African Swine Fever (ASF) is a disease that infects pigs. Common symptoms caused by ASF attacks on pigs are bleeding in the feces and ears as well as sudden weakness of livestock, unable to stand, and death of livestock. ASF virus is not zoonotic so it does not affect human health. This virus has entered Indonesian territory, including the Nias Island, where most of the people cultivate local pigs. The ASF outbreak on local pigs in Nias resulted in the death of many pigs. This paper discusses the spread and death of local pigs due to ASF attacks in Nias. Data compiled from the field and the Animal Husbandry Office in 2020 in the Nias islands, it is known that the pigs that died due to the ASF outbreak reached 120,592 a pigs. Meanwhile, the fact found are that the handling of infected pigs cannot be done optimally, because until now, effective treatment and vaccination for the treatment and prevention of ASF infection has not been found. Therefore, in order to prevent the spread of the plague from becoming more widespread, the current methods that can be applied are the application of biosecurity in the cattle sheds, isolation of infected livestock and the role of the government in regulating the entry and exit route for pigs in the Nias region.
Heat stress in the poor transportation systems will impact the oxidative stress, affecting the quality of chicken meat. The decrease in heat stress levels can be trigerred through antioxidants, one of which is ZnSO4 antioxidants, before cutting. This study aimed to examine the reduction of post-transport stress on the performance of chickens, carcasses, and the physical and chemical qualities of broiler meat treated with ZnSO4. The total broiler chickens transported were 324 roosters aged 4 weeks (with 3 replicates each). All of the transported chickens were treated with ZnSO4 at doses of 0, 80, and 160 ppm for 7 days. Next, the chickens were transported with a travel time of 1, 2, and 3 hours. The breast meats were taken (filet) to be used as research samples. A factorial randomized block design was used as the research design and the data were analyzed using ANOVA (analysis of variance). The results showed that there was no correlation between travel time and the ZnSO4 levels on broiler chicken performance (weight and carcass loss) and physicochemical quality of broiler meat (pH value, percentage of water lost, aw, cooking loss, glycogen content and MDA). Longer travel time significantly reduced live weight, carcass percentage, pH value, glycogen content, while increasing the MDA levels. The addition of ZnSO4 can significantly increase the pH value of breast meat, maintain high glycogen levels, increase carcass percentage, and inhibit MDA formation.
This study was aimed to determine the germination process of seeds with different scarification treatments. This research was conducted at the Laboratory of Animal Nutrition, Faculty of Animal Science, Universitas Gadjah Mada, July 2019. The treatment in this research were different scarification methods of the seeds by sanding (P1), wounding (P2), soaking in H2SO4 (P3), soaking in warm water (P4), and baking at 55º C for 10 minutes (P5). Each treatment using 30 long bean seed that has been repeated for 3 times. Based on the five treatments, the seeds were planted in soil media and their growth observed for 14 days. The results showed that the seed growth for 14 days from the five treatments give an indication that the germination process and the first leaves grow out from long bean seeds was happen in treatment by oven 55º C (P5). Based on these results, it can be concluded that different scarification methods affected on the seed germination process. The fastest seed germination process to produce optimum growth in long bean plants was the scarification treatment by heating the seeds using an oven 55º C for 10 minutes (P5) before the seeds were planted.
Cihateup duck is one of the local Indonesian poultry from West Java. These ducks are raised inTasikmalaya and Garut. Cihateup duck has the potential to produce meat, but duck meat has beenconsidered to have off-odor. components off-odor formed when the fatty acids are oxidized. A studywith the aim to protect unsaturated fatty acids in local duck meat from oxidation using Pluchea indicaLess (beluntas) and Cosmos caudatus (kenikir) in feed as the source of natural antioxidants. The studyused was complete randomized design (RAL) with 7 treatments and 5 replications. The treatment wasPluchea indica Less or Cosmos caudatus powder with the duration of administration 1, 2 or 3 weeksbefore the age of harvest (10 weeks). Ducks used were 35 heads of Cihateup duck. Variables observedwere moisture content, fat content, Malondialdehyde (MDA), composition of fatty acid, and sensorycharacteristic of duck meat. The results showed that the effect of Pluchea indica Less or Cosmos caudatuswere not significant on moisture content and fat content. The effect of Pluchea indica Less or Cosmoscaudatus on MDA, composition of fatty acid, and and off-odor intensities of duck meat during cookingwas significantly different (P<0.05). It was concluded that this addition of Pluchea indica Less for 3 weeksor Cosmos caudatus for 2 weeks could lower off-odor on local duck meat.
The present study aimed to determine the effect of cherry leaf extract (Muntingia calabura L) on hatchability of Balitnak Superior Free Range Chickens (KUB) through artificial hatching. The doses of cherry leaf extract used in this study were 0%, 10%, 15% and 20%. The hatching eggs used came from KUB hens that were intensively reared in the poultry house at UPBS BPTP, North Sumatra. The procedures applied in this study were collection of hatching eggs, fumigation of machines and equipment, setting of machines and hatching eggs, egg washing with cherry leaf extract and hatching of eggs for 21 days. During the hatching process, observations were made on predetermined variables. The observed variables were egg shape index, egg weight loss, shell temperature and hatchability. The method used was completely randomized design (CRD) with 4 treatments and 100 replications. The results showed that the hatching egg shape index in this study was 75,77 – 77,05%. The lowest egg weight loss was at P0 (0%), while the largest weight loss was at P2 (15%). The highest hatchability was observed in P1 (10%) at 84%. The most effective P1 treatment resulted in the highest egg hatchability in the present study.
