Abstract
Nutritional and biochemical experiments were conducted on Apis mellifera L. honey bee colonies in the apiary of the College of Agriculture / University of Tikrit for the period from 1/12/2018 to 1/2/2019 to study the effect of some natural food supplements and pollen substitutes on the activity of honey bee colonies and the body content of workers’ from Basic chemical compounds The results of the treatment of feeding with pollen supplements showed the presence of significant differences between the treatments, and the treatment (pollen + honey + protein) was superior, and its value reached (73.00 , 359.67 ,36.00 and42.17) ang2, respectively, and the treatment (pollen + honey) gave the lowest value. In the open and closed brood area, it reached (11.33 and 5.33) ng2, respectively. The results also showed significant differences in the effect of pollen supplement feeding on the chemical composition of the insect’s body. The comparison treatment exceeded the moisture content, as well as carbohydrates and ash, reaching (69.10 ,41.26 and 5.24) % respectively, and it gave the treatment of (pollen + honey) and treatment (pollen grains). + Honey + protein (the highest percentage of protein in the body of the insect was) 54.16 and 54.19 % respectively. The treatment of (pollen + honey + palm pollen + protein) exceeded 10.04% and the proportion of chitin increased in the treatment (pollen + honey + protein) as it stood at 77.14%.
