The effect of feeding different levels of dandelion leaf powder (Taraxacum officinale) in the diet on the productive and physiological performance of broiler chickens, strain Ross-308.

Abstract

This study aimed to know the effect of feeding different levels of dandelion leaf powder on the productive and some physiological traits of broiler chickens, in which 180 one-day age chicks of the unsexed Ross 308 strain were used. The chicks were distributed randomly into 4 treatments that included each treatment (3 replicates at an average of 15 chicks for each replicate). The transactions were divided into The first (control) treatment was without addition, the second, third and fourth treatments included the addition of dandelion leaf powder at a concentration (1.0,1.5,2.0) g/kg feed respectively. The results showed that there was a significant increase (P<0.05) for T2 and T4 birds in the mean live body weight and total weight gain, with a significant decrease (P <0.05) in the total feed consumption rate and obtaining the best feed conversion factor for T4 birds compared to the rest of the treatments. In addition, there was a significant decrease (P <0.05) in the blood glucose and triglyceride concentrations of the two treatments T2 and T4 birds, with a significant decrease (P <0.05) in the cholesterol concentration and a significant increase (P<0.05) in the Glutathione peroxidase concentration in the blood serum of T4 treatment birds compared to With the other treatments, a significant decrease (P <0.05) of Malnualdehyde concentration (MDA) was obtained for all additive treatments compared to control. We conclude from this that adding dandelion leaf powder at a concentration of (1.0, 2.0) g / kg feed to the broiler chickens diet has a positive effect on improving the productivity and some physiological traits of broiler chickens.
