1. Introduction The best strategy to optimize production and reproduction in poultry species while mitigating the harmful effects of environmental conditions is proper nutrition 1,2,3 . One of the pillars of nutrition is the use of amino acids in poultry diets, among which Methionine (Met) represents the first limiting amino acid in broilers. As Bunchasak 4 reported, Met can act as an amino acid in the synthesis of protein and polyamine, a sulfur donor, a...

I. Introduction Guanidino acetic acid (GAA) is a naturally occurring metabolite which is synthesized in the kidney by L-arginine-glycine amidinotransferase (AGAT) using glycine and arginine (Arg) as substrate (Brosnan et al. 2009). Then, GAA is methylated to creatine in the liver using GAA N-methyltransferase (GAMT). Feeding GAA to humans and animals increases creatine in blood and muscle tissues (Ostoic et al. 2013; DeGroot et al. 2018). High creatine in blood has an inhibitory...

INTRODUCTION It is imperative to identify factors that inhibit the digestibility of nutrients for successful commercial poultry production. The non-starch polysaccharides (NSP) like substances of hemicellulose, cellulose, and pectin can reduce nutrient digestibility in poultry (Choct, 1999). Among the NSP, β-mannans are a group of hemicelluloses, which are present in many ingredients used for poultry feeds like soybean and other leguminous seeds. It occurs in the forms of...

1. Introduction As feed grade amino acids are commercialized at prices that are economically feasible for including in industry poultry diets, nutritionists are able to better supply diets containing amino acid profiles more closely representing ideal amino acid profiles (Baker, 1997). Refinement of dietary amino acid profiles allows for reductions in crude protein (CP), inclusion levels of protein-rich ingredients in the diet and nitrogen excretion in broiler chickens (Kidd et...

INTRODUCTION Conventional broiler production is dependent on maize as a source of energy and soybean meal as a source of protein. Nutrient digestibility of plant-based feeds in poultry is limited by the proportion of their components for which there are no corresponding endogenous enzyme secretions. These components include non-starch polysaccharides (NSPs) that are present within the cell walls of maize and soybean meal 1,2 . The NSPs are either indigestible or of very...

I. Introduction The development of reduced-CP diets in broiler chickens is gaining more interest as it would drastically lessen the dependence on imported soybean meal which is strategically important for non-soybean producing regions such as Australia and Europe. Modest reductions in CP are already being realised by inclusions of unbound (synthetic or crystalline) methionine, lysine and threonine, which have been routinely included in poultry diets for decades (Kidd et al., 2013)....

Introduction The basic nutrients that poultry birds require for maintenance, growth and reproduction include carbohydrates, proteins, minerals and vitamins. The energy and protein are the most important as well as expensive nutrients in poultry diet. Maize and soyabean meal are the conventional feed ingredients commonly used in poultry industry because of its nutrients composition and digestibility. In recent year skyrocketing prices of conventional protein sources like soyabean...

Evaluation of true ileal digestible energy, as a potential energy system for application in broiler feed formulations, requires accurate estimation of the ileal endogenous energy losses (IEEL). The IEEL estimates can be influenced by several factors including bird age and dietary cellulose levels (Khalil et al., 2020). Two experiments were conducted to investigate the influence of age and dietary cellulose levels on the IEEL estimates in (Ross 308) broiler chickens. Titanium dioxide (5.0...

I Introduction In recent years, based on ideal amino acids profile, a moderate reduction in dietary CP, 20 to 30 g/kg, has been reported to maintain broiler chicken performance and processing yields. However, further reduction of CP more than 30 g/kg has been shown to compromise bird performance and increase adipose fat accumulation (Kidd et al, 2021). These reduced CP levels are usually achieved by increasing feed grains such as wheat inclusion at the expense of soybean meal,...

I Introduction The development of reduced-crude protein (CP) diets for broiler chickens holds several potential advantages including reduced dependency on imported soybean meal by the Australian chicken-meat industry. Typically, reduced-CP diets contain less soybean meal but more feed grain (and starch) and more synthetic/crystalline amino acids. However, reducing dietary CP from 200 to 150 g/kg in isoenergetic diets has been shown to depress body weight gain, impair food conversion...

Broiler chickens grow rapidly with nutrient requirements changing daily. However, broilers are fed 3-5 diet stages throughout their growth, meaning nutrients are under- and over-supplied throughout production (Kleyn, 2013). Thus, blending rations on a daily basis to meet the daily energy and lysine requirements may improve the efficiency and reduce the coefficient of variation (CV) in broiler flocks. Therefore, the present study evaluates precision feeding regimens for broiler...

INTRODUCTION Providing adequate quantities of animal protein to meet the demands of a continuously growing population requires that livestock producers must increase the production efficiency of farm animals. This can be achieved through improved genetics, management, and nutrition. Furthermore, feed ingredient prices continue to increase, resulting in minimizing the profit for the producers and forcing them to seek cheaper alternative ingredients, typically of lower quality and...

1. Introduction Exogenous xylanase (XYL) has been routinely used in poultry diets to hydrolyse nonstarch polysaccharides (NSP) and improve the feeding quality of fibre-rich diets, including wheat [1]. The beneficial effect of XYL in wheat-based diets is mainly attributed to the reduction of digesta viscosity, improving digestion and absorption of nutrients, dietary energy availability and subsequent growth performance of broilers [2,3]. In layers, XYL has been assessed as...
