SEXING BERDASARKAN MORFOLOGI BURUNG PUYUH (Coturnix coturnix japonica)

ABSTRACT JAPANESE QUAIL (Coturnix coturnix japonica) SEXING BASED ON MORPHOLOGY. The purpose of this research was to determine the success of sexing if done earlier. This research was conducted in the cages of a quail farm from April 1st 2014 until May 18th 2014. The materials used were 110 male and female day old quails for the first repetition and 100 male and female day old quails for the second repetition, commercial feed CP 11, vitastress. The equipments used in this research were 60 watt light bulb, brooder, digital scale, and a digital camera.The observation was conducted from the first day when the quails just hatched until the quails were 3 weeks of age. The data were analayzed in a descriptive way. The results showed that sexing morphologically can be done in day one with a success rate of 92,72%. Keywords : Quails, sexing, morphology

ABSTRACT Serum concentrations of testosterone, 5α-dihydrotestosterone, oestradiol and progesterone were measured by radioimmunoassay combined with Celite chromatography in male and female Japanese quail (Coturnix coturnix japonica) during the second half of embryonic life (days 9–17 of incubation) and during the first 5 weeks after hatching. The mean level of each of the four steroids was significantly affected by the age of the birds. An overall effect of sex was detected by analysis of variance only on oestradiol concentrations, with females having higher serum concentrations than males during most of the age range studied. Significant peaks of testosterone and progesterone were also detected around hatching time. These results are consistent with the view that oestradiol is the major hormone implicated in the sexual differentiation of reproductive behaviour in the quail. The relationships between the circulating concentrations of oestradiol during ontogeny and the critical period of differentiation as postulated by currently accepted models is also discussed. J.

Japanese quail (Coturnix coturnix japonica) is one of the livestock sectors that is efficient in providing nutrition, both from eggs and meat. This study aims to examine the effect of provision of standard organic feed and organic feed containing cassava leaves, turmeric powder and ginger on increasing the percentage of carcasses and internal organs Japanese quail (Coturnix coturnix japonica). This study used an experimental method with a completely randomized design pattern. The test animals used were 30 females Japanese quail which were divided into 3 groups, i.e. P0: control (given commercial feed); P1: given standard organic feed (corn, soybeans, bran and fish meal); P2: given organic feed (corn, soybeans, bran, fish meal, cassava leaves, turmeric and ginger powder). Each group was treated with 5 replications. Data obtained were analyzed using analysis of variance (ANOVA) and continued with Duncan test with a confidence of 95% (P>0.05). The results showed that the provision of organic feed could not increase the percentage of carcass, heart and liver, but could increase the percentage of Japanese quail gizzard (Coturnix coturnix japonica).
