Abstract:
This study was carried out at the Poultry Research Unit, Lattakia Research Center in 2022. One hundred and twenty sauces of the commercial hybrid Ross at the age of one day were distributed in four groups and three repeaters for each group in order to study the effect of using a group of medicinal plants in the form of feed powder, namely garlic, thyme, marjoram and anise, and the effect of using an aqueous extract on some productive indicators of broilers. The birds underwent similar care conditions of heat, humidity, veterinary care, feeding and drinking water. Medicinal plants powder was added with the feed mixture when feeding and aqueous extract with drinking water, the experiment lasted for 38 days.The control group T was fed on the unified concentrated feed for all groups without any addition, while the first experimental group T1 received commercial extract with drinking water and the second and third experimental groups T2,T3 received a mixture of local medicinal plants powder with feed mixture (0.3% thyme, 0.4% anise, 0.15% garlic and 0.25% marjoram) in T2. (0.15% thyme, 0.2% anise, 0.075% garlic and 0.12% marjoram) in T3. The results showed the positive effect of the introduction of medicinal plant powders with the feed mixture and to a lesser extent its aqueous extracts on the productivity indicators of broilers. The second and third experimental groups T2 and T3 outperformed the control group (P<0.05) with an average weight at the end of the experiment, which was higher in the T3 group (2574 g). The T3 group also outperformed the average feed consumption (P<0.05) over the rest of the groups, which was 2.8% lower compared to the control. All experimental groups outperformed the control group (P<0.05) with a conversion factor, which was the best in T3, reaching 1.45, and the experimental groups T2 and T3 outperformed the control group (P<0.05) with an average carcass weight and netting ratio. The inclusion of medicinal plant powders had a positive impact on all productive parameters.
Keywords: broilers, weight gain, conversion factor, carcass weight, dressing percentage.
