Claw horn lesions are the most common cause of lameness in dairy cows and the development of lesions is related to the days in lactation. The lameness caused by this lesions is influenced by different factors (Offer et al., 2000). The objective of this experiment was to study the relationship of severity of lameness and severity of scoring for hoof horn lesions.

The goal of the work was to discover the influence of conformation traits evaluated by the Fleckscore system on the length of productive life of Slovak Simmental dairy cows. Evaluation of body conformation traits according to the Fleckscore system was performed on 3 452 cows. The relationship of individual traits to longevity was analysed using the Weibull proportional hazard model. The results confirmed that smaller and longer cows, which were well muscular and with a deeper body, had a lower risk of early culling than cows in the reference group. Hock angularity, pastern and hoof height scored with low or high marks were associated with an early culling of cows. In terms of the length of productive life, a slightly more elastic pattern is required. Cows with a deeper udder and a stronger and tighter fore udder attachment, which were also average in notching and height central ligament and centrally placed teats, reached a longer productive life.

The objective of this text is to present a reflection on the link between local initiatives to combat food insecurity and actions adapting to climate change. To this end, two case studies of ongoing experiments in the Canadian province of Quebec will be presented and compared. While these two cases are very different in terms of location, production and people involved, they share the objective of bringing fresh and healthy food, produced locally, to the population of their territory and of rethinking the relationship of the community to nature through food production. Despite their significant differences, each of these two cases features actions for responding to problems that have a common cause: an agro-industrial food system that, by decoupling the locations of production and consumption, in order to maximize the economic profitability of the capital invested, has compromised both the health of citizens and the ecological balance.

The decrease in fertility of highly productive dairy cows associated with postpartum ovarian depression is becoming one of the significant problems of modern dairy cattle breeding. The aim of this study was to identify and assess the state of protein, carbohydrate and lipid metabolism in Holstein-Friesian cows in the dynamics of postpartum period with the restoration and depression of ovarian ovulatory function against the background of their adequate feeding. The experiment included 16 fresh cows with an average annual dairy productivity of 9.5 ths kg. The blood for the study was obtained from the caudal vein on the 6th, 12th, 40th and 68th days after calving. Blood serum content of total protein and its fractions, urea, creatinine, total lipids, cholesterol, triglycerides and glucose was determined. The state of genitals was evaluated by transrectal palpation and ultrasound scanning, as well as by blood concentration of progesterone and estradiol. It has been shown that the formation of postpartum ovarian dysfunction in cows occurs against the background of low blood content of glucose, globulin protein fractions and increased creatinine content. The threshold serum concentration of glucose during the first two weeks after calving, at which ovarian dysfunction and a decrease in animal fertility should be predicted, is less than 2,2 mmol/L. There was expressed a judgment on the appropriateness of further researches to identify the relationship of the metabolic status of animals with the typological features of their higher nervous activity.

Abstract Despite the interest that sociologists, especially in the English-speaking world, show in animals and human-animal relations, we know little about the place that animals actually have in work. The social sciences still see work as a distinctive feature of humans. Based on the hypothesis that animals are actors involved in the process of work, and not simply objects, the relationship of a herd of 60 cows was studied (a) with their farmer, (b) among themselves, and (c) with a milking robot. Our findings show that cows do collaborate in the farmer’s work, and our results raise the question: can cows’ collaboration in work be considered work?
