The research was conducted at the Taj Al-Nahrain cattle station in Al-Diwaniyah governorate in Iraq on a sample of 85
Holstein cows imported from Germany, which were selected during the third season of milk production, in order to
determine the genotypes of the PIT-1 gene and its relationship to a number of production traits. The PCR product (451bp)
of the PIT-1 gene was digested using the Hinf1 restriction enzyme, and the digestion results showed that the studied
genetic segment of the POU1F1 gene appeared in three genotypes (AA, AB, and BB) with percentages of 55.3, 42.6,
2.1%, respectively, and there were highly significant differences (P≤0.01) between the distribution of these percentages,
and the A allele (0.766) was superior to the B allele (0.234). The results of the analysis of variance showed that the effect
of the genotype of the POU1F1 gene on the characteristics of milk production (daily milk production, total milk
production, peak production) was not significant except in the characteristic of peak milk production in favor of the BB
genotype at a rate of 538.50 kg on each of the genotypes AA and AB while the results did not show a significant effect
between the genotypes (AA, AB, BB) in both the daily milk production rate and the total milk production. It was found
that the effect of the POU1F1 gene on body dimension traits (body length, frontal body height, posterior body height) was
significant (P≤0.05) in body length in favor of the BB genotype (164 cm) on each of the genotypes AA and AB, at
157,780. and 156,347 cm, respectively, while there were no significant differences between the genotypes in the anterior
height and posterior height of the body

current study was conducted to show the effect of culturing common carp Cyprinus carpio with different densities in
floating cages in the Euphrates River in Nasiriyah city, Dhi Qar governorate, on some growth indicators, for a period of
(10/17) 2020 until 10/6/2021). Four different treatments were used in the density of culture (200, 300, 400, 500)
respectively, and the average weight ranged between (42-55) g. Floating cages made of PVC were used, the same diet
was used to feed fish for the four treatments. The results of the current study were evaluated according to growth criteria
(total weight gain, daily weight gain, relative growth rate, specific growth rate, food conversion factor, food conversion
efficiency, protein efficiency ratio). The results showed that the first treatment, followed by the second treatment,
outperformed the third and fourth treatments. It was concluded from the current study that the lowest densities of
common carb achieve the best rates of growth indicators.

This study was conducted to investigate the effect of in ovo injection of hatching eggs with Omega 3 Oil at 18 days old, in
the amniotic sac in the air sac, on some productive characteristics of broilers ROSS 308. The eggs were injected into the
Al-Bazz hatchery in the holy governorate of Karbala, as for raising hatched chicks from injected eggs, it was conducted in
the poultry hall in the research station of the Department of Animal Production, College of Agriculture and Marshes, ThiQar University, from 12/1/2020 to 25/1/2021. A total of 450 eggs from ROSS 308 broiler breeder were used in this
experiment, distributed into five treatments as follows: T1; The first treatment (negative control): hatching eggs left
without injection. T2; The second treatment (positive control): hatching eggs injected with sunflower oil. And another
treatment T3, T4 and T5 were injected hatching eggs with 0.1, 0.2 and ml of omega-3 oil respectively. 300 chicks from
the hatched chicks were distributed in cages with dimensions of 1 x 1.5 m for each cage, at a rate of 60 chicks for each
treatment, with three replicates of the treatment (20 chicks for each replicate). The results of the study indicated that there
was a significant (P < 0.05) improvement in the studied productive traits (body weight, weight gain, feed intake, feed
conversion factor).

The study was conducted at Taj Al-Nahrain station in Al-Diwaniyah Governorate, which is 200 km from the center of Dhi
Qar Governorate. For the period from 10/15/2021 to 4/15/2021, 85 Holstein cows imported from Germany were used in this
experiment, and they were selected from among 700 cows in the station, all of which are in the third production cycle. As for
the laboratory part of the study, it was conducted in the laboratories of the Department of Life Sciences at the College of
Science / Dhi Qar University for the purpose of separating the genetic material (DNA), conducting polymerase chain reaction
and electrophoresis, and identifying genetic mutations in the studied genetic segment on the prolactin gene, The animals in
the station were fed according to the season and year in terms of the availability of feed and the percentage of costs involved
in raising cows, as well as depending on the general state of cow productivity. But in general, it is provided with green
fodder, which includes yoghurt, barley, corn stalks, and a percentage of both dry feed (hay and hay) and concentrated feed
(barley, bran and cake) according to what is available from them, as well as limestone and table salt. The data on milk
production were collected from the station records, where the milk production was recorded weekly for the morning circuit
and the evening circuit by the station, and the milk components were analyzed in the Abu Ghraib Dairy Company / Research
and Development Division by a Milk Analyzer, and 3 ml of blood was collected from a vein The udder of each cow was
given by medical syringes with a capacity of 5 ml, suitable for the size of the animal’s vein, and placed in collection tubes
containing an anticoagulant substance (K2 EDTA) and transferred in a cooler box for freezing at a temperature of -18°C until
the time of extraction. From the results obtained from this study, it can be concluded that the mutation C83T changed the
code of the amino acid histidine to the amino acid Tyrosine, which had a significant effect on the characteristics of daily and
total milk production, while the mutation G168C changed the amino acid arginine to the amino acid Proline, which was
significantly reflected on the traits of persistence. In milk production, the length of the milk season and the proportion of
milk protein, most of the average traits for cows in the third season of production appeared higher than the general averages
compared to other studies, and most of the simple correlation coefficients between the study traits were high and significant.

This research is concerned with outlining the strategies supporting the mechanisms of the dissemination of agricultural
technologies in Romania. The problem in Romania in this respect is dueto a lack of a mechanism of dissemination of the
agricultural technologies caused by a lack of the extension of knowledge from the units responsible for itsuch as lack of
consultancy services and directions. This has affected the understanding of the importance of agricultural technologies by
farmers. In an attempt to solve this problem, Romania has adopted a number of strategies for the dissemination of
agricultural technologies among farmers and specialists. Among these strategies is encouraging the Management Entity of the
Cluster \"Sviluppo Insieme si Vince\" that created IND AGRO WEST, the first innovative cluster for research and
development in Romania, aimed at achievement of modern agriculture equipment, appropriate to Romanian soil (Sviluppo,
2014). Another strategy is finantially supportinginnovations and projects conducted for addressing the issue of agricultural
technology dissemination through funding and financial support. For example, Climate smart agriculture is one of the key
topics for the almost 3,000 innovation projects that are expected to receive funding from the Rural Development budget.
Around EUR64 million will be dedicated to precision farming and digital technologies in the agriculture sector under the
Horizon 2020 Work Programme for 2016-2017 while EUR30 million will be invested in the implementation of an Internet of
Things Large Scale Pilot on “Smart farming and food security” (Michalopoulos, 2016). Another strategy is creating institutes
that are concerned with the dissemination of agricultural technologies in Romania. The mission of the National Research and
Development Institute for Machines and Installations for Agriculture and Food Industry is to carry out scientific research
(fundamental and applicative), innovations in the field of processes, technologies and technical equipment leading to the
mechanization and automation of agricultural works and the food industry, in the context of harmonizing the whole activity
with ANCS policies. It is also important for Romania to search for collaboration with other countries such as Netherlands
that runs many projects to transfer to Romanian farmers\' a better understanding of technology.

This study was conducted in the animal field of the College of Agriculture and the Marshes / University of Dhi Qar for
the period from 11/6/2020 to 16/2/2021. In this experiment, (12) Arabi dairy sheep were used with their lambs ranging in
age from one and a half to two years, single and close in birth. The times of their birth, and their average initial weights
were (43.90, 48.50, 44.60) kg for the first, second and third treatments, and after giving the ewes a preparatory stage for
two weeks, the ewes and their lambs were randomly distributed between three treatments (nutrition) equally, and each
treatment was four replicates, and the ration was given to the ewes on the basis of 3% The ewes of the first treatment
were fed a control ration consisting of (25% barley, 25% wheat bran, 20% crushed corn, 20% flour, 7% soybean meal
and 3% salt) and the second treatment (basic ration + 3 gm yeast /head /day) and the third treatment (basic diet + 5 gm
yeast /head/day) and straw was provided freely to all the mothers of the different treatments.The weights, weight
increases and the amount of feed consumed were recorded. Presence Excellence moral (0.05≥P) inThe lambs weighed,
and there was a moral superiority 0.05≥P) in the second week of the experiment only for the treatment (3 gm yeast / head
/ day) Its value was (16.47) kg compared toworth transactions, while There are no significant differences in the rate of
total and daily weight gain of lambs in all treatments Experience On Although there was an arithmetic increase in favor
of the treatment (5 gm yeast /head /day)

The current study was conducted in the animal field of the College of Agriculture and Marshlands / University of Thi-Qar
for the period from 6/11/2020 to 16/2/2021 to know the effect of adding different percentages of bentonite and vitamin C
to the diets of male Arabized lambs, as the study included the use of (16) males Arabized lambs, and the experiment
lasted for 100 days. The lambs were taken after weaning at the age of 5 months, with an average weight of (28 kg ± 1.24).
The animals were randomly divided into four groups, with four lambs per group. The first group-included animals fed the
basic diet. T2 animals were fed with bentonite added to the basic diet at a rate of 20 g/kg dry weight, T3 were fed with
vitamin C in the form of capsules at a rate of 50 mg/kg live weight in addition to the basic diet, while T4 animals treated
with 10 g bentonite/kg dry weight added to the diet + 25 mg vitamin C / kg live weight provided to the animal in the
form of capsules. Hay was offered freely to all the different transaction lambs. The results were statistically analyzed
using the complete random design, a significant increase (P≤0.05) was observed in the average body weight, The average
daily and total weight gain of the third group animals (treated with vitamin C) compared to the control group and the
other treated groups, as the average body weight increased from the start of the eighth week until the twelfth week, a nonsignificant increase was also observed in the amount of feed consumed and the food conversion efficiency of the T3
group compared to the control group

The current study dealt with the culture of three different densities of common carp, Cyprinus carpio.L. In floating
cages in the Garraf River / north of Shatrah city, from 12/2/2020 to 7/7/2021 to obtain the best density of culture per
cubic meter. To study the optimal growth, three densities (25-50-75 thickness/m3) were used: 1000 fish for the first
treatment, 2000 fish for the second treatment, and 3000 fish for the third treatment, with an average weight ranging
between 103 ± 2 and with two replicates for each treatment. One local diet was used for the three treatments, the first
treatment recorded a survival rate of 96%, the second 93.3%, and the third 91.98%. The results of the experiment were
evaluated according to the following criteria: total weight gain, daily weight gain. Feed conversion rate, feed conversion
efficiency. The current study showed the superiority of fish from the first treatment with less significant density than the
rest of the treatments, followed by the second treatment and outperformed the third treatment. The chemical analysis
showed an increase in the protein contents of the fish body after the experiment for all the treatments in a row, and there
were no significant differences for the fish components among the three treatments.

The aim of the current study is to treat cases of repeat breeder in crossbreed cows and to improve
pregnancy rate in affected cows. The study divided the number of animals into four groups, group
(10 = T1), where the first group gave human chorionic gonadotropin on the day of oestrus and
repeated the same dose 1500 IU Five days postinsemination and the group (T2 = 10) where the
hCG hormone was given at a dose of 1500 IU on the day of the estrus and Flunxin meglumine
treatment with a dose (2ml / 50 kg b.w) each ml contain to (50mg of FM) from the fifth day post
insemination for three days and the third group, which numbered 5 cows in the group (C1 = 5),
were considered a control group without treatment, while the fourth group(C2=5) is considered
fertile cows, the purpose of their presence in the study is to evaluate the effectiveness of the fertility
of the semen straws used in the study. The study showed that the pregnancy rate in cows in
the groups, respectively, is 40%, 60%, 0%, 60%. The statistical analysis showed that there
were significant differences at (P˂0.01) between the treated and fertile groups and the
untreated group, which means an improvement in the pregnancy rate in treated cows that
were suffering from repeat breeding. Early pregnancy was diagnosed rectally using
ultrasound

This study was conducted in the animal farm of the College of Agriculture and Marshes / University of Dhi Qar for the
period from 6/11/2020 to 16/2/2021 to study the effect of using different levels of kefir milk on the performance of local
goats kids. The study included (16) local males kids of Iraqi Local goats. And the experiment lasted 100 days.
Introductory 16 day of adapt .The goats were taken after weaning at the age of 3-4 months with an average weight of
(19.59 ± 2.81) kg. They were purchased from the local markets and were examined by the veterinarian to ensure their
safety and free from diseases. The goats were randomly divided into four groups with four kids for each group. The feed
was provided as 3% of the live body weight. The quantities of feed provided were adjusted every two weeks based on the
new mean weight of each group. The experimental animals were randomly divided into four treatments

A field experiment was carried out in the College of the Agriculture / University of Basra to
study the effect of four types of subsoiler leg shapes, three tillage depths, and three tractor
speeds in draft force, slip percentage, fuel consumption, and mean weight diameter (MWD).
A randomized complete block design was used in a factorial experiment for data analysis.
The results showed that the serrated edge of 45-degree angle surpassed on straight,
serrated edge, 70-degree angle serrated edge, and curved in oat yield by a percentage of
2.4,18 and,21% respectively. However, serrated edge of 45-degree angle recorded less
draft force, lower slip percentage, fuel consumption, and main weight mean diameter while
the highest values of the previous characteristics were for the straight edge. The results
showed that increasing tillage depth led to increasing slip percentage, fuel consumption, and
draft force, also the previous characteristic increased with increasing forward speed. It was
concluded that the best combination was obtained when using a 45-degree angle serrated
edge and the speed of 2.34 km / h which gave the lowest fuel consumption of 8.11
liters/ha. Also, the 45-degree angle serrated edge at 10 cm tillage depth gave the lower
fuel consumption of 8.78 liters/ha.
