2023-06-30T09:05:24+07:00

The demand for premium beef continues to increase along with changes in the lifestyle of upper middle class, increasing tourists and expatriates from abroad. Local cattle usually cannot produce premium beef, but aging can improve the quality of meat. This study aimed to characterize the physical quality (pH, cooking loss, water holding capacity, and tenderness) of bali beef with different aging times. This study used three types of muscles, which is Longissimus dorsi, Gluteus medius, and Semitendinosus from bali beef aged ± 3 years and body weight of ± 350 kg. Samples were aged at cold temperatures for 1, 21, and 42 days. A completely randomized design with a 3x3x4 factorial was used in this study. Least Square Means test was applied if the data obtained is significantly different. The results showed that the three types of muscle produced relatively the same physical properties, except for cooking loss. The Longissimus dorsi and Semitendinosus muscles were aged for 21 days to show the best results of
meat tenderness.

2023-06-30T09:05:21+07:00

The Super Kampung chicken has a non-uniform coat color, this is related to the genetics of its parents. Genetics has a relationship with aggressiveness and this must be supported by a supportive cage floor. This study aims to examine the effect of the interaction between variations in coat color and different types of cage floors. The experimental material used was 120 DOC which were maintained for 70 days. This study used a completely randomized design (CRD) with a 5x2 factorial pattern with 10 treatments, namely 5 coat colors (W) and 2 cage floors (L), the treatments were repeated 3 times so there were 40 experimental units. The results showed that there was an interaction between the color of the coat and the type of floor of the cage on the pecking order variable. Color variation had a very significant (P<0.01) effect on roaming behavior, but had no significant effect (P>0.05) on pecking order behavior, feed conversion and performance index. The cage floor treatment had no significant effect (P>0.05) on all variables. The conclusion of this research is genetic such as genes (SORCS2) will be related to the level of aggressiveness. So that there are interactions of these two factors to the intensity behavior of pecking and pecking orders.

2023-06-30T09:05:12+07:00

Sentul chicken is one of Indonesia’s native chickens that has high potential for meat and egg production performance. The production of Sentul chicken breeds with high body resistance is one of the solutions to fulfill this potential. This research aimed to ascertain the impact of various IgY concentrations (high, medium, and low) on the production of 90 Debu and 90 Kelabu Sentul chickens. Parameters observed included pre-laying and laying performance. Six replications of a completely randomized design were used to conduct the experiment. The Anova test was used to analyze the data that was collected. The findings revealed that different strains and sex of Debu and Kelabu Sentul chickens did not significantly affect the value of IgY concentration. In the entire population studied, only 12.09% of Debu Sentul chickens and 11. 32% of Kelabu Sentul chickens had low Igy concentration values. In pre-laying period, the difference in the types of chicken strains has no significant effect on the body weight gain and the
feed convertion. Chickens with high IgY concentrations performed worse during the laying phase than hens with low IgY concentrations. The research found that the population of Kelabu Sentul chickens with high IgY concentration value is more than Debu Sentul chickens, which makes them suitable to be used as breeders.

Empowering smallholder cattle farmers through the Field station of School for Smallholder Community (SL-SPR) Program is one of the efforts to improve the reproductive performance of Bali cattle in smallholder farmers. This research aims to evaluate the reproductive performance of Bali cattle reared semi-intensively in SL-SPR Sungai Lilin, South Sumatra. Data on reproductive performance were collected from the observation method through direct observation and interviews with respondents in the community. The respondents was totally 45 smallholder farmers, with a total number of Bali cattle observed of as many as 150 cattle and 372 heads of cow-calf. The data were analyzed using descriptive analysis of variance mixed model using SAS 9.2 software. The results showed that Bali cattle reproductive performances average first calving (AFC) was 971.09 ± 246.47 days. The average calving interval (CI) value was 381.90±72.33 days, while the average days open (DO) value was 111.90±72.33 days. However, the values of AFC, CI and DO had no significant differences (P>0.05) based on differences in season, sex, year of birth, and the interaction between the year of birth, and parity. Bali cattle reproductive performance in SL-SPR Sungai Lilin is in the ideal category.
