Hematological and Blood Chemical Data in Pigs Fed on Fine, Medium and Coarse Ground Dry Grain

Hematologiska och blodkemiska undersökningar au svin, som torrutfodrats med finmalet, medelgrout och grout spannmål

Abstract

Blood was collected the day before slaughter from pigs fed fine, medium or coarse ground grain and examined in accordance with Tables 1–3. Of the 15 pigs (group 1) on the finest meal all except one developed parakeratotic or erosive changes (Figs. 1–5) in the pars oesophagea of the stomach. In group 2 (medium ground) the corresponding number was seven out of 18. No pathological alterations could be detected in the stomach of the pigs on coarse grain.

Statistically significant or almost significant differences were obtained between the groups for hemoglobin, hematocrit, number of erythrocytes, urea-N and pepsinogen. A much wider range was observed in the γ-globulins of the group on fine grain than in the other two groups. The differences in proteins were, however, not significant. To see whether the observed differences between the groups were related to the gastric pathological alterations or to the feed, a comparison was made between pigs with and without pathological changes (Table 3). There were still significant, though smaller, differences in the hemoglobin and hematocrit values. A higher level of significance was only obtained for pepsinogen.

Sammanfattning

Dagen före start togs blodprov från grisar som utfodrats med finmalet, något grövre eller grovmalet spannmäl (korn). Vid slakten konstaterades att av femton grisar, som erhållit finmalet foder (grupp 1), uppvisade fjorton stycken parakeratos eller erosioner i magsäckens pars oesophagea. Hos djur som utfodrats med något grövre foder var motsvarande siffror sju av aderton. De djur som fått grovt foder var utan anmärkning. Blodet undersöktes i enlighet med tabell 1–3. Signifikanta eller näzstan signifikanta skillnader mellan grupperna erhölls för hämoglobin, hämatokrit, antal erytrocyter, urea-kväve och pepsinogen. γ-globulinet visade större variation bland djuren som utfodrades med finmalet foder än hos övriga djur. Men skillnaderna i proteiner var ej signifikanta.

För att se om iakttagna skillnader mellan grupperna var relaterade till magsäcksförändringarna eller till foderstrukturen jämfördes djur med och djur utan magsäcksförändringar. Skillnaderna var fortfarande signifikanta (ehuru mindre) vad gäller hämoglobin och hämatokritvärdena. En högre gr ad av signifikans erhölls for pepsinogen.
