Relationship between total transit time and faecal quality in adult dogs differing in body size     

Hernot DC  Biourge VC  Martin LJ  Dumon HJ  Nguyen PG 《Journal of animal physiology and animal nutrition》2005,89(3-6):189-193

Fed the same diet, large and giant-breed dogs have higher faecal moisture and increased frequency of soft stools than small ones. This could be the result of physiological differences, such as a different gastrointestinal transit time. In this study, we have correlated mean total transit time (MTT) with body size and faecal consistency in dogs varying in body size. Fifty dogs from 13 different breeds were used, from a Dachshund to a Great Dane. The MTT was determined using coloured plastic beads [Cummings and Wiggins, Gut, Vol. 17 (1976), p. 219], and faecal consistency was scored daily during the study. We confirmed the strong correlation between height at the shoulder (body size) and faecal score (r = 0.76; p < 0.0001). The MTT increased with body size, from 22 h for a Miniature Poodle to 59 h for a Giant Schnauzer. We found significant positive correlations (p < 0.0001) between MTT and body size as well as faecal scores (r = 0.71 and 0.70 respectively). In the present study, we observed an effect of body size on MTT. In our 50 healthy dogs a longer MTT was related to a poorer faecal quality. Previous studies reported no relationship between body size and the upper gastrointestinal transit time in healthy dogs. So, we hypothesized that body size would mainly affect colonic transit time and that a longer colonic residence time would be related to a poorer faecal quality by promoting fermentation activity.  相似文献   

Les vitamines du groupe B dans les aliments végétaux au Sud Vietnam     

Vialard-Goudou  A.  Darrieussecq  J.  Lau  Nguyen Thi 《Plant foods for human nutrition (Dordrecht, Netherlands)》1958,3(1):426-431

Résumé Les recherches sur la teneur en vitamines du groupe B (thiamine, riboflavine, nicotinamide) faites sur 135 végétaux alimentaires du Sud Vietnam, montrent que les plantes riches en thiamine sont rares; ce sont surtout les graines et quelques rares feuilles(Sesbania grandiflora Pers. 0,365 mg% de partie comestible) et fruit (pulpe deTamarindus indica L. 0,374 mg %:Durio Zibethinus Murr. 0,300 mg %).Les bonnes sources de riboflavine sont aussi rares mais ce sont essentiellement les légumes à feuilles vertes dont spécialementIpomoea aquatica Forsk. 0,500 mg % et un champignonVolvaria esculenta Massee 0,350 mg %.Enfin la nicotinamide se trouve en quantité importante dans les plantes alimentaires étudiées et sa répartition est assez variée. Les teneurs les plus élevées se trouvent dans les graines comme:Arachis hypogea L. 12 mg %,Citrullus vulgaris Schrad. 8,450 mg %Sesamum indicum L. 5,970 mg %.

Summary The vitamins of the B group (thiamine, riboflavine, nicotin amide) were analysed in 135 edible plants from South-Vietnam. The plants rich in thiamine are rare; some seeds, rarer leaves(Sesbania grandiflora Pers. 0.365 mg % of the edible part) and fruits (pulp ofTamarus Indica L. 0.374 mg %,Durio Zibethinus Murr 0.3 mg %) were found.The rich sources of riboflavine are equally rare; into the group belong especially green leaves, in particularIpomoea aquatica Forsk, 0.5 mg % and a fungus,Volvaria esculenta Massee 0.35 mg %.Nicotinamide is found in greater quantities in the analysed plants, the allotment being rather great. The greatest amounts have been found in the seeds:Arachis hypogea L. 12 mg %,Citrullus vulgaris Schrad 8.45 mg %Sesamum Indicum L. 5.97 mg %.

Feeding of Spinach or Sweet-potato Leaves and Growth Performance of Growing Pigs Kept on Smallholder Farms in Central Vietnam     

Nguyen LQ  Everts H  Hue HT  Beynen AC 《Tropical animal health and production》2004,36(8):815-822

We investigated whether the addition of either spinach or sweet-potato leaves to the diet of growing pigs, kept in small holdings in Central Vietnam, would improve growth performance. A control diet was formulated and mixed with each of the vegetables to a final concentration of 15% of the total dietary dry matter. The diets were fed to the pigs from 70 to 100 days of age on six different smallholder farms in Central Vietnam. There were three animals per treatment group per farm and biopsies of adipose tissue were analysed for their contents of alpha-linolenic, eicosapentaenoic and docosahexaenoic acids. The diets without and with vegetables contained on average 0.14 and 0.32 g alpha-linolenic acid per MJ metabolizable energy. The relative percentage of alpha-linolenic acid in adipose tissue was raised by the intake of the vegetables. Eicosapentaenoic acid was not detectable in adipose tissue and the level of docosahexaenoic acid was unchanged. There was a significant stimulatory impact of the intake of either spinach or sweet-potato leaves on growth performance of the growing pigs. It is suggested that an adipose tissue content of alpha-linolenic acid less than 1% of total fatty acids does not allow maximum growth in growing pigs.  相似文献   

Prevalence of Salmonella spp. in pigs, chickens and ducks in the Mekong Delta, Vietnam   总被引：1，自引：0，他引：1  

Tran TP  Ly TL  Nguyen TT  Akiba M  Ogasawara N  Shinoda D  Okatani TA  Hayashidani H 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2004,66(8):1011-1014

In order to determine the prevalence of Salmonella spp. in domestic animals in 6 provinces of the Mekong Delta, Vietnam, 1,098 fecal or intestinal content samples from pigs, chickens, and ducks were examined in the period from July to October, 2000. Salmonella spp. were isolated from 78 (7.1%) of the total samples, which included 23 (5.2%) of 439 pigs, 24 (7.9%) of 302 chickens, and 31 (8.7%) of 357 ducks. From those samples, 80 Salmonella strains were isolated and 25 serovars were identified. The predominant serovars were S. Javiana, S. Derby, and S. Weltevreden. S. Javiana and S. Weltevreden were detected together in pigs, chickens, and ducks. These results indicate that the serovars of Salmonella are widely distributed in domestic animals in the Mekong Delta, Vietnam.  相似文献   

Immunohistochemical study of osteopontin in the spinal cords of rats with clip compression injury     

Moon C  Heo S  Ahn M  Kim H  Shin M  Sim KB  Kim HM  Shin T 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2004,66(10):1307-1310

Expression of osteopontin (OPN) was investigated in the spinal cords of rats with clip compression injury. Western blot analysis demonstrated that OPN protein increased significantly in the spinal cord during the early stages after injury. The increased expression of OPN was partially paralleled by that of proliferating cell nuclear antigen (PCNA). Immunohistochemical staining showed that OPN was expressed in proliferating activated microglia/macrophages in core lesions and in some astrocytes at the periphery of lesions. These results indicate that expression of OPN protein increases mainly in activated microglia/macrophages after spinal cord injury, suggesting that OPN is related to cell proliferation during the early stages after injury, probably leading to tissue remodeling.  相似文献   

Insulin resistance and changes in plasma concentration of TNFalpha, IGF1, and NEFA in dogs during weight gain and obesity     

Gayet C  Bailhache E  Dumon H  Martin L  Siliart B  Nguyen P 《Journal of animal physiology and animal nutrition》2004,88(3-4):157-165

Obesity-induced insulin resistance (IR) is a common problem in humans as well as domestic dogs. It is well-known that this syndrome is associated with many modifications but it is still unclear if the changes are alterations or adaptations. The purpose of this study was to develop obesity-induced IR in dogs, through a long-term overfeeding period, and to explore hormonal and metabolic disturbances associated with the development of this syndrome. Dogs were overfed for 7 months. Body weight increased by 43 +/- 5%, and insulin sensitivity decreased by 44 +/- 5%. Plasma insulin-like growth factor 1 (IGF1), tumour necrosis factor alpha (TNFalpha), and non-esterified fatty acids (NEFA) concentrations progressively increased during the overfeeding period (IGF1: 111 +/- 13 to 266 +/- 32 ng/ml, p < 0.001; TNFalpha: 5 +/- 5 to 134 +/- 41 pg/ml; NEFA: 0.974 +/- 0.094 to 1.590 +/- 0.127 mmol/l, p < 0.05). These metabolic and hormonal impairments are associated with IR, in obese dogs, and could explain, at least in part, the outbreak of this syndrome.  相似文献   

A longitudinal study to identify constraints to dairy cattle health and production in rural smallholder communities in Northern Vietnam     

Suzuki K  Kanameda M  Inui K  Ogawa T  Nguyen VK  Dang TT  Pfeiffer DU 《Research in veterinary science》2006,81(2):177-184

The objective of the study was to investigate constraints to dairy cattle health and production in rural smallholder communities in northern Vietnam, one of the target areas of the Vietnam government's dairy development programme. A total of 99 dairy farms (11 per commune) were recruited from 9 of 32 communes in Ba Vi District, using random two-stage cluster sampling. After the initial questionnaire interviews were conducted, farms were visited at three monthly intervals over a period of 1 year. Information on several health and production parameters relating to the study cattle was collected. Using multiple indicator modelling, it was found that Fasciola infestation, farmers who had been involved in dairying for longer (not indicative of better management skills), larger herd size, and cattle being kept in a shed were linked to reduced reproductive performances.  相似文献   

Changes in allergenicity and digestibility of squid tropomyosin during the Maillard reaction with ribose     

Nakamura A  Sasaki F  Watanabe K  Ojima T  Ahn DH  Saeki H 《Journal of agricultural and food chemistry》2006,54(25):9529-9534

The effect of the Maillard reaction on the allergenicity of squid tropomyosin (TM) was investigated. When TM was reacted with ribose (TM-ribose), its human-specific IgE-binding ability decreased markedly and alpha-chymotryptic digestibility of TM was also altered at the early stage of the Maillard reaction. On the other hand, the modification of the lysine residues in TM using 2,4,6-trinitrobenzenesulfonic acid had no effect on the allergenicity and alpha-chymotryptic digestibility of TM. Therefore, the structural change in TM induced by the Maillard reaction would cause the reduction of the allergenicity, rather than the block of lysine residues. Although peptic digestion diminished the specific IgE-binding ability of TM, the reduction of the allergenicity by the Maillard reaction remained after peptic digestion. These results suggest that hypersensitive reaction of TM-ribose in the human body might be lower than that of native TM.  相似文献
