Title

Evaluation of Calcium and Phosphorus Digestibility in Di-calcium Phosphate Samples Produced in Iran in Male Broilers with Ileal and Total Gastro-intestinal Tract Methods

Pages

  452-462

Abstract

 BACKGROUND: Phosphorous is an essential nutrient for poultry. Receiving too much phosphorous by livestock and excretion of excess phosphorus, can lead to environmental pollution. OBJECTIVES: Determining the ileal and total tract Digestibility of phosphorus and calcium in Di-calcium phosphates produced in Iran. METHODS: A total of 720 day-old male Ross 308 Broilers were randomly divided into 8 treatments with 6 replicates of 15 birds in each. In control treatment phosphoric acid was used as a source of phosphorus. The other dietary treatments included one of the seven domestic samples of Di-calcium phosphates (A to G). Chromium oxide was used as a marker in the diets. On day 21, after collecting of feces, all birds were slaughtered via neck dislocation. Then, the last one-third of ileum was removed. The contents of the intestine were collected for each replicate and after drying were sent to the laboratory to determine the chromium oxide, phosphorus, and calcium amounts. Percentage of ileal and total tract Digestibility of phosphorus and calcium for each sample were calculated separately. RESULTS: The effect of type of Di-calcium phosphate samples in feed on ileal and total tract Digestibility of calcium and phosphorus was highly significant (P < 0. 001). Ileal Digestibility in control was 69. 8 percentage, while the lowest was observed in the E and F samples, and the highest value was related to sample A. Digestibility for phosphorus in control diet was 53. 4 percentage throughout gastrointestinal tract. The lowest amounts of total tract Digestibility of phosphorus were observed in treatments E and F, respectively, while the highest total tract Digestibility was related to treatment A with 47. 9 per cent. CONCLUSIONS: It could be concluded that ileal Digestibility is more accurate in evaluating phosphorus bioavailability and sample A had the highest biological value, while the lowest was related to the samples E and F.
