“…For instance, lactating sows eat on average 8.7 meals per day [ 28 ], while gestating sows in feeding stations eat on average 1.17 meals per day [ 29 ]. Some authors mention that pigs eat continuously without pausing [ 30 ]. However, the literature supports that pigs consume several discrete meals per day [ 31 , 32 , 33 ].…”

Nutritional values of ingredients have been and still are the subject of many studies to reduce security margins of nutrients when formulating diets to reduce feed cost. In most studies, pigs are fed a limited amount of feed in a limited number of meals that do not represent how pigs are fed in commercial farm conditions. With free access to feed, pigs follow their intrinsic feeding behaviour. Feed intake is regulated by satiety and satiation signals. Reducing the feed intake level or feeding frequency can affect digestibility and transit time and induce metabolic changes. To reduce feed costs, alternative ingredients that are frequently rich in dietary fibre are added to diets. Fibre acts on the digestion process and transit time by decreasing energy density and causing viscosity. Various analyses of fibre can be realised, and the measured fibre fraction can vary. Exogenous enzymes can be added to counteract the effect of fibre, but digestive tract conditions, influenced by meal size and frequency, can affect the efficiency of supplemented enzymes. In conclusion, the frequency and size of the meals can affect the digestibility of nutrients by modulating gastrointestinal tract conditions (pH and transit time), metabolites (glucose and short-chain fatty acids) and hormones (glucagon-like peptide 1 and peptide tyrosine tyrosine).

“…The frequency and circadian distribution of meals vary considerably between species MARCILLOUX 1980, 1983;HIRSCH 1973;LE MAGNEN and TALLON 1963;METZ 1975;RASHOTTE et al 1984;SANDERSON and VANDERWEELE 1975). Under ad libitum feeding conditions, a significant positive correlation between meal size and duration of the subsequent IMI (post-meal IMI) has often been observed in the rat (BERNSTEIN 1975;DAVIES 1977;DE CASTRO 1975;LE MAGNEN and DEVON 1984;TALLON 1963, 1966;ROSENWASSER et al 1981;THOMAS and MAYER 1978) and also in some other species (AUFFRAY and MARCILLOUX 1983;HANSEN et al 1981;RASHOTTE et al 1984;SANDERSON and VANDERWEELE 1985). This post-meal correlation indicates that food intake is regulated from meal to meal, with a meal-related postprandial factor contributing to the maintenance of post-prandial satiety (LE MAGNEN and DEVOS 1984;LE MAGNEN and TALLON 1963).…”

The meal pattern of ad libitum fed pygmy goats was recorded and analyzed (12 h light/12 h dark). Pygmy goats, adapted to a complete pelleted diet, consumed 12 meals per day. Eight meals, corresponding to about 63 % of total daily food intake, occurred during the bright phase and 4 meals during the dark phase of the lighting cycle. Mean meal size was greater during the dark phase than during the bright phase. Meal size was positively correlated with the duration of the post‐meal interval during the dark phase and with the duration of the pre‐meal interval during the bright phase. The results demonstrate that food intake in pygmy goats follows a distinct circadian cycle. Further, food intake of pygmy goats is apparently regulated from meal to meal, with different factors prevailing during light and dark. Zusammenfassung Verzehrsmuster von Zwergziegen bei ad‐libitum Fütterung eines pelletierten Alleinfutters Das Verzehrsmuster von ad libitum gefutterten Zwergziegen wurde kontinuierlich registriert und analysiert. Die an ein pelletiertes Alleinfutter adaptierten Tiere fraßen durchschnittlich 12 Mahlzeiten pro Tag (12 h Hell‐/12 h Dunkelphase). Davon entfielen 8 Mahlzeiten, entsprechend ca. 63 % der gesamten täglichen Futteraufnahme, auf die Hellphase und 4 Mahlzeiten auf die Dunkelphase. Im Mittel waren die Mahlzeiten in der Dunkelphase größer als in der Hellphase. Während der Dunkelphase war die Mahlzeitengröße mit der Dauer des jeweils folgenden, während der Hellphase mit der Dauer des jeweils vorangehenden Mahlzeitenintervalls positiv korreliert. Die Ergebnisse zeigen eine deutliche circadiane Rhythmik des Verzehrsverhaltens von Zwergziegen. Ferner wird die Futteraufnahme von Zwergziegen anscheinend von Mahlzeit zu Mahlzeit reguliert, wobei während der Hell‐ und Dunkelphase unterschiedliche Faktoren von Bedeutung sind.
