Immunological effects of feeding macroalgae and various vitamin E supplements in Norwegian white sheep-ewes and their offspring 21
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...

Økologisk sauehold 21
Grøva, Lise; Henriksen, Britt I.F.; Lind, Vibeke; Nyhammer, Kjartan.
Småskriftet - omhandler ulike sider ved sauhold som er spesielt for økologisk drift. Utfordringene for økologisk sauehold er knyttet bl.atil fôring, driftsopplegg, helse og dyrevelferd. Ved omlegging til økologisk drift må en vurdere forholdene på den enkelte gård: Arealtilgang, behov for kraftfôr, krav til liggeareal.

Locally produced legumes and seaweed. Sustainable protein sources for a self-sufficient European animal production? 21
Novoa-Garrido, Margarita; Bay-Larsen, Ingrid; Heckendorn, Felix; Weisbjerg, Martin R.; Molina-Alcaide, Eduarda; Lind, Vibeke.
The animal feeding industry is looking for new local sources of high quality protein in order to reduce import and ensure sustainable and environmental friendly animal production systems. Local legumes and seaweeds may be alternative sources of protein. We present in this paper the background for the ongoing Norwegian Research Council project Legumes and seaweeds as alternative protein sources for sheep (AltPro), which aims to investigate the suitability and potential of legumes and seaweeds as new and underutilized protein sources in sheep diets. The project addresses several critical aspects for the future development of the agriculture industry in Norway applicable to other European countries from an integrated social and natural scientific approach:...

Immunological effects of feeding different sources of vitamin E and seaweed in a sheep herd during the winter season 21
Novoa-Garrido, Margarita; Aanesen, Lise; Lind, Vibeke; Larsen, Hans J.S.; Govasmark, Espen; Steinshamn, Håvard.
In winter fed organic raised sheep inadequate plasma vitamin E levels is common and therefore supplementation is recommended. The objective of the present work was to test the supplementation of natural vitamin E and seaweed meal on the immune status of ewes and their offspring. Forty Norwegian White Sheep ewes were randomly allocated to three supplementation treatments: natural vitamin E, synthetic vitamin E, seaweed meal, and control. The feeding experiment lasted the entire indoor feeding period. Ewes and newborn lambs were vaccinated against different environmental microorganisms and pathogens. Different immunological parameters were measured. Supplementing the ewes with natural vitamin E had positive effect on immunity against Mycobacterium...
