Zhodnocení růstu a základních ukazatelů jatečné hodnoty jehňat kříženců plemen romney marsh a clun forest
Minářová, Tereza
The aim of this thesis was to evaluate the growth and basic indicators of carcass value of romney marsh lambs (RM) and crossbreeds of romney marsh and clun forest (CF x RM). The study was carried out in 2019 on the family organic farm in Budeč. The first part of this work is a literature summary that represents problematics of growth and carcass value of lambs. It also deals with the possible effects of various factors on the parameters of growth ability and carcass value of lambs. The next section presents characteristics of the farm and monitored breeds of sheep. The growth was evaluated on the 25 male lambs sample. Live weight was measured at birth, at 70 days, at 100 days and at 130 days. Based on these live weights average daily gain at each interval was calculated. Further, the effect of genotype and interaction of genotype and litter size on live weight and daily gain were evaluated. The genotype had no significant effect on any of the live weights. In terms of average daily gain, the genotype had a significant effect only at some intervals of lamb´s life. Higher live weight at 100 days of age (28.2 kg) and higher daily gain from birth to 100 days (234.9 g) were found out in RM lambs. The effect of the interaction of genotype and litter size was found for most of the monitored live weights and average daily gains. In RM lambs, higher live weight at 100 days (32.0 kg) and higher daily gain in the interval from birth to 100 days (268.4 g) were found in singles. But in CF x RM lambs, these results were higher for twins. For control slaughter 10 male lambs were slaughtered of which 5 of them were RM and 5 of them were CF x RM. As part of the assessment basic indicators of carcass value and the influence of genotype on these indicators, the live weight before slaughter, carcass weight, weight of skin, weight of selected internal organs and right leg weight were determined. Meatiness and fatness were also subjectively evaluated. Slightly better results were found in CF x RM male lambs. In terms of the influence of genotype on carcass value and weight and proportion of viscera, none of the results of the control slaughter were statistically significant.
Českomoravský belgický kůň a jeho využití v minulosti a současnosti
Bartoš, Michal
The bachelor thesis describes the history and breeding of the Czech-Moravian Belgian horse breed. Its development, current rearing and areas of its use. This breed is also referred to as the Belgian horse, or the Belgian draft horse is the most common breed of cold-blooded horses. Part of the bachelor thesis is an analysis of the frequency of use of stallions in insemination. Stallions in Tlumačov and Písek stud farms were monitored. Data collection took place in the case of Tlumačov between 2009 and 2020. Data for the years 2012 to 2019 were collected in the Písek. The percentage of conception of these stallions was evaluated. There were 11 stallions working in the stud farm in Písek, with which a total of 176 mares were inseminated. The average conception in this stud farm is 58.86 %. There were 9 stallions in Tlumačov, with which 200 mares were inseminated, with an average conception value of 68.90 %
Sledování reprodukce a přírůstků hmotnosti u výstavních holandských králíků
MASOPUSTOVÁ, Vladimíra
The diploma thesis deals with the monitoring of reproduction and weight gain in exhibition Dutch pet rabbits. The breed in which the work was monitored has stably 25 females and 8 - 10 males. During the breeding season, this breed base produces approximately 370 - 400 young rabbits. In the literary part of this work is described the history and origin of rabbit breeding in our country, the breed standard Dutch black, as well as general information about the sexual system, rabbit breeding and nutrition of these animals. The practical part includes monitoring, which deals with a given number of litters for the breeding period, in which natality and mortality, weight gains, the course of rearing and the drawing of the breed are monitored. In addition, behavior, pregnancy, childbirth and litter care are observed in females in breeding. At the end of the thesis, these findings are processed and the whole breeding is evaluated according to the obtained data.
Věková struktura populace plemenných hřebců plemen chovaných v ČR
PÍCHOVÁ, Vladimíra
work deals with the age structure of stallions of selected breeds, which they use for breeding. These are the Czech warmblood, the Old Kladruby horse, the Czech-Komoravian Belgian horse, the Welsh pony and cob breeds, and the Shetland pony. The aim was to explain the concepts associated with horse breeding and breeding activities of stallions. In the work itself, the age structure of stallions of individual breeds was compared, in the categories up to 8 years, 8-15 years, and in the category 16 years and more. The development of these age categories is monitored in 2005, 2010, 2015 and 2020. Furthermore, the mating activity of stallions was monitored according to age, number of matings and births of foals.
Porovnání metabolického profilu u ovcí v závislosti na plemenné příslušnosti a věku
MÍKOVÁ, Eliška
Comparison of blood metabolic profile at sheep was the aim of my Bachelor Work. The breed and age were influenting factors. Hematological, biochemical and mineral parameters were followed. I recieved and evaluated blood samples of 13 females, 1 male and 20 lambs during 2021 - 19th April, 3rd May, 29th June and 22nd October. Getting results were compared with figures from world literature. No significant differences in physiological parameters were found at lambs of Suffolk and Šumavka breed whereas some light differences were found in number of leucocytes, lymphocytes and granulocytes. The changes of metabolic profile depend on the age of animals. Higher values in haemoglobin were measured in the collection on 22 October, leucocytes and urea, and thus seasonal effects were evident.
Vyhodnocení produkčních vlastností ovcí plemene suffolk a charollais v ekologickém chovu
VOSTŘÁKOVÁ, Veronika
The aim of this diploma thesis is to evaluate production characteristics of two breeds of sheep: Suffolk and Charollais. Data for evaluation of characteristics were received from the performance control in years 2016 - 2019. This data were afterwards compared with the nationwide results. This thesis focuses mainly on fertility, fertilization, rearing, number of sheep in reproduction, intensity, evaluation of growth capacity of lambs after birth, death rate of lambs and the difference in number of sheep with single lambs, twins, triplets and quadruplets. In 2016, the average fertilization of the Suffolk breed was 94.1%. In 2016, the percentage of fertilization in the Charollais breed was 97.2%. In comparison with the national results, the average fertilization on the Bočan Farm is higher, in the Suffolk breed by 4.9%. The average fertility per ewed sheep from 2016 - 2019 in the Suffolk breed was 147.4%. The average fertility of the Charollais breed was 159.3% during the observed period. The average intensity in the Suffolk breed was 142.5%. The lowest intensity was in 2016 - 129.4%. The highest intensity of the Charollais breed was reached in 2017 - 164.6%. Another value observed was the weight of lambs after birth and at the 100th day of age. The average weight of Suffolk breed ewes after birth was 2,87 Kg, for rams it was 3,04 Kg. The average weight in the Czech Republic, during the measured period, was 3,1 Kg. The lowest weight of ewes at the 100th day was 28,40 Kg in 2016. The average weight of rams was 30,49 Kg. The lowest weight of Charollais breed ewes after birth was reached in 2019 with value of 2,89 Kg. The highest weight of rams was reached in 2018 with value of 3,27 Kg. The average weight after birth in the Czech Republic is 3,3 Kg. Another parameter monitored was the death of lambs. The most dead lambs in the Suffolk breed were in 2019 - 12 pieces, in the Charollais breed there were the most dead lambs in the year - 2018 - 25 pieces.
Analýza vybraných vlivů na mléčnou užitkovost a plodnost u stáda českého strakatého skotu
KROPÁČEK, Roman
The analysis of selected effects on milk yield and fertility in a herd of Czech spotted cattle deals with some effects observed on the basis of milk yield control data. The observed values are performance for standardized lactation, fat and protein content in milk, length of interval, service period and insemination interval. The age at first calving and its effect on milk yield as last factor. In period 2016 - 2018 are compared diary cows in their first three lactations. In the first part of the Bachelor thesis the history is processed and brief description of Czech spotted cattle. The following chapters deal with milk yield and fertility and selected factors mentioned above. The experimental part of the work presents the company where the observation was performed. The results are evaluated and presented into tables and graphs and then compared with the national results and according to the available literature.
Hereditary monogenic health disorders in canine breeds in relation to breeding
ORSÁKOVÁ, Kamila
This thesis deals with problematic of prevalence of single-gene disorders for various dog breeds. The goal was to discover the groups of dog breed with the highest prevalence of single-gene disorders and discover which of these disorders tends to affects most of the dog breeds. We have evaluated 23 closely related groups of dog breeds (Parkerová et al. 2017) with the appearance of some single-gene disorder as we predicted based on our analysis based on OMIA database dated to year 2018-2020. The analysis showed us that the Neuronal Ceroid Lipofuscinosis (NCL) and Progressive Rod-Cone Degeneration (PRCD) affecting most of the dog breeds. We also discovered that the genetically closely related dog breed group 20T, which contains 16 dog breeds, suffers from over 49 types of single-gene disorders. We also discovered that the Border Collie is the dog breed with the highest single-gene disorder prevalence in previously mentioned group 20T. This dog breed is affected by 9 disorders at least. In our analysis the dog breed Labrador Retriever and German Shepherd are suffering from most types of single-gene disorder (more than 15). These dog breeds are one of the most common dog breeds in Czech Republic. This finding supports the hypothesis that the popular dog breeds tends to have better mapped genome and are subjects of testing more often. This thesis provides the characteristic of selected dog breeds. The genetic specifications also contains the recommended breeding method parameters for the minimization of disorders in population.
Prevention of children risk bahaviours in interactions with dogs
NÁHLÍK, Jan
Dog attacks on children are a widespread problem, which can occur when parents fail to realise a potentially dangerous interaction between a dog and a child. The aim of the study was to evaluate dogs attacks to children in Czech households, the ability of parents to identify dangerous situations from several everyday child - dog interactions, determine whether the participants connected these situations to a particular breed of dog and whether participants intend to participate in the dog bite preventing program for them and their children. Data were presented via an online survey to parents of children no more than 6 years old. Data from 208 respondents were analysed using procedure GLIMMIX in SAS program, version 9.3 and Pearson's Chi-squared test in program "R". We recorded 19 dogs attacks on children and children always knew attacking dog. Parents were present and supervised 18 children when attacks happened. Three children had to receive medical help after being attacked by a dog and one developed a post-traumatic stress disorder - a phobia of dogs. Most participants would welcome educating programs about child - dog interactions, more often those who owned a dog (p < 0,05). The probability of risk assessment varied according to dog breed (p < 0.001) as well as to the depicted situation (p < 0,001). Results indicated that Labrador Retriever was considered the least likely of the three dogs to be involved in a dangerous dog - child interaction (with 49 % predicting a dangerous interaction), followed by Parson Russell Terrier (63.2 %) and American Pit Bull Terrier (65 %). Participants considered one particular dog-child interaction named 'touching a bowl' a dangerous interaction at a high rate (77.9 %) when compared with the other presented situations, which were assessed as dangerous at rates of 48.4 % to 56.5 %. The breed of dog seems to be an influential factor when assessing a potentially dangerous outcome from a dog - child interaction. Contrary to our hypothesis, interactions involving the small dog (Parson Russell Terrier) were rated more critically, similarly to those of the American Pit Bull Terrier. These results suggest that even popular family dog breeds, such as Labrador Retrievers, should be treated with more caution.
Breeding and morphological differences of domestic dog
Nový, Jakub ; Figura, Roman (advisor) ; Komárek, Stanislav (referee)
Dog (Canis lupus f. familiaris) is one of the oldest domesticated animals and he has been by our side for several thousand years. Although we know a lot of different domesticated animal breeds but by far it didn't reach such distinction in case of dog. In my work I'll be examinating domestication of this beast and its breeding. Also I'll be dealing with breeds of dogs and especially with morphological differences between them. Key words: Canis lupus familiaris, domestication, breedig, morphology, breed
