Feromonların Sığır Yetiştiriciliğinde Kullanımı Üzerine Çalışmalar

Öz

Feromon terimi, bir hayvan tarafından harici olarak idrar, dışkı veya deri bezlerinden salgılanan ve aynı türün alıcısında belirli bir reaksiyona neden olan hava yoluyla ulaşan kimyasal maddeleri ifade etmektedir. Feromonlara tepki, belirli bir davranış veya alıcı endokrin veya üreme sisteminde fizyolojik değişim süreçlerini içerir. Bunlar endokrin sistem üzerinden bir davranışın engellenmesi, uyarımı veya hazırlanması için gerekli fizyolojik olayları tetikleyen maddelerdir. Genellikle, birçok türün dişi idrar ya da vajinal salgılarında olduğu ve türün erkeklerinde kokuya bağlı farklı tepkilere neden olan koku işaretleri olarak bilinir. Bu işaret kokuları östrus ve proestrus dönemlerinde salınmakta olup başka dönemlerde bulunmazlar. Dişi idrar ve dış genital bölgesini koklayan erkek birey bu şekilde dişinin kızgınlık dönemi hakkında net bilgi sahibi olmaktadır. Bu çalışmanın amacı sığır yetiştiriciliğinde üreme performansının etkenliğini artırmak amacıyla sığır üreme feromonları, özellikleri ve biostimulationun rolü ile bu konuda yapılan çalışma sonuçlarının derlenmesi amaçlanmıştır

The studies on Pheromones and Using Possibilities in Cattle Reproduction

Öz

The term pheromone refers to air-borne chemical substances that are secreted externally by an animal in urine, feces or secreted by cutaneous glands and cause a specific reaction in a receiving individual of the same species; the reaction involves either the release of a specific behavior or physiological change in the recipient’s endocrine or reproductive system. These are substances that cause physiological events either through inhibition or stimulation in which endocrine, reproductive and other systems could be altered. Usually, it involves an olfactory cue that elicits a measurable physiological response. Olfactory cues that transmit specific information and result in specific and immediate behavioral responses in the male appear to be produced in the urine or vaginal secretions of females of many species. These odors are present at oestrus and proestrus but not at any other time. The male, through investigation of the female’s urine and anogenital region can use these olfactory cues to determine the stage of the female’s oestrus cycle. The aim of this study is to examine the role of pheromone(s) and biostimulation in cattle reproduction that would provide information of interest for cattle husbandry for enhancing reproductive performance
