It is not clear whether pig calls are discrete or continuous in form and function, and whether they are specific signals. The aim with this study was to try to classify piglet vocalizations uttered during nursing, and the hypothesis was that the sounds are, in fact, structurally discrete. All vocalizations uttered during 33 nursings in 3 litters during 3 days after farrowing were recorded, and 106 sounds were processed in a spectrograph. The spectrograms were analysed by the following method. Firstly, they were classified in groups on the basis of a number of physical parameters which were quantified for each spectrogram. Secondly, the inter-class dissimilarity was tested with single-link cluster-analysis. Thirdly, the correlation of the physical parameters was tested within classes with correlation and regression calculations. The analysis supported the existence of 5 discrete classes of piglet vocalizations: croaking; deep grunt; high grunt; scream; and squeak. In croaking, scream and squeak there was a correlation between basic frequency and time, indicating a continuous variation of intensity within the discrete call classes. It was further concluded that any viewpoint on the function of the sounds must be based on studies of statistical links between specific signals and certain behaviour in the receiver.</p></div>","PeriodicalId":100106,"journal":{"name":"Applied Animal Ethology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1984-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-3762(84)90030-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89474386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within 10 minutes of having stopped feeding, one of the others from its group was put in the adjacent stall and allowed to feed. In all cases, the apparently satiated pig started to feed when the newly-introduced pig started to feed. When used as the remaining pig, the dominant pig in each group fed for longer and ate more than the other-ranking pigs when a hungry pig was introduced into the next-door stall. In order to test whether the resumption of feeding was due to the cessation of isolation or due to the feeding behaviour of the introduced pig, a second experiment was performed. The same groups were used plus another group of three similar pigs. After 12 hours of food deprivation, two pigs were left in adjacent stalls and allowed to feed until satiated. The third member of their group was then introduced and allowed to feed in a stall facing the other two. In all cases the remaining pair fed for appreciable periods. These results confirm that social facilitation, as defined here, occurred in the feeding behaviour of these pigs.</p></div>","PeriodicalId":100106,"journal":{"name":"Applied Animal Ethology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1984-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-3762(84)90033-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75009241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two of the pigs were on continuous light, and 2 were on 8.5 h light and 15.5 h of darkness. The 2 pigs in each treatment were in adjacent stalls but well separated from the other pair and other pigs. There were no differences in total food consumption between the animals in the 2 treatments. Eating speed also did not differ between treatments; neither did it differ between body-weight stages when adjusted for body weight. The percentage of the total time devoted to feeding differed between body-weight stages but not between treatments. However, over the first 8-h period of the day, the pigs on the short day-length spent more time feeding, but body weight did not affect this measure. Meal intervals were determined by a logarithm survivorship curve analysis, and it was found that pigs on the long day-length had significantly more meals than the others. Body weight also affected the number of meals, with the youngest taking most.
