INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh suplementasi daun katu terhadap produksi dan komposisi susu kambing Peranakan Ettawa periode awal laktasi. Penelitian dilaksanakan di kandang kelompok peternakan kambing perah yang berlokasi di Dusun Kemirikebo, Girikerto, Turi, Sleman selama 2 bulan mulai tanggal 27 Juni sampai 27 Agustus 2009. Penelitian ini menggunakan 8 ekor kambing PE pada awal laktasi dengan bobot badan 36 sampai dengan 55 kg yang dibagi dalam dua perlakuan dan empat ulangan. Pakan basal yang diberikan 90% hijauan (kaliandara) serta 10% konsentrat (wheat bran). Kelompok ternak yang diujikan adalah kontrol yaitu tanpa suplementasi daun katu dan perlakuan dengan suplementasi daun katu sebanyak 0,06% dari bobot badan. Data dianalisis secara statistik menggunakan metode T-Test. Parameter yang diamati adalah konsumsi pakan, produksi susu, komposisi kolostrum dan komposisi susu kambing. Hasil penelitian menunjukkan bahwa suplementasi daun katu dapat meningkatkan komposisi kolostrum yaitu protein kolostrum kambing Peranakan Ettawa secara nyata namun tidak memberikan pengaruh terhadap konsumsi pakan, produksi susu dan komposisi susu.(Kata kunci: Kambing Peranakan Ettawa, Daun katu, Produksi dan komposisi susu) ABSTRACTThis experiment was aimed to evaluate the effect of katu leaves as feed supplement on milk production and milk composition of Ettawa Crossbred goat during early lactation. The experiment was conducted in the village of Kemiri kebo, Girikerto, Turi, Sleman started from June, 27 until August, 27 2009. The experiment used 8 pregnant goats weighing 36 to 55 kg. The goats were divided into 2 treatments, those were control and treatment groups. The goats in control group received basal feed as much as 10% dry matter of body weight, consisted of calliandra and concentrates with a ratio of 9 to 1 respectively. The treated goats were fed with the same basal feed as those in the control group and supplemented with katu leaves at 0,06% of bodyweight. The examination was conducted to collect data on feed intake, milk production, composition of colostrum and milk. Data were statistically analyzed with T-test. The result showed that katu leaves supplementation as much as 0,06% of body weight was able to increase protein level of colostrum significantly but had no significant effect on feed intake, milk production, and milk composition.(

A definitive diagnosis of M. bovis infection in animals depends on the isolation of the organism, as the optimum condition for the primary isolation of M. bovis infection has not been determined. In this study a total number of 2550 cattle from different governorates in Egypt were tested by Single Intradermal Cervical (SID) tuberculin skin test. Positive reacted cattle (no= 42, 1.6%) were slaughtered and suspected lesions were collected, these samples were decontaminated by using three different methods, which were 0.75 % Hexadecyl Pyridinium Chloride (HPC), 5% oxalic acid and 6 % sulphuric acid. Isolation of mycobacteria from 42 samples by using these decontaminated methods were of 34 (80.9 %), 30 (71.4 %) and 28 (66.6 %), respectively. So it could be concluded that using HPC method as decontaminated agent revealed high rate of isolation of mycobacteria with less contamination (7.1 %) than the other two methods.

Due to direct economic repercussions on livestock and indirect consequences for human health, knowing the prevalence rates of bovine tuberculosis is essential to define an effective control strategy. Our study was performed in 32 dairy cattle farms as we subjected 10800 dairy cattle to the Single Intradermal Comparative Tuberculin skin Test (SICTT). The skin test was interpreted according to guidelines of the World Organization for animal health (OIE). Twenty five farms (78%) have reactors to the SICTT. We also studied the relation between physiological variables with breeds, pregnancy, lactation, size of farms and the other risk factors explained in the study. Out of the 10800 tested animals, 228 (2.1%) were reactors to the skin test. The factors identified as possibly enhancing the risk of bovine tuberculosis (bTB) were herd size, age of animal, farming (housing) conditions. Other factors including breed and physiological status of the animal did not contribute to tuberculin sensitivity. The finding that large size and intensively (often poorly) managed herds were at greater risk of bovine tuberculosis and suggests that significance of bTB is increasing in Egypt parallel to an increase in the dairy operation. This surely indicates that if measures are not taken promptly, the impact of the economy and public health could be enormous. It was concluded that bTB continues to infect animals in Egypt but the prevalence was moderate, nevertheless the continued threat of economic loss in animal industry due to the persistence of bTB that should not be ignored.
