Dehydrated Mink Manure as a Protein Source for Growing Pigs
Torkad minkgödsel som proteinkälla åt gödsvin
Acta Veterinaria Scandinavica volume 19, pages 73–83 (1978)
Abstract
The use of dehydrated mink manure as a protein source for growing pigs was studied by substituting 7.5 and 15 % (w/w) of the complete feed with manure and a corresponding amount of barley. The manure used had a poor feed value as compared to the values obtained earlier in digestibility tests in minks. The crude protein content was 21.3 %. The addition of mink manure to the feed did not adversely affect the feed consumption, nor were any effects on the health of the pigs observed. The differences in daily gain and feed efficiency recorded between the experimental groups were not statistically significant. The number of experimental animals was small, and a large variation occurred within the groups. The addition of mink manure to the diet resulted in lower weight gain, apparently due to a lower energy supply. The groups given mink manure received less feed units than the controls. No harmful effects of the manure feeding on carcase quality was observed and organoleptic tests revealed no changes in the smell or taste of the meat. No changes were found in the digestive tracts, livers or kidneys of the pigs.
Sammanfattning
Användningen av torkad minkgödsel som proteinkälla åt gödsvin undersöktes genom att ersätta 7,5 respektive 15 % (w/w) av helfoder-blandningen med minkgödsel och motsvarande mängd korn. I jämförelse med tidigare utförda smältbarhetsförsök med minkar, hade den använda gödseln lågt fodervärde. Råproteinhalten var 21,3 %. Någon negativ inverkan på svinens foderkonsumption eller hälsotillstånd kunde inte konstateras i samband med minkgödselutfodringen. Statistiskt signifikanta skillnader i vikt och foderutbyte kunde inte iakttagas. Försöksdjurens antal var litet, och stora variationer förekom inom försöksgrupperna. Minkgödseltillsatsen resulterade i långsammare tillväxt, uppenbarligen till följd av lägre energitillförsel. De försöksgrupper som fick av gödseln erhöll ett lägre antal foderenheter än kontrolldjuren. Vid organoleptisk undersökning av slaktkropparna kunde inga negativa förändringar med avseende å lukt eller smak på köttet konstateras. Svinens matsmältningskanal, lever och njurar uppvisade heller inga förändringar.
