Abstract

Indonesian Indigenous poultry originated from the central part of Java Island, called Kedu chick-en, given diet added with inulin of dahlia tuber extract (IDTE) to evaluate body resistance and protein deposition. The experimental animals were 150 birds of 14-day-old Kedu chicken (initial body weight was 148 ± 16.4 g) until 12 weeks old. Dietary treatments were T1: farmer’s diet with protein concen-trate; T2: T1 + 1.2% inulin of IDTE, and T3: modified diet with common protein sources + 1.2% IDTE. A completely randomized design was assigned with 3 treatments (5 replications with 10 birds each). Parameters observed were rate of passage, protein and fiber digestibilites, Nitrogen (N) and Cal-cium (Ca) retentions, body resistance (plasma concentration of corticosterone/CTC, level of immuno-globulin A/IgA, and heterophyl-lymphocyte/H/L ratio), protein metabolism (fecal Nτ–methylhistidine/Nτ–MH and muscle protein mass), feeds consumption, feed conversion ratio (FCR), and body weight gain (BWG). Analysis of variance and Duncan’s test were applied to analyze data. Rate of passage, N and Ca retentions, BWG, IgA level, and muscle protein mass increased; in contrast, FCR, fecal Nτ–MH, and plasma CTC decreased due to the feeding effect of the T3 diet. All parameters, except IgA level, between treatment T1 and T2 indicated similar values. It can be concluded that a modified diet added with IDTE (T3) can modulate the increase in N retention and immune status, with the decrease in muscle protein degradation indicated by low fecal Nτ–MH excretion, and finally, brings about a bet-ter growth rate, with higher muscle protein deposition.

Abstract

A study was conducted to explore the essential mineral concentrations of volcanic soils and forag-es in different eruption-impacted areas and discuss the possible effects on beef cattle nutrition. A total of 75 forage and topsoil samples were collected in the eruption-impacted areas of five active volcanoes located on different islands in Indonesia: Agung Mt. (Bali), Gamalama (North Maluku), Lokon (Noth Sulawesi), Merapi (Central Java), and Sinabung (North Sumatra). The samples were analyzed for the essential macro minerals (Ca, P, Mg, K, Na, S) and trace elements (Fe, Zn, Cu, Mn, Co, Se). Results found that Ca forage varied from 0.52 to 0.76 ppm, P: 0.09-0.36%, Mg: 0.26-0.39%, K:1.55-4.21%, Na: 0.09-0.12%, and S: 0.12-0.65%. The Fe concentration of 109-308 ppm was the most varied trace element in the forages, followed by Mn (30-186 ppm, and Zn (50-85 ppm). The soils Ca, Mg, Na, and S varied from 0.38-0.87, 0.07-0.71, 0.09-0.14, and 0.01-0.07%, respectively. The potential P and Mg ranged from 48.83-174.87 and 23.99-39.97 mg/100 g, respectively. The soil was considerably rich in Fe (142,230-20,252 ppm), followed by Mn (66-180 ppm), Zn (37-56 ppm), and Cu (10-60 ppm). Con-sidering requirements for growing cattle, forage K, S, and Cu exceeded tolerable levels; they were fa-vorable to Ca, Mg, Zn, Co, and Se concentrations, but P and Na were insufficient. In conclusion, the essential minerals most likely to limit beef cattle's nutritional status and productivity in the eruption-impacted areas are K, S, Cu, P, and Na.

Abstract

Crossbreeding between Bali cattle with exotic bulls (such as Simmental and Limousin) has been widely developed in several regions in Indonesia. This study aims to determine changes in exterior characteristics and differences in vital statistics of Bali cattle and their crosses in West Lombok Regen-cy. A total of 91 female cattle aged 1 to 5 years were sampled, consisting of 5 Bali cattle (100%Bali), 54 F1 (50%Bali), 21 G2 (75%Bali/25%Bali), and 11 G3 (12.5%Bali) cattle. Qualitative (color and shape) and quantitative cattle data (vital statistics) were collected through observation and measure-ment. Identification of Bali crossbred cattle genotypes that have different color patterns using molecu-lar markers of the MC1R gene with forward primer MC1R: 5'-GGTGAGTCTCGTGGAGAACG-3' and reverse primer MC1R: 5'-CGTAGAAGATGGAGATGTAGCG-3', at a target DNA sequence size of 308 bp. The dominant color results of Bali cattle showed brick red (60%) and brown (20%), and there was a dark brown and black color change of up to 100% in the crosses. DNA-pool sequencing of 14 samples indicated individual sequence differences, indicated by overlapping nucleotide arrays after the 174 sequence. Furthermore, sequencing of different color representatives from 12 individual sam-ples shows 4 SNPs, namely g.64C>T, g.147C>T, g.159C>T, dan g.235A>C in Bali crossbred cattle. The measurement of chest circumference of Bali cattle, crossbred F1, G2, and G3 aged 3 to 5 years were 151.80±9.60cm, 175.69±12.63 cm, 175.50±11.04cm, and 173.17±15.06cm, respectively.The re-sult indicate the significant differences of body measurement ((P<0.01). In conclusion, the F1 (50%Bali) crossbred produced superior performance. Single nucleotide polymorphism (SNP) can be used as a genetic marker for colour pattern the dark brown-black in crossbred Bali cattle. However, the com-prehenshive study in the future is still needed in the future for cattle crossbred Bali cattle at different generation.

Abstract

The objective of this study was to evaluate the potential of Cassia alata L. leaf extract as an anti-tick agent through molecular docking analysis against the aspartic protease enzyme from Ixodes ricinus (IrCD1). The study aimed to identify natural compounds that could serve as safer alternatives to syn-thetic acaricides for controlling Boophilus microplus, a major ectoparasite affecting cattle.The research utilized an in silico approach, employing molecular docking techniques to assess the binding affinity of 14 secondary metabolites from Cassia alata leaves against IrCD1. The receptor structure (PDB ID: 5N7Q) was obtained from the Protein Data Bank, while ligand structures were sourced from PubChem and KNApSAcK. The docking process was performed using YASARA Structure, with binding free energy (ΔG) and dissociation constant (Kd) values analyzed for ligand-receptor interactions. Addition-ally, the bioavailability of the selected compounds was assessed using Lipinski’s Rule of Five. The results identified four key metabolites—chrobisiamone A, chrysophanol, quercetin, and rhein—as the most promising inhibitors, with binding free energy values lower than the native ligand, pepstatin. Chrobisiamone A demonstrated the strongest interaction with IrCD1, indicating its potential as a potent acaricidal compound. The study also found that these compounds exhibit strong hydrogen bonding and hydrophobic interactions at the receptor’s active site, enhancing their inhibitory potential. In conclu-sion, the findings support the potential development of organic acaricides derived from Cassia alata L. leaves, with chrobisiamone A emerging as a promising candidate. Further in vitro and in vivo studies are needed to validate its efficacy and safety in tick control applications.

Abstract

The present study was undertaken to evaluate the effect of exposure to the slaughter ambient on catecholamines, β-endorphin, plasma enzymes, and apoptotic index and shear-force of Longissimus thoracis et lumborum (LTL) in goats. A total of 18 goats (Boer cross bucks, 1 year age, 27.50 ±1.5 kg live weight) used in the study were divided into three groups viz. goats were slaughtered alone (Control), goats were exposed to psychological stress by exposure to the slaughter ambient (E) and goats were slaughtered in front of E goats (S). The apoptotic index of LTL muscle cells was assessed at pre-rigor state. The dressed carcass was kept in a chiller (4±1°C) for 5 days and shear force values of LTL muscle were assessed on 0-day, 1 day (24 h), and 5-day intervals. The exposure to slaughter am-bient caused a significant (p<0.05) increase in lactate dehydrogenase (LDH), nor-adrenaline, and β-endorphin levels. The apoptotic index of the E samples was recorded as significantly (p<0.05) higher than control and S samples. The apoptotic index of the S samples was significantly (p<0.05) higher than the C samples. As for the shear force, the E samples exhibited lower values (p>0.05) than the C and S samples. Thus, the present study highlights the influence of preslaughter exposure to slaughter ambient on the tenderness of LTL muscle in goats during post-mortem aging.

Abstract

Capripox is a highly infectious, often fatal, illness that results in severe losses; it is caused by Capripoxvirus (CaPVs) of the Poxviridae. It is challenging to distinguish between members of the CaPVs, even if the infection may be diagnosed based on the clinical picture. The objective of the study was to analyze G-protein Coupled Receptor gene identified from Sheep Capripoxvirus in Rafha. Saudi Arabia. Sequence alignment revealed multiple substitutions in the nucleotides and their deduced ami-no acids. Identity of the GPRC gene sequence among local strains was estimated to be 96.7-100%, whereas homology among selected CaPVs was found to be 88.0-100%. Evolutionary divergence anal-ysis showed a discrepancy of 0.0 to 0.03% among local viruses and 0.0 up to 0.94% related to homolo-gous CaPVs included. Phylogeny displayed CaPVs into three groups; local strains scattered into four branches together with other SPPVs from Saudi Arabia, while the second clustered SPPVs from Saudi Arabia, Iraq and Nigeria and the third includes GTPVs and LSDVs. Analysis showed that at least four variants of CaPVs are circulating among sheep in the region. Molecular analysis will help to identify the involved strains to adopt effective preventive measures.
