This experiment was conducted in the sheep farm of Department of Animal Production, College of Agriculture, University of Anbar, during the period of 17/10/2021 to 9/1/2022. Sixteen local male lambs were chosen between 5-6 months of age and 35.31 ± 3.72 kg of average body weight. The aim of the experiment was to determine the effect of melatonin implants and nutritional restriction on some blood biochemical parameters of local male lambs. The experimental period lasted for 69 days, the experiment involved two phases, feed restriction phase (42 days), and realimentation phase (27 days). Lambs were randomly distributed into four equal groups with four lambs of each. During the restriction phase, first group (T1) was used as a control and feed ad libitum. The second group (T2) was feed ad libitum and treated with two implants of melatonin (36mg) subcutaneously at the base of the ear. The third group (T3) was feed restriction 75% of ad libitum intake. The fourth group (T4) was feed restriction 75% of ad libitum intake and treated with two implants of melatonin subcutaneously at the base of the ear. Blood samples were collected from all treated groups at day 0, 42 and 69 for the measurement the level of glucose, total protein, triglyceride, aspartate aminotransferase (AST), alanine transaminase (ALT) and malondialdehyde (MDA) in the plasma. The results restricted feeding, with or without melatonin, did not affect significantly on blood biochemical parameters, while it was observed that the restricted feeding with or without melatonin significantly reduced the level of malondialdehyde. It was concluded from this experiment that feeding local male lambs at a level of 75% of ad libitum  with or without melatonin implants for 42 days followed by realimentation for 27 days improved oxidative status in male lambs.

This study was conducted in the poultry farm belong to Department of Animal Production at College of Agriculture, University of Anbar, from 20/7/2021 to 15/10/2021, to show the role of vitamin D3 and multi particle size of oyster shells to providing the needed calcium for laying hens in order to manufacture the eggshell throughout the hours of the day and its impact on shell quality and bone health.one hundred-eight Lohman Brown laying hens, 43 weeks of age, were distributed randomly to nine treatments, four replicates for each treatment and three hens for each replicate. The experimental treatments were as follows: T1/ control diet without any additives, T2/ calcium source 50% limestone + 50% oyster shell size less than 1 mm + vitamin D3 4000 IU kg-1, T3/ calcium source 50% limestone +50% oyster shell size 1-2 mm + vitamin D3 4000 IU kg-1, T4/ calcium source 50% limestone + 50% oyster shell size 2-3 mm + vitamin D3 4000 IU kg-1, T5/ calcium source 50% Limestone + 50% oyster shell size 3–5 mm + Vitamin D3 4000 IU kg-1, T6/ Calcium source 50% limestone + 50% oyster shell size less than 1 mm + Vitamin D3 8000 IU kg-1, T7 / Calcium source 50% limestone + 50% oyster shell 1-2 mm +Vitamin D3 8000 IU kg-1, T8 Calcium source 50% limestone + 50% oyster shell 2-3 mm + Vitamin D3 8000 IU kg-1, T9/ Calcium source 50% limestone +50% oyster shell size 3-5mm + Vitamin D3 8000 IU kg-1. The results showed a significant increase (P≤0.05) in levels of calcium in blood plasma for fifth, sixth, seventh, eighth and ninth treatments. The results indicated a Significant increase (P≤0.05) in level of vitamin D3 in blood plasma for the sixth, seventh, eighth and ninth treatments. The results showed a significant increase (P≤0.05) in tibia bone breaking strength and Calcium content in tibia bone for the sixth, seventh, eighth and ninth treatments. The results of eggshell breaking force trait indicated significant increase (P≤0.05) for fourth, fifth, sixth, seventh, eighth and ninth treatments.

Using mycorrhizal inoculum in sustainable agriculture attracted immense attention in recent years for improving plant growth, and water uptake. A plastic pot experiment was carried out at the College of Agricultural Engineering Sciences, University of Sulaimani, during June to Juley 2020 to study the effect of different mycorrhizal inoculum (Glomus mosseae, Glomus geosporum and a commercial inoculum INOQ Agri) on growth responses and water use efficiency (WUE) of two maize varieties (GLORIA and SY Miami). The root colonization percentage for GLORIA and SY Miami were (5, 83.33, 88.33, 88.33) % (3.33, 86.67, 78.33, 85) % for control, G. mosseae, G. geosporum, and INOQ Agri, respectively. Inoculated plants showed significantly better growth and water use efficiency compared to non-mycorrhizal plants. The best plant heights were in INGQ Agri plants (91.33, 90.67) cm in both GLORIA and SY Miami respectively. Highest shoot biomass (49.83, 44.50) g pot-1 and root biomass (16.17, 15.67) g pot-1 were found in INGQ Agri inoculant in both GLORIA and SY Miami respectively. The heights concentration of N,P and K  were in INOQ Agri (1.53%, 0.61% and 0.14%) for GLORIA and (1.48%, 0.56% and 0.14%) for SY Miami  respectively, Mycorrhizal inoculation also improved (WUE)  in maize plants the average increasing percentage were (34.92%, 19.3%) for  GLORIA and SY Miami cultivars respectively.
