Abstract

8 individual feeding experiments served the ascertainment of the consumption performance of ewes in the perinatal phase. In 6 experiments with a total of 176 fertility oriented ewes the daily intake of pelleted straw-concentrate mixtures between the 4th week ante partum and the 6th week post partum was determined. On average the ewes consumed 1701 g dry matter in the last phase of gestation and 2271 g DM during lactation per animal and day. Intense grinding and NaOH-treatment increased feed intake; high straw content, limited duration of feeding and NH3-treatment decreased it. A higher number of lambs had, in the last phase of gestation, a decreasing and during lactation an increasing effect on consumption. Maize silage in the last phase of gestation resulted in very low feed intake. In contra to this, rations of alfalfa hay and maize silage were consumed well during lactation. There were no significant differences due to species or age with regard to consumption performance.

摘要

8项个体饲养试验用于确定母羊围产期的采食性能。在6项试验中,共有176只以繁殖为导向的母羊,测定了产前第4周和产后第6周之间颗粒状秸秆 - 浓缩料混合物的日摄入量。平均而言,母羊在妊娠后期每只每天消耗1701克干物质,哺乳期消耗2271克干物质。强烈研磨和氢氧化钠处理增加了采食量;高秸秆含量、有限的饲喂时间和氨处理降低了采食量。在妊娠后期,较多的羔羊数量对采食量有降低作用,而在哺乳期则有增加作用。妊娠后期的玉米青贮导致采食量非常低。与此相反,苜蓿干草和玉米青贮日粮在哺乳期的采食情况良好。在采食性能方面,品种或年龄没有显著差异。
