Abstract

The livestock sub-sector, an integral part of the agricultural sector, is the animal protein producing sub-sector which plays an important role in meeting people's nutritional needs. The development of the laying hen farming business has enormous potential, this is because purebred chicken eggs contribute quite a lot to animal protein self-sufficiency. The research aims to analyze the input factors of the production that affect the production of layer farming businesses and to assess the production elasticity of these businesses during the COVID-19 pandemic in Blitar District. Data collection took place between July and August 2020 in the Blitar Distrcit. Utilizing a sample random sampling method. The study involved 64 farmers as representative. The research variables used in this study were the population of laying hens, the price of chicken eggs, feed costs, vaccines and medicines expenses, seed prices, mortality, electricity costs, the price of culled chickens, Hen Day Production (HDP) and the number of workers. Quantitative analysis was employed to analyze production costs, revenues, and income, while qualitative analysis was used to analyze production elasticity through Cobb-Douglas regression analysis. The research data were processed using SPSS version 24. The results of the study indicate that 1) the population of laying hens and HDP significantly affected the production of layer farming businesses, along with the cost of vaccines and medications in the Blitar District. 2) The population of layers, mortality rates, electricity costs, HDP, and total labor demonstrated elasticity with respect to the production of layer farms. Conversely, egg prices, feed costs, vaccination and medication expenses, day-old chick (DOC) costs, and final chicken prices exhibited inelasticity concerning the production of layer farms in Blitar district.

Abstract

In Indonesia, small-scale dairy cattle farming dominates, constituting 80% of the industry, with economic pursuits secondary to subsistence needs. Challenges include limited green fodder, declining farmers, low milk quality, diseases, and inadequate infrastructure. Despite these issues, dairy farming persists, particularly in East Java's Malang Regency, a major contributor to national dairy cattle population and milk production. The significance of Pujon Sub-District comes to the forefront, housing the Sinau Andandani Ekonomi (SAE) Pujon Cooperative established in 1975. This cooperative plays a pivotal role in supporting small-scale farmers in Pujon, actively addressing challenges through collaborative efforts. This cooperative facilitates small-scale farmers in Pujon, addressing challenges through collective efforts. In such systems, family labor, including women and children, is integral due to limited availability. The study aims to analyse the income of dairy cattle farmers and their labour allocation as the members of SAE Pujon Cooperative, Pujon District, Regency of Malang. The data of the farm management parameters were collected through a survey at the study area. The results indicate that the average income of the farmers is IDR 4,306,798 per month. Regarding labour allocations, wives work to household affairs and husbands focus more on farming activities. The research concludes that the income of dairy farmers and their labour allocation are related to the farm scale.

Abstract

The micromolar calcium-activated neutral protease 1 (CAPN1) gene encodes the u-calpain enzyme, which plays a crucial role in meat tenderisation. Genetic diversity within the CAPN1 gene, specifically a nucleotide substitution from G to C in exon nine resulting in a change from glycine to alanine at position 316 (CAPN1-316 marker), is known to significantly affect meat tenderness. This study aimed to assess the polymorphism of the CAPN1-316 locus in Bali and Sumbawa cattle. A total of 293 blood samples, 193 from Bali cattle and 100 from Sumbawa cattle were extracted and genotyped using PCR-RFLP with BtgI restriction enzyme (recognition sequence: 5'-C*CRYGG-3') applied to 706 bp PCR products. The results showed the presence of only one genotype (GG genotype) and one allele (G allele) in all DNA samples obtained from the Bali and Sumbawa cattle populations studied. In conclusion, the CAPN1-316 genetic marker showed a lack of diversity or monomorphism in Bali and Sumbawa cattle, making it unsuitable for further association studies in these breeds. Consequently, the CG/AG haplotype identified in Sumbawa cattle warrants further investigation and could serve as an alternative genetic marker, especially due to its monomorphism at the CAPN1-316 locus.

Abstract

Tomato peel is an industrial waste product from tomato vegetables that has not been utilized properly. Industrial waste that has not been utilized will harm the environment. Tomato peel is a source of natural food coloring, antioxidants, and a source of fiber. Application of tomato peel can be added to mayonnaise products to improve the color of low-fat mayonnaise. This study aimed to investigate the effect of giving tomato peel nanopowder as a natural coloring in low-fat mayonnaise based on pH, total acid, protein content, carbohydrates, color, and sensory quality. Low-fat mayonnaise was prepared using sunflower oil, vinegar, and egg yolks by giving the tomato peel nanopowder treatment of 0, 1, 2, and 3% which was repeated 5 times. Analysis of variance (ANOVA) was used as data analysis if there were differences in effect between the treatments, followed by Duncan's Multiple Range Test (DMRT). The research results of adding tomato peel nanopowder with different percentages had a very significant effect (p<0.01) on pH, total acid, protein content, carbohydrates, color, and sensory quality. This research concludes that 3% tomato peel nanopowder applied to low-fat mayonnaise can improve pH, total acid, protein content, carbohydrate, L, a*, b*, and sensory quality.

Abstract

Dairy products from wild horses in Sumbawa Island, Indonesia, are promising to be developed as a probiotic source due to naturally occurring lactic acid bacteria. However, it is less favored due to its pronounced horse flavor. The development of products can beaccomplished by converting them into a probiotic drink and blending them with other ingredients to create a product with enhanced nutritional and sensory characteristics. This research aims to formulate probiotic drinks by blending wild horse milk and modified banana flour (MBF), evaluating their physicochemical and microbiological attributes and sensory quality. A one-factor, Completely Randomized Design (CRD) experimental design was employed in this research. The treatment involved the addition of MBF at three specific concentrations: 0%, 5%, and 10%. The results revealed that the addition of MBF led to significant differences (p<0.05) in the physicochemical properties (pH, viscosity, total dissolved solids, and syneresis). All formulations exceeded the minimum Lactic Acid Bacteria (LAB) requirements set by the Indonesian National Standard (SNI) 2981:2009, ranging from 1.57x109 to 2.35x109 CFU.mL-1. According to the sensory evaluation, probiotic drinks containing 5% MBF exhibited the highest sensory quality, stimulating appetite with dominant attributes such as a brownish-white color, sour taste, minimal skunky flavor, and a slightly sandy/coarse fiber texture. In conclusion, adding MBF enhanced the probiotic drinks' physicochemical properties, total LAB content, and sensory quality

Abstract

This study aimed to assess the impact of dietary energy and protein balance on carcass weight and percentage during the initial growth phase of local chickens, utilizing a meta-analysis approach. The analysis involved integrating data from 11 articles comprising a total of 120 data points. These articles provided insights into the influence of energy and protein-balanced diets on breast and wing percentages in local chickens. The meta-analysis process involved data collection from diverse scientific publications, standardizing units, and tabulating the information in a Microsoft Excel database. Subsequently, SAS was employed to analyse the tabulated data. The findings revealed that a minimum breast percentage of 30.11% required 18.18% protein, and the associated metabolizable energy requirement was 2974.17 kcal/kg. In summary, achieving a minimum wing percentage of 14.19% necessitated 17.81% dietary proteins and 2943 kcal/kg metabolizable energy for a 14.08% wing percentage.

Abstract

The Kuantan cattle, recognized as one of Indonesia's local breeds according to the Indonesian Ministry of Agriculture's Decree Number 1052/Kpts/SR.120/10/2014, were the focus of this study. The objective was to characterize morphometric features, estimate the body weight of Kuantan cattle through regression analysis based on body measurements, and compare the results with the School formula. The research was conducted in Pekanbaru and Kuantan Singingi Regency, using Kuantan cattle from Kuantan Singingi Regency (n=180) and UPT Pasir Putih, Dinas Peternakan dan Kesehatan Hewan, Riau Province (n=30). Morphometric parameters, including wither height, body length, and chest girth, were observed. Descriptive statistics (mean, standard deviation, and coefficient of variation) were used for data analysis. Regression equations were analyzed using SPSS 27. The findings indicated no significant morphometric differences between male and female Kuantan cattle. The body weight of Kuantan cattle could be predicted using single and combined body measurements as predictors. Chest girth (CG) emerged as the best predictor in the regression equation for single body measurement, with the highest values of r (0.98), R2 (0.96), and Adj R (0.95) in males, and r (0.88), R2 (0.78), and Adj R (0.77) in females. In combined predictors, the combination of CG and wither height (WH) yielded the highest values for r (0.99), R2 (0.99), and adj R (0.99) in males, and r (0.92), R2 (0.91), and adj R (0.83) in females. The most accurate prediction of body weight in Kuantan cattle was achieved by combining two body measurements, CG and WH. Using the regression equation for estimating body weight proved to be more accurate than the School formula

Abstract

Bioherbal, a feed additive made from rhizome extract, exhibited promising capabilities in eradicating pathogenic bacteria residing within the digestive tracts of broiler chickens. The LpxC protein, a biosynthetic regulator of lipid A (a critical component of gram-negative bacterial cell walls), was the focus of this research. Our primary objective was to assess the bioactive potential of bioherbal as a prospective inhibitor of UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine (LpxC) by employing in silico methods. Computational analyses were employed to scrutinize the interactions between the LpxC protein and various ligands on Bioherbal. Molecular docking served as the initial screening process, evaluating 48 bioactive compounds based on energy affinity, conformation values, and interactions with protein residues. The three compounds exhibiting the lowest binding affinities were subjected to molecular dynamics simulations. Molecular docking analysis revealed that most of the screened compounds exhibited low binding affinity for LpxC. Elephantorrhizol, zedoraldehyde, glechomanolide, demethoxycurcumin, curcumin, hexahydrocurcumin, gweicurculactone, germacrone, and 1,2-dihydrocurcumin exhibited lower binding affinities (<-7 kcal/mol). Elephantorrhizol, curcumin, and hexahydrocurcumin were selected for further analysis via molecular dynamics due to their similarity to native ligands. Molecular dynamics simulations revealed stable interactions of LpxC. In summary, these findings suggested that Bioherbal possesses the potential to function as an LpxC inhibitor, thereby offering a promising avenue for preventing the proliferation of gram-negative bacteria within the digestive tracts of broiler chickens. This computational study paves the way for further experimental investigations in this domain.
