These dysfunctions translate into poorer average daily gain (ADG), greater batch heterogeneity, increased lesions, higher susceptibility to disease, and consequently, more intensive use of antimicrobials.<\/p>\n<blockquote>\n<p class=\"MsoNormal\">A multifactorial approach to animal welfare requires interventions that directly impact behavior, environment, and physiology on pig farms.<\/p>\n<\/blockquote>\n<p class=\"MsoNormal\">In this context, environmental enrichment through manipulable materials or toys represents an effective, evidence-based strategy to improve animal comfort, prevent abnormal behaviors such as tail biting, and stabilize social hierarchy in housed groups.<\/p>\n<p class=\"MsoNormal\">Research studies and field trials support that appropriate oral and sensory stimulation reduces stress expression and improves key productive markers across all production phases.<\/p>\n<p class=\"MsoNormal\">The current regulatory framework, particularly Royal Decree 159\/2023 governing housing and management conditions, as well as IAWS and WELFAIR\u00ae certification protocols, strengthens the need to implement effective, durable, safe, and stage-appropriate enrichment systems.<\/p>\n<p class=\"MsoNormal\">In this regard, companies such as <strong>Porcsavi<\/strong>, specialized in animal welfare and biosecurity solutions for the swine sector, have developed in collaboration with <strong>AMBiotec<\/strong> a range of enriched toys designed not only to promote natural behaviors but also to provide physiological functionality. By incorporating natural ingredients, plant extracts, and high-quality bioactive compounds, these devices act as <em>environmental nutraceuticals<\/em>, delivering beneficial effects on digestive health, gut microbiota, and animal immunocompetence.<\/p>\n<p class=\"MsoNormal\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-7598 aligncenter\" src=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-2-300x246.png\" alt=\"\" width=\"432\" height=\"354\" srcset=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-2-300x246.png 300w, https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-2.png 451w\" sizes=\"(max-width: 432px) 100vw, 432px\" \/><\/p>\n<h2 class=\"MsoNormal\"><b>Foundations of Environmental Enrichment in Pigs<\/b><\/h2>\n<h3 class=\"MsoNormal\"><b>Pig Ethology and Exploratory Needs<\/b><\/h3>\n<p class=\"MsoNormal\">The domestic pig (Sus scrofa domesticus), as a highly exploratory and intelligent species, innately exhibits a need to interact with its environment through behaviors such as rooting, chewing, sniffing, and manipulating objects. These activities not only satisfy behavioral needs but also promote neuroplasticity, emotional stability, and social cohesion within the group. The absence of adequate stimuli leads to behavioral deviations characterized by stereotypies, aggression, tail biting, and other signs of discomfort that negatively impact productivity.<\/p>\n<h3 class=\"MsoNormal\"><b>Functional Requirements of Enrichment Materials<\/b><\/h3>\n<p class=\"MsoNormal\">To be considered effective, enrichment materials must meet a series of properties established by technical bodies such as EFSA, as well as Spanish sectoral guidelines.<\/p>\n<p class=\"MsoNormal\">These requirements include:<\/p>\n<p>\u2022 <strong>Manipulability: the ability to be moved, pushed, chewed, or deformed by the animal.<\/strong><br \/><strong>\u2022 Investigability: olfactory, gustatory, or tactile stimulation that sustains animal interest.<\/strong><br \/><strong>\u2022 Safe composition: no risk of toxicity, hazardous fragmentation, or obstructive ingestion.<\/strong><br \/><strong>\u2022 Adequate durability: mechanical resistance adapted to the activity level of the animal, without premature loss of stimulation.<\/strong><br \/><strong>\u2022 Innovation and rotation: design that allows sensory novelty and prevents habituation.<\/strong><\/p>\n<p>Materials may be edible (pressed blocks, vegetable ropes), semi-hard (soft woods), or mobile (balls, chains), and their combination optimizes positive effects on behavior and performance.<\/p>\n<p class=\"MsoNormal\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-7596 aligncenter\" src=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-1-300x200.png\" alt=\"\" width=\"468\" height=\"312\" srcset=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-1-300x200.png 300w, https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-1.png 406w\" sizes=\"(max-width: 468px) 100vw, 468px\" \/><\/p>\n<h2 class=\"MsoNormal\"><b>Application Across Production Phases<\/b><\/h2>\n<h3 class=\"MsoNormal\"><b>Post-weaning piglets<\/b><\/h3>\n<p class=\"MsoNormal\">Weaning is one of the most vulnerable stages of the cycle due to the convergence of stressors: maternal separation, dietary change, social reorganization, and exposure to new pathogens. The use of enriched toys at this stage has been shown to:<\/p>\n<p><strong>\u2022 Reduce vocalizations and signs of anxiety.<\/strong><br \/><strong>\u2022 Increase early intake of solid feed.<\/strong><br \/><strong>\u2022 Improve average daily gain in the first weeks.<\/strong><br \/><strong>\u2022 Lower incidence of post-weaning diarrhea.<\/strong><\/p>\n<p>A relevant advancement in this context is the incorporation, in toys developed by Porcsavi in collaboration with AMBiotec, of a phytobiotic core to enhance animal health. This core is composed of essential oils and plant-derived active compounds selected for their antioxidant, anti-inflammatory, and digestive effects, which contribute to maintaining a balanced gut microbiota and a functional mucosal barrier. Thus, the toy acts as a \u201cbehavioral and nutraceutical vector\u201d, simultaneously supporting natural behavior and gastrointestinal health.<br \/>With group size-adapted presentations, this solution represents a comprehensive support against the challenges of weaning, aligned with antimicrobial reduction strategies.<\/p>\n<h3 class=\"MsoNormal\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-7602 aligncenter\" src=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-4-300x178.png\" alt=\"\" width=\"524\" height=\"311\" srcset=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-4-300x178.png 300w, https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-4.png 434w\" sizes=\"(max-width: 524px) 100vw, 524px\" \/><\/h3>\n<h3 class=\"MsoNormal\"><b>Fattening Phase<\/b><\/h3>\n<p class=\"MsoNormal\">During fattening, groups present a higher risk of tail biting, especially when tails are not docked. Environmental enrichment at this stage has proven effects:<\/p>\n<p><strong>\u2022 Reduced aggression and bite-related lesions on farms.<\/strong><br \/><strong>\u2022 Fewer treatments for secondary infections.<\/strong><br \/><strong>\u2022 Improved batch homogeneity.<\/strong><br \/><strong>\u2022 Increased feed efficiency.<\/strong><\/p>\n<p>Porcsavi\u2019s toys for this phase are formulated with natural compounds that induce relaxation and stimulate sustained oral manipulation, improving animal health and maintaining interest for 6\u20138 weeks. In addition, their design prevents premature deterioration, allowing continuous use without frequent replacements, optimizing the cost\/benefit ratio.<\/p>\n<h3 class=\"MsoNormal\"><b>Gestation and Pre-farrowing<\/b><\/h3>\n<p class=\"MsoNormal\">Group housing of pregnant sows requires special welfare attention, as episodes of aggression negatively affect embryo implantation and increase litter variability. Environmental enrichment during gestation helps improve animal health through:<\/p>\n<p><strong>\u2022 Reduction of hierarchical conflicts.<\/strong><br \/><strong>\u2022 Improved emotional stability.<\/strong><br \/><strong>\u2022 Fewer skin lesions and lameness.<\/strong><br \/><strong>\u2022 Better reproductive parameters (successful farrowings, liveborn piglets).<\/strong><\/p>\n<p>The enriched products developed for this phase integrate ingredients with relaxing effects and sensory attractants that capture sow attention and redirect exploratory behavior away from the flanks of pen mates.<\/p>\n<p class=\"MsoNormal\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-7604 aligncenter\" src=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-5-300x196.png\" alt=\"\" width=\"546\" height=\"357\" srcset=\"https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-5-300x196.png 300w, https:\/\/www.ambiotecsolutions.com\/wp-content\/uploads\/2025\/09\/Post-Imagen-5.png 439w\" sizes=\"(max-width: 546px) 100vw, 546px\" \/><\/p>\n<h3 class=\"MsoNormal\"><b>Lactation and Postpartum<\/b><\/h3>\n<p class=\"MsoNormal\">The peripartum period is critical for maternal and neonatal welfare.
