Probiotic Testing of Lactobacillus brevis and Lactobacillus plantarum from Fermented Cabbage Waste Juice

Objective: The aim of this study was to test the ability of Lactobacillus brevis and Lactobacillus plantarum derived from fermented cabbage waste juice to acts as probiotics. Materials and Methods: Tests of probiotic ability included tests of bile salt resistance and pH resistance and tests of sensitive inhibition of Escherichia coli and Salmonella pullorum growth. Results: Lactobacillus brevis and Lactobacillus plantarum derived from fermented cabbage waste juice were able to grow and develop at pH values from 2.5-5.5 and bile salt concentrations of 1-5%. Lactobacillus brevis was able to strongly inhibit Escherichia coli and Salmonella pullorum growth, while Lactobacillus plantarum showed very potent inhibition of Escherichia coli growth and potent inhibition of Salmonella pullorum growth. Conclusion: Lactobacillus brevis and Lactobacillus plantarum derived from fermented cabbage waste juice are suitable for use as poultry

Protein Binding Capacity of Different Forages Tannin

Eight forages of tannin sources(Leucaena leucocephala, Arachis hypogaea, Mimosa pudica, Morus alba L, Swietenia mahagoni, Manihot esculenta, Gliricidia sepium, and Bauhinia purpurea)were evaluated their tannin content and protein binding capacity. The protein binding capacity of tannin were determined using precipitation of bovine serum albumin (BSA). Swietenia mahagonihas higest total tannin level and condensed tannin (CT) compared with other forages (P<0.01). The Leucaena leucocephala has highest hydrolysable tannin (HT) level (P<0.01). The total and condensed tannin content of Swietenia mahagoni were 11.928?0.04 mg/100 mg and 9.241?0.02mg/100mg dry matter (DM) of leaves. The hydrolysable tannin content of Leucaena leucocephala was 5.338?0.03 mg/100 mg DM of leaves. Binding capacity was highest in Swietenia mahagoni and Leucaena leucocephala compared to the other forages (P<0.01). The optimum binding of BSA to tannin in Leucaena leucocephala and Swietenia mahagoniwere1.181?0.44 and 1.217?0.60mg/mg dry matter of leaves. The present study reports that Swietenia mahagoni has highest of tannin content and Leucaena leucocephala and Swietenia mahagoni capacity of protein binding.

Digestibility of Complete Feed with Addition of Vitamin E in Female Bligon Goat

Twelve female Bligon goats, age 18 m and with body weight of 18.75 ± 2.51 kg, were used in this experiment to determine the effect of vitamin E addition on complete feed digestibility. The animals were placed in individual metabolism cage and divided into three groups, namely, R0, diet without addition of vitamin E as a control (basal diet); R1, basal diet +0.75 g (17 IU) dl-α-tocopherol acetate (vitamin E); and R2, basal diet +1.125 g (20 IU) dl-α-tocopherol acetate (vitamin E). This experiment was performed for 6 weeks of diet adaptation and 12 d of collection period. During collection period, the amount of feed offered, refusal feed, feces, and urine excreted were recorded, and samples were taken for nitrogen analysis. Nitrogen intake, fecal nitrogen excreted, and urinary nitrogen excretion were calculated. The data obtained were analyzed by analysis of variance using one-way completely randomized design followed by Duncan’s multiple range test (DMRT). The result showed that addition of vitamin E increased dry matter (DM), organic matter (OM), ether extract (EE), crude fiber (CF), and nitrogen-free extract (NFE) intake significantly. There were no significant differences of digestibility of dry matter, organic matter, crude fiber, and nitrogen-free extract as an effect of vitamin E addition, while crude protein digestibility increased significantly. It could be concluded that addition of vitamin E to the diets of female Bligon goat at the level of 17 IU was recommended.

Reproductive Performance of Jabres Cow at Brebes, Central Java Province, Indonesia

This study was conducted to observe the reproductive performance of Jabres cow at Brebes Regency, Central Java Province. One hundred and seventy four heads of cows were used in this study. Animals were raised by farmers as usual. Feed consumption was observed for 6 days. Birth weight was weighed soon after calves were born. Weaning age, postpartum estrus, postpartum mating, service per conception, gestation period, and calving interval were investigated based on the farmers’ recording. The data collected was analyzed quantitative description. Dry matter (DM), crude protein, and total digestible nutrient intake of cow were 2.32% BW, 11.41% DM, and 60% DM, respectively. Birth weight of Jabres calf was 18.14 kg ± 1.48 kg. Weaning age, postpartum estrus, postpartum mating, service per conception, gestation period, and calving interval of Jabres cow were 191.72 ± 35.30 days, 83.21 ± 19.05 days, 100.22 ± 22.99 days, 1.71 ± 0.80 days, 280.35 ± 17.52 days, and 383.96 ± 21.11 days, respectively. It is concluded that reproductive performance of Jabres cow is quite good. The calving interval can be improved by shortening PPM and decreasing S/C values.
