The meat quality of Jawa Super Male Chicken is attributed to the diet treatment offered since the rearing period. This study aimed to evaluate the meat quality of Jawa Super Male Chickens fed on diets made of soybean meal (SBM) fermented with Bacillus subtilis or Aspergillus niger. The experimental groups were control group without steam conditioning or fermentation (P0), SBM fermented with Bacillus subtilis or SBM BS (P1), and SBM fermented with Aspergillus niger or SBM ASP (P2). Ninety chickens aged 21 days (210 ± 3.69 grams) were assigned to three groups, and replicated six times with five birds. Basal diets were made of corn-soybean with 16% crude protein (CP) and 2,950 Kcal metabolic energy (ME). The results showed significant differences (P0.05). The meat pH was within the normal range of 5.90 – 5.93. Conclusively, SBM fermented with Bacillus subtilisor Aspergillus niger increased meat quality.

This study aims to examines composition and essential nutrients of cyanobacterium flour produced from Spirulina (Arthrospira platensis) fermented by yeast on a small scale. During the study, amino acids, volatile organic compounds, SEM (Scanning Electron Microscopy), and proximate composition of fermented and unfermented spirulina were compared. The results showed that fermentation enhanced the levels of total and essential amino acids. This showed that fermentation altered the amino acids and fatty acid profiles, thereby improving the nutritional value of spirulina.

ABSTRACT Bligon goats, as one of the local livestock resources, had significant potential to improved the welfare of coastal communities in Bantul Regency. The aim of the research was to analyzed the contribution of the viability of the bligon goat business in realizing food resilience, livestock empowerment, and the foundations of national resilience in the coastal areas of Bantul Regency. The research was conducted in Bantul Regency at two kapanewons which represent coastal areas, namely Sanden and Srandakan. This study used an approach to economic conditions over the past year. The calculations carried out included total production, added value, the function of livestock as savings, insurances and fertilizer producers. The average age of farmers in the research location was 53 years 10 months, with an average of 13 years of farming experience and an average of 7 goats. The results of calculating the Net Benefit-Cost Ratio (B/C), Payback Period (PP), and Internal Rate of Return (IRR) in calculating the financial feasibility of the Bligon goat farming business in coastal areas showed that this business was worthy of development. The development of Bligon goat cultivation could be used in efforts to alleviated poverty in the community and supported sustainable economic growth in the coastal areas of Bantul Regency. The sustainability of this economic dimension was expected to make a positive contribution to food resilience and national resilience by encouraging an increase in the number of farmers and goats.

Greenhouse gas (GHG) emissions were a major causal factor of global warming that further impacts climate change. This study aimed to inventory the sources of greenhouse gas emissions from the livestock sector in Bangka Belitung. The GHG emissions in the livestock sector was calculated using the Tier-2 method based on guidance from IPCC 2006. Secondary data were collected from multiple sources, including livestock population, enteric CH4 emission factors, and the production and management of local livestock manure. The results of the calculation of GHG emissions in Bangka Belitung from 2018-2022 showed a significant increase from 25.54 to 33.32 Gg CO2 eq, with an accumulation of 139.43 Gg CO2 eq over five years. Beef cattle became the largest contributor to GHG emissions, with enteric fermentation CH4 emissions of 104.34 Gg CO2 eq, accounting for 91.90% of the total CH4 emissions from enteric fermentation sources and 74.84% of the total GHG emissions in Bangka Belitung. The largest contributor to GHG emissions was 78.62% or 109.62 Gg CO2 eq from enteric fermentation sources of ruminants, while N2O emissions from manure management reached 29.10 Gg CO2 eq, and the smallest CH4 emissions were 0.70 Gg CO2 eq, sourced from livestock manure

ABSTRACT: Necrotic enteritis (NE) and coccidiosis are among the most prevalent infectious diseases in broiler chickens, contributing to large profitability losses. Bacillus subtilis is a promising direct-fed probiotic to counter various pathogens infection in broiler chickens. Here, we performed a meta-analysis to investigate the effects of B. subtilis on broiler chickens performance. A total of 28 studies were selected according to a PRISMA checklist. Random-effect model and mixed-effect model of meta-analysis were fitted to estimate the overall effects of B. subtilis (BS) treatment compared to either the control group (CON) or NE-infected group (NEinf) as a baseline. Hedges' g effect size and its variance were used as estimators of standardized mean difference (SMD) calculation where the results were presented at a 95% confidence interval (95% CI) of the SMD. Overall, NEinf broiler chickens depressed (P < 0.01) body weight (BW), average daily gain (ADG), and feed intake, and elevated (P < 0.01) feed conversion ratio (FCR). Treatment with BS improved ADG and final BW of NEinf with no difference (P = 0.15) between BS and antibiotics (AB), indicating that they had comparable efficacy to treat NE in broiler chickens. BS supplemented to uninfected CON (BSS) improved (P < 0.01) final BW, ADG, and FCR. Compared to CON, BS, and AB failed to recover the FCR but these treatments decreased (P < 0.01) FCR when compared to the NEinf group with similar efficacy (P = 0.97). As expected, NEinf birds had a higher mortality rate (P < 0.01) and higher lesion score (P < 0.01) compared to CON, and treatment using AB and BS successfully decreased (P < 0.01) the mortality rate and lesion score. Compared to BS, AB was more effective to lower (P = 0.01) mortality rate, but comparable (P = 0.65) to minimize lesion score. To conclude, B. subtilis could be an effective natural additive to replace in-feed antibiotics in broiler chickens challenged with C. perfringens. However, the efficacy to reduce mortality rate was better with antibiotics treatment.
