Intestinal histology of Santa Ines lambs fed bovine or ovine colostrum

摘要: The aim of this study was to investigate histology characteristics in the small intestine Santa Ines lambs fed bovine or ovine colostrum. At 0 and 6 h life, 12 newborn received 250 ml first milking colostrum (BC) another animals (OC). Samples duodenum, jejunum ileum were collected at 24 72 life. Six sam - pled birth, without intake (0 h). histomorphologic analysis revealed differences between BC OC groups segments. group had higher amounts colostrum-filled vacuoles intestinal epithelium compared latter a number empty vacuoles. However, life both end absorption. Regardless treatment, apical nuclei mainly observed villi enterocytes basal cytoplasm presence An interaction treatment period villus height crypt depth (P < 0.05). In segment, showed lowest (710.37 ± 115.79 µm) while larger (883.79 207.24 than (791.43 129.19 Lambs from deepest crypts (157.15 41.81 µm), followed by (100.08 23.40 (84.89 21.10 ingestion ( P 0.0%). effects on 0.05), deeper (92.67 21.47 83.12 13.85 µm, respectively). histological changes related did not apparently determine any consequences for enteric physiology. Thus, results concerning histologic histomorphometric aspects confirm possibility successfully using as substitute lambs.
