Abstract


The goal of our research is to organize an experiment with 3 variants of silkworms. The biological material was
represented by a single silkworm breed: Baneasa 75 (B75), in order to obtain the best genetic uniformity. Only
environmental conditions (feeding) were different. This research present the influence OF 2 supplements on serigene
glands weight at Vth age of larva. Spirulina and Spirulina with Sea Buckthorn extract capsules provided from S.C
Hofigal Export-Import S.A. Spirulina is a rich source of proteins, contains a wide range of aminoacids, fatty acids,
vitamins ( biotin, tocopherol, thiamine, riboflavin, niacin, folic acid, pyrodozoic acid, beta-carotene and vitamin B12),
vegetal hormones, enzymes, microelements, biological pigments. Sea Buckthorn extract is a very rich source of
vitamins ( vitamins A, E, C, P, carotenoids and B complex), microelemnts (phosporus, calcium, magnesium, potasium)
and fatty acids. Regarding the sericigene gland weight we can observe that the mean values of the variant treated with
Spirulina (S) and the variant treated with Spirulina with Sea Buckthorn extract (S+SB) are higher than the control.
