A 5‐year‐old male Norwegian Forest cat presented with increased hepatic serum biochemical parameters. Abdominal radiography showed an oval cranioventral mass and ultrasound revealed a mobile mass attached to one hepatic lobe. Computed tomography (CT) confirmed that the mass was attached to the right medial liver lobe. Differential diagnoses were an accessory liver lobe, benign neoplasia, and focal nodular hyperplasia. The mass was removed and histopathology confirmed the mass to be normal liver tissue. Accessory liver lobe should be included in the differential diagnosis of a mobile cranial abdominal mass with a similar ultrasonographic or CT appearance to the liver.  相似文献

In this study, we explored the potential utility of the human‐focused FilmArray® Respiratory Panel for the diagnosis of a broad range of influenza viruses of veterinary concern as compared with the standard portfolio of recommended TaqMan®‐based diagnostic tests. In addition, we discuss some potential operational advantages associated with the use of such integrated sample extraction, amplification and analysis devices in the context of a future long‐term, dual‐role strategy for the detection of emergency diseases of both human and veterinary concern.  相似文献

The effect of different combinations of local anaesthesia,sedative and non-steroidal anti-inflammatory drugs on daily growth rates of dairy calves after disbudding     

AJ Bates  RA Laven  F Chapple  DS Weeks 《New Zealand veterinary journal》2016,64(5):282-287

AIM: To assess the effect of sedation and local anaesthesia (LA) at disbudding, and the addition of meloxicam or ketoprofen treatment, on weight gain in dairy calves following disbudding.

METHODS: Friesian-Jersey cross calves, from four dairy farms, were enrolled when 3–6 weeks old. All calves (n=271) were disbudded by veterinary personnel and randomly assigned to six groups: 136 were disbudded without sedation or LA, of which 31 received 20 mg meloxicam S/C and 75 received 150 mg ketoprofen I/M. A further 135 were disbudded with sedation (0.25 mg/kg xylazine I/M) and LA, of which 30 also received meloxicam and 75 received ketoprofen. Calves were weighed 3 days before, and 15 and 30 days after, disbudding (Day 0). Daily weight gain was analysed using mixed models and ANOVA.

RESULTS: Complete results were obtained from 263 calves. From Day ?3 to Day 15, the growth rate of calves disbudded without pain relief (0.53 (95% CI=0.47–0.60) kg/day) was less that of calves disbudded with some form of pain relief (0.65 (95% CI=0.62–0.68) kg/d; p=0.004). There was no difference between the effect of meloxicam or ketoprofen (p=1.00). An interaction between use of sedation and LA and additional non-steroidal anti-inflammatory drugs (NSAID) meant that NSAID treatment did not increase growth rates in calves disbudded with sedation and LA but did increase growth rates for calves disbudded without pain relief (p<0.05). From Day 16 to Day 30 there was no effect of NSAID treatment on growth rate, but calves receiving LA and sedation grew faster (0.74 (95% CI=0.69–0.80) kg/day) than calves disbudded without LA and sedation (0.66 (95% CI=0.61–0.71) kg/day; p=0.018). From Day ?3 to Day 30, calves disbudded with sedation and LA grew faster (0.71 (95%CI=0.64–0.77) kg/day) than calves disbudded without sedation and LA (0.60 (95% CI=0.55–0.65) kg/day; p=0.011). However, addition of NSAID to sedation and LA made no further difference to growth rates (p=0.69).

CONCLUSIONS: Dairy calves disbudded with no pain relief had slower growth rates than calves receiving pain relief. From Day 15 to 30 calves given no pain relief, or NSAID alone, grew more slowly than those receiving sedation and LA at disbudding. The addition of NSAID treatment to sedation and LA did not further increase growth rates.

CLINICAL RELEVANCE: This study adds to the evidence that pain management when disbudding is beneficial for calf productivity as well as calf welfare.  相似文献   

Influence of foetal calf serum supplementation during in vitro embryo culture in Iberian red deer     

María Iniesta‐Cuerda  Irene Snchez‐Ajofrín  Olga García‐lvarez  Alicia Martín‐Maestro  Patricia Peris‐Frau  Jos Antonio Ortiz  María Rocío Fernndez‐Santos  Jos Julin Garde  Ana J. Soler 《Reproduction in domestic animals》2019,54(Z4):69-71

Nowadays, the use of foetal calf serum (FCS) during in vitro embryo culture is very controversial. Whilst some authors have encouraged its use, others reject it because of its harmful effects. Although in vitro embryo production in red deer is a promising assisted reproductive technique, it is still in its infancy and a great effort is needed to update the protocols used. The aim of this study was to assess whether FCS supplementation in red deer embryo culture medium is necessary to produce blastocyst and, if so, when is the best time to add it in terms of blastocyst production and quality. In vitro blastocysts were cultured with FCS added at 24, 48 or 96 hours post‐insemination (hpi). In addition, a treatment without FCS was used as control. Six hundred and ninety‐four cumulus–oocyte complexes were collected for in vitro fertilization. Cleavage rate was examined at 48 hpi, and blastocyst yield was recorded on days 6, 7 and 8. FCS had no influence on cleavage and blastocyst rate for any of the treatments studied. However, the number of cells was higher (p = .025) in those blastocysts cultured with FCS from 48 hpi compared with FCS‐free culture media (93.88 ± 7.76 vs. 54.11 ± 8.36). In conclusion, the addition of FCS to the embryo culture medium at 48 hpi improves the quality of red deer blastocyst, although it does not affect the percentage of embryos obtained.  相似文献   

Effect of supplementation with MgCO₃ and l-Tryptophan on the welfare and on the carcass and meat quality of two halothane pig genotypes (NN and nn)     

N. Panella-Riera  A. Dalmau  E. Fbrega  M. Font i Furnols  M. Gispert  J. Tibau  J. Soler  A. Velarde  M.A. Oliver  M. Gil 《Livestock Science》2008,115(2-3):107-117

Sixty-one animals with different Halothane genes (homozygous halothane positive, n = 34; and homozygous halothane negative, n = 27) were fed with three diets (control group, with no supplement; magnesium (Mg) group with 1.28 g MgCO₃/kg and tryptophan (Trp) group with 5 g l-Trp/kg) during the last 5 days before slaughter. Animals were submitted to minimal stress antemortem conditions. Pig behaviour was recorded at the experimental farm, raceway to the CO₂ stunning system and during the stunning period. Corneal reflexes were recorded after stunning as well. There were no differences in feed intake among diets (P > 0.05) during the 5 days of treatment. The halothane positive (nn) group had lower intake than the halothane negative (NN) group (P < 0.01). The behaviour of the pigs in the raceway did not differ (P > 0.05) among treatments or halothane genotype. A significant (P < 0.001) interaction diet  halothane was found in the time to appear the first retreat attempt during the exposure to the CO₂ system. In the nn group, the time of performing the first retreat attempt was later in the Mg (P < 0.05) than the control group. Moreover, in the Mg group, the nn had a later (P < 0.05) first retreat attempt than the NN. Thus, Mg supplementation could have a positive effect on welfare of nn pigs. The nn had a lower proportion of animals that showed corneal reflexes after stunning than NN, indicating a higher effectiveness of the stunning method in nn pigs. Neither Mg nor Trp affected carcass quality and meat quality parameters, although significant differences were found between genotypes.  相似文献

An epizootic of bovine ephemeral fever in New South Wales in 2008 associated with long-distance dispersal of vectors     

DS Finlaison  AJ Read  PD Kirkland 《Australian veterinary journal》2010,88(8):301-306

Objective To report the rapid transmission of bovine ephemeral fever ( BEF) virus from north-western New South Wales south to the Victorian border in January 2008 and to present data that suggests an uncommon meteorological event caused this rapid southward dispersal of vectors. Procedure The locations of reported clinical cases, data from sentinel herds and results from a survey of cattle in the southern affected area were examined to delineate the distribution of virus transmission. Synoptic weather charts for January 2008 were examined for meteorological conditions that may have favoured movement of vectors in a southerly direction. Results Cases of BEF and exposure to BEF virus in NSW were confirmed west of the Great Dividing Range, extending from the Queensland border to Finley, on the far North Coast and around the Hunter Valley. A low-pressure system moved south across the state on 18–19 January 2008, preceding the first cases of BEF in the south of NSW by 1–2 days. Conclusion Heavy rainfall in December 2007 provided a suitable environment for vector breeding, resulting in the initiation of and support for continuing BEF virus transmission in north-western NSW. The movement of a low-pressure system south across central western NSW in mid-January 2008 after the commencement of BEF virus transmission in the north-west of the state provided a vehicle for rapid southward movement of infected vectors.  相似文献   

The relationship between feed intake behaviour with intramuscular fat, cholesterol and fatty acid composition in pork     

WM Rauw  I Diaz  F Francés  D Corella  J Soler  J Tibau  L Gomez-Raya 《Zeitschrift für Tierzüchtung und Züchtungsbiologie》2012,129(4):289-297

The aim of this study was to investigate the phenotypic relationship between feed intake (FI) characteristics with intramuscular fat, cholesterol and fatty acid composition in pork. Data were available on 202 Duroc barrows. Intramuscular fatness was positively correlated with a higher percentage of saturated (SFA) and monounsaturated fatty acids (MUFA), a lower percentage of polyunsaturated (PUFA), omega-3 (ω3) and omega-6 (ω6) fatty acids, and a lower ω6/ω3 and P:S ratio (p < 0.05). Faster growth resulted in a higher level of SFA and a lower level of ω3 fatty acids (p < 0.05). Increased FI, residual feed intake (RFI) and feed intake time (TIME) and a decreased feed intake frequency (FREQ) resulted in an increase in MUFA, a decrease in PUFA, ω3 and ω6 fatty acids and a lower P:S ratio (p < 0.05). In addition, increased FI and RFI and a decreased FREQ resulted in an increase in SFA (p < 0.05). Most of the correlations were a result of a concomitant relationship with intramuscular fatness and disappeared after correction for that trait. Serum total, high-density lipoprotein and low-density lipoprotein cholesterol levels were positively correlated with SFA and MUFA, and negatively with PUFA, omega-3 and omega-6 fatty acids, and the P:S ratio (p < 0.05). These results have implications for programmes aimed at improving meat quality through selection.  相似文献   

Foliar anatomical and morphological variation in Nothofagus pumilio seedlings under controlled irradiance and soil moisture levels     

Ivancich HS  Lencinas MV  Pastur GJ  Esteban RM  Hernández L  Lindstrom I 《Tree physiology》2012,32(5):554-564

Foliar anatomy and morphology are strongly related to physiological performance; therefore, phenotypic plasticity in leaves to variations in environmental conditions, such as irradiance and soil moisture availability, can be related to growth rate and survivorship, mainly during critical growth phases, such as establishment. The aim of this work was to analyze changes in the foliar internal anatomy (tissue proportions and cell dimensions) and external morphology (leaf length, width and area) of Nothofagus pumilio (Poepp. et Endl.) Krasser seedlings growing in a greenhouse under controlled irradiance (three levels) and soil moisture (two levels) during one growing season (measured three times), and to relate them to physiological traits. Three irradiance levels (4, 26 and 64% of the natural incident light) and two soil moisture levels (40 and 80% soil capacity) were evaluated during November, January and March. Internal foliar anatomy of seedlings was analyzed using digital photographs of histological cuttings, while leaf gross morphology was measured using digital calipers and image analysis software. Most internal anatomical variables presented significant differences under different irradiance levels during the growing season, but differences were not detected between soil moisture levels. Palisade parenchyma was the tissue most sensitive to irradiance levels, and high irradiance levels (64% natural incident light) produced greater values in most of the internal anatomical variables than lower irradiance levels (4-24% natural incident light). Complementarily, larger leaves were observed in medium and low irradiance levels, as well as under low soil moisture levels (40% soil capacity). The relationship of main results with some eco-physiological traits was discussed. Foliar internal anatomical and external morphological plasticity allows quick acclimation of seedlings to environmental changes (e.g., during harvesting). These results can be used to propose new forest practices that consider soil moisture and light availability changes to maintain high physiological performance of seedlings.  相似文献
