新疆黑蜂故事馆坐落于新疆伊犁河谷东部尼勒克县种蜂场,这里是天山深处著名的唐布拉草原,也是新疆黑蜂保护区。1957年8月,根据全国第一次养蜂工作会议精神,为了加快发展“新疆黑蜂”种群,新疆农业厅批准在尼勒克县建立种蜂繁育场并延续至今。2010年,伊犁百信草原蜂业有限责任公司投资建设天山黑蜂产业生态园(黑蜂庄园),庄园占地1500亩,计划投资1.5亿元。 相似文献

广西是全国少数几个产荔枝、龙眼蜜的省区之一.荔枝、龙眼蜜的丰歉,决定着当地养蜂收益的盈亏,也左右着全国荔枝、龙眼蜜的价格走势.下面,笔者就2008年广西荔枝、龙眼蜜生产和市场前景、价格走势作个人分析,以期对蜂友有所参考. 相似文献

爬蜂是一件麻烦事,它会削弱群势,降低生产效果.对于三类非传染性爬蜂,只要在饲养管理中加以关注,即可避免或减轻. 1 早春扩巢太快,蜂群哺育不良造成的爬蜂 症状 这类爬蜂出现在春繁后期或油菜花前期.爬蜂体色正常,体表鲜亮,试飞时振翅而不能起飞.掉在地面上的爬蜂不久即振翅微弱,多数聚集到蜂箱附近的枯枝杂草上冻死.爬蜂常因外界气温较低受冻而拉出无恶劣气味的黄色粪便. 相似文献

为了了解转地蜂场的发展情况,2011~2012年对浙江省缙云县80家转地蜂场进行蜂场组织结构、人文素质及组织化程度调查.结果显示,80家转地蜂场全部是一户一家的家庭结构专业化养蜂场.蜂场以2~4人为主,平均每人饲养52群意蜂.蜂农平均年龄38.5岁,以青壮年为主,适应转地蜂场高强度劳动要求.蜂农文化程度以初中学历为多数,小学、初中、高中的比例约为1∶12∶1.蜂农组织化程度达76.25%~82.5%.上述结果表明,转地蜂场是一种能使养蜂业可持续发展的模式.调查中还发现,蜂协、蜂农专业合作社是组织蜂农、普及科学技术、提高蜂农素质、确保蜂产品安全、增加蜂农收入的好组织,具有推广意义. 相似文献

应用电感耦合等离子-质谱技术(ICP-MS),建立饲料中钠、镁、铬、锰、铁、铜、锌、砷、硒、镉和铅等元素的测定方法。对饲料样品的前处理方法、仪器工作参数和11种元素标准曲线进行优化;并以加标回收、分析方法比对和重复测试说明方法的准确性和精密性。方法在0~1 000 ng/ml范围内线性良好,仪器检出限为0.557 7~5.072 ng/ml,具有良好的精密度,其回收率在88.1%~104.4%之间,相对标准偏差小于5.0%。同时与原子吸收和原子荧光方法进行比对,测定结果相近。所建立的方法简单、快速,可替代原子吸收和原子荧光方法测定饲料中的11种金属元素,为饲料的质量控制提供理想的元素分析方法。 相似文献

In experiment 1, 6 pregnant mares received a concentrate that contained a trace mineral premix that provided 14.3 mg Cu, 40 mg Zn, 28 mg Fe, 28 mg Mn, 0.08 mg Co, 0.16 mg I, and 0.16 mg Se/kg concentrate (group A). Seven mares received the same concentrate plus 502 mg Zn and 127 mg Cu once daily (group B). No differences (P > .05) in foal growth data, or Cu, Zn, and Fe concentrations of mare milk, mare serum, or foal serum were observed. In experiment 2, 6 pregnant mares received the same concentrate as group A (group C), and 8 mares received the same concentrate fortified with 4× the trace mineral premix (group D). Group C mares had higher serum Zn concentration at 1 day (P < 0.01) and 56 days (P < 0.04). Group C mares had higher milk Fe concentration at 28 days (P < .01), and group D mares had higher milk Cu concentration at 56 days (P < .01). Group C foals had higher serum Cu concentration at 14 days (P < .03). The results from this study provide no evidence to indicate that supplementing late gestating and lactating mares with higher dietary trace mineral levels than those recommended currently by NRC has any influence on foal growth and development, or on the Cu, Zn, and Fe concentrations of the mare milk, mare serum, or foal serum. 相似文献

Breed differences for weight (CW), height (CH), and condition score (CS) were estimated from records (n = 12,188) of 2- to 6-yr-old cows (n = 744) from Cycle IV of the U.S. Meat Animal Research Center's Germplasm Evaluation (GPE) Program. Cows were produced from mating Angus and Hereford dams to Angus, Hereford, Charolais, Shorthorn, Galloway, Longhorn, Nellore, Piedmontese, and Salers sires. Samples of Angus and Hereford sires were 1) reference sires born from 1962 through 1970 and 2) 1980s sires born in 1980 through 1987. The mixed model included cow age, season of measurement and their interactions, year of birth, pregnancy-lactation code (PL), and breedgroup as fixed effects for CW and CS. Analyses of weight adjusted for condition score included CS as a linear covariate. The model for CH excluded PL. Random effects were additive genetic and permanent environmental effects associated with the cow. Differences among breed groups were significant (P < 0.05) for all traits and were maintained through maturity with few interchanges in ranking. The order of F1 cows for weight was as follows: Charolais (506 to 635 kg for different ages), Shorthorn and Salers, reciprocal Hereford-Angus (HA) with 1980s sires, Nellore, HA with reference sires, Galloway, Piedmontese, and Longhorn (412 to 525 kg for different ages). Order for height was as follows: Nellore (136 to 140 cm), Charolais, Shorthorn, Salers, HA with 1980s sires, Piedmontese, Longhorn, Galloway and HA with reference sires (126 to 128 cm). Hereford and Angus cows with reference sires were generally lighter than those with 1980s sires. In general, breed differences for height followed those for weight except that F1 Nellore cows were tallest, which may in part be due to Bos taurus-Bos indicus heterosis for size. 相似文献

液相色谱-串联质谱法测定动物尿液中11种β-受体激动剂残留量的不确定度评估 总被引:1,自引:1,他引:0
采用液相色谱-串联质谱法测定动物尿液中11种β-受体激动剂残留量,对标准溶液、体积、质谱峰面积、浓缩过程及回收率等测定不确定度因素进行了分析,通过评定各不确定度分量及标准不确定度,得出11种β-受体激动剂的扩展不确定度在0.7 ~ 1.1 ng/mL范围内.由各因素对合成不确定度的贡献比分析可知,影响较大的因素为试验回收率及标准溶液浓度. 相似文献
