Amino acids in poultry nutrition
Adequate provision of dietary amino acids is required to maintain normal immunocompetence and protection of the host from some diseases in all species (Beski et al. 2015). Therefore, the development of immune function in poultry will be promoted if they receive sufficient amino acids in their diets. The essential amino acids for poultry are arginine, glycine, histidine, leucine, isoleucine, lysine, methionine, cystine, phenylalanine, threonine, tryptophan, and valine. Out of these, the ones critical in practical diets are arginine, lysine, methionine, cystine and tryptophan.
Protein quality of the soybean meal is the result of amino acid present in the meal and the portion in the bioavailable form to the animals. While intending to utilize the same for monogastric animals, it has to be properly heat processed so as to minimize the anti nutritional effect and thereby increasing the digestibility of amino acids present in the meal. At the same time as known to everyone, it should not be over processed which will decrease the concentration and digestibility of...

Introduction The poultry industry has experienced unprecedented growth in the past 70 years due to improved genetics, nutrition, housing, water quality and veterinary care driven by post-WWII consumer demands (Havenstein, et al., 2003). Modern-day poultry efficiently convert feed to meat and eggs, but genetic selection for improved performance may have inadvertently selected for a negative correlative response to other traits such as immune function (Cheema et al., 2003). The reader...

Poultry scientists find that Asp+Asn, Glu, or Glu+Gln supplementation can partly make up for low crude protein levels in male broiler chicken diets
A new study led by poultry scientists at the University of Hohenheim suggests it is possible to reduce crude protein in broiler diets while still encouraging bird growth—as long as birds receive supplementation with several “nonessential” amino...

The objective of this study was to determine the relationship between in vivo amino acid digestibility and protease inhibitors in commercial soybean meal (CSBM). A total of 12 CSBM samples were analyzed for: (1) trypsin inhibitor activity (TIA) utilizing the new official AOCS method (Ba 12a-2020). (2) chymotrypsin inhibitor activity (CIA) by the latest optimized method of Liu (2022. J. Food Sci. https://doi.org//10.1111/17503841.16141), and (3) in vivo amino acid (AA) digestibility...

Introduction Coccidiosis is the most common parasitic disease caused by Eimeria spp., leading to over $14 billion economic loss worldwide annually (Blake et al., 2020). The most prevalent Eimeria spp. in poultry include E. tenella, E. maxima, E. acervulina, E. brunetti, E. necatrix, E. praecox, and E. mitis and have different level of pathogenicity and specific infection sites in the intestine (Cervantes et al., 2020). Eimeria spp. invade intestinal epithelial tissues and induce...

Introduction: Betaine has been known as a functional nutrient widely used in animal nutrition during the last decade. It’s the trimethyl derivative of glycine, and is present in many plants and animal tissues such as aquatic invertebrates and sugar beets. As a feed additive, betaine is commonly used as anhydrous, monohydrate, and betaine hydrochloride. According to the latest research, the nutritional properties of betaine HCL is equal to anhydrous while offering...

Introduction Over the years, nutritionists have studied several ways to determine the ideal dietary supply of essential amino acids to optimize poultry performance. However, considering only performance objectives without taking into account economic factors may not reflect maximum profitability, since optimizing performance is not always viable (Pack et al., 2003). An economic approach to determine amino acid supply by minimizing feeding costs and maximizing revenues was...

It has been proposed that the metabolic energy requirements of free-ranging hens are up to 15% higher compared to caged hens due to the increased metabolic activity required for locomotion and thermoregulation (GfE 1999; Tiller 2001; Aerni et al. 2005). The aim of the study was to investigate the impact of various feed strategies on laying performance and egg quality of free-range laying hens. A total of 9,375 hens, placed amongst 5 flocks of 40,000 hens each were selected according to their...

1. Introduction The mucosal lining of the small intestine is a highly functional epithelium comprised of absorptive, secretive and sensory cells, which are constantly renewed by multipotent intestinal stem cells (ISC). ISC reside within crypts, and constantly proliferate for self-renewal and generation of progenitor cells, which differentiate into the functional cells that line lumen-facing villi (Carulli et al., 2014; Potten and Loeffler, 1990). Compartmentalization of the...

Hypothesis Guanidinoacetic acid (GAA) is synthesized in the liver and kidneys from arginine (Arg) and glycine (Gly) and subsequently methylated by S-adenosylmethione to creatine (2). Heat-stressed birds respond to the presence of higher uric acid concentration and changes in electrolyte balance by increasing the usage of osmoprotectants. These osmolytes are viable endogenous precursors for Gly (3). On the other hand, high supplemental lysine level on modern genetic broiler...

INTRODUCTION Least cost feed formulation relies on the assumption of additivity of digestible nutrients from the contributing ingredients. It is generally accepted that assessment of the nutritional value of individual raw materials underestimates their eventual contribution in a complex diet because of the often-substantial influence of endogenous loss. The premise is that a proportion of nutrients that leave the terminal ileum are inevitable (or “basal”) losses and...

1 INTRODUCTION During the last decades, the productivity of laying hens has improved significantly, with higher number of eggs produced over the laying cycle and higher efficiency to utilize feed nutrients. This increase in productivity implies in a change in the requirements, and consequently, these hens become more demanding in nutrients, mainly amino acids (Elliot, 2008). Optimization of protein supply by understanding the amino acid needs of these hens requires a thorough...
