“…According to PIETRZAK et al (2007), ghrelin may delay the closure of the intestinal barrier in newborns and, in this way, facilitate the transfer of the colostrum and milk proteins into the organism. In addition, by stimulating food intake, motor activity of the gastrointestinal tract and liberation of the growth hormone, ghrelin enhances body weight growth and plays an important role in the maintenance of energetic homeostasis (YOKOYAMA et al 2005;KOTUNIA & ZABIELSKI 2006;PIETRZAK et al 2007;ZABIELSKI 2007). In the present study, the content of total and active ghrelin in the blood of piglets directly after birth amounted to 112.65 and 10.52 pmol l -1 , respectively.…”

The aim of the study was to determine the changes in the content of major proteins, glucose and selected hormones in the blood of piglets during the first 7 days of neonatal life. The study involved an entire litter of eight newborn piglets of F1 hybrids (Polish White Large x Polish Landrace) delivered from one sow in the second gestation. In blood samples collected directly after parturition (before colostrum intake), in the 12 JD , 24 JD and 48 JD hour and in 7 JD day of life, the content of total protein and its fractions, glucose concentration and the level of insulin, T ! (total and free), T " (total and free), leptin, resistin and ghrelin (total and active) was determined. In the blood serum of newborn piglets a low content of total protein, albumins, gamma globulins and a high share of alpha-and beta globulins was found. In the 12 JD hour of life, after colostrum intake, a significant (P<0.05) increase in the content of total protein, albumins, beta-globulins and a rapid increase of gamma globulins as well as decrease of alpha-globulins level were observed. In the consecutive periods of postnatal life a significant (P<0.05) decrease of total protein, beta-and gamma globulins as well as a steady increase in the content of albumins in the blood serum of piglets was observed. The content of glucose, insulin, leptin, resistin and ghrelin in the blood serum of neonates increased significantly (P<0.05) after colostrum intake. During the successive experimental periods a progressive increase (P<0.05) of glucose and T ! as well as systematic decrease of insulin, T " , ghrelin and resistin in the blood serum was observed as compared to the 12 JD hour of life.

“…Moreover, a large subset of OXA-positive cells in the stomach also contains gastrin and this confirms our finding, that also in neonatal dogs these cells may contain more than one peptide and that these substances may act synergistically, answering to luminal stimuli, to check the digestive functions both acting in synergism in the control of muscular or secretory functions and favouring the secretion of the other peptides (Dall'Aglio et al, in press;Kirchgessner, 2002). Furthermore, in neonatal animals the co-expression of orexin A with gastrin and serotonin in the enteroendocrine cells could find an explanation in the possible involvement of orexin in gastrointestinal development (Zabielski, 2007).…”

The presence and distribution of cells positive to orexin A (OXA) and to orexin type 2 receptor (OX2R) were investigated in the gastrointestinal tract of neonatal dogs by means of immunohistochemical techniques. The orexin A-positive cells were identified with some of the endocrine cells in the stomach and in the duodenum; they were both of the open and closed type and were lacking in the large intestine. In the stomach, a large subset of orexin A-positive cells also showed gastrin-like immunoreactivity while, in the duodenum, many of them seemed to store serotonin. The orexin type 2 receptor-positive cells were evidenced all along the gastrointestinal tract examined, also in the large intestine, and they showed the same morphological characteristics as those positive to orexin A. Moreover, the immunohistochemical techniques revealed intense positivity for both orexin A and orexin type 2 receptor in the neurons and fibers of the enteric nervous system. A large subset of orexin A-positive neurons seemed to store substance P

“…by a low capacity to secrete enzymes (Biernat et al, 1999). The proteolytic and lipolytic activities of the brush border enzymes of enterocytes are also low (Zabielski, 1998(Zabielski, , 2007. Due to the immaturity of the digestive system, the role of these vacuoles is to actively participate in the digestion of the nutrients of colostrum and milk (Baintner, 1986).…”

“…Clarke and Hardy (1971) observed enterocytes with giant vacuoles in the week 3 of life of the piglets. Discrepancy between studies results may be caused by many factors, such as differences in the diet of the sows in the final period of pregnancy and lactation, creep feeding of piglets, as well as the breed of animals (Zabielski, 2007). When the rates of development of the mucous membranes were compared between piglets of the Sus scrofa domestica and a pig and wild boar hybrid (Sus scrofa domestica/Sus scrofa), the pig/wild boar hybrid was found to exhibit a more dynamic development of its intestinal mucosa (Skrzypek, 2007b).…”
