An artificial diet, made up principally of chemicals set in agar, has given good growth in the sea hare Aplysia dactylomela Rang (13 and 29% increases in live weight in two trials of 24- and 16-day periods, respectively, at 28.5 °C). Spawn production accounted for 65 and 29%, respectively, of these increases in weight. The role that such a diet may play in the study of nutrition and feeding preferences of sea hares and of other marine invertebrate herbivores is discussed.

Dietary Components

Thirty six New Zealand fryer rabbit (bucks) averaging 874g in body weight were fed on three diets blended with 0, 7, 14% kolaunt pod meal (KPM) and10, 20, and 30% Brewers spent grains (BSG). Other dietary components included maize, soyabean meal, bone meal, salt and vitamin-mineral mixture. The trail lasted for 98 day. Significantly differences (P < 0.05) were found among the three rations with respect to daily live weight gains, feed intake and water intake. There were significant difference among the rations with respect to percent carcass yield, feet, blood and unemptied alimentary canal. However there were no significant (P > 0.05) differences among the three rations with respect to head, tail, and liver weight expressed as percentage of live weight. There was no significant treatment effect no the wholesale cuts. The chemical composition of the meat of rabbits fed 14% KPM + 3-% BSG diet was significantly lower in energy value, % moisture and % fat. The results showed that a diet fortified with 30% BSG and 14% KPM will support good growth as well as improved carcass yield of rabbits.

Improved Technique

Bioassays of Bacillus thuringiensis (Bt.) are commonly performed by applying a serial dilution of the test sample to either foliage or artificial diet (Burges and Thompson 1971). In these assays the ingested dose is not measured directly, but is assumed to be proportional to the concentration of the sample applied to the diet. This assumption is valid only if the total amount of food ingested during the experiment is the same at all dosage levels. However, this assumption may not be true because Bt. inhibits feeding of some lepidoptera larvae (Burges and Thompson 1971). Furthermore, artificial diets usually contain nutrients and possibly antimicrobial agents which may interact with Bt.
