Abstract
Background and Aim:Green food is the natural diet for livestock and poultry. Therefore, production of green food in sufficient quantities to meet the current demand has emerged as an urgent problem today. The use of natural laylands results in green food shortage, which, in turn, necessitates the application of various methods of artificial production of green herbage. One of these methods is hydroponic cultivation of green grass as animal feed. Hence, this study was conducted to investigate the productive and reproductive qualities of geese of the parent herd.Materials and Methods:Complex scientific analysis was conducted to explore the effect of hydroponic green herbage used at various dosages (20%, 25%, 30%, and 35% of total diet weight) on the realization of the reproductive qualities of parent flock geese. The methodological framework of this research is the efforts of various foreign and domestic scientists on the topic under study. This research was conducted using generally accepted methods (i.e., experiment, comparison, analysis, and generalization), along with special methods (zootechnical, physiological, biological, hematological, morphological, statistical, and economic).Results:The optimal dosage of hydroponic green herbage for geese diet was established, which constituted 25-30% of the total diet weight and increased the poultry population survival rate by 2.0%, egg production rate by 3.8%, and the hatching egg yield by 4.9%. The carotenoid content in egg yolk ranged from 1.62 to 3.50 μg. The content of Vitamins A and B2 was higher by 3.19 and 2.32 μg, respectively, compared to that in the control. The production profitability level increased by 9.6%.Conclusion:By introducing 25-30% of hydroponic greens from the weight of the diet, it is possible to increase the safety of livestock by 2%, the yield of hatching eggs by 4.9%, egg production by 1.46-1.11 μg.

Summary
One of the major problems in poultry farms is to increase productivity through more efficient use of nutrients while reducing production costs. Hydroponics is one of such methods used to improve the efficiency of feed use. The use of natural laylands results in green food shortage, which, in turn, necessitates the application of various methods of artificial production of green herbage. One of these methods is hydroponic cultivation of green grass as animal feed. This study was conducted to investigate the productive and reproductive qualities of geese of the parent herd
