    • 摘要: 通过分析不同海拔环境下饲养的湖羊小肠组织学结构的异同,探讨湖羊在高原集约化养殖的可行性。试验在同源同胎次异地繁育饲养的湖羊群中,各挑选40只体重相近的90日龄健康湖羊,分为低海拔组(山东)和高海拔组(青海),常规饲养,试验期150 d结束后每组随机选取6只公羊剖杀采集小肠,采用组织学及图像分析法,对肠绒毛高度、黏膜层厚度、杯状细胞数量、隐窝深度进行观测。结果显示:低海拔组平均日增重显著高于高海拔组(P<0.05),料重比则显著低于高海拔组(P<0.05);低海拔组小肠各段绒毛高度、隐窝深度、黏膜层厚度均显著高于高海拔组(P<0.05);高海拔组小肠各段的杯状细胞数量均显著高于低海拔组(P<0.05)。结果表明:在遗传背景、日龄、饲料营养物质基础相近的情况下,海拔环境的改变使湖羊肠道生理结构发生了细微的变化,导致2组湖羊生产性能上的差异,提示环境差异较大的地区引种后更应加强饲养管理。

    • 摘要: 为了解布氏罗非鱼性腺分化的时间和性腺发育的特点,本研究通过组织学方法观察不同发育时期的布氏罗非鱼(Tilapia buttikoferi)性腺的组织形态结构.结果显示:布氏罗非鱼出膜后的20 d卵巢分化,分化的标志是出现卵巢腔;精巢分化晚于卵巢,分化标志为精巢内形成精小叶;雄性个体在180日龄达到性成熟,而雌性个体240日龄才完全成熟.布氏罗非鱼卵巢发育分为6个时期:卵原细胞期,初级卵母细胞小生长期,初级卵母细胞生长期,初级卵母细胞大生长期,成熟期和衰退期.第Ⅱ时相卵母细胞有多个核仁,出现单层滤泡膜;第Ⅲ时相卵母细胞出现空泡,核仁环状贴核膜排列,后期出现双层滤泡膜结构;第Ⅳ时相卵母细胞出现卵黄颗粒和粗大的核仁;第Ⅴ时相卵母细胞,其核膜溶解,核仁消失,细胞质内充满大的卵黄颗粒,空泡与卵黄颗粒交互排列.在五期卵巢中同时存在Ⅱ、Ⅲ、Ⅳ时相卵母细胞,并且靠近卵巢壁的卵母细胞发育时期要早于中间,布氏罗非鱼产卵类型为非同步分批.布氏罗非鱼精巢为小叶型.

    • 摘要: [Objective] The purpose of this study is to explore the formation and development pattern of muscle fiber and reveal the developmental characteristics of skeletal muscle tissue in fetal period of German Merino sheep.[Method] Three times of D75,D105 and D135 during pregnancy were selected.The body size of German Merino fetal sheep was measured.Longissimus tissue from fetal sheep was collected and subjected to tissue sections and HE staining to count for the fiber number,diameter and density at different developmental stages of feta1 muscle tissue.Fiber type was determined using immunohistochemistry to clarify the number of fast/slow muscle fiber type in dfferent stages of development.[Result] At the period from D75 to D135 of pregnant,the increase of fetal weight was nearly 17 times,the body length and height is nearly 1.5 times.The numbers of muscle fibers in unit area gradually increased to D105 while reach the highest value,and the overall trend first climbed up and then declined.The growth rate of diameter of muscle fibers from D75 to D105 was relatively smooth,but that of D105-D135 obviously increased.In middle stage,the slow muscle (type Ⅰ muscle fiber) was the main type,and the latter was mainly composed of fast muscle (type Ⅱ muscle fiber).[Conclusion] The number of German Merino sheep fetal muscle fiber reached peak at D105,and the number of muscle fiber is almost constant.We found that the pregnant time of 105 days was a critical time window with fiber developmental transformation from muscle hyperplasia to muscle hypertrophy,and made clear the slow muscle (type Ⅰ muscle fiber) was the main type during middle stage,and the latter stage was mainly composed of fast muscle (type Ⅱ muscle fiber).%[目的]探究胎儿期绵羊肌纤维的形成与发育规律,揭示德国美利奴羊胎儿期骨骼肌的组织学生长发育特征.[方法]选择妊娠期第75天(D75)、第105天(D105)和第135天(D135)的胎羊,测定其体长、体高和体质量;采集背最长肌,进行组织切片和HE染色,统计不同发育阶段胎儿单位肌纤维数量、直径和密度;应用免疫组化方法研究不同发育阶段背最长肌中快/慢肌纤维的类型和密度.[结果]随着怀孕母羊妊娠时间的增加,从75~135 d胎儿体质量增长近17倍,体长、体高增加近1.5倍;单位肌纤维数量总体呈先增加后减少的变化趋势,在105 d时单位面积肌纤维数量最高;肌纤维直径于妊娠75~105 d增长幅度较为平缓,105~135 d增长速率明显变大;早中期发育主要以慢肌(Ⅰ型肌纤维)为主,后期发育主要以快肌(Ⅱ型肌纤维)为主.[结论]德国美利奴羊胎儿肌纤维数量在妊娠105 d时达到峰值,且此时肌纤维数量基本恒定,是肌纤维从肌增生转为肌肥大发育的关键时期,早中期发育主要以慢肌(Ⅰ型肌纤维)为主,后期发育主要以快肌(Ⅱ型肌纤维)为主.

    • 摘要: 应用光学显微镜和扫描电子显微镜技术对北方硕螽(Deracantha onos Pallas)6龄若虫、未交配和交配成虫3个时期受精囊的组织学结构进行了比较研究.结果显示,6龄若虫受精囊上皮层细胞处于增殖状态,各种细胞的形态不易区分;未交配成虫的受精囊上皮层细胞已初步分化,分布层次不明显,上皮层端部出现颗粒物;已交配成虫的受精囊分化出上皮细胞、腺细胞和导管细胞3种细胞类型,分布层次明显,颗粒物消失,腺细胞分泌腔呈现多态性.此外,已交配受精囊内表面分布有棘和导管细胞的导管开口,其形态均存在区域性差异.研究表明交配活动可能诱导了腺细胞的分泌活性,在受精囊不同区域腺细胞和棘可能行使不同的生理功能.%The structures of the spermatheca in 6th-instar nymphs,unmated and mated females of Deracantha onos Pallas (Orthoptera:Tettigoniidae) were investigated by light and scanning electron microscopy.The results showed that epithelial cells of the 6th-instar nymphs were undergoing proliferation,and their morphology was not easy to identify.The preliminary differentiation of the epithelial cells could be seen in the unmated adults,but their distribution was not obvious.The granules occurred in the apical cytoplasm of the epithelial layer.In the spermatheca of mated adults,the differentiated cells formed three types of epithelial cells distributed in distinctive layers,and the granules,which appeared in unmated adults,disappeared.The secretory cavities of glandular cells had polymorphism.Furthermore,on the internal surface of the spermatheca from mated females,the shapes of the bristles and the openings of secretory duct were regionally distributed.It is suggested that mating activity may induce glandular cells to produce large amount of secretions.The bristles and glandular cells in varied regions may play different roles and functions in insects.

    • 摘要: This experiment was conducted to investigate the effects of zinc-methionine on egg quality,intestinal morphology and histological structure and cecal microbial flora to determine the scientific doses in laying hens.Five hundred and forty 20-week-old healthy Hyline White laying hens were randomly allocated to 6 groups with 6 replicates per group and 15 birds per replicate.Hens in group Ⅰ were fed a basal diet as the control,and those in group Ⅱ,Ⅲ,Ⅳ,Ⅴ and Ⅵ received the basal diets supplemented with 70,140,350,700 and 1 400 mg/kg zinc-methionine,respectively.The trail lasted for eight weeks.The results showed as follows:Compared with the control group,laying rate,daily egg mass,the ratio of feed to egg were notably increased and unqualified egg rate were significantly decreased (P<0.05),eggshell strength,eggshell thickness,albumin height and haugh unit were remarkably improved (P<0.05),villus height and ratio of villus height to crypt depth were notably increased (P<0.05),the number of Bifidobacteria and Lactobacilli was remarkably increased and the amount of Escherichia coli was notably decreased (P<0.05) in the cecal contents of laying hens in group Ⅱ and Ⅲ,however,laying rate,daily egg mass,the ratio of feed to egg were notably decreased and unqualified egg rate were significantly increased (P<0.01),eggshell strength,eggshell thickness,albumin height and haugh unit were remarkably reduced (P<0.01),villus height and ratio of villus height to crypt depth were notably decreased (P<0.01),the amount of Escherichia coli was extremely increased (P<0.01) and the number of Bifidobacteria and Lactobacilli was notably decreased (P<0.01) in group Ⅵ.Damage occurred in duodenum and ileum of hens in group Ⅵ.The results indicated that dietary supplementation with optimal doses of zinc-methionine upregulated laying performance and egg quality,improved the intestinal morphology,optimized cecal microbiota of laying hens,but continuously improving the supplemental levels would lower its positive effect and even trigger negative effects.According to the quadratic curve fitting model,the optimal supplemental level of zinc-methionine is 50~100 mg/kg in the corn-soybean meal diet of laying hens during the peak period.%本试验旨在研究饲粮中添加蛋氨酸锌对蛋鸡蛋品质、肠道形态、组织学结构及盲肠微生物菌群的影响,以确定蛋氨酸锌在蛋鸡饲粮中的科学用量.选择健康的20周龄海兰白蛋鸡540只,随机分成6个组,每个组6个重复,每个重复15只鸡.Ⅰ组为对照组,饲喂基础饲粮,试验Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ组分别在基础饲粮中添加70、140、350、700、1 400 mg/kg蛋氨酸锌.正试期8周.结果表明:与对照组相比,Ⅱ、Ⅲ组产蛋率和日产蛋重显著提高(P<0.05),料蛋比和不合格蛋率显著降低(P<0.05),蛋壳强度、蛋壳厚度、蛋白高度和哈氏单位显著提高(P<0.05),十二指肠、回肠的绒毛高度和绒毛高度/隐窝深度显著提高(P<0.05),盲肠内容物中双歧杆菌、乳杆菌数量显著增加(P<0.05),大肠杆菌数量显著减少(p<0.05);而Ⅵ组产蛋率和日产蛋重极显著降低(P<o.01),料蛋比和不合格蛋率极显著升高(P<0.01),蛋壳强度、蛋壳厚度、蛋白高度和哈氏单位极显著降低(P<0.01),十二指肠、回肠的绒毛高度和绒毛高度/隐窝深度极显著降低(P<0 01),双歧杆菌和乳杆菌数量极显著减少(P<0.01),大肠杆菌数量极显著增加(P<0.01);Ⅵ组蛋鸡十二指肠和回肠结构发生损伤.由此可见,适量的蛋氨酸锌可提高蛋鸡产蛋性能和蛋品质、改善肠道形态、优化盲肠微生物区系,但继续提高添加水平会降低其对蛋鸡产蛋性能、蛋品质和肠道健康的正面效应,甚至会引起负面效应.根据二次曲线拟合模型得出蛋氨酸锌在20~27周龄蛋鸡玉米—豆粕型饲粮中的适宜添加水平为50~100mg/kg.
