Sample text

Distension of a balloon in the stomach depresses intake, but does not completely abolish feeding, while intra-gastric administration of the amount of food normally taken in a meal also depresses, but does not totally inhibit, feeding showing that stomach distension is not the only controller of intake. Clearly, the presence of food in the stomach and/or its passage through and absorption from the intestines are important factors in inducing satiety, but not the sole factors. Dilution of food with non-nutrients, or ‘dietary bulk’, reduces the concentration of nutrients in the food so that more food is eaten before nutrientinduced satiety occurs.

Poultry Feather pecking can occur in all types of poultry, especially if insufficient trough space is provided. g. by giving some whole grains in the food or on the floor, but this does not necessarily alleviate hunger (de Jong and Jones, 2006). Feather pecking sometimes leads to body pecking and wounding. Egg eating by hens may be an indication of mineral deficiency in the diet, as it is reduced by providing grit, although this again may be a question of lack of variety of activities rather than a nutrient deficiency.

Circadian Rhythms of Feeding Rats eat more frequent and larger meals at night than during the day, as they are nocturnal animals, while farm mammals are more active during the day and eat a greater proportion of their meals in daylight than at night. Poultry Unless the nights are very long, poultry do not eat during the hours of darkness, so there is a very marked diurnal rhythm of feeding. Savory (1979) observed a peak of feeding activity and intake during the hour before dusk, presumably to fill the crop as a reservoir of food to last the bird through the night.
