Abstract
This study aimed to examine ferula dietary supplements on broilers productive performance and physiological parameters under stocking density and heat stress. A total of 480 one-day-old chicks were split up into nine treatments, each with four replicates. The experimental treatments included three control negative and positive treatments of both stocking densities: the control (base diet). Three levels of ferula powder (4, 8, and 12 g/kg of diet) were used for both stocking densities. The temperature was raised to 4°C over the typical range that birds require to survive. The temperature was set at 22°C and then increased to 26°C for 24 hours each day, and they were given constant light for 20 days of rearing without a break. In every phase, the treatment's LBW and BWG did not differ significantly from the negative control. Feed intake was significantly higher in the negative control group than in the positive control groups (8 g ferula/kg feed ) and(12 g ferula/kg feed ). FCR did not change compared to the control group. At 35 days of rearing, the low- density chicks' body weight, weight gain, feed intake, and feed conversion ratio are significantly higher due to stocking density than the high-density chicks. Significantly raises the positive control group's mortality rate when compared to the negative control group. There is a notable increase in the production index in the negative control group as compared to the positive control group and T2. There was a significant rise in antioxidant (GPX) in negative controls. Eventually, (MDA), there are notable improvements in positive control compared to treatments.
