汕头地区白壳蛋鸡与褐壳蛋鸡综合效益的比较

1农业技术学院毕业论文汕头地区白壳蛋鸡与褐壳蛋鸡综合效益的比较姓名院（系）生命科学学院专业班级动物科学041班学号指导教师职称教授论文答辩日期2008年5月日农业技术学院教务处制2摘要通过对汕头地区白壳蛋鸡和褐壳蛋鸡生产性能、白壳鸡蛋和褐壳鸡蛋物理性质、白壳鸡蛋和褐壳鸡蛋售出率的比较等，综合分析研究适合汕头地区的蛋鸡品种及其经济效益。结果表明白壳蛋鸡与褐壳蛋鸡相比，白壳蛋鸡料蛋比低，适合汕头地区规模化生产；市场上消费者对两种鸡蛋的消费取向不同，消费者多偏向于购买白壳鸡蛋。在汕头地区，蛋鸡场应该以白壳蛋鸡为主要蛋鸡品种，结合褐壳蛋鸡作为市场补充和调节。关键词汕头地区蛋鸡品种经济效益3目录1前言42材料与方法521饲料报酬的研究5211材料5212方法522蛋品测定材料和用具5221蛋品试验材料5222试验用具5223试验方法523销售量及销售价格统计调查6231材料6232方法63结果与分析631两种蛋鸡的饲料报酬对比分析632蛋品测定结果对比分析733销售量及销售价格统计调查分析84讨论941生产性能的不同对蛋鸡品种选择的影响942蛋品物理性质不同对蛋鸡品种选择的影响943市场销售情况对蛋鸡品种选择的影响1044G16892G5922G6373选适合汕头地区的蛋鸡品种105结论10G2454G13783G7003G1049810G14533G7003G6700要12G14280G1688613G4410生G6227G16846G108214G1904G1006G6228G7427G4410G19510G8617G1006论G7003G11G16786计G12G6116G13501G16792定表1541前言G6466G13864合G3281G12930G1904G13464G13467G708G41G82G82G71G68G81G71G36G74G85G76G70G88G79G87G88G85G72G50G85G74G68G81G76G93G68G87G76G82G81G82G73G87G75G72G56G81G76G87G72G71G49G68G87G76G82G81G86，G41G36G50G709统计G17176料，G6117G3281鸡蛋产量G11861990G5192的656G987G2556G3698G2164G20522007G5192的2730G987G2556，鸡蛋产量G1940G36982074G987G2556A1A0A2。G11458前G6117G3281鸡蛋产量的G5192G3698G19283G17907G5242和G5647产量G18129G1313G4633G1002G11040G20330G1313A1A3A2。G13792鸡蛋G2559G7389G1028G4512的G1260质蛋白，其G1025蛋G8700G18252G2559量G10317G2047G1028G4512A1A5A2，G6164以鸡蛋G9157G2475G5203G3835G1166G8677G13688G1259的G8438G17826。G19555G11540G3281G3818G5353G17839的蛋鸡品种的G3698G2164，不同G20080G14406的鸡蛋，G3926白壳鸡蛋、褐壳鸡蛋、G12893壳鸡蛋和G13523壳鸡蛋G1075G17892G9188G3835量G8981G1849G3281G1881消费市场，G17837G1363G5483G5203G3835市G8677在鸡蛋的选购上G7389G7368多的选择G12366G19400。在上G1002G1343880G5192G1207G1427990G5192G1207G1025G7411，G5203G1008蛋鸡G1871殖G1006曾经一G5242G17839G1849最发达时G7411，G1871殖数量和产蛋量G1313G4633全G3281G20330列。但G2052了1996G5192后，G19555G11540G3281企改革，G3818省蛋鸡产G1006迅G17907发展，省G1881G3835部分G3281G7389蛋鸡场因种种原因无法适应市场经济G13792相继被淘汰。G2052了2000G5192，G5203G1008蛋鸡G1871殖G1006完全步向衰落，省G1881的鸡蛋市场八G6116以上靠G3818省输G1849。近来，G5203G1008的蛋鸡G1871殖G1006已开始复苏，部分G3835型G1871殖场已G17839行了升级改造，G9188G9188在市场上占G6466了一定份额。在粤G1008地区G708以汕头为例G709，蛋鸡G1871殖G1006发展势头良好，G11458前已G7389十几家G3835型G1871殖场，其蛋品生产量在当地的市场份额G1025已占三G6116，在当地的蛋品生产G1025已具G7389举足轻重的作用。因此，详细了解汕头地区鸡蛋销售的各种影响因素，G10317G2047是G5353起蛋品价格变动的原因，对于生产企G1006具G7389一定的指导意义。当然，鸡蛋的社会需求和消费量的变化,直接关系G2052市场供求的平衡，是影响鸡蛋价格变动的主要因素A1A6A2，但是，蛋鸡品种以及G2475此影响的蛋品G14406泽、蛋品品种等G1075会影响G2052市场销售量和销售价格，同样会影响生产企G1006的蛋鸡品种选择、蛋品销售等。汕头地区鸡蛋消费市场以白壳鸡蛋和褐壳鸡蛋两种鸡蛋为主，主要鸡种以G5353G17839的海兰W36蛋鸡和海兰褐蛋鸡为主。消费者在选择鸡蛋的时候，往往表现出不同的购买倾向，G7389些G1166倾向于购买褐壳蛋，G13792另一些G1166则倾向于购买白壳蛋。无论消费者是否了解褐壳蛋与白壳蛋在营G1871价值上的差异，其消费倾向对生产者的影响是巨G3835的。G20330先，消费者的购买倾向会影响蛋品的销售量，并G17839G13792影响生产者的生产效益。因此，蛋鸡G1871殖场G1075G7389关于不同蛋鸡品种生产性能G7389差异，但在经济效益方面是否G1075存在差异，G11458前能够看G2052的G7003G10498还甚少。为此，针对汕头地区的蛋鸡生产和鸡蛋消费市场G17839行了调查和分析，以G7411为蛋品生产提供品种选择的依G6466。52材料与方法21饲料报酬的研究211材料正G3835康地G708汕头G709G7389限公司兴G19546蛋鸡场G70810G987G2494蛋鸡G7643G1946化G1871殖场G7092007G51929G7388G142792008G51922G7388的海兰W36蛋鸡和海兰褐蛋鸡的生产G16772G5417。212方法G1186蛋鸡场G18336G19555G7438G6289选海兰W36蛋鸡G14305G708G717G716G716G716G716G2494鸡G709一G1022和海兰褐蛋鸡G14305G708G717G716G716G716G716G2494鸡G709一G1022，调G19417G6922G19610其G718G716G716G723G5192G725G7388G14279G718G716G716G724G5192G718G7388的生产G16772G5417G708G2265G6336饲料消G13803量、产蛋量等G709，并G6466此分析了不同品种蛋鸡的料蛋比。22蛋品物理性状测定221蛋品试验材料G7044G21104白壳鸡蛋100G7534、G7044G21104褐壳鸡蛋100G7534；222试验用具G3837平、平G11411、G9228G7643G2357G4622、G19230G4388、G19097G12520、G16772G5417G7424等。223试验方法G7424试验G18331用G2345因G4388试验G16786计。G4570鸡蛋G6365G10043蛋壳G20080G14406不同分G6116两G13464，G2375白壳鸡蛋G13464和褐壳鸡蛋G13464，G8611G13464各100G7534。通过对其部分物理性质G17839行G16278G4531、G7828测G13792G5483出的结果G17839行对比分析A1A7A2。1G709鸡蛋G3818G16278G5430G10378G17892G1022G6355出G5465G7828蛋，G1192细G16278G4531测定其G5430G5589、G3835G4579、G14406泽等，然后G2045用G6175指G6732蛋的表面和G6486重，最后G2969G7828蛋壳表面G7389无异G5132G8680G2631。G4570G16278G4531G6164G5483G16772G5417在G16772G5417G7424上。2G709鸡蛋重量G18331用G12228重法，选取G5465G7828蛋G708白壳和褐壳各100G7534G709，用G5875量为001G74的G3837平，G12228量G8611G7534鸡蛋的重量。3G709蛋壳G2414G5242用G9228G7643G2357G4622测定。选取G8611G7534G5465G7828蛋G708白壳和褐壳各100G7534G709蛋壳的G1025G19400部G1313，G19512G2447壳G1881G14192后测出的G2414G5242，3G8437重复取其平G3355值。4G709G7389G15892G7013的鸡蛋数G11458、G7389G13917G7013的鸡蛋数G11458的统计G6183开G6164G7389G5465G7828蛋G708白壳和褐壳各100G7534G709，分G2047G16278G4531G8611G1022G6183开后的鸡蛋G1025的蛋G21656，看6其蛋G21656上是否G7389G15892G3371G6122G13917G3371，G14521G7389的则G4570其G16772G5417G991来，最后分G2047统计其G15892G7013率和G13917G7013率。23销售量及销售价格统计调查231材料G19417正G3835康地G708G9560海G709G7389限公司2007G51929G7388G142792008G51922G7388G18616G1022G7388的白壳蛋与褐壳蛋的销售量及销售额的统计数G6466。232方法G1186公司调G19417G6922G196102007G51929G7388G142792008G51922G7388的鸡蛋销售G16772G5417，G2265G6336白壳鸡蛋出场蛋G5647量、销售G5647量、销售G5647额；褐壳鸡蛋出场蛋G5647量、销售G5647量、销售G5647额。并G6466此分析不同品种鸡蛋的市场售出率。3结果与分析31两种蛋鸡的饲料报酬对比分析A4A8A9A10A11A12A13A14A15A16A17A18A4A19A20A21A22A23A24A25A26A27A28A19A20A23A24A29A19A20A30A31A32A33A34A35A36A37A38A39A40A19A36A37A38A39A33A19A41A32A33A34A35A36A37A38A39A40A19A36A37A38A39A33A19A41A33A19A41A42A43A44A45A45A46A47A45A48A44A49A50A51A27A52A49A50A51A52A52A45A45A50A52A49A51A47A48A49A45A45A53A51A27A52A27A46A27A45A51A27A51A50A48A49A28A50A51A49A44A47A51A50A45A51A53A51A45A47A51A46A45A51A44A45A45A46A4
