abstract
In the present study, the bone meal blended cow dung was developed as a feeding material for Lampito mauritii earth worm and there impacts were tested based on reproduction cycle. For the studies, initially the bone meal was mixed with cow dung (1:1 ratio) and used for the earth worm feeding. The feeding material impacts were tested up to 150 days based on earth warm biomass, clitellum and cocoon production. The bone meal-cow dung feeding materials showed the maximum biomass value was 1567 ± 0.5 mg and the control showed the biomass value was around 1000 ± 0.7 mg. The Coon production results indicated that the maximum 135 ± 4.1 cocoons were produced in bone meal- cow dung feeding material and the control samples showed the value was around 120 ± 3.4. From these results, the bone meals – cow dung feeding material was highly suitable for Lampito mauritii species growth and reproductions. This paper for the first time addresses the bone meal mixed cow dung as a feeding material for Lampito mauritii earth worms and it opens up a new possibility for the development of vermi compost production from bone mill wastes.
