Abstract

Tujuan penelitian adalah untuk mengetahui produktivitas kambing Peranakan Etawah (PE) berdasarkan litter size, tipe kelahiran dan mortalitas di Kabupaten Banyumas. Penelitian dilakukan di Pusat Pembibitan Kambing PE Desa Gumelar, Kecamatan Gumelar, Kabupaten Banyumas berupa Kelompok Tani Ternak Kambing Peranakan Etawah Gumelar Banyumas (PEGUMAS). Seluruh anggota kelompok dijadikan responden dengan menerapkan metode sensus. Materi yang digunakan sebanyak 377 ekor kambing PE, terdiri atas 147 ekor induk dan 230 anak kambing (cempe). Variabel yang diamati adalah litter size, tipe kelahiran dan mortalitas. Rata-rata litter size pada saat lahir adalah 1,51 ± 0,43 ekor, dan saat sapih 1,46 ± 0,54 ekor. Litter size cenderung meningkat dari paritas pertama sampai keenam, dengan puncaknya pada litter size keenam yaitu 1,96 ± 0,32 ekor. Tipe kelahiran berpengaruh sangat nyata terhadap produktivitas induk. Produktivitas induk tertinggi pada tipe kelahiran kembar tiga (4,03 ± 0,45). Rataan mortalitas prasapih sebesar 13,48 persen. Kelahiran kembar dua memiliki mortalitas yang lebih tinggi dibandingkan kelahiran tunggal (61,29 vs 38,71%), mortalitas anak kambing betina lebih tinggi dibandingkan dengan jantan (58,06 vs 41,94%).

Abstract

Aims of this research were to know genetic correlation of birth and weaning weight of indigenous sheep. Materials used were 240 birth and weaning weight recorded from 100 days of the indigenous lambs age that were born from 40 dams mated by 8 rams. Nested classification model was used to estimate to genetic correlation. Result of the research showed that the estimated value of genetic correlation from sire, dam, and sire-dam components were 0,32 ± 0,31; 0,52 ± 0,54, and 0,36 ± 0,52, respectively. It could be summarized that genetic correlation between birth and weaning weight of the sheep had a moderate positive. Birth weight characteristic could be used for criteria selection with non-direct selectionmethod for weaning weight.

Abstract

The study was aimed to investigate the antimicrobial activity of bacterial isolates L.plantarum 3CT7 and 20CT8 from goat colostrum. The antimicrobial activity of cell-free supernatant was tested using a well-diffusion method on several indicators: temperature, time of storage, and pH. Antimicrobial activity was recorded in both isolates at pH 2.0; 4.0; 6.0 and 8.0, temperature at 0, 50 and 100 oC, and in cold storage for 0, 15, 30, 45 and 60 days. L.plantarum 7CT3 and L.plantarum 20CT8  have a bigger zone of inhibition than that of Pseudomonas spp. as compared to other bacteria. Testing the cell-free activity was aimed to investigate the metabolite inhibition by L.plantarum. The isolates were capable of inhibiting all pathogenic bacteria in the experiment (S. thypimurium, E. coli, and S. aureus)  as evidenced from the similar zone of inhibition from 15.83 to 16.06 mm. Isolates (L. plantarum 7CT3 dan 20CT8) exhibit inhibitory properties against S.thypimurium, S. aureus, Pseudomonas spp.. and L. monocytogenes at 0, 50 and 100oC. L.plantarum 7CT3 and L.plantarum 20CT8 exhibit antimicrobial activity during cold storage. Both isolates grown in the range of pH from 2 to 8 could inhibit S. thypimurium, E. coli, S. aureus and Pseudomonas spp.  In general, the two isolates are the potential antimicrobial activity with broad ranges of pH, temperature and storage time.

Abstract

The objective of this study was to determine the characteristics and composition of soft cheese manufactured from goat milk, which contained probiotic bacteria, and stored at different temperatures for up to 90 days. Soft cheese was manufactured from fresh Indonesian Etawah goat milk, with a mix starter culture containing Lactobacillus casei and Bifidobacterium longum (1:1). Animal rennet was added to facilitate curding. Fresh cheese produced was wrapped in linen clothes and stored under two different temperature conditions, which were high temperature (H:13-15oC) and low temperature (L: 8-10oC) for up to 90 days.  Results showed that goat cheese was characterized as soft with mild goaty flavor, contained no less than 108 CFU of probiotic lactic acid bacteria, pH of 4.6, 0.5% free fatty acid, 57% moisture, crude 15% crude protein, 22% total fat and 2.5% mineral. Cheese underwent dehydration during storage which caused an increase in the relative proportion of protein, fat and mineral. The evolution of cheese’s pH, titratable acidity and composition was partly affected by storage temperature. At the end of storage periods (90 days) goat cheese was characterized as semi hard and, on average, contained 1.3-1.5% titratable acidity, pH of 4.94-4.95, 31.22-37.06% moisture, 24.59-24.09% crude protein, 33.51-36.17% total fat, and 5.64-5.53% minerals.. Cheese stored at high temperature has slight growth of mold at its surface, which was anormal condition during for cheese ripening. In conclusion, acceptable characteristics and composition of probiotic-containing cheese can be manufactured from milk of Indonesian Etawah goats and stored at temperature of 8-10oC for 90 days.
