Balkan donkey is native breed of donkeys evolutively adapted to modest breeding conditions and different climatic systems including harsh and severe climate of Serbian mountains. Unfortunately, the purposes for breeding small donkeys have been lost during the 20th century so the population is regressing. There has been no selective breeding of the autochthonous donkeys in Serbia therefore the data on breed characteristics are recent and few. The monitoring of morphological characteristics of autochthonous Balkan donkey population in Serbia have been performed in aim to characterize the population and to define the importance of autochthonous donkeys as national genetic resource . The morphometric parameters evaluated i.e. height at withers (HWi) body length (BLe), thorax girth (TGi), cannon perimeter (CPe) and body weight (BW) in young Balkan donkeys bred in traditional conditions were used for establishment of the following body indexes: Index of Body Frame (IBF), Index of Body Compactness (BCI), Index of Conformation (CoI) and Dactyl-costal Index (DCI) reflecting body development and conformational relations in Balkan donkey population in Serbia.

Introduction. By the number of litters and puppies per year, the Posavatz hound is the second most common hound breed in Serbia. This hound is intensively used for hunting in Serbia, since these dogs show very good working characteristics. The aim of this study was to determine the extent to which the external characteristics of the population in Serbia meet the norms prescribed by the official standard for the breed. Materials and Methods. A total of 251 Posavatz hounds, i.e. 134 adult males and 117 adult females, were included in a morphometric evaluation of the population sub-sample during 2017 and 2018. The basic parameters of height at the withers, body length, chest circumference and head length were measured. The variability of the results obtained was statistically analyzed by Student?s t-test for distribution of the frequencies, while the heterogeneity/homogeneity of the evaluated morphometric parameters within the Posavatz breed was estimated by coefficient of variation. Results and Conclusions. The results showed the studied Posavatz hounds in Serbia are characterized by a proper rectangular body shape. However, the average body height tended to be too low, i.e. more towards the lower limit of the prescribed height at the withers. The morphometric deviations established when comparing the Posavatz hound population in Serbia with the standard for the breed should enlighten the guidelines for sound selective breeding of the Posavatz hound by contributing to decision making by breeders and expert commissions of canine organizations. Overall, this should allow healthy breeding and welfare maintenance throughout generations for this hound breed.

The effects of exercise and the combination of exercise and clenbuterol on progression of muscular dystrophy were studied in mdx mice. At 3 wk of age, mdx mice were randomly assigned to sedentary (MS), exercise (ME), or combined exercise and clenbuterol (MEC) groups. Clenbuterol was given in the drinking water (1.0-1.5 mg . kg body weight-1 . day-1), and exercise consisted of spontaneous running activity on exercise wheels. At 3 mo or 1 yr of age, ventilatory function, contractile properties, and morphological characteristics of the soleus (Sol) and diaphragm (Dia) muscles were measured. The mdx mice receiving clenbuterol ran less than the mice without clenbuterol. The combination of clenbuterol and exercise was associated with an increase in Sol muscle weight and a muscle weight-to-body weight ratio of 30-35% compared with the sedentary group and approximately 20% compared to exercise alone. Myosin and total protein concentrations of the Sol and Dia increased in the MEC group at 1 yr of age only. Normalized active tension was increased in the Dia at 1 yr of age in both the ME and MEC groups by approximately 30%. Absolute tetanic tension of the Sol was increased at both 3 mo and 1 yr of age in the MEC compared with the MS group. At 1 yr of age, there was an additional 23% increase compared with the ME group. Fatigability increased in the MEC group by approximately 25% in the Sol and Dia muscles at both ages compared with the MS and ME groups. Results indicate that exercise and exercise plus clenbuterol decrease the progression of muscular dystrophy. However, different mechanisms may be involved because the combination of clenbuterol and exercise resulted in increased fatigability and the development of deformities, whereas exercise alone did not. Therefore, clenbuterol may not be suitable for use in patients with muscular dystrophy.

The Way

Body-frame size is an important factor in determining an optimal body weight for a given height. Previous studies have indicated that many individuals incorrectly estimate their body-frame size, and, as a result, incorrectly assess their ideal weight. The present study investigated the accuracy of estimation of body-frame size as a function of sex and actual frame size. The subjects were 66 men and 52 women participating in a community adult fitness program. Data indicated that medium-framed individuals were the most accurate in their estimations of body-frame size. Also, women were twice as likely to be accurate as were men. These results are interpreted to mean that most people assume they are medium-framed and that there is a sex difference in the way body-frame size is estimated.

In this study, in order to help the mass production of seedlings, the effect of fertilization on the morphological development of hornbeam leafy European hophornbeam (Ostry carpinifolia Scop) seedlings were investigated. For this, seedlings, which were obtained from the seeds coming from different European hophornbeam populations (Düzce-Yığılca, Antalya-Finike, Antalya-Akseki, Kastamonu-Şehdağ ve Adana-Saimbeyli) from various parts of Turkey, were used. European hophornbeam seedlings were treated with different fertilizers, including urea, ammonium sulphate, compound fertilizer 15-15-15 and 20-20-0, and 6-9 months Osmocote release fertilizer, and effects of these fertilizers on the morphological characters were investigated. Fertilization contained the same amount of nitrogen, and was made in three different ways; (1) mixing with habitat, (2) topical application and (3) liquid application. The development of germinated European hophornbeam seeds, which were spring-sowed in the same medium were monitored during the vegetation period. At the end of vegetation period, seedlings were removed from the soil and morphological characteristics of root (seedling length, root collar diameter, root length, fresh root and stem weight of the seedlings, dried root and stem weight of the seedlings and bud number) were measured. As a result, it was observed that fertilization positively affects the development of seedlings and depending on the fertilization type the seedlings of European hophornbeam populations were found to exhibit different improvements/growing. In addition, 6-9 months Osmocote release fertilizers were determined to be the best fertilizers affecting the morphological (diameter and height) development of European hophornbeam populations effectively, and among the populations, Düzce and Kastamonu populations showed the best improvement/growing.

Purpose of the study: To register the dynamics of the basic parameters of the physical development of children from the fourth preparatory group, as a result of the implementation of an enriched educational content in physical culture pedagogical situations. 54 girls and 67 boys were investigated and measured twice – at the beginning and at the end of the pedagogical experiment. Anthropometric parameters assessed: height, body weight, chest circumference. Methods: Theoretical analysis, pedagogical experiment, anthropometry, statistical methods. Results: Height: the highest increase in that parameter was found in the Experimental Group of boys and the smallest one – in girls of the Control group. Body weight: boys from the EG showed the highest increase, while the lowest one was found in boys from CG. Chest circumference: the greatest increase was measured in CG of, while the smallest one in the EG of girls. In conclusion, we can underline that the changes in the anthropometric parameters are due both to the laws of biological developments of children at that age, as well as to the applied enriched educational content.

Livestock is a group of domesticated animal that is reared in an agricultural setting. It usually served as a source of income for most peoples in Malaysia. However, the productions of this livestock especially goats have been decreasing due to the occurrence of gastrointestinal helminths infection. The aim of this study was to identify the presence and species of gastrointestinal helminths from 120 fecal samples collected directly from the rectum of goats from a farm located in Kuantan, Pahang. Firstly, the physical observation was evaluated on all goats. Then, their fecal sample was examined within 96 hours using Formal-ether Sedimentation method for the morphological characteristics identification of gastrointestinal helminthic species under the microscope. This study has identified the majority of goats with a good physical condition, that they have no sign of blood loss and have appropriate body frame. However, the microscopic identification has revealed 89 from the total samples positive with gastrointestinal helminths species while 76 of the positive showed presence of mixed species. The species found were Haemonchus contortus, Trichostrongylus spp., Trichuris ovis, Oesophagostomum spp., Ostertagia spp., and Strongyloides papillosus. This high infection of gastrointestinal helminths observed in goats is related to an impaired immune system, poor farm management, and uncontrolled anthelmintic treatment. The presence of various species of gastrointestinal helminths within a goat is an important cause of morbidity and loss of production. Therefore, this study suggested the need for an effective system of management, diagnosis and appropriate treatment that can reduce the risk of infection and increase the productivity of the animals.

Crespo et al. (1999) was the first to identify the problem of turkey femoral fractures in breeding farms [3]. It was suggested that this type of failure was the result of fatigue under daily activities as opposed to acute trauma [1]. There are a number of factors that can lead to decreased bone integrity including ineffective bone mineralization, microcrack propagation and changes in collagen fibril orientation [1, 4, 5].

Sheep Production

Donald (1962) has recently pointed out the paucity of available data on production from British sheep, though some information is available for hill sheep (see for example Donald, 1958; Purser and Roberts, 1959; Purser and Young, 1959; Dalton, 1962). Most of these refer mainly to the Scottish Blackface and Welsh Mountain breeds. Hill sheep form approximately 40% of the national flock of over 11 million breeding ewes. Another 40% of ewes are found in crossbred flocks mainly kept on the lowlands; these produce fat lambs and hoggets with wool as a secondary product. Very little information has so far been published on these crossbred ewes, exceptions being work reported by Bywater (1945) and Rennie (1957). This is the first of three papers to be presented with the object of providing such information, and is based mainly on the work of Yalçin (1963). It is hoped that these papers will be of use on two counts:1. To provide a documentation of one specific cross, the Border Leicester × Cheviot ewe and her Suffolk-cross lambs under North of England grassland conditions.2. To analyse the usefulness of keeping production records within such flocks as aids to good commercial management, to culling and to selective breeding.In this paper the traits studied are body weight, fleece weight and litter size of the ewes, and the weights of the lambs between birth and slaughter or weaning. Estimates were obtained for the effects upon some of these traits of age and live-weight of ewe, and of sex, year and type of birth and rearing of the lambs. The usefulness of such correction factors is considered within recording schemes. In subsequent papers the effects on production of differences between crossbred ewes and between the rams used as fat lamb sires will be considered.
