Evaluation of Eppawala rock phosphate as a phosphorus supplement in diets for growing chickens and pigs

Evaluation of an indigenous source of rock phosphate as a supplement for broiler chickens.

This study investigated the effects of replacing dicalcium phosphate (DCP) with Hazara rock phosphate (HRP) on the growth performance of broiler chickens. The purpose was to determine the maximum level of F that could be well tolerated. The HRP (13.16% P and 2.98% F) was incorporated into a standard corn- and soybean meal-based diet by replacing 0, 25, 50, 75, and 100% of DCP based on P. Each t...

Influence of dietary phosphorus concentration on the digestibility of phosphorus in monocalcium phosphate by growing pigs.

An experiment was conducted to test the hypothesis that the dietary inclusion rate of P does not influence the digestibility of P. The experiment was conducted at 4 experiment stations where the same protocol was followed. A total of 60 growing pigs (initial BW: 22.22 +/- 2.13 kg) were allotted to 6 dietary treatments with 10 replications per treatment. All pigs were placed in metabolism cages ...

Another Look at Calcium & Phosphorus Levels in Diets for Growing - Finishing Pigs

In addition to their role in the development and maintenance of the skeleton in pigs, calcium and phosphorus are involved in many other physiological processes. In practical swine diets, calcium can be considered an inexpensive nutrient. Phosphorus, on the other hand, is the third most expensive nutrient after energy and protein (amino acids). As the utilization of phosphorus in swine diets is ...

Phosphorus fractions in manure from growing pigs receiving diets containing micronized peas and supplemental enzymes.

Different livestock feeds manipulations have been reported to reduce the total P concentration in manure. Information on the influence of these dietary manipulation strategies on the forms of P in manure is, however, limited. This study was, therefore, conducted to investigate the effect of diet manipulation through feed micronization and enzyme supplementation on the forms of P in swine manure...
