It is imperious to know the reproductive parameters of the subsisting swine breed for profitable farming in Bangladesh. This study was designed to compare the reproductive parameters of sows at hilly areas between the local and crossbred at farm and backyard level. A total of 116 breedable sows were included. The data on age at puberty, litter size, birth weight, weaning weight, gestation length, interval between farrowing and number of piglets born per sow in local and crossbred sows were determined and direct questionnaire method was used for data collection. The present study revealed that age at puberty between farm and backyard system of crossbred sows was $8.88{\pm}0.153$ and $9.85{\pm}0.221$ months, respectively. The farrowing interval was shorter in crossbred sows which were kept in farming system rather than backyard system. The interval between farrowing and onset of estrus was shorter in crossbred sows. The gestation length was almost similar between backyard and farm condition. The number of litter size per sow per farrowing was $8.45{\pm}0.41$ in crossbred and $7.17{\pm}0.250$ in local pigs at backyard system. The birth weight and weaning weight were more in farm conditions than backyard system. The age at puberty in local breed was lower than the crossbred and litter size was $8.45{\pm}0.407$ in crossbred which was higher than local breed $7.17{\pm}0.250$ in backyard system. These results suggest that reproductive parameters of local sow need to be improved for better production and crossbred sows should be reared for obtaining desired productivity.
This study examined the effects of cage rearing system and backyard raising system on fatty acid profile of egg in laying hens during 9 weeks. Two hundred hens, 70-wk-old, Hy-line Brown, were used in this study and fed basal diets. 100 hens, randomly collected from facility, were transferred to cage rearing system and 100 remaining hens were moved to backyard raising system. For overall period, higher unsaturated fatty acid percentages in two different rearing systems than did saturated fatty acid (SFA) were observed. In unsaturated fatty acid compositions, both rearing system showed a higher mono unsaturated fatty acid (MUFA) contents than poly unsaturated fatty acid (PUFA) contents. Egg quality traits of laying hens reared in backyard system had considerably lower contents of SFA and higher contents of MUFA compared with eggs from cage rearing system (P<0.05). In addition, eggs from cage rearing system resulted in a significantly lower n-3 contents and higher n-6:n-3 ratios and CLA contents in comparison with backyard raising system (P<0.05). However, no significant effects of two different rearing systems on PUFA, PUFA:SFA ratio, and n-6 contents were observed during the experimental period. In conclusion, this result suggests that cage rearing system and backyard raising system will play an important role in improving egg production as functional foods.
The objective of this study was undertaken to investigate changes in fatty acid profile of breast and thigh muscle of old laying hens as transferred from cage to backyard raising system and to provide basic information on using old laying hens to producers for environmental managements. Overall, percentages of unsaturated fatty acid obtained from breast and thigh muscle with cage and backyard raising system are the most abundant, followed by saturated fatty acid. For breast muscle, there were no differences (P>0.05) between cage rearing system and backyard raising system in saturated fatty acid (SFA) and mono unsaturated fatty acid (MUFA). Poly unsaturated fatty acid (PUFA) and PUFA:SFA ratios were significantly higher in backyard raising systems in comparison with cage rearing systems (P<0.05). No differences (P>0.05) were detected between both rearing systems for MUFA, PUFA, and PUFA:SFA ratios with thigh muscles. SFA in thigh muscle was significantly (P<0.05) higher in cage rearing systems compared with backyard raising systems. In conclusion, using breast and thigh muscle meats from old laying hens as functional foods or investigating impact assessment on the improvement of farm management system may serve as a good management practice to encourage producers.
The purpose of this study is to understand the architectural space of Chimjeon (寢殿), the King's Bedroom, and Backyard, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for King, living space for King and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of the King's Bedroom in the central area and Backyard in Gyeongbokgung (景福宮), one of the Royal Palace, the result of this study is as followings. Cheonchujeon (千秋殿) and Manchunjeon (萬春殿) were not both sides of Sajeongjeon (思政殿), were on the north side of Gangnyeongjeon (康寧殿) Gangnyeongjeon was not a bedroom for the King and Queen, only for King. Bedroom for Queen was located another space in the Royal palace. There was Hamwonjeon on the west side of Koytaejeon. Jamidang and Cheongyeonroo were on the right side of Koytaejeon The Backyard on the north side of Gyeongbokgung had a wide area for horseback archery and the practice of battle formation The arrangement of the King's bedroom in the central area was assumed like as the Fig 7. and Fig 8.
The circulation and infection of avian influenza virus (AIV) in zoos and backyard flocks has not been systematically investigated. In the present study, we surveyed the birds including those in live bird markets (LBMs) and evaluated co-circulation of AIVs among them. Overall, 26 H9N2 AIVs and one H6N2 AIV were isolated from backyard flocks and LBMs, but no AIVs were isolated from zoo birds. Genetic analysis of the HA and NA genes indicated that most of the H9N2 AIVs showed higher similarities to AIVs circulating in domestic poultry than to those in wild birds, while the H6N2 AIV isolate from an LBM did to AIVs circulating in migratory wild birds. In serological tests, 15% (391/2619) of the collected sera tested positive for AIVs by competitive-ELISA. Among them, 34% (131/391) of the sera tested positive for AIV H9 antigen by HI test, but only one zoo sample was H9 positive. Although AIVs were not isolated from zoo birds, the serological results indicated that infection of AIVs might occur in zoos. It was also confirmed that H9N2 AIVs continue to circulate and evolve between backyard flocks and LBMs. Therefore, continuous surveillance and monitoring of these flocks should be conducted to control further epidemics.

Soluble glass bolus with selenium (Se), copper (Cu) and cobalt (Co) was administered intraruminally to Philippine grazing does fed under backyard farming conditions to determine its effect on blood mineral status. Forty-five does were dosed with SGB intraruminally every 6 months, whereas 15 were without SGB during this experimental period of 10 months. Blood of does in both treatment groups were collected every other month and blood Se, plasma Cu, Ca, P and Mg were determined in this study. All does did not show clinical Se, Cu, Ca, P or Mg deficiency during this experimental period. Selenium concentration of treated does increased (p<0.01) after beginning of this experiment, whereas the level of control does decreased slowly (p<0.01). Two months after SGB administration, all treated does had higher blood Se than the lower limit of $20{\mu}g/l$ suggested by NRC (1981), whereas some control does had lower blood Se concentration than the lower limit of $20{\mu}g/l$. On the other hand, plasma Cu concentration of treated does started to increase more remarkably than control does 4 months after this experiment had started although the difference was insignificant. There were no significant differences between plasma Ca, P or Mg concentration of does in both treatment groups. Soluble glass bolus had no harmful effects on plasma macro mineral concentrations of grazing does. This study showed that SGB was available as mineral supplement to improve imbalances of selected mineral of grazing goats in the traditional backyard conditions in Luzon Island, Philippines.
A stockperson has a significant influence on the productivity and welfare of his animals depending on his stockmanship competence. In this study, stockmanship competence (SC) is defined as the capacity of the stockperson to ensure the welfare of his animals by providing his animals' needs. The study was conducted to evaluate the SC of backyard goat raisers and examine its relationship to goat productivity and economic profitability. There were 101 respondents for this study who have all undertaken farmer livestock school on integrated goat management (FLS-IGM). Interview was conducted in Region I, Philippines on September 3 to 30, 2012 and March 4 to 17, 2013. Data on SC, goat productivity and farmer's income were gathered. Questions regarding SC were formulated based on the Philippine Recommendations for Goat Production and from other scientific literature. Housing, feeding, breeding and health and husbandry management were the indicators used in computing stockmanship competence index score (SCIS). Pearson correlation using Statistical Package for Social Science (SPSS) was carried out to analyse the relationship between SCIS, productivity and income. Based from the results of the study, a majority of the respondents raised native and upgraded goats. The computed mean SCIS before and after undergoing FLS-IGM were 38.52% and 75.81% respectively, a percentage difference of 65.23%. Both index scores resulted in significant differences in productivity and income. The median mature weight and mortality rate of goats before FLS-IGM was 14 kg and 30% respectively. After FLS-IGM, median mature weight was 19 kg and mortality rate decreased from 30% to 11.11%. Likewise, fewer goat diseases were observed by farmers who were able to undergo FLS-IGM. With regard to income, there was a 127.34% difference on the median net income derived by farmers. Result implies that improved SC could lead not only to increased productivity and income of backyard goat raisers but also to better animal welfare.

Many viruses can infect different types of birds, with poultry being the most susceptible. These viral diseases have a direct negative impact on the poultry industry, with significant economic losses. This study examined a group of the most important viruses that infect backyard chickens in 2 specific areas of Basrah Governorate, south of Iraq. The study analyzed avian influenza viruses (AIVs), Newcastle disease virus (NDV), and infectious bronchitis virus (IBV). Two hundred and ninety oropharyngeal swabs, 150 from Abu Al-Khasib and 140 from Shatt Al-Arab regions in the Basrah governorate, were obtained from backyard chickens with clear respiratory signs. The samples were subjected to viral RNA extraction, and the viral nucleic acids were detected using a reverse transcriptase polymerase chain reaction technique. The overall rate of viral infections was 74.8%, which varied depending on the type of virus: 15.8%, 31.3%, and 27.5% for AIV, NDV, and IBV, respectively. The NDV and IBV had much higher infection rates than that of AIV. In addition, the prevalence of AIV in the Shatt Al Arab district was significantly higher than in the Abul Khasib district. Moreover, there were no significant differences between the NDV and the IBV distributions in either of the targeted regions in this study.

This research was conducted to understand the characteristics and traits of Baekje's palace backyard by studying and analyzing the usage, shape, size, material, and place of origin of the odd-shaped stones found at the remains of Baekje's palace in Waggung-ri, Iksan. The results of the research are as following. The odd-shaped stones found at the Baekje palace backyard were used for two purposes. Some of the stones were used as heaping stones(疊石) for the stone waterfall in the backyard while others were used as ornamental stones(置石) to exhibit the uniqueness and beauty of the stone themselves. The stones used for the waterfall had various shapes and materials and were arranged to symbolize the beauty of natural scenery. On the other hand, the ornamental stones were used to exhibit their beauty of forms. Among the twenty six ornamental stones, four were large, four were mid-sized, and eighteen were small. The twenty four heaping stones used for the waterfall were all categorized as small. All of the stones were not too big, easily coming into sight of human beings. The heaping stones were mostly limestones, and some of them were metamorphic rocks such as marble, quartz, green rock, slaty rock, and phyllite. Almost all of the odd-shaped stones used for Baekje's palace backyard have beautiful patterns and specific forms that resemble natural scenes or animals such as a turtle, terrapin, pig, bear, or elephant. Some of the ornamental stones apparently went through carving to emphasize the unique shapes. Considering the usage and characteristic of the odd-shaped stones, one of the most characteristic feature of the Wanggung-ri palace backyard can be said to be 'the garden of odd-shaped stones'. Meanwhile, according to references, interviews, questionings, and on-the-spot surveys on the people who quarried the stones, the stones found at the remains of the Wanggung-ri palace came mostly from Mt. Cheonho in Hosan-ri, Yeosan-myeon, Iksna, and Mt. Shidae in Dosoon-ri, Wanggung-myeon.
