  • Subcutaneous abscesses, which occur mainly in goats and sheep, are lymph node abscesses caused by Corynebacterium pseudotuberculosis infection, and are divided into internal, external, and mixed types depending on the type of occurrence. While diagnostic methods for subcutaneous abscesses have been continuously studied, research reports for effective treatment and management of subcutaneous abscesses are inadequate. Therefore, this study was conducted to determine the changes in biometric information related to the inflammatory markers of goats induced by subcutaneous abscesses by infection with C. pseudotuberculosis. For this, hematological tests, analysis of inflammatory indicators, and analysis of serum proteins through electrophoresis separation of goats with healthy goats and goats inoculated with C. pseudotuberculosis to induce subcutaneous abscesses were compared and analyzed by date, and the differences and characteristics were identified periodically. As a result, in goats induced with subcutaneous abscesses, anemia findings related to a rapid decrease in red blood cell (RBC), hematocrit (HCT), and hemoglobin (Hb) were observed, and a significant increase in inflammatory cells expressed in total white blood cell (WBC), neutrophil, and monocytes was observed. And the levels of acute phase protein (APP) such as fibrinogen, haptoglobin, and serum amyloid A (SAA) were observed to increase rapidly immediately after infection. In addition, in the results of electrophoretic analysis of serum proteins, it was observed that the levels of α-globulin and β-globulin were significantly increased in goats with subcutaneous abscesses. That is, when looking at these changes, it was found that the systemic inflammatory response of goats was rapidly induced immediately after infection with the C. pseudotuberculosis pathogen. Through this study, it was possible to identify changes in the biomarkers of goats with subcutaneous abscesses, which had not been reported. Furthermore, these analyzed data are thoughts to be of great help in identifying, treating, and managing the goats of subcutaneous abscesses.

  • To investigate the effects of molasses addition at ensiling on nutritional quality of wilted napier grass, chemical quality and nutrient composition of the silages, digestibility and nitrogen retention at feeding trials were analysed using 4 goats in a cross over design. The results are as follows : 1. Molasses addition at ensiling decreased pH value (3.99) and ammonia nitrogen, and increased lactic acid content by 285% compared to non-additive silage (83.5 g/kg dry matter). 2. There were no differences in digestibilities of dry matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose and cellulose between the silage ensiled with molasses (MS silage) and the silage ensiled without molasses (WS silage). Urinary nitrogen excretion, however, significantly (p<0.05) decreased in goats fed the MS silage, and nitrogen retention was positive in goats fed the MS silages, but negative in goats fed the WS silage. 3. Acetic acid concentration in remained fluids in goats fed the MS silage was lower and propionic and butyric acid concentrations were higher than those in goats fed the WS silage. As water soluble carbohydrate content was higher in the MS silage than in the WS silage, a part of added molasses was still remained in the silage at the feeding trials and could be utilized for energy sources by the goats. Nitrogen may be also effectively utilized in goats fed the MS silage, because the silage were inhibited in proteolysis during ensiling.

  • This trial evaluated the effects of dietary supplementation with monensin sodium on dry matter intake, metabolic parameters and milk yield and milk composition of dairy Saanen goats in the periparturient period. Twelve Saanen pregnant dairy goats were assigned to a treatment and a control group. Saanen goats were fed monensin as its 10% sodium salt in the amount of 33 mg/kg of total dry matter intake during 30 d before parturition till d 42 in milk. Blood samples were collected from each goat at d 30, 15 and 7 before expected kidding time and also in d 1, 7, 13, 19, 21, 28, 35 and 42 postpartum. The serum concentrations of ${\beta}$-Hydroxybutyrate (BHBA), non-esterifed fatty acid (NEFA), calcium, magnesium, inorganic phosphorus, cholesterol, triglyceride, urea, total protein, albumin and glucose and aspartate aminotransferase (AST) activity were determined. The BHBA concentration significantly decreased in goats, which received monensin in comparison to controls in the postpartum period (p = 0.049). The concentration of sodium (Na) was significantly influenced by monensin treatment in the postpartum period (p = 0.048). In addition, the difference in dry matter intake was highly significant between the two groups during the pre-partum period. Controls had more dry matter intake (DMI) than treatment goats (p = 0.0001). Mean 3.5% fat corrected milk production was not influenced by monensin treatment. However, milk fat percentage was significantly decreased in monensin treated goats (p = 0.0017).

  • This experiment was conducted to find out the time to farrowing induction after PGF2$\alpha$ treatment, the rate of farrowing induction, the effect of kids born by the induced farrowing on birth weight and development with study on artificial control of parturition in Korean native goats. A total of 24 pluriparous goats were offered for this experiment. The animals were divided into 4 goats per treatment by administration time(142, 145 or 148 day of pregnancy) and dosage (5 or 7.5mg). The results obtained in this experiments were as follows : 1. The effect of synchronization of estrus was induced 23 goats(95.1%), 16 goats(66.6%) in the 1st treatment and 7 goats(28.5%) in the 2nd treatment PGF2$\alpha$ and exhibited estrus at a mean interval of 75$\pm$5 hours after PGF2$\alpha$ injection. 2. The time to farrowing induction after PGF2$\alpha$ treatment on day 145 or 148 was significantly(P<0.01) shorter than that of the 5mg treatment, but there was no significant difference(P>0.01). 3. Parturition was induced in all goats(100%) treated 5 or 7.5mg of PGF2$\alpha$ on day 148 and 7.5mg of PGF2$\alpha$ on day 145, but was induced 75% in treatment with 5mg of PGF2$\alpha$ on day 145 and 5 or 7.5mg of F2$\alpha$ on day 142. 4. The birth weight and development of kids induced farrowing was heaviest (P<0.01) on days 148 among treatment, but there was no significant difference in dosage.

  • The experiment was divided into two phases. In phase-I fresh embryos were transferred and in Phase-II frozen embryos were transferred. Embryos were collected by using Dulbecco's phosphate buffered saline. In phase-I total of 65 ova were collected out of 107 ovulation in 18 goats. Recovery of ova was 60.74%, of which 51 (78.46%) was fertilized. Sixteen embryos were transferred to 10 recipient goats and kidding was observed in 6 goats, that produced 10 kids. Thus, 62.50% embryo survival and 60% kidding were achieved in phase-I. In phase-II of the experiment, 17 regular cyclic Black Bengal goats were used. The main purpose was to study the viability of caprine embryos after cryopreservation. In this phase the embryos were collected and frozen using Bio-cool freezers. A two step addition of cryoprotectants (5% glycerol and 10% glycerol) and three-step dilution of cryoprotectants with 1mole (M) sucrose was used. Embryos were preserved for 10 to 45 days. Out of 27 embryos preserved, 18 were recovered after freezing and thawing (37$^{\circ}C$ water bath) with 33.33% embryonic loss. Seventeen frozen and thawed embryos were transferred in 9 recipient goats, out of which kidding was observed in 6 goats and 7 kids were produced, giving a 66.66% kidding and embryo survival of 41.17%. The technique utilized for fresh and frozen embryo transfer can be successfully utilized to produce goats of superior genetic merits. The protocol used for addition of cryoprotectant, freezing, thawing and dilution was found suitable for caprine embryo freezing.

  • Chemical composition and nutritive values of napier grass (Pennisetum purpureum Schum.) silages subjected to two cutting intervals were studies; 1st harvest in July (A), and 2nd (B) and 1st (C) harvests in November. Each forage was ensiled with 4% molasses in plastic bags and stored for 5 or 9 months. A feeding experiment with castrated goats was conducted from April to June of the following year. Dry matter (DM) and crude protein (CP) content of the harvests varied from 9.5 to 22.8% and 6.6 to 13.6% of DM, respectively. The dry matter content of the silages fed to the goats were 13.0 to 24.4%, because some effluent was removed from each silage before the feeding trial. The pH values of the silages were between 4.03 and 4.29. Goats were given sufficient silage to meet maintenance nitrogen requirements from napier grass silage. Silage C was not completely consumed, and the silage had low digestibilities of DM, CP, hemicellulose and cellulose. Nitrogen balance was slightly positive for goats consuming silage B and was negative for goats consuming silages A and C. Nitrogen utilization was discussed in terms of ruminal $NH_3-N$ and volatile fatty acid concentration in the rumen fluids. It is concluded that goats could not maintain N-equilibrium not only when a younger forage was consumed at a level of N requirement by a restricted feeding, but also when an older forage could not be consumed enough for N requirement because of feed intake limitation.

  • Twelve Korean native goats, spontaneously infected with mixed species of Eimeria were used to study the possible direct anticoccidial effect of feeding condensed tannin-containing plants on the production of Eimeria oocysts. The effects of feeding pine (Pinus densifora) needles, oak (Quercus acutissima) leaves and lucerne chaff on coccidia oocyst output were studied for a period of 10 days post-feeding. The results indicate that feeding fresh pine needles (40 g condensed tannins (CT) dry matter (DM)/day/goat) and oak leaves (40 g CT DM/day/goat) in combination with lucerne chaff had rapid anticoccidial activities in goats as demonstrated by a sharp decrease in oocyst production. Two days after feeding, the numbers of oocysts per gram of faeces (OPG) from the goats fed pine needles with lucerne chaff, and from goats fed oak leaves reduced by 40% and 44% compared to pre-feeding, respectively. On the sixth day after commencing feeding pine needles and oak leaves, the reduction was 81% and 72%, respectively. Ten days after feeding pine needles and oak leaves, the OPG was reduced by 93% and 85%, respectively compared to pre-feeding. Statistical analysis showed that feeding pine needles and oak leaves to goats naturally infected with coccidia significantly (p<0.001) reduced the numbers of oocysts compared to the control group fed lucerne chaff only. Four clinically important species of coccidia, Eimeria parva, Eimeria ninakohlyakimovae, Eimeria christenseni and Eimeria arloingi were identified in Korean native goats.

  • Objective: This experiment was designed to evaluate the effect of supplementation with soybean or canola oil on milk production and the composition of long chain fatty acids as well as weight changes in the goats and their kids. Methods: Thirty nine mulitparous crossed Alpine${\times}$Nubian goats (initial body weight [BW] $43.5{\pm}1.7kg$) from the day of parturition were assigned to the treatments: grazing control (n = 15); grazing plus 20 mL/goat/d of supplemental soybean oil (n = 12); and grazing plus 20 mL/goat/d of supplemental canola oil (n = 12) from November 26, 2014 to March 7, 2015. The planned contrasts were: CI (control vs supplemented with oils); CII (soybean vs canola oil) to compare the treatment effects. Results: The vegetable oil supplementation reduced weight losses in lactating goats (CI: -0.060 vs 0.090 kg/d; p = 0.03) but did not improve milk production or affect kids' growth. The content of C4, C6, C8, C10, C11, C14, and C18:1n9t in the milk was increased (p<0.05) with respect to control. However, C12, C14, C16, C18, C18:1n9c, C18:2n6c, and C18:3n3 were reduced (p<0.05) in supplemented goats. Conjugated linoleic acid (CLA) was increased (p<0.05) in goats supplemented with oils compared to the control group. Conclusion: Supplementation with 20 mL/d of soybean or canola oil did not affect milk production or kids' performance; however, it increased CLA concentration and reduced the reduced weight losses in lactating goats.

  • The object of this experiment was to investigate the food habits of Korean native goats fed with various roughage sources. The experimental trials were conducted at Unbong Animal Genetic Resources Station in 2008. The experimental roughages include five sources and 25 species in all; grasses and legumes: 5 species (mixed grasses, orchardgrass, tall fescue, alfalfa, white clover), native grasses and weeds: 5 species (mixed native grasses, Miscanthus sinensis Anderss, Arundinella hirta (Thunb.) Tanaka, Barnyard grass, short awn, forage crops and straw: 5 species (barley + hairy vetch, wheat + hairy vetch, rye silage, barley silage, baled rice straw), browse and fallen leaves: 5 species (Mixed browse, Oriental white oak, Quercus serrta Thunb., Oriental cherry fallen leaves, Japanese chestnut fallen leaves), and imported hay and straw: 5 species(timothy hay, tall fescue straw, annual ryegrass straw, klinegrass hay, alfalfa hay). Ten Korean native goats were selected which had nearly the same body weight (average $24{\pm}2.8$ kg). The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period (p<0.05). Among all the 25 species of roughages, the favorite intake species order by Korean native goat was observed like this: Quercus aliena, Querancas serrta Thunb and Mixed browse, which was a lower intake compared to other domestic herbivores. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. On the other hand, compared to each roughage source, total intake amount by Korean native goats was showed as browse and fallen leaves (33.1%) among trials roughage sources. Based on these results, the food habit of Korean native goats seems to be closer to the browser.

  • This study investigated the use of multinutrient blocks (MNB) composed of 35% date syrup, 35% date syrup byproducts, 10% date fronds, 7% urea, 7% cement and 6% common salt for growing small ruminants, as partial substitute for the roughage component of the diet (Rhodes grass hay) and its effect on feedlot performance and economics of feeding. Eight growing local Omani goats and 8 sheep (each about one year old) were used in this study. Mean body weights for goats and sheep (kg), respectively were $21.1{\pm}4.5$ and $25.5{\pm}4.1$. The goats and sheep were subdivided into two sub-groups of more or less equal body weights for each species. Each sub-group in both species was either fed on 0.5 kg concentrate+ad libitum Rhodes grass hay or the same diet+restricted hay (about 0.2 kg/head/day) and ad libitum amount of MNB. Sheep significantly (p<0.05) consumed greater amounts of MNB ($36{\pm}17$g/head/day) than goats ($6{\pm}2.5$ g/head/day). Feeding of the MNB was effective in sparing about 40% of the roughage Rhodes grass hay for goats (from 240 to 140 g) and about 42% for sheep (from 252 to 146 g) or approximately 100 g/head/day for both goats and sheep. This reduction (or sparing) in the consumption of Rhodes grass hay was coupled by an improvement in daily liveweight gain (g/head/day) in both goats (from 29 to 46 by 58.6%) and sheep (from 26 to 39 by 50%) and also by an improvement in the feed conversion efficiency (g feed/g gain) of both goats (from 25 to 13.8 by 45%) and sheep (from 28.7 to 17.2 by 40%). Cost of daily consumed feeds as well as cost/kg gain (or cost of meat) were both reduced due to feeding of MNB. They were both respectively reduced by 7.5% (from 53 Baisa/day to 49) and 38% (from 1,828 Baisa/kg to 1,140). It was economically viable to feed MNBs containing date by-products and urea to small ruminants in the Sultanate of Oman.
