Quality indicators of roe deer (Capreolus capreolus L.) venison from two different Czech regions

This study focused on differences in the monitored quality indicators of roe deer venison depending on the region of the Czech Republic where roe deer are hunted. Quality of roe deer venison was evaluated based on pH values, colour (CIEL*a*b* system) and chemical composition (content of haem pigments, dry matter, pure protein, collagen and fat). Samples of muscle from the leg (m. gluteus medius) were taken from 22 female roe deer (Capreolus capreolus L.) from two hunting regions (Liberec and South Moravia) in the Czech Republic. In roe deer from Liberec, higher pH value (5.65, P < 0.001) was found; muscles were darker (L* = 36.03), contained higher redness (a* = 14.41, P < 0.001) and yellowness values (b* = 12.10) and higher chroma (C* = 18.86). In roe deer from South Moravia, higher (P < 0.05) hue (h°) values, and higher level of haem pigments (2.45 mg·g-1) were found. Muscles from roe deer from South Moravia contained higher amounts of dry matter (29.52%, P < 0.001), pure protein (23.84%, P < 0.001) and total collagen (0.86%), and lower amounts of intramuscular fat (0.48%). These results may provide an important source of information for consumers of roe deer meat because several differences in the quality (chemical composition) of muscles from South Moravian region and Liberec region were found. Presumably, the differences between muscles from animals living in two different Czech regions were due to the diet, form of land use (more agricultural land in Southern Moravia, and forests and mountains in Liberec) and climatic conditions (Liberec lies in the northern part of the Czech Republic). It is the first study of this topic in the Czech Republic.

The objective of this research was to determine the efficiency of different types of protective barriers and how they protect against fraying damage in extensive fruit tree orchards. Orchards in open agricultural land are the target of fraying damage caused by roe deer (Capreolus capreolus L.). We assessed the effectiveness of four protective barriers: a rabbit-proof fence, a standard plastic tube commonly used in forestry, and an innovative plastic tube—variants with and without an additional rendering fat application. The study was situated in three extensive orchards in the southeastern part of Moravia in the Czech Republic. We analyzed the ratio of damaged trees, stem circumference damage, the length and height of damage on tree stems, the time periods with the most observed damage, and finally, the economic efficiency of each studied barrier. Most of the damage was observed in April and July. The most effective protective barrier was the innovative tube with rendering fat application (up to 100%) followed closely by the innovative tube without rendering fat application (95%). The standard plastic tube had an effectiveness of 49%, while the rabbit-proof fence was the least effective at 25%. In terms of the mean damage-lengths on tree stems, we found no significant differences between the rabbit-proof fence and the standard plastic tubes (21–22 cm). The usage of the innovative plastic tube without rendering fat reduced the average damage-length by half (10 cm) as compared to standard types (rabbit-proof fence, standard tube) of protection. The damage-heights on tree stems showed no significant differences among all variants (53–58 cm from the ground). Our analysis of economic parameters showed that rabbit-proof fencing had the worst cost efficiency, while the innovative tubes without rendering fat, had the best cost efficiency. We recommend starting the installation of protective barriers on trees in March, since we recorded relatively high activity of male roe deer in the following months.

South Moravia

To analyse the potential changes in soil characteristics and associated impacts on the land price, the region of South Moravia was selected, strongly threatened by erosion and by claiming the most valuable land in suburban territories due to industrial and housing expansion. For the detailed analysis of the impacts of erosion and land appropriation in the region of South Moravia, the model territories of Brno surroundings with the municipality of Dolní Heršpice and Hustopeče surroundings with the municipality of Starovice were selected. The price of land degraded by potential erosion in the South Moravian region fluctuates between 88 and 2 400 EUR/ha. In the past 180 years, 148 ha of agricultural land in the total value of 822 815 EUR have been used for construction in the location under study in Dolní Heršpice. Further growth of the municipality should involve additional appropriation of agricultural land in the value of 411 000 EUR. In the studied land block of 100.5 ha, located in the Starovice municipality area, water erosion caused degradation in the total value of 92 000 EUR in the period 1978–2013. Extensive losses of fertile agricultural land are to be expected in the future. Their main causes are continuing land appropriation and degradation processes – soil erosion.

This article analyses data on the reported and captured populations of red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon) in the Czech Republic during the years 2002–2006. Breeding and hunting plans collected by the State Hunting Authority have been summarized. The analyzed game population size (APS) for each individual territory, using the reverse calculation method, was compared to the counted population size (CPS) of each species. Next, the ratios between the specified population size (SPS) and the CPS were compared; and also the ratios of CPS and actual hunting bag were compared for individual years in the specified periods. Many errors in hunting management policy were found in all analyses regarding red deer. In many cases the APS, using the reverse calculation method, was several-times higher than the CPS. Also a large difference between SPS and CPS was very common. Similar results were also found in the analyses of fallow deer and mouflon populations, where the management policy was very similar to that of red deer. Evaluation of the roe deer management policy showed better results. Despite the fact that the APS was higher than the CPS, it was never several-times higher. Even in SPS and CPS ratios no extreme outcomes were found. From the official processed data it is evident that hunting association plans for game breeding and hunting indicate many significant problems, where the smallest problem is with roe deer and the biggest problem is with red deer.

The present study aimed at the aetiological diagnosis of skin tumours of roe deer (Capreolus capreolus) in the Czech Republic. A total of 33 roe deer specimens showing skin masses were sampled for histopathology, virus detection and identification using polymerase chain reaction (PCR) and deoxyribonucleic acid sequence (DNA) analysis, and to investigate fibropapilloma-associated levels of metallothionein, zinc and oxidative stress in 2012 and 2013. Ticks (Ixodes ricinus) and deer keds (Lipoptena cervi) were also collected and pooled from sampled game specimens. Ticks found on dogs in hunting grounds under study were pooled into another sample. Skin tumours, ranging from 2 to 10 per inspected specimen and 2 to 5 cm in size, were classified as fibropapillomas by histopathology. All 33 viral-infection-suspected skin samples from roe deer in South Moravia and South Bohemia were PCR positive. The nucleotide sequences of PCR products were 100% homologous to the Western roe deer papillomavirus 1 isolate CcPV-1. Ticks and deer keds from positive roe deer and ticks from dogs were PCR and DNA sequence positive for the roe deer papillomavirus. Viral DNA was also demonstrated in one blood sample from a roe deer female. Differences in metallothionein, zinc, taurine and electrochemical index among samples from lesions and normal skin of affected roe deer and negative controls from papillomavirus-non-infected animals were non-significant. While we have demonstrated circulation of specific roe deer papillomavirus in the Czech Republic that results in multiple fibropapillomatous skin tumours, many ecological and epidemiological issues of this wildlife disease still remain unanswered.

SummaryOnly a few studies have assessed the predation risk on artificially marked nests, or have examined ways of marking nests to avoid destruction by machinery. Until now, however, neither type of study has directly addressed this apparent trade-off experimentally. The impact of marking the nests of Northern Lapwing Vanellus vanellus with thin 2 m-long conspicuous bamboo poles with the top end highlighted with reflective red or orange spray has been tested for three years in two breeding areas of waders in the Czech Republic. A total of 52 pairs of nests on agricultural land, with each pair consisting of one marked nest and one unmarked reference counterpart nest, were monitored for 2004 nest-days until hatching, agricultural operations or failure. The results proved that marking itself does not result in increased nest predation. The nests found in the early incubation stage were under higher threat of depredation, irrespective of the presence of marking. Our results show that it is possible to find a finely-tuned trade-off in nest marking of ground-nesting birds between risk of damage by agricultural machinery and risk of increased nest predation. Our positive experience with Northern Lapwing, and episodically with three other wader species in the Czech Republic, suggests that this direct nest protection could be used effectively for a wider variety of ground-nesting birds.

South Moravia

The concept of Green Infrastructure (GI) is still relatively new in the Czech Republic. When looking at the definition of GI, one can recognise a relationship with the Czech Territorial System of Ecological Stability (TSES), which is defined as “an interconnected system of natural as well as modified semi-natural ecosystems keeping the natural balance”. TSES is a designed system and is an integral part of territorial plans. This article focuses on TSES and its relationship to GI, how it is implemented in a Czech case study representing intensively used agricultural region in South Moravia, what the main obstacles are to its implementation and how TSES can contribute to the connectivity of the landscape. Our results show that nearly two thirds of the planned TSES in the case study area already exist to some degree. There is a difference between the number and the area of existing TSES elements: the area of existing elements shows higher relative values than the number. This is mainly due to bio-centres that exist in large forest complexes and their pre-set minimal parameters. Creation of TSES elements increases connectivity of GI, especially those characterised as core areas and bridges

It was found that the inclusion of water enriched with molecular hydrogen into the diet of a long-tailed chinchilla changed the fur quality indicators. In animals of the experimental group, the guard and downy hairs were thinner than in the control group. The length of downy hair in the experimental group was higher, the number of hairs in the follicle in the chinchillas of the experimental group was greater than in the control group, besides, the hair was stronger and softer. The animals of the experimental group showed less tendency to gnaw out fur. When considering the data on the chemical composition, it was found that in the dry matter of the hair of the animals of the experimental group, there were less organic substances, and there were more minerals in comparison with the animals of the control group.
