Effect of chronic heat load during pregnancy on birth weight,behaviour and body composition of Australian feral goat kids     

J. H. G. Holmes  S. Prasetyo  H. M. Miller  E. A. Scheurmann 《Tropical animal health and production》1986,18(3):185-190

Six feral does maintained at elevated ambient temperatures (27.2 degrees - 34.8 degrees) for the last half of pregnancy had rectal temperatures (Tr) elevated by 0.4 degrees above 10 unstressed does. Heat-stressed twin-bearers were 0.15 degrees hotter than single-bearers and bore lighter kids (1.70 kg), than unstressed does (2.24 kg) while singles were less affected (2.22 kg versus 2.28 kg). Birth weight was more highly correlated (P less than 0.001) with the daily minimum Tr of the dam than with the mean or maximum Tr. Kids from heated does stood and began sucking as quickly as control kids but during the first six hours scored significantly (P less than 0.01) lower on a scale of general activity. There were no significant differences in body content of nitrogen, fat and ash or, when birth weight was considered, weight of hide, CNS and liver.  相似文献

RADIOGRAPHIC AND ANGIOGRAPHIC EVALUATIONS OF FERRETS EXPERIMENTALLY INFECTED WITH DIROFILARIA IMMITIS

Five ferrets of each sex were each inoculated with 15 third-stage infective larvae of Dirofilaria immitis to study radiographic and angiographic changes in the cardiopulmonary system following heartworm infection; 5 additional ferrets of each sex served as noninfected controls. Prior to inoculation and every 8 weeks thereafter until 40 weeks, the infected and noninfected ferrets were radiographed; angiographic examinations were done prior to necropsy. At necropsy, the worms in the heart, lungs, and associated vessels were counted, and lung histosections were prepared and examined for changes. Radiographic changes were seen in the right side of the heart and associated vessels of infected ferrets as compared with the noninfected ferrets, but changes were less prominent than those seen in heartworm-infected dogs and cats. The changes were primarily an increase in the size of the right side of the heart, especially the right atrium. Radiographically, no changes could be visualized in the pulmonary vascular system. Worms in the enlarged cranial vena cava, azygous vein, and left caudal lobar pulmonary artery of infected animals were delineated by angiography. Histologically, no changes were seen in the pulmonary vascular tissues.  相似文献

The pathophysiology of ovine trypanosomosis: haematological and blood biochemical changes.     

E Katunguka-Rwakishaya  M Murray  P H Holmes 《Veterinary parasitology》1992,45(1-2):17-32

The course of Trypanosoma congolense infection in sheep was followed for 96 days. Infected animals developed fluctuating parasitaemia, macrocytic normochromic anaemia and leucocytosis which was principally a lymphocytosis. Following treatment with the trypanocidal drug, diminazene aceturate at 84 days after infection, the haematological values returned to normal within 12 days. Infected sheep developed hypocholesterolaemia and hypophospholipidaemia leading to a reduction in total serum lipids. This study has shown that sheep infected with T. congolense develop anaemia, the onset of which follows the first wave of parasitaemia. The changes in blood lipids observed in infected sheep appeared to be related to the intensity and duration of parasitaemia.  相似文献   

In vitro production of specific antibody by equine peripheral blood mononuclear cells using tetanus toxoid as a recall antigen.     

M A O'Brien  M A Holmes  W P Duffus 《Research in veterinary science》1992,53(2):184-190

Anti-tetanus toxoid (TT) antibody (Ig) levels in the supernatant of cultured, pre-immunised equine peripheral blood mononuclear cells (PBMC) were measured by an indirect enzyme-linked immunoabsorbent assay (ELISA). Optimal anti-TT Ig production occurred at concentrations of stimulating, purified TT of between 0.001 and 0.1 micrograms ml-1, which varied depending on the cell concentration. Optimal anti-TT Ig production was most consistently produced when the cell concentration was 5 x 10(6) ml-1. At this cell concentration maximal anti-TT Ig was induced using 0.1 micrograms ml-1 TT. At a cell concentration of 5 x 10(6) ml-1 and a TT concentration of 0.1 micrograms ml-1 anti-TT Ig was first detectable in supernatant on day 5 of stimulation. Maximal levels of anti-TT Ig were present in the supernatant by day 10. No anti-TT Ig was produced in cultures of PBMC from non-immune animals.  相似文献   

Three cases of ruptured mitral valve chordae in the horse   总被引：1，自引：0，他引：1  

J R Holmes  P J Miller 《Equine veterinary journal》1984,16(2):125-135

The paper describes clinical observations in three horses with ruptured mitral valve chordae. Horses with ruptured mitral valve chordae may have a history of sudden onset of acute distress with predominantly respiratory symptoms. On auscultation there will be a widespread pansystolic murmur with an extension of the area of cardiac auscultation. The third heart sound may be very pronounced and unduly prolonged, associated with high volume flow during early ventricular filling in diastole. However, these sounds are not specific for chordal rupture--they are typical of severe mitral regurgitation. The electrocardiogram may show predominantly backward spatial vectors during ventricular depolarisation. The condition gives rise to left ventricular volume overload and pulmonary hypertension would be expected in horses showing signs of cardiovascular disturbance or those recently affected. Care is necessary during post mortem examination to avoid cutting through the mitral valve before a proper assessment has been made of the chordal insertions.  相似文献
