Digitálna dermatitída a jej dopad na produkčné a ekonomické ukazatele
Bončová, Barbora
Hoof health problems are a concern in all dairy farms worldwide, impacting the well-being of cows and productivity, which directly affects the farm’s economy. One of the most widespread diseases is digital dermatitis (DD). The subject of this work was to evaluate the incidence of digital dermatitis based on parity and lactation phase on dairy farm with approximately 700 Holstein cows. An experiment was conducted to determine the correlation between disease presence and milk yield. ANOVA with repeated measures was used as statistical analysis, with the dependant variable being average daily milk yield. Dairy cows were divided into four groups based on parity and lactation phase. Furthermore, the course of lactation was examined during the period of nine weeks with hooves treated in fifth week. The cost of digital dermatitis was calculated per sick cow and for the entire farm using multiple models for comparison. Results showed that primiparous cows had the highest incidence of the disease, and numbers decreased with increasing parity. The incidence of digital dermatitis was approximately 12% in the observed group. A statistical dependence was confirmed in only one group, specifically in dairy cows during the second and third lactation in the second phase. After treatment, a few weeks of reduced milk production were noted, while cows with DD had higher milk yield during the study period. This suggests that high-productive cows have a higher predisposition to DD. The calculated costs per cow ranged from 1,488.66 to 2,234.51 CZK across different models, with total costs for the company ranging from 113,784.67 to 193,545.32 CZK per year.

Příprava datasetů termosnímků paznehtů skotu vhodných pro trénování CNN
ZAHAJSKÝ, Radek
Bachelors work dealing with dataset preparation for CNN training, computer vision and deep neural network learning. Other important aspects are the use of this technology, the different applications, formats and color spaces. The practical part describes the process of image annotation in CVAT software. The work involves individual extraction of information on each subject and comparison of applications and formats. The main result of the work is the creation of a high quality dataset for the identification of dairy cow hooves.

Nepravidelnosti postojů u hříbat po narození a možnosti jejich korekce
SOUKUPOVÁ, Dominika
The diploma thesis was targeted towards on the irregularities of attitudes in foals after birth and the possibility of their correction. A total of 8 foals were monitored, of that 6 were geldings and 2 were mares, of various breeds and ages and from various owners within the Czech Republic.The initial, ongoing and final condition of the foals' hooves was recorded using photographs. The angle of the hoof, the angle of the anterior wall of the hoof and the cleft joint, the angle in the carpal/ankle joint and, in several cases, the angle in the knee joint were measured. The course of orthopedic corrections was also described for all foals.

Využití termokamery při monitoringu onemocnění paznehtů
DUDÁK, Pavel
The diploma thesis is focused on the use of modern technologies in limb diseases in herds of high-yielding dairy cows. The main goal of the diploma thesis is to verify the reliability of hoof disease detection in dairy cows using a thermal camera. By early detection of a change in the health of the hoof, it is possible to start treatment immediately. This reduces costs to treat and reduce milk production losses.

Ošetření kopyt v závislosti na využití koní
SOUKUPOVÁ, Dominika
The bachelor thesis was targeted towards the elements affecting the choice of horse hoof care. A total of 60 horses were monitored, of that 38 were geldings and 22 were mares, of various breeds and ages and from various owners within the Czech Republic. A questionnaire was used to gather information about the horses including their breed, age, type of stabling, current use and methods of hoof care based on their past and future. With this monitoring it was discovered when the horse can have only corrective hoof care versus when the horse needed to be shod on front legs or all four legs.
