中文摘要 |
用处理造纸废液的资源化产品──精矿浆与尿素混合处理秸杆,可提高秸杆作为家畜饲料的利用率。本实验用绵羊瘤胃内48h干物质消失率(DMdp)作为对家畜可利用程度的指标。用河北涿州市造纸厂的糖矿浆处理的稻草干物质消失率提高了40%,中性洗涤纤维含量降低了22.6%。稻草和玉米杆经糖矿浆尿素混合处理后饲喂绵羊日增重较氨化秸杆分别提高了22.8%和9.25%。 |
英文摘要 |
A new straw feed has been developed by using a mineral saccharide,a filtrate left from straw pulping black liquor after recovering liqnin and chemicals from it,to treat crop stalks mixed with urea,resulting in an increased utility of crop stalks as domestic animal feed. The mineral saccharide was found to be rich in amino acids,raw proteins,essential elements and saccharides,to comply with the national standards (GB 1307891) for feed hygiene,and to enable providing a source of nutrients for domestic animal and erecting straw due to its residual alkalinity. The 48 hours dry matter disappearance (DMdp) in the remen of sheep was used as an indicator of straw availabity for animal.Rice straw had a DMdp increased by 40% and a NDF (Neutral fletergent Fiber) reduced by 22.6%,when tile straw was erected with the mineral saccharide from the Zhuozhou Paper Mill in Hebi Province. By feeding the rice and maize straw,treated with the mineral saccharide,sheep had a dally weight increase by 22.8% and 9.25%,respectively,as compared to those treated with ammonia. |
