| | A lamb grazing system in sainfoin stubble fields was studied from the stand point of view of agricultural energetics. Results from the experiment indicate that the output/input ratio of energy from four treatments of RM, SM, RO and SO were 22.34%, 19.98%, 16.67% and 17.51%, respectively. The ratio of rotational grazing was 1.24 times over that of set stocking. It would be more effective to increase energy input including the input of direct and indirect physiological energy to those Lamb under rotational gr... | | 为了探讨草地农业系统的丰产高效性能,作者通过羔羊轮牧与定牧加不同补饲水平的比较,对红豆草茬地不同利用方式下能量投入的产出差异进行了力能学分析。试验分A(轮牧+混合草料)、B(轮牧+燕麦干草)、C(定牧+混合草料)和D(定牧+燕麦干草)4组。试验期80天。结果表明,4种处理的能量产投比分别为22.3%(A)、19.98%(B)、16.67%(C)和17.50%(D),其中轮牧平均为定牧的1.24倍(P<0.05)。给轮牧系统增加辅助能投入比定牧系统更为经济有效。 | | 文摘来源 | | Tibetan sheep aged 14~15 monthes were used in a 45-day yard finishing trialto observe the effect of urea pellet supplemented with 300 and 400 g per animal per day in basaldiet composed of oat hay and oilseed shell on the growth of the animal.The results showed thatthe daily gain was increased by 75.36%and 91. 32%(148 and 161.56 g vs 84.44 g,fed basaldiet orily)individually,the feed efficiency was increased by 27.09%and 27.97%resp.theeconomic profit of each sheep increased by 6.44 and 4.97 RMB. | | 在由燕麦干草、油菜荚壳组成的基础饲料中,分别添加300g/头·日和400g/头·日的尿素颗粒饲料,对14~15月龄藏羊进行圈饲育肥。经45天饲养,日增重分别为148g和161.56g,比仅喂基础料时(84.44g)分别提高75.26%和91.32%;饲料转化率分别提高27.09%和27.97%;每羊分别多盈利6.44元和4.97元。 | | 文摘来源 | | The yield of Brassica rapa cultivated in Guoluo region at the altitude of 4 000m was 8 133~12 333 kg/hm 2,and the yield of tuber approached to that of oat hay.The results of experiment showed the performance of introduced species tamed in local area was more than that of introduced species that year,and perform ance of purple Brassica rapawas more than that of white Brassica rapa.Therefore it could be planted and extended as juicy fodder. | | 在青南海拔高度近 40 0 0m的地区种植芜菁产量在 8133~ 12 333kg hm2 之间 ,其块茎产量与燕麦干草产量基本一致。试验结果表明当地引进训化品种优于引进品种 ,紫芜菁优于白芜菁。作为多汁饲料适宜在青南牧区推广种植。 | | 文摘来源 | |   | | << 更多相关文摘 |
