Introduction to Poultry Specialist
With the rapid development of intensive, large-scale poultry farming, due to poultry leg disease, low eggshell quality and the impact of increasing losses, according to statistics: domestic broiler morbidity rate of 2% -5%, mortality rate of up to 5%. At the same time, due to the poor quality of commercial eggs eggshell caused by a high proportion of broken eggs rate of 6% to 7%, which undoubtedly gives producers and operators to cause huge economic losses.
The reason for this is mostly due to the lack of mineral nutrition in poultry, resulting in bone, and medullary bone dysplasia. What are the feasible ways to improve the skeletal problems in poultry?
Firstly, understand the poultry skeleton and bone development
Leg problems and eggshell problems due to calcification
Skeletal development in laying hens and breeders
一、The three types of bones in poultry (avian) skeletons are:
1、Containing gas bone (increase the toughness of poultry bones, conducive to poultry flying)
2、Medullary bone (mineral reservoir) 3、Structural bone (partially mineralized)As can be seen in the picture, the poultry skeleton is based on a mineral matrix, of which 65% is mineral matrix, 25% organic matter and 10% water. Whereas, poultry bones are formed through endochondral osteogenesis and calcification of cartilage occurs at about 12 weeks of age.
By understanding the formation of poultry bones and bone structure, it helps the farmer to give the right advice on nutrition. Another important aspect is to differentiate between medullary and structural bone, as the particular medullary bone can be directly related to eggshell quality.
Factors associated with leg disease and eggshell quality problems:
Regarding the above, it is necessary to emphasize high production performance flocks, as the pressure of production makes the attention more on breeders or breeding, and in the past little attention was paid to skeletal development, which affects the final performance as well as the quality and conversion of the chicks.
For example, emphasizing the average daily gain, a gain of 20g per chicken at the first week of age can lead to an average daily gain of 93g per chicken at the sixth week, which means an almost fivefold increase.
For laying hens and breeders, 60-75% of the calcium used to form the eggshell comes from the feed and the remainder from the bone, but only calcium is available for the eggshell because all the phosphorus in the medullary bone is metabolized in the urine, so the bone is the reservoir of calcium during eggshell formation, and the health and size of the bone is very important for the quality of the eggshell. This is what we call a direct correlation between medullary bone and eggshell quality.”
★ Distribution of body tissues in daily weight gain at different feeding stages.
★ Larger eggs have less shell strength than smaller eggs.
★ Eggshell strength decreases with increasing hen age.
.Protein (very important from birth to 2 weeks of age)
Fat
Bone (structural bone grows in length and thickness from the beginning to the 12th week of age, after the 12th week of age the bone has reached its final size and the animal no longer grows taller)
Ossification in laying hens and breeders
Calcium and phosphorus deficiencies
Homogeneity of mixing
Problems with calcium-phosphorus ratio
Vitamin A\D\K dosage
Low levels of other micronutrients
Liver problems
Low phytase
Heat stress problems
When the medullary bone reserve is insufficient, it tends to lead to symptoms such as osteoporosis and keel bending in poultry
Therefore, we can use [Miaphos] liquid in the form of micro-quick supplementation, in the chicken farm to see the symptoms of feeding these products, can solve the eggshell quality, hen fatigue syndrome, cartilage disease and other major problems.
Since [Miaphos] liquid adopts the form of micro-quick supplement, we can feed these products when the chicken farms see the symptoms, to further solve the eggshell quality, hen fatigue syndrome, cartilage disease and other major problems.
So what makes this product so special?
First of all, Miaphos products are rich in phosphorus as well as the right amount of calcium, and also contain magnesium, manganese, copper, zinc, as well as stress-fighting electrolytes and the right proportional amounts of nutrients. The key thing is that this product is acidic (the picture below shows the PH test done by Javier during the live broadcast: the PH value is around 1). So not only the trace elements in the product itself, but also those in the feed ration are easily absorbed.
