Capture and restraint can induce stress in wild animals and tranquilizers may be beneficial in preventing some of the more adverse effects. A short-acting neuroleptic agent (acepromazine) was assessed in 25 Spanish ibexes (Capra pyrenaica) captured by drive-net. The animals were divided into a control group (14 ibexes) and a treated group (11 ibexes). Heart rate and rectal temperature, as well as haematological and biochemical parameters, were used to evaluate the effects of tranquilization during 3 h of restraint. A reduction in rectal temperature, red blood cell count, packed cell volume, haemoglobin concentration, white blood cell count, lymphocytes, neutrophils, activities of creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and concentrations of urea, total bilirubin and potassium in the treated group, suggested that acepromazine decreased signs of stress in Spanish ibex following drive-net capture.  相似文献

Irrigated agriculture in the Guadiana River high basin (Castilla-La Mancha, Spain): environmental and socioeconomic impacts   总被引：1，自引：0，他引：1  

Gregorio Lpez Sanz 《Agricultural Water Management》1999,40(2-3):171-181

This article is concerned with the management of the Guadiana River high basin's water resources. The region of Castilla-La Mancha in general, and Western La Mancha and the Campo de Montiel in particular, are areas where agriculture has great economic importance. This activity is the principal water consumer, but it is necessary to take account of ecological and social considerations if two important objectives are to be achieved. Firstly, to keep wetlands and biodiversity. Secondly, to maintain natural resources which are vital if the area's future is to be assured. The paper criticizes the mechanical and partial methodological focus which has been used by conventional economics and agriculture. Thus, it supports an integrated and multidisciplinary view that recognises the region's biophysical and social characteristics in such a way that policies applied respect it.  相似文献   

MAGNETIC RESONANCE IMAGING OF THE NORMAL EQUINE BRAIN     

Alberto  Arencibia  DVM  PhD  Jose M.  Vazquez  DVM  PhD  Juan A.  Ramirez  MD  PhD  Gregorio  Ramirez  DVM  PhD  Jose M.  Vilar  DVM  Miguel A.  Rivero  DVM  Santiago  Alayon  MD  Francisco  Gil  DVM  PhD 《Veterinary radiology & ultrasound》2001,42(5):405-408

The purpose of this investigation was to define the magnetic resonance (MR) imaging appearance of the brain and associated structures of the equine head. MR images were acquired in oblique dorsal (T2-weighted), sagittal (T1-weighted), and transverse planes (T2-weighted), using a magnet of 1.5 Tesla and a human body coil. Relevant anatomic structures were identified and labeled at each level. The resulting images provided excellent anatomic detail of the cranioencephalic structures. Annotated MR images from this study are intended as a reference for clinical imaging studies of the equine head, specially in the diagnosis of brain diseases in the horse.  相似文献   

Biochemical analysis of neoplastic versus nonneoplastic abdominal effusions in dogs     

Nestor DD  McCullough SM  Schaeffer DJ 《Journal of the American Animal Hospital Association》2004,40(5):372-375

This prospective study of 15 dogs evaluated biochemical parameters in abdominal effusions of neoplastic and nonneoplastic origin in an attempt to identify markers for malignant effusions. Dogs in the neoplastic group had statistically significant lower glucose concentrations (mean, 72.6 mg/dL versus 110.0 mg/dL; P=0.0431) and higher lactate levels (mean, 3.81 mmol/L versus 1.68 mmol/L; P=0.0377) in their abdominal fluid than did dogs in the nonneoplastic group, indicating that low glucose and high lactate in abdominal effusions may be markers for neoplasia.  相似文献

Influence of pasture sward height and concentrate supplementation on intake, digestibility, and grazing time of lactating beef cows     

Gekara J  Prigge EC  Bryan WB  Schettini M  Nestor EL  Townsend EC 《Journal of animal science》2001,79(3):745-752

To establish the effect of sward height (SH) and concentrate supplementation on performance of grazing cattle, 24 crossbred Angus beef cows (535 kg BW) and calves (114 kg BW) were grouped by weight and calving date. They were randomly assigned to two SH treatments, either 4 to 8 cm or 8 to 11 cm, and fed three levels of supplement, high, low, or none, consisting of 6.24, 3.12, and 0 kg x animal(-1) x d(-1), respectively. The experiment was repeated over three 15-d periods in 1996: May (P1), June/July (P2), and August (P3). No SH x supplement level x period or SH x supplement level interactions (P > 0.10) were evident for responses tested. Cows on lower SH had greater (P < 0.08) DMI but spent an additional 1.3 h/d (P < 0.01) grazing compared with cows on higher SH. Sward height had no influence (P > 0.10) on forage DM digestibility (DMD). Forage DMI, DMD, and grazing time (GT) decreased (P < 0.05) as supplementation increased. Nonetheless, supplemented cows consumed more total DMI (P < 0.08) than unsupplemented cows. Cows consumed 2.4 kg/d more forage DM (P < 0.01) in P1 and P2 than in P3. Cows grazed 1.3 h/d (P < 0.01) less in P1 than in P2 and P3. Grazing efficiency (DMI/h GT) declined as supplementation increased and grazing season advanced to P3 (P < 0.01). Decreased forage DMI and grazing efficiency with increasing supplementation suggests that supplemented cattle should be able to maintain productivity while grazing at SH lower than unsupplemented cattle.  相似文献   

Identification of Atlantic bluefin tuna (Thunnus thynnus) stocks from putative nurseries using otolith chemistry     

Jay R. Rooker  David H. Secor  Vincent S. Zdanowicz  Gregorio De Metrio  Lidia Orsi Relini 《Fisheries Oceanography》2003,12(2):75-84

Chemical signatures in the otoliths of teleost fishes represent natural tags that may reflect differences in the chemical and physical characteristics of an individuals' environment. Otolith chemistry of Atlantic bluefin tuna (Thunnus thynnus) was quantified to assess the feasibility of using these natural tags to discriminate juveniles (age 0 and age 1) from putative nurseries. A suite of six elements (Li, Mg, Ca, Mn, Sr and Ba) was measured in whole otoliths using solution‐based inductively coupled plasma mass spectrometry. Otolith chemistry of age‐1 T. thynnus collected from the two primary nurseries in the Mediterranean Sea and western Atlantic Ocean differed significantly, with a cross‐validated classification accuracy of 85%. Spatial and temporal variation in otolith chemistry was evaluated for age‐0 T. thynnus collected from three nurseries within the Mediterranean Sea: Alboran Sea (Spain), Ligurian Sea (northern Italy), and Tyrrhenian Sea (southern Italy). Distinct differences in otolith chemistry were detected among Mediterranean nurseries and classification accuracies ranged from 62 to 80%. Interannual trends in otolith chemistry were observed between year classes of age‐0 T. thynnus in the Alboran Sea; however, no differences were detected between year classes in the Tyrrhenian Sea. Age‐0 and age‐1 T. thynnus collected from the same region (Ligurian Sea) were also compared and distinct differences in otolith chemistry were observed, indicating ontogenetic shifts in habitat or elemental discrimination. Findings suggest that otolith chemistry of juvenile T. thynnus from different nurseries are distinct and chemical signatures show some degree of temporal persistence, indicating the technique has considerable potential for use in future assessments of population connectivity and stock structure of T. thynnus.  相似文献

Susceptibility of phaseolin to in vitro proteolysis is highly variable across common bean varieties (Phaseolus vulgaris)     

Montoya CA  Leterme P  Victoria NF  Toro O  Souffrant WB  Beebe S  Lallès JP 《Journal of agricultural and food chemistry》2008,56(6):2183-2191

A study was conducted to investigate the amino acid (AA) composition and the susceptibility to in vitro proteolysis (pepsin, 120 min and pancreatin, 240 min) of a collection of purified phaseolins ( n = 43) in unheated or heat-treated form. The AA composition of phaseolin varied little across bean varieties. At 360 min of in vitro proteolysis, the degree of hydrolysis varied from 11 to 27% for unheated and from 57 to 96% for heated phaseolins ( P < 0.001). Heat treatment markedly increased the susceptibility of phaseolin to proteolysis ( P < 0.001). The AA scores (AAS) and the protein digestibility corrected for AAS indicated S-containing AA as the limiting AA (39 +/- 3 and 30 +/- 5%, respectively). In conclusion, susceptibility to proteolysis of heat-treated phaseolin rather than its AA composition affects the nutritional value of phaseolin estimated in vitro. Therefore, it should be the criterion of choice in breeding programs aimed at improving the nutritional value of common beans for humans.  相似文献
