Feeding frequency refers to the number of feeding times per unit time (one day) for feeding animals, which is an important factor affecting the digestion and absorption of nutrients in animals. Moreover, feeding frequency can also play a regulatory role in nitrogen metabolism and nitrogen deposition. Therefore, it is vital in pig production to explore the appropriate feeding frequency in order to improve feed utilization and alleviate feed waste to a certain extent. In this paper, the effects of feeding frequency on feed intake and nitrogen utilization of swine were reviewed to provide a reference for scientific feeding and management in pig production.
Key words: swine; feeding frequency; feed intake; nitrogen utilization
