A spectacular phenomenon, closely tied to the reproductive cycle of these majestic animals.<\/strong><\/p>\n<h2 class=\"wp-block-heading\"><strong>Annual Cycle<\/strong><\/h2>\n<p>While horns are made up of a bone core surrounded by keratin, the antlers of <strong>cervids<\/strong> are technically branched bones. In the males of several iconic species, these impressive structures shed each year and are replaced by new ones coated in a velvet-like layer. Their friction against trees subsequently helps remove this highly vascularized and innervated specialized tissue.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">These wasps threaten a symbiosis between ants and plants dating back more than 10 million years<\/span><\/section>\n<p>Antlers are considered the fastest-growing tissue in the animal kingdom, notably triggered by the increase in sunlight and in testosterone production during the months preceding the rut, which occurs in autumn.<\/p>\n<p>Their size is indicative of age, as well as the vigor and good physical and genetic condition of the animal. At the end of the mating season, punctuated by often-violent inter-male duels, testosterone levels in the blood drop significantly, which causes the antlers to fall off.<\/p>\n<p>Their sustained development involves a high energy expenditure (nutrients, minerals, and proteins). Thus, shedding them at the beginning of winter helps males to endure the harshest months of the year, when food is scarce.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">Everest aquatique: de minuscules poissons gravissent un cascade de 15 m\u00e8tres de haut<\/span><\/section>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"535\" src=\"https:\/\/www.farmersforum.ie\/trends\/wp-content\/uploads\/2026\/05\/1777814728_91_Why-Do-Deer-Shed-Their-Antlers.jpg\" alt=\"\" class=\"wp-image-659612\"  ><\/figure>\n<h2 class=\"wp-block-heading\"><strong>Croissance soutenue<\/strong><\/h2>\n<p>\u00c0 chaque repousse, ces structures se r\u00e9v\u00e8lent plus d\u00e9velopp\u00e9es et massives.
