a study was carried out to examine the effect of different levels of herbal methionine and dl-methionine on the growth performance and immunocompetence of broiler chickens fed on a corn-soybean meal diet. a total of 225 old male broiler chickens (ross 308) were used as experimental samples in a completely randomized design. they were randomly assigned to 9 treatments each of 5 replicates in eve...

a study was carried out to investigate the effects of organic acid mixture as well as two methionine supplements on performance, carcass characteristics and weight of gastrointestinal tract in broiler chickens. six hundred unsexed day-old ross 308 broiler chicks were utilized in a factorial arrangement of treatments (3×2) based on completely randomized design (crd) of 4 replicates of 25 chicks ...

Abstract The amino acid l -methionine is an essential and commonly used as a feed supplement in terrestrial animals. It less suitable for marine organisms because it readily excreted. also highly water soluble this results loss of the eutrophication water. To address these problems, dipeptide dl -methionyl- (trade name: AQUAVI Met-Met) has been developed dedicated methionine source aquaculture....

The objective of this research was to determine the effect different starters consisted dried whey and soy proteins with low anti-nutritive factors (ANFs) + amino acids (lysine methionine) on body measurements, biochemical parameters, feed consumption early-weaned female Holstein calves. Based starter, calves were divided into four groups: i) control (control starter), ii) E1 (starter added dry...

Two 28-d randomized complete block design experiments were conducted to evaluate the effects of concentrations and sources of Zn on growth performance of nursery pigs. Seven stations participated in Exp. 1, which evaluated the efficacy of replacing 2,500 ppm of Zn from ZnO with 125, 250, or 500 ppm of Zn from Zn methionine. A control diet with 125 ppm of supplemental Zn was included at all stat...
