Two lines of native chicken (Kampung and Pelung cross) were subjected to diets differed in protein content (21, 19, 17and 15%), but isocaloric (2,900 kcal ME/kg). Ten (5 males, 5 females) day old chicks were allocated as replicate and thetreatments were 2 lines x 4 levels dietary protein. The trial was conducted for 12 weeks period . Bodyweight gain of Kampungchicken (704 g/bird) was lower than ofPelung cross chicken (844 g/bird). Based on bodyweight gain and feed conversion ratio,the optimum level of dietary crude protein was 19% for both lines, whilst consumption was not affected either by lines nor bydietary protein. Pelung cross chicken converted feed to body weight more efficiently than Kampung chicken did. However feedconversion ratio increased with decreasing in dietary protein. Mortality was not affected either by lines nor by dietary protein.Twelve weeks carcass percentage of Pelung cross (64,9%) was higher than of Kampung chickens (62,9%), however carcass percentage was not affected by the dietary protein. Abdominal fat pad was not affected by lines of chickens nor dietary protein. Â Key words : Native chicken, protein, growth, carcass

alternative to increasing productivity and production efficiency. Crossbreeding has been used widely for increasing productivity, and in this experiment Alabio and Mojosari ducks were crossed reciprocally in order to evaluate their egg production and egg quality, when compared to their parental breeds. Four genotypes AA, AM, MA and MM were compared and each consisted of 50 layer ducks. Each animal was kept in individual cage, and individual egg production and egg quality were recorded. They were given layer feed containing 20% crude protein and 3000 kcal/kg metabolisable energy. Results showed that the crossbred ducks (AM and MA) laid eggs earlier than their parental breeds (AA and MM), and MA laid earlier than AM. The weight of first eggs of the crossbreeds did not differ significantly, AM was the same as MM and MA the same as AA. For the body weight at first lay, MA and AM weighed in between their parental breeds, AA was the heaviest and then followed by MA, AM and MM. For the 3-month egg production, MA ducks laid significantly more egg than the other 3 genotypes, and this is related to the age of first lay being the earliest. In terms of egg quality such as egg weight, yolk color, weight and thickness of shell, weight of the white and HU value, the crossbred ducks showed quality in between AA and MM. The AM ducks tended to be closer to MM and MA closer to AA, and this shows a strong influence of maternal effects. The average level of heterosis for weight of first egg is 2.41% and for 3-month egg production is 2.1%, but for MA cross the heterosis level is 11.69% for egg production. The overall results showed that crossbreeds between Alabio and Mojosari have the potential in improving production traits in the effort to increase productivity and production efficiency.

Effect of genotypes and aflatoxin levels in the diets on early laying characteristics of local ducks Prasetyo, L. Hardi; Susanti, T

Layer ducks are known for their sensitivity to aflatoxin contamination in their diets, and this has been causing problem in egg productivity of local ducks due to feeding system practiced by traditional farmers. This study was aimed at exploring the level of sensitivity of Mojosari and Tegal ducks to different aflatoxin levels in their diets, especially on characteristics during early laying period. Three hundreds and nine female Mojosari ducks and 260 female Tegal ducks were used in this study. Two levels of aflatoxin in the diets, 0 and 150 ppb, were given to 4 week-old ducklings for 4 weeks. Observations were taken on age at first laying, body weight at first laying, and egg qualities as early indications of the egg production potentials. The results showed that different levels of aflatoxin in the diets only affected live weight at first laying, and not age at first laying. The two genotypes differed significantly in egg weight, yolk weight, and shell weight. It is concluded that aflatoxin contamination in the diets during early growth did not really affect characteristics of early laying of Mojosari and Tegal ducks. Key Words: Local Ducks, Aflatoxin
