Abstract

Ransum yang diberikan ditambahkan premix yang bermanfaat untuk pertumbuhan serta produksi susu sapi perah. Tujuan penelitian adalah untuk mengetahui produksi susu dan kualitas susu sapi perah yang ditambahkan premix dalam ransum. Metode yang digunakan dalam penelitian adalah rancangan acak kelompok (RAK) dengan tiga macam perlakuan pemberian premix sebanyak 90 gram, pemberian premix sebanyak 70 gram, pemberian premix sebanyak 50 gram masing-masing diulang sebanyak 6 ulangan. Hasil penelitian menunjukkan bahwa pemberian 50 gram premix berpengaruh nyata terhadap produksi susu sapi Friesien Holstein dengan jumlah 19,41 liter/ekor/hari sedangkan terhadap kualitas susu (berat jenis, kadar lemak, protein) memberikan pengaruh tidak nyata. Pemberian premix sebanyak 50 gram dapat meningkatkan jumlah produksi susu tetapi tidak mampu meningkatkan kualitas susunya.Kata kunci: premix, produksi susu, kualitas susu, sapi FH

Abstract

Research on the effect of influence of experience and age of the artificial insemination officer on the success of artificial insemination (AI) in dairy cows has been conducted. This study aims to determine and examine the ef- fect of influence of experience and age of the artificial insemination officer on the success of artificial insemination (AI) in dairy cows. The research was conducted in December 2022–January 2023 in Lembang District, Bandung Barat. The method used is the survey method. The material used was an artificial insemination officer at the Kope- rasi Peternak Sapi Bandung Utara (KPSBU) Lembang. The variables observed to determine AI success are service conception (S/C), conception rate (C/R). The data analysis used in this study is quantitative descriptive analysis and simple correlation analysis. The results showed that the AI officer experience was an average of 19 years and an average age of 39 years. Average S/C value is 1.84 , Average C/R value is 64.50%. The results of a simple correlation analysis showed that the experience and age of the inseminator had no real effect (P>0.05) on the success of AI in dairy cows. It was concluded that the success rate of AI in dairy cattle based on S/C and CR in Lembang District was good, but the experience and age of the artificial insemination officer did not have a significant effect on the success of artificial insemination in dairy cows.
