Effects of αs1-casein and k- casein genotypes on nutrient intake and milk production in Girgentana goats: a further investigation

2013

The influence of polymorphism at αs1-casein locus (CSN1S1) on goat milk properties is adequately known, whereas the knowl- edge is limited on the effects of κ-casein gene variants (CSN3), C-093 and the association between variants of CSN1S1 and CSN3 Milking technique in jenny: effects on milk production genes. This study aimed to investigate the effect of some CSN1S1-CSN3 composite genotypes (CG) on feed intake and milk production of 95 Girgentana goats from 6 experiments (551 Rossella Di Palo, Diana Neri, Barbara Ariota, Rosanna Serafini, observations). Goats, genotyped using specific PCR protocols at DNA level and IEF technique at milk protein level, were equal at αs2-casein and β-casein …

Feed intake, milk composition and cheesemaking properties in Girgentana grazing goats with different genotype at αs1-casein and K-casein

2009

Milk ability for cheese manufacturing depends on both animals utilization of dietary nutrients and genetic polymorphism of caseins. It is well known that strong alleles associated with high content of as1-casein increase cheese-making properties of goat milk, whereas there is little information about effect of genetic variants of κ-casein. The aim of this experiment was to investigate the effect of some composite as1-casein and κ-casein genotypes n changing feeding behavior at pasture and milk yield and properties of Girgentana goats. Forty goats were genotyped at as1, as2, b and κ-casein loci using specific PCR protocols at DNA level and IEF technique at milk protein level. Twelve goats, d…

PPHD: une plateforme pour le phenotypage a haut debit

2012

International audience; The methodologies for genotyping and high throughput automated platforms for the production of type-omics (genomics, transcriptomics, protected omics ...) have greatly increased over the last few years and are now available to analyze the expression of genes of plants in several environmental conditions. However, a break of conceptual and technical services, non-destructive characterization and dynamic phenotypes, at the organ or plarite, has hundreds of related genotypes (Broadband) remains the limiting factor for the discovery of new characters or new varieties. This systematic exploration of diversity. Genetics within a species or between species requires platform…

Studies concerning the production of volatile oil, rhizomes and roots, to different genotypes of Valeriana officinalis L.

2010

Valeriana officinalis L. is considered to pertain to European species, with great ecologic plasticity, which allows its adaptation to climate conditions characteristics to plain areas and also to mountain areas up to an altitude of 2400 meters. The species is a well-known curative plant, with a long history and multiple uses. Essential oils deriving from this species revealed the interest of researchers in food industry, cosmetics and officinal industry, furthermore being used as additives too.The raw material from which essential oils are being extracted is represented mainly by rhizomes and roots. This study has the purpose to emphasize the differences of essential oils production registe…

Metabolomics approach to studying minimally processed peach (Prunus persica) fruit

2012

Fresh-cut fruit products for both retail and food service applications have increasingly appeared in the market place in recent years. Among different fruit types, peaches can be used and are highly appreciated as fresh-cut product although their commercial success is limited due to their short shelf-life and the quick onset of wounding-related physiological reactions. In this work we analyzed the technological and physiological changes induced by fresh-cut preparation in three different types of peach cultivars: 'Fayette' (melting), 'Wilhelmina' (non-melting) and 'Ghiaccio3' (stony hard). We performed a metabolite targeting profiling to focus on the changes in organic acid levels, importan…

Nitrogen uptake and nitrogen fertilizer recovery in old and modern wheat genotypes grown in the presence or absence of interspecific competition

2015

Choosing genotypes with a high capacity for taking up nitrogen (N) from the soil and the ability to efficiently compete with weeds for this nutrient is essential to increasing the sustainability of cropping systems that are less dependent on auxiliary inputs. This research aimed to verify whether differences exist in N uptake and N fertilizer recovery capacity among wheat genotypes and, if so, whether these differences are related to a different competitive ability against weeds of wheat genotypes. To this end, 12 genotypes, varying widely in morphological traits and year of release, were grown in the presence or absence of interspecific competition (using Avena sativa L. as a surrogate wee…
