The primary aim of this study was to assay the influence of dietary Ca sources and levels on performance, egg quality indices, and selected blood variables of laying hens. A total of 192 Bovanz commercial layers were distributed to 6 dietary treatment groups with 4 replicates and 8 birds in each replicate. The experimental diets were iso-caloric and iso-nitrogenous, but they were different in t...

A factorial experiment in a randomized complete block design was conducted with 192 pigs to evaluate the effects of two levels of d i e t a r y ca l c ium:phospho rus (.90/.70 or .65/.50%, respectively) in an 18% protein diet for growing swine (19 to 52 kg). Animals were then continued to market weight being fed one of two levels of calcium:phosphorus ( .65/.50 or .50/.40%, respectively) each a...

Studies were conducted to evaluate the level of dietary 1,25-dihydroxycholecalciferol [1,25-(OH)2D3] required to decrease the incidence of tibial dyschondroplasia (TD) in male broilers at 3 and 5 wk of age. The birds were reared in floor pens with wood shavings and fed a corn-soybean meal diet supplemented with 0, 3, 6, or 9 micrograms/kg 1,25-(OH)2D3. The diet contained, by averaged analyses, ...

Four vegetables brinjal, bitter gourd, colocasia and tomato were subjected for total protein, crude fiber, ash calcium, magnesium, phosphorus, potassium, ascorbic acid and folic acid contents in raw peeled raw cooked and peeled cooked forms. Losses of nutrients due to peeling and cooking were determined. The loss of protein was non-significant during peeling and was significant during cooking e...

Problem statement: There is evidence that the type of fiber influences the development of nephrocalcinosis in rats, but the effect of pectin was unknown. Approach: The effects of dietary pectin and cellulose on kidney calcification were studied in female rats. The diets used contained either 0.4-0.6% phosphorus and either cellulose (10%, w/w) or pectin. The purified diets used were balanced for...

THe effect of three levels of non-phytate phosphorus (NPP) (3.0, 2.1, and 1.7 g/kg) and two levels of 3-phytase (F) (0 and 150 phytase units (FTU)/kg) together with a high dietary calcium concentration (approximately 41.0 g/kg) on the performance characteristics, egg quality, pH of the digestive tract, and tibia bone quality of ISA Brown hens housed in enriched cages was evaluated. THe diets wi...

background/objective: hyperphosphatemia is the consequence of end stage renal failure. inadequate control of serum phosphorus results in elevated ca × p product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  in this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis pat...
