  • An experiment was conducted to evaluate the effects of nitrogen supplementation through urea-molasses multinutrient block (UMMB) on the performance of dairy cows fed good quality forage based diets with rice straw as a night feeding. A total of 10 multiparous crossbred dairy cows in their early lactation were grouped into two categories based on their breed, parity, body weight, milk yield, milk fat and protein contents and daily fed a chopped CO-3 grass (Pennisetum purpureum ${\times}$ Pennisetum americanum; hybrid Napier) ad-libitum, 1 kg of dairy cow concentrate feed during the day time and 5 kg of rice straw (dry matter basis) at night as the basal diet (control) for 5 wk. In addition to the basal diet, the treatment group received 300 g of crushed UMMB daily throughout the experimental period. Cows were milked twice daily and the milk yields were recorded. Milk and feed samples were collected weekly for chemical analysis. Supplementation of UMMB had no significant effects (p>0.05) on straw intake, daily milk yield, contents and yields of milk constituents such as milk fat, protein, lactose and solids-non-fat. In addition, milk urea nitrogen content were not affected (p>0.05) by UMMB supplementation. However, numerical increments in all the parameters measured were observed during the study in cows fed diets supplemented with UMMB. It can be concluded that nitrogen supplied through UMMB had no effects on production performances of dairy cows in this study.

  • This study examined carcass and meat quality parameters in growing/finishing pigs fed unconventionally versus the concentrate-based system. Ninety-six, 12 wk old pigs ($34{\pm}SD0.3kg$) were randomly divided into three groups, assigned to one of the three dietary treatments: standard complete concentrate mixture, conventional (C diet); unconventional, steamed potato-green forage-concentrate based diet (U diet), and unconventional basal diet+herbage mix (UH diet). Pigs fed U diet showed lower dressing percentage, meatiness, loin eye area, and weight of pork neck ($p{\leq}0.05$), but their carcasses were significantly ($p{\leq}0.05$) longer and had increased backfat depth ($p{\leq}0.05$). There was no impact of the diet on the meat content of dry matter, crude ash, acidity, and colour parameters of m. longissimus. Unconventional feeding significantly ($p{\leq}0.05$) elevated water the holding capacity of m. longissimus and slightly improved the sensory attributes analysis of meat. The addition of herbs resulted in increased loin eye area ($p{\leq}0.05$), decreased fat content ($p{\leq}0.05$) in m. longissimus, and tended to improve some sensory attributes of meat. There were significant gender differences in response to all diets. There were significant diet${\times}$sex interactions for some measured variables, but there were no clearly identifiable trends with regard to any specific carcass or meat parameters. Feeding unconventional diet to pigs may offer better culinary attributes of the meat, and improve some technologically important characteristics of pig carcass, but may negatively affect some carcass or meat parameters.

  • The objective of this research was to evaluate the effects of two different feeding systems on blood metabolites in Holstein heifers and analyze the economic impacts of the feeding systems. The following two experiments were conducted to investigate the effects of feeding system on blood metabolite changes in Holstein heifers and analyze the economic impacts of the two systems. In experiment 1, the effects of two different feeding systems on cortisol, progesterone, and estradiol in Holstein heifers were examined. In experiment 2, the effects of two different feeding systems on the body weights of Holstein heifers and profitability of the two feeding systems were studied. Results showed that the pasture-raised heifers showed significantly decrease in the levels of blood cortisol (p<0.05) and increases in the levels of progesterone and estradiol (p>0.05) when compared with heifers raised in indoor feeding system. The average daily gain was significantly higher (p<0.05) in indoor-raised heifers (0.73 kg/day) as compared to pasture-raised heifers (0.58 kg/day). Also, 25.2% more profits were obtained from the pasture feeding system as compared to the indoor feeding system. These results together would be useful in the investigation of feeding system and growth performance in dairy cattle.

  • The objective of this work was to evaluate the growth performance, feed intake, slaughter characteristics, meat quantity and quality characteristics of Hanwoo steers fed with Italian ryegrass (IRG) silage (TRT). IRG silage consisted 11.70% protein, 2.84% ether extract, 53.50% dry matter digestibility and 63.34% total digestible nutrients. The daily weight gain and feed conversion ratio of TRT were significantly (p<0.01) higher than that of control diet (CON; fed rice straw) in the whole periods. However, the slaughter weight, dressing percentage, quantity grade and quantity traits (marbling score, meat color, fat color, and quality grade) of either TRT or CON were similar. Meat fed TRT diet showed higher crude fat and lightness (L*) value and lower moisture content and pH value compared with the CON diet (p<0.05). Overall the carcass yield was 12.5% higher than CON diet.

  • Three fistulated nonlactating Holstein cows were used to examine the change in ruminal characteristics when fed diets of 100% corn silage, 50% corn silage + 50% wet brewers' grain(WBG) and 100% WBG, and also twenty Holstein heifers averaging 156 $\PM$ 3.2kg BW were randomly assingned to determine the adequate feeding level of concentrate with the following treatments ; Only WBG, concentrate to 0.5, 1.0 and 1.5% of BW under feeding WBG ad libitum. Tne main results were as follows : I. Ruminal pH was minimized 3 hrs after feeding and then gradually increased. The mean ruminal pH was highest in feeding only WBG (6.72) and lowest in only corn silage(6.0) 2. Ruminal $NH_3$-N concentration was maximized 1 hr after feeding and then gradually decreased regardless of diets, n7e average ruminal $NH_3$-N content was highest in diet of 100% WBG(12.9 rngldl) and lowest in 100% corn silage(5.9 mg/dl) 3. Acetic acid percent among VFA was highest when WBG replaced 50% corn silage and acetic to propionic acid ratio was higher in order of feeding only corn silage, 50% corn silage + 50% WBG and only WBG. 4. Ruminal bacteria and protozoa number in diet of 50% corn silage + 50% WBG were 8.14 $\times$ > $10^5$ and 1.45 $\times$ $10^5$, respectively, which were most of all treatments. 5. Daily gain and feed efficiency of Holstein heifer in feeding concentrate to 0.5% of BW and forage hay to about 20% of total DM intake when fed free WBG were better

  • Pollution of agricultural soil by alkaline salts, such as Na2CO3, is a critical and long-lasting problem in cultivable land. The aim of the study was to examine the putative role of citric acid (CA) in alleviating Na2CO3-stress in alfalfa. In this study, Na2CO3 significantly induced leaf chlorosis, inhibited plant growth and photosynthesis related parameters, increased hydrogen peroxide (H2O2) and reduced major antioxidant enzymes (SOD, CAD, APX) in alfalfa. However, the presence of CA these negative effects of Na2CO3-stress largely recovered. Interestingly, expression of antioxidant and ion transporter genes (Fe-SOD, CAT, APX, DHAR and NHX1) involved in Reactive oxygen species (ROS) homeostasis and oxidative stress tolerance in alfalfa. These findings suggest that CA-mediated Na2CO3 stress alleviation is an ecofriendly approach that would be useful to local farmer for alfalfa and other forage crop cultivation in alkaline soils.

  • Orchardgrass 및 white clover의 단파 및 혼파 재배조건에서 미량요소 붕소의 시비수준별 목초의 생육, 개화, 뿌리/근류 형성, 수량, 양양성분/무기양분 및 초종간 경합지수에 미치는 영향 등을 구명하였다. 다량요소 및 다른 미량요소 양분을 동일량 시비한 조건에서 5 수준의 붕소 시비량을 달리한 시비처리를 하였다. 붕소 처리수준은 1) $B_{0}$; 0.0, 2) $B_1$; 0.2, 3) $B_2$;2.0, 4) $B_3$;6.0, 5) $B_3$;6.0, 5)$ B_4$;15.0me B/pot로 하였으며, 본 I보에서는 붕소 처리별 목초의 생육, 개화, 뿌리 및 근류의 형성, 수분관리 특성 등에 미치는 영향을 검토하였다. 1. White clover에서 붕소의 과다증상($B_3$$B_4$ 처리구)은 예취 차수가 진행되어 감에 따라서 경감되었고, 전반기 예취기에는 orchardgrass보다 더 심한 과다증상을 보였다. 그리고 단파보다도 혼파재부에서 과다증상이 더 심했다. 각 초종별 생육이 왕성한 시기에는 공히 붕소의 과다증상이 경감되었다. 2. Orchardgrass에서 붕소의 과다증상은 잎의 선단 부위에 황화현상, 좁은 엽폭, 적은 분얼 및 약한 줄기를 보였으며, white clover는 고엽부터 엽변의 황화현상과 백화현상, 적은 분얼수 및 포복경을 생성하는 얼자의 미 형성이 관측되었다. 3. 적합한 붕소시비($B_2$)는 white clover의 뿌리생육, 근류 형성, 개화 및 화아가 양호하였고, 꽃의 생성기간이 길었으며 만개시기가 빨랐다. 그러나 혼파재배에서는 orchardgrass에 의한 억압된 생육 때문에 이 효과가 경감되었다. 4. 붕소의 시비효과는 orchardgrass보다 white clover에서 더 크게 나타났다. 혼파재배에서 white clover는 추비가 시비되지 않은 5차 예취시에는 처리구가 다른 처리구에 비해서 생육이 양호하였는데 이는 뿌리 및 근류의 형성이 더 양호한 특성에 기인된 것으로 생각되었다. 적합한 추비(특히 질소) 및 붕소의 시비는 양호한 식생을 갖는 grass-clover 혼파초지 조성에 크게 기여할 수 있는 것으로 보였다.

  • 본 연구는 산간지 방목이 거세한우의 성장특성 및 도체형질에 미치는 영향을 조사하기 위해 수행되었다. 시험구 배치는 육성기부터 출하시까지 일반 비육프로그램(30개월)으로 사육되는 대조구(Control)와 육성기부터 5개월간 방목후 30개월에 출하되는 처리구(TRT 1), 육성기부터 9개월 방목후 30개월에 출하되는 처리구(TRT 2) 및 육성기부터 9개월 방목 후 31개월에 출하되는 처리구(TRT 3)로 4처리 하였으며, 처리구당 한우 거세우 8두씩 배치하였고, 모든 방목 처리구는 방목기간 이후에 출하시까지 일반 비육프로그램으로 전환하여 사육하였다. 출하시 종료체중은 대조구에서 가장 높았으며, 육성기간 동안의 일당증체량도 모든 방목 처리구에 비해 대조구에서 유의적으로 높게 나타났다(p<0.02). 도체중은 대조구에서 가장 높았고, 등지방두께는 TRT 3에서 두꺼운 경향을 보였지만 처리간 통계적인 차이는 없었다. 근내지방도는 방목에 따른 일관적인 경향 없이 TRT 2에서 가장 높게 나타났으며, 등심의 일반성분 및 전단력은 방목에 영향을 받지 않았다. 육색의 명도, 적색도 및 황색도의 처리간 차이는 없었지만, 지방의 황색도는 대조구 보다 TRT 1 및 TRT 2에서 높게 나타났다(p<0.02). 방목기간이 등심의 지방산 조성에 미치는 영향은 일정하지 않았다. 따라서, 산간지 방목은 거세한우의 성장과 육질에 미치는 영향없이 육색을 저하시킬 수 있을 것으로 판단되며, 향후 초지의 품질, 생산량 및 섭취량에 대한 추가 연구가 필요할 것으로 사료된다.

  • This study aims to identify factors affecting the acceptance intention of cultivating a new Italian ryegrass(IRG) variety using partial least square structural equation modeling(PLS-SEM) and find priority to maximize the acceptance intention of new IRG variety using importance-performance matrix analysis(IPMA). The data were collected on a seven-point Likert-type from 188 farm households located in Korea central region for two months. As a major result of PLS-SEM, expected effect significantly affected acceptance intention. The IPMA also showed expected effect should be considered as the most important factor to improve the acceptance intention. This study suggested the new technology distributors should scientifically prove and actively promote the effects such as increase in farm income, productivity improvement, labor saving and management efficiency caused by planting new IRG variety.
