An experiment has been carried out in broiler house belonging to Karbala Agriculture Directorate from April 2-22 in which 80 chicks (Cobb and Ross) at the age of one day were used distributed randomly on eight treatments (Two times for each treatment including 10 chicks).And according to complete random design C.R.D with an experiment (2×4) to study the effect of Sesbania(Sesbaniaexaltata) seeds partial replacement with soybean meal in a grown diet with percentage of ( 0% , 15%, 30%, 45%) for two hybrids to reveal weight gain , entire microbial content , colon cell bacteria in digestive duct, some blood features (number of red blood cells and white blood cells, P.C.V and H/L ratio are include) for hybrids and percentage of replacement as well as treatments.
The results have shown that there were no significant differences regarding the weight gain at the age of 30, 40 days. In addition to the total number of bacteria and colon bacteria in the percentage of replacement, hybrids and treatments .As for blood features at the age of the 24 days. It has been noticed that there were significant differences (P˂ 0.05)in numbers of red blood cells particularly in the percentage of 30%, 45% comparison to 0% ,15% ,but such effect hasn't appeared in hybrids and treatments regarding white blood cells .The percentage (30%, 45%)have surpassed in significant difference (P˂ 0.01) compared with (0%,15%).AS for the hybrid (Ross), on the other hand , there was a significant difference (P˂ 0.05) compared with (Cobb).
For the treatments, there weren't any significant differences. The results ,additionally, have shown that there were no significant differences particularly of H/L ration in the percentage of replacement , hybrids and treatments as well .The results have pointed out that P.C.V in the percentage of replacement 30%,45% has more significant (P˂ 0.01) than 0%,15% but there wasn't such a significant difference in hybrids and treatments.
The blood feature have continued for being surpassed at the age of 35 days expect for white blood cells in which there was no significant difference in the hybrids and also for P.C.V as noticed that there was no significant differences in the percentage of replacement, hybrids and treatment. |
