Environmental enrichment in early life affects cortisol patterns in growing pigs.
Effects of environmental enrichment at different stages of life on stress physiology of pigs were investigated in a trial with 63 groups, each of four siblings. In each of the three growing phases (suckling 0 to 4 weeks of age, nursery 5 to 9 weeks, fattening 10 to 24 weeks) pens either were (=E) or were not (=0) enriched. Accordingly, the treatments were (i) 000, (ii) E00, (iii) EE0, (iv) 00E,...

Effects of environmental enrichment on behavioral responses to novelty, learning, and memory, and the circadian rhythm in cortisol in growing pigs.
Previously we showed that pigs reared in an enriched environment had higher baseline salivary cortisol concentrations during the light period than pigs reared under barren conditions. In the present experiment, it was investigated whether these higher baseline salivary cortisol concentrations were a real difference in cortisol concentration or merely represented a phase difference in circadian ...
متن کاملsecuritization of mortality risks in life annuities
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
15 صفحه اولEffects of environmental temperature on food intake in growing pigs.
l. The food intake of forty-seven young growing pigs has been measured during exposure to cold, thermoneutral and warm ambient temperatures. In some experiments the pigs were allowed to feed from an open bowl and in others they performed an operant response to obtain food. 2. When the pigs were housed at a thermoneutral temperature and transferred once a day to a high or low temperature before ...
