Lysine Requirement of Piglets

Jin, C.F.,Kim, J.H.,Cho, W.T.,Kwon, K.,Han, In K. Asian Australasian Association of Animal Productio 1998 Animal Bioscience Vol.11 No.1

The experiment was conducted with 120 barrows weaned at 21 days of age to estimate their lysine requirement weaned at 21 days of age when other important amino acids were fortified to get optimal ratio to lysine. The treatments were 1.15% (control), 1.25%, 1.35%, 1.45%, 1.55%, 1.65% total lysine in the diet. Based on the growth performance total lysine requirement of 21-day old pigs appears to be 1.45%. The lowest digestibilities of dry matter and crude fat were found in pigs fed 1.15% total lysine diet and the highest were found in pigs fed 1.65% total lysine diet with no significant differences among treatments. Nitrogen digestibility increased as the total lysine level increased up to 1.35% (p < 0.05) and remained relatively constant beyond 1.35%. However, the best nitrogen digestibility was observed in pigs fed 1.45% total dietary lysine. Gross energy, crude ash and phosphorus digestibilities did not differ due to the increase in total lysine level. The amounts of excreted dry matter and nitrogen differed significantly by the increase in lysine level up to 1.35% (p < 0.05), while phosphorus excretion was not influenced by the lysine level. Dry matter and nitrogen excretion were reduced by 13.6% and 18.4%, respectively, when 1.45% lysine was offered to the pigs compared to the those fed on 1.15% lysine diet. The amino acid digestibilities increased as the total lysine level increased up to 1.45% (p < 0.05), and remained constant beyond 1.45%. The lysine requirement for the pigs weighing 6 to 14 kg seems to be higher than the previous estimates and in order to reduce pollutant excretion the accurate nutrient requirement should be set and applied to the animal.

Fracture toughness and surface morphology of polysulfone-modified epoxy resin

Jin, H.,Yang, B.,Jin, F.L.,Park, S.J. Korean Society of Industrial and Engineering Chemi 2015 Journal of industrial and engineering chemistry Vol.25 No.-

The thermal stability, fracture toughness, flexural strength, and surface morphology of a polysulfone (PSF)-modified epoxy resin were investigated using several techniques. The thermal stability of the PSF-modified epoxy resin was similar to that of the neat epoxy resin. The flexural strength of the epoxy resin decreased with the addition of the PSF. The fracture toughness of the PSF-modified epoxy resin significantly improved compared to that of the neat epoxy resin. The SEM micrograph of the modified epoxy resin showed a relatively rough surface with shear deformation and tortuous cracks, thereby inducing higher fracture toughness in the PSF-modified epoxy system.

<▼1><P>A highly fluorescent, non-perturbing, pentacyclic adenine analog was designed, synthesized, incorporated into DNA and photophysical evaluated.</P></▼1><▼2><P>Emissive base analogs are powerful tools for probing nucleic acids at the molecular level. Herein we describe the development and thorough characterization of pentacyclic adenine (pA), a versatile base analog with exceptional fluorescence properties. When incorporated into DNA, pA pairs selectively with thymine without perturbing the B-form structure and is among the brightest nucleobase analogs reported so far. Together with the recently established base analog acceptor qA<SUB>nitro</SUB>, pA allows accurate distance and orientation determination <I>via</I> Förster resonance energy transfer (FRET) measurements. The high brightness at emission wavelengths above 400 nm also makes it suitable for fluorescence microscopy, as demonstrated by imaging of single liposomal constructs coated with cholesterol-anchored pA–dsDNA, using total internal reflection fluorescence microscopy. Finally, pA is also highly promising for two-photon excitation at 780 nm, with a brightness (5.3 GM) that is unprecedented for a base analog.</P></▼2>

Effects of Supplemental Synthetic Amino Acids to the Low Protein Diets on the Performance of Growing Pigs

Jin, C.F.,Kim, J.H.,Han, In K.,Bae, S.H. Asian Australasian Association of Animal Productio 1998 Animal Bioscience Vol.11 No.1

A total of 120 pigs $(L\;{\times}\;LW\;{\times}\;D)$ averaged 14.16 kg of body weight were reared under six dietary treatments to evaluate the effects of amino acid supplementation on their performances. Treatments were 1) 18% CP diet (control); 2) 15% CP+0.28% Lys (B, 15L); 3) B+0.06% Met (15LM); 4) B+0.13% Thr (15LT) ; 5) B+0.06% Met+0.13% Thr (15LMT); 6) B+0.06% Met+0.13% Thr+0.05% Trp (15LMTT). Each treatment had 4 replicates with 5 pigs per replicate. The daily weight gains were statistically similar in 15LMT, 15LMTT and control groups. Threonine and methionine supplementation resulted in improved growth performance and nutrient digestibilities, while tryptophan supplementation had little beneficial effect. However, the best feed conversion was found in the control group. Dry. matter and CP digestibilities were improved in the 15LMT and 15LMTT groups. Gross energy, crude fat and phosphorus digestibilities were not affected by the treatment. Among the 15% CP groups, nitrogen digestibility showed the tendency to be increased as the more synthetic amino acids were added. Dry matter and nitrogen excretions were significantly reduced by feeding low protein, amino acid fortified diets, while phosphorus excretion was not influenced. Essential amino acids digestibility was higher in 15LT, 15LMT and 15LMTT groups and lower in the control. The 15LT group showed the best lysine digestibility, and methionine digestibilities were higher in all treated groups than control one. Threonine digestibilities higher in 15LT 15LMT, and 15LMTT than the control. The result shows that threonine and methionine should be added to the diet containing 15% CP diet, fortified with lysine to get same performance of 18% CP diet.

Emodin accentuates atrial natriuretic peptide secretion in cardiac atria

Zhou, G.H.,Zhang, F.,Wang, X.N.,Kwon, O.J.,Kang, D.G.,Lee, H.S.,Jin, S.N.,Cho, K.W.,Wen, J.F. North-Holland ; Elsevier Science Ltd 2014 european journal of pharmacology Vol.735 No.-

Emodin, an active anthraquinone constituent isolated from the rhubarb, a traditional Chinese herbal medicine which is widely used in clinical treatment, has cardiovascular protective properties. However, it remains unclear whether the cardiovascular protective actions of emodin are related to an activation of cardiac natriuretic hormone secretion. The purpose of the present study was to explore the effect of emodin on the secretion of ANP, a member of the family of cardiac natriuretic hormones, and its mechanisms involved. Experiments were performed in isolated perfused beating rabbit atria allowing measurement of ANP secretion, atrial pulse pressure, and stroke volume. Emodin increased ANP secretion concomitantly with a decrease in atrial pulse pressure and stroke volume in a concentration-dependent manner. These effects were reversible. Inhibition of K<SUP>+</SUP> channels with tetraethylammonium and glibenclamide attenuated the emodin-induced changes in ANP secretion and atrial dynamics. Furthermore, the emodin-induced changes in ANP secretion and atrial dynamics were attenuated by inhibition of L-type Ca<SUP>2+</SUP> channels with nifedipine. Atropine, methoctramine, tertiapin-Q, and pertussis toxin had no significant effect on the emodin-induced changes in ANP secretion and mechanical dynamics. The present study demonstrates that emodin increases ANP secretion via inhibition of L-type Ca<SUP>2+</SUP> channels through an activation of K<SUP>+</SUP><SUB>ATP</SUB> channel in isolated beating rabbit atria. The results also provide a rationale for the use of emodin in the treatment of impairment of the regulation of the cardiovascular homeostasis.

Effects of Various Carbohydrate Sources on the Growth Performance and Nutrient Utilization in Pigs Weaned at 21 Days of Age

Jin, C.F.,Kim, J.H.,Moon, H.K.,Cho, W.T.,Han, Y.K.,Han, In K. Asian Australasian Association of Animal Productio 1998 Animal Bioscience Vol.11 No.3

A total of 125 pigs (5.8 kg BW, 21 d of age) were allotted in a completely randomized block design experiment. Dietary treatment added carbohydrate sources : corn starch, lactose, glucose, sucrose or dried whey in corn-soybean meal based diet. Each treatment has 5 replicates with 5 pigs per replicate. Lactose, sucrose and dried whey supported a better growth performance than starch and glucose (p < 0.05) during the first and second week postweaning. However, in the third week postweaning no difference was found in ADG and ADFI among treatment. For overall period, pigs fed lactose, sucrose and dried whey diets showed similar growth performance and were superior to starch and glucose. The gross energy digestibility in pigs fed lactose, sucrose and dried whey diets were similar and significantly higher than those fed glucose and starch diets (p < 0.05). DM digestibility was not significantly affected by other carbohydrate sources except starch. Pigs fed lactose, sucrose and dried whey showed the best nitrogen digestibility. In all nutrients digestibility, there was no significant difference among treatment except starch and glucose diet. DM excretion was lower in pigs fed lactose, sucrose and dried whey than pigs fed starch and glucose. In conclusion, it appeared that sucrose could be effectively incorporated in baby pig diet without sacrificing growth performance.

Effects of Various Fat Sources and Lecithin on the Growth Performance and Nutrient Utilization in Pigs Weaned at 21 Days of Age

Jin, C.F.,Kim, J.H.,Han, In K.,Jung, H.J.,Kwon, C.H. Asian Australasian Association of Animal Productio 1998 Animal Bioscience Vol.11 No.2

A total of 125 pigs (5.8 kg of BW) were allotted in a completely randomized block design. Treatments were coconut oil, corn oil, soybean oil, tallow and tallow+lecithin. Each treatment had 5 replicates with 5 pigs per replicate. From d 0 to 7, pigs fed vegetable oil supported greater average daily gain (ADG) and improved feed/gain (F/G) compared to pigs fed the animal fat. Addition of lecithin to tallow increased ADG by 7.2%. Feed intake were similar for all treatment groups. From d 8 to 14, pigs fed coconut oil and soy oil showed better ADG and average daily feed intake (ADFI) than any of the others. From d 15 to 21, pigs fed the tallow diets had lower gains (p < 0.05) than those fed diets that contained vegetable oil and tallow with added lecithin. The effect of different fat sources on gain became smaller with age. Feed intakes were similar between the vegetable oil and lecithin supplemented diets each week postweaning except for pigs fed tallow (p < 0.05). Feed : gain ratios were superior during the initial 2 weeks postweaning period when pigs were provided vegetable oil diet compared with pigs fed tallow. All pig groups had similar feed : gain ratios during 3 weeks. Combinations of tallow with lecithin tended to have intermediate feed/gain ratio. It was found that vegetable oils were much better in improving growth rate of the piglets. Lecithin significantly improved growth rate and feed efficiency of the pigs through the whole experimental period compared to tallow. Coconut oil was the most effective in improving growth of pigs during the first two weeks postweaning. Corn oil had equal value with soy oil in improving growth performance of weaned pigs. When vegetable oil was added, the digestibilities of nutrients except for minerals were higher than when the tallow was fed. Nutrients digestibility was similar among vegetable oils. The addition of lecithin to tallow increased digestibility of gross energy, dry matter, ether extract and crude protein. Crude ash and phosphorus digestibility were not affected by the treatments. Dry matter excretion was not different among treatments except for tallow which showed significantly higher dry matter excretion (p < 0.05), while nitrogen excretion was significantly decreased in pigs fed vegetable oil sources. However, Phosphorus excretion was not affected by the different fat sources.
