Background and Aim: Antibiotics have been used as growth promoters in poultry. However, continuous and long-term antibiotics can cause resistance, suppress the immune system, and accumulate toxic residue. To overcome these problems, feed additives that are safe for livestock and health for humans are needed, including probiotics. Therefore, the study aimed to determine the effect of probiotics (Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus lactis, and Bifidobacterium spp.) and Moringa oleifera extract on performance (body weight gain, body weight, feed intake, feed efficiency, and feed conversion ratio [FCR]), carcass yield (carcass weight and percentage of carcass) and mortality of Peking duck. Materials and Methods: This study used 48 Peking ducks, divided into four treatments and six replications. Each replication consisted of two ducks. The treatments were as follows: T0=control, T1=4 mL containing 1.2×108 CFU/mL of probiotic in drinking water, T2=4 mL containing M. oleifera extract in drinking water, and T3=2 mL containing 1.2×108 CFU/mL of probiotic in drinking water+2 mL containing M. oleifera extract in drinking water. The probiotics consist of L. acidophilus, L. casei, L. lactis, and Bifidobacterium spp. The data were statistically analyzed through analysis of variance. For the follow-up test, a multiple range test was conducted. Results: There was no significant difference (p>0.05) between body weight, feed intake, and mortality treatments. By contrast, control and treatment showed a significant difference (p<0.05) on feed efficiency, FCR, body weight gain, carcass weight, and percentage of carcass weight. Results of body weight gain statistics showed no significant difference (p>0.05) between T0 and T1, but T0 and T1 showed a significant difference with T2 and T3. The results of the feed efficiency statistic showed no significant difference (p>0.05) between T0, T1, and T2, but there was a significant difference between T0, T1, and T3. Feed efficiency at T2 showed no significant difference with T3, T1, and T0. The results of the FCR statistic showed no significant difference (p>0.05) between T0, T1, and T2, but there was a significant difference between T0, T1, and T3. FCR at T2 showed no significant difference with T3, T1, and T0. The carcass weight statistic showed no significant difference (p>0.05) between T0, T1, and T3, but there was a significant difference between T0 and T2. T2 showed no significant difference with T1 and T3. The carcass percentage statistic showed no significant difference (p>0.05) between T0 and T1, but T0 and T1 showed a significant difference (p<0.05) with T2 and T3. Conclusion: Based on the study results, it can be concluded that the use of a combination of probiotics (L. acidophilus, L. casei, L. lactis, and Bifidobacterium spp.) and M. oleifera extract can increase the production performance of Peking ducks and is safe for ducks' health.
The aim of this research was to determine the level of stability of Progesterone-retention time on Eluen Phase Mobile (EPM) solution in storage period for six, eight and 12 hours using High Performance Liquid Chromatography (HPLC). The research method used posttest-only control group design by using three treatments and six repetitions. The three repetitions consist into six hours, eight hours and 12 hours. The data were obtained analyzed by Summery Independent T-Test with SPSS 24 for windows. The results showed that the progesterone treatment in EPM solvents with six-hour storage (P1) and eight hours (P2) retention time progesterone are stable but the progesterone treatment in EPM solvent with 12-hour storage (P3) showed an unstable due to storage time. Besides that there are irrelevant peak which show that many pure molecular fractions are separated in the stationary phase so that the molecular structure of the substance begins to break down. Based on these results, it can be concluded that the storage time of Progesterone in Eluen Phase Mobile began to be unstable at 12 hours of storage.
The purpose of this research was to determine the effect of combination probiotics and Moringa oleifera (M. oleifera) extract in nutrient consumption of ducks. This study used 48 Peking ducks. The concentration of probiotic was 1.2 x 108 CFU/ml. The treatments of this research were P0 (control), P1 (4 ml probiotics), P2 (4 ml M. oleifera extract) and P3 (2 ml probiotics + 2 ml M. oleifera extract). The data were statistically analyzed by Analysis of Variance (ANOVA). The results showed that feed consumption of dry matter, organic matter, crude protein, crude fat, crude fiber and nitrogen free extract were no significant difference (p>0.05) between all treatments. It can be concluded that the addition of combination probiotics and M. oleifera extract can be used to maintain nutrient consumption and safe for health ducks.
The aim of the study was to determine the effect of the use of probiotic lactic acid bacteria (Lactobacillus acidophilus, Lactobacillus casei, Lactococcus lactis, and Bifidobacterium sp) on feed efficiency, carcass weight and carcass percentage in broiler ducks. Probiotics lactic acid bacteria produce bacteriocins and organic acids that inhibit the growth of pathogenic microbes in the digestive tract of poultry, so that the intestinal villi of broiler ducks are healthy. Besides that, probiotics are able to reduce cholesterol levels in meat when consumed by humans and can improve health. This study used 48 peking ducks. The probiotics of Lactic Acid Bacteria used were a concentration of 1.2 x 108 CFU/ml. In this study there were four different treatments, namely P0 (without probiotics), P1 (given 1 ml probiotics/liter drinking water), P2 (given 2 ml probiotics/liter drinking water) and P3 (given 3 ml probiotics/liter of drinking water). The results of the feed efficiency study showed that there was a significant difference (p<0.05) in the P0, P1, P2 and P3 treatments. The highest feed efficiency was at P3 (33.81%) while the lowest was P0 (30.84%). The results of the study on carcass weight indicated that the probiotics tended to be higher than those who were not given probiotics but statistically not significantly different (p>0.05). The highest carcass weight was P3 (1749.92 g) and the lowest was P0 (1709.25 g). The results of the study on the percentage of carcass weight showed a significant difference (p<0.05) in both P0, P1, P2 and P3 treatments. The highest percentage of carcass weight was at P3 (64.60%) and the lowest was P0 (60.96%). It can be concluded that the administration of probiotics lactic acid bacteria (Lactobacillus acidophilus, Lactobacillus casei, Lactococcus lactis, and Bifidobacterium sp) at a dose of 1 ml/liter of drinking water, 2 ml/liter of drinking water and 3 ml/liter of drinking water can affect feed efficiency and the percentage of duck carcasses. but has no effect on the carcass weight of broiler ducks.
