Abstract

Description
本发明一般涉及促进猪生长的方法,特别涉及采用猪生长激素与高营养价值的赖氨酸结合,以协同促进猪的生长,增加猪体重和提高猪饲料利用率的方法。
生长激素(ST),本领域中有时称之为GH,通常是在动物的整个生命期内由垂体产生的,当然成年期前的产量更高。ST可促进骨骼生长,氮的保持,蛋白质合成,及影响葡萄糖和脂类代谢。因此,ST被公认为是一种通用的合成代谢剂。
虽然ST作用的机理还未被充分认识,但业已证实,施用与试验对象同种的外源ST,能显著加快动物的生长速度,增加体重和提高产肉量;猪生长激素能改善食用肉的化学组成。见E.J.Truman,“Some Effects of Pituitary Anterior Growth Hormone On Swine”,Thesis;Purdue University(April 1953)。
ST可从离体垂体组织分离得到。例见C.H.Li,J.Biol.Chem.211,55(1954)。ST也可通过遗传工程方法由含专门产生ST的重组体DNA的微生物中获得。例见:P.H.Seeburg,et al.,Nature,276,795-798(1978);P.H.Seeburg,et al.,Nature,270,486-494(1978);J.A.Martial,Science,205,602-607(1979)。
猪生长激素(pST)(本领域中也称为pGH)是一种在垂体前叶中合成并由其分泌的多肽。pST的制备在本领域中是众所周知的。例如,美国专利第3,201,382号公开了一种从离体垂体组织分离动物生长激素(如pST)的方法。欧洲专利申请第83305717.7号(1983年9月26日提交,公开号为104,920)揭示了DNA顺序、重组体DNA分子和适合于产生pST的转移宿主,欧洲专利申请第83306730.9号(1983年4月11日提交,公开号为111,389)也介绍了DNA顺序和产生pST的转移宿主。
赖氨酸是动物正常生长发育所必需的基本氨基酸。动物饲料中含有不等量的赖氨酸。然而,特别在动物饲养中,必须将补充的赖氨酸加到动物饲料中,以保证正常的营养。
此外,本领域中还采用高营养价值的赖氨酸,以促进生长,增加体重和提高饲料利用率。授予Olson的美国专利3,868,467号公开了一种包含高含量赖氨酸的玉米的饲料组合物,由此可促进猪仔的快速生长。该组合物还可进一步包含作为独立添加剂加入的赖氨酸,其中该赖氨酸占组合物总重量可高至0.25%。授予Hauck等人的美国专利第4,172,148号公开了通过加入赖氨酸的三氯乙酯来促进反动物生长和提高饲料利用率的方法。然而,已观察到,采用高含量赖氨酸的饲料组成,可使体重增加得更快,提高饲料利用率,参见:Baker,et al.,Lysine Requirement of Growing Pigs at Two Levels of Dietary Protein,40J.Anim.Sci.851(1975);Brown,et al.,Lysine Requirement of the Finishing Pig for Maximun Rate of Gain and Efficiency.37 J.Anim.Sci.708(1973);Kornegay,et al.,Supplementation of Lysine,Ammonium Polyphosphate and Urea in Diets for Growing-Finishing Pigs,34 J.Anim.Sci.55(1972),Williams,et al.,The Lysine Requirement of the Growing Boar Versus Barrow,58 J.Anim.Sci.657(1984)。
生长激素和高含量赖氨酸饲料各自均能促进猪的生长。然而,必需采用结合使用已知生长促进剂的方法,以协同促进生长;协同结合后可减少所需单个成分的剂量,因而降低了促进生长所需原料的成本。
因此,本发明的目的之一在于提供一种促进猪的生长,增加猪的体重,提高猪饲料利用率的方法。
本发明的目的之二在于提供一种协同促进猪的生长,增加猪的体重,提高猪饲料利用率的方法。
本发明的目的之三在于提供一种方法,用以降低促进猪生长、增加其体重和提高猪饲料利用率所需原料的成本。
上述目的和其它目的的实现可结合施用猪生长激素(pST)和高含量赖氨酸饲料,协同促进猪生长,增加其体重和提高猪饲料利用率。最好通过下述方式施用化合物:(1)采用诸如注射或植入等常规方法,将猪生长激素(pST)施用于猪;(2)将含有足量赖氨酸、并与pST混合的饲料喂猪,以协同促进生长,增加体重和提高饲料利用率。
在优选实施例中,以大约1-20mg/猪/天、最好是3-6mg/猪/天的剂量将pST施用于猪;以大约0.9~1.6%(重量)、最好是大约1.1~1.4%饲料赖氨酸的量,将赖氨酸提供给猪,以协同促进猪的生长,增加其体重和提高猪饲料利用率。
通过以下对本发明的详细描述,本发明的其它目的、优点和新特征将是显而易见的。
图1显示,与采用pST和低含量赖氨酸饲料对比,由于结合使用pST和高含量饲料赖氨酸饲料,增加体重和提高饲料利用率的百分比。
本文所用“高含量饲料赖氨酸”一词意指含大约0.9%(重量)或更高含量赖氨酸的饲料。
根据本发明,结合施用猪生长激素(pST)和高含量饲料赖氨酸,可协同促进猪生长,增加其体重,以及提高猪饲料利用率。
pST可取自任何适宜的来源。生产、分离和提纯天然和重组体pST的方法在本领域内是众所周知的。本发明所采用的pST包括具有pST活性的所有蛋白质,包括具有缺少、置换或交替的氨基酸顺序的天然蛋白质、重组体蛋白质和突变蛋白质,及其具有生物活性的片段。
虽然pST的剂量因具体猪的年令、大小和性状不同而变化,但一般以大约1-20mg/猪/天、最好以大约3-6mg/猪/天的剂量施用于猪。
可采用任何适宜的方式将本发明的pST提供给猪,包括注射、采用植入物等方式施用。以注射和植入的方法为佳,因为可精确地控制施用时的计时和剂量水平。本发明的pST最好非经肠道施用。本文中所指的非经肠道施用方法包括静脉、皮下、肌肉或腹膜内注射,或皮下植入。
注射施用时,可将本发明的pST制成可注射的配制剂施用于猪。所述配制剂中含任何生物上可相容的和与pST可相容的载体,例如各种赋形剂、佐剂、添加剂和稀释剂。注射时,以足以提供大约1-20mg/猪的量,将本发明的pST加到载体中。较为理想的是,以足以提供3-6mg/猪的量,将本发明的pST加到含大约0.4-0.5M盐酸精氨酸的缓冲液中。
含水载体,例如不带非挥发性热原质的水、无菌水和抑菌水,也适宜于制成注射用pST溶液。除上述形式的水外,还可采用若干其它含水载体,这些载体包括能被消毒的等渗注射组合物,例如氯化钠溶液、林格氏溶液、右旋糖溶液、右旋糖和氯化钠溶液,以及乳酸林格氏液。加入水混溶性溶剂,例如甲醇、乙醇或聚丙二醇,通常能提高pST在这些载体中的溶解度和稳定性。
也可将非含水载体,例如棉籽油、芝麻油或花生油以及诸如肉豆蔻酸异丙酯的酯用作pST组合物的溶剂系统。
此外,可加入能够增加组合物稳定性、无菌性和等渗性的各种添加剂,包括抗菌防腐剂、抗氧化剂、螯合剂和缓冲剂。然而,根据本发明,所用的载体、稀释剂或添加剂应是生物上可相容的和与pST可相容的。较理想的是,施用时将pST溶解在含大约0.4-0.5M盐酸精氨酸的缓冲液中。
可将本发明的pST植于猪皮下,以缓慢释放的皮下植入物的形式施用。该植入物可以是在植入猪皮下后缓慢溶解的小丸,或是生物上可相容的以及与猪可相容的专业上公知的微型缓释制剂(delivery module)的形式。设计这类剂型的目的是使活性成分在几天至几星期的期间内缓慢释放。设计植入物的目的是使活性成分以大约1-20mg/猪/天、最好是大约3-6mg/猪/天的剂量释放。
赖氨酸是一种基本氨基酸,赖氨酸是促使猪生长发育的饲料所必需的。赖氨酸存在于天然猪饲料如玉米和大豆中,但其含量通常不足以满足猪生长所需的营养要求。国家研究委员会最近(1988)规定,50-100公斤重猪的饲料赖氨酸需要量应占0.6%。若饲料中的含量低于这一要求,则应补充加入赖氨酸。补充的赖氨酸可取自任何适宜的来源。饲料级赖氨酸可从Biokyowa Inc.(1400 Elbridge Payne,Chesterfield,MO63017)购得。某些饲料中可能天然含有一定量的与pST结合的赖氨酸,因而能协同促进猪生长,增加其体重,以及提高猪饲料利用率。然而,最常用的还是应将补充赖氨酸加到猪饲料中,以便与pST结合,提供协同促进生长所需的高营养赖氨酸。
虽然赖氨酸的剂量因具体猪的年令、大小和性状而变化,但赖氨酸的施用剂量一般大约为0.9%~1.6%饲料赖氨酸,优选剂量为1.1%~1.4%。在优选实施例中,以足以提供所需剂量的量,将赖氨酸与猪饲料混合,一般制成一种含大约0.9%~1.6%、优选1.1%~1.4%赖氨酸的饲料组合物。
可按任何可接受的方式,最好是口服方式,将本发明的赖氨酸提供给猪。口服包括以片剂、混悬液、溶液、乳剂、胶囊剂、粉剂、糖锭剂、饲料组合物等形式施用赖氨酸。例如,可将赖氨酸与普通饲料组合物混合。在优选实施例中,将赖氨酸提供给猪的方式是:将含有赖氨酸的饲料组合物提供给猪,其中赖氨酸以足够的量与pST结合,由此协同促进猪生长,增加其体重,以及提高猪饲料利用率。
若以饲料组合物的形式施用赖氨酸,则根据本发明,饲料组合物可含补充赖氨酸及常规营养平衡饲料,其中包括大量碳水化合物、脂肪、蛋白质、维生素和矿物质。饲料组合物中包含的某些普通营养物为谷物(如磨碎的谷粒和谷粒副产物),猪蛋白物质(如鱼粉和肉粉中的蛋白质),植物蛋白(如大豆油渣粉或花生油渣粉),维生素和含维生素物质(维生素A和D混合物、维素素B2添加剂和其它维生素B复合物成分),以及产生矿物质的骨粉和石灰石。供猪食用的一类传统饲料的成分包括玉米和大豆粉,以及与之结合的补充维生素、含维素生物质和矿物质(若需要的话)。本发明中可采用的一种公知饲料组合物的实例包括美国专利No.4,320,116中所述的成分(供猪、猪仔等食用的基本成分),本文将该专利文献作为参考文献。对专业人员而言,其它这类饲料组合物也是已知的。
本文中所定义的“结合”施用pST和赖氨酸包括多种方法,目的在于在同一时间内将pST和赖氨酸提供给猪,使猪获得所需协同剂量的化合物。具体实例包括:(1)植入能够在长时间内释放pST的pST释放装置,以及将赖氨酸每天同猪饲料一起喂饲给猪;或(2)定期注射pST,并将赖氨酸与猪的日食饲料混合一起喂饲给猪。
由于pST和赖氨酸可独立施用,因此本发明产品还可包装成小袋,包括单独包装或分装的容器,即含有(1)猪生长激素(pST)和(2)适宜于同pST结合形成饲料组合物的赖氨酸添加剂。所述小袋包含pST的形式应适合于供药给动物,即应呈注射配制剂或植入物的形式,并且小袋内应包含适宜于同常规饲料混合的赖氨酸,从而产生含“高含量饲料赖氨酸”的饲料组成。也可将赖氨酸添加剂直接提供给动物,不必将其与动物饲料混合。
小袋可含一种或多种呈植入物或注射配制剂的pST,以便以大约1-20mg/猪/天的剂量,定期地施用于动物。小袋还可含浓缩的赖氨酸添加剂,供与动物饲料混合,产生含本发明所需量赖氨酸的〔约0.9~1.6%(重量)饲料赖氨酸〕的饲料。
按本发明,pST和赖氨酸结合使用,可协同促进猪的生长,增加其体重,以及提高猪饲料利用率。
以上对发明作了全面描述,下面给出本发明的具体实施例,以说明其实际应用和优点。应该理解到,实施例用以说明而决不是限制说明书或所附权利要求书。
实施例1
根据健康和体重状况,选择试验用72头杂交种阉猪。将动物任意分配于各个圈内,于处理开始前使其适应环境约两周。在预实验期间,使所在的猪接受表1所示的饲料组合物。饲料和水可任意提供。
将阉猪分为八个处理组,每组9头按表2所示的量施用pST和赖氨酸。
从每批用于试验的饲料中采集试样,在实验结束时,将这些试样混合,分析粗蛋白、赖氨酸、钙和磷。
在0.427M盐酸精氨酸中制备pST的注射液。在无菌状态下,将盐酸精氨酸加到pST中,制成所需pST浓缩液。空白对照液仅含盐酸精氨酸溶液。各个剂量的总体积均为1ml。在颈背部肌内注射所述注射液,颈背两侧交替进行注射。用一种新型无菌注射器注射每一剂量浓缩液。全部注射时间为800至1000小时,每天注射。每天检查注射部位的状况,并记下实验数据。
在试验开始时,试验期间和第56天,定期对猪称重,测定饲料吸入量。将第56天测定的重量和饲料吸入数据用于测定体重日均增量、饲料日均吸收量和饲料日均利用率。试验采用2X4因子设计方法以pST剂量/频率和饲料赖氨酸为主效应。将猪圈位置作为区组因子,以初始体重作为生产动态数据的协变量。试验结果示于表3。通过方差分析分析所得数据(SAS,1985)。图1给出百分比提高程度表示的结果。
参见表3和图1,当将赖氨酸与pST结合施用时,体重增量和饲料利用率更高。在缺少pST的情况下,加入饲料赖氨酸,日均增量仅为1.2%;而以5mg pST/天、10mg pST/2天和15mg pST/3天的剂量施用时,日均增量分别提高12%、7%和2%。在缺少pST的情况下,加入饲料赖氨酸,饲料利用率提高5%,而以5mg/天、10mg/2天和15mg/3天的剂量结合使用pST处理,则饲料利用率分别提高17%、12%和8%。此外,体重增量和饲料利用率的提高不是简单的加法提高,而是协同提高。
显然,根据上述说明,可对本发明作出多种改进和改变。因此,可以理解到,本发明可在权利要求书的范围内实施,而并非局限于上述具体说明的内容。
