“…As was observed in the cow [Lee et al, 1980], ewe Outteridge and Lee, 1981] and guinea pig [Nordin and Lee, 1982], the neutrophils were the predominant cell type in colostrum and involution secretion. Since there was no detectable infection, such a great influx of neutrophils may be a response to the disten sion of the gland and the accumulation of cellular debris.…”

Cells in pig colostrum, milk and involution secretion were identified using light and electron microscopy. Cell types identified were neutrophils, macrophages, epithelial cells, eosinophils and lymphocytes. The neutrophils predominated in colostrum and involution secretion, whereas in milk it was the epithelial cell. Macrophages and lymphocytes were present throughout lactation and so too were eosinophils which were always present in lower concentrations. Both neutrophils and macrophages were seen with phagocytic vacuoles containing either lipid, casein or cellular debris. The possible roles played by the phagocytic and lymphoid cells in the protection of the mammary gland of the sow and the gut of the neonate from pathogenic microorganisms is discussed.

“…However, another report showed that in human milk neutrophils may be prominent (13). It has also been found that in the colostrum of cows (6), ewes (7) and guinea pigs (10) neutrophils outnumbered other cells. O u r findings show that in sows neutrophils prevailed at every lactation stage ( Table 2 and 3), which agrees with the results obtained by EVANS et al (11), who published the first report about cell types in pig milk, did not distinguish macrophages, considering them probably as lymphocytes and so his results cannot be compared with subsequent papers in which macrophages were identified.…”

Summary The morphology and differential counts of the cells in sow's colostrum and milk were ascertained. Mean values of the total cell count for colostrum and milk were 1.06 + 0.79 and 1.57 + 0.94 × 109 cells/l, respectively. There was no linear correlation between the time of lactation and the total cell number. Six cell types were identified in the secretions: neutrophils, eosinophils, lymphocytes, macrophages, epithelial cells and anucleate cells. Besides the predominance of neutrophils, the prevalence of numerous epithelial cells and anucleate cells appeared to be an important feature of sow's mammary secretion. Zusammenfassung Zellen im Milchdrüsensekret des Schweines I. Morphologie und Differentialzählung während der Laktation Die Untersuchungen betreffen die Morphologie und die Differentialzählung der Zellen im Kolostrum und in der Milch von Sauen. Die durchschnittlichen Gesamtzahlen betrugen im Kolostrum 1,06 + 0,79 × 109 und in der Milch 1,57 + 0,94 × 109 Zellen pro Liter. Zwischen dem Laktationsstadium und der Gesamtzellzahl bestand keine lineare Korrelation. In den Sekreten konnten 6 Zellarten identifiziert werden: Neutrophile, Eosinophile, Lymphozyten, Makrophagen, Epithelzellen und kernlose Zellen. Abgesehen von der Dominanz der Neutrophilen scheint das Vorkommen von zahlreichen Epithelzellen und kernlosen Zellen ein wesentliches Charakteristikum der Milchdrüsensekrete der Sau zu sein. Résumé Cellules dans la sécrétion lactée de la truie I. Morphologie et comptage différentiel pendant la lactation Les recherches ont porté sur la morphologie et le comptage différentiel des cellules dans le colostrum et le lait de truies. Le nombre total moyen des cellules fut de 1,06 + 0,79 × 109 par litre dans le colostrum et de 1,57 + 0,94 × 109 par litre dans le lait. Il n'y a pas eu de corrélation linéaire entre le stade de lactation et le nombre total des cellules. Six sortes de cellules ont pu être identifiées dans les sécrétions: neutrophils, éosinophiles, lymphocytes, macrophages, cellules épithéliales et cellules sans noyaux. Mis‐à‐part la prédominance des neutrophiles, la présence de nombreuses cellules épithéliales et de cellules sans noyaux semble être une caractéristique essentielle de la sécrétion lactée de la truie. Resumen Células de las secreciones mamarias de cerdas I. Morfología y recuento diferencial durante la lactación Los estudios se refieren a la morfología y al recuento celular diferencial en el calostro y en la leche de cerdas. Las cuantías totales medias importaron en el calostro 1,06 + 0,79 × 109 y en la leche 1,57 + 0,94 × 109 células por litro. No existía ninguna correlación lineal entre el estadio de lactación y el número de células totales. En las excreciones se pudieron identificar los 6 tipos celulares siguientes: neutrófilos, eosinófilos, linfocitos, macrófagos, células epiteliales y células anucleadas. Aparte de la dominancia de los neutrófilos, parece ser que la presencia de numerosas células epiteliales y células anucleadas es una característica esencial de la secreción mamaria d...

“…Os neutrófilos, assim como os macrófagos são responsáveis por fagocitar não apenas os microorganismos como também debris celulares e gotículas de gordura, porém de uma maneira menos eficiente. O neutrófilo também foi o tipo celular predominante encontrado no colostro e leite de fêmeas cobaias (NORDIN; LEE, 1982).…”

“…Poucas células epiteliais foram observadas (0-1%) concordando com a descrição efetuada em ovelhas (LEE; OUTTERIDGE, 1981), porcas (EVANS et al, 1982) e cobaias (NORDIN; LEE, 1982).…”

Existem poucos trabalhos na literatura relativos aos tipos deleucócitos presentes no colostro e no leite de éguas. Recentes trabalhos realizados em animais de produção sugerem que os leucócitos do colostro podem desempenhar um importante papel na transferência passiva de imunidade da mãe para o neonato. Esse estudo teve como objetivo caracterizar a população de leucócitos presente no colostro de éguas clinicamente sadias utilizando a microscopia óptica. As amostras de colostro utilizadas foram provenientes de 20 éguas, 12 da raça Mangalarga Marchador e 8 da raça Quarto de Milha. O tipo celular predominante na maioria das amostras estudadas foi o macrófago, seguida pelos neutrófilos e linfócitos. Esses resultados podem proporcionar um ponto de partida para futuros estudos de investigação sobre o papel dos leucócitos colostrais na transferência de imunidade da égua para o potro.
