Identification of Gene Diversity of Melanocortin 4 Receptor for Commercial Rabbit Breeds
Full text linkMolecular genetic markers are regularly implemented in rabbit management for better breeding by selecting for specific genotypes. This study aimed to examine the diversity of the melanocortin-4 receptor gene in rabbits in Central Java, Indonesia. A total of 35 bucks were used in this study, comprising 10 New Zealand White, 11 Hyla and 14 Hycole. The DNA was extracted by Gene JET Whole Blood Genomic DNA extraction kit. Single Nucleotide Polymorphism (SNP) was detected by Polymerase Chain Reaction (PCR) and DNA sequencing. Hot carcass weight, cold carcass weight, reference weight and cut point 1-5 weight were among the parameters that were measured. This study showed that Melanocortin 4 Receptor (MC4R) genes were polymorphic, containing missense mutations and one SNP at 519G→A SNP 519GA had two alleles, A and G, with three genotypes (AA, GG, and AG). The rabbit population did not achieve HardyWeinberg Equilibrium (HWE) and showed a low level of genetic diversity as indicated by the heterozygosity results. The result of this study concluded that the frecuency AG as a genotype was higher than either GG or AA and A had a higher allele frequency than G. We recommended improving the validity of the data across various rabbit population

This can be seen from the Domestic Resource Cost Ratio (DRC) svalue of 0.59 and Private Cost Ratio (PCR) of 0.81. Government policies on outputs and inputs of beef cattle business in East Kolaka District reduce incentives for producers, are ineffective in protecting production and cause higher production costs compared to potential profits without these policie
Effects of Seaweed and Organic Mineral Supplementation on Nutrient Digestibility and Milk Yield in Lactating Saanen Crossbred Goats
No full textDairy goat productivity in Indonesia remains relatively low, primarily due to its suboptimal feed efficiency, affecting nutrient digestibility and milk yield. This study aimed to evaluate the effects of seaweed and organic mineral supplementation on feed intake, nutrient digestibility, and milk production performance in dairy goats. An in vivo experimental study was conducted using a completely randomized design involving 16 pregnant Saanen-Etawah crossbred ewes in their second lactation and offered treatment feeds for 4 weeks before parturition until 8 weeks postpartum. The animals divided into four dietary treatments: T0 (control diet without supplementation), T1 (control diet + rumensin), T2 (control diet + 2% seaweed), and T3 (T2 + organic minerals including Cr, Se, and Zn) with the feed offered was based on dry matter requirements of 4% of body weight, once daily at 1.30 p.m. The control diet is a mixture of concentrate, tofu dregs, and forage. The observed parameters included dry matter intake (DMI), organic matter intake (OMI), digestibility of dry matter, organic matter, crude fiber, and crude protein, as well as daily milk yield and its components. The results indicated that while feed intake did not differ significantly among treatments, the supplementation of seaweed and organic minerals significantly improved nutrient digestibility, daily milk yield, and the composition of milk, including fat, protein, lactose, and total solids. The T3 treatment yielded the most optimal outcomes in enhancing feed conversion efficiency and milk performance. These results suggest that seaweed and organic minerals may serve as effective and applicable functional feed additives to sustainably improve dairy goat productivity through optimized rumen function and metabolic utilization

A total of 6 KUB males were selected for the experiment and each of them was subjected to 5 collections of semen. The experiment was performed using a Randomized Block Design (RBD) with 4 treatments. These treatments included P0 (100% Ringer lacate-egg yolk without carrot extract), P1 (80% Ringer lacate-egg yolk + 20% carrot extract), P2 (60% Ringer lacate-egg yolk + 40% carrot extract), P3 (Ringer lactate yolk 40% + 60% carrot extract). The research variables consisted of motility, viability, abnormalities of spermatozoa, and plasma membrane integrity. Data were analyzed using Analysis of Variance (ANOVA) followed by Duncan's test. It was discovered that the percentage of motility and viability up to 48 hours of storage showed significant differences (p0.05) at 48 hours of storage. Furthermore, plasma membrane integrity failed to show a significant difference between groups at 1 hour of storage and was significantly different (p<0.05) at 24 and 48 hours of storage. The best or the highest result is in the P2 group, with plasma membrane integrity being 71.89 ± 2.40%. It was concluded that the use of 40% carrot extract supplementation in Ringer lacate-egg yolk diluent tends to maintain the quality of KUB chicken semen in cold storage for up to 48 hours and was suitable for the application of artificial insemination
Effects of Dietary Plant-Derived Anti-Coccidia on the Production Performance and Oocyst Output of Broiler Chickens
Full text linkAdding feed additives to combat coccidiosis, such as anti-coccidial drugs to broiler diets, can lead to side effects, meat residues, and antimicrobial resistance issues. Alternatively, plant-derived anti-coccidia could serve as safe and simple alternatives compared to synthetic/chemical feed additives. The objective of this study was to evaluate the production performance and oocyst output of broilers fed diets with plant-derived anti coccidia. A total of 300 day-old Cobb 500 broiler chicks were randomly assigned in 30 cages in a completely randomized design with 3 treatment groups, 10 replicates per treatment of 10 chicks per cage. The treatment diets were fed for 35 days: basal diet without anti-coccidia (T1), 500ppm synthetic anti-coccidia containing Narasin and Nicarbazin (T2), and 500ppm plant-derived anti-coccidia containing Cinnamomum camphora, Elephatopus scaber, and Valeriana walichii (T3). Results showed significant differences (p<0.05) in the average body weight gain, feed intake, feed efficiency, and income over feed and chick cost among the three treatment groups. Fecal analysis results showed the absence of oocysts in those feeds with synthetic anti-coccidia and plant derived anti-coccidia. T3 that contains plant-derived anti-coccidia has the highest growth performance among other treatments. In conclusion, plant-derived anti coccidia can be used as an alternative anti-coccidial drug without compromising the growth performance of broiler chicken
Determinant Factors of People’s Business Credit (KUR) Repayment in The Livestock Sector
No full textThe People's Business Credit (KUR) program plays a crucial role in supporting Indonesia's livestock sector, which remains a primary source of livelihood for many rural households. This study aims to identify the characteristics of livestock farmers receiving KUR and the factors influencing loan repayment. Data were collected through a survey of 505 livestock farmers in Purbalingga Regency who had received KUR financing. A binary logistic regression model was used to analyze the determinants of loan repayment. The results show that borrower age, loan amount, loan term, and credit risk score significantly affect loan repayment performance. In contrast, gender, number of dependents, education level, business experience, income, and repayment capacity do not have a significant effect. The findings suggest that borrower characteristics and loan terms are crucial in determining repayment outcomes. Policymakers are advised to align KUR loan terms with livestock production cycles and provide financial literacy support to improve repayment rates and ensure the long-term sustainability of livestock-based KUR programs
