The use of otoliths for growth and population dynamics studies of Percidae and Cyprinidae in Most water reservoir
Tůmová, Eliška ; Frouzová, Jaroslava (advisor) ; Pivnička, Karel (referee)
This Master thesis compares growth of Percidae and Cyprinidae in flooded mining pit Most with water reservoir Vír, which is stable, fifty years old. Fish were cought using toils by workers from Hydrobiology institute, Academy of Sciences, Czech Republic, which are exploring fish stock. Otoliths, scales, and operculas from both families, Cyrinidae and Percidae, were removed from fish for age determination and growth back-calculation in individual years. Due to surplus of nutrients and food in flooding mining pit is assumed a huge growth difference in the first two years of life. The aim of this thesis is not only to describe the difference in the expected growth of individual species, but also to estimate its causes. At the same time will be in a very contrasting conditions compared different methods of age determination. Key words: otolith, fish age, fish population, fish growth, water reservoir, flooded mining pit, growth back-calculations

Sledování růstu teplokrevných hříbat
Scheibingerová, Michaela
This diploma thesis focuses on monitoring the growth of warmblood foals. The aim was to evaluate growth allometry, hippometric indexes and correlation dependence between individual body measurements; furthermore, to statistically assess the growth of foals in relation to certain factors (sexual dimorphism, breeder, year of birth, birth order, sire) and to compare the values obtained with growth standards and growth ranges for warmblood horses. Three breeding farms from the South Moravian region were included in the study. The measuring of the foals was carried out between 2013 and 2016, from birth to three years of age, once per month using measuring devices (a measuring stick and tape). The measurements taken were: stick height at withers, tape height at withers, chest circumference, body length and cannon bone circumference. The results indicated that colts are much more susceptible than fillies to the negative effects of external factors and have more difficulty withstanding them. However, the growth rate of colts was higher for all the dimensions assessed. Throughout the monitoring period, fillies exhibited a higher trunk size index, which is a result of the anticipated development of the foetus in adulthood. Due to the demonstrably heavier frame of colts, the cannon bone load index was found to be higher in fillies. The highest growth capability was achieved at the Velké Němčice breeding farm, where foals appear to be provided with the optimal conditions for growth and development. Furthermore, it was established that foals born as the 4th or 5th foal exhibit the highest growth rate. This result can be attributed to the fact that mares (dams) have reached physical maturity and are capable of meeting the needs of foals. Conversely, the weakest growth was achieved with foals born as the 1st, 3rd or 6th foal. After assessing the values obtained against the growth standards, we decided to retain the existing ones with an emphasis on breeders regularly monitoring the growth and development of foals.

Analýza růstové schopnosti krůt ve vybraném podniku
JANDOVÁ, Lucie
The aim of the thesis was to evaluate the feeding parameters of hybrid B.U.T. 6 at selected farm. Six batches of tom turkeys were evaluated in this study. The growth intensity analysis was performed based on weekly weighing. The average live weight was 21.83 kg at the age of 21 weeks. The highest value was in the 3rd batch (22.18 kg) and the lowest value was in the 2nd and the 6th batch (21.62 kg). In comparison with the "Management guide", the differences in average weight from the 5th week of age to the end of fattening were evaluated as statistically significant. The average feed conversion ratio was registered 2.73 kg. The highest feed conversion was in the 1st batch (2.82 kg) and the lowest was in the 5th batch (2.62 kg). The average inflection point was reached in the 14th week (12.1 kg). First the inflection point was achieved in the 1st and 2nd batch (13.6 weeks; 11.7 kg and 13.7 weeks; 11.4 kg) and at the latest in the 4th batch (15.5 weeks; 13.6 kg). The average maximum daily gain was reached 203.1 g (13.6 weeks). The highest was in the 3rd batch (204.9 g; 13.6 weeks) and the lowest was in the 4th batch (195.3 g; 14.3 weeks). The average mortality rate was found 6.39%. The highest mortality rate was in the 6th batch (8.44%; 858 pcs) and the lowest was in the 4th batch (4.50%; 457 pcs).

Ecological and phylogenetic effects determining variation of growth patterns in amniotes
Stanková, Veronika ; Frýdlová, Petra (advisor) ; Vohralík, Vladimír (referee)
Growth is a process during which organs or the whole body enlarges. It can be modeled by using growth models and curves. The work is mainly focused on the explanation of two types of growth - the determinate growth, which is finished after the reaching of the sexual maturity, and the indeterminate growth which on the other side continues even after the reproduction or after the reaching of the sexual maturity. In the literature there is generally stated that birds and mammals are characterized by the determinate growth, amphibians and reptiles have the indeterminate growth. The aim of this work was to analyze the current available literature relevant to the growth and to evaluate the above mentioned statements about the growth of the vertebrates. The ecological and the phylogenetic effects influencing the growth, the physiological regulation and the mechanism of the growth are summarized in this work. Powered by TCPDF (www.tcpdf.org)

Sledování růstu huculských hříbat
Karbusická, Alžběta
The thesis explores the current state of Hucul foals' development by measuring in two largest breeding farms in the Czech Republic. Each of the farms is located in different climate conditions and the way of breeding differs as well. Further aim was also to carry out a literature review on the topic of growth and development of foals including issues of creating growth curves and their usage. Measurements were carried out monthly from the spring of 2013 to the spring of 2015. A total of 23 foals were measured using laser measure and the only measured unit was the height at the withers. The work compares the effects of different breeding sites, difference in gender and in the fathers' lineage. The assessed lineages were Goral, Gurgul and Ousor. The curves confirmed the influence of breeding sites: foals from lowland areas grew more significantly. This thesis has no proven the influence of gender but many authors confirm this effect. The lineages are slightly different, however for better judgment more foals would need to be measured. The creation of growth curves for practice is not yet possible.

The Growth Warmblood Stallions During the Rearing
HRDINOVÁ, Lenka
The purpose of this thesis was to examine the growth and the growth curve of the Czech warmblooded horse stallions during rearing. Background materials were obtained based on its investigation of an examination horse rearing stable Czech warmblooded in Nový Dvůr (part of Municipal's stables in Pisek, sp). Stallions were measured in the years 2009 - 2010 in the age of 7 - 32 months. During this time it was measured 13 physical proportions, including four basic proportions ? height at withers (KVH) and height at withers measured by a tape (KVP), girth of a chest (OH) and girt of a shin (OHol). The growth curve and the behaviour of growth have been ascertained of the particular measurements. Then it was compared with literature. The greatest differences at results were observed in comparison with growth standards for height of withers. It was found that most of the measured stallions is classed in a growth zone + 1 (90.6% of cases). The remaining 9.4% of cases were included in the range + 2. The problem is also in the way, of definitiv of current standard, the current standard is determinated by one specific number (average value) and not spread within a certain range. The direct relationship with KVH also increased height at withers measured by tape. Based on the results we can conclude that the growth curve of the Czech warm-blooded stallions have changed and it should speculate about updating and modification of the standard for dispersion zone.
