黄羊胃肠组织形态学研究 总被引:5,自引:0,他引:5
采用石蜡切片方法对健康成年黄羊胃,肠进行了组织形态学观察。结果表明,瘤胃,网胃和瓣胃的胃壁构造基本相同。粘膜上皮都是复层扁平上皮,浅层细胞角化,瘤胃粘膜上形成许多大小不等的舌状乳头。无粘膜肌层;网胃粘膜形成许多皱襞。在皱襞上和网孔底上有许多圆锥状乳头。 相似文献

对51头黄羊的胃进行了形态结构的研究。整个胃组织质量占体质量的比率为2.74%~2.89%。成年雄性、成年雌性、幼年雄性和幼年雌性中的比率分别为(2.74±0.11)%,(2.83±0.09)%(2.82±0.14)%和(2.89±0.20)%。瘤胃最大,占整个胃组织质量的72%~76%其次是网胃(9%~10%)、皱胃(8%~10%)和瓣胃(5%~6%)、除瘤胃与体质量呈线性正相关外,其它3个分胃与体质量呈线性负相关。瘤胃表面扩张系数( SFF)值为 8.52.瘤胃粘膜乳突密度为 89。黄羊胃分四层结构:粘膜层、粘膜下层、肌层和浆膜。前胃粘膜上皮都由复层扁平上皮细胞组成。瘤胃缺乏粘膜肌层、网胃肌层较厚。黄羊前胃无腺体.仅皱胃分布大量腺体。胃底腺主要由主细胞、壁细胞和颈粘液细胞构成、前胃的肌层比皱胃发达。从黄羊复胃形态结构特征分析、黄羊属于混饲者。 相似文献

The food availability, composition of the diets and selective grazing of the Mongolian gazelle (Procapra gutturosa) were studied in Hulunber Grassland in Nei Monggol. The food availability of Mongolian gazelle showed seasonal changes. The
plant biomass was higher in spring and summer than that in autumn and winter. The fecal compositions of the gazelle demonstrated
that fibrous parts occupied 62.4%, 74.8%, and 66.0% in spring, autumn, and winter, respectively. The Mongolian gazelle preferred
to grazeCompositeae, Leguminosae, Allium spp. and other forbs in spring and autumn, while the grasses, such asAneurolepidium chinense andStipa spp. were selectively feeding in winter.

研究测定了14种黄羊主要饲料植物和51头黄羊瘤胃内食物的粗蛋白质、中性洗涤性纤维、酸性洗涤性纤维、酸性洗涤性木质素、中性洗涤性纤维灰分、酸性洗涤性纤维灰分、纤维素和半纤维素的含量。结果表明,各类饲料植物中营养成分的含量存在显著差异(P〈0.05),而且具有明显的季节性变化:春季粗蛋白质的含量最高,冬季最低。洗涤性纤维和木质的季节变化则相反,春季最低,冬季最高。瘤胃内食物的营养成分季节变化模式与饲料植物相似,同一时期,瘤胃内食物的营养成分要高于饲料植物。中性洗涤性纤维与粗蛋白质呈显著的线性负相关性,与其它营养成分则是显著的线性正相关性。 相似文献
