Abstract

It was evaluated the performance of eggs and meats production, fat of blood lipid profile, blood haematological, immunity, and organs lymphoid of safflower oil and inositol on Sentul chicken(female and male ). This research used 162 birds (81 female 81male ) was the males one-month-old was raised throughout (8 weeks) including one week for adaptation, the bird has been slaughtered at the age of 12 weeks, the female was 16 weeks old which were raised throughout (8 weeks) including one week for adaptation. Nine experimental diets were formulated to meet the nutrients requirements of Sentul chicken in addition to the basal control diet (T0) without safflower oil and inositol, eight experimental diets were formulated to contain safflower oil and inositol, on basis of safflower oil and inositol, At different levels, T1= 0.5% safflower oil, T2 = 0.5% inositol, T3 = 1% safflower oil, T4 = 1% inositol, T5 = 0.5 % safflower oil + 0.5% inositol, T6 =0.5% safflower oil + 1% inositol, T7 = 1% safflower oil + 0.5% Inositol, T8 = 1% safflower oil + 1% inositol. It was arranged based on a Completely Randomized Design of nine experimental with three replications, each replication with three birds. The measured variables of meats and eggs production, blood lipid profile, blood haematological, immunity, organs lymphoid and digestive profile. The results showed the treatments had no significant effect (P>0.05) on performance and the digestive profile, except carcass and non-carcass, had significant differences (P<0.05) of male which was carcass higher at (T7) 705.04±18.19 to decrease (T8) 624.31±28.28 and non-carcass which was recorded at (T3) 284.43±11.16 to (T4) 225.48±12.41, fat of blood lipid profile, hematological, titer antibody of ND was the non-significant effect (P>0.05) of males and females, except total cholesterol of significant male differences (P<0.05) which was the highest treatment at T8 (148.15 )and T 7 (148.15). In contrast, egg production had significant differences (P<0.05) of females which recorded higher at (T1) 65.44±2.84 %, while significantly affected (P<0.05) to fat eggs yolk, were fat eggs yolk showing higher at (T7) 17.56 and titer antibody AI had significant differences (P<0.05) of males and females, were recorded higher of titer antibody AI in (T5) 15.33 and (T4) 200 of males and females. Weights of the thymus, bursa of Fabricius, and relative weight were not significantly different (P>0.05), while there was a highly significant difference (P<0.01) at the spleen which was between T1 6.13± .05 to T7 2.68±.07 of males. In contrast, the spleen and thymus did not have a significant difference (P>0.05) in females the relative weight of the bursa of Fabricius was significantly high (P<0.05) in females was at higher at (T4) 18.77g. It can be concluded supplementation of safflower oil and inositol up to 1% had increased some Sentul chicken's performance. Also, it can maintain the stability of relatively the same values for blood profile, hematological parameters, and digestive organs and does not influence the physiological mechanism. Therefore, it had improved the immune response of titer antibody increased at AI, indicating that the healthy Sentul chicken.
