The Influence of Abomasal Supplements of Some Amino Acids and Sulphur-containing Compounds on Wool Growth Rate

Protein and sulphur amino acid nutrition of hair fibre-producing Angora and Cashmere goats

The results from a number of studies are presented which investigated responses in fibre production of British Cashmere and Angora goats to variation in protein and sulphur amino acid nutrition under conditions of active fibre growth. Requirements for amino acids were considered in the context of the concentration of amino acids, including cysteine and methionine, in rumen microbial protein and...

اثر اسیدهای آمینه بر رشد میکروسپوریوم کانیس و ترایکوفایتون شوئن‌لاینی

Background: Amino acids have different effects on the growth of some dermatophytes. Some may encourage growth, while others inhibit it. The concentrations of some amino acids also are an important factor for their effect. To investigate the effects of amino acids on the growth of dermatophytes, the dermatophytes Trichophyton schoenleinii and Microsporum canis, obtained from Iran. Methods: In t...

Response of layers fed on diets dificient in protein and sulphur amino acids supplemented with lipid

Effects of branched-chain amino acid deficiency in diets on growth factors, pancreatic enzymes activity and whole body proximate of Sobaity seabream juvenile (Sparidentex hasta)

On the current study the effects of reducing branched-chain amino acids (BCAA) in diets of Sobaity sea bream in a constant level (40%) on growth and nutritional indices, pancreatic enzymes activity, whole body chemical proximate and amino acids, was assessed. This experiment was conducted in Marine Fish Research Station of Imam Khomeini harbor during July and August of 2014. For these purposes,...

Effects of amino acids on the growth of an anaerobic rumen fungus Neocallimastix sp N 13.

The amino acid requirements of Neocallimastix sp N 13 isolated from sheep rumen were studied using supplements containing either ten essential amino acids (10 EAA) or eight nonessential amino acids (8 NEAA), or both (18 AA). Although the fungus could grow in a medium containing ammonium sulphate as the sole source of nitrogen, amino acid supplements, especially 18 AA, greatly stimulated its gro...
