在武汉茶叶市场内举办的“2 0 0 2湖北迎春茶叶交易会”上 ,中国茶叶流通协会理事、湖北省茶叶学会副理事长张岳峰呼吁重整“楚茶文化” ,发展规模经营 ,以品牌带动市场。湖北是茶神神农氏、茶圣陆羽的故乡 ,恩施、宜昌、英山等地宜种茶树 ,湖北种茶面积居全国第三 (2 0 0万亩 ) ,目前有 30 0多种茶叶品牌 ,但在全国排上名的没有几个。张岳峰副理事长分析 ,当前湖北从事茶叶生产的多为贫困山区茶农 ,以茶谋生为主 ,几乎没有规模生产和销售意识 ,多生产中低档茶 ,湖北茶叶并非不出好茶 ,而是缺乏品牌带动。湖北茶叶市场均价仅为 14元 /ｋｇ ,… 相似文献

建德市 5个较大集镇自 1 998年开始实施定点屠宰以来 ,经过 5年左右的实践 ,已摸索出一条适合农村山区的屠宰运作模式。1 农村定点屠宰模式的建立建德市 ,常年上市生猪 1 5万头左右 ,分布在 2 30 0 km2 范围内饲养 ,养猪者千家万户。 2 0世纪 80年代后期生猪经营放开后 ,全市屠工户走乡串户上门收购生猪 ,就地屠宰销售 ,可谓是点多线长。为了确保群众吃上“放心肉”,建德市开始对上市生猪全面实行“定点屠宰”。但因当时仅由国有食品部门设立了少数几家生猪定点屠宰场 ,屠商必须串家挨户收购生猪 ,运送至定点屠宰点 ,进行统一屠宰和检疫 ,… 相似文献

遂川特产丰饶众多,但颇有名气且效益高的还得数狗牯脑茶。狗牯脑茶历经200多年的沧桑岁月,发展至今,面积、产量都有较大增长,实属不易;但作为1915年就获得巴拿马国际博览会金奖的优质农产品,在当今市场经济的大潮中,狗牯脑也只能算“肩挑手提”的“山货”,这又不得不说遗憾。全县现有茶园面积3 600 hm2,年产量仅为650 t,产值5 280万元。而作为龙头企业的狗牯脑茶厂每年收购销售茶叶也仅在2万kg之内,销售额在300万元左右。县内其它茶厂的销量更是极其有限,大多数茶厂销售的茶叶数量还不如单个茶叶销售户(店)。因此,必须花大力气做强狗牯脑,全… 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献

OBJECTIVE: To determine whether serum concentrations of biomarkers of skeletal metabolism can, in conjunction with radiographic evaluation, indicate severity of osteochondrosis in developing horses. ANIMALS: 43 Dutch Warmblood foals with varying severity of osteochondrosis. PROCEDURE: 24 foals were monitored for 5 months and 19 foals were monitored for 11 months. Monthly radiographs of femoropatellar-femorotibial and tibio-tarsal joints were graded for osteochondral abnormalities. Serial blood samples were assayed for 8 cartilage and bone biomarkers. At the end of the monitoring period, foals were examined for macroscopic osteochondrosis lesions. RESULTS: Temporal relationships were evident between certain serum biomarkers and osteochondrosis severity in foals during their first year. Biomarkers of collagen degradation (collagenase-generated neoepitopes of type-II collagen fragments, type-I and -II collagen fragments [COL2-3/4C(short)], and cross-linked telopeptide fragments of type-I collagen) and bone mineralization (osteocalcin) were positive indicators of osteochondrosis severity at 5 months of age. In foals with lesions at 11 months of age, osteochondrosis severity correlated negatively with COL2-3/4C(short) and osteocalcin and positively with C-propeptide of type-II procollagen (CPII), a collagen synthesis marker. Radiographic grading of osteochondrosis lesions significantly correlated with macroscopic osteochondrosis severity score at both ages and was strongest when combined with osteocalcin at 5 months and CPII at 11 months. CONCLUSIONS AND CLINICAL RELEVANCE: The ability of serum biomarkers to indicate osteochondrosis severity appears to depend on stage of disease and is strengthened with radiography. In older foals with more permanent lesions, osteochondrosis severity is significantly related to biomarker concentrations of decreased bone formation and increased cartilage synthesis. 相似文献
