Abstract

The aim of this study was to evaluate the effect of different IgY concentrations on the production, reproduction and immunity of Sentul chicken. This research used 20 month-old Sentul chickens which consisting of 10 chickens with high IgY concentration and 10 chickens with low IgY concentration Parameters observed included prelayer performance (feed consumption, weight gain, feed conversion, morbidity and mortality), layer performance (feed consumption, egg production, egg weight, feed conversion, hatchability, morbidity and mortality), and immunity at chicks (IgY concentration of eggs and chicks serum). The experiment was conducted as a completely randomized design. The treatments were high and low IgY concentration. All treatments were repeated 10 times. The data obtained were analyzed using the SAS program t-test. Morbidity and mortality were analyzed descriptively. The results of this research indicated that the prelayer period, chickens with high IgY concentration had a higher performance than chicken with low IgY concentration. This is caused by about 30% chickens with low IgY were in sick condition for approximately seven days. Further, the layer period showed that the chickens with high IgY concentration had lower production performance than the chicken with low IgY concentration. The study concluded that chickens at low IgY concentrations are susceptible to exposure to antigens that lead to decreased productivity. In normal conditions hens, Sentul with high IgY concentration resulted in low production. The observation of chicken immunity showed that concentration of IgY from chicks and eggs did not differ between hens with high IgY concentrations and hens with low IgY concentrations.

Abstract

The purpose of this research was to analysis the value of repeatability and correlation among the traits affecting the production of frozen semen from Holstein’s bull in Indonesia. Repeatability and correlation were calculated based on the data of frozen semen production of 15.699 records from 44 Holstein bulls at Singosari Artificial Insemination Center (SAIC) and 8.935 records from 39 Holstein bulls at Lembang Artificial Insemination Center (LAIC). Repeatability for volume, motility, fresh semen concentration and frozen semen production was evaluated by intraclass correlation method. The repeatability values of LAIC for volume, motility, fresh semen concentration and frozen semen production were 0.60; 0.54; 0.37 and 0.47. The repeatability values of SAIC for volume, motility, fresh semen concentration and frozen semen production were 0.54; 0.30; 0.43 and 0.29. The linear correlation value between volume, motility and fresh semen concentration with the amount of semen produced per collections were 0.41, 0.36, and 0.58. Concentration was the most factors influencing the number of frozen semen produced. The effectiveness of the selection of Holstein's frozen semen producing could be determined by the value of repeatability and the phenotypic correlation among semen quality traits such as volume, motility, concentration and frozen semen production.

Abstract

Contamination that decreased chicken meat quality could be prevented using natural preservatives. Bay leaves (Syzygium polyanthum) contain volatile fatty acids, tannin, and flavonoid that possess bacteriological and fungicidal activity as well as preventing bacterial spore growth. The purpose of this study was to determine the effect of fresh bay leaf infusion on microbiological, chemical, and physical qualities of chicken meat. This study used bay leaves, water, chicken meat, eight strain of bacteria, chemicals and materials for the analysis of chicken meat. The experiment consisted of two steps, the first was the antibacterial properties of bay leaves and the second was the application of bay leaf infusion for chicken meat. Eight bacteria was used for the bacterial inhibition of bay leaf at the concentration of 0, 5, 10, 15 and 20%. The experiment on antibacterial properties of bay leaf (Syzygium polyanthum) used one way randomized design with five concentration treatments, while the application of bay leaf infusions on chicken meat using factorial completely randomized design 2x5 (2 types of soaking and 5 observation time). At the second step, chicken meat was divided into 2 groups, the first group was soaked in water only and the second group was soaked in 15% bay leaf infusion. They were then stored for 0 (control), 2, 4, 6, and 8 hours at the room temperature. Each treatment was repeated four times. The microbiological, chemical, physical qualities of chicken meat were observed. The results showed that bay leaf infusion had the ability to inhibit the growth of bacteria (P<0.05). The highest growth inhibition was found on Leuconostoc mesenteroides, whereas the lowest growth inhibition was on Pseudomonas putida. Bay leaf infusion influenced the number of bacteria in chicken meat. The concentration of 15% bay leaf infusion could decrease bacterial number amounting to 1 log CFU/mL compared to control. The number of bacteria of chicken meat stored significantly increased during the storage (P<0.05). However, the number of bacteria of chicken meat soaked in bay leaf infusion was significantly lower than the control. Bay leaf infusion has no significant effect on the chemical quality of chicken meat but it did on the physical quality of chicken meat. The conclusion of the study was bay leaf infusion could inhibit the bacterial growth and reduced the amount of bacteria in chicken meat, whereas storage time influenced the microbiological and physical qualities of chicken meat.

Abstract

The objective of this study was to determine the activity and the stability of bacteriocin from lactic acid bacteria (BAL) isolated from rumen fluid of thin-tail sheep under the temperature (80, 100, and 121°C), pH (3, 7, and 10), and the length of storage (for 2 weeks under the temperature -8, 11, and 29°C). Lactic acid bacteria obtained by isolation, selection, and identification of thin-tailed sheep rumen fluid were used for bacteriocin production. The crude bacteriocin was partially purified using 70% ammonium sulfate, then was dialysis for 12 hours. The obtained bacteriocin then tested its inhibitory activity against E.coli (representing Gram-negative) and S. aureus (representing Gram-positive) under temperature (80, 100, and 121°C), pH (3, 7, and 10), and the length of storage (for 2 weeks under the temperature -8, 11, and 29°C). The data of bacteriocin activity based on pH, temperature, and the length of storage were analyzed with factorial, then when there was a significant difference of variable because treatment was continued with Duncan's Multiple Range Test (DMRT) test. The results showed that the bacteriocin activity of the three types of BAL against S.aureus is greater than E.coli. The highest activity was shown in pH 3, while the lowest activity was shown at pH 10 (P<0.01). The highest activity was shown at a heating temperature of 100°C, while the lowest activity was shown at a heating temperature of 80°C (P<0.01). The activity of bacteriocin produced by BAL 0 A, BAL 1 A, and BAL 4 C tended to be stable to the heating temperature of 80, 100, and 121°C but decreased with increasing pH value (pH 3, 7, and 10). The best of bacteriocin activity was found at pH 3 (acid), heating at 100°C, and stored at -8°C for 14 days.

Abstract

The aim of this study was to evaluate the effect of different IgY concentrations on the quality of semen (macroscopic and microscopic) and testicular morphometry (weight, length and width of the testes) of Sentul cock testis and its ability to fertilize hens. This study used 4 months of 20 Sentul cocks consisting 10 high IgY concentration cocks and low IgY concentration cocks. This study used a complete randomized design (RAL) with 2 treatments namely low and high IgY concentration and10 times repetitions. Data were analyzed using t-test minitab program versions 16. Based on the result, different IgY concentrations did not affect the quality of semen and testicular morphometrics, but high IgY concentration cocks were able to fertilize more hens than the low IgY concentrations one by using dilution methods. This proves that high IgY concentration cocks are more effective and efficient cocks or stud.
