高脂日粮模式已广泛应用于鱼类养殖中,但同时也引发了肝脏脂肪过度沉积等问题。二十二碳六烯酸(Docosahexaenoic acid,DHA, 22:6n-3)对鱼类生理及发育具有重要意义。近期,中国农业科学院饲料研究所水产微生物与饲料团队评估了DHA添加比例对鱼类肝脏脂肪的蓄积效应,揭示了作用机制。相关研究成果发表在《Frontiers in Nutrition》
研究发现,在鱼类高脂日...
湖羊热应激相关的生理生化指标筛选
湖羊 热应激 生理指标 生化指标
2020/12/4
为研究热应激对湖羊生理生化指标的影响,将湖羊分别饲养于热应激(2017年8月)和非热应激(2017年12月,对照组)环境中,测定其生理生化指标三碘甲腺原氨酸(T3)含量和甲状腺素(T4)含量。结果表明,热应激显著或极显著改变了湖羊生理生化指标,例如呼吸频率、平均红细胞体积、红细胞压积、平均血小板体积、天门冬氨酸氨基转移酶含量、碱性磷酸酶含量、r-谷氨酰基转移酶含量和高密度脂蛋白胆固醇含量。此外,热...
奶牛性情评定方法及其影响因素分析
荷斯坦牛 性情评分 体况评分
2018/4/16
旨在建立简便可行的奶牛性情评定方法并探究性情在奶牛生产中的重要性,本研究采用两种简便、快捷的性情评分方法,于2016年7-8月在北京地区7个牛场现场评定3 988头处于泌乳期的荷斯坦牛,采用固定模型分析奶牛性情的影响因素及性情对产奶量、体况评分(BCS)的影响。分析表明,两种方法均能显示奶牛性情的差异,且两种性情评分方法均值差异仅为0.04,秩相关检验无显著差异;不同场、胎次、泌乳阶段的奶牛性情评...
为了研究长期或短期饲喂高精料日粮对泌乳期奶山羊瘤胃上皮组织氧化应激和胆固醇代谢的影响,实验选用17只健康的经产泌乳中期关中奶山羊,随机分为3组:饲喂低精料组(对照组,LC,n=5);长期饲喂高精料组(HL, n=7),19周饲喂期;短期饲喂高精料组(HS,n=5),4周饲喂期。实验结束后采集瘤胃组织,用PBS反复清洗,于液氮中速冻后置于-80 ℃冰箱保存。结果显示,与对照组相比,HL和HS组山羊瘤...
