| Abstract: | Feeding behavior has been analyzed in Large-White and Chinese pig breeds. Maximally automatized apparatuses, especially adapted to animal size, were used. Besides the usual parameters measured such as food intake, meal size, meal duration, meal frequency, intermeal intervals and postprandial correlation, these apparatuses also permitted us to measure the rate of intake during the meal. This rate was constant throughout the meal in ad libitum conditions and after 24-hour deprivation. A positive correlation between meal size and length of the postmeal interval was found in only half of the animals. During this work, we began to study the mechanisms initiating food intake. |
