Abstract
Hematological parameters were evaluated by conducting trial investigations on Day old chicks Hy-Line strain using GroPro as a feed additive under open house management systems at field laboratory of Sumber Sekar, Malang Easy Java. Fresh water and feed were offered ad libitum. The total number of chicks 480 which were divided into four treatment groups with six replications each, using a Completely Randomized Design. The treatments included P0 (control, no GroPro), P1 (0.2% GroPro), P2 (0.5% GroPro), and P3 (1% GroPro) with duration of 7 weeks. In total 8 blood samples were drawn in random be through brachial cut at the close of trials. The data were analysed by using ANOVA analysis, and if the result is significant then continued with the Duncan^s Multiple Range Test. The results show the treatments were significantly (P<0.01) affected all variables including Hemoglobin (Hb), Mean Corpuscular Hemoglobin (MCH), Packed cell volume (PCV), Red Blood Cell (RBC), White Blood Cell (WBC), except Mean Corpuscular Hemoglobin Concentration (MCHC) which shows no significant result (P>0.05). Therefore, it is concluded that GroPro at level 1% inclusion positively influences hematological study of laying hens at starter phase well define its health status and help-out in diagnosis and treatment of birds.
