example 1

[0019] Table 2 provides several preparation and use examples of the mixed preservative of the present invention. See Table 2 for the shelf life of the feed and the price per kilogram of preservatives.

[0020] instance number

[0021] Tests have shown that adding the mixed preservative of the present invention to the artificial feed of silkworms of silkworms can preserve them for more than 10 days. The artificial feed for silkworms without preservatives became moldy in only 2 days.

example 2

[0023] Table 3 shows the effects of different proportions of mixed preservatives on the antiseptic effect of feed and the growth and development of silkworms. In the table: A is 25% sorbic acid + 50% propionic acid + 25% carbendazim mixed preservative, added to the feed at a ratio of 0.30%; B is 30% sorbic acid + 45% propionic acid + 25% carbendazim mixed Preservatives are added to the feed at a rate of 0.35%.

[0024] preservatives

[0025] It can be seen from the results in Table 3 that when the feed addition ratio of 30% sorbic acid + 45% propionic acid + 25% carbendazim mixed preservative is 0.35%, it can be preserved for more than 10 days, and it can be used for 1-2 ages. Small silkworms are bred with artificial feed once, and the price is low. The silkworms develop neatly, grow fast, and have a high survival rate.

Abstract

The mixed preservative for the feed of young silkworm consists of sorbic acid 25-45 wt%, propionic acid 45-60 wt%, and carbendazim 0-25 wt%. The preservative of the present invention has low cost and convenient use. Test shows that the preservative has obvious preserving effect, can prolong the preserving time of feed obviously and prevent and kill fungus, and has no negative effect on the eating and growth of young silkworm.

Description

technical field [0001] The invention relates to a mixed preservative for artificial feed of silkworm silkworms. Background technique [0002] Sericulture with artificial feed is an epoch-making technological innovation in the history of sericulture. It has fundamentally changed the traditional pattern of "sericulture must first be planted with mulberry, and mulberry is grown to feed silkworm". Reasonable layout of sericulture, avoiding pesticide and fluoride poisoning, is conducive to controlling the occurrence of silkworm diseases, and is conducive to alleviating the contradiction between planting mulberry and grain and other economic crops for land and labor, and can greatly improve labor productivity and reduce labor intensity; Silkworms are used as a bioreactor to produce a variety of biological products. Artificial feed can provide silkworms anytime and anywhere for this system, which is of great significance. [0003] Silkworm artificial f...
