Atlantic salmon (Salmo salar L.) were fed fishmeal protein for 46 days, and 500 g kg⁻¹ of fishmeal protein substituted with meal from Northern krill (Meganyctiphanes norvegica). No differences were observed in weight gain, length gain, feed conversion or specific growth rate between the groups that could be attributed to dietary manipulation. The adherent microbiota in the hindgut of the two rearing groups were further investigated. By substituting fishmeal with krillmeal, the total viable counts of aerobic and facultative aerobic bacteria colonizing the hindgut of Atlantic salmon increased from 8.5 × 10⁴ to 2.2 × 10⁶. Furthermore, dietary krillmeal affected the adherent hindgut microbiota. The Gram‐positive bacteria Carnobacteria piscicola, Microbacterium oxydans, Microbacterium luteolum and Staphylococcus equorum spp. linens and the Gram‐negatives Psychrobacter spp. and Psychrobacter glacincola were not isolated from hindgut of fish fed the krill diet. On the other hand, Pseudomonas fulgida, Pseudomonas reactans and Stenotrophomonas maltophila were not isolated from the control group fed fishmeal. Acinetobacter lwoffi, which is not normally found in the fish gut, was isolated from both feeding groups. Transmission electron microscopy showed bacteria‐like profiles between the hindgut microvilli in both feeding groups indicating autochthonous microbiota. When fish were fed the krill diet, hindgut enterocytes were replete with numerous irregular vacuoles. These vacuoles were not observed in fish fed the fishmeal protein.  相似文献

Multiple dose pharmacokinetic study of oxolinic acid in cod, Gadus morhua L.     

Ole Bent Samuelsen 《Aquaculture International》2006,14(5):443-450

The plasma, muscle and liver distribution and elimination of the antibacterial agent oxolinic acid were studied after multiple oral (p.o.) administration of 10 or 20 mg kg⁻¹ day⁻¹ to cod (Gadus morhua) for 6 days. The fish, held in seawater at 6 and 12°C and weighing 150–250 g were sampled 24 h following last medication. The concentrations in plasma and tissues were clearly dosage and temperature dependent. The distribution from plasma to muscle (muscle/plasma ratio) was higher than that from a single dose study and independent of temperature and dosage. The distribution from plasma to liver (liver/plasma ratio) was lower than the muscle/plasma ratio and according to this study dependent of the administered dosage but independent of temperature. The elimination of oxolinic acid from plasma, muscle and liver was considerably faster following multiple administration compared to a single administration.  相似文献

Proton nuclear magnetic resonance spectroscopy based investigation on propylene glycol toxicosis in a Holstein cow     

Hanne Christine Bertram  Bent Ole Petersen  Jens ? Duus  Mogens Larsen  Birgitte-Marie L Raun  Niels Bastian Kristensen 《Acta veterinaria Scandinavica》2009,51(1):25

Background

It is unknown which metabolites are responsible for propylene glycol (PG)-induced toxicosis, and a better understanding of the underlying mechanisms explaining incidences of abnormal behaviour of dairy cows fed PG is therefore needed.

Methods

The study included three cows of which one developed PG toxicosis. In order to investigate how the metabolism of PG differed in the cow developing toxicosis, proton nuclear magnetic resonance (NMR) spectroscopy was applied on ruminal fluids and blood plasma samples obtained before and after feeding with PG.

Results

PG toxicosis was characterized by dyspnea and ruminal atony upon intake of concentrate containing PG. The oxygen saturation of arterial blood haemoglobin and the oxygen pressure in arterial blood decreased along with the appearance of the clinical symptoms. NMR revealed differences in plasma and ruminal content of several metabolites between the cow responding abnormally to PG and the two control cows.

Conclusion

It is concluded that PG-toxicosis is likely caused by pulmonary vasoconstriction, but no unusual metabolites directly related to induction of this condition could be detected in the plasma or the ruminal fluid.  相似文献
