Effect of the concentrate “Rumifos” on the mass and the degree of reproduction of rain worms

Abstract

The article deals with study of effect of a new, innovative, plant product concentrate of local origin “Rumifos” on the mass and the degree of reproduction of the rain worms and, establishes its efficient and optimal doses. The maximal (Max.), nominal (Nom.) and minimal (Min.) doses in milliliters of the plant substance of the concentrate “Rumifos” to be added to the substrate of the trial group are calculated. Weighting and counting the cocons were conducted in three stages, on 21st, 31st and 41st days after beginning the experiment. Average change of masses by grams and percent in the control and trial groups and average number of cocoons in pieces and percent, were studied in each stage, while. An average change of the mass of trial groups in comparison with the control one during the total period of the experiment and an average degree of increase of the reproduction of cocons, as well as the efficient and optimal doses of the concentrate “Rumifos” were established also. It is found that when balancing the substrates of the rain worms trial in comparison with the control group, no significant changes take place. As to the degree of reproduction of the cocons, on the first stage, this indicator in comparison with the degree of reproduction of the control group cocons (100%), it varies within 1411.0–1633.67% ranges, while the optimal and efficient dose of the plant concentrate “Rumifos” is 0.31ml., calculated for 600g substrate. Thus, balancing the rain worms substrate by “Rumifos”, has a positive effect on the mass growth of the worms and increases considerably the degree of reproduction of the cocons, that, as we suppose, is preconditioned by diversity of various biologically active chemical class compounds existing in the composition of the concentrate “Rumifos”. The obtained results will have importance for that direction of vermiculivation, where the protein mass of the rain worms is used for balancing the combined feed for farm animals and poultry, as a vitamin-protein, high quality concentrative additive.
