previous results indicated that performance of chicks fed a high level (10%) of poultry by-product meal(pbm) was lower than performance of chicks fed a corn-soybean meal (sbm) diet. the latter difference was hypothesized to be due to variation in digestible amino acid (aa) levels among the diets. this study evaluated diets containing pbm formulated on equivalent total aa basis vs. an equivalent...

The impact of PGF2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, Bombyx mori L. were investigated in the present experiment. The effect of PGF2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. The enhanced activity levels of amin...

the presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. to this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the research field of natural resources institute in damavand, iran. the first factor ...

A fllwrometric amino acid analyzer using fllmresramine for the assay of the full array of natural amino ac<ids including prolinc on a single column is reported. The proline determination was carried out by specific introduction of a solution of ,\‘chlorosl~ccinimide into the flow system. Single rolumn fluorometric amino acid analysis was curried out in a significantly shorter time and with a se...

the aim of this study was to investigate the processing methods of sorghum grain and diet formulation on performance and nutrients digestibility in broilers. three hundred and twenty chicks at eight day of age were allotted into eight groups of four replicate with ten chicks per replicate. this research was conducted as completely randomized design arranged in a 2 × 2 × 2 factorial experiment u...

Abstract The present study aims at the identification and investigation of fatty acid and amino acid profiles in male and female Liza aurata in the southern part of the Caspian Sea, in reproductive (autumn) and non-reproductive (spring) seasons. The results showed difference between the total fatty acids levels in the sexes. Analyses of fatty acids indicated a higher percentage of C16:0, C...

The proximate composition, amino acid and fatty acid composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker (Pseudosciaena crocea) were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but lowest lipid content. Offshore cage-cultured fish showed significantly higher content of moisture and ...
