Última Performance and diarrhoea in piglets following weaning at seven weeks of age: Challenge with E. coli O 149 and effect of dietary factors Organic Eprints Sørensen, Martin T.; Vestergaard, Ellen-Margrethe; Jensen, Søren K.; Lauridsen, Charlotte; Højsgaard, Søren. Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding) were tested in four separate experiments for the effect on diarrhoea. To introduce a diarrhoea-like condition, half of the piglets were challenged with an inoculation of an E. coli O 149 dose of 1 x 108 colony forming units on day two and three after weaning (day of weaning = day one). All piglets were susceptible since the dams were tested mono-zygotic susceptible to the attachment site of E. coli O 149 in the intestines. Each of the four experiments included 32 piglets from 4 sows. The design was 2 x 2... Tipo: Journal paper Palavras-chave: Health and welfare; Feeding and growth.

Surfôr fra kortvarig eng (KS) hadde lavere innhold av C18:3c9,12,15 enn surfôr fra langvarig eng(LS)og raigrassurfôr. Likevel ga surfôr fra KS høyest innhold av C18:3c9,12,15 i melk. Årsaken var redusert hydrogenering i vomma. Dette gjaldt også summen av alle umettede C18-fettsyrer men ikke C18:1c9 eller C18:2c9,12. Årsaken til redusert hydrogenering for KS kan være rødkløverens innhold av PPO.

Ano: 2011 URL: http://orgprints.org/18817/4/18817.pdf Indflydelse af høstmetode og konservering på vitamin- og fedtsyreindhold Organic Eprints Jensen, Søren K.; Søegaard, Karen; Sehested, Jakob; Lindqvist, Hanna; Nadeau, Elisabet. I FØJO III projektet ECOVIT undersøges det, i hvilket omfang det er muligt at optimere vitaminindholdet i grovfoderafgrøderne ved at foretage det optimale valg af afgrøder, høsttidspunkt, forvejring og lagerform. I projektet har vi undersøgt forskellige græsmarksafgrøder dyrket i både Danmark og Sverige og sammenholdt resultaterne fra de to lande. Resultaterne viser, at der er betydelige forskelle i vitaminindholdet mellem afgrøder og hen over dyrkningssæsonen. Generelt har bladrige grønne afgrøder det højeste vitaminindhold. Tabet under forvejring og lagring varierer også ganske betydeligt, og det er vanskeligt at give præcise retningslinjer for, hvordan dette tab minimeres mest muligt. Det ser dog ud til, at en lang forvejringsperiode øger tabet, og det... Tipo: Report chapter Palavras-chave: Farming Systems; Animal husbandry; Feeding and growth; Farm nutrient management.

This study was designed to investigate the effect of vitamin E supplementation on vitamin E depots and immune responses in weaned pigs after an E. coli inoculation. The design was a 2×2 factorial with vitamin E supplementation (150 mg/kg RRR-α-tocopheryl acetate versus a control diet containing 60 mg all-rac-α-tocopheryl acetate) and E. coli 0 149 inoculation (inoculation of 1×108 CFU on day 2 and 3 after weaning versus inoculation of vehicle). The pigs were housed individually during the experiment which lasted for 10 days from weaning at 7 weeks of age. Blood was sampled on day 1 (day of weaning) and 9 of the experiment, and serum was analyzed for α-tocopherol concentration. On day 10 of the experiment, pigs were killed and samples of liver, heart,... Tipo: Journal paper Palavras-chave: "Organics" in general; Farm nutrient management.

On five organic dairy farms there was a positive effect of a high vitamin content in the home-grown roughage on the vitamin content of the milk produced. Vitamins and minerals are of crucial importance for the health and performance of the animals, and they also affect the nutritional value of the products. The highest concentrations of pro-vitamin A (in the form of beta-carotene) and vitamin E (alfa-tocopherol) are found in grass, legumes and other green plants, while seeds and whole-crop silage only contain small amounts of vitamins. While the requirements for for fat-soluble vitamins of grazing cattle are normally met via their intake from pasture, the supply of fat-soluble vitamins may decrease to very low amounts when conserved herbage is used...

Ano: 2010 URL: http://orgprints.org/17870/1/17870.pdf Vitaminer og fedtsyrer i hø og ensilage – hvad sker der vid forvejring og lagring? Organic Eprints Jensen, Søren K.; Hymøller, L.; Soegaard, Karen; Lindqvist, H.; Nadeau, E.. For at undersøge stabiliteten af vitaminer i moderne ensilage- og høproduktion, har FØJO III projektet ECOVIT, igennem to vækstår, målt vitaminindholdet i forskellige græsmarksafgrøder ved forskellige høsttidspunkter og sletintervaller. Resultaterne viser, at det største tab af vitaminer og umættede fedtsyrer sker i forbindelse med forvejringen, mens tabet i lagringsperioden er begrænset.

Ano: 2010 URL: http://orgprints.org/19767/1/ICROF_Nyt2010_2.pdf Undgå indkøbte mineraler Organic Eprints Sehested, Jakob; Jensen, Søren K.; Søegaard, Karen. En grøn foderration med brug af urter i græsblandingerne gør det muligt i højere grad at blive selvforsynende med vitaminer og mineraler. Et forsøg med to økologiske fodringsstrategier har vist, at køer der ikke får tilskud af mineraler, men derimod får en foderblanding med et højt indhold af naturlige mineraler og vitaminer, har samme foderoptagelse, mælkeproduktion og reproduktion, som køer på en mere traditionel foderration. Blodprøver viste desuden, at køer, der udelukkende fik mineraler og vitaminer naturligt indeholdt i de forskellige fodermidler, havde samme A- og E-vitaminniveau i blodet, som køer der fik tilsat mineralblanding til foderet.

Ano: 2010 URL: http://orgprints.org/20732/3/20732.pdf Contents of α-tocopherol and β-carotene in grasses and legumes harvested at different maturities Organic Eprints Danielsson, Hanna; Nadeau, Elisabet; Gustavsson, Anne-Maj; Jensen, Søren K.; Soegaard, Karen; Nilsdotter-Linde, Nilla. Concentrations of α-tocopherol and β-carotene in forage species at various maturities were studied in Scandinavia. Red clover (RC)/timothy (TI), RC/meadow fescue (MF), and birdsfoot trefoil (BT)/TI mixtures were grown in Skara and Umeå, Sweden. RC/TI,RC/perennial ryegrass (PR), white clover/PR and BT/TI were grown in Foulum, Denmark. Forages in Sweden were cut one week before heading (BH), at heading and one week after heading of TI. The regrowth was cut six and eight weeks after each harvest in the spring growth cycle. In Denmark, one first harvest and three regrowths were taken. Results from Skara and Foulum are presented. Highest concentrations of α-tocopherol and β-carotene (mg kg-1 DM) in legumes were found in BT grown in Skara (49.8 and 69.6 in...

Ano: 2008 URL: http://orgprints.org/19768/1/EGF2008vitaminslutlig.pdf Immunological effects of feeding macroalgae and various vitamin E supplements in Norwegian white sheep-ewes and their offspring Organic Eprints Novoa-Garrido, Margarita; Aanesen, Lise; Lind, Vibeke; Larsen, Hans Jørgen S.; Jensen, Søren K.; Govasmark, Espen; Steinshamn, Håvard. It is assumed that ewes raised in areas with long indoor winter feeding periods need to be supplemented with vitamins or other substances that help to maintain the health status of the animals. Various supplements are available on the market, but the most widely used supplemental antioxidant and vitamin E source is synthetic all-rac-α-tocopheryl acteate. The objective of the present study was to compare potential vitamin E and immune stimulant sources with synthetic vitamin E regarding bioactivity associated with immunological parameters in order to identify alternatives to synthetic vitamin E for small ruminants. Sources tested were meal of the seaweed Ascophylum nodosum and natural RRR-α- tocopheryl acetate. Forty pregnant ewes were randomly allocated to...

Surfôr fra kortvarig eng har gitt høyere andel av flerumettede fettsyrer i melk sammenlignet med surfôr fra langvarig eng men dette har ikke ført til at melka ble mer utsatt for lysindusert oksidasjon. Tilskudd av α-tokoferol økte innholdet av α-tokoferol i melka men hadde ingen effekt på melkas oksidative stabilitet. Surfôr fra kortvarig eng ga høyere innhold av isoflavoner og lavere innhold av lignaner i melk enn surfôr fra langvarig eng.

Red clover and high proportion of forage in dairy cow diet increases the concentration of bioactive substances in milk, e.g. unsaturated fatty acids and antioxidants. In the present experiment twenty-four Swedish Red dairy cows were fed three silages in a Latin Square design to study the effect of silage botanical composition and harvest time on milk fatty acid, α-tocopherol and β-carotene concentration. The silages were red clover/grass silage (mixture of first and second cut), red clover/grass silage (mixture of first, second and third cut) and birdsfoot trefoil/grass silage (mixture of first and second cut). Botanical composition and harvest system affected silage vitamin and fatty acid concentration with higher concentrations of α-linolenic acid,...

Forsyningen af de økologiske husdyr med mineraler og vitaminer er et af de områder, hvor der endnu ikke er fundet løsninger, som udnytter muligheden for recirkulering og selvforsyning på bedriften. Formålet med dette forsøg var at undersøge, om en integreret vitamin- og mineralforsyning kunne opnås i økologisk mælkeproduktion ved i så høj grad som muligt at anvende hjemmedyrkede grovfodermidler med et højt naturligt indhold af vitaminer og mineraler. Perspektivet er at opnå en højere grad af selvforsyning med mineraler og vitaminer til malkekøerne på den enkelte bedrift. I forsøget var det muligt at opnå et tilstrækkeligt indhold af vitaminer og mineraler i foderrationen til malkekøerne i forhold til fodringsnormen i såvel Danmark som USA uden tilskud...

Ano: 2010 URL: http://orgprints.org/17915/1/17915.pdf Quality and vitamins in forage herb and legume species Organic Eprints Elgersma, Anjo; Søegaard, Karen; Jensen, Søren K.. Grasslands provide an important part of the feed used by domestic and wild ruminants. Fresh herbage is an important natural source of vitamins in ruminant diets. Concentrations of vitamins in plants depend on factors such as regrowth stage, temperature and day length, N fertilisation and leaf proportion in the harvested herbage. Most studies on vitamin concentrations in forages have been carried out with agronomical important grass species such as perennial ryegrass and legume species such as white clover, but hardly with other grassland forage species. As data of dicotyledonous species grown in a sward are scarce, yield, quality and vitamin contents in a number of herb (hereafter referred to as forb) and legume species were compared to a grass-clover...

Ano: 2013 URL: http://orgprints.org/24743/6/24743.pdf Effekten av fôrtilskudd fra sjø og land på bakteriebalansen i tarmen hos søyer og deres avkom Organic Eprints Novoa-Garrido, Margarita; Aanensen, Lise; Larsen, Hans Jørgen S.; Jensen, Søren K.; Steinshamn, Håvard. E vitamin er nødvendig for drøvtyggere for å opprettholde et velfungerende immunsystem, høyt reproduksjonsnivå, og god melk- og kjøttkvalitet. Innholdet av antioksidanter i råmelken påvirker absorpsjonen av antistoffer hos nyfødte kalver. Selen-innholdet i jord kan være lavt, og dermed kan hjemmedyrket grovfôr være fattig på selen. Hvis grovfôret også er fattig på E-vitamin, som samhandler med selen i sine biologiske effekter, kan underforsyning lett oppstå. Derfor blir rasjonene til drøvtyggere supplert med syntetisk produsert E-vitamin for å sikre tilstrekkelig inntak. Det er imidlertid kjent at syntetisk E-vitamin består av 87,5 % molekyler med ikke-naturlig konfigurasjon og som biologiske ikke er like effektiv (Jensen & Lauridsen, 2007). Av denne...

The objective was to compare the effects of supplementing lactating dairy cows with synthetic (All-rac), natural (RRR) α-tocopheryl acetate or seaweed with a control on the concentration of α-tocopherol in blood and milk. Twenty four dairy cows in mid lactation, fed an organic feed ration, were randomly allocated to the four treatments in a replicated Latin square design. Plasma and milk α-tocopherol concentrations were higher in RRR and All-rac than in the other treatments and higher in RRR than in All-rac. RRR-α-tocopherol was the predominant steroisomer (> 86%), in both plasma and milk, whereas the remaining part was largely made up by the three synthetic 2R isomers. In cows fed the control, seaweed and RRR, the proportion of RRR-α-tocopherol in... Tipo: Conference paper, poster, etc. Palavras-chave: Dairy cattle; Feeding and growth; Health and welfare.

Organic Eprints Steinshamn, Håvard; Luteberget, Ingvild Steinnes; Larsen, Hans Jørgen S.; Jensen, Søren K.; Thuen, Erling. Sjølv om α-tokoferolinnhaldet (39 mg/kg DM) i surfôr ikkje var spesielt høgt, var det tydelegvis nok når surfôropptaket var så høgt som i dette forsøket.

Urter i græsmarken er blevet undersøgt i forsøg på fem økologiske kvægbrug og ved Foulum. Vækst, konkurrenceevne, foderværdi og mineralindhold i de enkelte arter i tre forskellige blandinger er undersøgt for betydningen af gylletilførsel, slæt/afgræsning og markens alder, og variation mellem gårde er beskrevet. De enkelte urter viste generelt det samme mønster på de forskellige steder, hvilket gør det muligt med generelle konklusioner. En oversigt over konklusioner for de enkelte urter er vist på sidste side af bilaget. Cikorie og vejbred var de stærkeste og indeholdt derudover en stor andel mineraler. Kommen var også forholdsvis stærk, især under slætforhold. Bibernelle og kællingetand var forholdsvis svage konkurrenter, men mange steder var der dog en...

Ano: 2010 URL: http://orgprints.org/17910/1/17910.pdf Effects of supplementing mid-lactation dairy cows with seaweed and vitamin E on plasma and milk α-tocopherol and antibody response to immunization Organic Eprints Kidane, Alemayehu; Nesheim, Ingvild Luteberget; Larsen, Hans Jørgen S.; Thuen, Erling; Jensen, Søren K.; Steinshamn, Håvard. The objective of the current experiment was to compare the effects of supplementing mid-lactation dairy cows with all-rac-α-tocopheryl acetate (SyntvE), RRR-α-tocopheryl acetate (NatvE) or seaweed meal (Seaweed) in the presence of a Control group (no supplemental vitamin E or seaweed) on the concentration of α-tocopherol in plasma and milk, and antibody response following immunization. The hypothesis was that supplementation of dairy cows with vitamin E, regardless of its form, would increase plasma and milk α-tocopherol compared to the control diet and this incremental response would be bigger with NatvE than SyntvE. Furthermore, it was hypothesized that vitamin E, regardless of its form, will provide an improved adaptive immune response to... Tipo: Journal paper Palavras-chave: Dairy cattle; Health and welfare.
