Abstract
This experiment was performed to investigate the effects of different levels of Alhaji maurorum L. on performance, carcass traits and blood biochemical parameters in the growth period of Japanese quail. In this study, 300 quail chicks were used in a completely randomized design in 5 experimental groups with 6 replications and 10 quail chicks in each replication from 14 to 35 days old. Experimental treatments included: treatment 1 (control), treatment 2 (containing 1% Alhaji maurorum), treatment 3 (containing 2% Alhaji maurorum), treatment 4 (containing 3% Alhaji maurorum) and treatment 5 (containing 4% Alhaji maurorum). The results of this experiment showed that the groups receiving levels of 2 and 3% Alhaji maurorum had more weight gain in the whole breeding period than the control group without any significant difference in feed consumption compared to the control treatment (P < 0.05). Feed conversion ratio in the first week of rearing period in the experimental groups was affected by 2 and 3% Alhaji maurorum levels (P< 0.05). The effect of using different levels of Alhaji maurorum on meat quality parameters was also considerable and the meat of birds fed with different levels of Alhaji maurorum had a higher water holding capacity than the meat of that of birds in control group (P< 0.05). Also, the percentage of drip loss, cooking loss and freezing loss in the experimental groups was significantly lower than the control treatment (P< 0.05). Malondialdehyde concentration in groups receiving different levels of Alhaji maurorum was significantly affected by experimental treatments (P< 0.05). Different levels of Alhaji maurorum had no significant effect on the liver enzymes aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase, while 2% Alhaji maurorum level caused a significant difference on lactate dehydrogenase concentration with the control group. Different levels of Alhaji maurorum in the diet had significant effects on total antioxidant status and antioxidant enzymes, and levels of 2 to 4% of Alhaji maurorum had higher total antioxidant capacity as well as serum superoxide dismutase and glutathione peroxidase enzymes than the control treatment (P< 0.05). Treatments receiving different levels of Alhaji maurorum in the challenge with sheep red blood cells had higher antibody titers than the control group (P< 0.05). According to the results of this study, it was concluded that 2 and 3% levels of Alhaji maurorum have the best effect on the quality and performance parameters of growing Japanese quail and therefore the use of these levels of Alhaji maurorum in their diet is recommended.
