Yumurta Tavuklarında Yaş ve Verimin Serum Gama-GT, GOT, ve CK Düzeylerine Etkisi

Bu çalışmada yumurta tavuklarında yaş ve verimin serum Gama-GT, GüT,GPT ve CK düzeyleri üzerine etkil~ri incelenmiştir. Bu amaçla 50 adet . yumurtacı civciv kullanılmıştır. Hisex Brown hibrit civcivlerinden 3 günlükten yumurta veriminde pike ulaşınca ya dek kan serumu alınınışı tr. Hayvanlar ı 7. haftada yumurtlamaya başlamışlar ve yumurta verimi %94.3 ile 29. haftada pike ulaşmıştır. Gama-GT düzeyi 7., 10. ve 27. haftalarda yükselmiş, diğer haftalarda ise önemli farklılıklar meydana gelmemiştir. İlk dört haftada yüksek olan GüT düzeyi 7. haftada düşmüş, enzimin düzeyinde 7, 1O ve 12. haftalarda önemli bir değişiklik olmamıştır. Yumurta üretimine geçiş öncesi olan 15. haftada yükselme, 19. haftada düşme meydana gelmiştir. Bundan sonraki haftalarda yavaş yavaş artarak yumurta veriminde pike ulaşılan 29. haftada önemli bir yükselme meydana gelmiştir. GPT düzeyinde 12. ve 25 . haftalardaki düşüş dışında önemli bir farklılık görülmemiştir. CK düzeyinde 12. haftada önemli bir düşme,10, 15 , 19, 25 . haftalarda yükselme meydana gelmiştir.

The Effekts Of Age and Egg Produktuon On Serum Gama-GT,GOT,GPT and CK Leves İn Layers

In this study, the effect of age and egg production on serum GOT, GPT, gama-GT and CK levels were investigated. Commercialy available strains of 50 Hisex Brown chicks were used and sera of animals were collected from 3 · days untill the pik Jevel of egg production. Egg production started at 17. week and piked with 94.3 %at 29. week. No significant differences were found in gama-GT levels except teh increases at 7 27. weeks. The GOT levels were high during the first fo ur weeks and decreased at 7. week Although no significant differences were seen 7., 10. and 12. weeks, atthe begininf of egg production (at 15. week) the enzyın levels increased and at 19. week it decreased. Thereafter, GOT levels increased gradually and at 29. week it significantly increased. No significant differences were found in GPT levels except the decrease at 12. and 25 weeks. The Ok levels decreased markedly at 12. week and increased at 10., 15., 19. and 25 . weeks.
