Varied milk delivery contingencies differentially affect sucking in rat pups as measured by jaw-muscle electromyographic activity. In Experiment I we found that 11-13-day-old pups sucked more frequently when receiving tiny intermittent pulses of milk than when receiving no milk, and continued to suck at a high rate for at least 30 min after cessation of milk delivery. In subsequent experiments ...

BACKGROUND There appears to be a perception amongst parents and in popular literature that infantile colic is caused by feeding difficulties. Limited support for this perception is found in scientific literature. Whilst there is scientific evidence that suck, swallow and breathing are key components of successful feeding, these components and the coordination thereof in infants with colic have ...

Background: the sucking development pattern of the preterm newborn (PTNB) in the neonatal period is important for an effective sucking and oral motor development. The establishment of a safe and efficient feeding in pre-term newborns is related to a rhythmic and coordinated sucking. Nonnutritive sucking stimulation can have an influence on the development of sucking and the development of sucki...

Prolonged duration of finger- and pacifier-sucking may be a risk factor for maldevelopment of orofacial structures and dental occlusion. This study assessed the prevalence of nutritive and non-nutritive sucking habits and their association with some contributing factors among 7-year-old girls in Mashhad, Islamic Republic of Iran. Based on a questionnaire to the parents of 436 schoolgirls, the r...

Nutritive deprivation, suckling deprivation, gastronintestinal fill, and milk availability contribute to the control of sucking (as measured by jaw-muscle electromyograph) and ingestion of milk (provided via a tongue cannula) in 11-13-day-old rat pups. Depriving pups of the opportunity to suckle reliably increases subsequent sucking and milk intake. Intraoral delivery of milk also increases suc...

Opening of the pre-orbital gland in red deer (Cervus elaphus) was previously found to be associated with feeding and negatively associated with achieving satiety in bottle-reared red deer calves. We speculated that this acted as a signal from a calf to the mother that it was hungry. Thus, we focused on a possible association between the pre-orbital gland opening and the sucking behavior in red ...

BACKGROUND Improvement of dairy farms economics requires intensification, automatic milking, and artificial rearing methods. The ability to express normal behavior is one of the five freedoms to achieve animal welfare, whereas the display of abnormal behaviors is considered as an indicator of poor welfare. Cross-sucking is defined as sucking any body parts of pen-mate calves, whereas inter-suck...

Feeding behaviour is a complex functional system that relies on external signals and the physiological state of the animal. This is also the case in ants as they vary their feeding behaviour according to food characteristics, environmental conditions and - as they are social insects - to the colony's requirements. The biogenic amine serotonin (5-HT) was shown to be involved in the control and m...

Results: Pacifier sucking was more frequent than thumb sucking. Exclusive breast feeding was not reported for children either in the 6th or 12th month of age, and approximately 70% were already receiving artificial feeding. There was no association between family social profile and sucking habits, but lower rates of breastfeeding was associated with pacifier sucking in the 12-month old children...
