Abstract

This paper is aimed to review the development of genetic evaluation on dairy cattle based on milk production, including recording system, mathematical model of the milk curve, genetic parameters, and genetic model for predicting breeding values. Test day is the best system to record milk yield as it can be used to predict lactation curve and genetic parameters. Ali-Schaeffer curve was the best curve to estimate milk yield (r > 0.99). Fixed and random regression models have been widely used to give more advantages in breeding program. The models are able to analyse the records measured at different stage of lactation, and  to predict a total breeding value from incomplete and part records. For practically used, fixed regression model (MRT) is suggested because it does not have numerical problem and is easier to be used.   Key words: Dairy cattle, breeding value, test day, random regression, fixed regression

Abstract

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

Abstract

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.  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

Abstract

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.

Abstract

Salah satu sumber daya genetik di Indonesia untuk mendukung kemandirian penyediaan pangan sebagai sumber protein hewani nasional adalah ayam lokal. Penelitian ini memiliki tujuan untuk mengetahui tentang konsumsi ransum, konversi ransum serta kurva pertumbuhan bobot badan ayam Sentul Debu dan Kelabu di BPPTU Jatiwangi. Penelitian menggunakan metode deskriptif kuantitatif di BPPTU Jatiwangi selama 12 minggu. Pada penelitian ini digunakan DOC (day old chick) ayam Sentul Debu 121 ekor dan DOC ayam Sentul Kelabu 124 ekor, yang dipelihara di kandang postal. Penimbangan bobot badan dilakukan mulai dari umur 1-12 minggu. Hasil penelitian ayam Sentul Debu menunjukkan rataan konsumsi ransum sebesar 629,09±23,40 selama pemeliharaan 12 minggu, rataan konversi ransum sebesar 5,97±4,75 dan penghitungan kurva pertumbuhannya mengikuti model Logistik 23,68±0,99. Hasil penelitian ayam Sentul Kelabu menunjukkan rataan konsumsi ransum sebesar 636,11±23,67 selama pemeliharaan 12 minggu, rataan konversi ransum sebesar 5,57±3,18 dan penghitungan kurva pertumbuhannya mengikuti model Logistik 16,11±0,99.

Abstract

Sapi perah adalah ternak ruminansia besar sebagai penghasil susu dan sumber protein hewani untuk memenuhi gizi masyarakat. Susu yang dihasilkan setiap ekor ternak jumlah produksinya berbeda-beda. Produksi susu sangat dipengaruhi oleh umur, pakan, pemerahan, dan periode laktasi. Penelitian telah dilaksanakan di Balai Perbibitan dan Pengembangan Inseminasi Buatan Ternak Sapi Perah Bunikasih Cianjur. Tujuan penelitian untuk mengevaluasi jumlah produksi susu sapi FH pada laktasi 1-4. Metode penelitian menggunakan analisis deskriptif kuantitatif dengan mengukur rata-rata, simpangan baku, koefisien variasi, minimal, dan maksimal. Sampel yang digunakan catatan data produksi susu tahun 2017-2018. Hasil menunjukkan bahwa rata-rata produksi susu pada sapi FH berturut-turut yaitu laktasi pertama sebesar 12,56 liter/ekor/hari, periode laktasi kedua 14,82 liter/ekor/hari, periode laktasi ketiga 15,49 liter/ekor/hari, dan laktasi keempat 14,62 liter/ekor/hari, nilai minimal dan maksimum produksi susu 4,5-31 liter dengan koefisien variasi 0,00219-0,00357. Jumlah produksi susu sapi perah FH pada berbagai periode  di BPPIBTSP Bunikasih masih dalam kategori yang normal

Abstract

Sapi perah merupakan ternak ruminansia besar yang menghasilkan produk berupa susu. Produktivitas suatu ternak baik buruknya dilihat dari kualitas bibit yang dihasilkan. Pengabdian ini bertujuan untuk meningkatkan pengetahuan peternak dalam upaya menentukan kualitas bibit sapi perah yang baik. Tahapan pengabdian dilakukan melalui survey lapangan, studi literatur, penyuluhan dan demonstrasi melalui 2 metode yaitu perangkat media (tidak langsung) dan aplikatif terhadap ternak (langsung). Penyuluhan telah dilakukan pada kelompok ternak sapi perah binaan Balai Perbibitan dan Pengembangan Inseminasi Buatan Ternak Sapi Perah (BPPIBTSP) Bunikasih Kecamatan Warung kondang Kabupaten Cianjur yang dihadiri oleh 50 peserta dari berbagai kalangan umur kemudian dilanjutkan dengan demonstrasi. Hasil menunjukkan bahwa penyuluhan dapat meningkatkan pengetahuan tentang cara  mengetahui kualitas bibit yang baik hal ini terlihat dari jawaban kuisioner pre test dan post test. Kesimpulan bahwa penyuluhan dapat meningkatkan pengetahuan kualitas bibit sapi perah di kelompok peternak binaan BPPIBTSP Bunikasih sehingga mampu menentukan kualitas bibit unggul yang baik melalui karakteristik dari ternaknya.Kata kunci : kualitas bibit sapi perah, kelompok ternak, BPPIBTSP, Cianjur
