Determining the digestible lysine requirement of 22 to 47 week-old Lohmann laying hens using two requirement titration methodologies
… their nutrient requirements may have changed. Lysine (Lys), is an essential and usually the second limiting amino acid (AA) in poultry diets and its requirement is especially important because it is used as the reference AA when utilizing the ideal protein concept in feed formulation. When …

Effects of nutritional plans and genetic groups on quantitative traits of pigs
… Pietrain) and nutritional plans with different digestible lysine levels (Low, Medium and High) on performance, carcass and meat quality traits; gene expression pattern of myosin heavy chain isoforms (MyHC) in Longissimus and Psoas muscles; and differential expression of lipid metabolism-related …

Evaluation of lysine and metabolizable energy in diets for broilers
… of metabolizable energy and standardized ileal digestible lysine in broiler diets, focusing on performance and body composition. Two chapters were created based on the results of the trials. In the first chapter, a study was conducted to evaluate the optimal levels of metabolizable energy and …

Lysine levels and ideal ratios of amino acids for finishing pigs
… were conducted to determine the ideal digestible lysine (Lys) requirements for early (EF = 50 to 90 kg) and late (LF = 90 to 110 kg) finishing barrows and gilts. The basal diets were reduced crude protein (CP), amino acid fortified basal diets which contained 11% and 10% CP for the EF …

Impacto da densidade nutricional sobre o desempenho de poedeiras leves
… that had varying levels were the crude protein, digestible amino acids (methionine + cystine, lysine and threonine), calcium, available phosphorus and metabolizable energy. The nutritional density affected the feed intake linearly and decreasing (P <0.0001). Egg production (P <0.0001), egg mass …

Nutritional Approaches to Increase Intramuscular Fat in Pigs
… intramuscular fat, the diet in which only the lysine was reduced by 44% of the control for either 42 or 63 d produced the largest increase in intramuscular fat. The results from this experiment suggest that dietary protein and lysine level influence the IMF content of pork. The last study was …

Variations in Amino Acid Standardized Ileal Digestibility in Soybean Meal
… may result in extensive AA damage, particularly lysine. Feeding heat damaged SBM has been proven to be an inefficient source of AA for monogastrics as they cannot be used for any metabolic function. In typical corn-soybean meal diets for pigs and poultry, lysine is the first- and second- limiting …

Effect of amino acids and vitamin D3 on performance and biological responses in poultry
… requirement of small-framed laying hens and the lysine requirement of young broilers using empirical dose-response methods. The tryptophan requirement was estimated as 155.8 mg/d for egg mass, 153.2 mg/d for egg production and 140.4 mg/d for feed conversion ratio using a linear broken line model. …

Effects of Nutritional Manipulation on Poultry under Normal and Stressful Conditions
… of laying hens in peak production and the lysine and sulfur amino acid requirements of broiler chicks under a phase feeding scenario using different models. Digestible tryptophan requirements were estimated to be 137 for egg production, 133 for egg mass, and 133 for feed efficiency using …

BEHAVIOURAL ANALYSIS OF PIGS WHEN PRESENTED WITH PEA-DIETS
The high dietary energy and acceptable digestible lysine content of field peas in comparison to soybean meal should allow for their incorporation into a wide range of diets. However, in part because of concerns over palatability, usage is limited in diets for swine. The objectives of this study …

Strategies to maximize feed quality and poultry performance
… analyses to evaluate the utilization of lysine (Experiment 1) and phosphorus (Experiment 2) in corn distiller's dried grains and solubles (DDGS) using a broiler chicken model. This research is warranted because technologies employed to produce this coproduct of corn ethanol production …

An evaluation of the effects of floor space and lysine deficient diets on the growth rate of finishing pigs and an analysis of post-restriction compensatory gain
… following an amino acid, and specifically lysine deficient diet, compensatory gain has been reported. This is where pigs previously fed a deficient diet grow faster in a recovery period (where pigs are fed a diet meeting its nutrient requirements) than pigs fed an adequate diet the entire …
