To study the bioactive substances of the walnut kernel of six cultivars which were newly selected from Kurdistan-Iraq and one type import from America, analyzed for their phytochemical contents and antioxidant activities. HPLC (High-performance liquid chromatography) was used for phenolic compound estimation, GC (Gas chromatography) for fatty acid analysis, and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging. In terms of fatty acids, palmitic acid, stearic acid, oleic acid, linoleic acid, and linolenic acid of all seven types we analyzed, all of them had a significant result. As for antioxidants, the same as before, the antioxidants were significant for all the chosen samples. In terms of phenolic compounds, quinic acid, gallic acid, 1,2,3,6 trigalloyl glucose, vanillic acid, syringic acid, and rutin, all types were significant as well. Finally, our results show that most of them were of high significance. Some regions in the Kurdistan region of Iraq showed high results for important secondary products, while the American counterpart is lower but still better than some of the Kurdistan region walnuts

The purpose of this investigation was to learn more about the chemical make-up of various grains and to analyze the chemical compositions, fatty acids, and antioxidant content of biscuits made with varying amounts of sesame and flax flour (0, 10, 20, and 25% replacement ratios). The chemical composition of the biscuits created by substituting sesame flour and flax indicated that the moisture content in all samples was between 5.90 and 6.33%, although the findings showed a disparity in the percentage of moisture for the various biscuit kinds. The proportion of ash increased dramatically with the replacement rates, from 1.33 to 1.70%. The BS25% treatment had the greatest protein concentration, at 14.43%. As the rate of replacement increased, a corresponding rise in protein content was seen. There was also a correlation between the replacement rates for the treatments investigated and the proportion of fats, with the highest percentage of fats being 10.33%. The BS20% treatment had the greatest fiber percentage (12.20%). The highest carbohydrate percentages (55.10-68.33%) suggested a decreasing carbohydrate ratio when replacement rates were increased. The outcomes also demonstrated that both essential and non-essential fatty acids were present in all types of grains studied. Finally, the highest proportion of antioxidants, which reached 58%, was recorded with the biscuits without any substitutes.

The study included a group of breastfeeding mothers from Salah al-Din Governorate and the surrounding villages, and the nursing mothers were divided into two groups and the number of breastfeeding mothers in each group was 6 mothers, three mothers in the city and three mothers in the village, and they were given nutritional supplements for vitamins and fatty acids, both according to his group. Results for breastfeeding mothers' milk before and after giving them nutritional supplements, there are differences in the levels of vitamins and fatty acids. It was noticed that the level of vitamins in the milk after nursing mothers took the nutritional supplement differed, so it was retinol (242-268) μg / L for mothers in the city and (213-260). g / L for mothers in the village and β--carotene (320-367) μg / L for mothers in town and (315-361) μg / L for mothers in the village and α-tocopherol (182-279) g / L for mothers in town and (120-225) μg / L for mothers in the village and calciferol (309-382) μg / L for mothers in the city and (258-269) μg / L for mothers in the village. As for the omega group for breastfeeding mothers, the levels of fatty acids in their milk were after Breastfeeding mothers take a nutritional supplement only and Mega (3,6,9) all fatty acids in the milk of breastfeeding mothers increased, so it was for lauric acid (18.02-20.01) mg / L for mothers in the city and (18.02-20.11) mg / L for mothers in the village and for palmitic acid (18.07-24.25) mg / L for mothers in the city and (24.25-26.15) mg / L for mothers in the village and for oleic acid (14.09-29.93) mg / L for mothers in the city and (29.43-29.13) mg / L for mothers in the village and for linoleic acid (22.13-28.16) mg / L for mothers in the city and (22.11-22.14) mg / L for mothers in the village, and for linoleic acid (22.26-26.59) mg / L for mothers in the city and (26.15-26.54) mg / L for mothers in the village and for Arachidonic acid (12.94-18.15) mg / L for mothers in the city and (12.94-18.15) mg / L for mothers in the village, and this explains that breast milk is directly affected by the nutritional intake and nutritional supplements taken by breastfeeding mothers during the breastfeeding period

This study was conducted at the experimental farm, Department of Animal Production , College of Agriculture , University of Tikrit for the period from 7/10/2018 to 15/12/2018. Sixteen Awassi lambs with an average body weight of 27kg and aged about 6—7-months were used in this investigation. The lambs were randomly assigned into four groups. Each group has 4 lambs the lambs were placed in individual cages (1 x 1.5 m².) and the aim of this study to investigation the effect of supplementing linseed oil on chemical composition and some fatty acids of Awassi chilled and frozen sheep meat,the results showed high significant differences in frozen period in moisture content of meat compared with chilled period it was ( 70.90 and 66.82)% respectively , and the chilled period conducted high significant differences than the frozen period in fat content ( 9.39 and 8.15)% respectively. About the effect of linseed oil on fatty acids, frozen period conducted high significant differences in Oleic it was 33.59 % while the frozen period conducted a high significant differences in Linoleic and Arachidonic acids it was ( 4.88 and 1.19)% respectively. The interaction between chilled period and treatments, the first and second treatment conducted high significant differences on Oleic acid also first treatment was high in Linoleic Acid percentage. While for the interaction between frozen period and treatments, the fourth treatment was high in Oleic and Linolenic Acid percentage, the first treatment was high in Linoleic Acid percentage it was (5.22)%.
