  • The purpose of this study is to evaluate the reduction effect of microbially activated peat on odor generated by livestock farms. The odor gas was measured by stirring the livestock manure sample with the existing litter and the microbially activated peat (Healtha Peat) was developed by this research team. In outdoor farm experiment, the measurements were performed by comparing broilers farm using rice husks and microbially activated peat as litter. The weight, mortality, shipment date, and odor levels (NH3) were measured before and after experiment. The result showed that NH3 levels were reduced by 100% in the Healtha Peat mixed group, Healtha Peat and rice husks mixed group. In the peat mixed group, Healtha Peat and saw dust mixed group showed reduce value at 99.6% and 99.1%, respectively. However the rice husks mixed group and saw dust mixed group showed a relatively weak NH3 reduction effect with values of 57.5% and 84.8%, respectively. After 3 months, the Healtha Peat mixed group and Healtha Peat and rice husks mixed group showed the highest NH3 reduction effect persistence. In the outdoor farm experiment, NH3 was present in farms using rice husks, but not in farms using Healtha Peat. In farms using Healtha Peat, the mortality and NH3 were reduced by 75% and >90%, respectively. The average body weight increased 18% and resulted to 10% decrease in the shipping date. These results implied that microbially activated peat has a clear effect on farm NH3 reduction and affects the productivity of farm animals.

  • Beef production extends over almost half of Australia, with about 47,000 cattle producers that contribute about 20% ($A12.7 billion gross value of production) of the total value of farm production in Australia. Australia is one of the world's most efficient producers of cattle and was the world's third largest beef exporter in 2016. The Australian beef industry had 25 million head of cattle in 2016-17, with a national beef breeding herd of 11.5 million head. Australian beef production includes pasture-based cow-calf systems, a backgrounding or grow-out period on pasture, and feedlot or pasture finishing. Feedlot finishing has assumed more importance in recent years to assure the eating quality of beef entering the relatively small Australian domestic market, and to enhance the supply of higher value beef for export markets. Maintenance of Australia's preferred status as a quality assured supplier of high value beef produced under environmentally sustainable systems from 'disease-free' cattle is of highest importance. Stringent livestock and meat quality regulations and quality assurance systems, and productivity growth and efficiency across the supply chain to ensure price competiveness, are crucial for continued export market growth in the face of increasing competition. Major industry issues, that also represent research, development and adoption priorities and opportunities for the Australian beef industry have been captured within exhaustive strategic planning processes by the red meat and beef industries. At the broadest level, these issues include consumer and industry support, market growth and diversification, supply chain efficiency, productivity and profitability, environmental sustainability, and animal health and welfare. This review provides an overview of the Australian beef industry including current market trends and future prospects, and major issues and opportunities for the continued growth, development and profitability of the industry.

  • The main objective of this study was to present data on the current situation and future trends of pig meat production in the European Union-27 (EU). Pig production has played an important social and economic role for centuries in many states of the EU. In 2022, pig meat production in the EU reached 23 M tons, which represented 21% of total production worldwide. The two key reasons that justify such amount of pork produced, are the acceptance and high consumption of the meat by the local population and the high quality of the meat produced which facilitated pork export. However, current data show a reduction in pork production for the last three years, as a consequence of a series of events that include i) problems with the chain of ingredients supply, ii) uncontrolled increase in African Swine Fever (ASF) outbreaks, iii) fast recovery of pig production in China, iv) increasing concerns by the rural population on the high cost to meet future requirements of the EU legislation on farm management, environmental sustainability and animal welfare, v) increased cost of all inputs involved in pig production and vi) limited interest of the new farmer generation to work on the pig sector. Consequently, pork production is expected to decrease in the EU for the next years, although sales will be maintained at a relative high level because pork is the meat preferred by local consumers in most EU countries. In order to maintain the favourable position of the pork industry in the near future, strategies to implement include: i) maintain the quality of the meat destinated to export markets, ii) improve the control of outbreaks of ASF and other swine diseases, iii) implementation of technological innovations to improve working conditions making more attractive to work in the pork sector of the food chain to the new generation of farmers and workers.

  • 일반적으로 고병원성 조류인플루엔자(HPAI; highly pathogenic avian influenza)가 발생을 하면 일정한 방역지역을 선정하여 그 범위 내의 농장에 대해서는 일괄적 살처분을 진행한다. 그러나 이러한 살처분은 산업에 막대한 경제적 손실을 줄 수 있지만, 방역 범위를 줄이게 되면 수평전파의 위험성이 커지게 된다. 따라서 본 연구에서는 국내 가금농장의 차단 방역 수준과 HPAI 발생 위험도를 측정할 수 있는 방법을 마련하고, HPAI가 발생 시 방역지역에 포함된 농장들을 선별적으로 살처분을 할 수 있는 방안을 마련하고자 수행하였다. 국내 가금농장의 계종, 규모, 지역에 따라 전국적으로 8개의 농장을 선정하였으며, 일반관리 51항목, 방역관리 106항목, 위생관리 26항목으로 총 183 항목으로 나누어 차단 방역 수준을 평가하였다. 전반적으로 산란계 농장인 5개 농장(JS, GE, CS, HS, OE)이 복지농장 (CH), 육계농장(JG, LB)보다 종합적으로 높은 수준의 점수를 획득하였다. 산란계 농장은 대부분 130점에서 157점 사이에 있는 반면, 육계농장은 45점과 75점이었으며, 복지농장은 70점 수준으로 농장간 차단 방역 수준 편차가 심하였다. 평상시 가금농장의 HPAI 발생의 위험도도 일반관리, 방역 관리, 위생관리로 나누어 평가한 후 기존의 각 농장별 현재의 차단 방역수준과 서로 비교하였다. 현재의 차단 방역 수준이 HPAI 발생 위험도보다 높은 수준의 농장의 경우 대부분이 3개 관리 분야 중 방역 관리가 뛰어나다는 공통점이 있었으며, HPAI 발생 위험도가 현재의 차단 방역 수준을 능가하는 경우에는 대부분 3개 분야의 관리가 전반적으로 취약하였지만, 특히 방역 관리수준이 매우 낮은 점수를 취득하였다. 이와 같이 본 연구에서 제시한 가금농장의 차단 방역 수준 평가를 위한 항목들을 활용을 하면 현재 가금농장의 차단 방역 수준을 평가할 수 있을 뿐 아니라, HPAI 발생에 대한 위험도를 추정할 수 있다. 따라서, 이러한 위험도 평가를 HPAI 발생시 방역 지역 내 농장에 다른 요소들과 함께 적용을 한다면 선택적 살처분의 가능성도 높아질 것으로 판단된다.

  • The meat consumption per person has continuously increased in recent years. However, the labor force in the domestic livestock industry has decreased due to the declining and ageing population. In order to increase productivity, the government have developed and distributed design standard of livestock houses. Presently, report showed that the adaptation rate of the developed livestock house design standard on the real farm was still low. Thus, this paper aimed to find ways to improve the utilization of the design standard through surveys. The survey was conducted on 650 farms across the country. Analysis of the result showed that in the poultry house, the unawareness of farmers to the design standard was found to be the biggest reason for not using the design standards. On the other hand, in the swine house, the previously built swine houses do not fit with the design standard. From these result, the following recommendations were suggested: 1) promotion and education are needed to enhance usage of design standard; 2) since it is impossible to make a design standard considering all the farm sites, it is important to consider the conditions of various farm site prior to enhancement of the design standard; 3) improvement factors such as reinforcing the ventilation design, reflecting animal welfare, preventing livestock diseases, and enhancing ICT devices can also be promoted.

  • This study conducted a survey on the recognition and demand such as recognition level, policy necessity, service demand and policy demand by supply types in order to provide the basic data for successful settlement of agro-healing services. According to the survey on awareness, 45.2% of respondents were aware of the healing farming, and 31.3% of respondents had experience in participating in the agro-healing services. 63.6% of respondents replied that they were experiencing reasons for participating in agro-healing services. Respondents who had no knowledge of agro-healing services responded that 76.7% of respondents said they would not participate. More than two-thirds of respondents in all types indicated that they needed agro-healing services. As a result of evaluating the maximum willingness to pay, there was a willingness to pay for farm work healing about 15,800 won, horticulture healing about 14,800 won, forest healing about 13,400 won, and animal assisted healing about 17,000 won. Improving accessibility and strengthening awareness were high priorities for inconveniences and improvements. 70.1% of the respondents said that policies for agro-healing services are needed. Development of agro-healing programs and contents was the first priority for support policy. The result of this study is expected to provide reference data that can be suggested for agro-healing policy establishment.

  • Objective: This research analyzed behavioral characteristics of Hanwoo (Bos taurus coreanae) steers during each season and growth stage to enable measurement of the animals' welfare level for precision livestock farming. Methods: A hundred-eight beef steers were divided into three equal groups at a Hanwoo farm according to their growth stage: growing stage (GS), 8 months; early-fattening stage (EFS), 19 months; and late-fattening stage (LFS), 30 months. Twelve behavioral categories were continuously recorded for 13 day-time hours in each four seasons with three replications. Results: Time spent standing was found to be significantly longer in summer at all growth stages (p<0.05). Hanwoos at the GS spent significantly longer standing time in spring and summer than those at the EFS and LFS (p<0.05). Lying time in summer was the shortest for all growth stages (p<0.05). Steers at the LFS spent significantly longer lying time than that at the GS (p<0.05) in summer. For GS and EFS, time spent eating in spring and autumn were longer than in summer and winter (p<0.05). Eating time was the longest for the GS in spring, autumn, and winter, excluding for the LFS in winter (p<0.05). Regarding ruminating, steers at the LFS spent significantly shorter time than those at other stages in all seasons (p<0.05). GS and EFS steers showed the longest walking time in summer compared with other seasons (p<0.05). At GS and LFS, drinking time in summer was the longest of all seasons (p<0.05). Sleeping time was significantly shorter in summer compared with the other seasons (p<0.05). Self-grooming time was the longest in winter for all growth stages (p<0.05). Conclusion: Steers were found to have more variable behavioral patterns during summer and the GS and less active behaviors during the LFS, thus extra care seems necessary during the GS, LFS, and summer period.

  • 경제동물에 대한 동물복지에 대한 관심은 전세계적으로 고조되고 있는 추세이다. 그러나, 국내 양돈농가는 경제성 등을 이유로 고려하지 않거나 미비한 도입으로 돼지 본연의 행동이 제한되고 있다. 따라서, 본 연구의목적은 일반적인 사육환경에 환경보조물의 제공이 육성돈의 행동특성에 미치는 영향을 구명하고자 실시하였다. 실험동물은 45두의 3원 교잡육성돈(요크셔${\times}$랜드레이스${\times}$두록; 평균체중, $33.35{\pm}5.5kg$)을 준비하였고, 완전임의배치법(randomized complete block design)에 의해 3개 처리구(대조구; 현수형 환경보조물, T1; 바닥형 환경보조물, T2)에 처리구당 3반복, 반복당 5두씩 반슬러리 돈방에 배치하였다. 현수형 환경보조물은 돼지의 어깨 높이에 현수하였고, 바닥형은 돈방의 가운데에 고정시켰다. 시험기간은 14일간 수행하였으며 시험종료일에 스트레스호르몬인 코티졸(cortisol) 농도를 분석하였고 행동특성은 1과 8일차에 촬영하였고 베가스 프로(Vegas Pro) 13.0 프로그램을 활용하여 및 분석하였다. 체중 및 일당증체량은 대조구와 처리구들간 차이가 없었다. 코티졸호르몬은 T2(25.28 ng/mL)에서 대조구(46.75 ng/mL)보다 유의적으로 낮았다(p<0.05). 1일차 행동 유형별 지속시간은 움직임과 공격 항목에서 대조구에 비해 처리구에서 유의적으로 낮았다(p<0.01). 8일차 놀이행동 지속시간에서 처리구2는 925.12초로 T1의 323.91초 보다 유의적으로 높았다(p<0.01). 반면에 처리구들에 비해 대조구는 움직이지 않는 시간이 많았다(p<0.01). 이러한 결과는 환경보조물 제공이 돼지간 공격성을 감소시키고 돼지의 행동을 활동적으로 만들어 돼지 본연의 행동요구를 충족시킬 수 있음을 시사한다. 그러나, 국내에서 환경보조물에 대한 연구는 미흡하므로 본 연구결과는 보조물을 이용한 동물복지에 대한 기초자료로서 활용 가능할 것으로 사료된다.

  • Equilume light masks had no impact on hastening the resumption of estrous cyclicity in mares maintained in outdoor pastures on the mainland of Korea due to the cold weather conditions. Jeju Island is a major horse-breeding site in Korea and is warmer than the mainland during the winter season. Therefore, the primary objective of this study was to explore the efficiency of the Equilume light mask on the resumption of seasonal estrous cycles in Thoroughbred mares on Jeju Island. A total of 20 nonpregnant mares were randomly divided into the Equilume light mask (n = 9) and stable lighting (n =11) groups. The experiment was performed at seven different horse-breeding farms located on Jeju Island from November 15, 2020, to February 15, 2021. The mares were exposed to the respective lights from 16:00 to 23:00. Follicle size and uterine edema were measured by ultrasound scanning. Body condition scores (BCS) were also monitored during the experiment. Statistical analysis was conducted using the SAS and SPSS software, and p-values of < 0.05 were considered statistically significant. Two of the nine (22.2%) mares in the Equilume light mask group and three of the 11 (27.28%) mares in the stable lighting group were still cycling in December and January, which were considered as all-year-round cycling mares. On February 15, there was no difference between groups in the resumption of early seasonal estrus cycle, which was determined by follicles > 25 mm in addition to uterine edema. All mares in the Equilume light mask group and five of the eight mares (62.5%) in the stable lighting group had resumed cycling. Interestingly, six of the seven mares (87.5%) in the Equilume light mask and four of eight mares (50%) in the stable lighting group had already ovulated on February 15 (p > 0.05), as determined by the presence of a recent corpus luteum. No difference was observed in BCS and uterine edema between groups (p > 0.05). In conclusion, the Equilume light mask can be an effective approach to induce early seasonal estrus cycles of mares in Jeju Island, and it also enhances the efficiency of farm management by reducing labor.
