Efisiensi Konsumsi Pakan dan Laju Respirasi Ulat Sutera Bombyx Mori L. (Lepidoptera: Bombicidae) yang Diberi Daun Murbei (Morus Sp.) yang Mengandung Vitamin B1 (Tiamin)

Abstract

The Effect of Mulberry (Morus sp.) Leave that Contain Vitamin B1 (Thiamine) on the Efficiency of Feed Consumption and Respiration Rate of Silkworm Bombyx mori L. (Lepidoptera: Bombicidae)” has been carried out in the Laboratory of Genetics, Faculty of Mathematics and Natural Sciences, University of Sumatra Utara, Medan. This study used Complete Random Design (CRD) with 5 treatments and 3 replications each replication consisted of 10 silkworm. The treatmants that vitamin B1 concentration of mg/100ml 0,0; 0,1; 0,2; 0,3; 0,4. The rate of consumption relative increased to the concentration of 0,4mg/100ml, and respiration rate concentration 0,4mg/100ml (p<0.05). But, not increase the relative growth rate, efficiency of convertion of digested food, efficiency of convertion of ingested food and approximate digestibility.
