In order to investigate experimented effects of Indongdeung Jigolpi-Tang, which is applied to Soyangin, to diabetes, the measurement, comparison and observation made on the contents of volumes of blood glucose, total cholesterol, triglyceride, phospholipid, total protein and electrolyte($K^+$, $Na^+$) in blood serum by giving a high blood glucose, induced by streptozotocin, to hyperglycemic rats, dosing the cooked liquid of I.J.T., and following conclusion was attained. 1. The volume of glucose urine, induced by streptozotocin to hyperglycemic rats, was shown an increase in comparision to a normal flock when $12.50m{\ell}/kg$ of I.J.T. dosed to the rats and checked after two and four weeks and thereby, a sinificant reduction in the volume of blood glucose was made. 2. The volume of total cholesterol of blood serum in the diabetic rats, induced by streptozotocin, was increased in comparision to the normal flock, and in the fouth week of dosing $1.25m{\ell}/kg$ of I.J.T., a significant reduction of total cholesterol volum was shown in the blood serum. 3. The volume of triglyceride in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock, and with dosing $1.25m{\ell}/kg$ and $12.50m{\ell}/kg$ of I.J.T., a significant reduction of triglyceride volium was shwon in the blood serum after second and fourth week. 4. The volume of phospholipid in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing $1.25m{\ell}/kg$ of I.J.T., a significant reduction of phospholipid volium in the blood serum was shown after first and second week. 5. The volume of total protein in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparison to the normal flock however, with dosing the I.J.T., no significant change on the volium of total protein was made in the blood serum. 6. The volume of potassium in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock however, with dosing the I.J.T., no significant change of potassium content was made in the blood serum. 7. The volume of sodium in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing $12.50m{\ell}/kg$ of the I.J.T., a significant increase was shown in the blood serum after first week. Soyangin, accompanying with a middle and upper heat, the I.J.T. - that has a merits of cleaning up fever, solving fever, solving poison, solving thirst and restoring exhaustion - can be proved that it has a blood sugar reduction effect and it is considered that it can be meritorious for strengthening vitality, further, many other exhausting diseases, and can actively used for the cases such as thirst causing disease and a disease that causes an abnormal food hunger, thirst causing and frequent going to pass urine, in particular.

On-farm experiments were carried out in dryland farming in Bali for 48 weeks to study the effect of flock size on the growth and carcass characteristics of cross-bred goat fed gliricidia-supplemented diet. Eighty four bucks with average live weight of 15.87 kg were allocated in a completely randomized block design arrangement, consisted of three treatments and four blocks. The treatments were $3goats/2.7m^2$ (A), $6goats/5.4m^2$ (B) and $12goats/10.8m^2$ (C), while the floor density was the same ($0.9m^2$ per goat). Feed consumed by goat B was similar (p > 0.10), while feed consumed by goat C was lower (p < 0.10) than goat A. Live weight gain of goat B and C were lower (p<0.05) than goat A. FCR of goat B was higher (p < 0.10) than goat A, while FCR of goat C was similar (p > 0.10) with goat A. Goat B has heavier (p < 0.10) head and digestive tract, while goat C has heavier (p<0.10) hindlegs and digestive tract than goat A. Goat B has lighter (p < 0.10) shoulder, while goat C has lighter shoulder and heavier legs (p < 0.10) than goat A. The carcass quality (measured in terms of loin eye muscle area, meat, bone and fat portions) were not affected (p > 0.05) by the flock sizes.

The average twin lambing rate of Bayanbulak sheep is 2% to 3%. However, a flock of sheep with a close genetic relationship and an average of 2 to 3 lambs per birth has been found recently. To determine the major genes controlling the prolificacy of the flock in the present study, the flock was designated A while 100 normal Bayanbulak sheep were randomly selected to comprise the control flock B. Ligase detection reaction method was applied to detect and analyze the 10 mutational loci of the 3 candidate prolificacy genes including bone morphogenetic protein type I receptors, bone morphogenetic protein 15, and growth differentiation factor 9. The 10 mutational loci are as follows: FecB locus of the BMPR-IB gene; $FecX^I$, $FecX^B$, $FecX^L$, $FecX^H$, $FecX^G$, and $FecX^R$ of the BMP15 gene; and G1, G8, and FecTT of the GDF9 gene. Two mutations including BMPR-IB/FecB and GDF9/G1 were found in Bayanbulak sheep. Independence test results of the two flocks demonstrate that the FecB locus has a significant effect on the lambing number of Bayanbulak sheep. However, the mutation frequency of the G1 locus in GDF9 is very low. Independence test results demonstrate that the GDF9 locus does not have a significant impact on the lambing performance of Bayanbulak sheep. Among the 10 detected loci, BMPR-IB/FecB is the major gene that influences the high lambing rate of Bayanbulak sheep.

In this study, image-based flock monitoring and density evaluation were conducted for broiler chicks welfare. Image data were captured by using a mono camera and region of broiler chicks in the image was detected using converting to HSV color model, thresholding, and clustering with filtering. The results show that region detection was performed with 5% relative error and 0.81 IoU on average. The detected region was corrected to the actual region by projection into ground using coordinate transformation between camera and real-world. The flock density of broiler chicks was estimated using the corrected actual region, and it was observed with an average of 80%. The developed algorithm can be applied to the broiler chicks house through enhancing accuracy of region detection and low-cost system configuration.

Turnip yellow mosaic virus (TYMV) is a spherical plant virus that has a single 6.3 kb positive strand RNA as a genome. In this study, RNA1 sequence of Flock house virus (FHV) was inserted into the TYMV genome to test whether TYMV can accommodate and express another viral entity. In the resulting construct, designated TY-FHV, the FHV RNA1 sequence was expressed as a TYMV subgenomic RNA. Northern analysis of the Nicotiana benthamiana leaves agroinfiltrated with the TY-FHV showed that both genomic and subgenomic FHV RNAs were abundantly produced. This indicates that the FHV RNA1 sequence was correctly expressed and translated to produce a functional FHV replicase. Although these FHV RNAs were not encapsidated, the FHV RNA having a TYMV CP sequence at the 3'-end was efficiently encapsidated. When an eGFP gene was inserted into the B2 ORF of the FHV sequence, a fusion protein of B2-eGFP was produced as expected.

Flock House virus (FHV), an insect RNA virus, has a bipartite genome. FHV RNA1 can be packaged in turnip yellow mosaic virus (TYMV) as long as the FHV RNA has a TYMV sequence at the 3'-end. The encapsidated FHV RNA1 has four additional nucleotides at the 5'-end. We investigated whether the recombinant FHV RNA1 could replicate in mammalian cells. To address this issue, we prepared in vitro transcribed FHV RNAs that mimicked the recombinant FHV RNA1, and introduced them into baby hamster kidney (BHK) cells. The result showed that the recombinant FHV RNA1 was capable of replication. An eGFP gene inserted into the frame with B2 gene of the FHV RNA1 was also successfully expressed. We also observed that eGFP expression at the protein level was strong at 28℃ but weak at 30℃. Sequence analysis showed that the 3'-ends of the RNA1 and RNA3 replication products were identical to those of the authentic FHV RNAs. This indicates that FHV replicase correctly recognized an internally-located replication signal. In contrast, the 5'-ends of recombinant FHV RNA1 frequently had deletions, indicating random initiation of (+)-strand synthesis.

A pedigree file of 4,628 records of Muzaffarnagari sheep, maintained at Central Institute for Research on Goats (CIRG), Makhdoom, was used to calculate the inbreeding coefficient of the flock. The flock had been closed for about 25 years (1978 to 2002). The investigation was aimed to study the effects of inbreeding on survivability of lambs. The cumulative survivability of lambs i.e., lambs survived up to 3, 7 and 15 days, 1, 2, 3, 6, 9 and 12 months after birth was considered for the study. The average level of inbreeding of lambs was 1.60%, ranging from 0 to 26.4%. The average inbreeding coefficient of dam over the periods was 1.00% and it ranged from 0 to 25.0%. Significant (p<0.05) adverse effect of lamb's inbreeding was observed on survivability of lambs at all ages except up to 3 and 7 days after birth. On an average, 1% increase in individual inbreeding coefficient should reduce the 0.31, 0.34, 0.32, 0.31, 0.33, 0.44 and 0.49 percent lamb survival up to the age of 15 day and 1, 2, 3, 6, 9 and 12 months, respectively. Ewes inbreeding had non-significant effects on lamb survival at all ages.

The purpose of the survey was to understand the field situation on the occurrence of enteric diseases in poultry farms in Korea. During the period from January of 1991 to December, 1992, 279(35.8%) out of 779 farms surveyed experienced the cases of enteritis in their chickens. The farms with diarrheal problems consisted of 157(45.1%) of 348 broiler flock, 28(32.6%) of 86 breeder flock, and 94(27.2%) of 345 layer flock. The main diseases causing enteritis were frequently appeared as infectious bursal disease(27.3%), colibacillosis(22.6%), and coccidiosis(8.6%). Necrotic enteritis(NE) in chicken occurred in 21 farms(2.7%) among 779 farms examined. The outbreaks of NE were divided 4.7% in breeders, 4.0% in broilers, and 0.9% in layers, respectively. NE occurred mainly in the age(71.4%) of 20~30 days and the mortality was varying from 1.4% to 10.0% for broilers, 3.0% for layers and 0.8% for breeders. Seasonal prevalence of NE showed the highest as 52.4% in summer and followed by 33.3% in autumn, 9.5% in spring and 4.5% in winter.

Although there is circumstantial evidence that infectious bronchitis(IB) in the Korean layer industry has contributed to severe economic losses, the seroprevalence against IB virus(IBV) and risk factors associated with seropositivity are not well known. During May to October 2007, 820 blood samples were randomly collected from 41 laying hen flocks(20 birds in each flock) with $\geq$ 3,000 birds of 18 week of age or older in three provinces of Korea. The samples size was determined considering a flock-size range of 3,000-65,000 birds, an expected bird-level seroprevalence of $\geq$ 15%, and a 95% level of confidence. Serum samples were examined using a hemagglutination inhibition test for antibodies to IBV. The overall apparent flock-level seroprevalence was 46.3%(95% CI, 31.1-66.6) with no statistically significant differences among provinces(X=1.205, p>0.05). There were 19 positive flocks with one to eight seropositive birds, and 11 of these had one or two seropositive birds. None of the measured parameters were significantly associated with seropositivity against IBV in a subsequent multivariable logistic regression analysis. A longitudinal risk factor studies considering management and vaccination characteristics possibly associated with the IBV flock prevalence would be beneficial.
