Oikeat lajikkeet ja harkittu viljelytekniikka takaavat kauran terveysominaisuudet

Pohjoismaisen kauran laatu tunnustetaan maailman parhaaksi. Suomalaisen kauran valttina on vaaleus ja korkea laatu. Kauraa on käytetty pääasiassa rehuksi elintarvikekäytön ollessa vähäistä. Laadukasta suomalaista kauraa on viety elintarvikkeeksi ja rehuksi sekä USA:han että EU:n alueelle. Kauralla on merkitystä myös terveystuotteena, sillä Yhdysvaltain elintarvike- ja lääkevirasto (FDA) on hyväksynyt kauran terveysväittämän. Sen mukaan runsaasti kauralesettä ja/tai kaurahiutaleita sisältävä vähärasvainen ja -kolesterolinen ruokavalio voi alentaa sydäntautiriskiä. Kauran laatua on tutkittu vuonna 1998 alkaneessa kolmivuotisessa maa- ja metsätalousministeriön ja teollisuuden rahoittamassa projektissa "Kauraraaka-aineen laadunohjausjärjestelmä". Tavoitteena on selvittää kauran monipuolista ravitsemuksellista laatua ja siihen vaikuttavia tekijöitä. Lisäksi etsitään kauralajikkeita, viljelytekniikoita ja -oloja, jotka tuottavat teollisuuden käyttöön ravitsemuksellisesti ja teknologisesti parhaiten soveltuvaa laadukasta kauraa. Kauran viljelyoloja seuraamalla pyritään hallitsemaan riskitekijät, kuten mykotoksiinit ja kadmium, jotta kaura täyttää raaka-aineena elintarviketurvallisuuden ja viennin laatuvaatimukset. Tutkimuksen huipentumana on rakentaa kertyneen viljelypaikka- ja laatutiedon sekä säätietojen perusteella kauraraaka-aineen laadunohjausjärjestelmä.VokKV

Heredity of interocular similarities in components of refraction : a population-based twin study among 66-to 79-year-old female twins

Purpose To examine genetic influences on interocular similarities in ocular refraction and components of refraction among elderly female twins. Methods Refraction was assessed in 94 monozygotic (MZ) and 74 dizygotic (DZ) female twins aged 66-78 years. Absolute values of interocular differences (Aniso variables) in spherical refraction (SR), refractive astigmatism (AST), spherical equivalent (SE), corneal refractive power (CR), corneal astigmatism (CAST), anterior chamber depth (ACD) and axial length (AL) were calculated. The differences between sisters in each of the Aniso variables were calculated and graded into two categories, best differentiating the groups, here isometropic and anisometropic values. The cut-offs for grading as isometropic were AnisoSR <0.75 D, AnisoAST <0.5 D, AnisoSE <1.0 D, AnisoCR <0.5 D, AnisoCAST <0.50 D, AnisoACD AL MZ and DZ pairs in the Aniso variables and the interrelationships between the Aniso variables. Results When the Aniso variables were treated as continuous, no significant differences were found between the MZ and DZ subjects. When the proportions of isometropic intratwinpair interocular differences in the Aniso variables in the MZ and DZ cotwins were compared, the prevalences (MZ/DZ) were AnisoSR: 68%/60%; AnisoAST: 66%/57%; AnisoSE: 87%/68%; AnisoCR: 83%/78%; AnisoCAST: 69%/35%; AnisoACD: 77%/63%; and AnisoAL: 76%/60%. The differences were statistically significant for Aniso SE (p = 0.035, Fisher's exact test) and CAST (p = 0.007). The greater homogeneity in the interocular differences between the MZ sisters supports the assumption that isometropia of different elements of refraction is genetically influenced and tending to continue up to older ages. In cases where AnisoSE was = 1 D, no similar influence on emmetropization was observed. The difference between sisters in AnisoSE was associated with the intratwinpair difference in Aniso AL, but not with the intratwinpair differences in AnisoCR, irrespective of zygosity. Conclusion The higher prevalence of similarities in isometropia of the spherical equivalent and corneal astigmatism between the MZ pairs compared to DZ pairs is consistent with the view that genetic influences on the refractive elements of the eye, tending to isometropia, continue into older age. The interrelation between CR and AL tends to maintain isometropia of SE irrespective of zygosity.Peer reviewe

Compounded pelleted fibre feed and hay pellets as substitutes for hay in horse feeding

Use of compounded pelleted fibre feed and ground pelleted hay as substitutes for hay in horse feeding was investigated. Thirty horses were divided into a control group and two experimental groups. The control horses received 6 kg hay per day. The horses in the two experimental groups were fed 3 kg hay per day and the remainder of their hay portion was substituted with a compounded pelleted fibre-rich feed or pelleted hay. The influence of the diet on health, haemoglobin (Hb) and haematocrit (He) values, blood serum glucose concentration, as well as on faecal microflora and weight change was investigated. The health of the horses was found to be good, and the influence of the diets on the Hb and He values and faecal microflora as well as on weight change was not statistically significant. Horses receiving compounded feed had a higher (
