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.

Abstract: 

This research was conducted in 2022, in both its productive and molecular parts, the blood samples was taken from 70 laying hens of the Bovans White global hybrid layer and were subjected to DNA analysis, three genetic loci associated with egg production trait were studied (APH-09, APH-24, ADL-209). The egg-laying curve was studied for a period of 73 days, and the performance of the hybrid chickens was evaluated in terms of productivity. Eggs were weighed on a daily basis and for each individual separately in order to calculate the average weekly egg weight. The age of sexual maturity for the individual and for the flock separately was recorded. The number of eggs produced reached 73 Eggs in 13 individuals at the age of 31 weeks. The percentage of egg productivity reached 99.48% in the month of peak production, and the weekly average egg weight reached 54.28 grams in the 31st week of the birds’ life. The age of sexual maturity of the individual was recorded ranging from the age of 121 days at its minimum to 150 At its maximum, the age of sexual maturity of the flock was recorded at 145 days. the percentage of flock productivity reached 50% on two consecutive days. The molecular results showed the variation of individuals in the studied hybrid flock in terms of the absence or presence of alleles and in the total number of alleles found in each of them. The total number of alleles obtained on the three genetic loci was (18) alleles with an average of 5.666 alleles/one loci, while the genetic diversity values reached 0.248, 0.104, and 0.184 in the studied loci APH-09, APH-24, and ADL-209, respectively With an average of (0.178), this genetic diversity is a natural result in the Bovans White hybrid flock. The 18 chickens that showed alleles of the genetic loci studied were characterized by high productivity ranging from (0.84-1).
