As livestock farms grow in size, the number of breeding individuals increases, making it difficult to manage livestock. Livestock farms require an integrated management system such as a monitoring system, an access control system, and an abnormal behavior detection system to manage livestock houses. In this paper, a smart korean cattle livestock management system using IoT and AI technology was proposed for livestock management in livestock farms. The smart korean cattle farm management system consists of a monitoring and control system, a vehicle access management system, and an abnormal cattle behavior detection system. It is expected that this will help manage large-scale livestock houses, and additional research is needed to improve the performance of abnormal behavior detection in the future.

Objective: The preference evaluation of cattle is an important factor for estimation and improvement of the grazing amounts of newly introduced or bred grasses or cultivars in barn. This study was performed to assess the grazing behavior (the amount of grazing and/or the grazing speed) of cattle as indirect method using newly bred Brachiaria ruziziensis tetraploid strain 'OKI-1'(BR) hay as treatment group and Cloris gayana 'Callide' (CG) hay as control group. It also compared the feasibility of using behavioral differences between two groups as one criteria for evaluating preference by Japanese black cattle in barn. Methods: Three experiments were carried out using 12 growing Japanese Black cattle including 6 males and 6 females. In each experiment, the four Japanese Black cattle (2 males and 2 females) were placed in separated stall and allowed to graze BR and CG in manger that was separated into two portions for about 30 min. The position and behavior of the cattle were recorded, and weighed the residual of each gay at 15 and 30 minutes after experiment start. Results: The BR was superior to CG in chemical composition such as protein, fibers and non-fibrous carbohydrate. The cattle, over all, tended to prefer BR over CG in the first half 15 minutes in terms of the time spent and amount of grazing. Additionally, growing cattle exhibited neophilia for BR bred newly. Conclusion: These findings indicated the current approach could be applied for one of criteria to evaluate the preference of hay by Japanese black cattle under indoor housing environment.

Recently, the u-IT applications for plants and livestock become larger and control of livestock farm environment has been used important in the field of industry. We implemented wireless sensor networks and farm environment automatic control system for applying to the breeding barn environment by calculating the THI index. First, we gathered environmental information like livestock object temperature, heart rate and momentum. And we also collected the farm environment data including temperature, humidity and illuminance for calculating the THI index. Then we provide accurate control action roof open and electric fan in of intelligent farm to keep the best state automatically by using collected data. We believed this technology can improve industrial competitiveness through the u-IT based smart integrated management system introduction for industry aversion and dairy industries labor shortages due to hard work and old ageing.

In this paper, we propose a classification and theft detection system for human and livestock for various moving objects in a barn. To do this, first, we extract the moving objects using the GMM method. Second, the noise generated when extracting the moving object is removed, and the moving object is recognized through the labeling method. And we propose a method to classify human and livestock using model formation and color for the unique form of the detected moving object. In addition, we propose a method of tracking and overlapping the classified moving objects using Kalman filter. Through this overlap determination method, an event notifying a dangerous situation is generated and a theft determination system is constructed. Finally, we demonstrate the feasibility and applicability of the proposed system through several experiments.

In South Korea, mora than 90% of swine barns had open-style side wall by winch operation, and less than 5% of swine barns were semi-windowless or windowless style. The aisle ventilation system of the barn was changed to roof-wall ventilation system, and the width and the length of barns were 10~12 m and 30~50 m, respectively. The width of aisle satisfying energy save was 2~3 m. The re-modeled barns inhaled air through duct which was opened to aisle and exhaled through forced ventilation fans on the windowless wall which was accomplished by installing planks on the open wall. After remodelling, the culling ratio and energy cost were decreased from 11% (47 heads) to 3% (12 heads) and from 1,550,000 won to 730,000 won, respectively. Hence, re-modeled swine barns raising 400 heads could save 2,835,680 won during winter (from December to March).

This survey was carried out to investigate the occurrence of reproductive disorders in Korean native cattle (Hanwoo). The general management status such as barn type, feed intake, parity and type of reproductive disorders were examined in the Hanwoo farms. In this survey, the total incidence of reproductive disorders that was assessed from 54 Hanwoo farms was 11.6% (73/ 631). We first examined the incidence of reproductive disorders following herd size per farm. The rates of reproductive disorders in under 10 heads, 10 to 20 heads and over 20 heads were 25.2%, 9.4% and 8.3%, respectively (P<0.05). The rate of reproductive disorders in tie stall barn was significantly (P<0.05) higher than that in free stall barn (14.9% vs. 8.1%). The major types of reproductive disorders were follicular cysts (21.8%), fat necrosis (21.8%), and repeat breeding (17.8%). The rate of reproductive disorders assessed by the parity tended to decrease as the parity increased. The relationship between incidence of reproductive disorders and body condition score (BCS) was investigated in 203 Hanwoo. The incidence of reproductive disorder was 80.0%, 8.8%, 9.4%, 10.0%, 33.3% and 57.1% at 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 of BCS, respectively. These data show that the increase of herd size, barn type and BCS affect the incidence of reproductive disorders such as follicular cysts, fat necrosis and repeat breeding in Hanwoo.

This study was conducted to determine grazing intensity of growing Korean native goats(Capra hircus coreanae) on mountainous pasture. It was carried out to obtain basic information for improvement of mountainous pasture management and establishing feeding system of Korean native goat. A total of 20 goats were grouped by feeding systems [A mountainous pasture grazing group (Concentrated feed of 1.5% body weight, treatment 1, T1, n=10) and a barn feeding group (TMR, treatment 2, T2), n=10] to conduct study from April to September. The average forage productivity of the mountain pasture was $500.9{\pm}61.41kg/ha$. The average dry matter intake in T1 was 0.64 and the calculated grazing intensity was 21 head/ha. In productivity, when the two treatments(T1, T2) were compared, the dry matter intake was about two to three times the difference. The average daily gain per day during the experiment was 63.3 in the mountain pasture and 120 g in barn feeding. When grazing, considering mountainous pasture productivity it is necessary to increase the productivity through proper feeding. The feed costs of black goats raised by grazing on the grassland in the same period showed an average 75% reduction compared to barn feeding. As a result of this study, it can be expected that a considerable reduction of feed costs can be expected in the breeding of Korean native black goat using the mountain pasture.

Korea is currently developing country-specific emission factors to support the 2050 zero-carbon campaign. Dairy cattle represent one of the largest livestock industries in Korea, and the industry is estimated to continue increasing because of an increase in milk demand. However, country-specific emission factors for dairy cattle are currently only available for calculating methane (CH₄) emissions from enteric fermentation. Two experiments were conducted to evaluate CH₄ and nitrous oxide (N₂O) fluxes from sawdust-bedded barn in dairy cow and steer, as well as dairy cattle manure composting lots. The greenhouse gas (GHG) fluxes were quantified using the open-chamber method and gas chromatography. CH₄ fluxes from steer, dairy cow, and manure compost were 27.88 ± 5.84, 36.12 ± 10.85, and 259.44 ± 61.78 ㎍/head/s, respectively. N₂O fluxes from steer, dairy cow, and manure compost were 14.04 ± 1.27, 4.11 ± 1.57, and 3.97 ± 1.08 ㎍/head/s, respectively. The result of this study can be used to construct country-specific data for GHG emissions from manure management. Thus, the application of mitigation strategies can be prioritized based on the GHG profile and targeted source.

The trend toward intensification of livestock raising, confinement in barn has increased in recent days. The move toward concentrated animal feeding operations reduces per unit costs and permits farmers to better earnings in spite of fluctuation in hog prices. However, this also results in outbreaks of a lot of animal wastes and odorous compounds. Emissions of these malodorous compounds produced from concentrated animal feeding operations have become a concern for both public and regulatory agencies and are causing the complaints of residents in rural area. For competitive sustainable swine production industry, odor management plans systematically identify potential odor sources, determine control strategies to reduce these odors, and establish criteria for implementing these strategies. Since, the malodor originates from microbial activities involving a variety of microbes, understanding the characteristics of the microflora present in swine manure is essential for developing effective odor control techniques. This paper reviews the available information in the literature related to the types of bacteria in swine manure, the potential odorous compounds associated with different bacterial genera, and the corresponding techniques used to control odor based on microbiological principles.

This paper is purposed to develop an leakage current detecting system(LCDS) which can prevent electrical fires on breaker capacity expansion as well as ruptures of XL(Extra long) pipelines and power failure by operation of ELB(Earth leakage breaker) at auto water machine in winter. In order to develop LCDS, this paper studied field state investigation, field state experiment, development of leakage alarm system and verification experiments. Field states investigation at livestock companies(10 companies) in cheong-won location to deduce the problems of auto water machine is analyzed. The field state experiment is conducted at B livestock company in cheong won location. The field state experiment method is measured with leakage current when ELB tripped by environment factor(fine, cloudy, and rainy day). The LCDS is developed as MCU(Micro Control Unit) part applied leakage current values at B livestock company. Verification experiments for the leakage current detecting system were conducted by two methods of current supply and field test. Results show that LCDS suggested in this paper are valuable and usable in auto water machine based on environment factor, which will prevent severe damage to human beings and properties and reduce the electrical fires in livestock.
