Comparison of endogenous amino acid losses in broilers when offered nitrogen-free diets with differing ratios of dextrose to corn starch

Huajin Zhou et al.

Summary: The optimal ratio of glucose and corn starch in a nitrogen-free diet (NFD) was investigated to simulate the normal intestinal physiology of broiler chickens and improve the accuracy of ileal endogenous amino acids (IEAAs) determination. Higher ratios of D/CS in NFD increased IEAAs by promoting digestive enzymes and mucin secretion. However, an excessive proportion of starch in NFD was not suitable for chicken digestion. The ratio of D/CS at 0.33 in NFD was found to be more appropriate for detecting IEAAs in broiler chickens.

Progress in ileal endogenous amino acid flow research in poultry

V. Ravindran

Summary: The progress in understanding the endogenous protein concept in the past century, especially the composition and importance of endogenous protein loss in the terminal ileum of poultry for estimating feed digestibility, has been reviewed. The distinction between basal and specific losses, the lack of direct measurement methods for specific endogenous losses, and the relevance of taurine as a component of endogenous protein flow in poultry were highlighted. Additionally, the features, applications, and challenges of available methodologies, along with practical difficulties in using published endogenous amino acid loss values for digestibility corrections, were briefly outlined.

Nutrition and Digestive Physiology of the Broiler Chick: State of the Art and Outlook

Velmurugu Ravindran et al.

Summary: The first week after hatch poses significant challenges for broilers as their immature digestive tract undergoes dramatic changes to efficiently digest and absorb nutrients. As the birds grow older, limitations in digestive enzymes and absorptive surface area are overcome, leading to improved nutrient utilization. Early nutrition interventions can help chicks develop their digestive functions, enabling them to grow efficiently and reach their genetic potential.

Standardized ileal phosphorus digestibility of meat and bone meal and poultry byproduct meal for broilers

Felipe Dilelis et al.

Summary: Two experiments were conducted to determine the standardized ileal phosphorus digestibility coefficient of meat and bone meal (MBM) and poultry byproduct meal (PBM) for broilers. The results showed that the P in MBM is not as readily available as previously believed, while PBM can be considered an excellent source of phosphorus for broiler diets.

Measurement of Endogenous Phosphorus Losses in Broiler Chickens

Ruvini K. Mutucumarana et al.

Summary: The experiment aimed to estimate ileal and excreta endogenous phosphorus losses in broiler chickens. Results showed that the endogenous phosphorus losses varied significantly depending on the assay diet used, with higher losses in birds fed a casein-based diet compared to P-free and gelatin-based diets. Additionally, there was a significant interaction between the assay diet and site of measurement.
