This study aims to evaluate the potential of animal proteins of freeze-dried whey as a component for pasta production and its effect on the pasta qualities and consumer acceptance. Sweet whey was freeze-dried, then directly incorporated to pasta at a 20% level. Two pasta types (pasta non-enriched vs. enriched with whey powder) were manufactured following a small-scale pilot procedure, and then evaluated for their physicochemical and sensory qualities. Results of all analyses (whey, semolina and pasta) met the standards according to international legislation; however, the characteristics of enriched pasta differed. Whey addition significantly increased ash, proteins content, optimal cooking time and water uptake (P < 0.05); it significantly decreased moisture levels, colour parameters (CIE system: a* redness, b* yellowness) and the swelling index (P < 0.05). Sensory analysis revealed that overall sensory and product quality of enriched pasta was not affected by whey fortification and it was found acceptable by panelists. This study points out that whey powder could be used for the functional pasta production to increase proteins levels.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47269680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, many people tend to gluten-free food without health and medical reasons. Many gluten-free products are nutritionally poorer than gluten-containing analogues. Although in many cases gluten-free products are nutritionally rich (either naturally or as a result of fortification), the bioavailability of nutrients is limited. The study focused on the influence of a six-week consumption of gluten-free bread and bakery products on mineral status in thirty healthy people without coeliac disease and the impacts eight weeks after the end of the consumption. Since the recommended daily intake for phosphorus, calcium, magnesium and iron was satisfied at only 84–88% for our volunteers, we consider the increase in the average serum levels of the monitored parameters to be positive (except for calcium). The six-week consumption of gluten-free bakery products had a positive effect on the mineral status of the monitored group of healthy consumers. We found a significant increase in phosphorus (P < 0.001) and magnesium (P < 0.01) levels, a certain increase in iron (P > 0.05), whereas the level of calcium insignificantly lowered (P > 0.05).","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43297218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four rams with initial body weight of 18.5 ± 1.49 kg were randomly allocated to four treatments containing ad libitum natural grass hay alone (T1), hay + 150 g SPL (T2), hay + 300 g SPL (T3) and hay + 450 g SPL (T4) on as fed basis. Results indicated that dry matter (DM), organic matter (OM) and crude protein (CP) in-takes increased (P < 0.001) with increasing levels of SPL. Sheep fed with T2, T3 and T4 diets gained 55.1, 52.6 and 66.5 g per head per day, respectively, while the gain of non-supplemented sheep (9.19 g per head per day) differed (P < 0.05). Digestibility of DM, OM, and CP was higher (P < 0.01) for all supplemented sheep compared with the control. The CP digestibility and N retention were negative in non-supplemented sheep. Urinary N excretion decreased (P < 0.001) with the increasing levels of SPL supplementation. The N retention improved with the increasing levels of SPL and was the highest (P < 0.001) in sheep fed with T4 diet and the lowest in non-supplemented sheep. In conclusion, supplementing a basal diet of natural grass hay with SPL considerably improved the average daily gain, OM and CP digestibility and N retention.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45323001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were obtained through a survey and concerned the health of 241 individuals of giant dog breeds held in the Czech Republic. Evaluated items involved an average lifespan, an average lifespan per gender, cause of death, reasons for euthanasia, cause of mortality (especially in selected Mastiff type breeds), life expectancy per breed and incidence of diseases among giant breeds during the lifetime. The average lifespan in giant breed dogs was found to be 7.60 years. A significant difference (P ˂ 0.05) was found between life expectancies in males and females, with female dogs reaching 1.42 year higher age (8.10 years) than males (6.68 years). The most common cause of spontaneous death among giant breeds was gastric dilatation and torsion (28% of dogs) and for euthanasia osteosarcoma (38% of dogs). The cause of mortality especially in selected Mastiff type breeds of dogs was gastric dilatation and torsion (30% of dogs).

We defined the machines performance indicators significantly affecting the plant potential release not considered previously. The study results were obtained via the soil tilling depth regulation by the disking speed, the change of an incidence angle of the working batteries, and by the use of the additional load mounted on the machine frame. The article presents a two-year research results obtained in 40 different land plots of the Sumy region (Ukraine) using domestic and imported machines, with wheat and buckwheat as crops. To ensure the study accuracy, the methodology was based on the CND 46.16.02.-96. Agricultural Machinery. Quality Indicators Nomenclature (Catalogue of Normative Documents, published in 1997). The research results demonstrate that the tilling depth depends on the manufacturing plant default settings, the speed regime, and the machine load. For the experimental data analysis, the Least Squares Means method was used. The research presents alternative methods of changing the tilling depth applicable for any machine aggregates with disk working bodies, and its results can serve the agricultural machinery designers.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46394520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
