삼투압 조절이 불량환경하에서의 Italian ryegrass 와 수수의 생산성에 미치는 영향

허삼남 ( S . N . Hur ) 한국축산학회 1991 한국축산학회지 Vol.33 No.1

Seeds of Italian ryegrass and sorghum were osmoconditioned with 20% PEG (polyethylene glycol-8000) solution for two days at 10℃. Effects of osmoconditioning on the growth of Italian ryegrass and sorghum in suboptimal conditions were measured. The results obtained are summarized as follows; l. Seedlings of Italian ryegrass were severely affected by drought stress, while sorghum seedlings got stress under humid tension. Osmoconditioned seeds of Italian ryegrass showed good establishment and increased dry matter yield by four or six percentages and PEG treated sorghum yielded 4-16% more than non-treated. 2. Osmoconditioned sorghum plants were accelerated in growth and yielded 16% more under chilling condition with no effect of osmoconditioning in Italian ryegrass. 3. Italian ryegrass showed a strikingly superior salt stress-resistance by osmoconditioning yielding 32% more dry matter than non-treatment under 3 mmhos/cm salinity level.

최순호,김원호,허삼남 ( S . H . Choi,W . H . Kim,S . N . Hur ) 한국축산학회 1998 한국축산학회지 Vol.40 No.5

This study was conducted to determine the productivity of Chicory (Cichorium intybus L.) as forage sources. It was the study on the productivity of Chicory imported from Newzealand under Korean soil and environment. The chicory sown on the August 15 1995 grew rapidly as temperature went up high during the spring in Korea. The yield was 44.6 ton fresh weight/ha when harvested on the 10 June, 1996. Feeding value of Chicory appeared to decrease rapidly as the plant grew older. The contents of crude protein, ash, Ca, P, and Fe of chicory were decreased from 20.8 to 12.68%, 23.06 to 12.17% 0.53 to 0.38% 0.54 to 0.25 %, 424 to 117ppm, respectively, when they were harvested in from May 20 to June 10.

Seeds of Rigitaeda pine tree (Pinus rigida × P. taeda) was primed with polyethylene glycol (PEG-6000) under different PEG concentrations, treatment period, and temperatures to test uniformity of germination. Coated seeds and PEG treated seeds were sown to compare germination, emergence, establishment, and seedling growth. The results obtained are summarized as follows : 1. As the concentration of PEG increased, as total germination percentage of pine tree was increased. Total germination percentage of pine tree seeds primed with PEG at 15 or 20℃ was better than the seeds treated at 10℃ compared to untreated seeds. 2. Germination rate was improved as primed period long and level of PEG concentration high. 3. Maximum germination rate was high with long PEG treatment period, and markedly improved when the seeds were primed at 20℃ 4. Priming with PEG at 20℃ for 12 days reduced time taken for germination. 5. Osmoconditioned seeds accelerated germination under drought condition with injurious effect of coated seeds by some chemicals. 6. There were much differences in establishment and dry matter production between drill and oversowing method, and primed seeds showed better performances than the coated seeds. Coating effects to seeds were better under drought soil condition rather than moderate moisture condition.

Lanthanum을 비롯한 17가지 특수 원소를 일컬어 희토(rare earth)라 한다. 본 연구에서는 육계사료에 희토의 첨가 효과를 알아보기 위하여 2회의 사양 시험을 실시하였다. 시험에 이용한 희토는 순도 99% 이상의 염화 희토 혼합물$(RECl_3)$로 $LaCl_3$ 36.52%, $LaCl_3$ 28.14%, $PrCl_3$ 11.24%, 그리고 기타 희토원소 24.11%로 구성된 흰색 분말 형태이었다. 희토 급여 사육기간은 5주간이었으며, 본 연구의 주요 목적은 희토 급여가 육계의 성장을 촉진할 수 있는지, 유해성은 없는지, 그리고 적정 사료 첨가 수준을 구명하였다. 육계의 복강 지방 축적에 대해서도 알아보았다. 첫 번째 사양 시험에서는 시판 배합 사료에 대한 희토 첨가 효과를 검토하였다. Cobb육계 1일령 병아리 360수를 사용하였으며, 사료에 희토를 0, 100, 200, 400, 800, 그리고 1,600 mg/kg 수준으로 첨가하였다. 육계의 성장은 희토 100 mg/kg 첨가 수준에서 가장 우수하였으며, 증체량은 대조구에 비해 8.9%가 증가하였고(1,669.9 vs. 1,533.8 g/chick), 사료 요구율도 낮았다(p<0.05). 희토는 1,600 mg/kg 수준으로 매우 높게 급여할지라도 성장이 저해되지 않았으며, 대조구와 같은 증체와 사료 요구율을 보였으므로, 과다 급여에 의한 중독증은 없을 것으로 사료되었다. 두 번째 사양 시험은 실험 1의 결과에서는 육계사료에서 성장능력의 극대화를 위한 희토의 적정 첨가 수준이 $100\sim200mg/kg$으로 예측되었으므로 좀더 근접한 적정 수준을 알아보고자 희토를 0, 50, 100, 150 mg/kg 수준으로 첨가하였다. 시험 사료는 시판 사료에 있을 수 있는 항생제나 기타 성장 촉진용 사료 첨가제를 첨가하기 위하여 자가 배합하였으며, Ross육계 1일령 병아리 360수를 이용하였다. 시험 결과 희토 50 mg/kg의 첨가가 증체량과 사료 요구율에서 대조구나 다른 처리구들에 비해 월등히 좋은 결과를 나타내었다(p<0.05). 이 시험에서는 첫 번째 시험에서 보이지 않았던, 생체중에 대한 복강 지방 비율이 현저하게 감소한 것으로 나타났다(p<0.05). 본 실험 결과 육계사료에 희토의 첨가는 육계의 성장을 촉진하였으며, 사료 요구율 개선하였다. 이외에도 복강지방이 낮아지는 경향을 보였지만 일관성이 없었으므로 추후의 연구가 필요하다. In order to study the effect of feeding rare earth(RE) on growth of broiler chicks, feed conversion ratio, and probable harmfulness of feeding high levels of RE, two feeding trials with broiler chicks were conducted; one using a commercial broiler compound feed and the other using a self mixed feed excluding any growth stimulating feed additives. The the first trial used three hundred sixty of one day old Cobb broiler chicks for six levels of dietary supplementation of RE : 0, 100, 200, 400, 800 and 1,600 mg/kg. There were significant effect of RE stimulating broiler chick growth and improving feed conversion ratio, The dietary supplementation of RE at a level of 100 mg/kg was the best of all and increased body weight gain by 8.9% (p<0.05). Chicks fed RE at a level of 1,600 mg/kg grew as good as chicks fed feeds without RE and did not show my abnormalities. The second feeding trial was conducted in the same manner as the first trial using Ross broiler chicks and self-mixed experimental diets supplemented with RE at levels of 0, 50, 100 and 150 mg/kg. Differently from Results of the first trial, body weight gain and feed conversion ratio of were the best at the level of 50 mg/kg RE supplementation(p<0.05). In this trial all the birds fed RE showed significantly lower ratio of abdominal fat against live weight than those of the control group birds. Overall, it can be said that dietary supplementation of RE will improve broiler growth and feed conversion ratio and the proper dietary level would be $50\sim100mg/kg$. These results suggested that the proper level of RE for broiler chicks would be 50 to 100 mg/kg and its effectiveness is varied depending upon RE mixture. There appears abdominal fat of broiler chicks is decreased by feeding RE but further investigation is in need.

희토(稀土)의 급여가 종계의 산란율 및 부화율에 미치는 영향

희토(稀土) 또는 rare earth(RE)라고 하는 것은 15개 란탄족 원소와 이트륨(Y) 그리고 스칸듐(Sc)을 합친 17개 원소를 총칭하는 화학 용어이다. 일부 희토 원소들의 생화학적 작용과 생물학적 기능이 인정됨에 따라, 산란계와 종계에 대한 급여 효과와 급여 수준을 알아보기 위하여 평사에서 산란초기 육계 종계(Ross SP) 16,231수를 대상으로 염화 희토 혼합물$(RECl_3)$을 가지고 30주 동안 사양 시험을 실시하였다. 본 시험에서 희토 사료 첨가는 300 mg/kg와 600 mg/kg, 두 수준이었는데, 후자는 여러 가지 시험 결과로 미루어 적정 첨가 수준을 초과하는 양으로 생각되었으며, 희토 300 mg/kg의 사료 첨가는 종계의 생산 능력을 크게 개선할 수 있는 가능성을 보여주었다 희토 급여 초기 약간의 스트레스가 있는 듯 하였으나, 피크 산란율에 도달하는 기간을 단축하고, 피크 산란율을 높게 그리고 길게 지속하는 효과가 있었으며, 산란 곡선의 탄력을 좋게 유지하였다. 희토 300 mg/kg의 사료 첨가는 부화에 이용할 수 있는 종란 생산을 3.5% 정도 증가시켰다. 또 하나 관찰된 괄목한 만한 결과는 희토가 종계의 폐사율을 크게 감소시켰다는 사실이다. 희토 사료 첨가는 숫 종계 폐사율을 33.2% 그리고 암 종계 폐사율을 46.5% 감소시키었다. 희토의 난질에 대한 괄목할 만한 효과는 관찰되지 않았다. 난각의 색이나 두께와 강도, 난황색 등은 대조구나 처리구 간에 차이가 없었고, 난중, 난백고, Haugh unit등은 유의하게(P<0.05)는 개선되는 경향을 나타냈다. 희토 급여의 수정을 및 부화율에 대한 본 시험의 결과는 기대했던 바와 같은 개선은 없었다. 34주령, 38주령, 그리고 50주령 모두 3회에 걸쳐 부화 시험을 실시하였는데, 38주령 때에만 소폭 유의한 수정율과 부화율 증가가 나타났고(P<0.05), 전체적으로는 대구나 희토를 급여한 것이나 차이가 없었다. 이 현상은 희토를 급여하지 않은 대조구의 계군에는 숫 종계 폐사율이 높아 대조구에는 혈기 왕성한 젊은 수탉이 지속적으로 편입된 반면, 희토를 급여한 계군에는 노계 수탉이 수용되어 번식능력이 낮았을 것으로 사료되므로 올바른 비교가 될 수 없을 것으로 생각되었다. 본 시험의 결과 종계 사료에 희토의 사료 첨가로 종계의 빠르고 높은 산란 피크 도달과 향상된 산란 지속성 유지, 그리고 현격한 종계 폐사율 감소 등 생산성을 개선하는 효과가 있음을 보여주었다. 그러나 희토가 수정율이나 부화율에 미치는 영향은 앞으로 좀더 연구가 필요하다. To investigate the effect of feeding rare earth (RE) on the performance of breeder hens a feeding trial with sixteen thousands of 158 day old Ross broiler breeder hens was conducted for thirty weeks. A mixture of RE- chlorides containing mainly La, Ce, and Pr was mixed into corn-soy based diet at two levels, 300 and 600 mg/kg, All the hens were housed in flat layer houses and the ratio of male to female was maintained at one to ten. Dietary supplementation of the of RE at a level of 300 mg/kg made the hens reach egg production peak higher by about 6% and earlier by about two weeks. As a result, it made higher hatchable egg production by 3.5%. It also reduced dramatically the mortality of both male and female breeders(P<0.05). Egg weight was slightly increased but egg qualify was not much influenced by dietary supplementation of RE. Egg albumin hight and Haugh unit were significantly improved while egg shell thickness, egg breaking strength and yolk color were similar to those of the control. Experimental results appeared to show a good possibility that egg fertility and hatchability were improved by feeding RE. Dietary supplementation of RE at a level of 300 mg/kg should be acceptable but not the 600 mg/kg level for breeder hens. Further studies on the effect of RE on egg fertility and hatchability appears to be necessary.

In order to investigate effect of chicory as a roughage source for Korean native goat, studies on growth rates and carcass qualities of 21 male Korean native goats fed chicory have been conducted for 6 weeks. For the investigation, their feed intakes, body weight gains, carcass weights and carcass qualities were measured. 1. The Korean native goats fed chicory tended to grow faster than those fed with orchardgrass alone (41.0g vs 35.2 g/daily gain). When chicory was fed together with orchardgass at a ratio of 50 to 50, the goats appeared to grow even faster (53.6g/daily gain). 2. Feed intakes(㎏/day) were 0.72, 0.58 and 0.56㎏ respectively for the goats fed chicory, orchardgrass, and the mixture of chicory and orchardgrass. 3. Chicory feeding tended to improve feed conversion ratio, compared to orchardgrass (13.7 vs 20.3). 4. Dietary chicory tended to impair the tenderness and juiciness of the goat meat, but seemed to make meat flavour distinct.

許三男,朴弘錫,白泳基 全北大學校 附設 畜産開發硏究所 1988 畜産開發硏究報告 Vol.2 No.-

In an effect to study experimental animal farms of universities for student practice and faculty teaching purpose, current situation and future development plans of 8 national and, 5 private universities, and 6 agricultural junior colleges were investigated. Results were as follows :1. In general, many of the university farms were too small in size or not funded enough to carry out its own function as for teaching and student practice as well as research. Man power for the farm management was also in very short supply. 2. Number of animal breeds and heads, and their productivity were far below than what they supposed to be, mainly due to the short support of the farm by the gocernment of the university. 3. Farm buildings, facilities and farm land for forage production were also very old and poor. 4. One of the major limitations against university experimental farm operation was the government or the university regultion that requested a certain level of income to be returned out of the farm operation. 5. Having above mentioned problems and not properly supported by the government or universities, all the personal who were in needs of using experimental farm at the univerrsity had a strong desire to have a minimum size of experimental farm at least for teaching, student practice and ressarch. 6. To maintain an experimental farm to be functioned as desired the urgent needs of Chonbuk National University's animal farm were estimated to have farm buildings, facilities and animals with proper amount of operating funds to maintain, 40 ha of farm land including grassland, 35 dairy cows, 10 of each beef and korean cattles, 120 pigs, 1500 chicks, 10 sheep, 10 goats and 100 rabbits.
