“…In the current study, IGF-I concentration in goat and lyophilized bovine colostrum was low, which may be responsible for the absence of differences in the enteric histomorphometry features between the colostrum sources. Similar results were found in villi density in goat kids fed goat or lyophilized bovine colostrum (Moretti et al, 2012a). Corroborating these results, Bühler et al (1998) and Pauletti et al (2007) did not find changes in the intestinal morphometric characteristics of calves ingesting different amounts of IGF-I.…”

“…In the present study the goat kids' intestinal histomorphometry was unaffected by different sources of colostrum, goat or lyophilized bovine. Similar to the results observed in this study, Moretti et al (2012a) using scanning electron microscopy, did not verify morphological differences in the villi of goat kids fed goat or lyophilized bovine colostrum.…”

“…The same feature was found in calves by Blättler et al (2001), Bittrich et al (2004), andSauter et al (2004). In this segment, in the first hours of goat kids' life it is possible to verify enterocytes containing vacuoles filled with colostrum and IgG immunostaining that are related with intense activity of IgG uptake during the passive acquisition period (Moretti et al, 2012a;Nordi et al, 2012). The enteric and absorptive capacity could be related with villus height, volume and density of the mucosa surface.…”

“…Using scanning electron microscopy technique, Moretti et al (2012a) investigated morphological characteristics of enteric tissues of goat kids fed lyophilized bovine colostrum during the period of passive immunity acquisition. The authors observed that in the first four days of goat kids' life the small intestine structure was unaffected by different sources of colostrum, goat or lyophilized bovine, and by the replacement of fetal enterocytes, which are able to absorb macromolecules, by adult-type ones.…”

Enteric histology of newborn goat kids fed lyophilized bovine colostrum (LBC) was studied. At 0, 7, and 14 h of life 15 male newborns received 5% of body weight of lyophilized bovine colostrum and 14 male newborns goat colostrum (GC), both with 55 mg/ml of IgG. Samples of duodenum, jejunum, and ileum were collected at 18, 36, and 96 h of life for analyses of villus height, crypt depth, muscle layer thickness, partial volume of the absorptive mucosa (Vv), density of the absorptive mucosa (Sv), and quantification of goblet cells. Three animals were sampled without colostrum intake (0 h). The histomorphometry was not different between GC and LBC in all segments. In the jejunum, the villus height differed in sampling times (36 h > 0 h and 18 h). The maximum villus height was observed in the jejunum. In the jejunum, crypt depth differed in the sampling times (96 h > 0 and 18 h). Interaction between intestinal segment and sampling times was observed to crypt depth (duodenum 18 h > jejunum 18 h and duodenum 96 h > ileum 96 h). In the ileum, the muscle layer thickness differed in the sampling times (36 h > 0 and 18 h and 96 h > 0 h). The greatest thickness of muscle layer was observed in the duodenum and at 96 h the muscle layer was thicker than at 18 h. The ileum showed the highest Vv at 36 h. The Vv was the highest in the jejunum and higher at 36 h than at 96 h. In the jejunum, an interaction between the treatment and sampling times to goblet cells number (LBC 18 h < GC 18 h and GC 96 h > LBC 96 h) was observed. The ileum showed the greatest number of goblet cells. The ingestion of lyophilized bovine colostrum did not determine any consequences for enteric histology in the first 4 days of goat kids' life.

“…Gut closure is a gradual process, beginning around 12 h post-partum and ending around 24 h post-partum [1,2]. Moretti et al [29] observed vacuoles containing colostral Ig in jejunal epithelial samples taken from goat kids at 0 and 18 h of age, but not in samples taken at 36 and 96 h of age. The later samples were collected after both pinocytosis and transcellular transfer of large molecules ended.…”

Intestinal absorption of immunoglobulins is critical for health and survival of newborn calves because there is no transfer of immunoglobulins in utero. The objective of this study was to determine if feeding beef cows Se-enriched alfalfa hay during the last trimester of gestation improves passive transfer of ovalbumin (OVA), a surrogate protein marker for IgG absorption. Control cows (n = 15) were fed non-Se-fortified alfalfa hay (5.3 mg Se/head daily) plus a mineral supplement containing inorganic Se (3 mg Se/head daily). Med-Se (n = 15) and High-Se cows (n = 15) were fed Se-biofortified alfalfa hay (27.6 and 57.5 mg Se/head daily, respectively); both groups received mineral supplement without added Se. Calves were randomly assigned to receive orally administered OVA at 12, 24, or 36 h of age. Calves that received their oral dose of OVA at 12 h of age had higher serum OVA concentrations across the first 48 h of life if born to High-Se cows compared to calves born to Control cows (P = 0.05), with intermediate values for calves born to Med-Se cows. Our results, using OVA as a model for passive transfer, suggest that if calves do not receive adequate colostrum to reach maximum pinocytosis, then supranutritional Se supplementation in beef cattle may improve passive transfer in their calves, if calves receive colostrum within the first 12 h of age.

The object of this study was to describe the prenatal development and histochemical properties of mucins in the sheep gastrointestinal tract. To determine changes in the mucin profile, the sections were stained with specific histochemical stains for carbohydrates. While neutral and mixed mucins were observed in the superficial epithelial cells of the abomasal pyloric region, acidic mucins were detected in the secretory ducts and corpus of the glands. Acidic mucins consisted predominantly of sialomucins. In the duodenal villi, the number of goblet cells containing neutral mucins increased toward the end of gestation, whereas Brunner's glands contained acidic mucins until the 95th day of gestation and both acidic and neutral mucins thereafter. The jejunal goblet cells contained either acidic, neutral, or mixed mucins. Goblet cells containing acidic mucins, which were mainly localized to the ileal crypts and villi, mostly contained sulfated mucins. While villi were observed in the proximal colon until the 115th day of gestation, later the typical crypt structure emerged. During the period in which the villi were found in the proximal colon, the goblet cells containing sulphomucins were predominant, whereas the goblet cells containing sialomucins were predominant after the typical crypt structure was formed. In conclusion, gastrointestinal mucins may be involved in the formation of meconium during the prenatal period, and acidic mucins may contribute to the strength of the intestinal barrier against pathogens and digestive enzymes, as the barrier is not fully functional after birth.
