                            <p>Leptin bir obese (leptin; ob/LEP) gen ürünü olup, başta adipoz dokuolmak üzere çeşitli dokulardan salgılanan bir hormondur. Leptinin enerjimetobolizmasının düzenlenmesinde önemli bir rol oynadığı ve ruminantlarda kurumadde tüketimindeki rolü nedeniyle hayvansal üretim bakımından önemlifonksiyonlara sahip olduğu bilinmektedir. Buna rağmen ruminant türlerinde leptinhakkındaki bilgiler oldukça azdır ve bu hormon hakkındaki mevcut bilgilerinçoğu insan ve kemirgenlerden elde edilmiştir. Leptin konsantrasyonu yetersizbesleme koşullarında β-agonist enjekte edilmesi durumunda azalmagöstermektedir. Plazma leptin konsantrasyonu vücut kondüsyonu,&amp;nbsp; pozitif enerji dengesi veya yeterli beslemedüzeyi ile pozitif ilişkilidir. Plazma leptin konsantrasyonu aynı zamanda tür,ırk, gebelik, laktasyon, genotip ve çevresel koşullara bağlıdır. Son yıllardaleptin genindeki polimorfizmlerin de plazma leptin konsantrasyonu üzerindeetkili olduğu düşünülmektedir. Bu çalışmada yetişkin ruminatların adipozdokularında ve meme bezlerindeki leptin gen ekpresyonunda veözellikle plazma leptin konsantrasyonlarında değişikliklere etkieden faktörler değerlendirmektedir.&amp;nbsp;</p></trans-abstract>
