The present study was carried out to determine the effects of fenugreek powder (FP) and extract (FE) on performance, egg quality, blood parameters and immune responses of laying hens. One-hundred and fifty Leghorn laying hens were used in a completely randomized design with five treatments and five replicates for eight weeks. Treatments were various levels of FP and FE including zero (control; ...

Objective: This study was conducted to evaluate the effects of different proportions of marshmallow extract (Althaea officinalis L.) on growth performance and carcass composition of common carp (Cyprinus carpio). Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...

this study surveys on the effects of l-lysine and methionon amino acids on growth performance, survival rate and body composition of rainbow trout (oncorhynchus mykiss). fish with initial average weight 105.23 +  6.33 g in 5 treatments fed with different levels of lysine (1 and 3 %) and methionine ( 1 and 2%) for 8 weeks. the results showed that the treatment which fed 2 % methionine had the be...

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

Addressing the question ‘why productivity growth rates differ between countries’ from a dis-equilibrium standpoint, in the present paper it is explored the possibility to compound in a single formalization two different but complementary theories of technical change and macroeconomic growth, that is the Kaldorian idea of cumulative causation and the technology-gap approach to economic growth. I...

feed restriction strategies are proven to be effective in increasing the growth performance and carcass parameters of broiler chickens. the objective of the present experiment was to evaluate the effects of feedremoval for three hour time periodon growth performance and carcass parameters of relatively older male broiler chickens. twenty days old male broiler chickens (n=80) were allocated into...
