Effect of exogenous phytase on egg quality in laying hens

DOI: 10.15414/afz.2014.17.03.79–83Received 13. May 2014 ǀ Accepted 3. June 2014 ǀ Available online 27. August 2014An experiment was conducted to determine the effect of different levels of exogenous phytase on egg quality in laying hens fed diets with low levels of only plant original phosphorus. Twenty four Lohmann Brown hens at 31 weeks of age were housed in individual cages. In total three experiments were successively carried out with the same laying hens. In all three experiments the same diet with the same content of nutrients were always used. The control diet contained no exogenous phytase. Experimental diets differed in the level and sources of exogenous phytase. Eggs were collected daily during period of the experiment to measure egg quality. Measurement of physical parameters such as egg weight and strength of eggshell were performed daily. Shell weight and shell thickness were determined after washing and drying of shells. The shell thickness was evaluated using the micrometer. Shell proportion was calculated. The addition of phytase (150, 200, 250 and 300 FTU/kg diet) did not affect egg weight. Addition of exogenous phytase at levels 150, 200 and 250 FTU/kg had no significant effect (P>0.05) on eggshell quality. Only addition of both phytases (Natuphos and Optiphos) at the level 300 FTU to the same diet had positive effect on eggshell quality (P<0.05). Keywords: laying hens, feeds, phytase, phytate, egg quality, eggshel

Use of Common Buckwheat in the Production of Baked and Pasta Products

This chapter introduces buckwheat as a possible raw material for the production of designed foods. It includes the description of common buckwheat as a source of basic nutrients for food production and gives specificities of buckwheat as a source of biologically active substances. Processed buckwheat seeds are important from the point of view of rational nutrition as a source of energy, carbohydrates, fibre, proteins, lipids, vitamins, and minerals. Buckwheat has also other nutritional advantages, especially the interesting content of polyphenolic compounds: phenolic acids, flavonoids, especially rutin, which are characterised by high antioxidant activity. This chapter describes how buckwheat can be processed into food products and discusses the results of the application of buckwheat to bread and pasta. Moreover, it includes the results of the clinical study. Based on the identified technological and sensory properties of bread products obtained during the baking experiment, the chapter summarises recommendations on the suitable added amount of buckwheat to get satisfactory results. Concerning pasta from buckwheat, it had very good technological, nutritional, and sensory qualities. The chapter concludes that, on the basis of findings, buckwheat is a raw material suitable for the production of designed foods

Garlic (<em>Allium sativum</em> L.): Characterization of Bioactive Compounds and Related Health Benefits

Garlic (Allium sativum L.) is one of the greatest gifts of natural medicine and the oldest medicinal herbs that is cultivated all over the world. It is a widely used spice plant with well-known medicinal properties. Garlic is an important raw material of plant origin with observed and proven positive effects on the human body. A. sativum L. belongs to the most extensively studied medicinal herbs from genus Allium. In the past few decades, its biologically active compounds have been analyzed for their therapeutical properties. The most essential biologically active compound discovered in A. sativum is allicin, working synergistically with other phytochemicals in the prevention of many diseases. Preparation of garlic extractions can be done in liquid form and solid form. The composition and bioactivity of the extraction depend on the strain, age, method of preparation, and consumption method. When extracted and isolated, the bioactive compounds of garlic show a wide range of beneficial health effects: platelets inhibitory and antithrombic activities, hepatoprotective, antimicrobial, antihyperglycemic, antidiabetic, and antitumor. The present chapter describes botanical characterization of garlic, its chemical composition regarding bioactive compounds, and its health benefits

Old but still good – Comparison of malting and brewing characteristics of current and historical malting barley varieties

Historical Czech malting barley varieties Chlumecký, Stupický staročeský, Opavský Kneifel, and Diamant were tested in pilot malting and brewing tests (50 L) of 12% pale lager and compared with five Czech barley varieties recommended for the production of the beer with the protected geographical indication ‘České pivo’. The grain yield of the historical varieties (6.00–7.83 t/ha) was lower compared to the current varieties (8.23–9.39 t/ha). The malts from the historical varieties had high nitrogen content (12.45–13.89%), and low extract (75.2–78.6%, proteolytic (Kolbach index 37.4–40.9%) and cytolytic modification (friability 46.2–57.7%) was also low. Apart from lower extract yield and lower beer filtration rate, the experimental malts from the historical varieties were well processable in the pilot brewery. The sensory quality of the beers was very good (overall impression 3.3–3.8 points), fully comparable to beers made from malts from current barley varieties (3.4–3.9 points). Cluster analysis clearly differentiated the sensory profile of beers of historical and current barley varieties. The historical malting barley varieties under study may find their use mainly in the production of regional microbreweries

Von Willebrand Factor Gene Variants Associate with Herpes simplex Encephalitis

Herpes simplex encephalitis (HSE) is a rare complication of Herpes simplex virus type-1 infection. It results in severe parenchymal damage in the brain. Although viral latency in neurons is very common in the population, it remains unclear why certain individuals develop HSE. Here we explore potential host genetic variants predisposing to HSE. In order to investigate this we used a rat HSE model comparing the HSE susceptible SHR (Spontaneously Hypertensive Rats) with the asymptomatic infection of BN (Brown Norway). Notably, both strains have HSV-1 spread to the CNS at four days after infection. A genome wide linkage analysis of 29 infected HXB/BXH RILs (recombinant inbred lines-generated from the prior two strains), displayed variable susceptibility to HSE enabling the definition of a significant QTL (quantitative trait locus) named Hse6 towards the end of chromosome 4 (160.89-174Mb) containing the Vwf (von Willebrand factor) gene. This was the only gene in the QTL with both cis-regulation in the brain and included several non-synonymous SNPs (single nucleotide polymorphism). Intriguingly, in human chromosome 12 several SNPs within the intronic region between exon 43 and 44 of the VWF gene were associated with human HSE pathogenesis. In particular, rs917859 is nominally associated with an odds ratio of 1.5 (95% CI 1.11-2.02; p-value = 0.008) after genotyping in 115 HSE cases and 428 controls. Although there are possibly several genetic and environmental factors involved in development of HSE, our study identifies variants of the VWF gene as candidates for susceptibility in experimental and human HSE

Contamination of potato tubers by heavy metals and their influence on the formation of phenolic substances

Increased content of cadmium and lead in soil was manifested by their increased concentration in potato tubers in such range that contents were several times higher (Cd 0.106-0.357, Pb 0.318-0.483 mg.kg-1 FM) then the limit value. Increased content of zinc was not manifested by increased content in tubers of potatoes (Zn 4.939- 6.868 mg.kg-1 FM). Content of total phenolics (TP) in potato samples of Hontiansky and Banskoštiavnický region was in the range of 263.59-920.38 mg.kg-1 of dry material. Exceeded content of cadmium and lead in potato tubers had statistically significant effect on total phenol producing, but on the other hand relation between contents of Zn and TP in potato tubers was not statistically confirmed. Also positive correlation between TP and antioxidant activity contents was statistically confirmed
