No full textFeed additives is important to improve the appearance of duck production. The purpose of this study was to determine the weight and proportion of Mojosari Laying Duck carcass parts that contained calcium phytobiotics. Twenty-four flocks of 120 mojosari laying ducks (24-week-old) were used. Variation Analysis was used to statistically examine the data (ANOVA). Duncan's Multiple Distance Test is used if the study's data show a substantial difference between treatments. A Complete Randomized Design is employed using 6 treatments and 4 tests, each containing 5 mojosari laying ducks. Treatment (P0) is the control feed, (P1) is the control feed plus zinc bacitracin, (P2) is the control feed plus phytobiotics 0.25%, (P3) is the control feed plus phytobiotics 0.50%, (P4) is the control feed plus phytobiotics 0.75%, and (P5) is the control feed plus 1% phytobiotics. The findings demonstrated that the addition of phytobiotic calcium did not significantly affect carcass weight or the percentage of carcass parts (P>0.05). However, (P2) increased the carcass weight compared to the control meal. Weight of the carcass produced is 792.50±91.06 – 972.50±86.84. The percentage of carcasses is 50±0.05 - 57±0.07. The percentage of back pieces was 32.19±1.54 – 36.32±2.94. The percentage of chest pieces was 7.26±0.84 – 8.63±0.97. The percentage of wing pieces was 14.46±0.48 – 13.63±1.93. The percentage of upper thigh pieces produced was 9.50±0.82 – 10.35±2.31, and the percentage of lower thigh pieces was 11.48±0.91 – 13.34±1.97. Results showed that the addition of phytobiotic calcium did not significantly affect the proportion of parts and carcass weight (P>0.05)

No full textAbstract
Staphylococcus aureus (S. aureus) is a pathogenic bacterium with many virulence factors, such as toxins, immunomodulatory factors, and exoenzymes. Hemolysin is one of the essential toxins in the pathogenesis of S. aureus, with the action of lysing erythrocytes and other cells. This study aimed to determine the phenotypic and genotypic characteristics of S. aureus isolates from animal origin. Eight S. aureus isolates from goat mastitis and raw chicken meat phenotypically evaluated the ability to hemolyze sheep blood. At the same time, genotypic were determinated by detecting the hla and hlb genes. The results showed that most 87.5% (7/8) of S. aureus isolates had β-hemolysis phenotypic. PCR determination showed that all (8/8) isolates were positive for the α-toxin (hla) encoding gene, while half (4/8) of the isolates were positive for the β-toxin (hlb) encoding gene. The use of 5% defibrinated sheep blood agar plates is recommended to determine the hemolytic character of S. aureus tested.

Full text linkAbstract
The large component of feed costs in the production cost of laying ducks requires farmers to use the cheaper feed ingredients but can still meet nutritional needs and maintain good production performance of alabio laying ducks. This study aims to determine the effect of the use of duckweeds in diets on the production performance of alabio ducks including egg production, feed consumption, feed conversion, income over feed-cost, egg weight, yolk-color, and cholesterol levels in duck eggs.The study used a Completely Randomized Design (CRD) method with four treatments and five replications, each of which consisted of three Alabio laying ducks. The research treatments were P0 = 0% the use of duck weed, P1 = 10% the use of duck weed int, P2 = 20% the use of duck weed, and P3 = 30% the use of duck weed for every of the diet treatment. The results showed that the use of duck weeds (Lemna minor) up to 30% in the feed diet had no effect on the amount of egg production, percentage of egg production, feed conversion, egg weight, and IOFC values but it affected the feed consumption, yolk color and cholesterol content of alabio duck eggs. The feed consumptions were not different from the control diet until 20% use of duck weeds, but decreased at 30% due to increased crude fiber feed. The Yolk color scores increased and the egg cholesterol content decreased with increasing use of duck weeds in feed diets. Duck weed has a great opportunity to be used as a source of protein feed.
