BackgroundTie-stall housing of dairy cows is used extensively worldwide, despite of the welfare concerns regarding the restriction of voluntary movement and limitation of expression of the cows’ natural behaviour. The aim of this study was to compare the welfare quality of dairy cows kept in two types of tie-stall housing systems: with regular outdoor exercise and without access to exercise. In addition, the study investigated the relationship between different welfare measures of dairy cows kept in tie-stalls.Methods3,192 lactating cows were assessed using the Welfare Quality® assessment protocol for cattle in 80 commercial dairy farms, half of the farms providing outdoor access for the animals to exercise. The descriptive statistical indicators were determined for the assessed measures and for the welfare criteria and principle scores. The data obtained in the two housing types were compared and the correlation coefficients were calculated between the different welfare measures.ResultsThe significant differences found between the two housing systems for the majority of the animal based measures indicate the positive effect of exercise on the welfare of tethered cows. Many of the animal welfare parameters correlated with each other. For the farms allowing the cows’ turnout in a paddock, pasture or both, the mean scores for the welfare criteria and principles were higher than for the farms with permanent tethering of the cows, except the criteria absence of prolonged hunger and expression of social behaviours. The lowest scores were obtained for the criterion positive emotional state, in both housing systems. With regard to the overall classification, none of the farms were considered excellent. In the not classified category were only farms with all-year-round tethering of the animals and in the enhanced category only farms where the cows had outdoor access.ConclusionsThe welfare quality of the investigated dairy cows was significantly better in the tie-stall farms which allow exercise for cows (paddocks, pasture or both) than in those which do not. In the light of our results we consider that dairy cattle welfare is not necessarily poor in tie-stall housing systems, its quality depending on the management practices.

The aim of this study was to assess the effect of the housing systems (loose vs tiestall) on the welfare of dairy cows and to test the hypothesis that dairy cows in loose housing systems have a better welfare quality than those kept in tie-stalls. Sixty commercial dairy farms (30 with loose and 30 with tie-stall housing system) were selected for evaluation, using mainly animal-based measures, as the applied Welfare Quality ® protocol allows it. A total number of 2624 milking cows were assessed in the winter period. There were significant differences between the two housing systems for the majority of the parameters within the four welfare principles. Significant differences were also found in terms of the mean scores of the welfare criteria and principles, with the majority pointing out the loose system as better. Based on the scores of the four principles, most of the farms with loose housing were classified as enhanced, while the majority of the tie-stall farms were acceptable. The results show that the welfare quality of dairy cows is greatly influenced by the housing system, and that the loose system is more advantageous when it comes to the feeding, housing and behaviour of the dairy cow.

This paper investigates the effect of different housing conditions on the welfare quality of breeding horses. Using a welfare protocol that included health and behavioral parameters, 330 stallions (kept in tie-stall housing) and 365 broodmares (kept in extensive, mostly free housing) were assessed. The horses were categorized into four welfare categories (“not classified”, “acceptable”, “enhanced” and “excellent”), according to an individual welfare score calculated for each horse. The prevalence of stallions with dyspnea, tendon and joint swellings, abnormal gait and abnormal hoof horn quality was significantly (p < 0.05) higher than that of the broodmares. No significant difference (p > 0.05) was found in the human-related behavioral response of the two categories of breeding horses. The median individual welfare scores were significantly higher (p < 0.05) in the broodmares than in the breeding stallions. The mares had “enhanced” and “excellent” welfare, while the stallions had “acceptable” and “enhanced” welfare. The results revealed differences in the horses’ welfare quality for the different housing conditions. Accordingly, it can be concluded that positive changes in housing management, such as free housing with the use of boxes, could improve the welfare quality of breeding stallions.

The perceived level of risk associated with a food product can influence purchase and consumption decisions. Thus, current trends in food safety address an issue of general interest—the identification of healthy and economical alternatives to synthetic antioxidants that may have harmful effects on human health. Still, the processors’ target is to increase the shelf life of food products using preserving substances. Natural antioxidants can be extracted and used in the food industry from different plants, such as blueberry, broccoli, chokeberry, cinnamon, ginger, olives, oregano, etc. The identification of the main natural antioxidant types that have been used in the food industry is very important in order to provide a comprehensive analysis of the researched topic. In this regard, the aim of this paper was to illustrate the positive aspects of using natural antioxidants with preservative roles in meat products, while, at the same time, highlighting the potential risks induced by these compounds. All of those aspects are correlated with the impact of sensorial attributes and the improvement of the nutritional value of meat products.

The importance of a good human-horse relationship in every equestrian discipline is recognized by the specialists all over the world. The aim of the study was to comparatively assess the behavioural response towards humans in different horse categories, in two seasons. The human-animal relationship was investigated during a year, in two different seasons in working horses (171 in the winter, 168 in the summer), stallions (62 in the winter, 66 in the summer) and broodmares and young horses (137 in the winter, 146 in the summer). Using specific methods, the general attitude of the horses was evaluated (apathetic or alert) and their reactions (aggressiveness, fear/avoidance, indifference, friendliness) to the: (1) assessors' approach (2) walking besides and (3) the attempt of touching the animal. The data were analyzed using the SPSS statistical software. The value of minimal significance was considered at P < 0.05. The proportion of the apathetic horses recorded in this study varied from 0% to 3.23% depending on the assessed category and season, without statistically significant differences (P > 0.05). For the behavioural responses (aggressiveness, fear, indifference or friendly response), statistically significant differences (P < 0.05) were found among the assessed horse categories. The season had no significant influence on the variability of responses in the behavioural tests in none of the horse categories. The results indicate an inadequate human-animal relationship in all the studied horse categories, with negative implications on the welfare of the animals. This problem has low remedial possibilities, because it needs human mentality change of those working with horses.
