The aim of the study was to analyse densitometric and geometric parameters of the compact bone and the trabecular diaphysis of the femur of ostriches with the use of computed tomography. The method has been applied in ostriches for the first time. The study was conducted on the femur of 14-month-old ostriches of both sexes. The obtained results were analysed statistically using one-way ANOVA, with Bonferroni correction for multiple-group comparisons. It was stated that the mineral content (BMC) in the middle of the diaphysis of the femur was significantly higher in males (465.52 mg/mm) than in females (417.67 mg/mm). Similar tendencies were observed for the total bone area (TOT_ A), trabecular area (TRAB_ A), cortical area (CRT_ A), and strength strain index (SSI). The average area of the CRT_A for both sexes was 568.62 mm² and was lower than the TRAB_A - 884 mm², at P≤0.05. Moreover, it was found that strength strain index (SSI) of the diaphysis depended on the TOT_A and the TRAB_A. Both features positively correlated with SSI. Pearson's correlation coefficient for both features was r = 0.97, at P≤0.01. Further research concerning the dynamics of changes of densitometric and geometric parameters occurring with age and involving both sexes is recommended, as there are many locomotion problems in ostriches, especially older ones, used intensively on farms for many years.
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 regarding the BMD and BMC. Significantly higher values of both parameters were recorded in case of the bones of the pelvic limb in comparison with the bones of the thoracic limb. A central part of the shaft of the tibio-tarsal bone and its proximal end (the pelvic limb) were characterised by the highest values for both BMD and BMC, whereas for the ulnar and radial bones (the thoracic limb) the lowest values were obtained. The study also demonstrated that males showed a significantly higher BMD and BMC values than females referring to the pelvic bones, i.e. the tibio-tarsal bone. For further study aiming at monitoring changes in BMD and BMC during the growth and development of ostriches from hatching till the 14th month of life, the use of densitometer intravitally is recommended.
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 conducted using the Kruskal-Wallis one-way analysis of variance (age) and the U-Mann -Withney test (sex). All calculations were performed in Statistica 9.0 (StatSoft, Inc. Tulsa, USA), at P ≤ 0.05. Two-factor analysis of variance ANOVA was applied and Pearson’s correlation coefficients were calculated. The densitometer research showed that BMD and BMC increased in the postnatal development for both sexes. The volumetric bone mineral density vBMD analysis using computed tomography showed that volumetric bone mineral density vBMD of the middle of the diaphyses in situ gradually attenuated during the postnatal development both in males and females, i.e. from 620 mg/cm3 (2 wk) to 500 mg/cm3 (8 wk). The biggest vBMD loss was observed in the diaphyses of females in 4 and 6 wk (r = - 0.63 and r = - 0.79; P ≥ 0.05). The BMC decrease was observed in the proximal metaphyses between 4 and 6 wk for both sexes, r = - 0.52 (males), r = - 0.53 (females); P ≤ 0.05. The gradual loss may be the cause of deformities and fractures of the tibiotarsal bones observed from 4 wk in particular bone sections of both sexes. The achieved results may constitute a helpful source of information for water poultry breeders to prevent limb diseases.
Methods for the evaluation of the parameters of bone tissue and their characteristics are presented. The development of modern methods and their possible application in veterinary orthopedic diagnosis is discussed. Primarily computerized assisted analysis of bone structure images on the radiograph are described.
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). All the birds were from a water-fowl farm. The bones were cooked in a 3% solution of sodium bicarbonate (NaHCO3), bleached with hydrogen peroxide (H2O2) and then dried at room temperature (16-20°C). The research concentrated on the bones of the peripheral part of the pelvis limb and, in particular, on a detailed morphological analysis of the bones of the left limb. Features typical of the species as well as changes concerning dimorphism and ontogeny were analysed. Statistically significant major differences were found between analogical bone parameters in adult males and females. No changes related to sexual dimorphism were observed in the cases of phalanx I greatest length (GL) and breadth of the proximal end (Bp), phalanx II of toe I and breadth of the proximal end (Bp), phalanx II of toe II and greatest length (GL), breadth of the proximal end (Bp), phalanx III of toe III and breadth of the proximal end (Bp). Dimorphic changes were also not found in phalanx I greatest length (GL), phalanx II greatest length (GL), phalanx III greatest length (GL), phalanx V of toe IV. No sexual dimorphism in relation to the tarsal-metatarsal bone was found among young ducks. In this group of birds statistically significant differences were found for phalanx III greatest length (GL), breadth of the proximal end (Bp), phalanx IV of toe III greatest length (GL), breadth of the proximal end (Bp). While analyzing the structure of toe IV, sexual dimorphism was found only in the case of phalanx IV and breadth of the proximal end (Bp).
The aim of the morphological study was an attempt to define in a morphological context the shoulder girdle and epiphysis bones in the pelvic bone of the domestic Peking duck. The morphological study was performed on the bone material taken from skeletons of domestic Peking ducks (Anas platyrhynchos f. domestica, Linnaeus 1758) including 40 adult individuals (6 males and 34 females) and 84 young individuals (42 males, 42 females). After preparing the bones for the research the absolute parameters of the bones were estimated for both males and females separately taking into account different age groups. The analysis included osteometry and description of anatomic bone structures. There appeared to be statistically significant differences between similar bone parameters defined for adult male and female species. In the young bird group distinct sex dimorphism was observed only in the spinal length of the pelvis as well as in the greatest length and width of the fibula bone. There also appeared to be ontogenetic differences between young and adult ducks in the size of the bones examined. The adult male species were characterized by bigger bones of the pelvic limb part studied. Similar dependences were observed in the case of young species. However, dimorphic differences were more visible with adult species. The external surface carving becomes more distinct with the increase of the birds’ age.
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 research programme (Research Scan, 3.9.6. version) at the following parameters: scanning resolution of 1.5 x 1.5 mm, scanning speed 60 mm/s. The differences between BMC and BMD values in bilateral first phalanges in the thoracic limbs in horses were found to be nonsignificant. It also appeared that there are statistically significant positive correlations between values of the left and right bone of both analysed variables.
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, trabecular area, cortical area, cortical thickness, periosteal circumference, endocortical circumference, and strength strain index. The most significant differences between pastern bones in thoracic limbs of the horses were visible in the proximal and distal metaphyseal parts, for instance, at 15% and 85% of the bone length, respectively. Statistical analysis showed that at 15% of the bone length, total bone area, trabecular area, periosteal circumference, and endocortical circumference were significantly higher in Warmblood horses. At the mid-shaft, volumetric bone mineral density and endocortical circumference were significantly higher in Coldblood horses. At 85% of the bone length, volumetric bone mineral density, total bone area, trabecular area, periosteal circumference, and endocortical circumference were significantly higher in Coldblood horses.
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 that horse larynxes, were characterised by a practically unnoticed sexual dimorphism. The weight and size parameters of the larynxes were not directly connected with the weight of the whole body of the animal.

51%
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 średnią masę ciała z 55,5 do 2996,2 g, a kaczki z 51,7 do 2397,5 g. Między 2. a 7. tygodniem odchowu kaczek następowały korzystne zmiany w składzie tkankowym ich tuszek. W analizowanym okresie wyraźnie wzrastało umięśnienie tuszki z 17,8 do 26,8%, natomiast dość wyraźnie zmniejszała się zawartość kości (pozostałości tuszki) z 54,2 do 48,9% oraz nieznacznie otłuszczenie tuszki z 28,0 do 24,3%. Odchowując kaczki Pekin STAR 53 HY do wieku 7 tygodni uzyskuje się ptaki o średniej masie ciała 2697,0 g, tuszki o średniej masie 2073,9 g, w których skóra z tłuszczem podskórnym i sadełkowym stanowi 24,3%, mięśnie piersiowe, ud i podudzi – 26,8%, a kości (pozostałość tuszki) – 48,9%.
Background: Obstructive sleep apnoea (OSA) is characterised by repeated episodes of pauses in breathing during sleep due to obstruction of the upper airway that result in transient hypoxaemia, sleep fragmentation and long-term cardiovascular disease. The most common risk factors for OSA include: obesity, age over 50 and neck circumference of more than 41 cm for females and more than 43 cm in males. Sleep apnoea is more common in men than in women. The aim of the conducted research was to evaluate relations between the anthropometric features connected with adipose tissue distribution and the severity of OSA. Materials and methods: The study was carried out on 180 patients (144 males and 36 females) diagnosed with OSA syndrome. The standard sleep parameters obtained from night polysomnography as well as skin-fat fold thickness and neck circumference and waist-to-hip ratio were analysed. Statistical analysis was performed using STATISTICA 10. Results: It was stated that anthropometric parameters connected with the accumulation of adipose tissue in upper body were significantly related to severity of OSA in males (p ≤ 0.05). Body mass index (BMI) was significantly correlated with severity of OSA in females (p ≤ 0.05). Conclusions: In males, there is a connection between the severity of OSA, BMI and a higher accumulation of adipose tissue in upper part of the body measured by neck circumference and shoulder thickness of skin-fat folds, whereas in females only by BMI.

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 weight, the weight of both atria, and the weight of both ventricles. All the linear measurements were made using sliding dividers with accuracy of up to 1 mm, the weight parameters were determined using laboratory scales with accuracy of up to 0.01 g. Statistical analysis (t-Tukey's test) showed that three groups of animals, selected for this study differed significantly in regard to body mass, age, and mass of right vetricle. However, younger domestic animals had higher body mass. Wild boars had higher right ventricle mass. Relative heart weight expressed as a percentage of body weight was over two fold higher in wild animals (0.59%) than in domestic ones (0.28%).
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 exhibits in Poland. Most of the pathologically changed bones were limb bones.
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 parameters of the examined bone structures were established separately for males and females. Analysis included a description of anatomical bone structures and osteometry. Measurements of the length and width of such bones as the pelvis, femur, tibia-tarsal, tarso-metarsal and phalanges III and IV were ascertained during the research process according to methods suggested by Driesch (16). Individual measurements were used for the fibula in order to define the greatest width of the proximal end (NSKB) as well as its optimal length (ND). A set of vernier calipers was used to determine the width and the length of the bone exact to 0,1 mm. Significant sexual dimorphism was observed in the group of studied birds. The variables showing statistically significant differences were: the greatest width of the proximal end of the femur (FBp), the greatest length of the pelvis (GL), the width of the ilium (CB), the width of antitrochanter (BA), the diameter of the acetabulum (DiA). Variables of phalanx III were P3ND1, P3NSKB1, P3NSKD1, P3ND2, P3NSKB2, P3NSKD3 and P3ND4 and all of the studied parameters of phalanx IV indicated statistically significant differences. Clear sexual dimorphism was also found on the basis of measurements of the length (ND) and width (NSKB) of the fibula. Male pelvic bones were significantly bigger than those of females
