Abstract

Two hundred and thirty milk samples of different quarters taken from dairy cows around Bogor and Cipanas were used in this study. The milk samples were tested aseptically against subclinical mastitis using the MC and AMP in the field and in the laboratory. The amount of leucocytes were counted using the BREED method.Using the MC the sensitivity is 85.2% and the specificity is 97.8% in detecting subclinical mastitis. In comparing the use of MC to the AMP or to the BREED method no significant difference was found. The MC should be used routinely to detect mastitis especiallynew for cases of subclinical mastitis.

Abstract

The unpleasant odor of piggeries is mostly caused by the emission of ammonia and hydrogen sulfide. An experimentwas conducted to study the effect of decomposting microbes EM4 on the emission of ammonia and hydrogen sulfide. The manure was treated with four different concentrations of EM4@, 0'70, 0.5%, 1.0% and 1.5% respectively. The ammonia released was trapped in 0.02N boric acid and analyzed with Nessler method, while the hydrogen sulfide was trapped in 0.02N zinc acetate and analyzed with the methylene blue method. The study suggested that the high concentrationof ammonia and hydrogen sulfide gas were decreasedafter 14 days, and there was no significant differencesin either ammonia or hydrogen sulfide emission although theammonia emission decreased to under 20 ppm with of 1.5%EM^" and the hydrogen sulfide decreased to 0.202 ppmwith application of 1.0% EM4@.

Abstract

Mastitis subklinis hanya dapat dideteksi melalui pemeriksaan mikrobiologi dan penghitungan jumlah sel radang terhadap contoh susu. Penyakit ini sangat merugikan peternak karena produksi susu menurun dan seringkali berkembang menjadi mastitis klinik atau kronis yang berakibat penyingkiran sapi lebih awal. Melakukan deteksi dini dengan pereaksi terhadapcontoh susu dapat memperkecil resiko tersebut. Ujimastitis subklinis di lapang yang ada sampai saat ini,seperti Calijbrnia Mastitis Test (CMT), masih jarangdilakukan karena harga pereaksinya cukup lnahal dansulit diperoleh di pasaran. Untuk memperoleh suatuteknik yang cepat dan pereaksi untuk uji mastitis subklinis di lapang yang relatif lebih mudah, murah dan bahan-bahannya mudah diperoleh di pasaran, maka dikembangkanlah pereaksi yang diberi nama "IPB- I ". Dari penelitian ini diperoleh data bahwa sensitivitas IPB- I, CMT, Whiteside Test (WST), Aulendorfer Mastitis Probe (AMP) mod- 1 dan AMP mod-2 berturut-turut 0,99; 0,92; 0,94; 0,92 dan 0,94. Sedangkanspesifisitasnya berturut-turut 0,92; 0,37; 0,32; 0,47 dan0,89. Nilai prediksi (predictive valz~e)I PB- I, CMT, WST, AMP mod-1 dan AMP mod-2 berturut-turut 0,95; 0,99; 0,97; 0,99 dan 0,97. Nilai Keterhandalan IPB-I lebih tinggi dibandingkan dengan pereaksi lainnya. Namun nilai prediksi untuk pereaksi masih harus diperbaiki.
