    Performance of broiler chicken fed on diet supplemented with oregano essential oil
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022) Borah, Biswajit; Gohain, Anurup Kumar
    An experiment was conducted to study the performance of broiler chickens fed on a diet supplemented with Oregano Essential Oil. For the study, One Hundred eighty (n=180) Day old Broiler chicks of Ven Cobb 430Y strain were randomly divided into four groups (T0, T1, T2 and T3) having 45 chicks per group on the basis of their body weight, the groups were again subdivided into 3 replicates of 15 birds each. The control group was fed with basal diet or the standard pre-starter, starter and finisher diet which were formulated to meet the nutrient requirements as per ICAR, 2013 with the locally available ingredients. And the other three groups were fed with the same basal diet like the CONTROL group but with an additional supplementation of Oregano Essential Oil in the following concentrations: T1 (OEO@200mg/kg basal diet), T2 (OEO@400mg/kg basal diet) and T3 (OEO@600mg/kg basal diet). The experimental results showed significantly (p<0.05) higher change in the body weight, total gain in the body weight, total feed intake and overall feed conversion efficiency in the groups T2 and T1 than the groups T3 and T0. The Broiler Performance Efficiency Index (BPEI) was also higher in the group T2 followed by T1, T3 and T0 respectively. Digestibility of Dry Matter (DM) and retention of nutrients like Nitrogen were found to be significantly (p<0.05) better in the treatment group then the control group. The Dressing percentage (%PSW) was also significantly improved in the treatment groups; T2 was having the highest dressing % followed by T1, T3 and T0. The weight of the Cut Parts (%PSW) was better in the treatment group; however, there was no significant difference. The giblet weight (%PSW) was also not significantly different among the groups. There was no significant (p>0.05) in terms of Total protein, HDL-C, and LDL-C. The blood lipid profile was also not significantly (p>0.05) different among the different treatment groups. And also there was no significant (p>0.05) difference was observed in terms of caecal microbial load. The study revealed that supplementation of Oregano Essential Oil at a concentration of 200mg/kg basal diet improved the net profit of the broiler production. On the basis of all these experimental findings supplementation of OEO @400mg/kg basal diet was found to be better on the growth performance of the broiler chicken.
