Abstract

This study aimed to estimate natural increase (NI), net replacement rate (NRR), output, and population dynamics of Aceh cattle at Livestock Breeding and Forage Center in Indrapuri, Aceh province. Data of population structure, mortality, birth rate, the number of animals entering the herd, and the number of animals released from the herd during 2019were used for determining NIandNRR, and it isusedfor estimation of output. Population structure data (2015-2019) were used to estimate the population dynamics. The results showed that NI was 19.08% (medium category). The availability of replacement stock exceeded the need for replacement (140.08% for male and 73.33% for female); the NRR was 240.08% (male) and 173.33% (female). The output of Aceh cattle was 3.92% (culled male), 5.58% (culled female); the remaining replacement stocks were 5.49% (male) and 4.09% (female) of the total population. The population of Aceh cattle from 2020 to 2024 was expected to increase by 6.02% (65 heads) on average. In conclusion, that BPTU-HPT Indrapuri can be categorized as a beef cattle producing region, but still need efforts to increase natural increase by increasing birth rate minimum 32.77% and reducing mortality maximum 3.0%, in combination with better management systems.

Abstract

This study was aimed to identify genetic diversity in the promoter area and 5' UTR (untranslated region) HSP70 (heat shock protein 70) gene in several beef cattle in Indonesia. A total of 86 blood samples of Bali, Madura, PO (Peranakan Ongole), Limousine, and BB (Belgian Blue) cattle were used in this study. The extracted DNA of all blood samples was then analyzed using the direct sequencing method. The genotyping results showed the presence of five SNP (Single Nucleotide Polymorphism) in the promoter region, namely g.-393T>C, g.-343C>A, g.-202T>C and g.-69T>G and three SNPs at 5' UTR, i.e., g.19A>G, g.45C>T, and g.100_101ins30. The frequency of SNP alleles found in PO, Limousine, and BB cattle was in equilibrium, whereas in Bali and Madura cattle populations, the allele frequency was disequilibrium. In general, the level of diversity of observed alleles ranged from low to high (0.26-1.00), where SNP g.19A>G had the widest variety. It was successfully revealed in this analysis that the SNP g.-69T>G binds to both the NF-Y and CAAT box transcription factor. In addition, the 30 bp (base pair) insertions (g.100_101ins30) that were identified in Bali and Madura cattle have never been reported in previous research studies.

Abstract

The aim of the current research was to analyze the population structure and expression of KISS1 gene associated with reproductive traits through Follicle Stimulating Hormone (FSH) level and DNA sequencing analysis based on KISS1 gene. Genotypes of 23 goat does consist of Kacang goats (n=7), Kejobong goats (n=8) and Senduro goats (n=8) were investigated using DNA sequencing, 16 out of 23 samples were synchronized to examine their FSH level using ELISA method. The data were analyzed using MEGA X software for DNA sequences and General Linier Model (GLM) for FSH plasma level. The phylogenetic tree showed the high homology between Indonesian native goats with other species showing a gene conservatism. A significantly higher FSH plasma levels were obtained from Kacang and Kejobong than Senduro goat (P = 0.002), litter size (LS) 3 than LS 1 (P = 0.0175), further CAATGCGCAACGCT haplotype and GA genotype at g.2459 G>A have a higher FSH plasma than other haplotypes and genotypes (P = 0.0027; P<0.0001) and are associated with high LS (3.0±0.18). Neither sample collection times nor parities have different significantly. The current trial indicated that CAATGCGCAACGCT haplotype and GA genotype at g.2459 G>A were correlated with reproductive traits.

Abstract

The study was aimed to evaluate the effect of age on the serum metabolite of female Brahman crossbred cattle raised extensively under the cattle-oil palm integrated system for 3 months. Thirty calves aged 3-6 months, 30 heifers aged 12-18 months, and 30 cows aged 48 months which were clinically healthy were selected and used in this study. Blood samples were collected from coccygeal vein. The serum was separated by centrifugation and stored at -20oC until the time of analysis. Blood samples were collected from coccygeal vein as much as 4 mL. Serum metabolites were determined using an autoanalyzer (The Roche/Hitachi Cobas 6000 analyzer). Serum concentration of ALB, Ca, P, Na, K, and Cl in calves were higher than heifers and cows (P<0.05), while serum creatinine, total protein, blood urea nitrogen (BUN) and globulin concentration in cows were higher than those ofcalves (P<0.05). Serum glucose concentration in calves and heifer was higher than that in cows (P<0.05). It could be concluded that the age factor must be considered in the interpretation of the results of the examination of the serum metabolites of Brahman crossbred cattle raised extensively in oil palm plantations.

Abstract

The role of modern markets is increasing in the food system in Indonesia, mainly as a result of technological and institutional advances. Indonesian households' food consumption still depends on staple food. The share of household expenditure on meat, eggs, and milk was only 12 percent. The purpose of the study was to analyze the pricing of livestock products in retail level in the modern market.  The data used in this study is daily price data for beef, eggs, and chicken at wholesale and retail levels published through the National Strategic Food Price Information Center (PIHPSN) from January 2020 to December 2020.  This study employed a quantitative method, through the formulation of an econometric model, and applied the 3SLS method to estimate the model.  The results show that traders face an increasing price risk following the Covid-19 pandemic.  The retailers enforce price stabilization at the consumer level when prices at the wholesaler level fluctuate. However, the study did not find the practice of price averaging between commodities at the retailers level.  The results of this study are useful for policy formulations aimed at stabilizing food prices.

Abstract

Ascorbyl-6-palmitate (AP) was a lipid-soluble synthetic ester of ascorbic acid that has been used as a preservation agent for foods and as an antioxidant in cosmetics and related products. This study aims to investigate the effect of shearing management and ascorbyl palmitate administration on physiological and hematological profiles in under heat load Padjadjaran sheep. The physiological profile involves respiration rate (RR), Pulse rate (PR), and rectal temperature (RT). Twenty rams Padjadjaran 1 – 1,5 year-old, weighing between 25 to 47.5 kg used from sheep breeding station Purwakarta, West Java - Indonesia. There are two treatments level in this research, (1). Shearing divide into two groups, unshearing (c0) and shearing (c1); (2). AP administration also divides two groups, not given (a0) and given 400 mg each head daily (a1). The whole treatments were a0c0, a0c1, a1c0 and a1c1. Heat exposure application was exposed to sunlight when the sheep exposed, the animal tethered by rope at the neck region. The sheep exposed to the sun when the ambient temperature at least 34oC, 180 minutes each day, three days a week. The result showed that AP administration and shearing have interaction effects on RR, PR and RT. The level of glucose and total protein is affected by interaction effect of AP administration and shearing, while cholesterol affected to shearing. The conclusion, supplementing AP and shearing application could reduce the negative impact of heat stress on physiological and blood metabolite profiles of Padjadjaran sheep. Although the wool of local breed has not economic value, the shearing is regularly needed.

Abstract

The purpose of the research was to study the effects of dextrin powder with a different concentration on the physical, chemical, and microbiology properties of the product. The research was conducted using a Completely Randomized Design (CRD) with five treatments and four replications, namely the addition of dextrin filler with a concentration of 0% (T0), 2,5% (T1), 5% (T2), 7,5% (T3), and 10% (T4) (w/v). The quality of powdered goat milk kefir that is analyzed are physical, chemical, and microbiology properties. The data were analyzed using SPSS 26.0 application using Analysis of Variance (ANOVA) followed by Duncan Multiple Range Test (DMRT). The test results show a significant difference in dextrin concentration (P<0.05) on solubility, total acid content, yield, water content, protein content, pH, total dissolved solids, carbohydrate, lactic acid bacteria, yeast, and microbe content of the product and shows no significant difference on the viscosity of the product. It can be concluded that the addition of dextrin can increase the yield, solubility, total dissolved solids, water content, carbohydrate, total microbe, lactic acid bacteria, and microbe but also decreased the pH value and the protein content, with the best treatment was the addition of dextrin of 10%.

Abstract

The objectives of this research was to analyze the polymorphisms of SNP g.10428C>T in the SCD gene using PCR-RFLP and its association with meat charactheristics in Bali cattle. The number of 52 Bali cattle from BPTU-HTP Denpasar were used in this study and which were compared to Belgianblue (n=30), Limousine (n=14), Peranakan Ongole (PO) (n=30) and Wagyu (n=7). The polymorphism of the SCD gene was characterized by the use of the PCR-RFLP technique with HinfI enzyme restriction. The characteristics of the meat quality in Bali cattle were estimated using ultrasound imaging method. Genotyphic and allelic frequencies, heterozygosity values, and the Hardy-Weinberg equilibrium have been calculated using PopGen 1.32. The association between genotypes of SNP g.10428C>T SCD gene and meat quality characteristics was calculated using t-test. The results showed that homozygous genotypes (CC and TT) and heterozygous genotypes (CT) of the SCD|HinfI gene with C (0.26) and T (0.74) allele frequencies were and  in Bali cattle. The CC genotype was found in Belgian-blue, Limousine, PO, and Wagyu cattle with the allele C frequency of 1.00. The observed heterozygosity (Ho=0.44) higher than expected heterozygosity (He=0.39) showed high diversity in Bali cattle. Genotypes of SNP g.10428C>T SCD gene were associated with backfat thickness, marbling score, and percentage of intramuscular fat. Thus the SNPs g.10428C>T have potential as marker-assisted selection candidates for Bali cattle.

Abstract

Kalang (KBuf), Krayan (KrBuf), and Thale Noi buffaloes (TBuf) are swamp buffalo genetic resources in Indonesia and Thailand. The maternally inherited mitochondrial DNA (mtDNA), particularly D-loop region is an important material for phylogenetic inference and analyzing genetic diversity. Therefore, the objectives of the present study were to evaluate genetic diversity and to reconstruct the phylogenetic tree within buffalo breeds in Kalimantan, Indonesia, and Phatthalung, Thailand using mtDNA D-loop sequences. A total of one hundred forty buffaloes (70 males and 70 females) were observed including 40 buffaloes from North (NK), 40 from East (EK), and 40 from South Kalimantan (SK) provinces Indonesia and 20 from Phatthalung (PT) province, Thailand. DNA samples were isolated from buffalo tail hairs. DNA sequences were manually assembled using BioEdit program with consideration of gaps and ambiguous sequences. The phylogenetic tree of buffalo was generated by PHYLIP software. The observed variables included haplotype diversity, genetic distance, and genetic tree. The 956 bp of amplified mtDNA D-loop fragment presented a total of 24 haplotypes with several mutations that included transitions (293), transversions (60), deletions (15), and insertions (20). The neighbor-joining tree using the Kimura 2 parameter model demonstrated two local buffalo clusters among buffalo from Kalimantan and Thailand with four buffalo relationship patterns observed from buffaloes in Kalimantan Island (KBuf and KrBuf), Indonesia. The Results of the present study demonstrated that the buffaloes sequence analysis revealed relatively high diversity and is a good basis to perform selection and modern buffalo breeding development.
