The nutritional value of cage-fed chicken water is often overlooked, but the lack of water can quickly have serious and irreversible adverse effects on a variety of chickens.The loss of drinking water caused the chicken to die more quickly than the loss of any other nutrient, leading to the fastest decline in production levels.Therefore, water is the most important nutrient for chicken.
(1) water distribution in the chicken body: water exists in every cell of the chicken body. The water content of the egg is about 65%, that of the chick just out of the shell is about 85%, they are rearing on ground , and that of the adult chicken is about 55%. The are rearing in chicken cage, As a result, water content in chickens ranges from 55 percent to 85 percent.The moisture inside chicken body is with first young highest, and inside body moisture grows along with day age with extremely fast rate drops, later drop rate slows down gradually, till adult, moisture content inside body is relatively stable.
The water in chicken is mainly in the intracellular fluid and extracellular fluid, and the water in the extracellular fluid is in the interstitial fluid and plasma respectively.In the total water content of chicken body, the water in intracellular fluid accounts for 50%, the water in interstitial fluid accounts for 5%, and the water in plasma only accounts for 5%. The advantage in chicken cage is that chicken move less, consume less water.
(2) the role of water: water plays an extremely important role in chicken metabolism.Most of the water in the body is combined with protein to form a liquid, so that the tissue cell fluid presents a certain shape.Therefore, water is necessary to ensure the normal shape of all organs in the body.
Water is the solvent of nutritive substance. The absorption, metabolism and waste excretion of nutritive substance in chicken, as well as the transport of nutritive substance between tissues and organs in the body must be completed by dissolving in water.Water is also involved in chemical processes in the body and ACTS as a mediator for chemical reactions during metabolism.Water has the characteristics of large heat capacity and high heat of evaporation. Therefore, water is of great significance for regulating and maintaining the humoral balance.In addition, water also ACTS as a lubricant to keep the articular surfaces of the bones lubricated and mobile.
(3) water source: there are three ways for chickens to obtain water, namely drinking water, metabolic water and feed water.
Drinking water: chicken daily free drinking water in the human body, about 75% of the total intake. There are automatic drinking line in chicken cage system
Metabolize water: call oxidation water again, it is the water that shows nutrient material oxidation produces inside airframe.
Feed water: that is, the water intake of animals with the feed.The feed water content of cage-raised chickens varies greatly with the type of feed. The normal air-dried feed water content is between 8% and 15%.Under intensive feeding conditions, the water intake of chicken feed can meet about 6% of the total moisture content of children.
