概括

卡梅琳娜草可以在羔羊饮食中部分取代草干草,支持生长性能. 这种可持续的料替代品增加了时间,但并没有增加时间.

科学领域:

动物科学动物科学
类动物营养类动物营养
可持续农业可持续农业

背景情况:

越来越多的干旱需要对反动物提供耐干旱的替代料.
卡梅琳娜草 (CS) 是一个潜在的可持续料成分.

研究的目的:

为了评估驼草作为部分替代草干草 (AH) 在灰色Shirazi羔羊的饮食.
评估包括CS在羊羔表现,营养消化能力和行为上的影响.

主要方法:

24只羔羊被养以每公斤0,120或240克干物质 (DM) 的CS代替AH的饮食.
测量了干物质摄入量 (DMI),体重,平均每日取量 (ADG) 和料转化率 (FCR).
分析了营养物质的消化性,小参数 (pH,NH3-N,VFA) 和活动.

主要成果:

在治疗之间没有观察到DMI,FBW,ADG或FCR的显著差异.
有机物 (OM) 和中性清洁剂纤维 (NDFom) 消化率的线性降低随着CS含量增加而发生 (P < 0.05).
鲁米纳的参数基本上没有受到影响,除了乙酸和异酸盐度的增加.
由于更高的物理有效纤维,转和总时间线性增加 (P < 0.01) ,其中包括CS.

结论:

卡梅琳娜草可以作为部分替代草干草的部分替代品,用于羊的成品饮食,最多可达240g/kg DM.
尽管纤维消化能力略有降低,活动增加,但羊羔的表现没有受到损害.
建议进一步研究反动物微生物生态,以阐明潜在的机制.

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
