Abstract

EFFECT OF TURNING  FREQUENCY AND EGG POSITION ON HATCHABILITY OF CHICKEN EGGS (Gallus gallus Domesticus). This study aimed to determine effect of turning frequency and egg position on the hatching ability of chicken eggs. Study was conducted using 162 eggs of local hens inserted into hatching machine withcapacity of 300 eggs and implemented for 24 days. The experimental design of the completely factorial randomized design was applied consisting of 9 treatments and 3 replications. The two treatment factors were turning frequency consisted of 2 times a day, 3 times a day, 4 times a day, and egg position of 300, 600, and 900. The results of the analysis show that the effect of the turning frequency did not show a significant effect (P>0.05) on hatchability. However, egg position had a significant effect (P<0.5) on hatchability. There was no interaction between turning frequency and egg position againt hatchability and mortality. The conclusion of this research was the turning frequency of 2 times  a day with egg slope position of 300 produced high hatchability and low level of mortality. Keywords : Egg turning frequency and position, hatchability, local hen.

Abstract

PHENOTYPE CHARACTERISTICS OF SOME QUANTITATIVE TRAITS OF NATIVE CHICKEN IN MINAHASA. This study aims to obtain a measure of the phenotypic character of the quantitative traits of native chickens in Minahasa, North Sulawesi. This research was useful as additional information about the quantitative character of native chickens in Minahasa as a reference in efforts to preserve genetic resources (SDG) both for the development of native chickens and other breeding purposes. The material used was 291 male and female native chickens that had been separated by age (6 months and above) and had reached adult sex in the Minahasa Regency. The research method used was descriptive analysis (average, standard deviation, coefficient of variation and correlation) and continued withT-test. Retrieval of data by direct observation and measurement of quantitative properties based on the observed parameters. The results of this study illustrate the phenotypic character of quantitative traits of male and female native chickens in Minahasa where the size of the FL (femur length) and WL (wing length) were not different or the same in both sexes. SC (shank circumference) and CL (comb length)   were     significantly  different (P<0.05), while the trait of TL (tibia length), SL (shank length), TFL (third finger length), CH (comb height) showed differences very significant (P<0.01). It can be concluded quatitavive characteristics of native chicken in Minahasa were diverse and correlate from high to low.Keywords: native chicken, phenotype, quantitative characteristics.

Abstract

EFFECT OF DUCK EGG WEIGHT ON FERTILITY, EMBRYO DEVELOPMENT AND HATCHING WEIGHT OF DAY OLD DUCK. This study was done to evaluate embryonic development for determination of egg fertility and hatching weight of day old duck (DOD). This study involved 160 eggs of duck with the average egg weight (EW) classified into 55g ≤  EW < 60g, 61g ≤ EW < 65g, 65g ≤ EW < 70g and 71g ≤ EW < 75g. Data collection was conducted over 28 days, as long as the period of hatching process. The design method used in this study was completely randomized design. Existing data were analyzed using analysis of variance. Treatments in this study were 4 treatments and 4 replications at each treatment. The variables measured were the percentage of egg fertility, embryo development and hatching weight. Results showed that duck embryo development during the hatching process was in good condition process. The results of variance analysis showed that treatments of egg weight did not affect significantly the percentages of egg fertility. The percentages of fertility were ranging between 85 – 95%. Hatching weights were ranging between 31g – 51g per DOD. Based on the results of this study, it can be concluded that egg weight had no effect on the process of embryonic development and fertility, except those for the hatching weight of DOD. Key words: Duck egg weight, embryonic development, fertility, hatching weight.

Abstract

THE DIVERSITY OF QUALITATIVE CHARACTERISTICS IN   NATIVE    CHICKEN  AROUND MINAHASA.  This study aims to determine the diversity of qualitative characteristics in native chicken around Minahasa Regency. A total of 292 adult chickens were used as samples taken randomly and analyzed using descriptive methods. The results showed that the phenotype frequency, color genotype and feather pattern were 0.000515. Trait frequencies of comb shape was 0.000458, cupping color was 0.9957, foot skin color was 0.9949, and spur shape was 0.000193. The degree of heterosigosity of qualitative characteristics of Kampung chickens in Minahasa on average was in the medium category (0.20) to high (0.50). The degree of heterosigosity of the phenotypic traits of native chicken in Minahasa indicated the relative low degree of inbreeding mating. Distribution of phenotypic inheritance of feather color, comb shape and shape of male foot spurs based on samples of native chicken populations were not in genetic equilibrium. The qualitative traits of native chickens in the Minahasa Regency showed a fairly high level of diversity. Key words: native chicken, qualitative characteristics.
