AI Summary & Key Takeaways

AI Insight
⚡ TL;DR(Too Long; Didn't Read)

Results showed that diet supplementing with L-glutamine significantly increased egg mass, egg production, egg weight, shell thickness, haugh unit, levels of follicle-stimulating hormone and luteinizing hormone, hatchability and one-day chick weight and also improved feed conversion ratio compared with control1 and 2 diets (P<0.01).

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The present study was conducted to investigate the effect of dietary supplementation of L-glutamine and synergistic effects between glutamic acid in wheat and glutamine on productive performance, egg quality characteristics, blood biochemical parameters and fertility traits of guinea fowls fed with corn-soybean meal-wheat based diets. 120 guinea fowls (Numida meleagris) were allocated to a completely randomized design with six treatments consisted of four replicates and 5 birds per replicate.
📊
Key Findings & Data:Treatments were included: 1) corn-soybean meal based diet (control1), 2) corn-soybean meal-wheat based diet- (control2), 3) control1 containing 0.5% L-glutamine, 4) control1 containing 1% L-glutamine, 5) control2 containing 0.5% L-glutamine, 6) control2 containing 1% L-glutamine.
💡
Conclusion & Impact:Results showed that diet supplementing with L-glutamine significantly increased egg mass, egg production, egg weight, shell thickness, haugh unit, levels of follicle-stimulating hormone and luteinizing hormone, hatchability and one-day chick weight and also improved feed conversion ratio compared with control1 and 2 diets (P<0.01).

Abstract

The present study was conducted to investigate the effect of dietary supplementation of L-glutamine and synergistic effects between glutamic acid in wheat and glutamine on productive performance, egg quality characteristics, blood biochemical parameters and fertility traits of guinea fowls fed with corn-soybean meal-wheat based diets. 120 guinea fowls (Numida meleagris) were allocated to a completely randomized design with six treatments consisted of four replicates and 5 birds per replicate. Treatments were included: 1) corn-soybean meal based diet (control1), 2) corn-soybean meal-wheat based diet- (control2), 3) control1 containing 0.5% L-glutamine, 4) control1 containing 1% L-glutamine, 5) control2 containing 0.5% L-glutamine, 6) control2 containing 1% L-glutamine. Results showed that diet supplementing with L-glutamine significantly increased egg mass, egg production, egg weight, shell thickness, haugh unit, levels of follicle-stimulating hormone and luteinizing hormone, hatchability and one-day chick weight and also improved feed conversion ratio compared with control1 and 2 diets (P<0.01). The best response for fertility traits was achieved in birds fed with control2 containing 1% glutamine. It can be concluded that 1% glutamine has positive effects on performance, some egg quality traits and fertility parameters. Positive synergistic effect between wheat and glutamine on fertility traits can be valuable in guinea fowls.

Özet

Bu çalışma mısır-soya fasulyesi-buğday ile beslenen Gine tavuklarında diyete L-glutamin ilavesinin ve buğdaydaki glutamik asit ile glutamin arasındaki sinerjistik etkinin verim performansına, yumurta kalitesi parametrelerine, kan biyokimyasal değerlerine ve fertilite üzerine etkilerini araştırmak amacıyla yapılmıştır. Çalışmada 120 Gine tavuğu (Numida meleagris) tamamen rastgele dizaynda olmak üzere dört tekrar ve her tekrarda 5 tavuk olacak şekilde altı çalışma grubuna ayrıldı. Uygulamalar şu şekilde gerçekleştirildi: 1) mısır-soya fasulyesi temelli diyet (kontrol 1), 2) mısır-soya fasulyesi-buğday temelli diyet (kontrol 2), 3) %0.5 L-glutamin içeren kontrol 1, 4) %1 L-glutamin içeren kontrol 1, 5) %0.5 L-glutamin içeren kontrol 2, 6) %1 L-glutamin içeren kontrol 2. Elde edilen sonuçlar, L-glutamin ilave edilen diyet ile beslenen tavuklarda yumurta kütlesinde, yumurta üretiminde, yumurta ağırlığında, kabuk kalınlığında, Haugh biriminde, folikül stimüle edeci hormon ve luteinize edici hormon seviyelerinde, yumurtadan çıkma oranı ve bir günlük civciv ağırlıklarında anlamlı derecelerde artış olduğunu gösterdi (P<0.01). Ayrıca yem konversiyon oranı kontrol 1 ve 2 ile karşılaştırıldığında iyileşme göstermekteydi. Fertilite için en iyi değerler %1 glutamin içeren kontrol 2 ile beslenen tavuklarda gözlemlendi. %1 glutaminin performans, bazı yumurta kalitesi özelliklerine ve fertilite parametrelerine pozitif etkisi olduğu kanısına varıldı. Buğday ve glutamin arasındaki pozitif sinerjistik etki Gine tavuklarında fertilite bakımından değerli olabilir.
