The bone mineral density BMD and content BMC were analysed in the tibiotarsal bones of ducks in the postnatal development as influenced by age and sex. One hundred birds from the nesting till the slaughtering maturity were included in the experiment. The analysis was conducted using a densitometer, Norland - Excell Plus and pQCT computed tomography, XCT Research SA Plus. The statistical analysis was...
The bone mineral density (BMD) and the bone mineral content (BMC) in the bone tissue of the bilateral first phalanges of horses’ thoracic limbs were analysed. The research material consisted of isolated pastern bones derived from 22 horses. The research was conducted with the use of a Norland model Excell Plus densitometer (Fort Atkinson WI, USA), using affinited beam X-ray technology and an animal...
The aim of the study was to compare densitometric and geometric parameters of the proximal phalanges in forelimbs of Wannblood and Coldblood horses, at 15%, 50%, and 85% of the bone proximal length. Peripheral quantitative computed tomography was used to analyse the structure of phalanges. The following parameters were determined: bone mineral content, volumetric bone mineral density, total bone area,...
The aim of the study was to analyse densitometric and geometric parameters of healthy and deformed tibiotarsal bones of male turkeys of heavy type with the use of computed tomography. The influence of a bone type (healthy or deformed) and the area of the measurements (the proximal metaphysis and middle of the diaphysis) on these parameters were studied. It was found that the diaphysis of the deformed...
Celem badań była ocena wzrostu i wartości rzeźnej kaczek odchowywanych do wieku 7 tygodni. Materiałem badawczym były kaczki Pekin STAR 53 HY (120 samic i 120 samców). W okresie odchowu kontrolowano masę ciała ptaków, a po zakończeniu odchowu przeprowadzono ubój 15 kaczorów i 15 kaczek. Następnie przeprowadzono analizę rzeźną i dysekcyjną ptaków. Między 1. a 49. dniem życia kaczory zwiększyły swoją...
The influence of sex on bone mineral density (BMD) and the bone mineral content (BMC) have been analysed in selected bones of the thoracic and pelvic limbs of African ostriches. The examination was conducted with the use of a densitometer, using the technology of affinited beam of X-ray and the programme for animal research. It was shown that the analysed bones of ostrich skeleton differed significantly...
An anatomical study was conducted on fresh hearts of 12 wild boar males and hearts of 12 domestic pigs (5 males and 7 females). Several linear and weight measurements of the heart were taken: height measured from the heart's apex up to the end of the atria, width measured in the area of the coronal fissure, circumference measured in the area of the coronal fissure, right ventricle weight, left ventricle...
The proximal phalanges, especially those of the thoracic limbs of horses, are the ones most exposed to injuries in the species. Due to unequal loading of the lateral pastern bones resulting from the specific training of racehorses in Poland and from the way races are conducted, the authors of the publication aimed at a detailed quantitative profile based on a radiogram analysis of the lateral proximal...
The aim of this research was to evaluate the existence of sexual dimorphism in the horse larynx as far as morphology, absolute and relative dimensions, and the weight of the organ, were concerned. The material consisted of the larynxes, taken from 20 adult horses of both sexes. The larynxes were examined morphologically, weighed, and linear, angular, and surface measurements were taken. It was found...
The publication presents the pathological changes occurring in well-preserved excavated bones of horses from the Middle Ages in the form of photographs and analysis of visible pathologies in comparison to bone diseases observed nowadays. The material came from different areas of Poland and belonged to the Centre of Archaeological Research of Warsaw University, being at the same time a kind of unique...
A novel diagnostic method was adapted from studies in horses and humans to postmortal research on ostrich bones. The research made it possible to determine referential values in the method of digital analysis of a radiological image for the tibio-tarsal bone of the ostrich, following exposure to injuries. In the case of a computer-generated analysis of a radiological image, the optimal conditions...
The aim of the research was investigate the morphology of the limb girdle and free part of the pelvis limb of the ostrich as well as to establish the measurements of individual bones and determine dismorphic and ontogenetic differences. Studies were conducted on bone material derived from skeletons of fourteen-month-old ostriches (10 males and 10 females). After preparing the research material, absolute...
The aim of the morphological research was to attempt to characterize the peripheral part of the pelvis limb of domesticated ducks in relation to their age and sex. Research was conducted on the bone material of domestic Peking ducks (Anas platyrhynchos f. domestica Linnaeus 1758) derived from 84 8-week-old ducks (42 males and 40 females) and 40 ducks over eight weeks old (6 males and 34 females)....
