Evaluasi Status Dietary Cation-Anion Difference pada Sapi Pre-Partum dan Post-Partum terhadap Performa Sapi di Koperasi Peternakan Bandung Selatan Pangalengan

Abstract

Hipokalsemia merupakan salah satu gangguan metabolik yang umum terjadi pada sapi perah fase post-partum. Gangguan ini dapat dicegah dengan mengatur kandungan dietary cation-anion difference atau DCAD pada pakan. Dietary cation-anion difference perlu diperhatikan dari fase pre-partum sapi perah. Penelitian ini bertujuan untuk mengamati status DCAD pada masing-masing 15 sapi pre-partum dan post-partum di KPBS Pangalengan. Hasil penelitian menunjukkan DCAD sapi pre-partum bernilai -205,8±238,5 mEq/kg BK dan post-partum bernilai -164,34±175,38 mEq/kg BK. Sebanyak 86,67% sapi fase pre-partum sudah sesuai dengan kebutuhan DCAD bernilai negatif sedangkan hanya 18,75% sapi post-partum yang sudah sesuai dengan kebutuhan DCAD bernilai positif. Hasil uji korelasi menunjukkan adanya korelasi lemah antara DCAD dengan performa ternak berupa pH urin, gangguan metabolik, produksi susu, dan kualitas susu. Berdasarkan hal tersebut dapat disimpulkan bahwa manajemen DCAD sapi post-partum belum sesuai sehingga diperlukan penyesuaian terhadap pakan ternak dengan suplementasi atau reformulasi ransum.

Hypocalcemia is one of the metabolic disorders that commonly occurs in dairy cows during the post-partum phase. This disorder can be prevented by regulating the dietary cation-anion difference profile in their diet. The dietary cation-anion difference profile needs to be managed from the pre-partum phase. This research aims to observe the DCAD profile in both 15 pre-partum and post-partum cows at KPBS Pangalengan. The research found that DCAD in pre-partum cows had a value of -205.8±238.5 mEq/kg DM and for the post-partum cows ware -164.34±175.38 mEq/kg DM. As many 86.67% of pre-partum cows had the appropriate negative DCAD values, while only 18.75% of post-partum cows has the appropriate positive DCAD values. Correlation tests showed a weak correlation between DCAD and the cow’s performances such as urine pH, metabolic disorder, milk production, and milk quality. Based on these, it can be concluded that DCAD management of the post-partum cows are not optimal, necessitating adjustments in cow’s feed through supplementation or diet reformulation.
