This study was conducted to evaluate the forage productivity and feed value of Sasa borealis (S. borealis) using growing black goats(S. borealis) in order to improve the utilization of S. borealis and to help mitigate the problem of reduced plant species diversity caused by S. borealis in Hanlla Mountain. One control and three treatments were made by the level of addition of S. borealis silage to the TMR feed. T1(10%), T2(20%), and T3(30%) treatments showed more daily weight gains than control group. Feed conversion ratio of T2 is 4.4g, which is significantly lower than control(P<0.05). The nitrogen retention in the control, which had relatively high dry matter intake, was 12.5g, which was significantly higher than that of T3. Sasa. borealis silage is considered to be able to use as a forage source for black goats, and if it is fed in an appropriate amount, it is considered that it will help improve livestock productivity, such as weight gain and feed conversion ratio.

The experiment was designed on 42 non pregnant Black Bengal goat. Out of which 18 were subjected to a superovulatory treatment comprising of eCG and hCG for embryo transfer study. The remaining 24 goats received no treatment and served as control for parameter studied as well as recipient for embryo transfer studies. Important biochemical constituents such as acid and alkaline phosphatase, total protein and cholesterol and inorganic phosphorus were estimated in the follicular fluid of control and treated group and the values were separately recorded for small medium and large size follicle. The results indicated a significant effect on acid phosphotase activity due to size of follicle. The value increased progressively from small to medium and from medium to large follicles. Alkaline phosphotase activity showed reverse trend. Alkaline phosphotase decreased progressively as size increased. The concentration of inorganic phosphorus did not reveal any significant difference between the control and treatment groups and also between the different size follicles. The concentration of protein decreased significantly from small to medium and from medium to large, although no difference was observed between the control and treatment groups. The concentration of Cholesterol in the follicular fluid indicated a significant increase from small to medium and to large follicle. Here also no difference was observed due to treatment. Similar in the composition of follicular fluid in the respect of above mentioned constituents indicated no of super ovulatory treatment on follicular fluid composition.

This macroscopic observation was performed to investigate the aortic arch and their branches of the Korean native goat. Ten Korean native goats with black hairs ranging in body weight from 15 to 20kg were used. The findings were based on the latex cast of the vessels made by injection of neoprene latex. The results obtained were as follow; 1. The aortic arch of the Korean native goat gave off only one vessel, the Truncus brachiocephalicus. 2. The Truncus brachiocephalicus gave off the A. subclavia sinistra, the A. subclavia dextra and the Truncus bicaroticus. 3. The A. subclavia sinistra gave off the Truncus costocervicalis, the A. cervicalis superficialis and the A. thoracica interna, and continued as the A. axillaris sinistra. 4. The Truncus costocervicalis sinistra arose from the A. subclavia sinistra in all cases and gave off the A. scapularis dorsalis suprema and the A. cervicalis profunda, and continued as the A. vertebralis sinistra. 5. The branching pattern of the A. subclavia dextra was similar to that of the A. subclavia sinistra except the Truncus costocervicalis. The Truncus costocervicalis dextra was arisen together with the A. subclavia dextra in 8 out of 10 cases, while one of the remaining 2 cases arose as the first branch of the A. subclavia dextra and the other was given off directly from the Truncus brachiocephalicus. 6. The Truncus bicaroticus was continued from the Truncus brachiocephalicus after branching off the A. subclavia dextra in 8 out of 10 cases, but the Aa. carotidas communes sinistra and dextra were directly branched from the Truncus brachiocephalicus without forming the Truncus bicaroticus in the remaining 2 cases.

Salmonellosis is one of the life-threating diseases of goat in Bangladesh. Therefore, the present study was designed to study the prevalence of Salmonellosis, and isolation and characterizations of the Salmonella spp. from apparently healthy and diarrheic goat. A total of 47 faces samples were collected from selected place and cultured onto different prescribed medium to isolate it. In this study, 12.76% (6/47) samples were found to be positive for Salmonella spp. During culture on SS agar medium, all of the Salmonella isolates produced round, smooth, opaque, translucent and black color colonies on SS agar media. All of the isolated Salmonella spp. fermented dextrose, maltose and mannitol with production of acid and gas but did not ferment sucrose and lactose. However, these isolates had showed Indole and Voges-Proskauer test negative, Methyl-Red test positive. All of these isolates were subjected to rapid plate agglutination test with polyvalent "O" (Poly 'O') and polyvalent "H" (poly 'H') antisera where positive agglutination were observed. They were highly sensitive to ciprofloxacin, spiramycin and gentamycin; moderately sensitive to oxytetracyline, streptomycin and amoxicillin; less sensitive to sulphamethoxazole and resistant to penicillin-G. Based on the present findings, it may be concluded that the investigated Salmonella spp. from goats might be S. typhimurium, S. enteritidis, S. brandenburg, S. salford, S. newbrunswick, S. newport or S. dublin. Further study will be needed, therefore it requires further characterization using other serological and molecular techniques.

The AT motif-binding factor (ATBF1) not only interacts with protein inhibitor of activated signal transducer and activator of transcription 3 (STAT3) (PIAS3) to suppress STAT3 signaling regulating embryo early development and cell differentiation, but is required for early activation of the pituitary specific transcription factor 1 (Pit1) gene (also known as POU1F1) critically affecting mammalian growth and development. The goal of this study was to detect novel nucleotide variations and haplotypes structure of the ATBF1 gene, as well as to test their associations with growth-related traits in goats. Herein, a total of seven novel single nucleotide polymorphisms (SNPs) (SNP 1-7) within this gene were found in two well-known Chinese native goat breeds. Haplotypes structure analysis demonstrated that there were four haplotypes in Hainan black goat while seventeen haplotypes in Xinong Saanen dairy goat, and both breeds only shared one haplotype (hap1). Association testing revealed that the SNP2, SNP5, SNP6, and SNP7 loci were also found to significantly associate with growth-related traits in goats, respectively. Moreover, one diplotype in Xinong Saanen dairy goats significantly linked to growth related traits. These preliminary findings not only would extend the spectrum of genetic variations of the goat ATBF1 gene, but also would contribute to implementing marker-assisted selection in genetics and breeding in goats.

This study was conducted to evaluate the protein requirement for maintenance of fattening Korean black goat (Capra hircus coreanae). Six male goats with average initial body weight (BW) of $31.78{\pm}4.54kg$ and an average age of 8 months were used in this study. The experiment had a replicated duplicated $3{\times}3$ Latin square design for balancing carryover effects. In the course of the experiment, each of Black goats were fed three diets that were formulated to contain T1 (13%), T2 (16%) and T3 (19%) levels of crude protein (CP). A 14-day diet adjustment period was followed by a 5-day collection period. Dry matter intake (DMI) of groups fed diets with T2 was 966.67g/d which was higher than group fed diets with T1 and T3 were 925.14g/d and 936.08g/d each. Average daily gains (ADG) of black goats were the highest in T2(167.13g/d) But, there was no significant difference. Dietary protein levels affected the apparent digestibility of CP (p<0.05). A significant difference was found in CP intake among treatments and goats receiving T3, T2, and T1 recorded 181.23, 154.57, and 128.78g CP/d, respectively. This was excepted because CP intake is proportional to CP content of diet, which from highest to lowest was as follows: T3 (19%) > T2 (16%) > T1 (13%). Intercept of the regression equation between CP intake and CP balance indicated that maintenance CP requirement was 1.63g/BW0.75.

The goat industry has been developing for many years in Korea to meet demands for food and medicine. However, many complicated patterns of disease have arisen in goat farms as this industry has developed. In this study, disease occurrence patterns in Korean black goats were surveyed in six professional farming households in Imsil and Soonchang in the Jeonbuk province and in Hamyang and Sachon in the Gyeongnam province to understand and extend the goat disease database. We observed morbidity rates between 2.0% and 9.8% for adult goats and between 2.9% and 68.3% for kids. Kids showed a markedly higher incidence of disease when compared to adults. The rate of disease occurrence was 40.0% for floppy kid syndrome (FKS), 37.7% for diarrhea, 16.0% for respiratory disease, and 1.9% for skin disease. The observed mortality rates were 0.7% ~ 10.0%, and 2.2% ~ 24.9% for adult goats and kids, respectively. In addition, FKS, diarrhea, and respiratory disease were observed in 38.3%, 28.9%, and 10.0%, respectively, of dead goats. In conclusion, the majority of diseases in goats occur during the neonatal period, and FKS is the highest single cause of mortality in Korean black goats. Thus careful attention must be paid to kids to reduce the goat mortality rate.

Corynebacterium pseudotuberculosis is the causative agent of caseous lymphadenitis (CLA), a chronic contagious disease in small ruminants. The prevalence of CLA has been reported to be >50% in Korean black goats. CLA is difficult to control due to a lack of efficient vaccines and treatment methods. Effective disinfection of the farm environment may be an alternative strategy for reducing the spread of C. pseudotuberculosis. The objective of this study was to evaluate the efficacy of commercial disinfectants against CLA. The six commercial disinfectants, largely composed of sodium dichloroisocyanurate, sodium hypochlorite, potassium monopersulfate triple salt, quaternary ammonium, citric acid, and copper sulfate, were tested against five different genotypes of C. pseudotuberculosis isolated from goat farms in Korea. Efficacy tests were performed in accordance with the disinfectant efficacy test guidelines recommended by the Animal and Plant Quarantine Agency of Korea with slight modifications. All disinfectants except for copper sulfate exhibited >99.99% killing efficacy under hard water conditions following 30 min of incubation, which is the recommended standard treatment time according to guidelines. The minimum bactericidal treatment time was evaluated by employing treatments for durations of 1, 5, and 15 min. The most effective compounds under hard water conditions were sodium dichloroisocyanurate, potassium monopersulfate triple salt, and sodium hypochlorite, exhibiting >99.99% killing efficacy after 1 min of treatment. In the aqueous solution forms, citric acid and the quaternary ammonium compound were the most effective, but required at least 5 min to kill >99.99% of the bacteria. The current study characterizes the killing efficacy of six commercial disinfectant active compounds against C. pseudotuberculosis. Thus, this study provides essential information regarding the efficacy of the disinfectants used to control CLA in goat farms.

Finding alternative feeds, such as sesame hulls and Prosopis juliflora species can attenuate difficulties of feed shortage and reduce the cost of animal feed in arid and semi-arid countries. Thirty-two Black male kids with similar initial weights (BW = $16.7{\pm}0.80\;kg$) and $120{\pm}5\;d$ of age, were used to evaluate the effect of replacing barley grains and soybean meal with Prosopis juliflora pods (PJP) and sesame hulls (SH) on growth performance, digestibility and carcass and meat characteristics. Kids were equally divided into four dietary treatment groups for an 84-d fattening period. Treatment diets had similar crude protein (CP) and metabolizable energy (ME). The treatment groups were: (T1) no PJP nor SH, (T2) 10% PJP and 20% SH, (T3) 15% PJP and 15% SH, and (T4) 20% PJP and 10% SH. A tendency was detected (p<0.08) for dry matter (DM), crude protein (CP), organic matter (OM) and neutral detergent fiber (NDF) intakes that were greater for T2 than T3 and T4 while T1 was not different from all other treatment groups. Ether extract (EE) intake was the greatest (p<0.05) for T2 and the lowest for T1. Acid detergent fiber (ADF) intake was greater (p<0.05) for T2 than T1 while T3 and T4 were intermediate. Final live weight, average daily gain (ADG) and feed conversion ratio (FCR) were comparable among different treatment groups. Digestibility of DM, OM, CP, NDF and ADF were similar among all treatment groups, however, EE digestibility was the lowest (p<0.05) for T1 when compared to other treatments. In addition, nitrogen intake, nitrogen in urine and retained and retention percentages were similar among all treatment groups. However, N loss in feces was higher (p<0.05) for T2 than T3 and T4 while T1 was intermediate. No differences were observed among treatment groups with respect to fasting live weight, hot and cold carcass weights, dressing-out percentages, mesenteric fat, visceral organs, carcass cuts percentages and carcass linear dimensions. No differences were also observed for dissected loin, leg, rack and shoulder tissues except in the total bone % for loin cuts and in the meat to bone ratio for rack cuts. T3 has the greatest total bone % and the lowest meat to bone ratio when compared to all other treatment groups. No differences were observed between treatment groups in all quality characteristics of the longissimus muscle. The present study demonstrates the potential of using PJP and SH for growing kids without adverse effects on growth performance, carcass characteristics and meat quality.

Ninety pre-puberal (6-7 months) female and 15 pre-puberal male Black Bengal goats were collected on the basis of their phenotypic characteristics from different parts of Bangladesh. Goats were reared under semi-intensive management, in permanent house. The animals were vaccinated against Peste Des Petits Ruminants (PPR), drenched with anthelmentics and deeped in 0.5% Melathion solution. They were allowed to graze 6-7 h along with supplemental concentrate and green forages. Concentrates were supplied either 200-300 g/d (low level feeding) or quantity that supply NRC (1981) recommended nutrient (high level of feeding). Different physiological, productive and reproductive characteristics of the breed were recorded. At noon (temperature=$95^{\circ}F$ and light intensity=60480 LUX) rectal temperature and respiration rate of adult male and female increased from 100.8 to $104.8^{\circ}F$ and 35 to 115 breath/min, indicated a heat stress situation. Young female attain puberty at an average age and weight of 7.2$\pm$0.18 months and 8.89$\pm$0.33 kg respectively. Mean age and weight at 1st kidding were 13.5$\pm$0.49 months and 15.3$\pm$0.44 kg respectively. It required 1.24-1.68 services per conception with an average gestation length of 146 days. At low level of feeding the postpartum estrus interval was 37$\pm$2.6 days, which reduced (p<0.05) with high feeding level to 21$\pm$6.9 days. Kidding interval also reduced (p<0.05) from 192 d at low feeding level to 177 d at high feeding level. On an average there were two kiddings/doe/year. Average litter sizes in the 1st, 2nd, 3rd and 4th parity were 1.29, 1.71, 1.87 and 2.17 respectively. Birth weights of male and female kids were 1.24 and 1.20 kg respectively, which increased (p<0.05) with better feeding. Although kid mortality was affected (p<0.05) by dam's weight at kidding, birth weight of kid, milk yield of dam, parity of kidding, season of birth, but pre-netal dam's nutrition found to be the most important factor. Kid mortality reduced from 35% at low level of feeding to 6.5% at high level of feeding of dam during gestation. Apparently, this was due to high (p<0.05) average daily milk yield (334 vs. 556 g/d) and heavier and stronger kid at birth at high feeding level.
