Different Levels of Digestible Methionine on Performance of Broiler Starter

Animal Production: Indonesian Journal of Animal Production, 2010
Dietary protein and amino acid supply is the most expensive component of poultry diets. Therefore several efforts made by the industry to minimize the cost of the protein portion of the diet.

The Efficiency of AMEn and TMEn Utilization for NE in Broiler Diets

Brazilian Journal of Poultry Science, 2016
The experiment was conducted to evaluate the feed intake, body weight gain, total energy (kJ), protein (g) intake, energy and protein efficiency ratio (EER, PER), net energy, and metabolic body weight, on two commercial broiler chickens (Arian and Ross ...

Initial assessment of protein and amino acid digestive dynamics in protein-rich feedstuffs for broiler chickens.

PLoS ONE, 2020
A study evaluating apparent digestibilities of protein and amino acids and their corresponding digestion rates in four small intestinal sites in broiler chickens was completed to further investigate dietary optimisation via synchronised nutrient ...

True ileal amino acid digestibility and digestible indispensable amino acid scores (DIAASs) of cooked tropical peas

Food Research International
Tropical peas can be used as both animal feed and human food but the nutritional quality of their proteins for humans is currently poorly documented. Here, 3 varieties of tropical peas were studied at two stages of seed maturity (green or dry): Cajanus Cajan (CC), Vigna Unguiculata (VU) and Lablab Purpureus (LP).

Protein and amino acid digestibility of 15N Spirulina in rats

European Journal of Nutrition, 2020
Spirulina is often used as dietary supplement for its protein content and quality. However, in vivo data on protein digestibility are lacking. This study aims to determine nitrogen and amino acid digestibility in rats. A secondary objective was to test the effect of sonication prior to ingestion to break cell walls.Wistar rats were fed a single test ...

Utilization of ileal digestible amino acids by growing pigs: threonine [PDF]

British Journal of Nutrition, 1991
An experiment was conducted to determine the utilization of ileal digestible threonine by growing pigs. Three threonine-deficient diets (0.22 g ileal digestible threonine/MJ digestible energy (DE)) were formulated using cottonseed meal, meat-and-bone meal and soya-bean meal respectively, as the only source of threonine in the diet.

Prediction of Digestible and Metabolizable Energy Content and Standardized Ileal Amino Acid Digestibility in Wheat Shorts and Red Dog for Growing Pigs [PDF]

Asian-Australasian Journal of Animal Sciences, 2012
Two experiments were conducted to evaluate the effects of chemical composition of wheat shorts and red dog on energy and amino acid digestibility in growing pigs and to establish prediction models to estimate their digestible (DE) and metabolizable (ME ...
