| dc.description.abstract | The objective of the research was to study the effect of reducing feedstuff and dringking water on the level of thyroxin and the alteration of the hematocrit, haemoglobin values and erythrocyte count. The research was used 180 medium types chicken, strain Dekalb Warren, 84 weeks old. The research applied 2x2x2 factors and used complete randomized design in 5 times replications with 4 chickens for each repetition. The first factor was water supplying and without water supply was every second day. The second factor was the duration of no feeding for 10 and 5 days. The third factor was the amount of feed given during recovery period that was 50% and 25% of the normal consumption, respectively. The total of the treatment of force molting program applied were 9 treatments. Thus, the research was used 160 chickens (8x5x4=160 chickens) and 20 .chickens for control (1x5x4=20 chickens). The data obtained were analysed using analysis of variance (Anova), orthogonal comparison test. The result showed that stress could increase the level of thyroxin significantly p < 0.05 at day 5, and at day 10 (p<O.Ol) compared with the control group. The result also showed that stress could increase hematocrit and haemoglobin value significantly (p < 0.01) at day 2, 5,10 after treatment, respectively. | en |
