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 ...

Heavy broilers with high breast meat yield are more susceptible to heat stress. Under high relative humidity, indoor air velocity (AV) becomes critical to offer optimal environmental conditions for growth and health. Four experiments were conducted under southeastern summer conditions to evaluate the effects of AV treatments (High vs. Low) on live performance, cut-up yields, meat quality and welfa ...

Adequate pullet nutrition is essential to obtain the BW and development suitable for reproduction. An 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 on BW, abdominal fat deposition and development. A total of 1,360 Cobb-500 slow-feathering (SF) pullets were placed in 16 floor pens (85/p ...

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 th ...
