abstract = "The paper describes the effects of different rearing conditions as
possible stressors on health, reproduction, growth, milk yield and quality of meat
and milk. It was pointed out that numerous internal and external factors of cattle
affect the physiological processes, health, reproduction, growth, milk yield and
quality of milk and meat as very strong stressors. They are especially important
when acting immediately after parturition, i.e. in the puerperium in cows and
immediately after birth in calves. In intensive cattle production, the most important
complex stressors regardless of origin, and physiological conditions in which these
animals are more susceptible to distress are parturition, calf birth, puerperium,
intensive lactation, machine milking, oestrus, high pregnancy, dry period,
grouping of animals, disturbed social relations, dehorning, castration, hoof
trimming, transport, sudden changes in microclimatic conditions and feed quality,
etc. Excessive disturbances before slaughtering cattle also cause a strong stress
reaction. In modern housing systems, animal disturbance, immobilization of
animals, restriction of movement, significant reduction of living space, strong
painful stimuli, dystocia, pain during uterine prolapse, castration and acute
inflammatory processes in the udder and uterus are also strong stressors.
Unfavourable social relations between animals in the group are usually very strong
stressors that lead to disturbances of their behavioural patterns. As a consequence
of the action of numerous stressors, behavioural disorders, reduction of growth and
milk production, the occurrence of metabolic and reproductive disorders, the
occurrence of infectious diseases, reduction of meat and milk quality most often
occur.",
