What are Proteins? They are organic compounds that contain carbon, hydrogen, oxygen and nitrogen and sometimes phosphorus, iron and sulfur.
So why are they Needed? To grow new tissues and to repair old tissues rebuild muscle and maintain cellular structure in an animal, every day 3 to 5% of the body’s proteins are rebuilt which the highest amounts are found in the muscles of animals.
It is no wander that the most common nutrient deficiency is that of proteins since a lot of meals do not have the nutrient deficiency needed. Sources of protein come from fish, red meats, chicken, turkey soybean cottonseed legume hay.
If proteins are starved from the body then this can result in slow growth rate, low birth weight and lower milk production, young animals are in more need than older animals, animals in gestation or lactation stages also need higher levels of proteins.
Combinations of proteins are amino acids which are classified as either essential or non-essential therefore the essential amino acids must be supplied which the ten essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.
So, what happens with insufficient proteins? Is a reduction in protein synthesis within the cells. Each cell contains millions of protein molecules and continually produces new protein to replace older protein molecules. If not enough essential amino acids in the body, it cannot access the compounds needed to make up new protein which will ultimately slow new protein production. This means tissue will break down since the cells cannot rely on the diet to supply the amino acids needed for protein synthesis the body begins to break down existing proteins as a source of amino acids.
The result is prolonged protein deficiency leads to tissue loss, especially a loss of protein rich muscle tissue because it breaks down muscle tissue as a resource of energy.
