This study was conducted at Poultry farm/Department of Animal Production/College of Agricultural Engineering Sciences/University of Baghdad, were divided into two experiments one during summer and second during winter seasons to study the effect of season and sex on productive performance of Pekin duck reared in an intensive system under harsh Iraqi conditions. A hundred fifty, one day old ducklings were used in each experiment. On 14 day of age, birds were sexed then randomly divided into nine replicates (pens) (5 replicates for females and 4 for males). Results indicated that season has significant effects on studied traits. Body weight, weight gain and food consumption were significantly ( p < 0.01 )higher in birds reared i

This study was conducted to determine the percentage of hatchability, post-hatch growth performance, immune response of broiler  subjected  to in- ovo injection of different doses of rosemary oil. A total of 300  eggs of ross broiler strain were obtained.The experiment distributed into five treatment groups: T1, Negative Control T2, positive control (in ovo injection of 0.05 ml distilled water) T3, in ovo injection of 0.05ml of rosemary oil; T4, in ovo injection of  0.075 ml of rosemary oil; T5, in ovo injection of  0.1 ml of rosemary oil.Highest hatchability  percentage was shown in 0.1ml rosemary oil -injected hatching eggs. The final weight of birds from 0.075 and 0.1 ml of rosemary oil-injected e

This experiment was conducted from 1/7/2016 to 20/12/2018 to study the mineralogical properties of oak forest at 12 locations (Gara, Matin and Brifca) from Dohuk governorate, (Bilah, Malakan and Awagrd) from Hawler Governorate, (Bardanga, Badawan and Chwarta) from Sulaimani Governorate, and (Bakhakon, Hawar and Sartak) from Halabja governorate in Iraqi Kurdistan region. The samples collected from a depth of (0 – 60) cm for laboratory analysis. The study includes qualitative identification of clay minerals by X- ray diffraction data. Peak height was used as a rough indicator of relative abundance of minerals. In general, the expansion of 14°A to ≈ 17°A in ethylene glycol treatment was not detected because the measuring was s

Anise (Pimpinella anisum) is an annual herbaceous flowering plant, its widely used as spices, flavoring agent and fragrance. Anise seeds and its essential oils (EOs) has been used widely in the recipes of folk medicine in the Arab region, including Iraq. Therefore, the goal of this work was to extract and define the chemical compositions of aniseeds EOs, and study its antioxidant, antibacterial, and antibiofilm potentials. Aniseed EOs were extracted by hydro-distillation technique using Clevenger apparatus. Twenty-five distinct compounds have been recognized by Gas chromatographic–Mass spectral (GC-Mas) analysis, the major constituents were anisole (87

The current study was conducted to determine the ideal period for freezing of three fish species of in the Iraqi local markets which are common carp  Cyprinus carpio ,catfish Silurus triostegus and mullet Planiliza abu  through sensory evaluation and the effect of freezing time on the flavor, juiciness and general acceptability of fish .A total of20  samples, were taken for each species of fresh local fish and were frozen at 18°C for different freezing periods : 1 day (T2), 15 days (T3), 30 days (T4) and 45 days (T5) , in addition to the fresh treatment T1 that has not been subjected to freezing. Results of common carp showed that the be

The purpose of this experiment was to increase poultry meat production by increasing the number of chickens reared in the same area and managing it by using medicinal herbs Salvia officinalis L and Lavandula angustifolia L. in the broiler chicken diet. 705 one-day-old chicks were randomly distributed into to7 treatments with three replicates for an area of two m² floor system in each replicate for each treatment, during 35 days of the study. T0 negative control 75 chicks, 25 chicks for each replicate 12-13 chicks per m² fed standard diet. T1 positive control (stocking density without supplementation)105 chicks, 35 each replicate chicks 17-18 per m2 fed standard diet. The same stocking densi

This study was aimed to investigate the effect of surface sprinkler and drip irrigation systems using a model AquaCrop, irrigation intervals, bio-organic fertilizers and polymers in desert soils. Two field experiments were conducted during the spring season 2020 at Karbala governorate. The experiment included three factors: 1-Irrigation system surface drip T₁ and sprinkler T₂, 2- The Irrigation interval: every 2 days I₁, 4 days I₂ and 6 days I₃, 3- Addition of soil conditioners: control without any addition C, bio-organic fertilizers (seek) B, polymer (zeba) P, and polymer+ bio-organic fertilizers P+B.

This study was aim to investigate performance of seed drill - fertilizer (GIL-SAX multisem18) was evaluated under two different farming systems (till and no-till) and tractor speeds (5.28, 7.76 and 8.30 km.h^-1). The characteristics were measured including draft force, wheel slip, seed delivery rate, and germination rate. The experiment was organized as a randomized complete block design (RCBD). The significant difference was examined using the least significant difference tests at a P≤0.05. The results showed a minimum draft force and wheel slip under the till system and tractor speed of 5.28 km.h^-1 intera

A field experiment was carried out during two spring seasons in 2019 and 2020. This study was aimed to increase dry matter weight and crop growth rate of maize. First factor in main plots was nutrition vegetative parts with ascorbic and citric (100 mg l^-1) for both of them and humic (1 ml l^-1), in addition to the control treatment (spraying of vegetative parts with distilled water only). Second factor in sub-plots was seeds soaking with same acids above, as well as the control treatment (soaking the seeds with distilled water only). Randomize complete block design in split plot arrangement was used with three replications. The results showed a significant superiority of seeds soaking in humi

This study was aimed to determine the residual concentrations of pesticides used in greenhouse cucumber fields and their effects on the farmers that spray it. Sixteen active cucumber greenhouse fields with 96 people (75 sprayers and 21 volunteers as control) randomly had been selected. In all selected greenhouses, abamectin, thiamethoxam, pyridabin, and spirodiclofen pesticides were used, their cucumber with leaves and groundwater collected in December 2017, March, June, and September 2018 with workers blood samples, were immediately brought to the laboratory. Results showed the occurrence of residual pesticides in the plant and groundwater samples with a highest
