The objectives of this experiment were to study the effect of chicken hypophyse gland exttact for spawning of carp. Each twenty female of about 2950-3050 g/head and 100 of male carp of about 300-350 g body weight/head were used in the experiments. Hypophyse gland extract were prepared from the hypophyse glands of broiler chickens of about 10 days old. As treatments, the extract was injected in five different doses of 200, 400, 600, 800 and 1000 mg/kg body weight. Each dose was injected twice. The second injection was done after 1 hours. Each treatment consisted of 4 replications as block. Parameter measured included: egg fertility, egg hatching rate and survival rate of larvae, water qualities (temperature, dissolved 02. free CO2, NH3 content and pH). Data were statistically analyzed by variance analysis in randomized block design (RBD). Results indicated that injection of broiler's hypophyse gland extract gave highly significant (P < 0.01) effect on spawning egg fertility, egg hatching rate and survival rate of carp larvae of three days old. The optimal injection dose was found 582 mg broiler's hypophyse gland/kg carp body weight.

The life cycle of earthworm Perionyx excavatus in the faces of livestock animals has been studied and had potency to depredate the animal wastes through vermiculture process. Optimal live environmental conditions were needed to achieve the optimal vermiculture process. The rate of growth and reproduction of the worm depended mainly on the availability of nutition in the medium. In this experiment, four different animal feces were used as vermiculture media, e.g. cattle, horse, rabbit and chicken. The increase of body length was measured as the growth rate function of the worm P. excavagatus. The change of temperature, pH and humidity of medium were measured as the factors affecting the growth rate. These factors were important in research objectives, i.e. production of earthworm biomass for poultry feedstuff and of high quality biofertilizer by using animal wastes as vermiculture medium. Feces of cattle and rabbit were found the best medium of vermiculture. P.excavagus cultivated in the feces of both animals showed the fast similar growth rate. The growth rate of P.excavagus in four different medium could be ordered as follows: cattle feces> rabbit feces>horse feces. Feces of chicken was found not suitable for earthworm media because of low pH. Biofertilizer from the vermiculture could be produced in relatively short time period with better physical characteristic in compare to the normal biofertilizer.

This paper discussed the potency of kampong chickens as the main source of employment and income in West Sumatra. From about 2 millions of Indonesian kampong chickens in 2005, about 5.725.515 were found in West Sumatra. In terms of egg production, body weight gain and feed utilization efficiency, the productivity and biological performances of kampong chickens were much lower than that of hybrid chickens. On the other hand, the product of kampong chickens, e.g. egg and meat, in the market were normally valued higher by the consumers because of their better taste and healthier product. In addition, kampong chickens could be intensively reared in lower production cost because of their lower nutritional and management requirements. Results of some studies has shown that production of kampong chicken might be directed for business unit as back yard or intensively farming especially in supporting of economic development in the rural community.
