Effect of dietary supplementation of pomegranate peel powder and butylated hydroxy toluene on some productive, physiological and immunological parameters of japanese quail

الملخص EN

This experiment aimed to study the effect of pomegranate peel powder (PPP) and butylated hydroxy toluene (BHT) on some productive, physiological and immunological parameters of Japanese quails.

One hundred and eighty Japanese quails aged 11 weeks old were randomly divided into four treated groups, each group contain 3 replicates 15 bird each.

The first group was fed control diet without any supplementation.

While, the second and third groups were fed on diet containing 10 and 15 g PPP/kg respectively, and the fourth group were fed on diet containing 125 g/ton BHT.

The results indicated that: 1- Pomegranate peel treatments powder significantly increased body weight gain, while, feed intake and feed conversion were significantly lower in all treated groups compared with control group.

2-Egg production traits (egg number, egg weight and egg mass) were significantly increased in PPP and BHT supplemented groups compared to control.

3-Egg shell weight was significantly higher in treated groups.

While, yolk diameter was significantly longer in control than treated groups.

While, yolk color and albumin were higher at (22 wks.

of age).

4-Plasma total lipid TP, Cholesterol, low density lipoprotein LDL and high density lipoprotein HDL, creatinine, uric acid, AST and ALT significantly decreased by PPP addition .While, plasma TP was significantly increased in PPP and BHT treated groups.

5-Deftherdbody weight after slaughter was significantly increased in groups fed on 10 PPP g/kg diet.

While, heart percentage of weight was significantly lowered in quails supplemented with 15 g PPP /kg diet.

6- Supplementation of PPP and BHT didn’t affect the total micro bacterial count in instant.

7-Total phenolicswere significantly increased.

While, the TBARS values was significantly decreased in birds fed 15 g PPP/kg compared with that received BHT supplemented diet and the control group.

In conclusion, PPP addition by 15g PPP/kg diet can improve productive and physiological parameters and also can extend meat shelf-life.
