Evaluasi Status Mineral DCAD Pakan Sapi Perah Pre-partum dan Post partum di KPSBU Lembang

Abstract

Sapi pada masa transisi seringkali mengalami penurunan daya tahan tubuh akibat adanya perubahan fisiologis dan metabolik pada tubuh sapi. Salah satu penyakit yang sering ditemui pada sapi pada masa transisi adalah hipokalsemia. Gangguan metabolisme pada sapi transisi dapat diatasi menggunakan DCAD (Dietary Cation Anion Difference). Peubah yang diamati berupa kandungan nutrien pakan, pemberian dan kecukupan pakan, kandungan mineral pakan, status DCAD pakan serta hubungannya dengan performa ternak. Rasio pemberian pakan di KPSBU pada sapi pre-partum 50:50 dan post-partum 54:46. Kecukupan nutrien di KPSBU sudah hampir memenuhi seluruh kebutuhan ternak. Status DCAD sapi transisi di KPSBU masih belum sesuai saran pemberiannya dimana DCAD sapi pre-partum adalah (4,2±211) sementara DCAD sapi post-partum adalah (-42,0±170,3). Rata-rata produksi susu harian di KPSBU adalah 17 L/hari. Gangguan metabolik pada sapi pre-partum sebesar 13,3% dan post-partum sebesar 46,7%. Reformulasi ransum, penambahan mineral pada pakan berupa pakan aditif atau garam kationik dan anionik diharapkan dapat memperbaiki status DCAD sapi transisi di KPSBU.

Cows during the transition period often experience a decrease in body resistance due to physiological and metabolic changes in the cow's body. One disease that is often encountered in cows during the transition period is hypocalcemia. Metabolic disorders in transitional cows can be overcome using DCAD (Dietary Cation Anion Difference). The parameters observed were feed nutrient content, feed provision and adequacy, feed mineral content, feed DCAD status and its relationship with animal performance. Feeding ratio at KPSBU for cattle pre-psrtum 50:50 and post-partum 54:46. Nutrient adequacy at KPSBU has almost met all livestock needs. The DCAD status of transitional cattle at KPSBU is still not in accordance with the recommendations for granting DCAD cattle pre partum is (4.2±211) while DCAD of cattle post-partum is (-42.0±170.3). The average daily milk production at KPSBU is 17 L/day. Metabolic disorders in cattle pre-partum of 13.3% and post-partum amounting to 46.7%. Diet reformulation, adding minerals to the feed in the form of feed additives or cationic and anionic salts is expected to improve the DCAD status of transition cattle at KPSBU.
