Anti-antibodies against three mouse monoclonal antibodies viz. IIB5D6, VIA6E8 and VIC1F9 (specific to bovine growth hormone) in rabbits have been generated and characterized. Ammonium sulfate fractionated and affinity-purified monoclonal antibodies were used for producing anti-antibodies. The generated anti-antibodies were against common as well as uncommon antigenic determinants present in mouse monoclonal antibodies. The raised anti-antibodies replaced [$I^125$ ]bGH bound to goat liver microsomes indicating production of anti-idiotypic antibodies against bovine growth hormone. These antibodies can have profound implications in vivo in lactating bovines for enhancing milk yield.

Black Bengal goat is primarily reared for meat, skin comes here as a by-product. The present trial describes the effect of age on different carcass characteristics of Black Bengal goats of either sex. A total of 61 Black Bengal goats of different age and sex groups were slaughtered. They were reared under semi-intensive management on milk alone or with concentrates (of 10.14 MJ ME and 10.48 g M/kg DM) and freshly cut Napier grass (2 MJ ME and 25 g CP/kg of fresh matter) that provides the estimated NRC (1981) requirement. The four age groups were: pre-weaned kids (0-90 day), post-weaned kids (91-180 days), growing (181-365 days) and adult (>365 days). Goats were slaughtered according to 'Halal' method by severing the major vessels of the throat by a transverse cut. Different slaughter parameters of Black Bengal goat can be best predicted from the equations as follows: live weight (kg)=0.801 (shoulder height (cm))-24.32, ($r^{2}$=0.94); carcass weight (kg)=0.364 (height at hind legs (cm))-11.54, ($r^{2}$=0.91); edible weight (kg)=0.623 (shoulder height (cm))-19.94, ($r^{2}$=0.91) and saleable weight (kg)=0.701 (shoulder height (cm))-21.99, ($r^{2}$=0.92). Live weight, carcass weight, edible weight and saleable weight of castrated goat at one-year onward ranges from 20-22, 9.4-10.5, 14-16 and 16.6-18.8 kg, respectively, which are about 80% higher than most of the reported observations on Black Bengal goat of same age and sex. Slaughter weight, warm carcass weight, edible weight and saleable weight increased curvilinearly with age of slaughter but not affected (p>0.05) by sex. However, linearity of the response curve of affect of age on mentioned parameters ends at around 9 months. Visceral fat as per cent of live weight increased curvilinearly with age and attain its maximum (about 6%) at about 500 days. However, linear part of the quadratic model ends at about 300 days when visceral fat content is about 4.8% of body weight. Blood and skin yield for one-year old male goat was 797 g and 1.61 kg, respectively. Absolute yield of blood and skin increased curvilinealry and attained maximum level at about 400 days (13.3 months). Average proportion of different carcass cut were - round 27%, rump 7%, loin 10%, ribs (6-12th) 14%, shoulder 21%, Neck 7%, chest 14%. Thigh and shoulder constituted about 48.3% of the cold carcass weight. Overall crude protein content of meat samples of different carcass cuts progressively decreased with age starting from 57 at 0-90 days to 58, 47 and 33 per cent, respectively at 91-180, 181-365 and >365 days, respectively. Overall meat fat content increased almost linearly from 11.1% during 91-180 days to 22.9 and 39.5% during 181-365 and >365days, respectively. Results from this trial suggest that both carcass yield and carcass composition changes with age; and sex have little or no effect on carcass yield and carcass composition. However, caution should be made in using second conclusion as there were few female animals slaughtered relative to the male. Optimum slaughter age for Black Bengal goat reared under semi-intensive management with adequate feeding and management would be about 9 months when their live weight, warm carcass weight, edible and saleable weight of carcass can be about 16.74, 7.28, 12.05 and 13.81 kg, respectively.

Mongolia has 80% livestock of total agriculture industry, 170,000 farms are engaged, 2,500,000 of cows that were beef and dairy cows are raised. Despite of Mongolian has great application with milk, there are not clear differences between cow and dairy cattle, and the production of milk is also low. But the milk suppliers are varied (horse, sheep, goat, etc), so that the total milk production is 500 thousand ton per year. It's really considerable to improve the breed of owing to many problems with big differences among milk qualities. For carrying out for first year project, artificial insemination project was operated with 3rd grade Holstein semen that were imported from S. Korea, and initiation and field training were also carried out through appropriate AI technique we developed for Mongolia environment. Local information research and MOU conclusion were done with professor D. Altangerel in May $10^{th}{\sim}13^{th}$, 2009, and development for AI technique and AI equipments were supplied for Mongolia breeding and natural environment in July $10^{th}{\sim}17^{th}$ in 2009. All cows were treated by synchronization for AI. To do this, $PGF_{2\alpha}$ injection were treated for luteal phase cow, if it wouldn't work, try again after 11 days. After confirmation of estrus, AI and AI training were carried out with sperm injection in the uterus or cervix by rectum-vagina method which is common worldwide, the most effective artificial insemination technique. If cows were return to next estrus cycle, second AI was carried out about approximately 21 days after artificial insemination. After 2 months, all cows not showing return estrus should be taken pregnancy test. Every pregnant cow will be cared thoroughly. Total 48 cows administrated by $PGF_{2\alpha}$ for synchronization and after 48 hours 45 cows (93.8%) showing estrus were detected and then artificial inseminate them within who 8 cows (27.8%) showed return estrus. Therefore, Using $PGF_2{\alpha}$ for synchronization is effective to use for Mongolia breeding conditions. There are possibility of base for food production after all, including increase of livestock production in Mongolia by improvement of breeding cow with AI and embryo transfer project.

This experiment was conducted to investigate the genetic and non-genetic factors affecting kid survivability in goats from birth to 90 days of age. The purebreds had lower survivability than the crossbreds, with significant (p$<$0.05) difference amongst themselves for the age of 31 to 90 days. The locational effect on survivability was insignificant for all the periods except 16 to 60 days (p$<$0.05) of age. The sex and birth type also had significant (p$<$0.05) effect on survivability for all the periods except 0 to 7 days of age. The survivability was found to be significantly (p$<$0.05) higher for kids born in summer season followed by those born in winter and rainy season. Milk produced by the does were significantly (p$<$0.05) affected on the survivability of kids during the period from 16 to 60 days of age. The survivability of kids were highest and lowest having milk yield of doe found to be 400-600 g/day and 80-200 g/day, respectively. Birth weight had significant (p$<$0.05) effect on survivability for all the stages of growth up to 90 days of age. Survivability was positively correlated with does’ milk yield as well as kids birth weight. Interactions of sex with location or birth type were significant (p$<$0.01 and p$<$0.05, respectively) though interaction between sex and genetic group was insignificant.

Rice alcoholic beverages, cheongju and beopju, which are recorded in "Koryodokyung", "Koryosageolyo", and "Koryosa", were used in national and royal ceremonies, and yakju was used in the Palgwanhoi ritual. In the late $11^{th}$century, King Munjong imported hwaju and haenginjabeopju from the royal family of the Song Dynasty. Alcoholic beverages in the early $12^{th}$century included the medical use for kings, such as gyehyangeoju, which the Emperor of the Song Dynasty sent to King Yejong, baekjainju, which was sent to King Myeongjong for his health, and yangju, which is goat milk fermented alcohol from the nomads in the northern regions. In the early$13^{th}$ century there was also dongrak, which is a horse-milk fermented alcohol, grape wine sent from Yuan to King Chungryeol in the late $13^{th}$ century, and sangjonju, a type of special cheongju sent from Yuan in the early $14^{th}$ century. Baekju from Yuan was recorded in oral traditions, which suggests that soju, which is distilled cheongju, was consumed in the late $14^{th}$ century. Gold and silver wares for alcoholic beverages had important political, social, and economic meanings as national gifts to other countries and internally as the king's royal gift to his subjects. In the late $14^{th}$ century, soju was prohibited, and the use of gold and silver wares for alcoholic beverages was banned at the same time. This study examined the historical characteristics of the use of traditional rice alcoholic beverages, the emotional preference for foreign alcoholic beverages, and the gold and silver wares used for alcoholic beverages Koryo Dynasty.

A study was conducted to evaluate the replacement value of Leucaena leucocephala and Gliricidia sepium as nitrogen sources in commercial type supplements for dairy goats. Six crossbred $(Toggenburg{\times}Saanen)$ goats at late stage of lactation were allocated to three dietary treatments in a double $3{\times}3$ Latin square design. The animals were offered rhodes grass (Chloris gayana) hay ad libitum and supplemented with either Leucaena-based concentrate (LBC), Gliricidia-based concentrate (GBC) or commercial based concentrate (CC). Voluntary food intake, milk yield and composition and changes in live weight were measured. The total dry matter (DM) intake was higher (p<0.05) in goats fed GBC than CC (1385 vs 1331 g/d). The DM intake for LBC (1343 g/d) was similar to CC (1331 g/d). The DM intake of hay was also higher (p<0.05) in goats fed GBC (834 g/d) than those receiving LBC or CC (789, 782 g/d, respectively). Animals supplemented with GBC recorded positive (11 g/d) weight gain while the other groups lost weight (13, 19 g/d) for LBC and CC respectively, although these differences were not statistically significant (p>0.05). The composition of milk were: butterfat 58, 49 and 55 g/kg; crude protein 37.0, 35.4 and 36.1 g/kg; lactose 33, 29 and 30 g/kg; Ash 8.5, 8.5 and 7.9 g/kg and total solids 136.5, 121.9 and 129.0 g/kg, for goats fed LBC, GBC and CC respectively. There were no differences in the composition of milk due to these dietary treatments. At the end of performance trial, a digestibility trial was conducted using 6 female goats allocated to the three treatments (LBC, GBC and CC) in an incomplete randomized block design and each goat received a different supplement in each of two successive periods. There were no differences in nutrient digestibility except for DM, which was higher (p<0.05) in CC compared to the other treatments (615, 622, 720 g/kg for LBC, GBC and CC, respectively). Economic analysis showed that CC diet was more expensive (0.20 US$/kg) and had a lower margin over supplementation (0.11 US$) compared to LBC and GBC (0.13 vs 0.12 US$/kg and 01.5 vs 0.12 US$, respectively). It is concluded that the Leucaena and Gliricidia could contribute as nitrogen sources in compounded diet supplements without any detrimental effects on production in dairy goats.

Lactic acid bacteria are microorganisms that are closely associated with human and/or animal environments, and are categorized as generally recognized as safe (GRAS) organisms due to their ubiquitous appearance in foods and their contribution to the healthy microflora of mucosal surfaces. This study was performed to isolate and identify lactic acid bacteria with antagonistic effects against food-borne pathogens. A total of 3,000 acid-producing bacteria were isolated from infant feces, cattle feces, goat feces, dog feces, pig feces, vaginal tracts, vegetables, fruits, Kimchi, Jeotgal, fermented sausages, raw milk, cheese, yogurt, Cheonggukjang, Meju, and Makgeolli cultured on MRS agar with 0.05% bromocresol purple. For the isolation of bacteriocin-producing bacteria, the diameter of the clear zone was measured on MRS agar plates. Twenty-six isolates exhibited strong antibacterial activity against indicator strains such as Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella enterica serovar Enteritidis. Lactic acid bacteria were identified as Enterococcus faecalis, Enterococcus faecium, Enterococcus hirae, Lactobacillus acidophilus, Lactobacillus amylovorus, Lactobacillus curvatus, Lactobacillus plantarum, and Pediococcus acidilactici by 16S rDNA gene sequence analysis. The results of this study suggest that the isolates could be used as potential probiotic starters for functional food applications.
