Enrichment should be assessed to ensure it is being beneficially utilized by the animal. Enrichment types may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Social enrichment, which involves direct or indirect (visual, olfactory, auditory) contact with conspecifics (other individuals of the same species) or humans.\u00a0<\/li>\n\n\n\n<li>Occupational enrichment, which encompasses both psychological enrichment (e.g., devices that provide animals with control or challenges) and enrichment that encourages exercise.<\/li>\n\n\n\n<li>Physical enrichment, which can involve altering the size or complexity of the animal\u2019s enclosure or adding accessories to the enclosure such as objects, substrate, or permanent structures (e.g., nest-boxes, perches, huts, etc). These items should be sanitizable and inspected regularly to ensure they are safe for use.\u00a0<\/li>\n\n\n\n<li>Sensory enrichment, which involves stimuli that are visual (e.g., television or video), auditory (music, vocalizations), or in other modalities (e.g., olfactory, tactile, taste).<\/li>\n\n\n\n<li>Nutritional enrichment involves either presenting varied or novel food types or changing the method of food delivery<\/li>\n<\/ul>\n\n\n\n<p>Animal use, environment, and species will largely dictate the environmental enrichment needs of animal populations.&nbsp; Environmental enrichment programs may vary significantly across facilities and therefore should be detailed out in specific facility SOPs or Guidelines or other forms of documentation.<\/p>\n\n\n\n<p>Per the Guide, \u201cenrichment programs should be reviewed by the IACUC, researchers, and veterinarian (UAV or designee) on a regular basis to ensure that they are beneficial to animal well-being and consistent with the goals of animal use.\u201d&nbsp; Facility-level programs will be reviewed to ensure alignment with this standard during semi-annual inspections, and the overall program will be reviewed by the IACUC during the semi-annual program review.<\/p>\n\n\n\n<p>All NC State-owned animals must be enrolled in an environmental enrichment program unless a specific exception is described in the applicable IACUC Application for Vertebrate Animal Use and approved by the IACUC.&nbsp; Individual animal exemptions may be approved by the University Attending Veterinarian or designee for medical reasons.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.aphis.usda.gov\/animal_welfare\/downloads\/AC_BlueBook_AWA_508_comp_version.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Animal Welfare Act and Animal Welfare Regulations<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.asas.org\/docs\/default-source\/default-document-library\/agguide_4th.pdf?sfvrsn=56b44ed1_2\" target=\"_blank\" rel=\"noreferrer noopener\">The Guide for the Care and Use of Agricultural Animals in Research and Teaching<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/grants.nih.gov\/grants\/olaw\/guide-for-the-care-and-use-of-laboratory-animals.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">The Guide for the Care and Use of Laboratory Animals<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Standard The Guide states that \u201cthe primary aim of environmental enrichment is to enhance animal well being by providing animals with sensory and motor stimulation, through structures and resources that&hellip;<\/p>\n","protected":false},"author":1204,"featured_media":0,"parent":1180,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"source":"","ncst_custom_author":"","ncst_show_custom_author":false,"ncst_dynamicHeaderBlockName":"ncst\/default-header","ncst_dynamicHeaderData":"{\"pageIntro\":\"This standard defines\/describes environmental enrichment requirements for university-owned animals.
