  • 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.

  • This study was conducted to investigate the effects of probiotic mixture on fecal ammonia, caecal microorganism, immune response, egg quality and production in layer under heat stress (HS).A total of four hundred 50 week olds Hy-Line Brown layers were randomly divided into four groups of 100 heads each: C (control, room temperature $25^{\circ}C$), HS (heat stress $33^{\circ}C$), PM (HS plus probiotic mixture 500, 750 mg/kg of diets). Egg production, egg quality, spleen weight, blood IgG and lymphocyte concentrations were increased in the PM group compared to the HS group, while mortality, the heterophil:lymphocyte (H:L) ratio, and corticosterone levelswere significantly decreased. Lactobacillus was increased in the PM group compared to the HS group, but E. coli, coliform bacteria and aerobic bacteria were significantly reduced. Fecal ammonia production was significantly increased in the HS group compared to the PM group. In conclusion, the results of this study that these mixed probiotics can reduce the heat damage of the summer laying hens and can be an effective nutritional strategy to reduce odor generation from feces, and to improve egg quality and laying production through immune response and caecal microbial balance.

  • The objective of the present study was to evaluate effects of probiotic mixture (PM) including Bacillus subtillus, Streptomyces galilaeus and Sphingobacteriaceae on egg production, egg quality, and eliminating odor in laying hens. A total of 240 Hy-Line Brown laying hens (50 wks of age) were divided into four treatment groups (60 replicates of birds, each) in completely randomized design. Groups were assigned to four experimental diets: CON (a basal diet of no PM additive as control), basal diet supplemented with either CP3 (0.3% commercial probiotics), PM3 (0.3% PM), or PM5 (0.5% PM 0.5). Data of egg production and egg quality were obtained during 6 weeks of experimental period. Egg production, Haugh unit, shell thickness, breaking strength, yolk color, and albumin high were significantly increased in CP3 and PM3 compared to those in CON and CP3. Ammonia levels and numbers of E. coli, total aerobic bacteria, Coliform, and Salmonella in feces were significantly increased in order of CON>CP3>PM3>PM5. The present study indicates that addition of 0.3% probiotic mixture including B. subtillus, S. galilaeus and Sphingobacteriaceae to diets may improve egg production, egg quality, and eliminate fecal ammonia of laying hens.

  • Bovine mastitis is an important disease causing serious economic loss in dairy production and food poison in public health. The major causative agents of bovine mastitis include Escherichia coli (E. coli), Streptococcus agalactiae (S. agalactiae), Staphylococcus aureus (S. aureus). These bacteria were found in milk and environmental condition such as feces, water, soil and so on. Recently, many cases of mastitis are derived from environmental contamination of micro-organisms, which important factors for the spread of this disease in farm. Ultraviolet irradiation (UV) has been used as disinfection for waste and water in clinical and industrial facilities. Moreover the UV irradiation has been used as useful bactericidal agents to remove bacterial biofilms in environmental condition. In this study, we determined the bacterial replication in different percentage of water content (PWC) in sterilized saw dust and feces complexes from farm, and results showed that slightly decreased growth pattern of E. coli and S. agalactiae but increased growth pattern of S. aureus in various PWC (200, 400 and 600%) until 144 h incubation. In the bacteriocidal effect of UV irradiation to bacteria in saw dust and feces complex, the results showed that bacteriocidal effect was depended on the UV irradiation time, irradiation distance and PWC. Especially the antibacterial activity of UV irratiation is stronger in low PWC (50%), long time irradiation (50 sec), and short distance (5 cm) than other condition of this study. Furthermore UV irradiation with stirring showed increased the bactericidal effect compared without stirring. These results suggested that bovine mastitis causing agents may survive long time in environmental condition especially saw dust and feces complexes in farm and can cause a various disease including mastitis. Moreover, these data can be used as basis for application and development of UV disinfection to control of bovine mastitis from environmental contaminated bacteria in dairy farm.

  • Previous experiments have shown that aqueous sodium silicate ingested in drinking water may modify the gastrointestinal uptake and(or) tissue retention of certain trace elements, including heavy metals. The present experiment tested, with a mineral balance trial using sheep, the hypothesis that dietary silicic acid could modify uptake, retention and(or) biological effects of dietary Cd. Twenty-four wethers were fed a fibrous diet of ground alfalfa hay and cottonseed hulls to which either 0 or 150 ppm Cd was added as $CdCl_2$ and 0, .5 or 1% silicic acid (as dry matter of the diet). Body weight, feed intake, excretion of urine (volume) and feces (weight), digestibility of dry and organic matter, retention of nitrogen, and packed cell volumes of blood were not affected by either Cd or silicic acid (P<.10). Cadmium decreased (P<.05) Ca retention and increased (P<.01) Mg retention. Silicic acid decreased (P<.05) K retention. Silicic acid failed (P<.01) to modify the retention of added dietary Cd. Body retention of K, Mn and Ni in response to silicic acid varied with Cd levels. If Cd is interfering with mineral retention, silicic acid may be effective in preventing this interference.

  • Three goats were fed with $^{15}N$-labelled rice straw to study the characteristics of digestion, assimilation, metabolism and excretion of C and N compounds from rice straw. It was shown that the amount of $^{15}N$ assimilated into the bodies of the two slaughtered goats accounted for 38.5 and 23.6% of the total amount of $^{15}N$ ingestion in the experimental diet by each goat. The $^{15}N$ excreted via the feces and urine for the three goats accounted for 34.8, 33.2 and 33.9% of the total amount of $^{15}N$ ingested in the feed of the 3 goats. The recoveries of $^{15}N$ from the two slaughtered goats were 73.3 and 57.5%, with the corresponding rates of $^{15}N$ loss 26.7 and 42.5% respectively. The amino acids digestibilities were 68.7 and 54.0%, while the digestibilities of carbohydrates were 74.8 and 67.7% respectively for goats 1 and 3.

  • This study was performed to screen probiotic bifidobacteria for their ability to bind and neutralize lipopolysaccharides (LPS) from Escherichia coli and to verify the relationship between LPS-binding ability, cell surface hydrophobicity (CSH), and inhibition of LPS-induced interleukin-8 (IL-8) secretion by HT-29 cells of the various bifidobacterial strains. Ninety bifidobacteria isolates from human feces were assessed for their ability to bind fluorescein isothiocyanate (FITC)-labeled LPS from E. coli. Isolates showing 30-60% binding were designated LPS-high binding (LPS-H) and those with less than 15% binding were designated LPS-low binding (LPS-L). The CSH, autoaggregation (AA), and inhibition of LPS-induced IL-8 release from HT-29 cells of the LPS-H and LPS-L groups were evaluated. Five bifidobacteria strains showed high levels of LPS binding, CSH, AA, and inhibition of IL-8 release. However, statistically significant correlations between LPS binding, CSH, AA, and reduction of IL-8 release were not found. Although we could isolate bifidobacteria with high LPS-binding ability, CSH, AA, and inhibition of IL-8 release, each characteristic should be considered as strain dependent. Bifidobacteria with high LPS binding and inhibition of IL-8 release may be good agents for preventing inflammation by neutralizing Gram-negative endotoxins and improving intestinal health.

  • The purpose of this study is the improvement of the senior patients' life quality by providing aesthetic and emotional stability by creating and providing a newly designed patient wear for them. Empirical research and analysis were done for the research. Survey from advanced research and clothing design for the senior citizens in Japan and German are analyzed. The result of this research extracted characteristics, which applied to the production of a severe senior patient wear. And the following characteristics emerged: affordability, comfort, aesthetics, and ease of putting on the clothes. To meet these conditions by the details of the clothing design, using fasteners like zippers and Velcro is useful. It is able to solve the problem of affordability making the vertically integrated overalls to be able being separated by zippers in order to reduce the volume of laundry. It was able to overcome the discomfort due to contamination of the feces through the use of the fasteners even though the importance of choosing the comfort material related closely to the comfort. Using material mixed with multiple colors, plaid or bright pink, instead of using neutral colors fulfilled the aesthetic requirement. In Particular, utilizing detachable function fasteners contributed great services.

  • The present study was conducted to evaluate effect of fermented chub mackerel extract (FCME) on lipid metabolism of rats fed a diet supplemented with 1% cholesterol. Four week-old male rats were divided into three groups of 15 rats with 0, 0.1% or 0.2% FCME supplementation. In comparison with control, rats fed 0.2% FCME showed reduction of activities of acetyl-Coenzyme A carboxylase (p<0.05), 3-hydroxy-3-methyl glutaryl Coenzyme A reductase (p<0.01) and fatty acid synthetase (p<0.01). Rats fed 0.2% FCME also showed reductions in free cholesterol in the liver (p<0.05), and in concentrations of free cholesterol (p<0.05), LDL+VLDL-cholesterol (p<0.05), triglyceride (p<0.01) and phospholipid (p<0.01) in the plasma. Plasma HDL-cholesterol concentration was significantly (p<0.05) higher in treatment groups as compared with control group. Atherogenic index was also significantly lower in rats fed 0.1% or fed 0.2% supplement diet, whereas bile acid in feces was not significantly affected. The current study showed that 0.2% inclusion level of the fermented chub mackerel extracts might have hypolipidemic properties.

  • A research study was undertaken to quantify fascioliasis in both live and slaughtered zebu cattle at Savar, Bangladesh. Eggs of Fasciola gigantica per gram of feces (EPG) was determined in a total of 213 fasciola infested live cattle. The EPG per animal ranged from 100 to 400 (mean $138.03{\pm}4.27SE$). Counting of F. gigantica was made in a total of 63 fasciola infested livers of slaughtered cattle. Number of immature flukes per liver ranged from 0 to 37 (mean $8.74{\pm}0.85SE$) and mature flukes ranged from 2 to 121 (mean $20.54{\pm}2.23SE$). Total load of flukes recovered per liver varied from 4 to 132 (mean $29.28{\pm}2.42SE$). Significantly higher EPG (p < 0.05) and higher load of flukes in the livers (p < 0.01) were observed from September to December (post monsoon and winter). The EPG and fluke counts were found significantly higher (p < 0.01) in animals after one year of age and these were also higher in female animals (p < 0.05) than the males.
