The sucking behaviour of lamb genotypes, selected for an increase or decrease in weaning weight and a random bred line, was studied during the first six weeks of lactation. Sucking frequency and duration were recorded as were lamb growth rates and lactation performance of the ewes. There were no apparent differences between the lines in sucking behaviour even with large variations between lines...

Allosuckling is a situation when a female nurses a non-filial offspring. It was described in various ungulate species; however for camels this is the first description of this behaviour. The aim of the study was to assess the occurrence of allosuckling in captive camels (Camelus bactrianus) and to test whether it can be explained as a 'milk-theft' (opportunistic behaviour of calves) or alternat...

This study evaluated the generalization, maintenance, and negative side-effects of Habit Reversal (HR) and Differential Reinforcement of Other Behaviour (DRO) in the elimination of thumb-sucking. Thirty children who sucked their thumbs or fingers excessively were randomly assigned to a HR, DRO or wait-list control group. Observation data were collected in three observation settings. Both proced...

The sucking behaviour of three litters o 1, 2, 5 and 9 days after birth. Records were later to determine the sucking time, teat pre each piglet. The smallest litter spent less The amount of competition amongst piglets was there was also evidence of territorial behavi After nine days the teat preference order had . the slowest growing litter. f 6, 8 and 10 piglets was observed at made on video t...

The aim of this quasi-experimental study was to examine the effects of maternal pethidine during labour on the developing breast feeding behaviour in infants in the first 2 h after birth compared with infants not exposed to pethidine. Forty-four healthy infants were observed immediately after birth. They were placed skin-to-skin on their mothers' chests. The development of mouth and sucking mov...

The effect of enrichment and breed line on belly nosing in early-weaned pigs was investigated over two studies. In a preliminary study, 291 piglets were weaned at 7 days-of-age and observed over two consecutive days (pigs ranged from 17 to 30 days-of-age at time of observation). Piglets were fed a liquid milk replacer diet for either 7 or 14 days following weaning. Pen environment was enriched ...

The new-born mammal has both nutritive and non-nutritive sucking requirements (Levy, 1934). When non-nutritive sucking is prevented, abnormal oral behaviour which can resemble the effect of apomorphine may be induced. The two types of sucking behaviour can be distinguished using equipment described by Stephens (1975). This consists of a wooden box lined with rubber sheeting. A rubber teat is in...
