    It is important to minimize stress for cattle because of animal welfare and profitability. This study aims to reveal how long after abrupt weaning the cow and her offspring show a need to rebuild the connection if physical barriers are removed and distances disappear. The research was carried out on Szamárhát Farm owned by the Tiszatáj Foundation, Hungary. In the autumn of 2019, thirty-one calves were weaned, randomly selected from 81 grey cattle cows’ offspring. The oldest calf was 10 months old, while the youngest one was 6 months old on the day of weaning. They were divided into three groups and reunited with the cows during the first, third, and fifth weeks after weaning. Each reunion happened in the early afternoon and the cow and her offspring spent 24 hours together again. The formation and the strength of the connection were recorded for an hour three times during this period, first in the afternoon, then in the morning, and the next afternoon. It can be seen that both parties showed the need to form the connection during the first week after weaning because the bond made between them was obvious in a short time. The connections proved to be strong. However, neither the cows nor their offsprings showed any intention to form strong connections in the third and fifth weeks. In the majority of the cases, no connection was formed.

    Piglets in commercial intensive pig husbandry are often abruptly weaned between 3 and 4 weeks for economic reasons. The process of weaning is a multifactorial stressor, in which nutritional, social, physical and psychologic stressors are combined. Piglets are often exposed to unfamiliar piglets around weaning which results in a period of vigorous fighting. Stress plays an important part in welfare research. Traditionally glucocorticoids are measured in blood samples but their use is often limited as the act of sample collection may stress an animal. Measurement of faecal cortisol/corticosterone metabolites is a non-invasive method for evaluation adrenocortical activity. The aim of this study was to examine the effect of litter’s let-together system (“kindergarten”) in the farrowing house by measuring faecal cortisol metabolites. According to our results the “kindergarten” system has no stress effect on sows and piglets, respectively.

    This study aimed to examine whether litters’ let-together system before weaning (‘kindergarten-system’) has any stress effect and effect on post-weaning behavior, respectively. One week before weaning piglets were socialized by removing four adjacent farrowing crate walls. After weaning, piglets from the same experimental groups were housed in the same rearing crates. The piglet’s body weight was measured at birth than weekly till the 7th life-week. Fecal cortisol metabolites were measured for evaluation of the adrenocortical activity. Personal observation and evaluation were carried out for behavioral analyses after weaning. There were no significant differences in weight development and cortisol metabolite levels between the control and experimental groups. Behavioral analysis showed that pigs grow up in a socialized system, rapidly evolve ranking in the rearing crates, and the self-maintenance and social behavior were more pronounced. In control groups, the activity involving movement (exploring, walking, and running) was much more decisive. Recent work suggested the beneficial effect of the ‘kindergarten’ system in the farrowing house in animal welfare aspects.
