Judul: Kualitas Telur Tetas dan Perkembangan Somite (Tulang Belakang) pada Embrio Ayam Arab dari Umur Induk yang Berbeda
Abstrak: Arab chicken is one of the most favorite local layer chicken developed in Indonesia due to their high productivities. The egg qualities are highly influenced by the hen age. Somitogenesis is an early step in chick embryo development. The data of somite development on chick embryo is very limited, especially in Arab chicken. Therefore this research aimed to analyze the influence of hen breeder age on formation of somites. There were 99 eggs from 36, 42, and 54 weeks of hen age will be used in this study. The embryo samples were harvested in 24, 33, and 48 hours after incubation. The Complete Randomized Design was used to analyze exterior and interior of egg qualities such as the egg weight, egg shape index, shell weight and shell thickness. The number of somites will be analyzed descriptively. The results show that hen age had effect significantly the egg weight and the shell thickness (P<0,05). Hen age did not affect the egg shape index and the shell weight (P>0,05). There were died embryos from hen age of 54 weeks (22%) and 42 weeks (15,38%). The embryo from 42 week of hen age developed slower (15,38%) than embryo from 36 and 54 weeks.

Judul: Perkembangan Embrio dan Daya Tetas serta Viabilitas Anak Ayam Arab dari Umur Induk yang Berbeda
Abstrak: Low quality and quantity of local chicken egg in Indonesia are mainly due to the poor breeding management. Hen age is one of considered factor of breeding and hatchery management. Until now the embryo development, hatchability, and chick viability of local chicken such as Arab chicken from different age is still questionable, although it has been proven on broilers. This research was conducted at Laboratory of Poultry Hatching, Departement of Animal Science Production and Technology, Animal Science Faculty, Bogor Agricultural University from May till June 2012. The Complete Randomized design with 135 fertile eggs from three different age of hens (36, 42, and 54 weeks) used in this study. Exterior quality of fertile eggs, embryo development, hacthability, and chick viability were observed in this study. The data were analyzed by analysis of variance (ANOVA) and then continued by Tuckey analysis. Data of shell cleanness, air egg shell quality, extraembrionic membrane development, hatchability, and viability were analyzed by descriptive method. The data showed that egg weigth, egg index, and embryo weight, beak length, head perimeter of 7th incubation time and embryo weight, neck length, and leg length of 14th incubation time were different (P<0.05). Incressing of hen age could effect the decressing embrio capability to absorb nutrition. The temperature of incubator also effected on metabolism rapidity of embrio. The optimum hen age of to produce good embryo development, hatchability, and viability of Arab Day Old Chick is 36 weeks.
