Performance and Quality of Broiler Meat During Transportation with Various Durations and ZnSO4 level
Get PDFHeat 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

Preference of Goat Farmers to Agricultural Extension as a Source of Information and Knowledge in Banjarnegara Regency
Get PDFIncreasing knowledge of farming is essential in increasing goat production in the rural areas of Banjarnegara Regency. Increased knowledge come from many sources, such as extension and non-extension services (other farmers, books, and other government officials). Systematic efforts continue to increase agricultural extension workers' role in providing information and knowledge to goat farmers. This study aims to identify farmers' preference for the agricultural extension as a source of knowledge and analyze the factors that influence the selection of sources of information and knowledge. One hundred sixty goat farmers in Banjarnegara Regency were selected as respondents using a multistage sampling method. The data collected were analyzed using descriptive statistics and logistic regression. The analysis results showed that most of the goat farmers in Banjarnegara Regency (74.37 percent) preferred obtaining knowledge from non-extension sources. In other words, only a small proportion of goat farmers (25.63 percent) prefer to get information and knowledge from agricultural extension workers. Based on the logistic regression analysis, it was found that goat farmers' education and age of farmers were essential factors (P<0.05) in making decisions related to source in obtaining knowledge on raising goats from the agricultural extension or non-agricultural extension workers. Goat farmers in Banjarnegara Regency who have lower education prefer to get information related to goat farming from non-agricultural extension workers. Meanwhile, younger goat farmers tend to get information from non-agricultural extension workers. Therefore, agricultural extension workers have a more strategic role for goat farmers who have higher education and are more mature with adequate goat farming knowledge

Get PDF The purpose of this study was to determine the effect of gamma-ray irradiation on Sorghum sudanense in the first offspring (F1) on plant growth, production, and lignin content at different harvest ages. This study used a split-plot design in which varieties of Sorghum sudanense with gamma irradiation and Sorghum sudanense without gamma irradiation are the main plot. Meanwhile, the harvest age is the subplot. The planting area was 1.5x1.5 m, each with 3 replications. The materials used were Sorghum sudanense without gamma-ray irradiation and the first generation seeds (F1) of Sorghum sudanense with gamma irradiation. The method used was irradiating Sorghum sudanense seeds with gamma-ray with a dose of 300 Gy, planting, maintenance, and harvesting. The harvest ages were 50, 70, and 90 days. The data observed were plant growth, namely plant height and length, dry matter (DM) and organic matter (OM) production, and lignin content. Sorghum sudanense with gamma irradiation had higher plant height, plant length, also DM, and OM production (P<0.05) than Sorghum sudanense without gamma irradiation. The lignin content of Sorghum sudanense with gamma irradiation was lower (P<0.05) than Sorghum sudanense without gamma irradiation. Longer harvest age increased (P<0.05) plant height, plant length, production, and lignin content. In conclusion, there were characteristics differences between Sorghum sudanense with gamma irradiation and without gamma irradiation (parents). The longer harvest led to higher plant height, length, production, and lignin content. There was an interaction (P<0.05) between varieties and harvest ages. Gamma irradiated Sorghum sudanense had a peak production at the age of 70 days, with a lignin content of 3.63%
