Attacus atlas are insects producing silk materials having high economic value. It lives from South East Asia, almost all Indonesia until Australia.The demand of silk from Attacus atlas is quite high (10 tons/month). The A. atlas silk is very exclusive, with permanent in variety colors from light to dark brown. At present, to response the high demand, the people get cocoons from nature. This action could reduce result, and the scarcity of the insect. Beside that, rearing was done by placing the larvae on the trees (outdoor rearing). The outdoor rearing resulted in high mortality because of predators or stress. Better rearing is conducted by indoor rearing, that resulted in high survival rate, and high cocoon or egg production. It is because indoor rearing was supported in better environmental condition than outdoor condition that support physiological process eficiently.

Silkworm rearing has high economical value for producing silk material and other beneficial biological materials such as enzyme, antibacterial agent, and antioxidant. For those purposes, it is important to continuously support high quality feed in the silkworm rearing.This study was aimed to evaluate study the growth of silkworm Bombyx mori fed with artificial diet containing different resources of protein (blood meal or soybean meal). The experiment used completely randomized design 5 five treatments artificial feed formulas and 20 repetitions. Each experiment unit consisted of 1 larvae that was reared individually and given different feed. Formula A: 100% blood meal (BM); B: 75% (BM) + 25% soybean meal (SM); C: 50% (BM) + 50% (SM); D: 25% (BM)+ 75% (SM); and E: 100% SM. Parameters measured were the feed consumption/larvae, opproximate digestibility, ECI (efficiency of conversion of feed ingested), ECD (efficiency conversion of feed digestibility), and body weight gain in fourth and fifth of the larvae instar. Oxygen consumption were measured on the fifth day of the fifth instar before meal and one hour after meal. The result showed that resource of protein did not significantly affect the parameters on the fourth instar, but significantly affected on the fifth instar larvae. Increment of soybean meal in artificial diet increasing oxygen consumption, and resulted decreassing of ECI and ECD value on the fifth instar larvae.

Wild silkworm (Attacus atlas) has high economic value. There is a problem in rearing wild silkworm Attacus atlas, the emergence of males and females imagoes are not the same. The aim of this research was to study the survival lifetime and the sperm of the male imago. This research used randomized design experiment, with two treatments of storage temperature (room temperature 27 °C and cool storage temperature 5 °C) and eight repetitions. Survival of male imago, sperm survival, and imago body weight had been measured. The results showed that cool temperature (5 °C) could to extend significantly (P<0,01) the survival lifetime of male imago and the sperm of male imago A. atlas up to 11.5 ± 0.7 days. There is a positive correlation between body weight and lifetime of male imago of wild silkworm A. atlas, so the lifetime of male imago is predicable from their body weight.

An experiment was designed to study the effects of curcumin and thyroxine hormone supplementation in the diet to improve the reproductive performance of catfish broodstock by improving egg quality that eventually increases the production of seedlings. Catfish used in this experiment were supplemented with curcumin and thyroxine hormone through their feeds for 12 weeks. The results showed that there was no significant difference (p > 0.05) in the hepatosomatic index (HSI), gonadosomatic index (GSI), percentage of gonad maturity, total cholesterol concentration in the spawned eggs, high density lipoprotein (HDL) concentration in the spawned eggs, fertilization rate of spawned eggs, and hatching rate of fertilized eggs. However, there were significant differences (p < 0.05) in the concentration of vitellogenin in the spawned eggs, egg diameter of the spawned eggs, and the triglycerides contents of spawned eggs. It was concluded that curcumin and thyroxine supplementations of African catfish increased vitellogenin concentrations and diameters of spawned eggs that have great potential to improve the reproductive performance.

In oviparous animals, the qualities of offspring are determined by the materials deposited in the developing oocytes that are synthesized and produced by the hepatocytes under the control of estrogen. This study was designed to evaluate the effect of turmeric powder supplementation on liver performance to support the reproduction performances of catfish (Pangasianodon hypophthalmus). The study used 60 catfish with average body weight of ± 2 kg. The experimental catfish were assigned into a completely randomized design with 4 treatments and each treatment consisted of 15 replications. The treatment was the dose of turmeric powder supplementation in the commercial feed i.e., 0, 240, 480, and 960 mg/100 g feed. The experimental catfish were fed two times a day in the morning and in the evening as much as 3% of body weight. The results showed that turmeric powder supplementation at a dose of 240 mg/100 g feed could inhibit liver cell destruction in the catfish as was indicated by the increase in body weight, liver weight, and DNA concentrations of liver, as well as the decrease in the liver malondialdehyde, and serum glutamic piruvic transaminase, serum glutamic oxaloacetic transaminase concentrations. Turmeric powder supplementation can be used in oviparous animals and fish to increase liver function and capacity to synthesize vitellogenin to be deposited in the developing follicles during reproduction phase.
