria

This research study was conducted on some biochemical indices of broilers chicken fed graded levels of lysine supplement in Maiduguri was carried out to determine their biochemical indices and ascertained the level of inclusion of lysine in poultry feed. Standard operating procedures were followed. 120 day-old broiler chickens were obtained commercially, grouped in to 4 experimental treatments and was randomized complete block designed (T); T1, T2, T3 and T4 with 15 birds per treatment and each with replicates. Brooded for a week with starter feed, experimental diets of which lysine supplement was added to T2, T3 and T4 at 0.02, 0.03 and 0.04 %, but not to T1 as control. Feeds and water were provided ad-libitum, for 4 weeks. Blood samples were obtained through Veni-puncture for serum biochemical indices analyses and estimations by AAS techniques as described by AOAC [1]. Results obtained revealed the values of mean concentration level in mmol / l of; alanine amino transferase ranged from 46.10 to 53.10, albumin (25.02 to 36.00), aspartate amino transferase (36.11 to 68.00), blood urea (2.10 to 3.20), creatinine (1.60 to 2.20), globulin (14.00 to 18.00), glucose (5.71 to 6.01) and total protein ranged from 39.00 to 52.01 respectively. Lysine supplement was found to be effective at 0.02 to 0.03 % of. Both the values fall within the normal range values and the results obtained are in conformity with the works of most authors and researchers.
