  • A total of 50 individual catfish, the Tra (Pangasius hypophthalmus) cultivated in either floating cages (Tra-c) or in ponds (Tra-p) and the Basa (Pangasius bocourti) raised in three floating cages, were collected in two of the Mekong Delta provinces. The caudal fin of each individual fish was used for protein electrophoresis employing the SDS-PAGE method. The one fillet sides were used as a representative sample to determine the dry matter (DM), crude protein (CP), ether extract (EE) and amino acids (AAs). The catfish oil was extracted from the belly fats, and the fatty acid (FA) composition was analyzed. There were 21 bands of the Tra and the Basa. Protein bands of the two varieties were 28.6-33.3% polymorphic, while polymorphic individuals of the Tra ranged from 80.0 to 100.0%, and the Basa was 90.0% polymorphic. The phenotypic diversity (Ho) of the Tra ranged from 1.71 to 1.80, while the Basa ranged as high as 2.14%. Diversity values (H$_{EP}$) for genetic diversity markers were equal in the Tra and the Basa. The sum of the effective number of alleles (SENA) of both varieties ranged from 3.40 to 3.83 for the Basa and the Tra, respectively. The lower values of Ho and SENA, as compared with those of the fresh water prawn (Macrobrachium equidens) in the area, would suggest that the species with the low values will become extinct due to inbreeding; the gene pools of each observed population were below a suitable threshold. Many of the differences in the nutritional values of the Tra-c, the Tra-p and the Basa were measured; their nutrient values were comparable to fishmeal or fish oil. Most of the DM, CP, and EE were higher in the Tra, especially in the Tra-c. The essential AA content, especially that of lysine, was highest in the Tra-c, next highest in the Tra-p, and lowest in the Basa. Therefore, the amino acid patterns were closer to the ideal patterns in the same sequences. In contrast, the essential FAs were concentrated in the Basa fish oil. It was found that suitable selection of parents for seed production is required to avoid inbreeding. Catfish may be valuable sources of nutrition for both humans and animals, and the differences in their nutritional values by variety and/or management must be taken into account.

  • Sixteen early lactating Nili-Ravi buffaloes, four animals in each group, were used in a Completely Randomized Design to evaluate the effect of varying levels of both ruminally protected fat and urea treated corncobs ensiled with or without corn steep liquor (CSL) on feed intake, digestibility and milk production and its composition. Four experimental diets were formulated. The control (C) diet was balanced to contain 0% fat and 35% urea treated corncobs ensiled with 0% CSL. The low fat (LF), medium fat (MF) and high fat (HF) diets had 45, 55 and 65% urea treated corncobs ensiled with 9% CSL and 2, 4 and 6% ruminally protected fat, respectively. Dry matter, crude protein (CP) and neutral detergent fiber (NDF) intakes by buffaloes remained similar across all treatments. However, DM and NDF as a percent of body weight and digestible DM intakes were higher in HF diet when compared to C, LF and MF diets. Digestible NDF intakes were also significantly higher in HF diet as compared to all other diets. The intakes of ADF and digestible ADF were higher in MF and HF than C and LF diets. The significant variation in digestible DM, ADF and NDF intakes may be attributed to the ammoniation of corncobs along with CSL that caused significant changes in the degradability and digestibility of the diets. Ether extract and digestible EE intakes differed significantly (p<0.05) among all treatments. Intakes of EE were the highest in animals fed HF diet, which was because of added fat. Apparent DM digestibility was the highest in animals C diet and was the lowest in those fed LF diet. Neutral detergent fiber and ADF digestibilities were higher in animals fed diets containing urea treated corncobs ensiled with 9% CSL when compared to those fed diets containing urea treated corncobs ensiled without CSL. Apparent digestibility of CP was noted highest (71.47%) in animals fed HF diet when compared to those fed MF (67.75%), LF (67.04%) and C (65.39%) diets. Milk yield (4% FCM) was the higher in buffaloes fed HF, MF and LF diets than those fed C diet. These results indicated that increasing levels both of fat and urea treated corncobs ensiled with CSL elevated the negative effects of poor quality fibrous feed on milk production by buffaloes.

  • The aim of this study was to evaluate the effects of Sedum sarmentosum Bunge (SS) on the collagen content of the connective tissues in ovariectomized rats. From day 2 until day 37 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with SS at 50 mg/kg BW/day (OVX-SS50), 100 mg/kg bw/day (OVX-SS100) and 200 mg/kg bw/day (OVX-SS200), and an ethyl ether fraction of SS at 10 mg/kg bw/day (OVX-EE) and an ethyl acetate fraction of SS at 10 mg/kg bw/day (OVX-EA). The SS ethanol extracts and SS fractions were orally administrated 1 mL per day. The OVX rats were significantly heavier than the sham-operated rats at all time points, but supplementation with the SS extracts tended to gain weight less than OVX-control. Supplementation with the SS extracts prevented a decrease in the collagen level in bone and cartilage tissues. These results are consistent with the conclusions based on the estrogenic activities of SS. Therefore, it may be used to possibly improve the quality of life in menopausal women.

  • Objective: A 28-d trial was conducted to evaluate the effect of diets with different energy and lipase levels on performance, nutrient digestibility, serum profiles, gut health, and carcass quality in broilers. Methods: A total of 720 one-day-old male Ross 308 broilers ($45.4{\pm}0.5g$) were randomly assigned to one of the following four treatments: i) RET, reduced energy treatment (metabolizable energy = 2,950 and 3,100 kcal/kg for starter and finisher diet), ii) BDT, basal diet treatment (metabolizable energy = 3,050 and 3,200 kcal/kg for starter and finisher diet, iii) RET015, RET+0.15 g/kg lipase, and iv) RET03, RET+0.3 g/kg lipase. There were 10 replications (cages) per treatment with 18 birds per cage. Results: During d 1 to 14, broilers fed BDT, RET015, and RET03 diets had higher (p<0.05) body weight gain than those fed RET diet. During d 1 to 14, 15 to 28 and the overall experiment, feed conversion ratio in RET03 treatment was lower (p<0.05) compared with RET treatment. On d 14, the apparent total tract digestibility (ATTD) of dry matter (DM), ether extract (EE), and gross energy in RET03 treatment was higher (p<0.05) than those in RET treatment, while the ATTD of N was increased (p<0.05) by RET03 treatment. On d 28, broilers fed RET03 diet had higher (p<0.05) ATTD of DM than those fed RET and RET015 diets, while the ATTD of EE in BDT and RET03 treatments was increased (p<0.05) compared with RET and RET015 treatments. Broilers fed RET03 diet had higher villus height (VH) and VH:crypt depth (CD) ratio than those fed RET and BDT diets. The activity of pancreatic lipase in BDT and RET03 treatments was higher (p<0.05) than that in RET treatment. Conclusion: Taken together, lipase supplementation (3,000 U/kg feed) increased growth performance, nutrient digestibility, VH, VH:CD ratio and lipase activity, but decreased triglyceride, low-density lipoprotein cholesterol and the abdominal fat percentage in broilers fed reduced energy diet.

  • Corydalis Tuber has traditionally been used for the treatment of water retention in the body. Administration of the aqueous extract of Corydalis Tuber has been known to be effective for the control of pain and treatment of arthritis. It was reported that Corydalis Tuber possesses anti-inflammatory activity and modulates the intestinal immune system. The effect of Corydalis Tuber against LPS-stimulated expressions of COX-2, iNOS, and $IL-1{\beta}$ in cells of the murine RAW 264.7 macrophages was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription-polymerase chain reaction (RT-PCR), $PGE_2$ immunoassay, and NO detection. The aqueous extract of Corydalis Tuber was shown to suppress $PGE_2$ production by inhibition on the LPS-stimulated enhancement of COX-2 enzyme activity, $IL-1{\beta}$, and iNOS expression in the RAW 264.7 macrophages. Present results suggest that Corydalis Tuber exerts anti-inflammatory and analgesic effects probably by suppressing of COX-2, iNOS, and $IL-1{\beta}$ expressions, resulting in inhibition of $PGE_2$ synthesis. Corydalis Tuber has anti-inflammatory and analgesic effects probably by suppressing of COX-2, iNOS, and $IL-1{\beta}$ mRNA expressions, resulting in inhibition of $PGE_2$ and NO synthesis.

  • Objective: In this study, the effects of Liriope Platyphylla against LPS-induced inflammation was investigated. Methods: Cell viability was determined using the MTT assay. To identify expressions of COX-2 and iNOS mRNA, RT-PCR was performed. Assessment of PGE2 synthesis was performed using the PGE2 immunoassay. Measurement of NO synthesis was performed using the NO detection. Result : The MTT assay revealed that Liriope Platyphylla exerted no significant cytotoxicity in the microglial BV2 cells. RT-PCR analysis revealed that the mRNA levels of COX-2 and iNOS were significantly decreased in the LPS- and 5 mg/ml Liriope Platyphylla treated group. From the PGE2 immunoassay and NO detection, PGE2 and NO synthesis was significantly suppressed in the LPS- and 5 mg/ml Liriope Platyphylla treated group. Conclusion : In these study, Liriope Platyphylla was shown to suppress PGE2 and NO production by inhibiting LPS-stimulated enhancement of COX-2 enzyme activity and iNOS expression. It is very possible that Liriope Platyphylla can offer a valuable mode of therapy for the treatment of brain inflammatory diseases.
