Pengaruh Penggunaan Rumput Laut Dan Pare Dalam Ransum Terhadap Jumlah Leukosit Dan Persentase Bobot Bursa Fabrisius Ayam Broiler

This research study was aimed to determine the influence of using seaweed (Gracilaria verrucosa) and bitter melon (Momordica charantia) on the total leukocytes and bursa fabricius of broiler chicken. The experiment used 100 DOC (Day Old Chicken) broilers. The rations for broiler consisted of seaweed, bitter melon, bran, soybean meal, poultry meat meal, and topmix. The experimental was design used was a completely randomized design with 4 treatments and 5 replications, each replications consisted of 5 broilers. Rations classified as: T0 = control rations without seaweed and bitteer melon, T1 = rations using 2% bitter melon, T2 = rations using 7% seaweed, T3 = rations using 2% bitter melon and 7% seaweed. The parameters measured were total leukocytes and relative weight of bursa fabricius at 3 weeks age. The results showed that the treatments were significantly affected (P<0,05) total leukocytes, but not (P>0,05) on the relative weight of bursa fabricius. The total leukocytes on T0, T1, T2, T3 is 12,35 (×10 3 /μl), 9,98 (×10 3 /μl), 9,02 (×10 3 /μl), dan 10,81 (×10 3 /μl), and relative weight of bursa fabricius is 0,28%, 0,25%, 0,18%, dan 0,21%. The conclusion is that the using seaweed and bitter melon in rations can increased endurance were reflacted the normal conditions on the total leukocytes and relatif weight of bursa fabricius.
