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.
Evonik’s animal feed solutions quench livestock thirst and reduce the environmental impact of meat and dairy production WHITEPAPER According to the UN, four billion people experience severe water scarcity for at least a month a year – and due to our unsustainable use of freshwater and other resources, water stress will increase further. One of the drivers is water-intensive meat and dairy production, which accounts for roughly a quarter of the global water...

Protein is the second most expensive nutrient in animal feed formulation, after energy. Diets which have excess crude protein can overload the gastrointestinal tract with excess amino acids and undigested protein (Apajalahti and Vienola, 2016), resulting in impaired feed efficiency, health and welfare issues as well as negative environmental impacts via excess nitrogen excretion. Reducing dietary protein in poultry diets can help to mitigate some of these negative effects. In poultry diets,...

INTRODUCTION A healthy gut can help birds to gain optimum growth performance because gastrointestinal tract (GI) is meant for digestion/absorption of nutrients and immune response. The mucosal membrane of the intestine serves as a barrier between luminal digesta and tissues and requires a dynamic balance between different components of gut like epithelial cells, microbiome, and immune system cells for proper functioning. One of the most important components that affect...

1. Introduction Plant compounds that possess antioxidant and antimicrobial properties have the potential to replace antibiotic growth promoters in poultry diets, especially since in most countries, the use of in-feed antibiotics has been banned [1]. The idea behind this intervention is to avoid antimicrobial resistance and residual effects posed by the systematic use of antibiotics, but to maintain high performance, bird health and to produce safe food [2]. Globally, many...

INTRODUCTION There has been a substantial global expansion in egg production by the layer industry as the volume of egg production has increased by 119% (35.5 vs. 76.8 million tonnes) from 1990 to 2018 (http://www.fao.org) (Food and Agricultural Organization of the United Nations, 2018). This growth represents an average annual increase of 2.84%. China produced 458 billion eggs in 2018, and the USA produced 109 billion eggs in 2018 (https://www.statista.com). China had the...

1. Introduction The poultry industry has undergone many changes in recent years in response to increasing demand for both meat and eggs [1]. As a result, nutritionists and geneticists have performed extensive work to improve bird weight, maturity time, growth rate, feed efficiency, and size of breast meat [1]. These changes have affected muscle formation and the chemistry of the modern broiler meat and consequently meat quality traits. Consumers demand high-quality meat, which...

1. Introduction The conversion of dietary protein and amino acids into the protein of chicken-meat is indeed a dynamic process. Quite typically, broiler chickens attain a live weight of 2.918 kg at 42 days post-hatch and a carcass weight of 2.151 kg following processing. This translates to 376 g of carcass protein as a Ross 308 broiler carcass contains 175 g/kg protein [1]. Broiler chickens consume 4.702 kg of feed over 42 days with dietary protein contents declining from 230 to...

Yangzhou University scientists examine meat quality from every angle
Duck meat is prized for its delicate flavor and juicy texture, as well as its notable protein content, polyunsaturated fatty acids, vitamins and minerals. In fact, duck meat is rising in popularity, especially in China.
The challenge is to get ducks to market quickly without compromising meat quality. In China, which produces 85...

INTRODUCTION Met is the first-limiting amino acid in corn-soybean based diet of poultry and plays an important role for growth, and egg production, but excess Met supplementation can be toxic for poultry. Besides carcass yield and quality, feather growth is especially important economic trait for meat duck production. Optimum feathering is considered crucial in modern broiler production due to demands for high standards of carcass quality (Lopez-Coello, 2003). Poor feathering...

I. INTRODUCTION The concept of “fast” and “slow” proteins in human nutrition was enunciated by Beaufrère et al. (2000) and consideration has been given to protein and starch digestive dynamics in poultry by Liu and Selle (2015). However, the digestion rate of protein has a greater bearing on broiler growth performance than that of starch (Liu et al. 2014). Thus, the objective of this experiment was to compare the effects of ten nutritionally...
