Communication during suckling in the domestic pig

Fan noise disrupted communication between sows and piglets during nursing, resulting in slower piglet growth. Certain indications were found that suggested that the noise-exposed piglets gained less milk than the ones in the silent environment.

Improving the laboratory environment for nonhuman primates

Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches, mirrors, and foraging devices, and...

Effects of an enriched environment on subsequent fear reactions of lambs and their mothers

From birth to weaning (3 months of age), 20 lambs were reared by their mothers in an enriched environment [colored mobile objects plus human-like figure]. Subsequently, this resulted in reduced fear reactions in the mothers, but not in the lambs.

Abnormal behavior in a captive chimpanzee colony

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers had less abnormal behavior. Access...

The effect of mother-infant separation in captive baboons on time intervals to first postpartum estrus, confirmed pregnancy and subsequent parturition

It is generally thought that early forced-weaning of infants would reduce the time from parturition to the first fertile postpartum estrus thus maximizing reproductive efficiency. ... From a survey of 23 animal records we determined the following values for mothers...

Effects of environmental enrichment on care-giving and infant development in marmosets

Twin infants from eight family groups were observed for the first 10 weeks of life. Non-enriched enclosures contained a nest box and branches. Enriched enclosures also had an artificial gum tree to stimulate the marmosets natural exudate gouging behaviour, wooden...

Artificial weaning of calves: Benefits and costs

Evidence indicates that allowing beef calves to stay in the maternal herd beyond the age of natural weaning promotes animal welfare and may enhance the cows' natural reproductive potential.
