It is the intermediate and definitive host of many parasites, especially endoparasites, such as trematodes, cestodes and nematodes (Bikhovskaya-Pavlovskaya and Kulakova,1987; Carney and Dick, 1999; Behrmann-Godel and Brinker, 2005; Wierzbicka et al., 2005; Kuchta et al., 2009). Information concerning the parasites of perch can be found in widely published literature (Rolbiecki, 2006; Halmetoja et al., 2000), but still little is known about aspects such as the age dynamics of infections with endoparasites. Parasites provide a great deal of biological information about their host, regarding migration, differences in diet, and food web structure (Williams et al., 1992; MacKenzie et al., 1995; Marcogliese et al., 2006). On the other hand, parasitism may influence the behaviour of fish (hosts), resulting in changes in their habitat and increasing vulnerability to predators (Seppälä et al., 2008). Infection with parasites increases the relative risk of mortality in the host (Behrmann-Godel and Brinker, 2005). In this paper we determined the occurrence of parasites in perch from Lake Góreckie, Wielkopolski National Park. Perch is common in water bodies and has a diverse diet, and for these reasons it is the definitive or intermediate host of many parasite species. Therefore, this fish species was selected for our study. The influence of age on the occurrence of parasites in perch has not yet been examined in detail.\u0000\u0000The aim of this study was to answer the following questions: • What parasites occur in perch in Lake Góreckie? • Which species of endoparasites are more frequently observed in perch in Lake Góreckie? • Is there a correlation between the occurrence of the endoparasite and the age of perch? \u0000\u0000","PeriodicalId":53138,"journal":{"name":"Roczniki Naukowe Polskiego Towarzystwa Zootechnicznego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84135364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Half of the population of each sex, i.e. 10 animals (active dogs), were either currently participating in dog frisbee competitions or had recently finished their sporting careers due to age. The other half (part) of the examined Border Collies, i.e. 10 females and 10 males, were animals that were not active in sports (non-active dogs). Most of the dogs came from Polish kennels but there were also Border Collies from other countries.\u0000The following measurements were taken: trunk length, height at withers, chest girth, fore limb (metacarpal) girth, thigh length, shank length, foot length and body weight. The collected results were processed statistically and indexes of trunk length, massiveness, eurysomia and boniness were calculated.\u0000It was found that Border Collie are characterized by some biometric traits (indexes) similar to Polish hunting dogs and Polish hounds and some of their indexes are also similar to the domestic breeds of Polish sheepdogs and Polish charts. Conducted biometric analysis showed only few, i.e. concerning height at withers of females and body weight of males statistically significant differences between examined groups of Border Collies. Consequently, there was no positive verification of the research hypothesis, which assumed that the value of traits and biometric indicators of Border Collie is different in jumping dogs in connection with their participation in various disciplines of dog competition. However, it can be assumed that for the needs of the developing sports cynology, there will be a need to select dogs with predispositions for athletic performance, and a useful tool to achieve this goal will be the analysis of biometric traits of dogs. The results of measurements collected in this study and the indices calculated on their basis also extend the biometric database of Border Collie dogs.\u0000\u0000","PeriodicalId":53138,"journal":{"name":"Roczniki Naukowe Polskiego Towarzystwa Zootechnicznego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85720553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was also focused on identification of potential differences in the mean values of the fat parameters and carcass weight between the forest and field ecotypes of roe deer. The medullary cavity area was measured using the DIRA 200 program. Metacarpal bone III and the phalanges of the 2nd and 3rd fingers were measured as well. The investigations involved 38 females of the European roe deer Capreolus capreolus aged 3-5 years.The investigations revealed a negative statistically significant correlation between the surface area of the medullary cavity in metacarpal bone III and the kidney fat index KFI (rs = -0.483; p<0.05) and the weight of the perirenal adipose tissue (rs = -0.362; p<0.05). No correlation was shown between the area of the medullary cavity of metacarpal bone III and the doe carcass weight (rs = 0.093; ns). The size of the medullary cavity is an anatomical parameter that is not susceptible to cyclical changes in environmental conditions. As shown in this study, it is independent of the body weight and determines the amount of bone marrow and, hence, the amount of accumulated fat reserves. We believe that, besides biometric measurements, the surface area of the medullary cavity can be a good parameter for assessment of the ontogenetic quality of roe deer and for comparison of populations.\u0000\u0000","PeriodicalId":53138,"journal":{"name":"Roczniki Naukowe Polskiego Towarzystwa Zootechnicznego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80518391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until now, the most popular fibres used in composites have been those obtained by chemical processes. Natural fibres are much less commonly used, but interest in them is growing due to the principles of eco-development, care for the environment, and their important fact that they are biodegradable. Sheep wool, due to its unique physicochemical properties, such as thermal and sound insulation and the ability to absorb and release moisture, can be used as a fibre in biodegradable composites. Biodegradable polymers are becoming increasingly popular as an alternative to plastics, which have a negative impact on the environment. Although the use of biodegradable polymers is limited by their poor mechanical and thermal properties, a filler in the form of sheep wool fibres increases the mechanical properties of the composite and reduces production costs, while maintaining its biodegradability. Mixed wool is treated as a waste product which is difficult to utilize in the textile industry, but innovative applications in agriculture and medicine provide the opportunity to make use of it. As a fibre with unique physicochemical properties, wool can be used as an element of biocomposites in line with the strategies of bioeconomy and sustainable development.\u0000\u0000","PeriodicalId":53138,"journal":{"name":"Roczniki Naukowe Polskiego Towarzystwa Zootechnicznego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84334536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main hormone produced by the hens’ adrenals is corticosterone, synthesized and secreted by stimulating the HPA axis during stress. Direct activation of adrenal activity is conditioned by ACTH, which binds to the melanocortin receptor cMC2 in adrenals. It stimulates the synthesis and release of corticosterone. One of the factors that stimulate the HPA axis activity is the starvation, to which the hen is very sensitive. The purpose of this study was to determine the ACTH receptor cMC2 expression in the hens’ adrenals during the short-term fasting and after restoring the proper level of nutrition (refeeding). The results of the experiment show that 24-hour of food deprivation is stressful for the hen, as indicated by increased concentrations of corticosterone in the adrenals and in blood plasma. Changes in cMC2R expression and level of corticosterone in the adrenals during fasting and refeeding indicate a rapid increase of HPA axis activity in response to differentiated levels of nutrition. The results of this experiment confirm the direct effect of ACTH on the avian adrenals in corticosterone release.\u0000\u0000","PeriodicalId":53138,"journal":{"name":"Roczniki Naukowe Polskiego Towarzystwa Zootechnicznego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75413470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
