(ii) secretion of mucus which helps in adhering theundigested)particles together and lubricating it for an easy passage.The undigested, unabsorbed substances called faeces enters into the caecumof the large intestine through leo-caecal valve, which prevents the back flow ofthe faecal matter. It is temporarily stored in the rectum till defaecation.The activities of the gastro-intestinal tract are under neural andhormonal control for proper coordination of different parts. The sight, smelland/or the presence of food in the oral cavity can stimulate the secretion ofsaliva. Gastricand intestinal secretions are also, similarly, stimulated byneural signals. The muscular activities of different parts of the alimentarycanal can also be moderated by neural mechanisms, both local and throughCNS. Hormonal control of the secretion of digestive juices is carried out bylocal hormones produced by the gastric and intestinal mucosa.CALORIFIC VALUE OF PROTEIN, CARBOHYDRATE AND FAT(Boxed Item Not for evaluation)The energy requirements of animals, and the energy content of food, arehoot mwhentio the timete for​
