This study was conducted at the University of Baghdad / College of Agricultural
Engineering Sciences to show the effect of adding lemongrass leaf powder
(Cymbopogon citratus) and vitamin C to broiler ...diets at different levels on the
productive traits of broilers. This experiment was conducted in the poultry field
(Abu Ghraib) / Department of Animal Production / Agricultural Engineering
Sciences/ for a period from 10/15/2021 to 11/26/2021 for a period of (42 days).
The study used 240 unsexed commercial hybrids (Ross 308) of one-day-age
chicks. They were randomly assigned to 6 treatments and 4 replicates for each
treatment (10 chicks/duplicate). The experimental treatments were as follows:
Control treatment T1 (feed without supplement), treatment T2 (add lemongrass 2
g/kg feed), T3 (add lemongrass 4g/kg feed), T4 (add lemongrass 6g/kg feed),
treatment T5 (add lemongrass 8g/kg feed), Treatment T6 (add vitamin C 0.5 g/kg
feed). Suppose we noted no differences between the addition treatments and the
control treatment during the experiment period in the productive traits. In that case,
we note that there are no significant differences between all the additional
treatments compared to the control treatment despite their arithmetic differences.

This study was conducted in a private field for duck breeding in Al-Muthanna
Governorate from 12/14/2021 to 02/14/2022. The study included oxytetracycline's
effect on some Chinese ducks' productive ...traits. 60 unsexed, one-day Chinese duck
chicks were used, prepared from one of the hatcheries in Al-Qadisiyah Governorate. They were randomly distributed to 4 treatments, including 3 replicates for
each (5 chicks for each replicate). The treatments were as follows: T1: control
treatment. T2, T3 and T4 were added to 0.125, 0.250 and 0.375 mg oxytetracycline/ kg diet. The results indicated that using oxytetracycline significantly improved some productive traits of Chinese ducks, body weight, weight gain, feed
intake and feed conversion factor. Added the antibiotic to feed at a concentration of
0.375 mg per kg of feed gave the best results significantly compared to the rest of
the treatments.

The database was obtained from 4560 records multiple records were collected from 2000 to 2022 For a total of 2560 records for Sakha station and 2000 records for El-Qardah station of the Ministry ...Agriculture and land reclamation in Egypt, meteorological data were obtained from the central laboratory of Agricultural climate. The data was divided into two periods, the period from 2000 to 2010 (P1) and the period from 2011 to 2022 (P2). Thermal Humidity Index (THI) and season effect on productive traits (LTMY, TMY, LP and DP) were between significant (P<0.05) and high significant (P<0.01) For both groups, except the effect of THI on the DMY in (P2) and season effect on DMY in (P1), which were non-significant. Climate change in the period from (2011 to 2022) witnessed a rise in temperature (AT) and was followed by an increase in relative humidity (RH) and atmospheric pressure (AP), as well as an increase in the value of THI especially the summer season, which is hotter than the rest of the seasons this had a negative effect on the productive traits. Estimates of permanent environmental variance for the second period for most traits were lower than additive genetic variance it may indicate that sensitivity to heat stress is not specific to the cow but is hereditary. Heritability estimates are low to moderate for most milk production traits show the possibility of improving genetically by selecting the most valuable cows for Heritability or genetic selection of cows and improving herd management.

The experiment was carried out in the poultry field of the Department
of Animal Production/College of Agriculture/the University of Diyala from
4/9/2021 to 10/14/2021 to study the effect of adding ...Cynara scolymus L. )artichoke( extract to the diet of broilers. It was used as an antioxidant to show its effect on birds' productive, physiological and immune performance. In this experiment, 225 unsexed Ross 308 hybrid broiler chicks were used (one day age), with
an initial weight of 44.36 g/chick. These chicks were randomly distributed from
the first day of receiving them to five experimental treatments with three replicates for each treatment (15 birds/repeat). The experimental treatments were: T1
= (control treatment) provided a standard diet free of additives, T2 = Standard ration plus 75 mg/L artichoke extract, T3 = a standard diet supplemented with 150
mg/L artichoke extract, T4 = Standard ration to which 2 g/kg of artichoke extract
is added, and T5 = Standard ration to which 3 g/kg of artichoke extract is added.
The experiment results indicated a significant effect on product traits when adding different artichoke leaf extract powder levels to Ross 308 broiler water and
diet (1-42 days). Generally, treatment T3 was significantly (P<0.05) superior in
the fourth week in recording the highest average live body weight of 3170.90 g,
and treatment T4 was significantly (P<0.05) in the fourth week and recorded the
highest rate of weight gain. Also, treatment T1 in the first week recorded the
highest rate of feed consumption, treatment T2 in the first week recorded the
highest efficiency of food conversion, and treatment T3 significantly (P<0.05)
and recorded the highest rate of productive evidence.

This experiment conducted using 20 Rahmani ewes at the last third of pregnancy in two equal groups. One group served as control, while the other group received Spirulina platensis (SP) at the rate of ...0.5 gm 10 kg-1 live body weight. The objective was to find out the effect of adding Spirulina platensis algae to small ruminant rations on reproductive and productive traits and blood components of sheep. The experiments lasted for 120 days for both dams and their lambs after weaning. The findings proved that adding SP in ewes' diets had no effect on the average of live body weight change. Average milk yield was significantly (p <0.01) higher in the treatment group than the control. Lamb's birth weight and daily body gain of the treated group were significantly (p <0.01) higher than the control. Blood and serum picture profile of ewes were significantly higher when fed SP additive than the control. It could be concluded that the addition of SP to the ration of sheep positively preserved their health, productive and reproductive status as well as their lambs' growth rate. Also the additive improved the economic efficiency of treated animals by about 53.13%.
The main goal of this experiment was to evaluate the effect of broiler strain and source of drinking water on some performance traits (body weight and carcass traits). Sample of water were taken from ...two different location sources, Giza governorate (as Nile water) and Qalubia governorate (as well water or ground water). Three different broiler strains were used in this study (Arbor acres, Hubbard and Cobb). Lead concentration (as a heavy metal element) and bacteriological analysis (total bacteria and fecal coliforms) in both water and carcass were carried out. The main results obtained can be summarized as follow: Arbor acres strain recorded the heaviest body at most ages compared to the other strains, the difference was highly significant at 5 and 6 weeks of ages. Total bacteria were significantly high in ground water compared to Nile water. Conversely, Coliforms bacteria count was significantly high in Nile water compared to ground water source. Regardless strain type, high positive correlation between lead concentration in drinking water and lead concentration in liver, kidney and carcass weight was observed
Prevention of Newcastle disease has received a lot of interest across the world. The high productivity performance of the commercial chickens’ breeds has negative effects on the immune system and ...animal welfare. As a result, the current study aimed to investigate the benefits of adding Artemisia powder at levels of 0.5% and 1% to broilers’ feed as a growth and health promoter. A total of 120 commercial broiler chickens were grown on the floor in a chicken house and separated into three groups, including one control and two treatment groups. Each group contained 40 chickens subdivided into two replicates. The three groups, namely G1 (chickens without Artemisia powder, as a control group), G2, and G3 in which chickens were fed with basal diet plus 0.5% and 1% Artemisia powder, respectively, were differentiated based on their diet throughout 35 days of the experiment. The measured parameters included the immune response to Newcastle disease vaccine, blood biochemical parameters, and growth performance as well as relative weight for the spleen and bursa of Fabricius. A diet containing 1% Artemisia powder significantly improved antibody titer against Newcastle disease, body weight, and weight gain. Thus, the addition of 1% of Artemisia powder to the broiler’s diet can improve immune response against Newcastle disease and growth performance.
