The objective of this study was to evaluate the effects of dietary supplementation of barley malt extract and barley malt vinegar on growth performance, jejunal morphology and meat quality of broilers. A total of 600 day-old chicks were allocated to four dietary treatments to evaluate the effect of dietary inclusion of 0.2% barley malt extract alone or along with 0.4 or 0.8% of malt vinegar as ...

the present study aimed to investigate protective effects of dietary cinnamon essential oil supplementation on decreasing the toxicity of aflatoxin b1 to rainbow trout fingerlings regarding hematological indices, serum biochemistry and liver histopathology. fish were randomly exposed to six distinct treatments composed of different combinations of three dietary aflatoxin (0, 25 and 50 ppb) and ...

Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...

A male cohort from New Zealand has previously shown variability in Selenium (Se) supplementation effects on measured biomarkers. The current analysis is to understand the reasons for variability of the H₂O₂-induced DNA damage recorded after Se supplementation. We have looked at the variation of demographic, lifestyle, medication, genetic and dietary factors and biomarkers measured at baseline a...

background: studies have shown that zinc and selenium deficiency is common in nonalcoholic fatty liver disease (nafld). however, the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld are not clear enough. the aim of this study was to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld prognos...

The studies of dietary fish oil supplementation in healthy volunteers demonstrate a significant increase in neutrophil EPA content, a concomitant reduction in neutrophil AA content, and suppression of neutrophil LTB4 synthesis by supplementation with dietary fish oil containing approximately 3-4 g EPA daily for a minimum of 4 weeks. Suppression of neutrophil chemotactic responsiveness to LTB4 a...

The effect of dietary riboflavin (B2) supplementation and selenium (Se) source on the performance and Se metabolism of weanling pigs was studied. Pigs fed a B2-supplemented (10 mg/kg) casein-glucose diet for 18 d gained faster than pigs fed the B2-unsupplemented diet. Percentage active erythrocyte glutathione reductase (GR) declined rapidly when pigs were placed on the B2-unsupplemented diet an...
