Abstract Thepurposeofthispaperistopresentareview of the current scientific approach to the concept and definition of animal welfare. The need for interaction betweendifferentdisciplinesisemphasized,aswellasthe need to assess well being scientifically using validated indicators. The role of applied ethics in animal welfare scienceisemphasized.Thepaperprovidesabriefoverview ofthehistoricalstepsinthedevelopmentoftheconceptand presents a scientific approach, briefly explaining their theoreticalfoundations.Thepossibilityofdefiningwelfare onascientificbasisisexpressed,finding themainproblems intheview ofthescientific,culturalandsocialbackground. Another aspect considered is the relationship between welfare and morality, attesting to the meaning of such interactionanditspossibledevelopment
Theterm'animalwelfare'isoftenusedinboththegeneral and scientific communities to refer to a concept. In this context, positive animal welfare can be replaced with the word'well being'.TheAnimalWelfareLaboratoryservesas the cornerstone for foundation for the use of animals in veterinary medicine and research. ‘Animal welfare’ also refers to measurable conditions in an animal that may be relatedtotheadequacyoftheanimal’sabilitytocopewith itsenvironment.Animalwelfareisabranchofsciencethat looksatthesemeasurableconditionsinalmostallareasof our interaction with animals agriculture, recreation, companionship, research and more. This chapter will highlightthesignificantemphasisonanimalwelfareinthe field of laboratory zoology and medicine, beginning with someofthehistory,philosophy,ethicsandeventsthathave shapedtheimpactofanimalwelfareontheuseofanimalsin research.Lawsandregulationswillbementionedbrieflyas they are covered elsewhere in this book; However, guidelines and principles, such as 3R, will be covered in more detail.

Animal welfare is a multifaceted issue with important scientific,ethical,economicandpoliticaldimensions(Lund
et al., 2006). This science requires an inter disciplinary approach, which brings together rediscoverers of various disciplineswithinthebiologicalsciences,suchasphysiology, veterinary science, ethology and comparative psychology. Furthermore,although the firstphases werebasedonthe naturalsciences,lateritappearednecessarytouseabroader multidisciplinary approach to scientific animal welfare questions. Indeed this approach, primarily combining the study of ethology, physiology, psychology, and human animalinteractions,canprovidemethodologicaladvantages whileimprovingunderstandingofknowledgeaboutanimal welfareissues..Asfarasethicsisconcerned,thisdiscipline hasanimportantroleinthedevelopmentofanimalwelfare science(Milmanetal.,2004)andappliedresearch.Applied ethicists tend to use a "whole animal" approach, which involves the study of the causality and development of behavioralsystems,relatedtoanunderstandingofanimal stress,linkingbehaviortoitsphysiological spatialbasesand processes. (Broom & John Sun, 1993; Moberg & Mench, 2000). The practical application of research results on appliedethologycancontributetoimprovingthedesignof housingandequipmentandmanagementpractices(Grandin, 1993),allowinganimalstoexpresstheirbehaviorandcope withtheenvironment.
Animal welfare as a 'formal discipline' began with the publicationoftheBram BellReportontheWelfareofFarm Animals, issued by the British Government in 1965 (Brambell Report, 1965). The adoption of a traditional scientificapproach,withexperimentsfocusingontheeffects ofsinglefactorsundercontrolledconditions(Sando et al., 2003), established the new discipline as a science, or "a young science". permitted to. (Milman et al., 2004). There has been an enormous amount of research about animal welfareproblems.

In fact the American School of Behaviorismatthebeginningdidnotaccept"allsubjective termssuchassensation,perception,image,desire,andeven thought and emotion" in scientific terminology (Watson, 1928; Skinner, 1938). Initially ethicists also generally restrictedtheirviewstoobservablebehavior,althoughusing terms such as 'hungry,' 'pain,' 'fear' and 'disappointment' (Duncan,2006).Inaddition,positionssuchasthefollowing were adopted by many scientists (Tinbergen, 1951): "Because subjective phenomena cannot be objectively observed on animals, it is useless to claim or deny their existence."Animalsensibilityhasbecomeanimportantissue formeafterthepublicationofGriffon'sbook(Griffun,1976). Becauseofthedevelopmentofresearchandchangesininitial conditions,psychologyandethicsbegantocooperate.Thus, contrarytothebeliefthatwecanneverknowhowanimals feel, but only how they behave, some ethologists, such as Dawkins(1980,1993)andcognitivepsychologists,suchas Toots(1986),studiedIs.Theabilitytolearnfromothersfor perception, decision making, self awareness, or understanding animal minds.

Of course the perception of stimuli and the resultingresponsetothemaredeterminedbytheinteraction between genotype (species and ethnicity) and learning (experienceandinterpretationofthatexperience)(Webster, 1994). The possibility of deepening knowledge of animal minds also makes it possible to better understand the 'subjective experiences' of animals, both positive and negative. These latter may also include 'suffering', which includes "a wide range of unpleasant emotional states" (Duncan and Dawkins, 1983). Suffering occurs "when unpleasantsubjectivefeelingsareintenseorpersistforalong periodoftime,becauseananimalisunabletoperformtasks thatwouldnormallyunderthosecircumstancesposeariskto lifeandreproduction"(Dawkins,1990).Variousaspectsof theconceptofanimal welfareshouldalwaysbetakeninto accountinthestudyofanimalscience.Thismeansthatallthe biologicalcomponents,bothphysicalandpsychological,that agree in determining the level of well being, have to be studied and linked together.

Although "welfare can be assessed in a scientific manner without involving ethical considerations" (Fraser and Broom,1997),thewholeconceptofanimalwelfareandits evaluation can include values and judgments and morals. Decisions about how animals should be treated. Thus the scientificapproachtoanimalwelfarecanbecombinedwith anethicalapproachintheincreasingconvergenceofscience and philosophy, although this is not necessarily the case. Indeed ethicists began to look to empirical research to address issues of morality, while animal welfare science began to rediscover the importance of subjective experiences(Lundetal.,2006).Scientistswhostudyanimal welfareandphilosopherswhowriteaboutanimalethicsare basically two different cultures, though both work to understandandexplaintheproperrelationshipofhumans withanimalsofotherspecies(Fraser,1999).Philosophers "focusonlyontheindividuallevel,advocatingsingleethical principlesandseekingsolutionsthroughmoraltheorywith little recourse to empirical knowledge.
