These molecules can affect reproductive function of animals. This study aimed to the toxicity of the fungicide mancoz\u00e8b on certain blood biochemical markers and seasonal reproduction of male domestic pigeons (Columba livia domestica) under long photoperiod (20L: 04D). The fungicide was orally administered at 2 and 5 g\/l (doses used in agriculture). The obtained results revealed that under a long photoperiod, the sexual activity lasted only 04 weeks. In addition, mancozeb administration induced gonadic regression, delayed the refractory phase, provoked a hyperglycemia, a hyperlipidemia, an elevation in the activity of alkaline phosphatase and aminotransferase, and a reduction in creatinine level. The toxic effects of mancozeb was apparent in higher doses. To conclude, mancozeb has inhibited the reproduction mechanism in male pigeons and altered hepatic function.<\/p>\n Keywords: <\/em><\/strong>Mancozeb, pigeon, saisonal reproduction, photoperiod, biochemical markers.<\/p>\n","protected":false},"excerpt":{"rendered":" Num\u00e9ro de la revue: Volume 30 , Num\u00e9ro 1 1*Souheila Slimani,1 Badis Aouzal, 2Cherif Abdennour \u00a0and 2Mohamed Salah Boulakoud 1 Laboratory of Interaction Research, Biodiversity, Ecosystems and Biotechnology, Faculty of Sciences, University 20 August 1955 Skikda, Algeria. 2Laboratory of Animal … Lire la suite ![\"p2\"](\"\/wp-content\/uploads\/2014\/04\/p2.jpg\")
