Performa Produksi Sapi Dara Peranakan Ongole Pada Masa Rekondisi Dengan Pakan Fermentasi Dan Konsentrat

Abstract

Performa sapi dipengaruhi oleh beberapa aspek seperti manajemen pemberian pakan. Penelitian ini bertujuan mengkaji performa sapi dara Peranakan Ongole (PO) pada masa rekondisi dengan pakan fermentasi sorinfer sebagai substitusi konsentrat terhadap performa produksi sapi dara PO sebelum perkawinan inseminasi buatan. Sapi yang digunakan berupa sapi PO dara betina sebanyak 6 ekor umur 1–2 tahun (I0–I1) dengan rataan bobot awal sebesar 174,17±28,32kg. Penelitian ini menggunakan 2 perlakuan ransum yaitu konsentrat dan sorinfer. Peubah yang diamati berupa suhu dan kelembapan, Temperature Humidity Index (THI), konsumsi ransum as feed, bahan kering (BK), protein kasar (PK), energi (TDN), konversi ransum as feed, BK, pertambahan bobot badan (PBB), bobot akhir serta feed cost per gain (FCG). Data dianalisis kovarian menggunakan Statistical Analysis Software. Hasil penelitian menunjukkan konsumsi ransum as feed, BK, PK, TDN perlakuan sorinfer nyata lebih tinggi (P<0,05) dibandingkan dengan perlakuan konsentrat. Akan tetapi nilai konversi as feed, perlakuan konsentrat nyata lebih efisien (P<0,05) dibandingkan dengan perlakuan sorinfer. Sorinfer dapat digunakan sebagai pakan alternatif, meskipun PBB yang diberikan cukup rendah.

Cattle performance is affected by several aspect such as feeding management. This study aims to examine the effect of sorinfer silage as concentrate substitution on the production performance of Ongole Crossbreed (PO) heifers during the reconditioning period before artificial insemination mating. The cows used are PO heifers within the age of 1–2 years (I0–I1) female with an average initial weight of 174,17±28,32kg. This study used 2 ration treatments, concentrate and sorinfer. The observed variables included were temperature and humidity, Temperature Humidity Index (THI), consumption of as feed, dry matter (DM), crude protein (CP), energy (TDN), conversion of as feed, DM, body weight gain (BWG), final weight and feed cost per gain (FCG). Data were analyzed using analysis of covariance using Statistical Analysis Software. The results showed that the consumption of as feed, CP, DM and TDN in sorinfer were significantly higher (P<0.05) compared to the concentrate. However, the value of as feed conversion in concentrate was significantly more efficient (P<0.05) compared to the sorinfer. Sorinfer can be used as an alternative feed, although the BWG given is quite low.
