做大做强:心态、机遇、包容、能力、合作

个体户——小企业——大企业——超大企业，这是一连串做大的过程，真正的企业家都不会满足现状，他们总是要求发展，发展，再发展。因为经验告诉他们，如果一停下来，正如逆水行舟，他们就会被市场的大潮冲向岸边，撞得粉粹。只有求发展，才能求生存，这是市场规律，守是守不住的。同时，只有发展了，企业家才肩负     

螺、蚌、鱼、龟混养技术

利用水产生物链，科学混养龟、鱼、螺、蚌，可综合利用池水，改善水质，节省饲料，达到龟、鱼养殖周期长短互补的目的，其技术要点如下：１建池池子环境要求安静，阳光充足，可利用村间自然坑塘或庭院改建。池底面呈坡形，水浅的一面与池围墙之间留有１m宽的滩池（铺沙，供乌龟产卵栖息用）水深由０．０１m渐深至１．５m左右，使螺、蚌、龟、鱼各有自己的活动水域，池子可建成东西方向长方形，以便冬节搭塑料大棚保温。池围墙高出水面０．５m左右，池塘的进、排水口要安装拦鱼铁网。龟投料点为设在池边浅水处或岸边，鱼投料台设在深水处水面…

近期禽蛋、饲料、苗鸡、活鸡、父母代价格

自从2006年年底，我国国内CPI出现了抬头的态势。其中粮食消费价格增幅一直高于CPI，其对农产品价格也起到了一定的支撑作用，由于粮食作物需求一直逐年递增，为稳定CPI形成明显压力。     

全球家禽生产、屠宰、贸易、消费数据库

据联合国粮农组织最新估计，2005。年世界禽肉总产量为8110万吨，其中，鸡肉占86％，火鸡肉占6．5％，鸭肉占4．5％，鹅肉占3％（见表2）。受高致病性禽流感（HPAI）影响，禽肉生产和需求力度下降。2006年全球禽肉总产量比2005年少1％以上。

近期禽蛋、饲料、苗鸡、活鸡、父母代鸡价格

自国庆节至今，本地鸡蛋的价格呈“U”字型变化，国庆期间，本地商品鸡蛋的收购价为6．60元／千克，至10月中旬后，跌至6．00元／千克，后又下浮至5．80元／千克。而11月中旬又逐步回升到6．30～6．36元／千克，且目前仍有上升的趋势，究竟是何原因导致前期鸡蛋价格的波动，而后期的生产与市场又将会怎样呢？为此，笔者对从事蛋鸡生产经营及其炕孵企业的业主进行了全方位的调查了解，现将调查了解的情况浅析如下。

Supplementation of broodmares with copper, zinc, iron, manganese, cobalt, iodine, and selenium

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.     

Comparisons of Angus, Charolais, Galloway, Hereford, Longhorn, Nellore, Piedmontese, Salers, and Shorthorn breeds for weight, weight adjusted for condition score, height, and condition score of cows

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.     

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

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.     

Granulocyte isolation from whole blood of goat, sheep, cattle, horse, dog, pig, and man

A simple two step procedure for the isolation of caprine, ovine, bovine, equine, canine, porcine and human peripheral blood granulocytes is described. After enrichment of granulocytes by centrifugation, contaminating erythrocytes are lysed hypotonically. Recovery, purity, and viability of the granulocyte suspensions are determined. FACScan analysis of the cell suspensions measuring cellular size by forward and sideward light scatter is compared with the corresponding analysis of whole blood leukocytes. Constituencies of the isolated cell suspensions and loss of granulocyte subpopulations through isolation procedure is discussed with regard to granulocyte function assays.
