Hoof disease in dairy cows
NOVOTNÁ, Michaela
The bachelor's thesis is focused on a globally problematic topic, which is hoof disease in dairy cows. The theoretical part discusses the anatomy and physiology of the thoracic and pelvic limbs, as well as the influences that affect the structure and diseases of the hoof. Infectious and non-infectious hoof diseases and prevention are also written in this chapter. In the practical part, the number of sick dairy cows and types of hoof diseases were monitored in the company AGRA Březnice a.s. 804 cows were monitoredover a period of three years, from January 2018 to December 2020. During this observation, it was found that dermatitis and ulcer diseases of the hoofs are the most common in breeding. Hoof disease affects around 50 % of dairy cows in all lactations. In sick cows, milk yield is reduced.

Hoof disease is one of the most common health disorders of high-producing dairy cows and limits the performance and health status of animals kept in stables. The aim of this study was to evaluate the occurrence of hoof disease and its effect on the milk yield of cows in a specific dairy farm. The work evaluated the effect of the occurrence of dermatitis digitalis (DD) and specific-traumatic inflammation of the hoof (ZŠP) on parameters of milk performance (daily milk yield, fat content, protein content and number of somatic cells in milk) and on the insemination index in the herd of Holstein dairy cows in years 2021 and 2022. The data set from 1,498 dairy cows was used for the evaluation, when 15,245 performance control records were processed. First, the average values of milk yield indicators were compared one month before the diagnosis of the disease and one month after the diagnosis of the disease. In this case, a statistically significant difference was demonstrated only in the number of somatic cells (PSB) in DD, when this indicator rose from the original 275 thousand to 487 thousand somatic cells. Furthermore, indicators of milk yield were evaluated in the month after the finding according to the stage of lactation. Here, a statistically significant difference was recorded in the second stage of lactation (from the 41st to the 100th day) in the fat content of cows with ZŠP, when the fat content in cows without findings was 3.59 % and in cows with ZŠP it dropped to 3.29 %. Furthermore, a statistically significant difference was recorded in the fourth stage of lactation (day 201-304 of lactation) in protein content and number of somatic cells. When the highest protein content was recorded in DD - 3.73 %, in cows without hoof disease the protein content was 3.69 % and in cows with ZŠP the protein content dropped to 3.58 %. The number of somatic cells in cows in this stage of lactation was 363 thousand in cows without hoof disease. and for cows with DD it rose to 599 thousand. Furthermore, the effect of hoof disease on the insemination index was assessed. For this indicator, no difference was found between cows without disease and those with hoof disease. However, a clear influence of the insemination technician who performed the insemination was found. When assessing the effect of the disease according to its species, an average insemination index was found for cows with DD of 2.10 and for cows with ZŠP of 2.31. However, the difference was evident only for one insemination technician.

The health status of dairy cows has a direct impact on milk production and the related breeding economy. Any disruption of the health of the dairy cows reduces milk yield and negative affects the economy of breeding. Maintaining good limb health in dairy cows i sone of the most important tasks of production and preventive veterinary medicine. The bachelor's thesis is focused on the occurence of hoof diseases on three dairy farms breeding Holstein cattle. Monitoring took place in the years 2018 - 2020. A total of 2 163 dairy cows were included in the follow-upm divided into 5 groups according to the order of lactation. The most common diseases were specific-traumatic inflammations of the hoof joint, where their incidence ranged from 7,9 % to 14,8 %. Another disease assessed was digital dermatitis, which occured from 7,28 % to 14,24 % during the monitored years. The last disease studied was necrobacillosis. This occured on farms ranging from 1,22 % to 4,74 %. The work also decribes the characteristics of the Holstein cattle, the anatomy of the hoof, treatment and prevention of individual diseases, as well as the factors influencing the development of hoof disease.

Výskyt onemocnění končetin u dojnic ve vztahu k jejich výživě, resp. složení mléka
Ticháček, Martin
The aim of this diploma thesis was to observe the occurrence of lameness and health condition of hoofs in the Klučov - Lhota farm. Czech Fleckvieh cows with breeding affiliation C100 were assessed. Diagnoses and hoof pathological conditions, feed ration compositions and composition of milk obtained from performance control were recorded. Results were compared between limping and healthy cow groups. The results of limping cows according to individual diagnoses and pathological processes were also evaluated. The results show that impaired locomotion scores and individual pathological conditions had a negative effect on milk production. The results are different for individual milk components. However, there weren't statistically significant differences between groups for most of evaluated parameters.

Kulhání-Limitující faktor reprodukce skotu
VRABČEKOVÁ, Monika
One of the basic conditions for achieving a positive production and meeting economic objectives in cattle breeding is their high and regular reproductive performance. Amongst the most significant factors influencing cattle fertility is the health state of heifers. To breed cattle successfully, it is essential to ensure that their feet are in a good condition, in particular hoofs. Diseased feet lead to the reduction of cattle performance and affect their welfare which results in a negative impact on cattle fertility. This thesis is concerned with the influence of cattle lameness on reproductive indicators of cows. For the purpose of the research, a group of cows from ZD Pluhuv Zdar including 843 dairy cows of the Holstein breed and Czech Simmental breed was studied. Equally, all cows originated from two different types of stabling. The following information were checked about each cow: the identification number, stabling number, breed, age, date of calving, order of lactation, performance, interim period, service period, insemination interval, insemination index and any relevant hoof problems. The impact of hoof problems on reproductive indicators that depended on the order of lactation and breed were analysed in the program Statistica using two-factor anova. It was observed that there existed a significant influence of hoof disease on each reproduction indicator. Dairy cows on the 3rd and higher level of lactation showed an evident difference in the length of the interim period. It was found that healthy dairy cows without any hoof disease had on average 385 day long interim period, whereas dairy cows with hoof problems had 398 day long interim period. It is apparent that the interim period was lengthened by 13 days in dairy cows with lameness. In addition, the values for service period and insemination index increased in the group with cattle lameness (by 17 days and the value of 3.17). In the case of insemination interval values, the difference between healthy and diseased cows was the least apparent. Furthermore, it was proven that the combination of infectious and non-infectious diseases have the greatest impact on reproduction indicators that seem to increase their value as a result. This causes a great deal of stress to an organism of an animal. When comparing reproduction indicators between breeds, it was noticeable that there was an influence on the cross breeding and how strained the Holstein breed was. The average length of interim period was 8 days longer in the Holstein breed group than Czech Simmental cattle. Furthermore, the length of the service period was 5 days longer in the Holstein cattle group. From the data, it can be concluded that any hoof disease in herds should not be neglected and stock breeders should pay increased attention to hoof problems since it could pose a risk on the whole stock breeding economics. A stock breeder should focus on the regular and careful trimming, washing and treatment of hoofs. In addition, attention should be paid to stabling and how comfortable it is for dairy cows, as well as the quality and complexity of feeding portions that are served.
