Lymphocyte antigen (BoLA) typing on 247 Baoule cattle (Bos taurus) and 106 Sudanese zebus (Bos indicus), allowed us to determine gene frequencies of 43 class 1 specificities, as international "W" and European "EU", as African local from Kenya "KN" and Burkina Faso "BF". In comparing these frequencies, it appears that some specificities could be considered as significant breed markers for Baoule cattle and zebus.  相似文献

1. Studies were conducted to determine the effects of anticoagulants and storage (4°C) on the PCV of blood samples from Nigerian domestic fowl (DF) and the guinea fowl (GF).

2. Citrate significantly reduced pre‐storage PCV of the DF in comparison with the effect of ethylenediamine tetra‐acetic acid (EDTA).

3. It further decreased (P<0.05) the PCV of the blood of DF and GF over 3 d of storage; this was similar to the effect of EDTA on the PCV of the GF blood.

4. Citrate and oxalates induced haemolysis of blood of the DF and the GF in storage faster than EDTA, but overall the haemolysis was more pronounced from red cells of the GF than from those of the DF.

5. The mean fall in the PCV of the DF was significant at 3.0 mg EDTA/ml of blood in contrast to the fall in the PCV of the GF blood.  相似文献

Recent publications dealing mainly with the kinetics of antiparasitic and antibacterial agents, NSAIDs, and other drugs in camels are briefly reviewed. The kinetic data for most of these drugs indicated that they have longer absorption and elimination half-lives and slower systemic clearance in the camel compared to other animals. This corroborates earlier reports that suggested that the activities of drug-metabolizing enzymes and the capacity to biotransform and eliminate xenobiotics is lower in camels than in other ruminants. There is a clear need to establish basic kinetic data for the camel in order to avoid extrapolation of drug dosage regimens and withdrawal times from data for other animals, as this may result in irrational use of drugs in camels.  相似文献

During the past decade, Fascioloides magna, the large American liver fluke, has spread within free-living deer in wetlands of the Danube in Lower Austria. The aim of this study was to determine the current infection rates with F. magna and other digenean parasites in the intermediate host snail Galba truncatula from risk areas in Lower Austria. A total of 3444 G. truncatula were collected and examined microscopically for the presence of digenean trematodes. A set of randomly selected snails and isolated trematode stages were also investigated molecular biologically by PCR and sequencing. Digenean parasites were detected with a prevalence of 2.41% (1.83% Paramphistomoidea; 0.46% Echinostomatoidea; 0.09% Strigeida; 0.06% Plagiorchiida). F. magna was found with an overall prevalence of 0.23%, which may indicate a recovery of the parasite population in spite of an ongoing triclabendazole treatment programme. Moreover, high risk areas and a seasonality of infections were observed.  相似文献

The influence of clofibrate on the stereoconversion of fenoprofen (FPF) was studied in guinea pigs. This hypolipidaemic agent has been related to some biochemical changes in the liver leading to an increase in the chiral inversion process. Two groups of animals (n = 6 per group) were pretreated with oral doses of clofibrate (280 mg/kg per day) for three days and were then given (R)- or (S)-FPF (5 mg/kg, IV). The FPF enantiomers were extracted from the guinea-pigs' plasma using a solid phase procedure and analysed by HPLC with previous derivatization with L-leucinamide. Pretreatment with clofibrate increased the chiral inversion of (R)-FPF in favour of the pharmacologically active (S)-FPF enantiomer. Before this metabolic interaction can be applied to therapy with fenoprofen, the toxic effects of (S)-(+)-FPF on the gastrointestinal and renal tracts and the interference by (R)-(–)-FPF with the metabolism of lipids should be thoroughly evaluated.  相似文献

The impact of replacing soybean crude protein (CP) with CP from ensiled taro leaves (ET) on growth performance, carcass traits, and organ weights in Landrace × Yorkshire (LY) and Moo Lath (ML) Lao pigs was studied. Twenty-four castrated male pigs, 12 of each breed, were allocated to the treatments according to a completely randomized 3?×?2 factorial (three levels of ET × two breeds) arrangement with four pigs per treatment. The pigs were kept in individual pens and were fed at 4 % dry matter of body weight for 105 days. The control diet (ET0) was formulated with soybean meal as the main CP source, and in the other two diets, soybean CP was replaced to 25 % (ET25) and 50 % (ET50), respectively, with CP from ensiled taro leaves. Calculated metabolizable energy intake decreased with increasing replacement of soybean CP in the diet, while dry matter intake (DMI), CP intake (CPI), average daily gain (ADG), and feed conversion ratio (FCR) were unaffected. Carcass weight, back fat thickness, and dressing percentage were unaffected by soybean CP replacement, while organ weights (except for spleen) increased (P?<?0.001) when soybean CP was replaced by CP from ensiled taro leaves in the diet. LY pigs had higher (P?<?0.001) DMI, CPI, and ADG and better (P?<?0.001) FCR than ML pigs. LY pigs had higher carcass weight (P?<?0.001), lower back fat thickness (P?<?0.001), and higher organ weights (P?<?0.05–0.001) than the ML pigs. In conclusion, taro leaf silage can replace up to 50 % of soybean CP in the diet of growing Lao LY and ML pigs without negative effects on performance and carcass traits.  相似文献

The aim of the study was to evaluate the pharmacokinetics of flurbiprofen (FBP) in different age groups and physiological status groups in dairy cattle. Ten Argentine Holstein bovines were divided into three different groups: 3 cows in early lactation, 3 cows in gestation and 4 newborn calves. Based on previous experience, all the animals received racemic FBP (50:50) at a dose of 0.5 mg/kg by intravenous administration. Blood samples were taken at predetermined times after administration of flurbiprofen. Plasma enantiomer concentrations were measured by HPLC. Total body clearance (ClB) of (S)-(+)-FBP was higher in calves than in cows (114.5, 136.4, 121.4, 128.9 μg/ml vs 22.0, 24.2, 46.5 μg/ml and 27.6, 25.3, 34.6 μg/ml). In calves the disposition kinetics showed stereoselective behaviour. Area under the concentration–time curve (AUC) was higher and ClB and steady-state volume of distribution (Vss) were lower for (R)-(−)-FBP than for (S)-(+)-FBP. In cows, stereoselectivity was observed in ClB and elimination half-life (fract12)(frac{t_1}{2}) only in the early lactation group. In this study, enantioselective metabolic behaviour of FBP under the physiological situations studied was found. Hence, it is possible that both enantiomers of flurbiprofen may contribute to the drug's therapeutic effects, but further studies with the administration of separate enantiomers will be required to elucidate their metabolism.  相似文献

Three cases of fibroepithelial hyperplasia (FEH) of the mammary gland in the cat are reported. A one year old female cat had a distinct enlargement of the middle mammary glands, one on each side, 5 days after the first estrus. One week later the cat was treated with medroxyprogesterone acetate (Depo-Promone). The affected glands, along with the remaining glands, increased further in size. A five year old female cat was treated with Proligeston (Covinan) for the suppression of estrus. Two weeks later fibroepithelial hyperplasia occurred in two glands, one with a well demarcated ulceration. A seven months old male cat was treated with delmadinon acetate (Tarden) because of urine spraying. Two months later he had enlargement of all mammary glands. All three cats were treated with the progesterone antagonist Aglépristone (Alizine). Within 5 to 11 weeks the mammary glands had regressed to normal.  相似文献

Disorders of the horizontal ramus (body) of the equine mandible are well reported, but there is minimal documentation of disorders of the angle of mandible. A retrospective examination of the records of Edinburgh University Equine Hospital (1997–2011) showed that 32 horses were referred due to swellings of the angle of the mandible. The aetiology of these swellings was identified in just 13/32 cases (41%) including fractures (n = 2), traumatic, localised periosteal/cortical lesions (n = 4), traumatic soft tissue lesions (n = 2), neoplasia (n = 3), and inflammation of the adjacent salivary gland (n = 1) and masseter muscle (n = 1).The remaining 19 (59%) cases without a definitive diagnosis showed two patterns of lesions. Twelve cases had localised periosteal/cortical lesions of the ventral aspect of the angle of mandible that were most likely traumatic in origin. The remaining seven undiagnosed cases without mandibular bony changes all had sinus tracts/chronic soft tissue infections on the medial aspect of the angle of the mandible which were believed to be caused by a draining retro-pharyngeal lesion in five cases. Surgical excision of abnormal soft tissues (if present) and bone curettage was the most successful treatment.It was concluded that the aetiology of swellings of the angle of the equine mandible are often obscure; most appear to be traumatic in origin, yet horses seldom develop gross fractures at this site due to the support of the dense surrounding musculo-tendinous structures. A smaller proportion are caused by draining retropharyngeal lesions that respond poorly to medical therapy, but respond well to surgical treatment.  相似文献

Current study aimed to determine possible differences in plasma leptin levels during the prepuberal period and their relationship with the onset of puberty in gilts of obese thrifty genotype (Iberian breed) and lean genotype (Large White × Landrace commercial crosses) reared under similar conditions. Plasma leptin concentration increased linearly during the 7 weeks prior to the day of puberty attainment in both genotypes (P<0.005, r=0.707 for LW × L and P<0.0005, r=0.874 for Iberian gilts). However, leptin levels in the Iberian gilts was higher from the first sample of the experimental period, with females having 16 weeks-old (2.7±0.3 vs 1.7±0.2 ng/ml in LW × L; P<0.001), to the onset of puberty (8.5±0.7 vs 2.8±0.3 ng/ml in LW × L; P<0.005). Thus, the current study reinforces previous data on changes in around puberty and evidences, for the first time, profound differences in prepuberal plasma leptin levels between gilts of obese (Iberian) and lean genotypes (LW×L).  相似文献

Hypothesis/ObjectivesTo describe the therapeutic use of pimobendan in cats, describe the patient population to which it was administered, document potential side effects and report the clinical course following administration of pimobendan in conjunction with standard heart failure therapy. It is hypothesized that cats with advanced heart disease including congestive heart failure from a variety of causes will tolerate pimobendan with a minimum of side effects when used in treatment in conjunction with a variety of other medications.Animals, materials and methodsOne hundred and seventy client owned cats with naturally occurring heart disease, one hundred and sixty four of which had congestive heart failure. Medical records were reviewed and owners and referring veterinarians were contacted for follow-up data. Data collected included pimobendan dose, other medications administered concurrently, data collected at physical examination, presence or absence of heart failure, adverse effects, classification of heart disease, echocardiographic data and survival time. The data were analyzed for significance between the initial visit and any follow-up visits.ResultsAll cats were treated with pimobendan. The median pimobendan dose was 0.24 mg/kg q 12 h. Pimobendan was used in combination with multiple concurrent medications including angiotensin converting enzyme inhibitors, diuretics and anti-thrombotics. Five cats (3.0%) had potential side effects associated with pimobendan. One cat (0.6%) had presumed side effects severe enough to discontinue pimobendan use. Median survival time for 164 cats with congestive heart failure after initiation of pimobendan was 151 days (range 1–870).ConclusionPimobendan appears to be well tolerated in cats with advanced heart disease when used with a variety of concurrent medications. Randomized controlled studies need to be performed to accurately assess whether it is efficacious for treatment of congestive heart failure in cats.  相似文献

Objective

The fixed-dose combination of butorphanol, azaperone and medetomidine (BAM; 30, 12 and 12 mg mL?1, respectively) with subsequent antagonism by naltrexone–atipamezole was evaluated for reversible immobilization of captive blesbok (Damaliscus pygargus phillipsi).

Study design

Prospective, clinical trial.

Animals

Sixteen blesbok (four males and twelve females), weighing 52.5?71.0 kg, were immobilized in South Africa.

Methods

The total dose of BAM ranged from 0.5 to 0.7 mL for females and 0.7 to 0.9 mL for males. In seven animals chosen randomly, 8000 units of hyaluronidase was added to the dart. Physiologic variables were recorded every 5 minutes beginning at 10?20 minutes after darting. Arterial blood samples were collected three times at 20, 30 and 40 minutes after darting for analysis of blood acid-base status.

Results

The mean administered doses of BAM were as follows: butorphanol (0.34 ± 0.08 mg kg?1), azaperone (0.14 ± 0.03 mg kg?1) and medetomidine (0.14 ± 0.03 mg kg?1). The inductions were calm and smooth. The mean induction time was 9.6 ± 3.2 minutes with just BAM and 5.1 ± 0.8 minutes with BAM and hyaluronidase combination. Heart rate (45 ± 6 beats minute?1) and respiratory frequency (38 ± 4 breaths minute?1) were stable throughout immobilization. The mean arterial blood pressure for all animals was stable but elevated (137 ± 7 mmHg). Rectal temperature slightly increased over time but remained within an acceptable range. The recovery time after administering naltrexone and atipamezole was 4.8 ± 0.7 minutes.

Conclusion and clinical relevance

The BAM combination proved to be reliable and effective in blesbok.  相似文献

Objective

The combination of butorphanol, azaperone and medetomidine (BAM) with subsequent antagonism by naltrexone–yohimbine or naltrexone–atipamezole was evaluated for reversible immobilization of captive African lions (Panthea leo).

Study design

Prospective, clinical trial.

Animals

Twenty lions, 11 males and nine females, weighing 38–284 kg were immobilized in South Africa.

Methods

The BAM volume dose rate administered was 0.005–0.008 mL kg?1 (0.6 mL 100 kg?1). Physiologic variables were recorded every 5 minutes. Four arterial blood samples were collected from all animals at 20, 30, 40 and 50 minutes after immobilization for analysis of blood-gases and acid-base status.

Results

The actual doses administered were as follows: butorphanol, 0.18 ± 0.03 mg kg?1; azaperone, 0.07 ± 0.01 mg kg?1; and medetomidine, 0.07 ± 0.01 mg kg?1. The inductions were calm and smooth, and induction time ranged from 4 to 10 minutes (7 ± 2 minutes). The amount of time needed to work with each lion was 70 minutes, and no additional drug doses were needed. Heart rate (40 ± 8 beats minute?1) and respiratory frequency (15 ± 4 breaths minute?1) were stable throughout immobilization. The mean arterial blood pressure of all animals was stable but elevated (142 ± 16 mmHg). The rectal temperature slightly increased over time but remained within acceptable range. The recovery time was significantly shorter when using naltrexone and atipamezole (9 ± 1 minutes) compared to using naltrexone and yohimbine (22 ± 7 minutes).

Conclusion and clinical relevance

The BAM combination proved to be reliable for general veterinary anaesthesia in lions. During anaesthesia, minor veterinary procedures such a blood collection, intubation, vaccination and collaring could safely be performed with no additional dosing required.  相似文献
