There was no difference in the age and body weight of CMD gilts at puberty and first mating among the studied groups. However, the gilts in group A showed a lower mean age at puberty, and marginally lighter body weight than those in groups B and C. Birth weight showed a significant influence on the backfat thickness at puberty and first mating ( P <0.039 and 0.031).

Only the free form of glutamate has taste-enhancing properties as a unique umami taste, and when glutamate is bound to proteins, it is tasteless with no umami taste. Fermentation, ageing, ripening and heat cooking are typical natural processes of protein hydrolysis during which free glutamate is released. The food industry most commonly uses it in the form of monosodium glutamate (MSG) in amounts between 0.1 and 0.8% as a flavour enhancer. Since the beginning of the 21st century, its use as a flavour enhancer in meat and meat products with reduced salt content has become more widespread. The sodium content of MSG (12.28 g/100 g) is one-third that of salt (39.34 g/100 g), making MSG a promising salt alternative in sodium reduction strategies. There is no one-sided and conclusive scientific information reporting adverse human health effects of MSG in the general population, and it is still considered safe. However, in the wake of \"clean label\" initiatives, many consumers would prefer not to have additives or flavour enhancers such as glutamates in their food. This can be overcome by the known synergistic effect of natural 5'-ribonucleotides and glutamates found in seaweed, cheese, fish sauce, yeast extract, soy sauce, fermented soybeans and tomatoes, as they enhance the overall perception of umami flavour.","PeriodicalId":51685,"journal":{"name":"Journal of Central European Agriculture","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135699193","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}

These open areas play a very important role in the lives of children, in their development, their eating habits, and environmental awareness. For this reason, it is extremely important to select adequate plant species, which are not dangerous for the children. There are 10 public and 9 private preschool institutions in the entire area of the two Novi Zagreb (East and West) city districts. Only public kindergartens have been included in this research. The aim was to determine the size of green open space surrounding public kindergartens, analyse woody plants on site, determine the taxonomic affiliation of plant species, and detect the presence of poisonous and allergenic plant taxa. In green space surrounding kindergartens in the Novi Zagreb – East city district, 49 taxa of trees, and 18 taxa of shrubs and woody climbers from a total of 22 plant families have been identified.
