국제적인 무역의 자유화 및 수입 개방화에 따른 각종 동물의 수입 품목 다변화에 의해 국내 농가의 소득 증대 차원에서 타조를 수입하여 사육하고자 하는 양축가의 증가에 부응하여 농림부에서 미국산 타조류 수입위생 조건을 고시(‘97.5.19)한 후 ’98.2월말 현재까지 미국, 중국등에서 약 400여수가 수입되어 사육되고 있다. 타조를 매개로하여 사람에게 치명적으로 발생되는 크리미안-콩고 출혈열의 치료 및 예방대책등을 소개하여 사육농가 및 관련 업무 종사자의 동 질병에 대한 이해를 돕고자한다.

농가마다 사정에 따라 수치의 차이가 상당히 있겠지만 앞으로 5천불 소득시대에 양계인으로 타산업과 경쟁을 할 수 있으려면 산란계 40,000$\~$50,000수의 사육규모는 되어야 할 것 같다. 종전에는 대군사육군에서 생산성이 떨어졌으나 기계화도입에 따라 환경을 제어하는 방법에 따라 소군사양방법보다는 대군사양농가에서 수익성은 더욱 높아질 것이다.

이관측은 통계전문가, 양축농가 대표 및 양축가 단체 대표 등으로 구성된 축산관측협의회에서 현재까지의 여건과 앞으로의 변동사항을 감안하여 협의, 확정된 것입니다. 그러나 앞으로의 예기치 아니한 가축질병이나 양축가의 의사변경 등 사육 여건의 변동이 있을 경우 본 관측결과와 실제 상황은 달라질 수도 있습니다.

In order to improve the present running seawater system for seedling production of marine fishes, rearing experiments with the juveniles of black seabream (Acanthopagrus schlegeli) and oblong rockfish (Sebastes oblongus) were conducted. The recirculating seawater system (F) equipped with the rotating biological contactors and the running seawater system (R) were used. Environmental factors, growth, survival rate and rearing density of the fish were compared between two systems during the experimental period. In the rearing experiment of black seabream, water temperature in F was fluctuated with surrounding air temperature and was higher than that in R. Specific gravity of the rearing seawater in F was relatively stable in the range of 1.0252 to 1.0266, while that in R was greatly fluctuated. pH in F turned out to be 7.51, but pH in R was similar to that in the natural seawater. Dissolved nitrite and nitrate in F were higher than those in R. While no significant differences in the growth of black seabream juveniles were recognized between two systems, survival rates of fishes in F were higher than those of fishes in R. In the rearing experiment of oblong rockfish, water temperature in F was higher than that in R. Specific gravity in F was slightly higher than that in R which showed relatively less fluctuation in the range of 1.0253 to 1.0270. pH in F turned out to be 7.96, but pH in R was similar to that in the natural seawater. Dissolved nitrite and nitrate in F were higher than those in R, but ammonia was lower in F. The juveniles of oblong rockfish reared in F grew significantly faster in their total length and body weight than those in R (P<0.05). However, survival rates of fishes between two systems showed no significant differences.

The approximate compositions and the taste compounds of tilapia, Oreochromis nitoticus, cultured in freshwater and seawater for six months, were analyzed. As for the approximate compositions, there were little differences in moisture and protein contents of tilapia cultured in seawater and freshwater, but somewhat higher lipids and ash than that cultured in freshwater. Also, no significant differences in the content of free amino acids, nucleoli-des, betaine, TMAO, and total creatinine were observed between both groups.

This experiment was carried out to investigate the optimal stocking rate of earthworm populations grown under different stocking rates. The stocking rate in terms of ratio of biomass of earthworms to biomass of feeds(organic resources) is an important factors for biomass productivity of earthworms and vermicast production. The different stocking rates were 1:16(S-1), 1:32(S-2), 1:48(S-3) and 1:64(S-4), as the ratios of biomass of earthworm to biomass of organic dairy cow manure, respectively. The stocking rate of 1:32(S-2) and 1:46(S-3) were obtained a higher values on increasing rates and conversion efficiency of organic matter to earthworm biomass than other stocking rates. Thus, a stocking rates of 1:32 and 1:46 estimated an optimal stocking rates for maximum biomass productivity of earthworms. A stocking rate of 1:16(S-1) showed a significantly highest values of vermicast production and ratios of vermicasts during the rearing periods.($$P{\leq_-}0.05$$) A stocking rate of 1:48(S-3) showed a highest values of the number of cocoons and vermicasts production per earthworm biomass among the treatment ($$P{\leq_-}0.05$$) The contents of nitrogen, available phosphorus, cation exchange capacity and exchangeable cations of vermicasts tended to increase with stocking rate and rearing progressed. Vermicasts have a great deal of potential for crop production and protection in sustainable organic cropping systems.

2009년 한육우 사료산업은 한마디로 비육우 양축가와 사료업계 모두 호황이었던 한해였다. "국내산 쇠고기가격의 상승"과 "사료가격의 인하"로 한육우 양축가들의 수익성은 큰 폭으로 증가하였으며, 사료업계 또한 "비육우 사육두수 증가"와 "국제 곡물가격 하락"으로 '08년 대비 수익성이 현저히 개선되었다. 이러한 상황들에 대한 올해의 국내외의 사료산업을 "비육우산업", "배합사료", "사료업계"의 3부분으로 나누어 정리하여 보았다.

Present study was to investigate the effect of dietary vegetable sources such as carrot, peahull and squash on mineral balance of Na, K, Ca, Fe, Cu, Zn and Mg in mice. It would also determine if the kind, level and feeding period of vegetables can affect the mineral balance. One hundred and thirty mice weighing $29{\sim}30g$(8 weeks of age) were randomly selected. Ten mice were fed their standard diet, and the others were divided into three experimental groups that were fed standard diet supplemented with carrot, peahull and squash. Mineral intake and urinary and fecal excretion of minerals were measured to investigate the effect of the kind, level and feeding period of vegetables on absorption rate and balance of minerals. Body-weight gain was increased in high peahull diet group compared to the control. No significant difference was observed for feed efficiency ratios between different experimental groups and urine volume was increased by vegetable fed group. Na, Ca, Fe, and Cu intake were lower in high squash-diet fed soup. K intake was higher in carrot fed mice, and Zn, and Mg intake were higher in peahull fed mice. Absorption rate and balance of mineral in control group resulted in positive balance while experimental groups showed negative. The kind of vegetable, feeding level and feeding period affected the intake of Na, K, Ca, Cu and absorption rate of Cu, Zn and balance of K, Cu, Zn to negative. In spite of the higher intake of t Zn and Mg, in experimental groups the absorption rate showed negative balance.

The performances of a parallel current air driven type foam separator were evaluated in the pilot-scale recirculating aquaculture system. The system was stocked with Nile tilapia (Oreochromis niloticus) at an initial rearing densities of $2\%$, $5\%$ and $7\%$ of water volume of rearing tank and reared for 15, 30, 35 days, respectively. The condensated volume of effluent foam was increasing with increased rearing density. As increasing rearing density from $2\%$ to $7\%$, the protein concentration in rearing tank was increased from 16.6 g/$m^3$ to 21,9 g/$m^3$ and the removal amount of protein through foam separator as increased from 0.99 g/day to 2.5 g/day. But protein concentration ratio in the foam was decreased from 3.2 to 1.9. Changes of the removal amount and the concentration ratios of total suspended solid (TSS) and chemical oxygen demand (COD_cr.) were similar to proteins. The highest concentration ratios of TSS and COD_cr. were 10.2 and 8.4 at 2$2\%$ of rearing density.
