It was soon obvious that the little german shepherd crossbreed would be a large dog - - , too large to continue sharing a doghouse with tex and the yellow cat 没多久就看得出这只小德国杂种牧羊狗会长成一条大狗，大到不能再和特克斯及黄猫同享一间狗屋。
Although this kinds of drought - resistance germplasm have a low absolute yield , their fertility and stability of yield under drought and infertile condition preceded crossbreed 这类地方种质的绝对产量不高，但其稳产性和在干旱贫瘠条件下的丰产性优于杂交种。
20 crossbred beef cattle were divided into 2 groups in order to study the effects of chinese herb medicine additive on their performance and blood biochemical parameters 摘要选用20头杂交架子牛，随机分2组，研究日粮中添加中药饲料添加剂对肉牛生产性能和血液指标的影响。
Efforts to impregnate the two purebred washington rabbits have been unsuccessful so far , he said . next month , biologists should know how many females are pregnant and how many crossbred babies will be born this year 下个月，生物学家就将得知，该计划中有多少雌性侏儒兔已经怀孕以及今年将诞生多少杂交的兔宝宝。
Unlike the traditional crossbreeding of plants , genetic modification holds the potential for transferring specific traits without changing others , like the distinctive flavor of a pinot noir or chardonnay grape 和传统的植物间杂交不同，遗传修改的方法在移植某些特定性状时，不会改变其它特性，就像能保留黑比诺或者夏敦埃葡萄酒特有的香味。
The last two columbia basin rabbits , both offspring of the original captured rabbits , are at the portland zoo . the fate of the isolated species now rests entirely in a crossbreeding program with the closely related idaho pygmy rabbit 而目前仅存的两只雌性纯种哥伦比亚盆地侏儒兔都是那些最初被捕获的侏儒兔的后代，它们也生活在该动物园内。
That is because only large firms have been able to afford the supercomputers needed to mutate and crossbreed large virtual genomes ? and then simulate the behaviour of their offspring ? for perhaps 20m generations before the perfect design emerges 那是因为，一直以来仅有大型企业能负担得起所必需的超级计算机，其用途是变化并杂交大型的虚拟基因组? ?接着模拟它们后代的行为方式? ?而可能要生成2000万后代才能获得完美的设计。
That is because only large firms have been able to afford the supercomputers needed to mutate and crossbreed large virtual genomes ? and then simulate the behaviour of their offspring ? for perhaps 20m generations before the perfect design emerges 因为只有那些大公司才能负担得起费用来使用必须由超级计算机来进行的对大型虚拟染色体进行变异和杂交- -以及随后对这些染色体后代行为模拟- -在完美的设计浮现之前，可能需要经历2000万代。
Methods 24 crossbreed canine were alloted randomly into four groups : xylazole general anesthesia ( group i ) , ketamine general anesthesia ( group ii ) , combination anesthesia of xylazole and ketamine ( groupiii ) , epidural anesthesia with procaini hydrochloridi ( group iv ) 方法24只杂种土犬随机分为4组：静松灵麻醉组(组) 、盐酸氯胺酮麻醉组(组) 、静松灵与氯胺酮复合麻醉组(组) 、盐酸普鲁卡因硬膜外腔麻醉组(组) 。
Directed on the present situation and existing problems in boosting beef cattle industry based on the yellow cattle improvement in china , the review indicated that several relationships , such as integration of individual households and large scale cattle farms , integration of yellow cattle improvement , crossbreeding , breed conservation and utilization , integration of high grain diet intensified fattening and low grain diet economic fattening , should be handled properly ; and the requirements of profitable cattle industry for increasing reproductive survive rate , using hybrid vigor and improving the weight gain , the main factors affecting economic return of large scale cattle farms and the technology level improvement in cattle industry were duiscussed as well 本文就近来我国以黄牛改良为特点的肉牛业蓬勃发展现状与存在问题，指出应处理好养牛经营形式千家万户与规模牛场相结合、黄牛肉用与肉役兼用相结合、黄牛改良选育与杂交、保种及利用相结合、高精料强度肥育与低精料适度育肥相结合等几个问题；并就提高养牛经济效益对提高繁殖成活率、充分利用杂种优势、提高日增重的要求和影响规模牛场经济效益的主要因素及如何提高养牛科技水平等问题提出探讨。
