  • Objective: The aim of this work was the characterization of the qualitative aspects of meat obtained from Teramana goats, an Italian indigenous breed of the Abruzzo region. Specifically, the study included a comparison with meat samples deriving from Saanen goat kids reared in the same environment and applying the same feeding protocol. Methods: Upon reaching about 7 months of age the animals were slaughtered and samples of muscle tissue were collected to be analyzed. Specifically, meat samples were subjected to evaluations of the physical parameters, including color and the meat ability to retain water, in addition to chemical evaluations that were focused to the determination of the total lipids amount, fatty acids composition, lipid oxidation, and volatile profile. Results: The meat samples obtained from the indigenous breed showed a less intense reddish color and no significant variations for the muscle tissue tendency to retain water, both regarding fresh and cooked meat. Several differences were instead observed in the fatty acid profile. The Teramana samples were richer in saturated fatty acids (p<0.01) and interestingly showed higher concentrations of rumenic acid (p<0.05), a conjugate of linoleic acid that has been associated with important health benefits for the consumers. Another important finding for these meat samples was the marked resistance to oxidative events, as evidenced by the thiobarbituric acid reactive substances-test (p<0.05) and by the characterization of the volatile profile that highlighted a strong reduction in the relative percentage of hexanal (p<0.05), commonly associated to lipid oxidation and the development of unpleasant aromatic notes. Conclusion: The collected data, therefore appeared useful for the valorization of the food product derived from the Teramana goat, although no sensory information has been collected to define the degree of acceptability by the consumers.

  • A study to compare the effects of supplementing Delonix elata, Grewia similis, Tamarindus indica and sunflower seed cake on intake and growth rate of dual-purpose goats fed low quality Buffel grass (Cenchrus ciliaris) hay was carried out. Twenty-eight male goats aged five to seven months (mean weight 12.93${\pm}$3.94 kg) were randomly allocated to four dietary groups in a completely randomised design. The diets were hay plus Grewia similis, hay plus Delonix elata, hay plus Tamarindus indica and hay plus sunflower seed cake. All diets were supplemented with maize bran. The experimental period was 90 days. Voluntary dry matter intake of the supplements was higher for Tamarindus indica (275.5 g/day) and Grewia similis (201.8 g/day) and lowest for sunflower seed cake (81g/day). Goats supplemented with Grewia similis had the highest hay intake (183.8 g/day) while those supplemented with sunflower seed cake had the lowest hay intake (98.9 g/day). Animals fed browse supplements gained significantly more weight (p<0.001) than those with sunflower seed cake. There were no significant differences in live weight change between goats fed the different browses. However, those fed Tamarindus indica gained an average of 20.79 g/d which was slightly higher than the gains for those on Grewia similis and Delonix elata while those fed sunflower seed cake lost weight. Correspondingly, goats supplemented with browse leaf meals had higher feed conversion ratios than those supplemented with sunflower seed cake and required 23.91 to 35.06 g DM of feed to produce one g of weight gain per day. In a separate study, the DM disappearance pattern indicated that Grewia similis and Delonix elata were highly degradable compared to Tamarindus indica. At 24 h of incubation, DM degradability was 627, 588 and 345 g/kg DM for Grewia similis, Delonix elata and Tamarindus indica, respectively. In another study in vivo DM digestibility ranged from 46.1% (for hay alone) to 56.2% (for hay plus Grewia similis). It was concluded that the addition of Tamarindus indica, Grewia similis and Delonix elata leaf meals to Cenchrus ciliaris hay resulted in increased total DM intake, in vivo digestibility and growth rate. Therefore, leaf meals of indigenous browses particularly Tamarindus indica and Grewia similis could be used as supplementary feeds for small ruminants grazing on poor quality roughages during the dry season rather than use of expensive, less effective and intermittently available sunflower seed cake.

  • A survey involving 71 cattle and buffalo farming households under coconut plantations was carried out in three districts (Pannala, Bingiriya and Kuliyapitiya) with the aim of assessing the status of livestock farming. Also, 24 households (eight from each district) were visited monthly for period of one year to collect information on feeding practices. Apart from milk, animals were reared for selling, draught, bio-gas and for manure. Due to difference in system of management of cattle and buffaloes, manure from buffaloes (46%) was more frequently used for coconuts than that from cattle (10%). Majority of cattle were improved breeds (temperate origin) or their crosses, as compared to buffaloes (mainly indigenous). The most predominant management system was tethered grazing during the day, and stall feeding during the night. Coconut land (own or others) and paddy fields were the major grazing areas for the animals. The grass from coconut land was lower in crude protein (8.2%) and digestibility (48%) compared to those from paddy fields (12.1 and 57%, respectively). Of the 288 rations analysed, grass was included in 280 of the daily rations for cattle as compared to 251 for buffaloes. Straw was more commonly included in mixed rations for buffaloes (137 out of 288) than for cattle (53 out of 288). The frequency of use of straw for buffaloes was high in Pannala (75 out of 137 cases). There was wide variation among the improved breeds of cattle and buffaloes in milk production (2 to 9 litres/day), lactation length (6 to 10 months) and calving interval (13-21 months).

  • In two separate experiments with crossbred bulls (Sahiwal $\times$ indigenous) the effect of access to a urea-molasses lickblock (MOL-U-MIN) on straw diets was studied. The animals were given either untreated (US) or urea treated (TS) rice straw with or without lickblock supplementation. In experiment 1, individual dry matter intake (DMI) and dry matter digestibility (DMD) were measured, while in experiment 2 in addition to the above rumen (pH, ammonia, minerals) and blood (protein, minerals and haemotological) parameters were also measured. With both experiments urea treatment did not effect DMI, but lickblock supplementation significantly (p < 0.05) increased DMI. The DMD values obtained in both experiments for TS were significantly (p < 0.05) higher than for US, but lickblock supplementation did not effect the DMD of either US or TS fed animals. Both urea treatment (6.97 vs 6.93) and lickblock supplementation (6.98 vs 6.92) significantly (p < 0.001) reduced the rumen pH. Urea treatment and lickblock supplementation increased the rumcn $NH_3-N$ concentration (mg/100 ml) from 8.7 to 11.9 and 9.2 to 11.4, respectively. Both US and TS diets fed with or without lickblock increased the molar ratio of Na : K in saliva. Phosphorus content in blood plasma was significantly (p < 0.01) increased due to lickblock supplementation, whereas the Fc content in blood was significantly increased (p < 0.01) by urea treatment. Haemoglobin content in blood ranged from 11.3 to 11.7 g/dl, and was not influenced by urea treatment or lickblock supplementation. Lickblock significantly reduced the number of red blood cells, but increased the mean corpuscular volume. It is concluded that feeding urea treated straw with proper mineral supplementation could be a more economical alternative to lickblock supplementation.

  • Jeju Sasa borealis (S. borealis) is indigenous to the Halla Mountain area of Jeju Island, Republic of Korea. However, its dominance has retarded the development of other plant species and lowered biodiversity in this region. The aim of this study was to determine whether S. borealis silage (SS) supplementation affects the chemical composition and antioxidant activity in the fresh meat of Korean native goats (Capra hircus coreanae). The experiment was conducted on 12 Korean native goats at the finisher stage. The feeding groups were the Control (total mixed ration, TMR) and the Treatment (80% TMR + 20% SS). The animals were adapted for two weeks and then subjected to a six-month breeding experiment. Meat samples were excised from the neck, loin, rib, front leg, and hind leg of the slaughtered animals. The meat derived from the treatment group contained more taurine and anserine than that derived from the control group. Both groups did not significantly differ in terms of ω-6/ω-3 fatty acid ratio. The loin and front leg of the treatment group contained significantly higher vitamin E levels than those of the control group. DPPH, ABTS, and FRAP analyses disclosed that the loin and front leg had significantly higher antioxidant activity (p<0.05) than the other parts. Moreover, the loin and front leg cuts of the treatment group had higher antioxidant activity than those of the control group. The present study demonstrated that S. borealis supplementation could effectively improve Korean native goat meat quality.

  • Experiments were conducted to determine the effects of soybean meal (SBM) as a source of protein and sago meal (SM) as a source of carbohydrate on in situ and in vivo digestibility of dietary components in four male goats (Kambing Katjang) and four male sheep (Malin) weighing 25-35 kg. Rumen volume, as well as rumen fluid dilution rate were also determined. The animals were housed in single pens with individual feeding and drinking troughs and each animal was fitted with a rumen fistula. They were fed two diets : chopped rice straw+200 g soybean meal (SBM), and chopped rice straw+190 g soybean meal+300 g sago meal (SBM+SM). Rice straw was offered ad libitum. The supplements were isonitrogenous (80 g crude protein/animal/d), but the proportions of dry matter (DM), organic matter (OM), crude fibre (CF), neutral detergent fibre (NDF) and acid detergent fibre (ADF) were lower in the SBM supplement (191, 165, 11, 40, 15 g/animal/d for DM, OM, CF, NDF and ADF, respectively) than in the SBM+SM supplement (445, 423, 25, 102, 38 g/animal/d for DM, OM, CF, NDF and ADF, respectively). Two animals from each species were fed either supplement in a cross-over design in two periods. Each period lasted for four weeks. In situ and in vivo digestibility studies were carried out, followed by the determination of rumen volume and rumen fluid dilution rate. The results showed that straw DM and total DM intakes of goats (average of $48.7g/kg\;W^{0.75}$, $72.7g/kg\;W^{0.75}$, respectively) were significantly (p<0.01) higher than sheep (average of $3.56g/kg\;W^{0.75}$, $61.6g/kg\;W^{0.75}$, respectively), but OM, N and GE intakes were not significantly different between the two animal species. When the effect of supplements was compared, animals fed SBM+SM supplement had significantly (p<0.001) higher DM, OM and GE intakes than animals fed SBM supplement. Potential degradabilities of rice straw DM were significantly (p<0.01) higher in goats (average of 48.8%) than in sheep (average of 46.1 %). The supplements had no significant effect on the potential degradabilities of DM, OM and NDF, but they had a significant (p<0.05) effect on the degradation rates of DM and NDF. The addition of sago meal in the diet reduced the degradation rates of DM and NDF of rice straw in the rumen. Potential degradability of DM of soybean meal was not significantly different between animal species as well as between supplements. Sago meal was highly degradable. At 24 h of incubation in the rumen, 90-95% of DM loss was observed. There was a significant interaction between animal species and supplements in the in vivo digestibility of ADF and GE. In animals fed SBM supplement, the in vivo digestibility of ADF was significantly (p<0.05) higher in goats ($50.6{\pm}4.22%$) than in sheep ($44.4{\pm}3.21%$), but digestibility of GE was significantly (p<0.05) higher in sheep ($70.2{\pm}1.93%$) than in goats ($63.0{\pm}3.07%$). The digestibility values of CP and OM were significantly (p<0.05) higher in sheep when compared to goats. Animals fed SBM+SM supplement showed significantly (p<0.05) higher DM and OM digestibility values than animals fed SBM supplement, but digestibility values of CP were significantly (p<0.05) higher in animals fed SBM supplement. Differences in in vivo digestibility values of CF and NDF were not significantly different between animal species or supplements. Water intake, rumen volume ($1/kg\;W^{0.75}$), rumen fluid dilution rate and mean retention time were similar between the two animal species. However, rumen fluid dilution rate and mean retention time was significantly (p<0.01) affected by supplements. Animals fed SBM+SM had faster rumen fluid dilution rate and consequently shorter mean retention time.

  • Twelve indigenous(desi) growing male calves of 9-12 months of age($95.3{\pm}12.6kg$) were divided into 4 groups having 3 animals in each group. Each group of calves received 1 kg fresh concentrate mixtures where tea waste was supplemented as 0($T_0$), 50($T_1$), 100($T_2$) and 150($T_3$) g $d^{-1}$ with the replacement of equal amount of concentrate mixtures. In addition, each calf received ad libitum chopped rice straw and 2 kg green grass a day. Dry matter intake increased by offering higher levels of tea waste except in the treatment $T_3$. Daily gain(g $d^{-1}$) was comparatively higher in $T_2$ group(314.6g) compared to other treatments. Feed efficiency(kg DM $kg^{-1}$ gain) was also higher in $T_2$ group(9.9) where feed cost $kg^{-1}$ gain was also comparatively lower(Tk. 25.7) than the other treatments. Dry matter and CP digestibility increased with the increase in supplementation of tea wastes except in the treatment $T_3$.

  • An overview of the epidemiological, biological, and clinical studies of Taenia and taeniasis in Taiwan for the past century is presented. The phenomenal observations that led to the discovery of Taenia asiatica as a new species, which differ from Taenia solium and Taenia saginata, are described. Parasitological surveys of the aborigines in Taiwan revealed a high prevalence of taeniasis, which might be due to the culture of eating raw liver of hunted wild boars. Chemotherapeutic deworming trials involving many patients with taeniasis were discussed. Praziquantel was found to be very effective, but sometimes complete worms could not be recovered from the feces after treatment, probably due to the dissolution of the proglottids. Atabrine, despite some side effects, can still be used, in properly controlled dosages, as the drug of choice for human T. asiatica infection if we need to recover the expelled worms for morphological examinations. Research results on the infection of T. asiatica eggs from Taiwan aborigines in experimental animals were also noted. Since the pig serve as the natural intermediate host of T. asiatica and the predilection site is the liver, a differential comparison of other parasitic pathogens that might cause apparently similar lesions is also presented.

  • For the collection of indigenous prokaryotic species in Korea, 77 strains within the phylum Actinobacteria were isolated from various environmental samples, fermented foods, animals and clinical specimens in 2019. Each strain showed high 16S rRNA gene sequence similarity (>98.8%) and formed a robust phylogenetic clade with actinobacterial species that were already defined and validated with nomenclature. There is no official description of these 77 bacterial species in Korea. The isolates were assigned to 77 species, 31 genera, 18 families, 14 orders and 2 classes of the phylum Actinobacteria. All the strains except one Coriobacteriia strain were affiliated within the class Actinomycetia. Among them, the orders Streptomycetales and Microbacteriales were predominant. A number of strains were isolated from forest soils, riverside soils, and ginseng cultivated soils. Twenty-nine strains were isolated from 'Protected Ecosystem and Scenery Areas'. Morphological properties, basic biochemical characteristics, isolation source and strain IDs are described in the species descriptions.
