INTRODUCTION
Like other animal production systems, aquaculture has developed into a highly globalized trade-dependent industry, therefore as global fish farming continues to increase, the need for formulating nutritionally balanced and cost-effective diets with high-quality protein source is important (Furuya et al., 2010). In fact, nutritional value of protein in the diet for fish is influe ...

Iván Camilo Ospina-Rojas, good article, with an enlightening focus. I take advantage of the material presented here, which somehow comes to consolidate some information that we publish, right here at ENGORMIX with the title; Digestible lysine levels obtained by two methods of formulation of diets for 22-to-42-day-old broilers, with a focus on differentiating diets with or without the use of ...

I might ask the person in charge of your region about the Arg in feed grade. Pls, feel free to contact me (camilo.ospina@cj.net) to keep you updated. When there is a low Arg/Lys ratio is recommended to avoid high Cl levels, which can increase arginase activity increasing the Arg degradation. As Arg cannot be synthesized by poultry (essential AA), I don't recommend using a low Arg/Lys ratio. The pe ...

George Entz, thanks for your question and sorry for my late response. Recently, it was launched Arg commercially available for feed grade. That´s why I don't see any reason to work with low Arg levels even more in challenged or vaccinated birds. Arginine supplementation has shown to increase antibody titer against some diseases and enhance the antigen-specif immune response. Also, supplement ...

Juarez Donzele Thanks for your comment.
This is one of the four abstracts presented on this topic a year ago.
The full papers have been submitted for publication.
I would recommend you read all the information prior to making conclusions based on a 2,300 character abstract.
I did not make this publication in Engormix. This is public material that Engormix found on the web based on
material ...

Near infrared reflectance spectroscopy (NIRS) is nowadays a common tool to analyze the nutritional content of feedstuffs. Corn hybrids and drying temperatures could affect the nutritional value of the grain. It is important to determine if these factors are detected by NIR. Two corn hybrids (Dekalb 68-05 and Dekalb 65-20) varying in kernel hardness (average and hard respectively) were dried at thr ...

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 (8 ...

1. Introduction
Better growth, economy and environment-friendly commercial broiler production is limited to the right amount of available amino acids for efficient utilization in animal body. All of the crystalline amino acids supplemented in commercial poultry production are in their natural (L-isomer) form except methionine (Met), which may be utilized in its synthetic (D- and L-isomers) form i ...
