“…The daily weight-gain was much lower in the anaemic calves than in the normal ones. This finding is in accordance with the results of other experiments (MULLER and VOLKER, 1972; KIRCHGESSNER et al, 1974;BUNGER et al, 1980).…”

Summary The effect on the immune response of anaemic calves inoculated with inactivated ovine adenovirus type 1 vaccine was studied. Ten calves were fed on an iron‐poor diet. The same basic feeds were supplemented with iron salt for the' control calves. Haemoglobin concentration and PCV values were used to check the development of anaemia. After vaccination at the age of 60 days viral neutralizing antibodies appeared later and showed a lower titre in anaemic calves than in normal ones. At the age of 28 days there was no difference in the values of total serum protein, serum albumin or globulin between the groups. But at 60 days significantly lower serum globulin levels were found in the anaemic calves. The increase of IgG concentration after vaccination seen in normal calves was not observed in the anaemic animals. The average daily body weight gain was higher in the normal calves. Zusammenfassung Immunantwort bei anämischen Kälbern Studiert wurde die Immunantwort gegenüber inaktiviertem Adenovirus Typ 1 in anämischen Kälbern. Hierzu wurden 10 Kälber mit eisenarmer Diät gefüttert. Die Kontrollen erhielten dasselbe Futter, jedoch mit Eisenzusatz. Die Entwicklung der Anämie wurde durch Bestimmung der Hämoglobinkonzentration und der Zellvolumenwerte im Blut kontrolliert. Nach der Immunisierung in einem Alter von 60 Tagen traten die virusneutralisierenden Antikörper bei den Versuchstieren spater auf und zeigten geringere Titer als bei den Kontrollen. Im Alter von 28 Tagen waren keine Unterschiede zwischen den Gruppen in den Gesamtproteinwerten, in den Serumalbumin‐ und Serumglobulinwerten zu beobachten. Dagegen hatten die anämischen Tiere niedrigere Serumglobulinwerte im Alter von 60 Tagen. Im Unterschied zu den Kontrollen kam es bei den Versuchstieren zu keinem Anstieg der IgG‐Konzentration nach der Vakzination. Die durchschnittliche tägliche Körpergewichtszunahme war bei den Kontrollen höher. Résumé Réponse immunitaire chez des veaux anémiques On a étudié la réponse immunitaire contre un Adénovirus de type 1 inactivé chez des veaux anémiques. 10 veaux ont été alimentés à cet effet avec un régime pauvre en fer. Les contrôles ont reçu le même régime avec un supplément en fer. Le développement de l'anémie a été contrôlé par la détermination de la concentration d'hémoglobine et par les valeurs du volume cellulaire dans le sang. Après une immunisation à un âge de 60 jours, les anticorps neutralisant le virus sont apparus plus tard chez les animaux d'expirience qui présentèrent un titre plus faible que celui des animaux de contrôle. On n'a observé aucune différence entre les groupes à l'âge de 28 jours dans les valeurs des protéines totales, de l'albumine et des globulines sériques. Les animaux anémiques avaient des valeurs plus basses de globulines sériques à l'âge de 60 jours. A la différence avec les contrôles, il n'y a pas eu d'augmentation de la concentration des IgG chez les animaux d'expérience après la vaccination. L'augmentation moyenne journalière de poids fut plus élevée chez les animaux de contrôle. Resumen L...

In a study on the nutrient and energy content of defined parts of the body, five veal calves each were slaughtered at the start and at the end of two fattening periods with liquid diet. The whole body weight of the three groups of veal calves averaged 56, 96, and 151 kg. All body organs and parts resulting from slaughtering and partitioning were weighed, divided among 11 groups of cuts, and analyzed for dry matter, crude protein, ether extract, ash and energy. The various cuts showed different weight gains in relation to live weight. Blood, hide and gastrointestinal tract and also total meat increased about proportionally to live weight, the innards and bones developed more slowly. During the 12-week fattening period the percentage of total meat of the carcass increased from 68 to 72, the percentage of adipose tissue from 3 to 8. Over the same period the percentage of bones decreased from 26 to 19. The groups of organs and tissues showed considerable differences in nutrient content. With an increase in ether extract concentration from 39 to 69% of fresh matter during fattening, the adipose tissue of finished calves contained 13 times the amount of ether extract of animals at the start of fattening. The deposition of fat in the skeleton, in contrast to the soft tissues, already reached the maximum level in the weight range under 100 kg. Among the four defined groups of lean meat there were no major differences in crude protein and ash. In the total meat crude protein content declined from 20.4 to 19.3%, ash content from 1.7 to 1.3% of fresh matter during fattening. The total protein content amounting to 13.2 kg in the group after finishing reached 2.7 times the level of the inital content. At the same time the fat content of the total meat increased from 2.4% initially to 7.7% at the end. The highest level found was 11.3% in the lean meat of the chest/abdominal part. In the total meat about 2.8 times as much fat was retained in the second period of fattening than in the first period.

Wachstum und hämatologische Kriterien von Ratten bei unterschiedlicher Protein- und Eisenversorgung

In a two-factorial experiment with growing rats, protein content of diet (5, 25, 45%) and Fe supply (5, 25, 625 mg/kg diet) were changed. Both factors as well as their interactions influenced growth (p less than 0.001). The growth was reduced especially by deficient protein supply but although by inadequate iron supply and in a smaller degree by an excessive protein content of the diet. Hematological values as hemoglobin content, counts and volume of erythrocytes, hematocrit, MCH and MCHC - measured after 35 days of the experiment - were influenced by both factors and their interactions, too (p less than 0.001). Again deficient protein supply and insufficient Fe supply have the marked effects. Referring life weight as well as hematological parameters, the deficient protein supply was - independent of Fe supplementation - the limited factor, whereas in the cause of higher protein content (25, 45%) an insufficient Fe supply has negative effects.
