调查了我省肉鸡生产状况,十多年来,我省肉鸡业从无到有,从小到大,饲养的品种有明星、红宝、京黄、艾维茵等。以明星和京黄较为适宜在我省高寒、缺氧的环境条件下生产,从1993年到1995年,三年共推广出栏良种肉鸡324.32万只,并探索出一套适宜我省实施的肉鸡生产配套技术,说明我省发展肉鸡生产的前景是广阔的 相似文献

丝绸产品是我省传统的出口商品,在全国丝绸出口中,我省的出口总额近年来均排在前三位。广东丝绸在繁荣我国的丝绸事业,发展经济,为国家多出口创汇作出了很大的贡献。但是,与其他省市相比,我省的生丝质量却是较低的,与我省的出口地位很不相称。分析影响我省生丝质量 相似文献

山羊肉的生产与营养价值 总被引:1,自引:0,他引:1
产肉是山羊的主要性能。世界的山羊增长率虽然比其它反刍家畜快,但山羊肉仍不能满足日益增长的人口的需要,我国也不例外。因此特别需要加快山羊肉生产的发展。我国山羊肉的生产是分散在农村的。在生产山羊肉时,需要注意山羊的胴体重。总的可食率和总的有商品价值率。了解山羊肉的营养价值才能更好地发展和利用山羊肉。山羊肉是一种高蛋白、低能量的食品。山羊肉蛋白质中的各种必需氨基酸含量充足,其含量占氨基酸总量的一半左右。与理想蛋白质所含的必需氨基酸相比,有四种氨基酸含量接近理想蛋白,其余的也都相差不大。蛋白质的生物价虽不如黄牛,但比水牛高。山羊脂肪的沉积主要在内脏,皮下脂肪比较少。肉中所含的脂肪酸,以不饱和脂肪酸为多,不饱和脂肪酸对人的营养有好处。亚油酸是人体摄入能量所必需的。山羊肉的胆固醇含量也较低。肌肉中Ca的含量比牛肉少,而P的含量却比牛肉多,特别是小肠中的P含量几乎是牛的五倍。维生素B1和B2的含量山羊肉也比牛肉高 相似文献

Three surveys and a sensory evaluation of goat meat were conducted in Japan to examine the current needs and future possibilities of goat meat consumption. The experimental results of the present study lead us to conclude the following: (i) improving the smell of goat meat and combining the sale of goat meat with recipes may increase goat meat demand among housewives; (ii) it seems to be difficult to disseminate Okinawa goat cuisine to non‐Okinawa residents because of the typical odor of goat meat, which is unlikely to be preferred by the public; (iii) the “chewiness” of goat meat is rated highly by young participants according to a sensory evaluation, and loin meat is rated highly compared with hind leg meat; and (iv) there is a rapidly increasing interest and a tremendous purchasing drive towards goat meat among university students. However, these facts call for further investigation of the goat meat demand in Japan. The following three further experiments are needed to solve this issue: (i) breeding to improve the taste of goat meat; (ii) expanding the marketing of goat meat combined with the invention of Japanese‐style goat recipes and tie‐in sales supermarkets; and (iii) implementing further sensory analyses to compare goat meat with other meat and carrying out market analysis in Japan. 相似文献

波尔山羊对我国本地山羊杂交改良的初步效果 总被引:1,自引:1,他引:0
目前我国山羊无论存栏数还是产肉量均居世界首位,但各地方品种众多,与世界优良肉用山羊相比普遍体重小、生长慢.从1995年以来我国引进了著名肉用山羊--波尔山羊,各地相继开展了波尔山羊对本地山羊的杂交改良,都取得了显著的效果,杂交后代在生长速度及产肉性能方面都有很大的提高,为加速我国肉用山羊业的发展开创了新的途径. 相似文献

In order to understand the regularities of A-FABP gene expression in Guizhou native goats,and to establish the theoretical basis of molecular marker assisted selection for meat quality traits,β-actin gene was used as control,expression levels of A-FABP gene in livers,kidneys,hearts,lungs,longissimus muscle,semimembranosus muscle and subcutaneous fat of Qiandongnan small Xiang goat,Guizhou White goat,Guizhou Black goat,Qianbei Ma goat and Nanjiang Yellow goat were detected by Real-time fluorescence quantitative PCR.The results showed that A-FABP gene was expressed in all 7 tissues of 5 goat breeds,and the expression levels of A-FABP gene mRNA were all high in subcutaneous fat of 5 goat breeds;In subcutaneous fat,which was the main tissue of A-FABP gene expression in Guizhou native goats,and in longissimus muscle and semimembranosus muscle,which were directly associated with meat production property,A-FABP gene mRNA levels were all high in Qiandongnan small Xiang goat.The results suggested that the tissue distribution patterns of A-FABP gene mRNA in Guizhou native goat breeds were similar to each other.The excellent meat quality of Qiandongnan small Xiang goat might be related with the high expression levels of A-FABP gene mRNA in it's subcutaneous fat,longissimus muscle and semimembranosus muscle. 相似文献

为弄清贵州地方山羊脂肪细胞型脂肪酸结合蛋白(adipocyte fatty acid-binding protein,A-FABP)基因mRNA的表达规律,奠定肉质性状分子标记辅助选择的理论基础,试验以β-actin基因为内参,应用实时荧光定量PCR技术检测黔东南小香羊、贵州白山羊、贵州黑山羊、黔北麻羊和南江黄羊共5个山羊品种心脏、肝脏、肺脏、肾脏、背最长肌、半膜肌及皮下脂肪7个组织器官中A-FABP基因的表达.结果表明,5个山羊品种7个组织中都有A-FABP基因表达,且5个品种中皮下脂肪A-FABP基因的表达水平都较高;在贵州地方山羊A-FABP基因表达的最主要组织--皮下脂肪,以及在与产肉性能直接相关的组织--背最长肌和半膜肌中,黔东南小香羊A-FABP基因mRNA水平都较高.结果提示,贵州地方山羊A-FABP基因mRNA的组织分布模式相似,黔东南小香羊的优良肉质特性或许与其皮下脂肪、背最长肌和半膜肌中A-FABP基因的高表达有关. 相似文献
