本文叙述了保存云藻和结条藻作为家畜饲料的初步实验，并将分析结果列成表格。用SO2气体处理后再排除空气，其化学成分变化不大，保存效果良好。藻类可以在不接种或添加可发酵碳水化合物的情况下青贮。化学变化的程度取决于收获藻类的季节；然而，在这方面，瘤状藤蔓的变化比云藻少。消化率试验是有计划的，但不得不放弃，因为可用的羊不会接受青贮藻类。进行了实验室和中试试验。当使用添加20%氯化钠的海水时，海藻被保存下来，但其成分和营养成分发生了重大变化。在海水中加入保存量足够的杀菌剂，也会使海藻死亡。用二氧化硫处理海藻，排除空气，得到了很好的保存效果。不添加任何添加剂的青贮海藻具有良好的乳酸发酵效果。营养物质的保存取决于海藻的原始成分，因此也取决于收获海藻的季节。提出了消化率试验，但由于该品种的羊不吃青贮饲料，因此无法进行消化率试验。t.d.贝尔。参见摘要3340、3370-72、3376、3424、3425、3505、3625-28、4058、4520。
Preliminary experiments on the preservation of Laminaria cloustonii and Ascophyllum nodosum as possible feeding-stuffs for farm animals, are described and the results of analyses are tabulated. Little change in chemical composition occurred when the fresh algae were treated with SO2 gas followed by the exclusion of air and preservation was satisfactory. Algae can be ensiled without inoculation or the addition of fermentable carbohydrates. The extent of the chemical changes occurring depends on the season of harvesting the algae; Ascophyllum nodosum, however, varies less than does Laminaria cloustonii in this respect. Digestibility trials were planned but had to be abandoned because the sheep available would not accept the ensiled algae.-M.P.Laboratory and pilot scale experiments were made. When sea water with 20 per cent. NaCl added was used the seaweed was preserved, but there were major changes in composition and loss of nutrients. The addition of bactericides to sea water in sufficient quantity for preservation killed the seaweed also. Good preservation was obtained by treating the seaweed with sulphur dioxide and excluding air. Seaweed ensiled without any addition gave a good lactic acid fermentation. The conservation of the nutrients depended on the original composition of the seaweed and therefore on the season at which it was harvested. Digestibility trials were proposed but could not be made because sheep of the breed available would not eat the silage. T. D. Bell.
