Rick- hyperparathyroidism is a condition characterized by ets can be caused by inadequate dietary intake of hypercalcemia caused by the release of hormone-like calcium, phosphorus or vitamin D3 or by an improper substances from nonendocrine tumors; however, calcium:phosphorus ratio. With calcium and vitamin with neoplasm, hypercalcemia may also occur from D deficiencies, the resulting hypocalcemia induces widespread skeletal deposits of metastatic tumors, enlargement of the parathyroid gland (nutritional with associated increased osteoclastic activity. Consistent para- trary to the situation in man and domestic mammals, thyroid gland changes are not typical with a phos- primary hyperparathyroidism and pseudohyperpa- phate deficiency or excessive calcium intake. Tachypnea and polycythemia have been observed in Secondary nutritional hyperparathyroidism is com- birds with rickets, presumably because of poor rib monly reported in birds secondary to a calcium-defi- strength and infolding of ribs. The resorbed osseus tissue can be re- placed by fibrous tissue (osteodystro- phia fibrosa). The cortical bone can become so thin that spontaneous fractures may occur, especially in the vertebrae, ribs, tibiotarsus, tar- sometatarsus and femur. The frac- tures are typical for demineralized bone and are called “greenstick frac- tures. Plasma calcium concentrations remain gen- erally normal until the end stage of the disease, when tetanic convulsions may be observed. Although cal- cium deficiencies accompanied by pathologic frac- tures seem relatively common in psittacine birds, nutritional osteodystrophia fibrosa is rarely diag- nosed. A possible explanation might be that his- tologic examination of bones is not often performed. Osteoporosis To a certain degree, osteoporosis (cage layer fatigue) is physiologic during egg production. The hen had a three-year history of egg laying and had recently laid her second egg of the year. The bird appeared to have head tremors, was unable to stand and both wings were drooping. Histopathology indicated egg-related peritonitis, parathyroid hyperplasia and severe osteoporosis suggestive of secondary nutritional hyperparathyroidism. Etiologic factors may be immo- bilization, which is a well known cause for osteoporosis in man, and marginal nutritional calcium defi- ciency, which can alter the physi- ologic osteoporosis from high egg pro- duction into severe osteoporosis with associated clinical signs.

Folic Acid (Folacin) Folic acid is the compound pteroylmonoglutamic Vitamin C and iron may improve the bioavailability acid. The only exceptions are a Folates are generally widely distributed in foods and few plants, such as peas, beans, spirulina and kelp, are present as the polyglutamic derivatives of folic that may be able to synthesize minute amounts of acid. These are converted by hydrolysis to free folic this vitamin, although this accumulation is likely acid and absorbed by both an active transport system due to their close symbiotic association with bacteria. The absorption process is only moderately efficient Naturally occurring vitamin B12 occurs in the coen- (<50%). This complex is broken, primarily through the normal action of pepsin and Folic acid’s primary metabolic role is in the transfer trypsin. Free vitamin B12 is absorbed by the intesti- of single-carbon moieties in a wide variety of reac- nal tract via an efficient active transport system tions. This function is particularly important in involving a vitamin B12 specific-binding protein. At amino acid metabolism, in the bioconversion of very high levels, simple diffusion occurs throughout amino acids and in the biosynthesis of nucleotides. Because of folic acid’s requirement in the synthesis of Most of the vitamin B12 in the body is found in the three of the four nucleic acids, a deficiency results in liver with secondary stores in the muscle. It interacts with several other fatty acid transport and utilization, and is therefore nutrients such as folic acid, pantothenic acid, choline necessary to prevent hepatic lipidosis in the normal and methionine.
