Tsenov, P., Sericulture and Agriculture Experimental Station, Vratza (Bulgaria)
A silkworm artificial diet created by the author, contained 38 % mulberry leaf powder, 34 % defatted soybean meal and the rest 28 % - corn starch, agar agar, citric acid, ascorbic acid, microelements and vitamins, antibiotic and preservatives was used in the study. The aminoacids, microelements and vitamins were included as water soluble aminovitamin premix, produced by Ascor Chimici srl, Italy. Five experimental groups were tested, containing zero g, 5 g, 10 g, 20 g and 30 g of aminovitamin premix per 1 kg of dry diet respectively. It was detected that either the full absence of aminovitamin premix or it is high content of 30 g/kg of artificial diet lead to longer larval period duration, decreased larval survivability, cocoon and silk shell weights. It was recommended the aminovitamin premix content in the silkworm artificial diet to be from 5 g to 10 g per 1 kg of dry matter.
