Abstract

This study evaluated the sorghum “Samurai Two” production for feed harvested at different times after planting during the rainy season. A randomized block design was employed with five groups and five treatments representing different harvesting ages: 90, 95, 100, 105, and 110 days after planting. The variables measured included panicle length, weight, dry weight, seed dry weight per panicle, 1000-seed weight, number of seeds, dry seed production, total fresh and dry weight of panicles, moisture content, and total fresh and dry weight of straw biomass. Harvesting between 90 and 100 DAP resulted in a higher fresh and dry panicle weight, fresh and dry biomass, seed dry weight per panicle, 1000-seed weight, and dry seed production. The optimal seed production for “Samurai Two” occurred at 90 DAP during the rainy season. Conversely, harvesting at 95 DAP significantly increased straw biomass's total fresh and dry weight, with this age being optimal for straw biomass production.

Abstract

This study aimed to evaluate the feeding practices and nutritional intake of Ongole crossbred (PO) cattle in Kebumen, Central Java. This study focused on body condition scores (BCSs) and their implications for cattle performance. The parameters observed in this study included the feed composition, nutrient content, and impact of different BCSs on nutrient intake. The results of this research revealed that PO cattle with poor BCS did not receive sufficient feed, resulting in suboptimal nutrient intake. Moreover, those with medium BCS receive sufficient feed but still lack protein intake. In contrast, PO cattle with optimum BCS demonstrated the higher performance compared to other BCS groups, with crude protein intake of 0.57 kg (8.81%), 0.15 kg of extract (2.32%), 2.08 kg of crude fibre (32.15%), 3.81 kg of neutral detergent fiber 58.89%), 2.27 kg of acid detergent fiber (35.08%), and 4.00 kg of total digestible nutrient (61.82%) of the total dry matter intake, amounting to 6.47 kg. The findings underscore the importance of proper feeding practices tailored to the nutritional needs of cattle to optimize cattle performance

Abstract

Sorghum (Sorghum bicolor L. Moench) has the potential as a high-nutritional forage for livestock and can withstand drought conditions. This research aimed to analyze the effectivity and efficiency of each stage in the sorghum production process. The research was conducted from 2023 to 2024 at the Jonggol Animal Science Teaching and Research Unit (JASTRU). An exploratory and observational approach was established following with the snowball-sampling method and Data Envelopment Analysis (DEA) with a Variable Return to Scale (VRS) model as an analysis tool. The research indicated that March had the highest effectivity value in achieving the sorghum production target, with an efficiency score of one (optimum) at each stage of sorghum production. However, improvements were necessary in land preparation, planting, maintenance, and harvesting sorghum forage in other months. Environmental factors were influencing sorghum production that contributed to the highest increase in March. The sorghum production process in March could establish as a standard for maximizing productivity in the next cycle or ratoon. The research concluded that sorghum reached the best results in March, with the highest production effectivity and an optimum efficiency value at every stage of production in the private company.

Abstract

Small dairy farms in tropical regions frequently encounter feed shortages and quality fluctuations between seasons, which can substantially affect milk production. This research aimed to evaluate the ability of small-scale dairy farms to adapt to and manage feed fluctuations in response to seasonal changes.  The research employed an exploratory design, with samples collected using nested sampling methods. Three samples were collected according to the season, specifically during the dry season (August 2024) and the rainy season (January 2025), from the Cepogo and Selo Subdistricts in Boyolali.  Feed samples collection was conducted in five stages: 1) desk study of the research area; 2) field visiting; 3) feed samples; 4) forage samples collection; and 5) feed analysis using proximate analysis (AOAC, 2005).  The results showed differences in feeding management among farmers related to their dairy animal structures.  The highest dry matter content in the forage was found in rice straw (60.4% DM), which dominated dry season use, while the highest crude protein content was observed in calliandra (23.5%) among the forages. Five coproducts have high dry matter content with varying crude protein and crude fibre levels.  The research concluded that small-sized dairy farms can adapt and manage feed fluctuations based on seasonal changes by making forage and concentrate choices available.

Abstract

Farmers in Indonesia utilize a substantial amount of rice straw to provide feed for their livestock but restricted in terms of its low nutritional value. This study was conducted with objective to evaluate the quality of rice straw silage with addition of sacha inchi (Plukenetia volubilis L.) meal and sambung nyawa (Gynura procumbens) leaves based on physical, chemical, and microbiological properties. The study employed a completely randomized design with 9 treatments (P0: 100% rice straw, P1: 90% rice straw + 10% sacha inchi meal, P2: 85% rice straw + 15% sacha inchi meal, P3: 80% rice straw + 20% sacha inchi meal, P4: 75% rice straw + 25% sacha inchi meal, P5: P1+10% sambung nyawa leaves, P6: P2+10% sambung nyawa leaves, P7: P3+10% sambung nyawa leaves, P8: P4+10% sambung nyawa leaves) and 5 replications, incorporating the addition of sambung nyawa leaves. The variables examined include the physical quality i.e. colour, flavour, texture, and presence of mold; chemical quality i.e. pH, crude protein (CP), and crude fibre (CF); and microbiological quality i.e. lactic acid bacteria (LAB), yeasts, aerobic bacteria, and pathogenic bacteria. The results of the physical quality test indicated that the addition of sacha inchi meal and sambung nyawa leaves resulted no significant difference. On the other hand, the chemical quality showed that the addition of sacha inchi meal and sambung nyawa leaves have enhanced the rice straw silage nutritional content (p<0.05) particularly CP content by about 4 fold. The microbiological tests showed that the addition of sacha inchi meal and sambung nyawa leaves had an impact on the preservation of silage by inhibiting the growth of pathogenic microorganisms. It is concluded that the quality of rice straw silage has improved by the addition of 10-25% sacha inchi meal and 10% sambung nyawa leaves
