This experiment was conducted to evaluate two different types of feed additive as an alternative for antibiotics on growth performance and feed cost in growing and finishing pigs. One additive is an herb extract, with Fenugreek (Trigonella foenum graecum) as the main component, while the other feed additive contains aminolevulinic acid (ALA). In the first experiment, 128 grower pigs were allotted to 4 different treatment groups and replicated 4 times with 8 pigs per replicate; the trial lasted for 28 days. The positive control group (PC) which is the control group supplemented with antibiotics was significantly higher (p<0.05) in growth rate (580.6 g/d) followed by the ALA group (532.0 g/d), there was no significant differences in terms of feed intake and feed efficiency. There were marginal reductions in feed costs measured as feed cost per head in ALA and HE added diet. However, the feed cost per weight gain of ALA treatment was higher than the control group (PC) supplemented with antibiotics. In the second experiment, 80 finisher pigs were allotted to 4 treatment groups and replicated 4 times with 5 pigs per replicate; the trial lasted for 70 days. The treatment group supplemented with an herb extract (HE) had a significantly higher (p<0.05) feed intake (2,415.8 g/d) compared to the other treatment groups, but there was no significant differences in terms of growth rate and feed efficiency. Feed cost per head in HE and ALA treatments were higher than PC treatment, and feed cost per weight gain of HE was higher than PC treat (p<0.05). The results from these experiments suggests that these two types of feed additives can both be used as an alternative for antibiotics without having a negative effect on the performance of the animals. And aminolevulinic acid was good in performance and production cost of grower and finisher pigs.

This study examined the effects of restricted feeding on the growth performance, carcass characteristics, and economic efficiency of finishing pigs for 27 days. A total of 24 finishing pigs (Landrace×Yorkshire×Duroc, average initial body weight of 81.52±1.11 kg) were allotted randomly to two treatments with 12 replicates (one pig per replicate). The experimental treatments were ad libitum feeding (AF), and restricted feeding (RF) with a 10% increase in offered feed than the day before if required. The results showed that the average daily feed intake (ADFI; p<0.001) of the pigs were improved in the RF treatment, but there were no changes in the average daily gain and weight gain to feed intake ratio (G:F). There were no significant differences in carcass weight and backfat thickness. In addition, the total pork price per pig was not affected by RF. Although total feed intake (TFI) and total feed intake cost (TFC) were significantly lower in the RF pigs (p<0.001), the feed cost per 1 kg weight gain (FCG) was similar regardless of the treatments. In conclusion, the RF method may decrease the feed cost due to a lower TFI and TFC.

점농어, Lateolabrax maculatus는 담수적응력이 강할 뿐만 아니라 수온변화에도 강 특히 남해안과 서해안의 폐염전을 활용한 축제식 양식대상어종으로 선호하고 있는 실정이다. 다른 농어에 비해 성장이 빠르며 최근 인공종묘생산이 가능해짐에 따라 양식생산량이 증가하는 추세이다. 축제식 양식장어 적합한 점농어 전용사료가 개발되지 않아 대부분 숭어사료(Extruded Pellet, EP)를 급이 하거나 대만산 농어사료를 수입하여 급이 하고 있는 실정이다. 대만산 사료의 경우는 가격이 비싸 어민들이 기피하고 있는 설정이다. 점농어의 대량생산을 위해서는 이종에 적합한 EP사료가 개발되어야 할 것이다. 사료는 양식경영비의 절반이상을 차지하는 중요한 요소로 경제적이고 품질이 우수한 사료의 안정적 확보가 양식경영을 향상시킬 수 있다.

우리나라의 사료관련 축산기계의 발전은 벼농사용 농기계에 비하여 수요가 적고 생산업체가 영세하여 기술개발이 미흡하고 해외수입 의존도가 높다. 그러나 사료산업 기계의 발전은 60년대 소규모 인력 의존시기로부터 2000년대에는 기계화가 성숙된 자체 기술 개발 단계로 발전하였다. 지난 40년간 우리나라 사료산업 기계를 조사료생산 기계와, 사료가공 및 급이 분야로 나우어 그 변화를 살펴보고자 한다.

사료배합비 문제는 여러가지 형태의 전산기에 의해 풀 수 있다. 프로그램 FEEDMIX는 전술한 문제를 풀 때 MV8000을 이용하면 몇분대로 풀리고 중형(64KW), 소형(64KB)를 이용하면 몇시간대로 풀리고 있다. 적은 CPU 용량을 가진 중형, 소형에서 많은 시간이 걸릴 것은 당연하다. 그러나 사료배합비를 구하는 문제는 화급을 요하는 문제가 아니기 때문에 몇시간씩 걸리더라도 예를 들어 퇴근할 때 프로그램을 수행케하여 출근 때 그 결과를 받아본다든가 할 수 있을 것이다. 이런 방법으로 중형, 소형 전산기를 활용하면 대형전산기에 의뢰하여 비싼 값으로 문제를 푸는 것보다는 여러가지 편리한 점이 많을 것이다.

This study was conducted to evaluate the feasibility of food waste as a feed resources by fermentation and fermented food waste as a substitute of rat feed on the performance with measuring the liveweight gain, feed consumption, feed conversion and digestibility Sixty-two grams Sprague-Dawley line 36 rats were allocated three treatments 12 rats of each(3replication ${\times}$ 4 rats). The substitution level of fermented food waste to commercial broiler feed were control, 0: 100: treatment I, 10: 90: treatment II, 20:80. The chemical composition of fermented food waste was appeared to follows : dry matter, 88.47% : crude ash. 12.95: crude protein, 20.82%; crude fiber, 13.62; ether extract, 9.15%. The body weight of treatment I and II at 1 weeks was significantly lower than those of control(p<.05) and weekly weight gain of control at 0-1 weeks was significantly higher than those of treatment I and II(p<.05). Those were higher in treatment I than those of rest groups at 1-2 weeks(p<.05). Total weight gain of treatment II was significantly lower than those of control and treatment I(p<.05) Total feed consumption of treatment II was significantly higher than those of control (p<.05) and weekly feed consumption of control and treatment II at 3-4 weeks was significantly higher than those of treatment II(p<.05). but those were higher in treatment I and II than those of control at 2-3 weeks(p<.05). Commutative feed conversion of treatment II was significantly higher than those of control(p<.05) and weekly feed conversion of treatment II and III at 0-1 weeks was significantly higher than those of control(p<.05) Dry matter digestibility of control and treatment I was significantly higher than those of treatment II(p<.05) and organic matter digestibility was higher in control than those of treatment II(p<.05).
