Abstract

Egg quality can determine the fertility and reproductive efficiency of chickens. Selective breeding of Kambro chickens might have influenced the egg quality. This study aims to determine the influence of a selective breeding program on the egg quality of two Kambro chicken generations, F1 Kambro (F2K)-crossbred and F2 Kambro (F2K)-inbred. Inbreeding coefficient (F) and rate of inbreeding (Fx) of F­2K chickens were calculated. The egg collection record was analyzed based on its productivity, phenotype, weight, index, and exterior egg quality parameters. Exterior egg quality parameters were analyzed with mathematical formulae. Egg productivity in Hen Day Production (HDP) of F1K and F2K chickens for 270-days, respectively, was 24% and 16.5%. The heterosis value of F2K chicken was -31.25% indicating an inbreeding depression in egg productivity. The egg phenotype of F2K was classified into light-brown, cream, brown, and white. The mean egg weight (EW) of F1K and F2K, respectively, was 53.34 ± 2.34-grams and 54.92 ± 9.25-grams, thus were classified as small eggs. The eggshape index of F1K and F2K, respectively, were dominated by sharp eggs and round eggs. Exterior egg quality parameters of F1K and F2K based on GMD could be used as a predictor variable, meanwhile Sp (r = 1, p<0.001) could not be used to describe the disposition of the regression curve. The Fx and F values of F2K, respectively, were 4.925% and 25% close to the tolerance level of inbred-line inbreeding depression. Inbreeding depression was correlated with productivity and egg characteristics depression between F1K and F2K. Parental selection in a selective breeding program must be based on several factors, including inbreeding depression, inbreeding coefficient, inbreeding rate, and egg quality. The implementation of genomic selection may provide a solution to minimalize the effect and fluctuations of Fx and F.

Abstract

Buah kurma mengandung berbagai macam senyawa seperti karbohidrat, vitamin, mineral asam lemak dan antioksidan. Penelitian ini bertujuan untuk mengetahui dan mempelajari morfologi otot pektoralis ayam petelur [gallus gallus gallus(linnaeus, 1758)] betina setelah pemberian infusa buah kurma (phoenix dactilifera l.) Penelitian menggunakan ayam petelur strain Lohmann Brown sebanyak 200 ekor yang masing-masing dibagi ke dalam 5 kelompok yaitu kelompok kontrol yang diberi air minum biasa (K0), kelompok AGP (Antibiotic Growth Promoter) dosis 50mg/kg pakan (55ppm), pemberian dosis 5 mg buah kurma/ml air minum (P1), pemberian dosis 10 mg buah kurma/ml air minum (P2), dan pemberian dosis 20 mg buah kurma/ml air minum (P3). Pengulangan dilakukan sebanyak 3 kali. Ayam dipelihara selama 4 minggu di dalam box container. Infusa buah kurma diberikan pada pagi hari dan pada sore hari diganti air biasa. Pengukuran berat badan dilakukan setiap 3 hari sekali. Setelah ayam berumur 4 minggu kemudian di euthanasi dan otot pektoralis ayam diambil lalu diukur luas otot kemudian dibuat preparat melintang untuk menghitung luas fasikulus dan luas miofibril. Hasil yang didapatkan dari penelitian ini yaitu berat badan ayam pada minggu ke-4 kelompok perlakuan P2 berbeda secara signifikan lebih tinggi dibandingkan kelompok kontrol. Berat otot, luas otot, luas fasikulus dan luas miofibril pada kelompok perlakuan P2 berbeda secara signifikan lebih tinggi dibandingkan dengan kelompok perlakuan lainnya. Kesimpulan yang didapat yaitu infusa buah kurma dosis 10 mg/ml air minum dapat digunakan untuk meningkatkan pertumbuhan ayam petelur dan meningkatkan performa otot pektoralis ayam petelur.
