Abstract

A study to compare the back fat thickness, rib eye muscle area, and body condition score (BCS) of young thin-tailed lambs fed various levels of carica Dieng seeds in rations. Eighteen male lambs aged 3-4 months with an initial body weight of 10.68 ± 1.30 kg were applied three feeding treatments (T) following a completely randomized design, T1 = complete feed containing 5% carica seeds, T2 = complete feed containing 12.5% carica seeds, and T3 = complete feed containing 20% carica seeds, with six replications each.  At the end of 14 weeks of feeding treatment, back fat thickness and rib eye muscle area were measured using the Digital Veterinary Ultrasound Imaging System CTS-800. Yield grade value was determined using back fat thickness data, while the BCS assessment was carried out visually. The results showed that various levels of carica seeds addition to complete feed did not produce significant differences (P>0.05) in all variables measured. Back fat thickness, BCS, and rib eye muscle area in young thin-tailed sheep were  1.46 mm, 3.06, and 15.52 cm2, respectively. It might be concluded that supplementation of carica Dieng seeds up to 20% in the complete feed can still be utilized by young thin-tailed sheep.

Abstract

Anaerobic digestion (AD) of dairy cow feces (DCF) has low methane production per ton of waste. A strategy to overcome this drawback is to co-digest DCF and carica seed (CS). Currently, CS is still a waste from the candied carica in the syrup industry and is often just thrown away into the environment. This research aims to evaluate the optimal level of combination for methane production from DCF with co-substrates of germinated (CGM) and non-germinated (CNG) CS meal using Respond Surface Methodology (RSM). This research uses a completely randomized design with a factorial pattern consisting of the first factor being CGM and CNG, and the second factor being the combined level of DCF and CS (CGM or CNG. The result showed that utilization of CS can increase significantly (p<0.05) methane production of the final substrate compared to the control (digester treating DCF only). Utilization of CGM as co-substrate with DCF can also increase methane production (p<0.05) compared to CNG. All parameters in the liquid phase were in the normal range for AD. Based on the research results, the optimum point with a desirability value close to 1 was achieved at a ratio of CGM10 and DCF90. CS was proven can be used as a co-substrate with DCF to increase methane production of the final substrate and germination can be used as a method to increase the methane yield of CS.

Abstract

Feed security is a major challenge in livestock production systems, especially with the limited availability of conventional feed ingredients competing with human food needs and high price volatility. The use of cashew nut shell (CNS) as an alternative feed component can address this challenge. This study adopts a systematic literature review design to identify, analyze, and synthesize empirical research on the utilization of CNS in sheep rations published within the last decade (2016–2025). The aim of this study is to analyze the nutritional potential, biological benefits, as well as the challenges and development opportunities of CNS as sheep feed. The findings show that CNS contains energy levels comparable to conventional feed ingredients, and it also contains bioactive compounds such as anacardic acid and cardol, which act as natural antimicrobial agents and can reduce enteric methane emissions. However, the use of CNS faces challenges related to the presence of toxic phenolic compounds, although these can be mitigated with processing technologies such as fermentation, thermal treatment, and extraction. CNS holds significant potential as an affordable, environmentally friendly, and sustainable alternative feed. Its use contributes to climate change mitigation by reducing methane emissions. This article provides a significant contribution to applied science by offering empirical evidence to support the sustainability of livestock systems through the utilization of alternative feed resources

Abstract

This study aimed to characterize the amino acid profile of the 13 protein-coding genes in the mitochondrial DNA (mtDNA) of Donggala cattle. Genomic DNA was extracted from liver tissue to obtain the complete mitochondrial genome sequence using Next-Generation Sequencing (NGS) technology. The resulting mtDNA sequences were aligned to identify amino acids encoded by the 13 mitochondrial protein-coding genes, namely COX1, COX2, COX3, ATP6, ATP8, ND1, ND2, ND3, ND4, ND4L, ND5, ND6, and CYTB. The results showed that the amino acid profile of the 13 mtDNA protein-coding genes in Donggala cattle was dominated by leucine (Leu), while cysteine (Cys) exhibited the lowest proportion. These findings provide fundamental information on the mitochondrial genetic characteristics of Donggala cattle and may support future studies on the conservation and breeding of local cattle genetic resources.
