This experiment was conducted at Poultry field, Agricultural Research and Experiment Station, College of Agriculture, Al-Muthanna University from 12/2/2020 to 6/1/2020. A total of 240 oneday, 40 g, Ross 308 broiler chicks, were used. The chicks were reared in four-storey batteries. Each floor contains a cage of dimensions 1.5 × 1 m. The chicks were randomly distributed to four experimental treatments of 60 chicks. For each treatment, three replicates of the treatment (20 chicks/duplicate). The treatments were as T1, T2, T3 and T4were add water extract of chia seeds to drinking water by 0, 2, 4 and 6 ml/liter of drinking water respectively.

The study was conducted at the poultry field, the Agricultural Research and Experiments Station, College of Agriculture, Al-Muthanna University, from 12/6/2019 to 2/28/2020 (12 weeks period), divided into six durations, each period of 14 days. A total of 84 layer hen (ISA Brown), 21 weeks of age, distributed randomly into four treatments, were distributed into four pens (3 x 3 m) and each was divided into three equal parts, each section contains 7 laying hens (21 laying hens per treatment). The treatments were as follows: T1 (control treatment): given the basal diet without any additives. T2: CrCI 3 was added at a concentration of 10 ppm / kg feed. T3: CrCI 3 was added at a concentration of 15 ppm / kg feed. T4: CrCI 3 was added at a concentration of 20 ppm / kg of feed. The results of the study indicated that the added levels of inorganic chromium decreased significantly (P≤0.05) in the cholesterol concentration, with a significant increase (P≤0.05) in albumin, globulin, and total protein in blood plasma in the inorganic chromium treatments compared to the control treatment.

In this study, the old chicken meat found in the market after slaughtering and cleaning was carried out by the saline application, which was as follows T: the control treatment. T2, T3 and T4 were tenerized spent hen meat with sodium chloride by 10, 20 and 30 g/L water for 12 hours respectively. Results show that the collagen was a significant increase (P≤0.05) in T2, T3, T4 compared with the control of white muscle control and the total concentration of collagen was a significant decrease (P≤0.05) in saline annulus coefficients compared to control of dark muscle. The total concentration of soluble nitrogen was a significant decrease (P≤0.05) in saline-induced salinity coefficients compared with white muscle control. It is also noted that the concentration of protein nitrogen in the white muscle has decreased significantly (P≤0.05) in the coefficients of the antigen compared to the control treatment.

The study was conducted at the sheep and goat research station, at Al-Shatrah District, Thi-Qar Agriculture Directorate, Thi-Qar Governorate, from 1/11/2021 to 30/6/2022 for one production season. A total of 100 animals were used, consisting of 50 parents and 50 lambs, males and females; the ages of the ewes ranged from 3 to 5 years old. The sheep data used in the experiment were collected from the station records. The genetic part was also completed in the Marshes Research Laboratory at the University of Thi-Qar. The study aimed at the genetic polymorphism of the leptin gene and its relationship to the body dimensions of the Awassi sheep. The nitrogenous base sequence analysis of the leptin gene indicated a size of 260 base pairs, with a change in location 119 in the studied area. The homozygous CC genotype was more significant than the number of animals; the frequency of the C and T alleles was 0.65 and 0.35, respectively. There was no significant effect between the three genetic polymorphisms resulting from the mutation at site 119 of the studied plot on the body dimensions of the newborns as well as at weaning. Keywords: Polymorphism, leptin gene, body dimensions, Awassi sheep.

The current study was conducted in experimental cages in a mud pond, First Agricultural Research and Experiment Station, Agriculture College, Al-Muthanna University, to determine the effect of different levels of Moringa oleifera seed powder on the diets of common carp. A total of 75 common carp fish with an average weight of 65.08±0.42 g were used; it was randomly distributed to 5 treatments with three replicates (5 fish for each replicate). The fish that were fed on experimental diets was divided into five equal therapies in terms of protein percentages, different in the proportions of adding Moringa seed powder; the rate of seeds added to the treatments was 0, 0.5, 1, 1.5 and 2%, respectively, the fish were fed on the experimental diets at 5% of the live weight, divided into four meals a day. The results showed a significant superiority of T2 and T3 treatments compared with other therapies on growth parameters (final weight, weight gain, daily growth rate, specific and relative), and give the best feed conversion ratio, the highest food conversion and protein efficiency ratio. Indicates that adding Moringa seed powder to diets at rates of 0.5 and 1% led to fish growth promotion and increased utilization of feed intake.
