The study was conducted in the laboratories of the College of Agriculture, University of Tikrit, where functional biscuits were produced that treat some pathological conditions in children from malnutrition and intestinal diseases, which were prepared with different mixtures to find out which of these mixtures is better. Among the studied treatments, the standard treatment amounted to 4, while the treatments began to decrease until it recorded 3.19 in treatment D, and the results of the chemical analysis observed an increase in moisture and ash in treatment D to reach (4.33, 2.66)%, respectively, while fat and protein recorded the highest percentage in treatment B, which amounted to (9.97, 16.71)%, but carbohydrates had the highest percentage in the standard treatment, which amounted to 76.12%. Through the sensory evaluation of the samples and through the sensory evaluation, the results showed that the characteristic of color was high in treatments B and C, which amounted to 19 compared to other treatments, while the characteristic of taste and flavor increased in treatment C, which scored 29, while the characteristic of texture was high in the two treatments A, C which amounted to 19. When the treatments were stored in polyethylene bags for a period of 28 days at room temperature and the hardness was measured, the highest value was for treatment A, which ranged from (4.32-7). This indicates that the addition of materials high in the percentage of protein increases the hardness of biscuits with an increase in the storage period.

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
