| Abstract |
The present work was performed to study the effect of oil, ascorbic acid and their interaction on the performance of broiler chicks during hot summmer season (28.2 – 34.3 °C) 4x4 factorial arrangement was carried out including four levels of supplemented oil (0, 1.5 , 3 and 4%) and four levels of supplemented ascorbic acid 0.00, 200, 300 and 400 mg/kg diet ). Total number of 1488 Hubbard chicks were randomly distributed into sixteen treatment groups (three replicates each). Chicks in all treatments were equal in number and had nearly similar initial body weight.
Results showed that added dietary oil did not significantly (P<0.05) affect body weight at three weeks of age, body weight gain, feed intake and feed conversion during the starting period. On the other hand, body weight at 7 weeks of age, body weight gain and feed conversion for both the finishing and the whole experimental periods improved significantly (P<0.05 or P<0.01) for chicks fed 1.5 or 3% oil as compared with those fed 0.00 % oil. The results indicated that body weight, body weight gain, feed intake and feed conversion at 1-3 weeks of age were not significantly affected (P<0.05) by the addition of ascorbic acid in the diet. However, live body weight, body weight gain, and feed conversion were improved significantly (P<0.05 or P<0.01) at 7 weeks of age for chicks fed diets supplemented with ascorbic acid, However, the supplementation of ascorbic acid at 400 mg/kg diet seemed to be the optimum level according it is best signifacant performance.
The interaction effects between oil and ascorbic acid levels were significant (P<0.05) on body weight at 7 weeks of age and feed conversion during 1-7 weeks of age. It is worthly to note that chicks fed diets supplemented with 3% oil and 400 mg/kg ascorbic acid had the best body weight and feed conversion values. Carcass traits at 7 weeks of age were not significantly (P<0.05) affected by the addition of oil or ascorbic acid and their interaction.
In conclusion, the results of this study indicated that, through the hot summer of Egypt, the best broiler performance could be obtained by supplementing oil up to 3 % of the diets.
Also, using 400 mg ascorbic acid/kg diet was enough to get the best performance and economical efficiency. Morever, supplemented 1.5% plant oil with 400 mg ascorbic acid/kg diet gave the best body weight, feed conversion and economical effocoency values.
