Hohhot was awarded the title of ＂Chinese Dairy Capital＂. Now dairy industry is one of the pillar industries in Hohhot, with strong driving effect to the development of social economy. However; the sustainable development of dairy industry in Hohhot is threatened by rapid scale expansion and restriction of environmental supporting capacity, In accord with the ideas and requirements of the circular economy theory, this paper analyzes dairy industry pattern from two aspects and establishes the industry system. The dairy industry mainly consists of cow breeding and dairy process. The circular economy mnst set about from the two aspects. For the most part, dairy processing should start from the two most key links, namely packing and water using.展开更多

文摘利用2008-2016年出生的27 444头宁夏地区荷斯坦奶牛生产性能(dairy herd improvement,DHI)数据及体型线性评分数据计算乳脂率(fat percentage,FP)、乳蛋白率(protein percentage,PP)、体细胞评分(somatic cell score,SCS)、305d产奶量(milk yield of 305days,MYD)、初产日龄(age at first calving,AFC)、产犊间隔(calving interval,CI)和体况评分(linear classification scores,LCS)的遗传参数。利用DMU v 6.0软件,采用AI-REML模块结合EM算法并配合多性状动物模型,以季节、场、年份、胎次和动物个体加性遗传效应作为模型的影响因素。计算结果表明,宁夏地区奶牛的FP、PP、SCS、MYD、AFC、CI和LCS的遗传力分别为0.14、0.19、0.19、0.31、0.37、0.10和0.07,同时得出了奶牛不同性状的育种值、遗传相关和奶牛生产性能指数2(China performance index 2,CPI2)值。本研究通过对宁夏地区奶牛DHI数据的深挖和遗传评估,准确地把握了宁夏奶牛群体结构特征,对于奶牛的选种选配、育种规划和选择指数的构建有重要意义。
