Genetic evaluation on milk yield production basically based on breeding value. This research was addressed to study milk production curve, for the most appropriate genetic evaluation, and the best methods in estimating genetic parameter and predicting breeding values. Data were collected from PT. Taurus Dairy Farm, consisting of 581 cows having 305 days records in first lactation (P305) and 542 cows having 305 days records in second lactation. Records used for Test Day (TD) evaluation were 5,373 for first lactation, and 4,925 for second lactation. Total records used for Test Day were 10,298. The results indicated that the most suitable curve, being able to be used for genetic evaluation was Ali-Schaeffer with the coefficient of correlation of 0.999, and the most appropriate model for estimation of genetic parameters and prediction of breeding values was fixed regression model with the regression of Ali-Schaeffer by taking account to the covariates. The genetic evaluation can therefore be conducted simultaneously by ignoring lactation levels. Key Words: Test Day, Milk Production Curve, Breeding Value, Dairy Cattle

Season, rainfall, day of rain, temperature, humidity, year and farm are fixed effects, which have been reported to influence milk yield. Those factors are often linked together to contribute to the variation of milk production. This research is addressed to study the fixed effect factors, including lactation curve, which should be considered for genetic evaluation of milk yield based on test day records of dairy cattle. The data were taken from four different farms, which were PT. Taurus Dairy Farm, BPPT Cikole, Bandang Dairy Farm, and BBPTU Baturraden. In total of 16806 test day records were evaluated, consisting of 9,302 at first and 7,504 at second lactation, respectively. The results indicated that fixed effects were very specific and the influences had different patterns for each farm. Consequently, in a genetic evaluation, these factors such as lactation, temperature, year, day of rain, and humidity need to be evaluated first.Â Ali-Schaeffer curve represented the most appropriate curve to use in the genetic evaluation of dairy cattle in Indonesia. Key words: Fixed Effects, Milk Production Curve, Test Day, Dairy Cattle

Basis populasi Sapi Pasundan di Kabupaten Majalengka hanya di Kecamatan Kertajatidan menyebar di sepuluh desa, namunsejak tahun 2014 mengalami degradasi daya dukung lahan akibat alih fungsi lahan hutan. Penurunan daya dukung ini mengakibatkan migrasi ternak ke luar wilayah. Tujuan penelitian ini dilakukan untuk mendeskripsikan frekuensi gen, nilai keseimbangan populasi dan Effective Population Size (EPS) pada Sapi Pasundan di Kabupaten Majalengka, sejak September sampai November 2015. Metode penelitian menggunakan metode deskriptif, pemilihan sampel ternak menggunakan stratified random sampling,dan pengukuran sebaran genotip menggunakan pola protein albumin darah. Struktur populasi diukur berdasarkan basis populasi pada wilayah yang menjadi daya dukungnya. Hasil penelitian menunjukkan bahwa penurunan daya dukung wilayah di Kecamatan Kertajati disebabkan oleh alih fungsi lahan menjadi Bandara Internasional dan Perubahan pola tanaman hutan dari Jati menjadi tanaman Karet. Hal ini menyebabkan migrasi ternak ke wilayah lain ke Sumedang dan Indramayu.

Muscovy duck development can be influenced by reproductive performance, including mating behavior. The purpose of the study was to obtain the quantitative characteristics of the Ciayumajakuning Muscovy duck mating and to obtain the best antog in its mating characteristics. The research method was carried out experimentally using a completely randomized design with 4 treatments and 5 replications. The parameters observed were mating frequency, mating duration, mating time, and mating location. The results showed that the quantitative characteristics of the antog Kuningan showed a significant difference in the frequency of mating with the drake and duck and the duration of mating was higher than that of the Cirebon, Indramayu, and Majalengka Muscovy duck. This is supported by data on the frequency of mating with 7.4 drake and duck 2 times/day, and the mating duration is 119.4 seconds. The mating time of the Cirebon, Indramayu, Majalengka, and Kuningan Muscovy duck did not show a significant difference, namely more in the first and second quarters at 06.01-12.00 WIB and 12.01-16.00 WIB. The mating location is in zone 1 in the area near the place of feed and drinking water. In conclusion, Muscovy duck Kuningan has the best marital characteristics.

Garut District is one of Pasundan Cows Population in West Java, The modus of population is the south coast. The aim of the research is to determinate about dispersion population of Pasundan cows at Garut District based on geographic condition themselves and migration pattern them. The research was done from December 2019 until January 2020 at basic population area. The method using is descriptive, so survey was done on area basic population based on topography, agronomy, temperature, rainfall, humidity and hydrology. The result of this research is the dispersion population of Pasundan Cows at Cibalong, Pameungpeuk and Cikelet sub district that have villages with sloping and flat topography (land slope under 450) on height from sea level under 500 hsl, air temperature 25-32 ºC on rain fall 2000-25000 mm/year. Their climatology adapted with agro climatology and hydrology on grazing. The hydrology is influenced Cikaso, Cibaluk and Cieurih River. Mekarmukti and Caringin Sub District are not basic population of Pasundan Cows, because two area is a exclusive gardeners. The migration among animal is influenced geographic condition it. Conclusion of this research is dispersion of Pasundan Cows Population is influenced the geographic condition, as agro climatology, topography, temperature, rainfall, humidity and hydrology that enveloping grazing area.

Biological characteristics covering qualitative and quantitative traits are essential to study phenotypic characteristics in livestock farming. This research investigates the quantitative attributes of Muscovy duck in Ciayumajakuning (Cirebon, Indramayu, Majalengka, and Kuningan Regency), West Java, Indonesia. Observations were conducted on 673 Muscovy ducks aged six months using a survey method with a sample selection of multistage probability stratified random sampling. Data analysis uses univariate and multivariate discriminant analysis. The quantitative data shows that the body size of a drake is more significant than the duck. Drake from Cirebon has a close kinship with Drake from Majalengka and Kuningan, but they have a distant relationship with Indramayu Muscovy ducks. Duck from Cirebon has a close kinship with ducks from Indramayu and Majalengka, but they have a distant relationship with ducks from Kuningan. It is concluded that the quantitative traits of the Muscovy duck in Ciayumajakuning are diverse. Keywords: Quantitative Traits, Muscovy duck, Ciayumajakuning
