Effect of transgenic and non-transgenic corn hybrids on the performance of quails and chicken: A review: Pengaruh hibrida jagung transgenik dan non-transgenik terhadap performa puyuh dan ayam: Review
No full textAbstrak
Ayam broiler, layer dan puyuh (Coturnix japonica) adalah jenis unggas yang semakin populer untuk dipelihara karena performa yang baik seperti produksi yang cepat, dan kemudahan perawatan, baik untuk penghasil daging dan telur di berbagai negara Asia dan di dunia. Unggas sering dipelihara dengan menggunakan jagung (Zea mays) sebagai sumber energi utama dalam ransum. Namun, dalam produksinya, jagung sering menghadapi masalah yang melibatkan hama arthropoda seperti Ngengat Penggerek Jagung Asia (Ostrinia furnacalis), dan oleh karena itu, teknologi rekayasa dalam bidang pertanian telah banyak mengembangkan banyak galur jagung transgenik yang telah ditanam dan dibiakkan agar tahan terhadap hama ini. Artikel ini bertujuan untuk mengetahui kinerja jagung transgenik sebagai pakan, keamanan dan kesetaraan gizi pada unggas baik sebagai penghasil daging maupun telur. Hasil review, menunjukkan bahwa di berbagai penelitian, tidak ada perbedaan yang signifikan antara parameter produksi pada ayam pedaging, petelur dan puyuh yang diberi pakan jagung non-transgenik konvensional dan transgenik. Kesamaan ini terlihat pada jenis unggas pedaging dan petelur. Penelitian untuk menganalisis efek jagung transgenik pada parameter komposisi kuning telur, dan komposisi otot ayam pedaging masih perlu dilakukan. Hasil kajian ini juga mengamati bahwa tidak ada gen dan protein transgenik yang tersisa setelah pemotongan unggas di dalam otot dan jaringan, yang menunjukkan bahwa masalah keamanan gen dan protein transgenik tidak ditransfer dari jagung ke produk unggas.

Abstract
Broiler, Layer and Japanese Quail (Coturnix japonica) are species of poultry that have become increasingly popular to raise due to their performance such as fast production, and ease of care, either for meat and egg producers in many Asian countries and worldwide. As poultry, they are often raised using corn (Zea mays) as the primary energy source in the ration. However, corn often faces problems involving arthropod pests such as the Asian Corn Borer Moth (Ostrinia furnacalis), and as such, agricultural engineering technology has developed many strains of transgenic corn that have been grown and bred to be resistant to these pests. This article aimed to determine the transgenic corn performance as feed, safety and nutritional equivalence on poultry (quails and chicken) for meat and egg producer. The review determined that across various studies, there were no significant differences between production parameters in the broiler, layer and quails fed a conventional non-GMO diet and entirely transgenic corn. This similarity was seen in both meat and layer types. Though, research still needs to be done to assess transgenic corn's effects on parameters of yolk composition and breast muscle composition. The study also observed that no transgenic genes and proteins remained after the slaughter of the poultry in the muscle and tissues, indicating the safety concerns of transgenic genes and proteins not being transferred from the corn to poultry.

Imunitas dan profil hematologi ayam persilangan pada pemberian protein pakan dan akses kandang pemeliharaan yang berbeda: Influence of dietary protein and rearing cage access to immunity and hematological profile of crossing chicken
No full textAbstract
This research aimed to determine the immunity and haematological profile of crossbreeds between Bangkok chickens and laying hens reared with access to indoor or outdoor cages and different dietary proteins. A total of 200 crossbreed chickens were randomly divided into 2 treatment factors, the first factor was the cage (A) (Indoor and Outdoor access) and the second factor was feed (B) (17% and 22% protein content). Each treatment had 5 replications; each replication consisted of 10 chickens. Observations were made on the relative weights of the bursa, thymus and spleen as well as the blood profile and heterophil-lymphocyte ratio (H/L). The results showed that feed and cages had no significant effect (P>0.05) on the relative weight of the bursa fabricius, the relative weight of the thymus and the relative weight of the spleen, while the interaction between feed and cage could affect the relative weight of the spleen. The haematological profile also did not show any difference due to the treatment of different feed protein content and cage access (p>0.05). These results indicate crossed chickens can adapt to indoor or outdoor cages with a minimum of 17% protein.

Get PDFAbstract
Amorphophallus companulatus (AC) is a plant from the Araceae family that contains high metabolizable energy and an alternative feedstuff for livestock. This study aimed to investigate the effect of feeding diet containing AC on slaughter weight, carcass weight, and abdominal fat of broiler chickens. The feeding trial lasted for 35 days. For the sample, 112 broiler chicks, all a day old (DOC) were used. The research had 4 treatment groups and 4 replications with 7 birds per replication. The four treatments were P0 (Control ration without AC); P1 (rations containing 5% of AC); P2 (rations containing 10% of AC); P3 (rations containing 15% AC). Slaughter weight, carcass weight, and abdominal fat weight data were analyzed by variance analysis and followed by Duncan's multiple range test with a confidence level of 0.05. The addition of AC tubers affected the slaughter weight, carcass weight, and abdominal fat weight of broiler chickens. The slaughter and carcass weight in chickens fed with the control ration was significantly (P <0.05) higher than the chicken fed with rations containing AC. The abdominal fat weight was significantly (P <0.05) higher in chickens fed with control rations compared to those fed with AC rations. In conclusion, AC tuber meal in the ration can reduce the slaughter weight, carcass weight, and abdominal fat weight of broiler chickens.
