Abstract

Roselle calyx powder (RCP) can act as natural dietary additives in a concentrate. A completely randomized design was employed in this study to determine the impact of 6 different doses of RCP supplementation (0, 0.1, 0.2, 0.4, 0.8, and 1.6%) in a rice straw-based diet using 6 replicates (n = 6) on in vitro dry matter degradability (IVDMD), in vitro organic matter degradability (IVOMD), pH, total gas production 8 hours (TGP8), total gas production 16 hours (TGP16), total gas production 24 hours (TGP24) and methane. RCP supplementation did not affect the degradability, pH, and methane. The lower dose of RCP-0.1 supplementation obtained greater TGP than the higher doses, increased TGP can be a sign of increasing rumen fermentation process. However, higher doses RCP are not recommended, as the bioactive compounds may act as antinutrients, inhibiting the fermentation process.

Abstract

Duck eggs which are processed into salted eggs by the salting method have various advantages, but it cannot be stored for a long time. Efforts that can be made to increase shelf life, improve characteristics, and increase nutritional content include making salted egg whites in the form of powder. Egg powder can be made by drying using an oven, so a stabilizer is needed to reduce damage due to heating. Carboxyl Methyl Cellulose (CMC) is a stabilizer that can be used because it has good hydrophilic properties. The research objective was to improve the physicochemical quality and nutritional content of salted egg white powder (SEWP) so that it can be used as a form of functional food diversification. The research method used a laboratory experiment with a completely randomized design with 4 treatments and 5 replications. The research material is salted egg white and CMC according to the treatment of 2%, 4%,6%, and control. The addition of CMC to salted egg white powder had a very significant (P<0.01) effect on physicochemical quality and also had a significant effect (P<0.05) on the pH value. Based on the research results, 6% CMC added to egg white powder can improve the physicochemical characteristics.

Abstract

The study examined the association between TLR1A gene polymorphism in exon 4 and the performance of Gray Sentul chickens. Conducted at the Jatiwangi Poultry Breeding Development Center. DNA from 30 males and 30 females was analyzed using PCR and sequencing to identify Single Nucleotide Polymorphism (SNPs). Data processing employed BioEdit and MEGA 11. Results revealed five mutations in males (g.775T>C, g.844 T>A, g.858C>T, g.983C>T, and g.1163G>A) and three in females (g.721G>A, g.983C>T and g.1163G>A). Males showed higher body weights, with optimal growth at 1–2 months. Peak egg production occurred at 41 weeks (HDP 44.97%), and the highest egg weight (46.93 g) at 55 weeks. Specific SNPs associated with performance traits include g.775T>C for body weight in males, g.1163G>A for body weight in females and egg production, and g.721G>A and g.983C>T for egg weight. This study concludes that the TLR1A gene can be used as a genetic marker to improve the performance of grey Sentul chickens.

Abstract

The aim of this study was to examine the effect of the level of seaweed (Padina australis) as a ruminant feed on the nutritional quality and fiber fraction of complete diets. The variables observed were dry matter, crude protein, crude fiber, crude fat, extract material without nitrogen, ash content, acid detergent fiber and neutral detergent fiber. This study was based on a completely randomized design (CRD) with 4 treatments and 4 replications, namely P0 = complete feed (control), P10 = complete feed with 10% Padina australis level, P20 = complete feed with 20% Padina australis level, and P30 = complete feed with 30% Padina australis level. The results showed that the use of Padina australis up to 30% can increase dry matter, crude protein and reduce crude fiber, crude fat and ash content as well as neutral detergent fiber and acid detergent fiber content. The use of Padina australis at 20% level is the best treatment because it can reduce crude fat 6.21%, ash content 16.56%, neutral detergent fiber 50.88% and acid detergent fiber 31.22%.

Abstract

AbstractThis research aims to evaluate differences in soil nitrogen content, nitrogen absorption by plants, and forage production of Calopogonium mucunoides plants grown on andosol and ultisol soils during a 90-day planting period. The research method used was experimental, with treatment factors in the soil type (andosol and ultisol). The parameters observed included the soil’s moisture, temperature, pH, nitrogen content, and the plant’s nitrogen content and forage production. The results showed that Andosol's average soil moisture value (53.61%) was higher than Ultisol (43.68%). The soil temperature of Ultisol (24.34°C) tends to be higher than Andosol (23.36°C). Andosol soil pH (5.04) exceeds Ultisol's (4.87). The soil nitrogen content in Andosol (4,838%) is higher than in Ultisol (4,058%). The nitrogen content in plant tissue in both soil types is relatively the same, namely (2.423%) for andosol soil and (2.523%) for ultisol soil. However, forage production on Andosol (42.65 g/pot fresh weight; 11.85 g/pot dry weight) was almost 2 times higher than Ultisol (21.75 g/pot fresh weight; 5.907 g/pot dry weight). Nitrogen uptake in andosol soil is 0.247 grams/pot, higher than in ultisol soil, 0.149 grams/pot. In conclusion, Andosol is more optimal for the growth of C. mongoides in forage production.

Abstract

Beta-lactoglobulin genetics is one of the whey proteins in cow's milk that can influence improvements in milk composition, production, and component levels. Reproductive disorders and clinical mastitis in livestock are often related to genetic, hormonal, and environmental factors. Research on the relationship between beta-lactoglobulin and cow reproduction is still very limited. Therefore, the aim of this study is to determine the relationship between beta-lactoglobulin genotype and clinical mastitis as well as reproductive disorders (dystocia, retained placenta, and endometritis). This research utilizes secondary data obtained from the KPBS Pangalengan headquarters, consisting of genotype examination results of betalactoglobulin and medical records of cows experiencing clinical mastitis and reproductive disorders. A total of 113 samples were collected. The data were analyzed using quantitative methods, followed by ChiSquare tests using Microsoft Excel and SPSS version 25.0 for data analysis. The results showed that the beta-lactoglobulin genotype was not associated with the incidence of clinical mastitis (p=0.509) or reproductive disorders such as dystocia (p=0.789), retained placenta (p=0.193), and endometritis (p=0.685). All test results indicated significance values ≥0.05. The conclusion of this study is that polymorphism beta-lactoglobulin does not have a significant relationship with clinical mastitis and reproductive disorders occurring in Friesian Holstein cows at Pangalengan area. Keywords: beta-lactoglobulin, clinical mastitis, dystocia, endometritis, Friesian Holstein cow, retained placenta.

Abstract

This study aims to determine the effect of microbiome inoculation on the growth and biomass ratio of corn crop-producing baby corn and forage. This research was conducted in the Ciparanje research field and Animal Food Plant Laboratory Faculty of Animal Husbandry, Padjadjaran University. The method used was an experimental method with a completely randomized design (CRD) consisting of six treatments and four replicates in each treatment. The treatments consisted of P1= BP4, P2= Probiotic LAB, P3= Mycofer (arbuscular mycorrhizal fungi), P4= BP4 + Mycofer, P5= LAB + Mycofer, P6= BP4 + LAB + Mycofer. There are five parameters observed, consisting of plant height every week, number of leaves, age of plant at tassel emergence, leaf to stem ratio (LSR), and shoot to root ratio. The data were then analyzed using Analysis of Variance (ANOVA), and if it showed significant results, it was continued with Duncan's further test. The results showed no significant effect of microbiome inoculation on, age of plant at tassel emergence and leaf to stem ratio. Significant results were obtained in the 9th-week plant height parameter (best in P5 at 158.25 cm), number of leaves (best in P5 at 15.75) and shoot to root ratio (best in P6 at 1.58). Overall, it can be concluded that microbiome inoculation can increase nutrient use efficiency and reduce inorganic fertilizers by as much as 50%, supporting environmentally friendly and sustainable agricultural and livestock practices.

Abstract

AbstractFeed in the form of pellets is one form of preservation of feedstuffs that is more guaranteed in terms of procurement and continuity of supply to maintain feed quality. This study aims to determine the effect of the level of cassava flour in pellets of calliandra and lamtoro mixture as a binder on physical properties and on the content of dry matter, organic matter, and crude protein. The study used an experimental method with a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments consisted of P0 (100% mixture of calliandra and lamtoro + 0% cassava flour), P1 (90% mixture of calliandra and lamtoro + 10% cassava flour), P2 (80% mixture of calliandra and lamtoro + 20% cassava flour), and P3 (70% mixture of calliandra and lamtoro + 30% cassava flour). The study showed that the treatment had a significant effect  (P < 0.05) on durability (87.40% to 77.88%) and crude protein (22.33% to 16.39%) and had no significant effect (P > 0.05) on specific gravity, pile density, pile compaction density, dry matter and organic matter content. From the results of the study, it can be concluded that the P0 (100% mixture of Calliandra and lamtoro) treatment produced the highest durability and crude protein values.

Abstract

One of the major challenges in ruminant production in Indonesia is ensuring the availability of high-quality and adequate forage. Identifying forage varieties with good nutritive value that adapt well to local climate conditions is crucial. This study evaluated the nutrient composition, fiber fractions, and in vitro rumen fermentation of Mulato grass harvested at different cutting ages (30, 40, and 50 days) in the lowlands of West Java, Indonesia. The nutrient content, analyzed using proximate and fiber fraction analysis, showed no significant differences across cutting ages except for ash content, which was lower at 40 days. Mulato grass cut at 30 days had lower acid detergent fiber (ADF), neutral detergent fiber (NDF), acid detergent lignin (ADL), and hemicellulose levels, while its cellulose content was higher compared to grass cut at 40 or 50 days. Rumen fermentation results indicated that grass cut at 30 days had higher in vitro dry matter digestibility (IVDMD), organic matter digestibility (IVOMD), and total volatile fatty acids (TVFA). These findings suggest that Mulato grass harvested at 30 days offers better digestibility and rumen fermentation outcomes, making it a suitable forage choice for ruminants in the lowlands of West Java, Indonesia.
