ELABORAÇÃO DE MORTADELA DE CMS DE CODORNAS POEDEIRAS DE DESCARTE ENRIQUECIDAS COM PÓ DE CASCA DE OVOS

O objetivo do trabalho foi desenvolver mortadela de carne mecanicamente separada (CMS) de codornas poedeiras (Coturnix japonica) de descartes enriquecida com diferentes níveis de pó de casca de ovo e avaliar os aspectos físicos, químicos, microbiológicos, sensoriais, juntamente com a aceitação e intenção de compra. Produziu-se quatro produtos, com diferentes níveis de inclusão de pó de casca de ovos sendo eles: tratamento 1 = mortadela controle, com 0%; tratamento 2 = mortadela com adição de 2%; tratamento 3 = mortadela com adição de 4% e tratamento 4 = mortadela com adição de 6% de pó de casca de ovo. Os produtos foram submetidos as análises microbiológicas, composição química, pH e sensorial. Os resultados foram satisfatórios, visto que todos os tratamentos estavam aptos ao consumo humano. A inclusão de pó de casca de ovo aumentou o teor de umidade, porém quando adicionado 2%, o produto apresentou melhor aceitação e menor valor calórico. Conclui-se que adicionando o pó de casca de ovo em mortadelas elaboradas com CMS de codornas de poedeiras de descarte ocorreu redução do valor calórico, apresentando melhor qualidade nutricional e aceitação para os atributos avaliados quando incluído 2% de pó de casca de ovo, levando o produto a possibilidade de comercialização, assim como, se tornando uma excelente alternativa de alimento

Variability of tillering in winter wheat (Triticum aestivum L.)

Variability of length of spike and number of spikelets spike-1 have share in forming of grain yield of wheat. The aim of this study was estimation of variability of length of spike and number of spikelets spike-1 in 20 genetically divergent wheat cultivars grown in different environmental conditions. The experiment was set up as a randomised block design in three replications. Obtained results indicated differences in average values of length of spike and number of spikelets spike-1 among tested cultivars in both years of experiment. In average for all cultivars length of spike was higher in the second year than in first year of experiment. Also, average value of number of spikelets spike-1 was higher in second year at the analysed wheat cultivars. The wheat cultivar Dejana expressed the highest length of spike (12.50cm) in average in the second experimental year while the wheat cultivar Sumadinka had the least length of spike (8.91cm) in average in the first year. Based on the results was established, variability of wheat cultivars for the both analysed traits of spike, as well as, significant differences between the wheat cultivars according to length of spike and number of spikelets spike-1 , which are in dependence of genetic and environmental factors

SSR analysis of molecular variance (AMOVA) for red clover genotypes

Red clover (Trifolium pratense L.) is forage legume with multipurpose value and evaluation of its genetic diversity is fundamental for its breeding. Plant material in this investigation consisted of 46 red clover accessions that came from throughout the world and our experiment was evaluated based on a trial that was set up in a randomized block design with three replications according to the UPOV descriptor (2001). The traits of interest were following agronomical and quality properties: number of internodes (NOI), stem length (STL), yield of green mass (YGM), yield of dry matter (YDM), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF). In the evaluation of red clover genotypes that were grouped according to the agronomical and chemical traits, the genotypes were separated into four clusters. The determined sample segregation was tried to interconnect with DNA level variation. Analysis of molecular variance (AMOVA) based on 14 Simple sequence repeats (SSR) was performed to assess genetic variation within and between red clover populations that were previously clustered. AMOVA did not show statistically significant intergroup differentiation. The index of genetic differentiation (ΦST) among groups was also estimated using the AMOVA procedure and it revealed weak genetic differentiation between these four clusters. As in many other marker supported experiments, in this investigation, AMOVA showed that the larger proportion of variation resided within population level

Healthy chickens, healthy children? Exploring contributions of village poultry-keeping to the diets and growth of young children in rural Tanzania

One in three Tanzanian children under five years of age is affected by stunting: an outcome of chronic undernutrition and an indication of impaired physical and cognitive development. The potential for livestock-keeping to contribute positively to children’s growth, including by providing nutrient-dense animal-source foods and household income to enable other nutritious food purchases, has been well-described but poorly demonstrated. Village chickens are an accessible and versatile form of livestock, kept in small free-ranging flocks by many households in resource-poor settings and often managed by women. This mixed methods research was undertaken in villages of Manyoni District in central Tanzania, alongside a project establishing a community-based vaccination service against Newcastle disease in village chickens. Significantly larger chicken flock sizes were identified as an outcome of vaccinating in a given campaign and of continuing to vaccinate at four-monthly intervals, compared to vaccinating less often or not at all. Chicken meat and eggs were infrequently eaten during the study period, with eggs more commonly hatched to increase chicken numbers and chickens retained for sale in times of need. Consumption of poultry products by mothers and their young children was closely linked and no gender-based differences in children’s consumption frequency were found. Analysis of national and regional food composition tables highlighted the need for recent and locally-derived data on the nutrient content of animal-source foods, to better reflect the products of indigenous livestock in low-input management systems. This thesis did not identify a significant impact of chicken-keeping on the height-for-age of children over a two-year period; however, importantly, it found no negative health or growth impacts which would undermine a continued focus on poultry interventions as a strategy to sustainably enhance nutrition at a household level

The Heirs of the Roman West

In this collection leading international authorities analyse the structures and economic functions of non-agrarian centres between ca. 500 and 1000 A.D. – their trade, their surrounding settlements, and the agricultural and cultural milieux. The thirty-one papers presented at an international conference held in Bad Homburg focus on recent archaeological discoveries in Central Europe (Vol.1), as well as onthose from southeastern Europe to Asia Minor (Vol. 2)
