1Estimation of herbage intake and digestibility of grazing sheep in Zhenglan Banner of Inner Mongolia by using n-alkanes显示文摘To reveal the seasonal dynamics of herbage intake, diet composition and digestibility and clarify the relationship of those with herbage nutrient and botanical composition of grazing sheep in Zhenglan Banner of Inner Mongolia, the n-alkane technique was used to test in sheep grazed during June, August and December. The results showed that the sheep mainly ate Fringed sagebrush, Stipa krylovii and Carex in proportions of 33.5,17.9 and 21.2%, respectively, in spring. In summer, the sheep consumed cleistogenes,Potentilla tanacetifolia, Thyme, etc; the intake of Fringed sagebrush, Carex and Stipa declined. In winter,Fringed sagebrush accounted for 50.1% of herbage intake, and the intakes of Cleistogenes and Stipa krylovii increased to 15.3 and 18.4%, respectively. Herbage intake by the sheep in spring was 1.8 kg DM/d, and digestibility was 71.4%. Herbage intake and digestibility decreased slightly to 1.7 kg DM/d and 68.4%during the summer, respectively and decreased significantly to 1.2 kg DM/d and 36.4% in winter. There were significant correlations between diet composition and CP content in winter, diet composition and botanical composition in summer. A highly positive correlation between herbage intake and digestibility was observed in grazing sheep.Changqing Li Alatengdalai Shuyuan Xue Atsushi Tajima Naoto Ishikawa 2015Animal Nutrition2015,,4:9
2Effects of Molasses-Urea Supplementation on Weight Gain,Ruminal Fermentation and Major Microbe Populations of Winter-Grazing Sheep in Inner Mongolia显示文摘The present experiment was conducted to determine the effects of Molasses-Urea Supplementation(MUS)on weight gain,ruminal fermentation and major microbial populations in sheep on a winter grazing regime in Inner Mongolia.Total 40 sheep,allowed free consumption of MUS after grazing,served as a treatment group,while 30 sheep,fed only by pasture grazing,served as a control group.Ruminal fermentation parameters,consisted of p H,Bacterial Crude Protein(BCP)and ammonia nitrogen(NH_3-N)were measured.In addition,numbers of fi ve symbiotic bacteria were investigated.The results showed as follows:the average daily weight gain,concentration of NH_3-N and numbers of protozoa were signifi cantly higher(p<0.05)in the treatment group than those in the control group.Contrastingly,no signifi cant difference was found in BCP concentration and p H between the two groups.At the end of the experiment,the populations of Selenomonas ruminantium,Anaerovibrio lipolytica,Fibrobacter succinogenes,Ruminococcus fl aveciens and Ruminococcus albus in the treatment group were signifi cantly higher than those of the control group(p<0.05).These results demonstrated that greater weight gain could be induced during winter in Inner Mongolia by improved nutritional status through promotion of microbial populations using urea and sugar.Li Chang-qing Alatengdalai Xue Shu-yuan Atsushi Asano Atsushi Tajima Naoto Ishikawa 2017Journal of Northeast Agricultural University(English Edition)2017,24,1:3
