Abstract:

Animal’s feed intake is concurrently governed by short-term and long-term regulations,which balance the sensibilities for feed intake and prevent sinking into fasting or overeating.Animals may not get enough feed in a feeding bout,and a meal in accordance with satiety may contain many bouts.The intervals within a meal or between meals are feeding intervals.This review summarized the classification of feeding intervals,their characteristics for different animals,and introduced the valid method that estimated meal criterion by modeling feeding intervals and the impact of data structure on the distribution of feeding intervals,in order to lay the foundation for further analyzing the feeding characters and provide clues for the regulation in feeding behavior of animals.
