1세부과제: 한우 비육 시 조사료 이용성 증대 사료비 절감 기술
Purpose&Contents
This experiment was carried out to reduce feeding cost and fattening period by feeding a lot of IRG silage or corn silage compared to general feeding in former fattening stage of Hanwoo steers.

Results
The body weight gain of feeding a lot of silage in former fattening stage was 0.887kg / 170.7days, meanwhile the control piot body weight gain was 0.986kg. The experimental plot body weight gain less 0.099kg than the control.
The concentrates ration of the experimental plot was less 33.3% than the control, but feeding cost was 5.7% high.
This experiment result would be evaluated with dressed weights and carcass etc after more than one year, because a dressed weight and meat quality could be measured after slaughter.

Expected Contribution
It is expected to increasing feed ration and body weight gain for late fattening stage. because experimental plot cattle ate a lot of silage 20kg/herd during early fattening stage.

2세부과제: 한우 비육후기 바이패스 기능성 사료급여 증체율 향상기술
Purpose&Contents
The study was aim to observe the effects of functional feed supplementation during late fattening on the growth rate and carcass traits of Hanwoo steers.

Results
During the late fattening of Hanwoo, The feed efficiency and carcass characteristics(reduction in backfact thickness and decrease eye muscle area) were improved by the addition of by-product of agriculture(potato)

Expected Contribution
It is expected to improve the weight gain and carcass characteristics by feeding functional feeds(byproduct, potato) on late fattening Hanwoo

3세부과제: 한우 단기비육 프로그램 적용 기술
Purpose&Contents
This study was carried out to early shipment and reduce feed costs by using agricultural by-products adding TMR to Hanwoo steers

Results
Reduced feed costs were 115,385won/5month/head and as the length of fattening increased, the feed cost decreased. Body weight gain was 0.91±0.13kg/day/head

Expected Contribution
This skill could be controlled nutrition by stages of growth and improve early shipment and reduce feed costs in the Hanwoo steers.

4세부과제: 송아지 성조절을 위한 정액의 중조 처리 기술 활용
Purpose&Contents
Technique to improve the production of female calf by treatment with sodium bicarbonate on artificial insemination of frozen semen

Results
Result of artificial insemination with sexed frozen semen treated with sodium bicarbonate were showed 60.6 % (140/231) on pregnancy rate.
This result is not final one, because AI performing was so late in this year and it will be try to diagnose the pregnancy in next year.

Expected Contribution
Through the technique of improving the sexed calf, farmers are affected to effective management of herds and farm business

5세부과제: 젖소 사료 내 메티오닌-비타민 E 복합제제 첨가 산유량 개선
Purpose&Contents
This study was conducted to improve productivity by feeding dietary methionine and vitamin E combination to reduce stress before cow calving in summer.

Results
As a result of feeding dietary methionine – vitamin E combination preparation, the mean milk yield of the participating farms was improved by 4.34%. Also, the milk fat percentage was improved by 6.3%, the milk protein ratio by 0.6%, and the solid fat ratio by 1.8%.
And the delivery interval decreased by 2.1%. The daily dietary intake of dairy cattle was 37 kg / d for Eumseong farm, 39 kg / d for Gochang farm and 36 kg / d for Yecheon farm. There was no significant change in feed intake before and after the addition of the methionine-vitamin E combination preparation in the feed, and there was an opinion from participating farmers that the feed intake did not decrease even in high temperature summer.

Expected Contribution
Milking Cows are fed methionine-vitamin E complex before delivery, resulting in increased appetite and increased feed intake. In addition, cows can maintain high-temperature production in summer.

6세부과제: 피트돈사 내 수용성 탄수화물과 미생물제 공급 냄새저감 기술
Purpose&Contents
In this study, water - soluble carbohydrates were injected into pig slurry and microorganisms in pigs were diluted to reduce odor in poultry farms.

Results
In the slurry python, a microbial salt diluted solution was added and water-soluble glucose was added to the bottom slurry. Ammonia content in pigs decreased by 48.9% from 13.3 ppm (untreated) to 6.8 ppm (treated), while amine decreased by 39.9% from 32.6 ppm to 19.6 ppm. The temperature of the pile slurry decreased by 31.7% from 28.1 ℃ (untreated) to 19.2 ℃ (treated), and the pH was not significantly different from 6.89 to 6.81.
The amount of ammonia gas in untreated slurry pellets of microorganisms and water – soluble glucose was 45.0ppm when pigs were fed, but the free pans after shipping increased by 29.6% to 58.3ppm and amine gas increased by 61.4% from 104.3ppm to 168.3ppm.
Ammonia gas was 5.2ppm in the pigs fed and 5.7ppm in the empty pigs after the dilution of the drinking water of the microorganism and the feeding of the pesticide slurry of the water soluble glucose. Amine gas was found to be 19.7ppm during the breeding and 29.3ppm for the empty pigs after shipment.
The total daily intake of microorganism-diluted drinking water was 5,174 liters for 120 to 180-day-old pigs reared on an area of 1,000 square meters. The average daily intake of drinking water was 5.75 liters.

Expected Contribution
Reduces manure odor by feeding water-soluble carbohydrates to the bottom slurry of pigs and microbiological dilution in drinking water, and improves the productivity of pork fattening.

7세부과제: 난축맛돈 뒷다리 뼈 없는 발효생햄 및 소시지 제조기술
Purpose& Contents
Bone-free hind legs fermented ham (8 months required), which has a shorter production period than the existing bone-backed fermented ham (more than 15 months) with bone in pork, reduces the processing time of meat products. When manufacturing fermented sausages, use the shiitake mushroom powder instead of synthetic antioxidants and antimicrobials to increase the safety of meat products.

Results
The error of measurement value of normal farm was high at 2.4 ℃ in the temperature setting value of fermenter during bone - free ham production, but the error of measured value of the experimental farm was low at 0.3 ℃. The error of the measured value of the general farm was 9.1% compared to the set value of the humidity in the fermenter. However, the error of the measured value of the experimental farm was 0.12%. The redness of the 95 - day fermented ham was the highest at the pork belly at 12.68. Fatty acidity was the lowest 0.52 in hind legs and the highest value was 1.09. The overall sensory scores were 5.2 for the hind leg, 3.2 for the sirloin and 2.6 for the pork belly. The fermented sausages and bone - free fermented sausages with high value added by using non - preferred parts of pork were the first to find optimum fermentation conditions and fermentation period for local environmental conditions and fermentation facilities.

Expected Contribution
We create added value by commercialization of fermentation processing parts of pork non-preferred parts.

8세부과제: 이탈리안 라이그라스 봄 파종 재배 생산성 향상 기술
Purpose& Contents
This study was conducted to improve the productivity of forage crops of Italian Ryegrass(IRG) by spring seeding of winter feed crop seeds in areas where wintering is not possible or in which timely sowing is not possible.

Results
The spring sowing time of IRG for winter feed crops was in the unmanned helicopter. The early spring sowing occurred in the period of 2.3～2.13, and the normal spring sowing occurred in the 2.14～2.24 period. According to regional IRG spring sowing, forage yield was the highest at 16～18 ton/ha in Damyang area. 50～57% (April 30) of Anseong and Jeongup areas died due to freezing damage. Early spring sowing was 10～18 ton/ha and general spring sowing was 7～16 ton/ha in the production of forage according to the spring sowing time of IRG.

Expected Contribution
The spring sowing of Italian Ryegrass in response to changes in climate change and growing conditions will ensure the safety of cultivation and improve the productivity of forage crops.
