This study was carried out to evaluate the effects of different phosphorus sources, in diets of growing cattle, on apparent partial and total nutrient digestibility; ruminal parameters; microbial efficiency synthesis and plasma phosphorus. Four Holstein steers weighting 280 kg and implanted with ruminal and duodenal cannulas were used. The experimental design was a 4 × 4 Latin Square and treatments were four supplemental phosphorus sources in the diet as follows: dicalcium phosphate (DP), supertriple phosphate (SP), monoammonium phosphate (MP) and […]
Keywords: dicalcium phosphate; microbial synthesis; monoammonium phosphate; rock phosphate; supertriple phosphate

The objective of this study was to evaluate the monoammonium phosphate (MAP) as a source of phosphorus and Paraíso limestone (CP) with higher magnesium levels (1.92%) as a source of calcium for commercial layers. A total of 280 white Dekalb chickens were housed in individual cages during the period from 46 to 58 weeks old. A completely randomized experimental design, with four diets, seven replicates and ten birds per experimental unit were used. The diets were: FBC/CB – dicalcium phosphate […]
