This study was conducted to examine the effects of a combined supplementation Aspergillus awamori (AA) and lactic acid bacteria (LAB) in feed on growth egg quality. Hens (28-week old) were fed basal diet as control group; diets supplemented with 0.05% AA, 0.10% LAB, or combination AA LAB (6 birds/group) for 6 weeks. The performance birds improved by all treatments. Synergistic observed intake, production, total weight conversion (p < .05). Weights heights yolk albumin not affected treatment...

Sea buckthorn (Hippophae rhamnoides L.) has many beneficial health properties. In our previous study we showed suppression of hyperglycaemia, water intake, decreased sorbitol levels in the lens eyes after sea m(Hippophae treatment Zucker diabetic fatty rats (animal model type 2 diabetes mellitus, T2DM) with better antioxidant properties dried berries. Afterwards, decided to compare effects metformin (150 mg/kg b.wt.) and berries (500 or 1000 leaves infusion per os administration on liver...

The aim of the present work was to investigate effect Rhus coriaria L. inclusion diet on some biochemical, haematological parameters and level antioxidant status male rabbits. Adult rabbits were divided into five groups: one control (C) four experimental groups. Experimental animals received sumac per os in feed various doses (0.50%, 0.75%, 1.00% 1.50%) for 90 days. Significant increase PDWc (platelet distribution width) E3 group when compared with recorded. Sumac administration resulted...

In this study the effects of nickel (NiCl2) administered in drinking water (0.02; 0.2 and 2.0 mg NiCl2/L for 28 days) on laying hen body weight, egg production quality is reported. Growth parameters during experiment were significantly decreased mainly group with highest concentration. total dose–dependent decrease all experimental groups was found. Egg weight affected Specific not altered. Albumen albumen content concentration comparison control group. yolk analysis detected level. color a...

This study examined for the first time whether bee bread (BB, consisting of monofloral rape pollen) could alleviate lipid derangements and reduced bone quality in Zucker diabetic fatty (ZDF) rats, which are considered an appropriate animal model type 2 diabetes mellitus (T2DM) investigation. Adult ZDF rats were segregated into four groups: lean non-diabetic (L group), obese untreated (C those treated with BB at two doses (500 700 mg/kg body weight, respectively, B1 B2 groups) 10 weeks....

Citrinin (CTN) is a secondary product of fungal metabolism and contaminant various food feed materials. This mycotoxin produced by several strains belonging to the genera Penicillium, Aspergillus Monascus. In vitro in vivo studies have shown clear evidence for reproductive toxicity teratogenic, nephrotoxic, hepatotoxic embryotoxic effects citrinin. Mycotoxins can interfere cascade cell machinery thus affect cellular function. known that spread over world, however mechanism its action other...
