Together with top food scientists and world-renowned chefs we made ready to heat broths and soups that are both delicious and nutritious.

By the 3rd laying cycle production may drop off sharply. If you don’t want to let go of your favorite hens, consider adding a few new members to your flock for continued productivity. The inside of the stomach is a very acidic environment, especially after food has just been eaten.

Stomach acid is a helpful substance but is potentially harmful as well. Fortunately, our body has ways to protect us from any harmful effects.

Hen’s lay the most eggs in their first laying cycle. Starting at about 20-weeks of age, where you can expect about an egg a day per young bird in the first cycle. This will slowly reduce over time.

Specialized exocrine cells of the mucosa known as mucous cells secrete mucus into the lumen of the stomach and into the gastric pits. This mucus spreads across the surface of the mucosa to coat the lining of the stomach with a thick, acid- and enzyme-resistant barrier.

sphincter forms valves in the digestive system. The gastro-esophageal sphincter is located at the stomach end of the esophagus.

This process, known as gastric emptying, slowly repeats over the 1-2 hours that food is stored in the stomach. The slow rate of gastric emptying helps to spread out the volume of chyme being released from the stomach and maximizes the digestion and absorption of nutrients in the intestines. The esophagus connects to the stomach at a small region called the cardia. The cardia is a narrow, tube-like region that opens up into the wider regions of the stomach. Within the cardia is the lower esophageal sphincter, a band of muscle tissue that contracts to hold food and acid inside of the stomach.

Grossly, the crop and gizzard were filled with undigested guinea corn and rice grains. There was a garlic‐like odour of the crop contents. The trachea mucosa had a mucoid exudate that almost completely occluded it.

Therefore, the inhibition of fatty acids synthesis caused by high light intensity was likely due to the carbon source consumption for the synthesis of polysaccharides. However, further studies are necessary to reveal this mechanism.

Although the D- birds consumed more feed and had a greater villous surface area than the D+ birds, the D+ birds had faster growth rates than the D− birds. However, the ability to digest starch, protein and lipids was shown to be lower in the D− compared with D+ line.
