The importance of feeding is sufficient to meet the requirements of chicken to produce clear, clear quality shell eggs. The need for laying hens to calcium during infinite production is high. So that a chicken with an average of 250 eggs a year requires about 56 kg of calcium, which is 25 times the amount of calcium in its bones. For this reason, most laying hens diet contains 3-4 calcium percentages to meet their needs.
Laying chicken is 100% unable to provide calcium from available sources of rations. Sometimes the availability of calcium is unclear, and it should be noted that when calcium availability is low, daily intake of calcium is needed.
The non-equilibrium of the ratio of phosphorus to calcium and high content of phosphorus in the diet has a negative effect on shell quality. In any case, what seems most important is that the egg shell should be as sturdy as possible to maximize the market.
Many of the factors cause egg shell fractures, and shell fractures are directly related to the quality of the shell. Factors involved in this include nutrition, diseases, management effects, and environmental conditions. Most quality eggs laid by commercial laying hens contain about 2.2 grams of calcium in calcium carbonate, and about 95 percent of the dry weight of the egg shell forms calcium carbonate. The shell also contains 3 /. The percentage of phosphorus and 3 /. The percentage of magnesium, sodium, potassium, and scarce elements such as zinc, iron, manganese and copper.
According to the above information, it can be concluded that egg shell as a calcium-rich source as well as a good proportion of phosphorus to calcium and the presence of trace elements can be used in the diet of livestock and poultry and is a very suitable alternative to Calcium is mineral.
Pars Eileen Mehr Conversion Industries Co., in order to achieve this goal by launching an egg shell processing and heat treatment process as well as the resulting crust mill, a product free of any microbial contamination with the mentioned advantages along with the health certificates of the veterinary organization of the country At the service of a large family of livestock and poultry breeders, and livestock and poultry and aquaculture companies.
This product, as a rich source of calcium and having a good proportion of phosphorus to calcium, can be used as a nutritional supplement for livestock and poultry and is an appropriate alternative to mineral calcium.
