This study aims to evaluate the effects of the birth weight of crossbred Moo Lath x Duroc (CMD) gilts on their puberty and first mating age, including the body condition and morphology. The litter size and birth weight of their offspring were also evaluated. Eighteen (18) CMD gilts were selected after weaning and kept in an individual pen 1.5 x 2 x 1 m after puberty. The gilts were grouped into three groups based on birth weight: groups A, B, and C (with <0.7, ≥0.7−0.9≤, and >0.9 kg, respectively). 15 mature purebred Moo Lath (PML) gilts reared by farmers were also involved in this study to compare the morphology between the CMD and PML at first mating. 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). The CMD gilts could have their first mating at 193 days, that is at their 3 rd and 4 th estrous cycle, with approximately 40 kg of body weight, 38 mm of backfat thickness, 90 cm of heart girth, 100 cm of body length, and 51 cm height at wither. The CMD gilts’ birth weight did not influence their litter size, but influenced their offspring’s birth weight.

Glutamate is one of the most abundant amino acids in nature, accounting for up to 8-10% of most dietary proteins and peptides and most tissues. 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.

Jerusalem artichoke is crop with the possibility of a wide using. The main nutrient of this plant is a non-starch polysaccharide inulin, which is considered like prebiotic. Young rabbits after weaning lose an immunity obtained from colostrum; are stressed by weaning; pre-moult; the permanent incisors are growing and a starch digestion by an enzyme amylase is not fully developed. The aim of this study was to evaluate the effect of the dietary supplement of dried Jerusalem artichoke tuber and tops (the sources of non-starch saccharide) on growth performance and health status of broiler rabbits after weaning in view of prices and efficiency of feeding mixtures. The test was realized through experiments with a different percentage of Jerusalem artichoke tuber (25%, 10%) and top (30%, 20%, 10%). Every experiment was composed of 2 groups – the control group without a supplement of Jerusalem artichoke and an experimental group with a different percentage of Jerusalem artichoke tuber and top. Experimental animals (1095 HY PLUS broiler rabbits) were weaned at 33 - 35 days of age and were fed by complete granulated feeding mixture ad libitum for the whole feeding period. Statistical analyses were performed by using SAS 9.3 The statistical differences ( P <0.05) were found in average daily gain (rabbits fed 25% Jerusalem artichoke tubers 42.37±13,96 g/day vs. control 36.42±12.91 g/day) and mortality (rabbits fed 10% Jerusalem artichoke tubers 4.17% vs. control 10.83%; rabbits fed.20% Jerusalem artichoke tops 5.26% vs. control 16.67%).

Plantings surrounding kindergartens are an integral part of urban green spaces. 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. Similary, in the Novi Zagreb – West city district, 49 taxa of trees, and 24 taxa of shrubs and woody climbers from a total of 26 plant families have been determined in kindergarten plantings. A total of 32 poisonous taxa, and 36 allergenic taxa have been catalogued in the Novi Zagreb – East city district, while a total of 34 poisonous taxa, and 42 allergenic taxa have been listed in the Novi Zagreb – West city district. The most poisonous species were: Taxus baccata , Prunus laurocerasus and Sambucus nigra . The species with the highest allergenic potential were: Thuja occidentalis , Betula pendula and Acer platanoides

The aim of study was to determine ligno-cellulose quality and calorific value of cup plant Silphium perfoliatum L., whereas impact of nutrition, years and sites on the quality were evaluated as main effects within a huge pilot field experiment. Two complete data sets of acid-detergent fiber (ADF), acid-detergent lignin (ADL), crude cellulose (CE), hemicellulose (HEM), neutral-detergent fiber (NDF) and high heating value (HHV) were evaluated, a primary one in terms of quality content and a secondary one in terms of quality yield. Average, minimal and maximal ADF content was 43.73 – 31.32 – 48.94%, ADL 10.22 – 7.21 – 12.54%, CE 33.51 – 24.11 – 37.30%, HEM 4.17 – 2.33 – 5.75%, NDF 48.12 – 34.94 – 54.69% and HHV 15.83 – 15.21 – 16.79 MJ/kg, respectively. Adequate values of ADF yield was 5.461 – 1.021 – 20.827 t/ha, ADL 1.274 – 0.235 – 5.115 t/ha, CE 4.187 – 0.786 – 15.112 t/ha, HEM 0.569 – 0.055 – 2.447 t/ha, NDF 6.041 – 1.139 – 23.273 t/ha and HHV 195.528 – 36.481 – 704.914 GJ/ha, respectively. Ligno-cellulose quality and calorific value of cup plant vary with environment and management practices. In terms of quality content, the influence of the sites was generally the most significant (valid for ADF, ADL, CE and NDF), or alternately with the influence of the years (HEM and HHV) it was higher than a medium influence of the nutrition. In terms of quality yield the years has been confirmed the most important factor (mainly because great increasing of phytomass yield by utility year of that perennial crop), followed by nutrition and then by sites with the least impact, whereas that impact order was valid for each of parameter.
{"title":"Ligno-cellulose quality and calorific value of green phytomass of Silphium perfoliatum L. cultivated on marginal soils under conditions of moderate continental climate of Central Europe","authors":"Š.

Two complete data sets of acid-detergent fiber (ADF), acid-detergent lignin (ADL), crude cellulose (CE), hemicellulose (HEM), neutral-detergent fiber (NDF) and high heating value (HHV) were evaluated, a primary one in terms of quality content and a secondary one in terms of quality yield. Average, minimal and maximal ADF content was 43.73 – 31.32 – 48.94%, ADL 10.22 – 7.21 – 12.54%, CE 33.51 – 24.11 – 37.30%, HEM 4.17 – 2.33 – 5.75%, NDF 48.12 – 34.94 – 54.69% and HHV 15.83 – 15.21 – 16.79 MJ/kg, respectively. Adequate values of ADF yield was 5.461 – 1.021 – 20.827 t/ha, ADL 1.274 – 0.235 – 5.115 t/ha, CE 4.187 – 0.786 – 15.112 t/ha, HEM 0.569 – 0.055 – 2.447 t/ha, NDF 6.041 – 1.139 – 23.273 t/ha and HHV 195.528 – 36.481 – 704.914 GJ/ha, respectively. Ligno-cellulose quality and calorific value of cup plant vary with environment and management practices. In terms of quality content, the influence of the sites was generally the most significant (valid for ADF, ADL, CE and NDF), or alternately with the influence of the years (HEM and HHV) it was higher than a medium influence of the nutrition.
