“…In contrast, the regression method suggested by World’s Poultry Science Association [ 8 ] requires a basal diet and diets supplemented with at least two concentrations of a test P source, making it more expensive and laborious. Furthermore, the negative endogenous loss of P can be estimated using the regression method due to its inherent limitation, which is not physiologically possible in chickens [ 20 , 21 ].…”

The objective of this study was to determine and compare the phosphorus (P) utilization of inorganic phosphates fed to broiler chickens using the direct method. On day 15 of age, six hundred forty 15-day-old male Ross 308 broiler chickens (initial body weight = 399 ± 38 g) were assigned to five experimental diets with 16 birds per cage in a randomized complete block design. The experimental diets consisted of four semi-purified diets containing monocalcium phosphate, monodicalcium phosphate, dicalcium phosphate, and tricalcium phosphate as the sole P sources. Additionally, a P-free diet was prepared to measure basal endogenous P loss. Chromic oxide was added to the experimental diets as an indigestible index. Excreta were collected per cage on days 17 to 18 of age, and all birds were asphyxiated with carbon dioxide on day 19 of age for ileal digesta collection. The cage was an experimental unit, and the number of replications per each treatment was eight except for the tricalcium phosphate treatment (n = 4). There was no interaction observed between the P source and the collection site (ileal digestibility vs. total tract retention). Phosphorus utilization differed (p < 0.05) among inorganic phosphates and the ileal digestibility of P was greater (p < 0.05) than the total tract retention. In conclusion, the standardized ileal digestibility of P in inorganic phosphates ranged from 56.7% to 89.8% and ileal digestibility was greater than the total tract retention.

“…Low P content of cereals may increase the proportional endogenous losses in digesta resulting in underestimation of AIPD values ( Lemme et al., 2004 ). Although the basal EPL is not affected by feedstuff characteristics while feed intake level may influences the basal endogenous losses ( Mutucumarana and Ravindran, 2016 ). The AIPD coefficients are inconsistent for the same feed ingredient among different studies resulting in high variation in estimated P digestibility ( Bohlke et al., 2005 ).…”

Pre-cecal phosphorus digestibility for corn, wheat, soybean meal, and corn gluten meal in growing Japanese quails from 28 to 32 d of age

The optimization of dietary phosphorus (P) depends on precise details of the P availability in feed ingredients to avoid excess or deficient P in a mixed diet. This study was carried out to measure the apparent ileal digestibility of P for corn, wheat, soybean meal, and corn gluten meal in growing Japanese quails from 28 to 32 d posthatch. A total of 400 quail chicks were randomly distributed across 5 treatments with 4 replicates and 20 birds in each floor pen. The P-free diet (PFD) was formulated based on cornstarch to measure the basal endogenous P losses (EPL). Digestibility coefficients were determined by ileal digesta sampling using TiO 2 as an indigestible marker. The EPL was estimated at 384 mg/kg DMI. The apparent ileal P digestibility (AIPD) for corn, soybean meal, wheat, and corn gluten meal were determined to be 0.38, 0.53, 0.38, and 0.78, respectively. The corresponding values for true ileal P digestibility (TIPD) were 0.48, 0.61, 0.50, and 0.83, respectively. The t -test analysis showed that the difference of AIPD and TIPD values for corn ( P = 0.031) and wheat ( P = 0.015) were statistically significant, however, no significant differences were observed for corn gluten meal ( P = 0.318) and soybean meal ( P = 0.104). In conclusion, the correction of AIPD coefficients for EPL in low-P ingredients such as corn and wheat may be much more important than that in high-P feedstuffs such as corn gluten meal and soybean meal in growing quails.

“…4.5 g/kg). Results from New-Zealand (Mutucumarana et al, 2016), however, showed that the precaecal P-digestibility coefficients of four PAPs ranged from 36 to 55%, indicating that the CVB Table with a precaecal-P digestibility coefficient of 62% may overestimate the P-digestibility values of current PAPs. A validation study, taking into account that the estimated dietary content for precaecal P of the experimental diets does not exceed birds requirement, has been recommended.…”

Krimpen, van M.M., P. Bikker and J. van Harn, 2018. Nutrient digestibility of processed animal proteins in broilers; . Wageningen Livestock Research, Report 1185. Summary UKProcessed Animal Proteins (PAPs) have long been banned from farm animal diets in the EU. In this period, raw material selection and processes to prepare PAPs have been improved and diversified allowing for a range of products available for inclusion in animal diets. As a consequence, the products and their respective specifications in present feedstuff tables do not cover the composition and quality of presently available PAPs. This report presents the methods and results of a study, conducted by Wageningen Livestock Research at the request of European Fat Processors and Renderers Association (EFPRA), in which the total tract digestibility of proximate components and ileal phosphorus, calcium and amino acid digestibility of 2 PAPs of pig origin in broiler chickens were evaluated. The results from this study showed that the chemical composition of the new PAPs are broadly similar to the 'former'PAPs, but that the AME and the digestibility of crude fat, crude protein and amino acids of the new
