Explore all the information onAmino 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.
Introduction Over the years, animal nutritionists have developed alterations in the quality of diets intended for broilers aiming to increasingly adapt these diets to meet the nutritional requirements of these birds. Studies on the protein nutrition of broilers have considered the use of digestible amino acids in the formulation of diets, which makes it possible to reduce the amount of dietary protein and improve the adjustment between amino acids, thus contributing to...
DESCRIPTION OF PROBLEM Phytase has been regularly incorporated into commercial poultry diets due to its relatively low cost and effectiveness at hydrolyzing phytate (IP6; myo-inositol 1, 2, 3, 4, 5, 6-hexakis dihydrogen phosphate; Bedford and Cowieson, 2009). Dephosphorylation through phytase supplementation is needed for birds to access this source of P and also to prevent the chelation of IP6 with other nutrients such as amino acids and minerals (Nelson, 1967; Ravindran et...
A previous study highlighted differences between a low protein (LP) diet and a higher concentration of amino acids (AA) for intestinal permeability and performance (Barekatain et al. 2018). It is hypothesised that individual AA such as glycine (Gly), glutamine (Gln) and arginine (Arg) may improve gut health and barrier function of birds fed LP diets. To test this hypothesis in a broiler study, two basal diets were prepared as follows: 1) a standard diet (SD) containing 225 g/kg crude protein...
METHPLUS® is a nutraceutical product that acts in feeds as adjuvant to synthetic methionine (from Latin, adiuvare: to aid). Thanks to its ingredients based on plant extracts, seaweed and legume, helps to enhance remethylating path of the methionine cycle. METHPLUS® was developed thanks to European funds, over a period of 3 years, and its effectiveness has been demonstrated in the field in numerous countries with different diets, different climatic factors and management,...
I. INTRODUCTION Diet cost represents approximately 60 to 70% of total live production cost of broilers (Donohue and Cunningham, 2009). Price volatility of AA-contributing ingredients may largely impact diet cost and subsequently live production cost. Soybean meal has been considered the “golden standard” intact source of AA due to its excellent AA profile for poultry. Price volatility of soybean meal has created interest in utilizing alternative intact AA sources...
I. INTRODUCTION The global supply of poultry products will need to double by 2050 if we are to meet the aspiration of all people to be food secure. We will need to produce more poultry meat in the face of changing consumer perceptions and constrained resources. Consumers expect this to be achieved in a sustainable manner. The industry has the skills to achieve this. Genotypes continue to improve; production methods and business models are evolving; and we have enhanced our...
Poultry is a homothermal animal, and its body covers with feathers to increase its cold resistance. However, Taiwan is an island that lies in the tropic of cancer, and the general climate is marine tropical. During summer, this mechanism is adverse to heat dissipation and causes heat stress. Heat stress is a familiar stress effect that will affect animals’ growth performance, productivity, and health. Heat stress affects livestock production results in increased demand for net...
Life Rainbow Biotech has developed a liquid type nutrition supplement – Gano-met® provides broiler and layer essential nutrition instantly and stress relief. Gano-met® contains extracted Ganoderma lucidum and methionine hydroxy analog (MHA), riches in active compounds such as required amino acid, polysaccharides, and triterpenoids. Ganoderma lucidum is an edible traditional medicine mushroom, also known as “Lingzhi”(Chinese) and...
INTRODUCTION Poultry population in Nigeria is put at 140 million and it is a major contributor to the economy (FMAWR, 2008). There is also a consistent rise in intensification of production and a growth rate of 306.6% between 1999 and 2004 (Glipha, 2007). The importance of these statistics is that Nigeria inadvertently contributes to environmental issues currently debated world - wide vix air and water pollution, greenhouse gas (GHG) emission, climate change etc. Owing to the...
Introduction Precision Animal Nutrition is the effective use of available feed resources in order to maximize the response of animals to nutrients. It is an ideal method to improve the productivity of animals in developing countries in view of inadequate...
1. Introduction In hot climates, the growth of broilers is usually slow, as high temperature adversely affects feed intake, and high-protein diets, used to sustain animal growth, may impair broiler tolerance to heat stress due to the high heat increment induced by protein metabolism [1,2]. Decreasing dietary protein levels of broiler diets could be a good strategy, but the amino acid requirements for broiler chicks must be satisfied by supplementing synthetic amino acids to the...

A study published in 2003 comparing the nutrition and genetics of broilers from 1957 to a commercially available broiler strain estimated that within less than 50 years of development, broilers were reared to maturation in a third of the time (Havenstein et al., 2003). This shows clear evidence that improvements in genetics, nutrition and management of rearing meat producing chickens has continually improved the growth rate of birds. However, the effects of rapid growth rate on immune...
FLORFENICOL On October 21, the average market price was 440 yuan/kg, an increase of 0.69% MoM, a three-month high, but slightly lower than the same period last year, a YoY decrease of 2.21%. After...
Introduction Dietary arginine supplementation higher than the recommended levels was shown to improve broiler performance (Murakami et al. 2012; Xu et al., 2018; Zampiga et al., 2018). It suggests that arginine levels needed for maximum performance could be higher in modern broilers, which is probably related to the several functions of arginine on animal metabolism. Besides, arginine enhances the protein synthesis via the activation of the mTOR signaling pathway (Yao et al.,...
Introduction Protein is a major and expensive component of animal feed, accounting for about 20% of the total dry matter content of swine and poultry diets. Soybean meal is the leading source of feed protein [ 1 ]. In the gut, protein is hydrolyzed by endogenous proteases, principally pepsin (EC 3.4.23.1), trypsin (EC 3.4.21.4) and...
