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.

The objectives of the trial described in the article were (i) to compare the effects of OH-Methionine compared to DL-Methionine on growth performance and feather growth of Cherry Valley ducks fed from 0 to 42 days and (ii) to determine the bio-efficacy of OH-Methionine (OH-Met) relative to DL-Methionine (DL-Met). The trial was published by Zhao et al.2018 in Poultry Science: Efficacy of 2-hydroxy-4-methylthiobutanoic acid compared to DL-Methionine on growth performance, carcass...

Amino acid pullet nutrition affects growth and development and it is important to evaluate potential effects on egg traits. One experiment was conducted to determine the effects of four amino acid (AA) dietary levels fed to broiler breeder pullets during the rearing phase from 5 to 24wk of age on egg characteristics. A total of 1,360 Cobb-500 slow-feathering pullets were placed in 16 floor pens (85/pen). Up to 4wk all pullets were fed one starter diet in crumbles and after 29d of age fed...

INTRODUCTION Consumer demand for eggs in North America has been steadily increasing, with retail growth of 6% in 2018 in Canada, up from the 4.1% growth seen in 2017 (Egg Farmers of Canada, 2017, 2018). In the United States, 2018 per capita egg consumption increased by 2.1% over 2017 (USDA, 2019). It is therefore critical to establish suitable nutritional and management strategies that accommodate these increased production goals, while accounting for the economic, social, and...

INTRODUCTION Aflatoxins, the natural contaminants of feedstuffs, are toxic metabolites produced primarily by Aspergillus flavus and Aspergillus parasiticus. Aflatoxins may cause serious economic losses in the poultry industry because they prevent birds from achieving optimum body weight gains (Khatke et al., 2012; Oguz and Kurtoglu, 2000) Small amounts of aflatoxin B 1 may cause reduction in economic parameters, hatchability and also cause increased susceptibility to...

The 50-year historical review of soybean meal (SBM ) published in Feedstuffs in 1970 by Dr. J.W. Hayward highlighted many of the pertinent advancements concerned with animal nutrition, product development and promotional aspects of U.S. SBM. In fact, 1920 marked not only the beginning of the industrial production of soybean oil and SBM in the U.S., but also the year that the American Soybean Assn. was founded (Hymowitz, 1990). The use of SBM at the time this 50-year review was published was...

Introduction Globally, feeding cost and the price of poultry product have recently increased due to increasing competition between human and animals for the same feed resources. Agriculture by-products are valuable feedstuffs that can be used in animal nutrition (Al-Harthi et al. 2018a, 2018b). In animal nutrition feed processing and feed additives as well have been used for improving the feeding values of feeds particularly of agricultural byproducts (Dozier et al. 2010;...

It’s all about performance. Best quality, best handling. It's about science. Particularly for use in monogastrics. MetAMINO® ensures the adequate supply of sulfur amino acids, especially of the essential methionine. Because of methionine being first-limiting in typical poultry diets its use has been well established for many years. Additionally, diets for piglets and growing pigs can show a considerable defi ciency in methionine, especially when formulated to achieve low nitrogen excretion for...

Employment of new nutritional strategies to limit the impact of the livestock production on the environment, have become an important task. Optimization in the feed formulation lowering the crude protein content, for the so-called N-reduced feeding, is one of the best possible nutritional strategies for environment...

Minerals play an important role in regular dietary requirements of animal feed and are essential for growth, reproduction and milk production. Essential minerals are destroyed during the digestion process due to interactions with other components of feed. Use of Organic Trace Minerals in the feed is the optimal way to ensure protection and absorption of minerals through the intestinal walls into the blood stream and reaching various organs to perform...

Trypsin inhibitor (TI) analysis is considered the best in vitro method to predict anti-nutritional factors in soybean products. TI in solvent-extracted soybean meal (SBM) can vary according to genetics, under-processing, over-processing, etc, and high levels are associated to outbreaks of feed passage with consequent decrease in broiler performance. The objectives of the study were: 1) determine the impact of Brazilian...
